Instrumentations

Activation of a combination of devices

Activation of a combination of devices is made when opening a driver's door, turning a key in the ignition lock in situation 1 or 2, pressing the turn-push handle of dumping of indications of the counter of the current run (1) and inclusion of illumination of salon (see the Section Governing bodies and the equipment of salon).

Adjustment of intensity of illumination of devices

Adjustment of intensity of illumination of devices (at the included running fires - see the Section Governing bodies and the equipment of salon) is made by means of the turn-push handle (1) which is built in at the left in a combination of devices, - by means of the same handle activation of a combination of devices (see above) and dumping of the indication of the counter of the current distance in kilometers can be made (see below).

Fuel reserve measuring instrument

The measuring instrument (5) is in the right corner of a combination of devices and serves for visual monitoring of a reserve of the fuel remaining in a tank.

The error of indications of the measuring instrument of a reserve of fuel is minimum when the car holds strictly horizontal position. At movement of the car along twisting or hilly roads the error of the device increases. Functioning of the measuring instrument does not depend on position of the ignition key. The tag 1/1 corresponds to a condition of full gas station, R - an empty tank (with a reserve stock). The control lamp which is built in the measuring instrument dial with the image of the gas station informs the driver on need at the first opportunity to make refueling of the car.

In the left bottom corner of the dial of the measuring instrument control lamps of SRS are built in and "Fasten belts" (see below).

Speedometer

The speedometer is located in the central part of a combination of devices and shows the speed of the movement of the car in km/h.

In the dial of a speedometer are placed the panel of control lamps / light indicators the multipurpose display of the on-board computer.

Tachometer

The tachometer is to the left of a speedometer and shows the frequency of rotation of a bent shaft of the engine in thousands of revolutions per minute (the indication should be multiplied on 100). In order to avoid an exit of the engine it is out of operation forbidden to exceed the most admissible frequency of rotation of a bent shaft (the arrow of a tachometer never has to come into a red zone of a scale).

For the purpose of protection of the engine at achievement turns of a bent shaft of range of red marking carry out a fuel supply cut-off.

In the right bottom corner of the indicator of a tachometer control lamps of raising of a parking brake / falling of level of brake fluid and ABS are built in (see below).

Fields of indication of the basic page of the multipurpose display of the on-board computer

The instruction for use of the on-board computer is provided in the operation manual on the car, - ask in shops of automobile literature.

Odometer and counter of a distance in kilometers of the current run

Scheme of an arrangement of fields of indication of the basic page of the multipurpose display of the on-board computer

2 — the Indication of the odometer
3 — Temperature of external air
4 — the Chronometer

5 — Position of the lever of the selector/range of switchings of AT
6 — the Indicator of the chosen mode of the transfer case

Fields of indication of the odometer (2) and the counter of the current run (1) are located one over another in the central part of the basic page of the multipurpose display. The odometer registers the general vehicle mileage from the moment of input it in operation, the dumped counter of the current run allows to trace a distance in kilometers of a concrete trip of the car (from the moment of the last zeroing of indications).

For dumping of indications of the counter it is necessary to activate a combination of devices, then to press the turn-push handle which is built in in the left corner of a combination of devices and to hold it pressed within about 1 second.

On the display the basic page has to be cut.

Indicator of temperature of external air

The field of indication of indications of the sensor of temperature of external air (3) is in the left bottom corner of the basic page of the multipurpose display. Temperature is defined in degrees Celsius (°C).

Change of indications after departure from a garage happens to the certain delay caused by inertia of adaptation of the sensor.

Besides, the compulsory delay of increase of indications according to increase in ambient temperature at a temperature of cooling liquid of the engine is provided over 60 °C, - that allows to prevent aimings from the hot engine during stops and at the movement of the car with small speeds.

Chronometer

Under indication of indications of an onboard chronometer the right bottom corner of the basic page of the multipurpose display is taken away. The regulator of installation of indications of a chronometer is located under the tachometer dial at the left (see in the same place). Rotation of the regulator extended from the panel clockwise leads to increase in indications, against - to reduction.

Indicator of position of the lever of the selector/range of switching of AT

The field of indication of the current range of AT (5) is located in the left top corner of the basic page of the multipurpose display. The symbol corresponding to the chosen position of the lever of the AT selector is in the field highlighted ("Р", "R", "N" or "D").

The indicator of the chosen mode of the transfer case

The field of indication of the current mode of the transfer case (6) is located in the left top corner of the basic page of the multipurpose display, directly over the field of indication of the current range of AT (4). The symbol corresponding to the chosen mode of the transfer case is in the field highlighted ("N", "L" or "N").

Control lamps and light indicators

The whole complex of control lamps and indicators by means of which the driver obtains important information on serviceability/violation functioning of the main units and systems of the car is built in assembly of a combination of devices of the car. The scheme of an arrangement of control lamps on an instrument guard is submitted on the illustration Design of a Combination of Devices . One more control lamp (a power supply system filter settler) is located on the central console ahead of the AT selector lever.

Location of a control lamp of a settler of the filter of a power supply system

Below information on the principle of functioning of each of the provided light indicators separately is offered to attention.

The list of the devices of control lamps and light indicators which are a part of a combination

Control lamps and light indicators are built in in dials of measuring instruments of a combination of devices (A design of a combination of devices).

— (Green) Light indicators of indexes of turns / alarm system

— (Yellow) Control lamp of failures of the system of anti-blocking of brakes (ABS)

— (Red) Control lamp of level of brake liquid / refusals of brake system / indicator of raising of the parking brake

— (Yellow) Precautionary control lamp of antiprobuksovochny (4-ETS)/antistrange (ESP)/anti-blocking (ABS) of systems ("Adapt style of driving to road conditions!")

— (Yellow) Control lamp of refusals of MIL/" check the engine"

— (Yellow) Light indicator of activation of the Speedtronic system

— (Blue) Light indicator of activation of driving beam of headlights

— (Yellow) Control lamp of preheat of the diesel engine

— (Red) Light indicator "Fasten a Seat Belt"

— (Red) Control lamp of system of additional safety (SRS)

Light indicators of indexes of turn / alarm system

The light indicators issued in the form of arrows have a green luminescence and serve for control of serviceability of functioning of the corresponding indexes of turns. The direction of indicator arrows coincides with the chosen direction of change of course of the car. Indicators work in the flashing mode with a frequency, the corresponding frequency of a blinking of indexes of turn. The speeded-up blinking of one of indicators usually demonstrates burn-out of a lamp of one of indexes of the corresponding turn, - at the first opportunity make replacement of the burned-down lamp not to create emergencies on roads.

Turning on of the alarm system usually is followed by a simultaneous blinking of indicators of indexes of both turns.

Control lamp of system of anti-blocking of brakes of ABS

This control lamp serves for control of serviceability of functioning of ABS, quickly works at inclusion of ignition and has to die away several seconds later after implementation of start of the engine. The refusal of a lamp of shutdown, and also its activation during the movement demonstrates violation of serviceability of functioning of system of anti-blocking of brakes, - the car should be driven away immediately on HUNDRED companies Mercedes-Benz for performing diagnostics and performance of necessary recovery repair.

Along with ABS also systems 4-ETS and ESP are disconnected) that has to be confirmed by operation of the corresponding control lamp (see below).

Control lamp of level of brake liquid / refusals of brake system / indicator of raising of the parking brake

The control lamp continuously burns at raising of the parking brake, reminding the driver of need of his otpuskaniye before a start of motion. The movement with the cocked parking brake leads to a bystry overheat and failure of brake mechanisms of back wheels of the car, and also to premature wear of protectors of tires of back wheels, but also, can become a cause of infringement of serviceability of functioning of system of anti-blocking of brakes (ABS).

If the control lamp continues to burn after an otpuskaniye of the parking brake, or works during the movement, it usually demonstrates excessive falling of level of brake fluid, - one of the possible reasons of gradual decrease in level of brake fluid is normal wear of frictional overlays of brake shoes.

Short-term operation of a control lamp happens also at inclusion of ignition (even at the released parking brake).

Precautionary control lamp of antiprobuksovochny (4-ETS)/antistrange (ESP)/anti-blocking (ABS) of systems

The system 4-ETS is activated at speeds from 40 to 80 km/h at achievement any of wheels of a limit of coupling of the tire with the road (for example, at unilateral ice). The corresponding wheel at the same time is braked for the purpose of ensuring reliable traction effort.

This control lamp is quickly activated at inclusion of ignition and has to go out right after implementation of start of the engine. Compulsory shutdown of antistrange (ESP) system is followed by operation of this control lamp (see the Sections Traction control system (4-ETS), Electronic antistrange system (ESP)). The refusal of a lamp of shutdown, and also its activation during the movement demonstrates violation of serviceability of functioning of systems 4-ETS/ESP/ABS, - the car should be driven away immediately on HUNDRED companies Mercedes-Benz for performing diagnostics and performance of necessary recovery repair. Activation of a lamp in the flashing mode during the movement of the car warns the driver that wheels of the car are on a limit of coupling with a paving and it is necessary to reduce speed to safe level.

At high load of brake mechanisms there is an automatic short-term shutdown of system 4-ETS for the purpose of prevention of an overheat of brakes, - this shutdown is followed by activation of a control lamp.

At towage of the car with the back wheels which are torn off from the earth, and also when checking serviceability of functioning of brake mechanisms at the stand the engine has to be killed since otherwise the active braking influence of the ESP system can lead to failure of brake mechanisms of back wheels!

Control lamp of refusals of MIL ("Check the engine")

This control lamp quickly works at inclusion of ignition and has to die away several seconds later after implementation of start of the engine. The refusal of a lamp of shutdown, and also its activation during the movement demonstrates violation of serviceability of functioning of control systems of engine/decrease in toxicity of the fulfilled gases, - the car should be driven away immediately on HUNDRED companies Mercedes-Benz for performing diagnostics and performance of necessary recovery repair.

For shutdown of the control lamp activated after gas station of completely devastated fuel tank it is necessary to repeat three-four times the procedure of start of the engine.

Light indicator of activation of the Speedtronic system

This indicator serves for confirmation of activation of the mode of variable restriction of speed of a tempostat (Speedtronic) (see the Section of the Control system of the speed (Tempostat/Speedtronic)).

Light indicator of activation of driving beam

This indicator serves for confirmation of activation of driving beam of headlights.

Control lamp of preheat of the diesel engine

The control lamp of preheat lights up at inclusion of ignition and demonstrates activation of system of preheat. Start of the engine has to be carried out not earlier than the control lamp is disconnected.

Light indicator "Fasten a Seat Belt"

This indicator has an amber luminescence and quickly (approximately for 6 seconds) works inclusion of ignition, reminding the driver and passengers of need of fastening by seat belts.

Control lamp of system of additional safety (SRS)

This control lamp approximately for 4 seconds lights up at inclusion of ignition and has to die away right after implementation of start of the engine. If the lama continues to burn at the working engine (in the constant or flashing mode), it indicates existence of malfunction of components of the SRS system. At the corresponding complete set operation of this control lamp can be the testimony of malfunction in contours of side and head safety cushions, or devices of automatic emergency natyazhitel of seat belts.

Control lamp of a moisture separator of a power supply system

The control lamp is located in a forward part of the top cover of the central console of the car (see the illustration Location of a Control Lamp of a Settler of the Filter of a Power Supply System), to work quickly at inclusion of ignition and serves for the warning of the driver of need of implementation of the procedure on removal of moisture from fuel. At refusal of a lamp of shutdown after implementation of start of the engine or its operation during the movement follows at the first opportunity to address on HUNDRED Mercedes-Benzs.

Long operation of the car with the burning control lamp of a moisture separator can lead to serious internal damages of the engine, to the recovery repair interfaced to which guarantee certificates of manufacturers do not extend!
