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

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

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.

Control lamp of temperature of ATF

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).

Alarm indicator of refusal of inclusion of the AT parking function

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).

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

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.

Control lamp of a charge of the storage battery

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

Control lamp of pressure of impellent oil

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.

Control lamp of an all-wheel drive mode

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.

Control lamp of level of liquid of washing of glasses

Control lamp and alarm buzzer of seat belts

Control lamp of system of additional safety of SRS

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.

Control lamp темпостата

Light indicator of modes of a transfer case

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.

Control lamp of a reserve of fuel

Light indicator of inclusion of a driving beam

Control lamp of engine failures (MIL)

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.

Control lamp of switching off of a mode of raising transfer

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

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.

Light indicator of indexes of turn / alarm system

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)

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

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)

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)

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.

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.
