2.3.2. Combination of devices

The set of the main measuring instruments, control lamps and light indicators is included in a combination of devices of an instrument guard of the car.


Scheme of an arrangement of elements of a combination of devices


Measuring instruments


Speedometer, odometer and run measuring instruments

The speedometer is located on the right in the central part of an instrument guard (see an illustration the Scheme of an arrangement of elements of a combination of devices) and specifies speed of movement of the car in miles at an o'clock (the main scale) and kilometers per hour (the additional scale, is lower than an axis of a display arrow, under a control lamp of SRS "AIR BAG" the three-functional digital display of the odometer, and two independent measuring instruments of run is located.

The three-functional digital display of odometers / measuring instruments of a distance in kilometers of the current run is activated at ignition inclusion (a key will turn in the situation ON). In an odometer mode on the screen of the display information on complete run of a vehicle is deduced from the moment of the beginning of its operation. Measuring instruments of run And and In allow to make two independent measurements. The choice of a mode of functioning of the display is made by means of the speedometer of the press switch located on the right under the dial — in the right bottom display space the corresponding explanatory inscription is highlighted. Switching is made in the following order: ODO — TRIP A — TRIP B — ODO. For dumping of indications of the display it is necessary to hold the button of the switch in any of modes pressed during more than 1 second.


Tachometer

More to the right of a speedometer in the central part of an instrument guard the index of turns of the engine — a tachometer (see an illustration the Scheme of an arrangement of elements of a combination of devices) is located. The arrow of a measuring instrument shows to the driver frequency of rotation of a cranked shaft of the engine in thousand revolutions per minute. Try not to allow hits of an arrow of a measuring instrument in limits of the range of a scale of a measuring instrument allocated with red color — at dangerous increase in turns be switched to higher transfer.


Measuring instrument of temperature of cooling liquid

The measuring instrument is located the right bottom corner of an instrument guard (see an illustration the Scheme of an arrangement of elements of a combination of devices) and registers temperature of cooling liquid of the engine. Indications of a measuring instrument can vary depending on ambient temperature and driving conditions. At an exit of an arrow of the device out of limits of a range of admissible values of a scale, it is necessary to stop immediately movement and let's to the engine cool down. Long operation of the peregrety engine can lead to an exit it out of operation.


Measuring instrument of a stock of fuel

The measuring instrument of fuel consumption is located in the left bottom corner of an instrument guard (see an illustration the Scheme of an arrangement of elements of a combination of devices) and shows approximately fuel level in a tank. During the braking, accelerations, commission of maneuvers and car movement on the inclined plane of the indication of a measuring instrument can vary slightly. The scheme of connection of a measuring instrument such is that it continues to give out working value even at the switched-off ignition (a key in the situation OFF). When lowering level of fuel in a tank to critical value the control lamp works built in in the measuring instrument dial. Try not to allow complete production of the fuel which was in a tank — in due time make car filling.


Movement with very low level of fuel in a tank can lead to operation of a control lamp of refusals (MIL) (see below). At pass of small distance after refueling the control lamp should go out! If the lamp continues to burn, the car should be driven away on car repair shop for carrying out diagnostics and performance of necessary regenerative repair.


Control lamps and alarm buzzers


Designations of control lamps and light indicators

The whole complex of control lamps by means of which the driver receives important information on serviceability / violation functioning of the main units and car systems is built in assembly of a combination of devices of the car. The full list used on models of control lamps considered in the real Management and light indicators is provided in the table (see above). Below information on a principle of functioning of each of the provided light indicators separately is offered to attention of the reader.


Check of serviceability of lamps

Cock the parking brake and include ignition (the engine do not start) — on an instrument guard control lamps of pressure of oil, a charge, brake system and ATF temperature, a control lamp of engine failures (MIL), and also the alarm indicator of an all-wheel drive mode should light up.

Besides should join quickly and soon go out control lamps of SRS, ABS, switching off of the O/D mode, inclusion of an all-wheel drive mode, engine failures and inclusion of a 4LO mode of a transfer case, and also (at the corresponding complete set) light indicators of modes of a communicator of Infiniti.

If any of the listed lamps does not work, therefore, it failed, or there was a break in a chain of its electroconducting. Try to reveal and eliminate a cause of failure.


Control lamp of ABS

This control lamp lights up approximately for some seconds at inclusion of ignition and should go out later the specified term, or right after implementation of start of the engine, confirming with that serviceability of functioning of a contour of system of anti-blocking of brakes.

Refusal of switching off of a lamp, no less than its operation in any other situations testifies to identification by system of self-diagnostics of violations in ABS contour. The car should be driven away immediately on the next car repair shop for carrying out detailed diagnostics of system and performance of necessary regenerative repair.

At operation of a control lamp the system of anti-blocking of brakes is disconnected, however brake mechanisms of the car continue to function in a usual mode, providing a vehicle adequate braking.


Control lamp of temperature of ATF

This control lamp lights up at inclusion of ignition and should go out right after implementation of start of the engine, confirming with that serviceability of functioning of the corresponding alarm chain.

Lamp operation during movement testifies to a dangerous overheat of transmission liquid and need of immediate decrease in speed of movement (without violation of traffic regulations).

Long operation of a vehicle with the included control lamp is fraught with failure of automatic transmission!


Alarm indicator of refusal of inclusion of the AT parking function

Activation of this control lamp warns the driver that there was no inclusion of parking function of automatic transmission.

If the transfer case is not fixed in one of working provisions at transfer of the lever of the AT selector to the situation "R", blocking of wheels does not occur.

The control lamp can light up at ignition inclusion (a key in the situation ON) if AT is transferred to the situation "R" when finding the switch of modes of functioning of a transfer case (4WD) in situation, intermediate between 4Н and 4L. Transfer the 4WD switch to any of working provisions (2Н, AUTO, 4Н or 4LO) and make sure of operation of a control lamp of inclusion of an all-wheel drive mode (4WD).

Before a parking of the car watch, that the lever the selector / switch of modes of a transfer case was in situation H or 4LO, or that the control lamp of activation of an all-wheel drive mode (4WD) was included. Do not forget to cock the parking brake!
Operation of the ATR alarm indicator testifies to refusal of inclusion of the AT parking function and finding of a transfer case in neutral situation!
Refusal of switching of a transfer case can bring into situation 2Н, AUTO, 4Н or 4LO to a spontaneous skatyvaniye of the parked car!


Control lamp of level brake liquids / raisings of the parking brake

This control lamp continuously burns when raising the parking brake, reminding the driver of need of his otpuskaniye before a start of motion.

Movement with the cocked parking brake leads to a fast overheat and failure of brake mechanisms of back wheels of the car and premature wear of protectors of tires of back wheels, and, besides, can become a cause of infringement of serviceability of functioning of system of anti-blocking of brakes (ABS).

One of the possible reasons of gradual decrease in level of brake liquid is normal wear of frictional overlays of brake shoes. At operation of a control lamp the car should be driven away on the next car repair shop for an assessment of a condition of blocks and check of tightness of a hydraulic path of brake system.

Operation of a control lamp occurs also at ignition inclusion, even at the released parking brake.

Movement with the included control lamp dangerously! First of all make sure that the parking brake is released.


Control lamp of a charge of the storage battery

This control lamp lights up at inclusion of ignition and should go out right after implementation of start of the engine, confirming with that serviceability of functioning of a chain of a charge.

Operation of a control lamp at the working engine warns the driver about violation of serviceability of functioning of system of a charge (i.e., the storage battery starts to be discharged). It is necessary to switch off at once everything consumers of the electric power on which functioning safety of traffic does not depend, and to try not to allow останова the engine as attempt of its restart can lead to the final category of the battery. First of all check a condition of a driving belt of the generator. In case of need drive away the car on the next car repair shop for carrying out diagnostics of refusal and performance of necessary regenerative repair.


Control lamp of leaky closing of doors

The luminescence of this control lamp at the included ignition warns the driver what not all doors of the car are densely slammed.


Control lamp of pressure of impellent oil

The control lamp of pressure of impellent oil lights up at inclusion of ignition and should go out right after implementation of start of the engine, confirming with that serviceability of functioning of the corresponding alarm chain.

The lamp blinking at the working engine testifies to pulsatsionny decrease in working pressure of engine oil in the engine. Transition of the indicator to a mode of a constant luminescence says that pressure of oil fell to dangerously low level that is fraught with serious internal damages of the engine, up to its full exit out of operation. In both cases it is necessary to take urgent measures for correction of level of oil, identification and elimination of the reasons of pressure drop.

Movement continuation at the worked control lamp of pressure of oil is fraught with the most serious consequences, up to engine jamming!


Control lamp of an all-wheel drive mode

Detailed statement of modes of functioning of a control lamp of 4WD — see. Use of an all-wheel drive mode.


This control lamp is built in a tachometer (see an illustration the Scheme of an arrangement of elements of a combination of devices), lights up at inclusion of ignition and should go out right after implementation of start of the engine, confirming with that serviceability of functioning of the corresponding alarm chain.

Indicator operation during movement (both in continuous, and in a flashing mode) testifies to violation of serviceability of functioning of the relevant system (see. Operation receptions) — drive away the car on car repair shop.

Avoid movement on roads with a firm dry covering at the included modes 4Н or 4LO of a transfer case — if the 4WD light indicator works at the included AUTO mode or 4Н, transfer the 4WD switch to situation 2WD; at movement in a 4LO mode it is necessary to stop, transfer AT to the situation "N" and after it to include a 2WD mode. If after the made manipulations the alarm indicator continues to burn, the car should be driven away on the next car repair shop for carrying out detailed diagnostics of the corresponding knots and performance of necessary regenerative repair!


Control lamp of level of liquid of washing of glasses

At operation of this control lamp it is necessary to make correction of level of liquid in the tank of washing liquid.


Control lamp and alarm buzzer of seat belts

The control lamp is activated at inclusion of ignition and remains included until the driver's seat belt will not be properly clasped (see. Elements of passive safety). Operation of a control lamp is accompanied by a 6-second sound signal.


Control lamp of system of additional safety of SRS

This control lamp lights up at inclusion of ignition and should die away about 7 seconds later, or right after implementation of start of the engine.

Refusal of a lamp of switching off later the specified term, or continuation of its functioning at the working engine (in a continuous or flashing mode) indicates existence of malfunction of components of safety cushions of SRS. At the corresponding complete set operation of this control lamp can be the testimony of malfunction in contours of lateral safety cushions, or devices of automatic emergency natyazhitel of seat belts (see. Elements of passive safety).

The car should be driven away on the next car repair shop for carrying out complete diagnostics of SRS and performance of the corresponding regenerative repair in any of listed below situations:

  • The control lamp of AIR BAG is not disconnected on the expiration stipulated above term (7 seconds) after ignition inclusion, or continues to burn (in a continuous or flashing mode) at the working engine;
  • The control lamp is not activated at all at ignition inclusion;
  • The control lamp works (in a continuous or flashing mode) during car movement.

Safety cushions (face-to-face and lateral) at the activated control lamp can not work at emergency collision of the car!


Control lamp темпостата

At the corresponding complete set of the car this control lamp lights up at inclusion of system of automatic control by speed of movement of the car (темпостата) (see. Instructions for use control system of the speed (tempostaty)).


Light indicator of modes of a transfer case

Detailed statement of modes of functioning of the 4WD light indicator — see. Use of an all-wheel drive mode.


The indicator is built in a tachometer (see an illustration the Scheme of an arrangement of elements of a combination of devices), quickly lights up at inclusion of ignition and should go out right after implementation of start of the engine, confirming with that serviceability of functioning of the corresponding alarm chain.

At the working engine the indicator serves for control of a choice of modes of a full drive by means of the lever of the selector distributing the box / switch of modes of a transfer case of 4WD.

When switching modes of a transfer case the control lamp of 4WD can work in a flashing mode.


Control lamp of a reserve of fuel

This control lamp is activated, when in a fuel tank there are less than 9.0 l of fuel and warns the driver about need urgently to make car filling.


Light indicator of inclusion of a driving beam

This light indicator lights up at the same time with inclusion of a driving beam of head headlights of the car.


Control lamp of engine failures (MIL)

The control lamp lights up at inclusion of ignition and should go out right after implementation of start of the engine, confirming with that serviceability of functioning of the corresponding alarm chain.

Its operation during any other time testifies to possible malfunction of one of systems of electric equipment of the power unit. In the absence of visible signs of refusals of functioning of systems of the power unit and decrease in dynamics of the vehicle, lamps of violation fixed by activation can be at the bottom of increase in fuel consumption or increase of toxicity of emissions.

Violation of serviceability of functioning of elements of systems of decrease in toxicity of the fulfilled gases can be the reason of operation of a lamp of MIL also.

To lamp activation in a flashing mode leads leaky closing of a cover of a jellied mouth of a fuel tank, and also an approach by the end of a stock of fuel — check density of closing of a cover, make sure that in a fuel tank there is a fuel stock not less than 14 liters.

At operation of a control lamp in a continuous mode it is necessary to drive away the car on car repair shop for condition check for check of serviceability of functioning of control systems of engine / decrease in toxicity of the fulfilled gases.

The typical reason of activation of a lamp in a flashing mode is identification by the module of self-diagnostics of admissions of the ignition fraught with failure of components of systems of decrease in toxicity:

  • Continuing movement, try to move with a speed no more than 72 km/h;
  • Avoid sharp accelerations, try not to avoid moving on the hilly district;
  • Whenever possible as much as possible unload the car / trailer.

Ignoring of signals of a control lamp of MIL is fraught with serious damages of the engine, up to a unit exit out of operation. At operation of a control lamp under way it is necessary to stop immediately movement, to park in a safe place and to muffle the engine, then, later small time, to make start, watching thus behavior of a control lamp. If the lamp did not return to a normal mode of functioning and continues to burn, the car should be driven away on the next car repair shop for carrying out detailed diagnostics and performance of necessary regenerative repair. Before elimination of malfunction of systems of the engine try to move with moderate speed, avoiding sharp dispersals with complete squeezing of a pedal of gas.

Even if at engine restart the control lamp comes back to a normal mode (i.e., dies away), it is necessary to address at the first possibility for consultation on car repair shop, especially if such turning on of the indicator occurs not for the first time.


Continuation of operation of the car with the included control lamp of a condition of the engine can lead to premature failure of the catalytic converter. Remember that on refusals and the damages which have resulted operation of the car with the included control lamp, guarantee certificates of manufacturer do not extend!


Control lamp of switching off of a mode of raising transfer

The control lamp serves for indication of shutdown of a mode of raising transfer by a way of squeezing of the corresponding push-button switch.

The lamp lights up approximately for 2 seconds at inclusion of ignition and should go out later the specified term, or right after implementation of start of the engine, confirming with that serviceability of functioning of the corresponding alarm chain.

If later the stipulated term the control lamp continues to function in a flashing mode within 8 more seconds, the car should be driven away on car repair shop for carrying out detailed diagnostics of system and performance of necessary regenerative repair.

In a control system of AT the mode of the emergency functioning, allowing to continue movement even is realized at damage of an electric chain — transmission thus is automatically blocked on the third transfer. See also Features of driving of the car with automatic transmission.


Control lamp of a choice of a 4LO mode of a transfer case

This control lamp is built in a tachometer (see an illustration the Scheme of an arrangement of elements of a combination of devices), lights up approximately for 1 second at inclusion of ignition and should go out later the specified term, or right after implementation of start of the engine, confirming with that serviceability of functioning of the corresponding alarm chain.

The lamp serves for indication of transfer of the 4WD switch in situation 4LO (ignition should be included).

If at the chosen 4LO mode the control lamp passes to a flashing mode, it is necessary to stop movement, then slowly to get under way forward — the blinking should stop (for more details see. Part operation Receptions).

When finding the switch in situation between 4Н and 4LO it is necessary to stop, switch AT in the situation "N", then to translate the switch situation 4Н or 4LO — without performance of these manipulations transfer of the switch it is not obviously possible. Make sure of serviceability of operation of a control lamp at transfer of the 4WD switch to situation 4LO.

At the moment of switching the control lamp can work in a flashing mode.


Light indicator of indexes of turn / alarm system

The indicator confirms the fact and serviceability of functioning of indexes of turns of a vehicle and works in a flashing mode with the frequency corresponding to frequency of a blinking of indexes. Doubling of frequency of a blinking of the indicator usually testifies to a peregoraniye of a lamp of one of indexes of turns — it is necessary to make replacement of the burned-down lamp at the first possibility not to create emergencies on roads.

The blinking of this indicator usually accompanies also turning on of the alarm system.


The light indicator of a repeated call of the Communication Center (the models equipped with a communicator of Infiniti)

This light indicator lights up approximately for 30 seconds at inclusion of ignition and should go out later the specified term, confirming with that serviceability of functioning of the corresponding alarm chain.

The indicator confirms serviceability of activation of function of automatic repetition of a call of the Communication Center in unsuccessful attempt of initiation of connection.

The indicator can start to blink earlier than the control lamp which has been built in in the corresponding button of the block of a communicator (is activated see. Governing bodies and salon equipment).


The light indicator of an exit from an area of coverage of a telecommunication network (the models equipped with a communicator of Infiniti)

This light indicator lights up approximately for 30 seconds at inclusion of ignition and should go out later the specified term, confirming with that serviceability of functioning of the corresponding alarm chain.

The indicator serves for the alarm system about finding of a radio telephone out of an area of coverage of a network and impossibility of establishment of contact to the Communication Center (see. Governing bodies and salon equipment).


The light indicator of inclusion of a distress signal of "Mayday" (the models equipped with a communicator of Infiniti)

This light indicator lights up approximately for 30 seconds at inclusion of ignition and should go out later the specified term, confirming with that serviceability of functioning of the corresponding alarm chain.

The control lamp of the indicator is built in the corresponding button of a communicator and is activated when giving distress signal. At the working indicator the communicator will make transfer attempts on the Communication Center of distress signals of "Mayday" in the international code by all available channels of radiotelephone communication (see. Governing bodies and salon equipment).


The light indicator of inclusion of information mode (the models equipped with a communicator of Infiniti)

This light indicator lights up approximately for 30 seconds at inclusion of ignition and should go out later the specified term, confirming with that serviceability of functioning of the corresponding alarm chain.

The control lamp of the indicator is built in the corresponding button of a communicator and is activated in attempts of installation of the channel of data exchange with the Communication Center for all available channels of radiotelephone communication (see. Governing bodies and salon equipment).


Alarm buzzer «Take a key from the ignition lock»

The buzzer works during opening of a driver's door of the car at the key forgotten in the lock in the ignition lock.


Alarm buzzer «Do not forget to switch off a headlight»

The buzzer works during opening of a driver's door at the switched-off ignition and outstanding headlights.

The buzzer will work even if shutdown of headlights already occurred automatically — return the switch to the situation OFF.


Sound signal of wear of brake shoes

At limiting wear of a frictional material of blocks of disk brake mechanisms they start to publish high-frequency squeal during car movement (regardless of that, braking is applied or not). At the first possibility make replacement of blocks.
