Instrumentations

Activation of a combination of devices

Activation of a combination of devices is made when opening door, by pressing one of built in in a combination on the right and to the left of a speedometer of devices of push-button switches, and also at ignition inclusion.

Adjustment of intensity of illumination of devices

Adjustment of intensity of illumination of devices (at included running fires - see. Undressed Access to a luggage compartment) it is made by means of built in in an instrument guard at the left under the dial of a speedometer of the turn-push handle, - by means of the same handle activation of a combination of devices and switching of modes of functioning built in a speedometer digital display/dumping of the indication of the counter of the current distance in kilometers can be made.

Measuring instrument of a stock of fuel

The measuring instrument is in the left corner of a combination of devices and registers the stock of fuel remaining in a tank.

The error of indications of a measuring instrument is minimum, when the car occupies strictly horizontal situation. At car movement on twisting or hilly roads the error of the device increases. Functioning of a measuring instrument does not depend on position of the ignition key. The label 1/1 corresponds to a condition of complete filling, 0 - to an empty tank. Built in the measuring instrument dial the control lamp with the image of a filling station informs the driver on need at the first possibility to make car refueling.

The combined measuring instrument of temperature of cooling liquid / the current expense of fuel/pressure of impellent oil

The three-functional combined measuring instrument is located to the right of a speedometer and serves for indication of value of temperature of cooling liquid of the engine (the left bottom sector), indications of a measuring instrument of the current fuel consumption (the top sector) and indications of the sensor of pressure of oil (the right bottom sector).

Measuring instrument of temperature of cooling liquid

In normal conditions temperature of boiling of cooling liquid (antifreeze with the anticorrosive additives added in it), filled in calculated on functioning at superfluous pressure the path of system makes near 130°С. Under trying conditions operation, for example, in very hot weather or at long lifting uphill the arrow of the index can rise to the top red mark in a scale. If the temperature of the engine increased so that the arrow of the index comes into limits of a red range of a scale of a measuring instrument, it is necessary to stop immediately movement, to move down on a roadside, to park and make check of a condition of system of cooling about clarification of the reasons of an overheat of the engine (see. Head Routine maintenance, Diagnostics of malfunctions).

Measuring instrument of the current fuel consumption

During movement the measuring instrument constantly fixes the current fuel consumption in km l/100. In modes of idling and compulsory idling of the shooter of a measuring instrument falls to 0.

Movement at very low temperatures of external air, in an intense city cycle (a mode start feet), and also towage of the trailer and movement in the mountain district are connected with the increased fuel consumption.

Index of pressure of impellent oil

At working temperature pressure of oil decreases on single turns. It has not an adverse effect on operational reliability of the engine. Squeezing of a pedal of gas should lead to increase of pressure of impellent oil.

Speedometer

The speedometer is built in in the central part of a combination of devices and shows speed of movement of the car. As a unit of measure km/h serve.

Allocated red sectors of ranges of 30 and 50 km/h serve for tracking of the moments of switching of RKPP on the next transfer.

Tachometer

The tachometer is to the right of a speedometer and shows frequency of rotation of a cranked shaft of the engine in thousand revolutions per minute (the indication of an arrow 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 cranked shaft (the arrow of a tachometer never should come into a red zone of a scale).

For the purpose of protection of the engine at achievement by turns of a cranked shaft of a range of red marking the otsechka of supply of fuel is carried out.

Hours

The dial of onboard hours is built in in the right corner of a combination of devices. The regulator of installation of indications of hours is located at the left under the tachometer dial. Rotation of the regulator extended from the panel clockwise leads to increase in indications, against - to reduction.

Display of indications of the odometer/counter of the current run/indicator of term of approach planned THAT

The display of indications of the odometer, the counter of the current run and the indicator of term of approach planned THAT is built in in the speedometer dial. Dumping of indications of the counter flowing run/switching of modes of the display of the odometer / indicator planned THAT is made by means of the speedometer of the push-button switch located at the left under the dial.

Counter of a distance in kilometers of the current run

The counter registers the current run of the car from the moment of the last dumping of the indications (in kilometers or miles, depending on execution option). Indications of the counter are deduced in the top field of the speedometer of the digital indicator built in in the dial. For dumping of indications of the counter it is necessary to activate a combination of devices, then to press the button of dumping and to hold it pressed during about 1 second.

Odometer

The odometer fixes the general run of the car in kilometers from the moment of the operation beginning. Indications of the odometer are deduced in the bottom field of the speedometer of the digital indicator built in in the dial.

The indicator of term of approach planned THAT (the active system - Assyst)

See also Section Identification numbers of the car of Head Routine maintenance

The indicator of term of approach planned informs THAT on OPTIMUM term of carrying out maintenance and its indication are not connected in any way with level of impellent oil.

If the storage battery is disconnected, time of parking of the car does not join in counting of term of approach planned THAT, - for preservation of periodicity of carrying out procedures of routine maintenance this period of time should be considered.


Information on terms of approach planned THAT is deduced in the field of indications of the odometer of the speedometer of the digital display built in in the dial

1 — the Button of switching of the display in an odometer mode


Approximately in one month before term next THAT at the included ignition in the field of indications of the odometer of the digital display of a speedometer is deduced value of size of the remained run, or time (in days) till performance of procedures of the next service.
Thus, the indication 1000 means that planned THAT should be passed through 1000 km, and 10 - in 10 days. The output format of data is defined by car service conditions.

Display switching in a mode of the odometer occurs automatically in 10 seconds, or by pressing the button (1).

At delay of term of carrying out THAT the indicator starts to work in a flashing mode, besides, ahead of figures the minus sign is highlighted.

Possibility of a conclusion of service indications manually for what it is necessary to activate previously a combination of devices is provided also, and then twice within 1 second to press the button (1). Display switching in an odometer mode occurs as before automatically in 10 seconds, or by pressing the same button.

Indication of term of approach planned THAT is automatically switched off through 10 with or dies away by button (1) pressing.
Dumping of the indicator is made at Mercedes-Benz car repair shop where planned THAT was carried out.

In case of need dumping of the indicator can be made by own strengths of the owner of the car:
  • Turn a key in the ignition lock in situation 2 and at once twice within 1 second press the button (1).
  • The last indication of term of approach planned THAT is displayed in the counter of the general passable way.
    Key in the lock of a shaft of a steering wheel turn in situation 0 approximately within 10 seconds.
  • Press the button (1) and hold the pressed.
  • Key in the lock of ignition turn in situation 2.
  • The button (1) continue to hold pressed, on the screen of the display there will be highlighted an indication of old term of the previous service, then, approximately in 10 seconds after a sound signal term next THAT will be deduced, - release the button (1).
  • At casual dumping of indication of term of approach planned THAT function can be again activated on HUNDRED Mercedes-Benzs.
  • The size of the run remaining before performance next THAT, is defined by a manner of driving and lies in limits from 15000 to 22500 km (365 ÷ 730 days). An economic manner of driving at average turns of the engine and refusal of trips on short distances promote its increase.
  • The schedule of routine maintenance of the car is presented in Head Routine maintenance.

    Precautionary control lamp of antiprobuksovochny (ASR) and protivozanosny (ESP) of systems

    This control lamp is quickly activated at inclusion of ignition and should go out right after implementation of start of the engine. Activation of this control lamp accompanies compulsory shutdown of antiprobuksovochny (ASR) and protivozanosny (ESP) of systems (see. Sections of Antiprobuksovochnaya system (ASR) and Electronic protivozanosny system (ESP)). Lamp activation in a flashing mode during 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 lower speed to safe level.

    Light indicator of activation 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 and differs a characteristic dark blue luminescence.

    Control lamp of a charge of the storage battery

    The control lamp of a charge should light up at inclusion of ignition and die away right after engine start. Inclusion of this 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 passes a category mode. 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 start can lead to the final category of the battery. Check a condition and effort a tension of a driving belt of the generator, in case of need make the corresponding adjustment. If as it should be, the car it is necessary to drive away a belt at once on the next car repair shop for carrying out diagnostics of refusal and performance of necessary regenerative repair.

    Control lamp of level of liquid in the tank of liquid of washing wind glasses/lenses of headlights

    This control lamp is quickly activated at inclusion of ignition and should go out right after implementation of start of the engine. Activation of a control lamp during movement testifies that level of washing liquid fell approximately to 1/4 volumes of the corresponding tank.

    Control lamp of level of cooling liquid

    This control lamp is quickly activated at inclusion of ignition and should go out right after implementation of start of the engine. Activation of a control lamp during movement testifies that level of cooling liquid in a broad tank fell to a dangerous limit and it is necessary to make the corresponding adjustment urgently.

    Control lamp of pressure of impellent oil

    The control lamp of pressure of impellent oil (red) should light up at inclusion of ignition and die away right after engine start. 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 failure of filament lamps of external lighting devices

    This control lamp is quickly activated in a mode of a weak luminescence at inclusion of ignition and should go out right after implementation of start of the engine. Lamp activation in a mode of a bright luminescence (both at ignition key turn in situation 2, and during movement) testifies to failure of the filament lamp of one of external lighting/alarm devices.

    At failure of a lamp of a stoplight the control lamp will be activated only during braking.

    Any lighting devices of an additional complete set should be connected through a safety lock established in front of the control block of filament lamps. Negligence to performance of this condition is fraught with failure of a control lamp, lighting devices and the control block.


    EPC

    Control lamp of failures of the electronic monitoring system of injection of the diesel engine

    Activation of this control lamp at the idle engine warns the driver about violation of serviceability of functioning of a control system by supply of fuel. The capacity developed by the engine in a similar situation can decrease considerably and the car should be driven away on the closest car repair shop of the Mercedes-Benz company.

    Control lamp of refusals of system of adjustment of a road gleam (model with automatic dempfiruyushchy system - ADS)

    The control lamp is quickly activated in a mode of a weak luminescence at inclusion of ignition and should go out right after implementation of start of the engine. Refusal of a lamp of shutdown, and also its activation during movement testifies to violation of serviceability of functioning by the automatic dempfiruyushchy system operating rigidity of shock-absorbers of a suspension bracket of the car depending on a condition of the road, loading and a driving manner. The car should be driven away at the first possibility on HUNDRED companies Mercedes-Benzs.

    At shutdown of an onboard food in a consequence of a detachment or a discharge of the storage battery the control lamp will burn the working engine. For shutdown of a lamp turn a steering wheel from an emphasis against the stop.


    BAS
    ASR

    Control lamp of failures of the amplifier of emergency braking (BAS) / antiprobuksovochny system (ASR)

    The control lamp is quickly activated at inclusion of ignition and should go out right after implementation of start of the engine. Refusal of a lamp of shutdown, and also its activation during movement testifies to violation of serviceability of functioning of BAS or ASR system.

    At BAS system refusal the brake system of the car continues to function in the usual (not strengthened) mode.

    Malfunction of ASR system can lead to appreciable decrease in capacity developed by the engine. The car should be driven away immediately on HUNDRED companies Mercedes-Benzs for carrying out diagnostics and performance of necessary regenerative repair.


    BAS
    ESP

    Control lamp of failures of the amplifier of emergency braking (BAS) / protivozanosny system (ESP)

    The control lamp is quickly activated at inclusion of ignition and should go out right after implementation of start of the engine. Refusal of a lamp of shutdown, and also its activation during movement testifies to violation of serviceability of functioning of BAS or ESP system.

    At BAS system refusal the brake system of the car continues to function in the usual (not strengthened) mode. Remark: Malfunction of ESP system can lead to appreciable decrease in capacity developed by the engine. The car should be driven away immediately on HUNDRED companies Mercedes-Benzs for carrying out diagnostics and performance of necessary regenerative repair.


    Control lamp of refusals of ABS

    This control lamp serves for control of serviceability of functioning of ABS, quickly works at inclusion of ignition and should die away some seconds later after implementation of start of the engine.

    Control lamp of wear of brake shoes

    The control lamp is quickly activated at inclusion of ignition and should go out right after implementation of start of the engine. Lamp activation during braking testifies to wear of frictional overlays of brake shoes to limiting admissible value and need of performance of their urgent replacement.

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

    The control lamp (red) 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 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 joins in movement time, it usually testifies to excessive falling of level of brake liquid. 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.

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

    SRS

    Control lamp of refusals of elements of system of additional safety (SRS)

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

    The alarm indicator «Fasten a seat belt»

    This indicator has an amber luminescence and quickly works ignition inclusion. Transition of the indicator to a flashing mode after implementation of start of the engine is urged to remind drivers/passengers of need of a pristegivaniye seat belts.

    Control lamp of preheat of the diesel engine

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

    Light indicators of indexes of turn

    Light indicators 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 display arrows coincides with the chosen direction of a change of course of the car. Indicators work in a flashing mode with the frequency corresponding to frequency of a blinking of indexes of turn. The speeded-up blinking of one of indicators usually testifies to a peregoraniye of a lamp of one of indexes of the corresponding turn. It is necessary to make replacement of the burned-down lamp at the first possibility not to create emergencies on roads.

    The simultaneous blinking of indicators of indexes of both turns usually accompanies turning on of the alarm system.
