The combination of instruments, meters, warning lights and indicator lights
The design of the instrument cluster Device combination The design of the instrument cluster is shown in the illustration. Test and Measurement Activation of the instrument cluster Activation of the instrument cluster is performed when the door is opened by clicking on one of embedded in the combination of the right and left of the speedometer instrument switch, and when the ignition / open the driver's door. Disabling the board automatically. Adjusting the intensity of illumination of devices Adjusting the intensity of illumination of devices (with the navigation lights - see. Section Controls and the salon equipment) is made by means mounted in the instrument panel to the left under the dial speedometer tilt-and-push knob - using the same handle can be made by activating a combination of devices (see. above) and the switching operation of the built-in digital speedometer display / reset the counter current mileage (See below.). Combination meter fuel reserve / coolant temperature The meter is in the left corner of the instrument cluster and is equipped with two pointers, one of which (right) registers the amount of fuel remaining in the tank, the second (left) is used to indicate the temperature of the engine coolant. In the lower part of the dial gauge mounted display shows the outdoor temperature readings. Fuel gauge stock The error of the meter readings supply of fuel is minimal when the car occupies strictly horizontal position. When driving on winding or hilly roads the device error increases. The functioning of the meter does not depend on the position of the ignition key. The label corresponds to 1/1 of the full-fill, 0 - tank empty. Built-in dial gauge indicator lamp with the image of a gas column informs the driver of the need as soon as possible to make refueling a vehicle. Coolant temperature gauge Under normal conditions, the boiling point of the coolant (antifreeze added thereto with corrosion inhibitor), calculated on the tucked into operation at a pressure path of about 130 ?� C. In severe operating conditions, such as very hot weather or after prolonged uphill arrow pointer can go up to the top of the red mark on the scale. If the engine temperature is increased so that the arrow pointer comes within the red range of the meter, you should immediately stop moving, pull over, park and make an inspection of the cooling system in order to ascertain the causes of engine overheating (see chap. Power supply system and exhaust) . Outside temperature display Display Indication ambient air temperature sensor is built into the dial left combo meter dash. The temperature is determined in degrees Celsius (?� C).
Changing the display after leaving the garage comes with a certain delay due to the adaptation of the sensor.
Also, the delay provided with forced increase the display in accordance with an increase in ambient temperature while engine coolant temperature above 60 ?� C - which can prevent crosstalk from hot engine during stops and when the vehicle is moving at low speeds. Speedometer The speedometer is mounted in the center of the instrument cluster and indicates the vehicle speed in km / h. LCD odometer / mileage counter current / motor oil level indicator / Maturity planned TO LCD odometer, mileage counter current and planned LED TO Maturity built into the speedometer dial. Resetting the counter current run / switching display is performed by using the left hand side under the dial of the speedometer button switch (see ibid.). The odometer and odometer current path The odometer records the total mileage of the vehicle from the time it is put into operation, resets the counter allows you to track the current mileage since the last reset of his testimony (in kilometers). Switching the odometer / counter is made by means of a speedometer to the left of the button.
To reset the counter, activate the instrument cluster (see. Above), then press the reset button and hold it down for about 1 second. Motor oil level indicator When checking the oil level of the motor vehicle must be in a horizontal position. The readings should be done after about 5 minutes after the warm up to normal operating temperature of the engine.
Turn the key in the ignition lock to position 2 and wait for the display on the screen  , Then twice for 1 second to press the push button (5). The display must be highlighted the following:
 (the oil level is normal)
 (pour 1 liter of oil)
 (pour 1.5 liters of oil)
 (pour 2 liters of oil)
or  (pump out the excess oil to prevent engine damage or failure of the catalytic converter).
If the correct level measurement is not possible, the indication flashes - repeat the test after a short time. Maturity indicator scheduled maintenance (MOT system-Assyst) See. Section active warning system Maturity planned TO (ASSYST). Tachometer The right of the tachometer and speedometer shows the frequency of engine speed in thousands of revolutions per minute (indication of an arrow should be multiplied by 100). To avoid engine damage Never exceed the maximum engine speed (tachometer needle should never go into the red zone of the scale).  | In order to protect the engine when the crankshaft speed range red markings made cut-off the fuel supply. |
Clock Dial on-board clock is built into the face of the tachometer. Regulator setting the clock is placed to the left under the tachometer dial (ibid.). Rotation of the elongated panel knob clockwise increases the testimony against - to decrease. Warning lights and indicator lights The assembly dash car built a whole complex of warning lights and indicators, with which the driver receives important information about serviceability / malfunction of the main components and systems of the car. Arrangement of warning lights on the instrument panel is shown in the illustration. The following provides information about the principle of operation of each of the available LEDs individually.

| Warning traction control lamp (ETS) and protivozanosnoy (ESP) systems |
This warning lamp is activated briefly when the ignition and should go out immediately after the engine starts. Activation of the warning lamp is accompanied by the forced shutdown protivozanosnoy (ESP) system (see. Sections Traction System (4-ETS) and electronic protivozanosnaya system (ESP)). Activation lamps in flashing mode while driving the car warns the driver that the wheels of the car are at the limit of adhesion to the road surface and the speed should be reduced to a safe level.  | When towing the car with torn from the ground the rear wheels, as well as checking of serviceability of functioning of brakes on the stand the motor must be stopped, because otherwise the active inhibitory effect of the ESP system can result in failure of the rear brakes! |
| The indicator lamp failure brake assist system (BAS) / protivozanosnoy system (ESP) |
The warning lamp is activated briefly when the ignition and should go out immediately after the engine starts. Refusal of a lamp of the trip, as well as its activation during movement testifies to infringement of serviceability of functioning of the BAS system or ESP. | When refusing the BAS system braking systems continue to operate in the normal (non-enhanced) mode.
Faulty ESP system can lead to a marked reduction in the power developed by the engine. The car should be immediately driven away on STO company Mercedes-Benz for the diagnosis and perform the necessary regenerative repair. |
To turn off triggered when the engine is running after turning off the warning lamp catering, turn the steering wheel from lock to lock. When the voltage level drops below 10 V there is an automatic system shutdown BAS. Accompanied by a triggering of the warning lamp. Return the system to a working condition also occurs automatically when the recovery voltage level - lamp should go. | The indicator lamp Traction Control System (4-ETS) |
The warning lamp is activated briefly when the ignition and should go out immediately after the engine starts. Refusal of a lamp of the trip, as well as its activation during movement testifies to infringement of serviceability of functioning of the system 4-ETS, - the car should immediately drive away in the workshop of the company Mercedes-Benz for the diagnosis and perform the necessary regenerative repair. | At high load on the brakes automatically short-term shutdown of the system 4-ETS in order to prevent overheating of the brakes - this trip is accompanied by the activation of a control lamp.
The system 4-ETS is activated at speeds between 40 and 80 km / h when it reaches any of the wheels limit tire grip (eg, single-sided black ice). Proper wheel is braked at the same time to ensure reliable traction. |
| Control lamp ABS anti-lock braking system |
This indicator light is used to monitor the correct functioning of the ABS, briefly activated when the ignition switch and extinguished after a few seconds after the engine starts. Refusal of a lamp of the trip, as well as its activation during movement testifies to infringement of serviceability of functioning ABS, - the car should immediately drive away in the workshop of the company Mercedes-Benz for the diagnosis and perform the necessary regenerative repair. | Simultaneously with ABS disabled and the system 4-ETS, BAS and ESP), which should be supported by appropriate actuation of warning lights (see. Above). |
| Control lamp of brake pad wear |
The warning lamp is activated briefly when the ignition and should go out immediately after the engine starts. Activation of the lamp during braking can indicate deterioration of the friction brake linings to the limit values and the need to perform urgent replacement. | Control lamp of level of impellent oil |
Control lamp of level of impellent oil briefly when the ignition is activated and extinguished after the engine starts. Activation of warning lamp with the engine running indicates a dangerous lowering of the motor oil. At the first opportunity, check the oil level, if necessary, make appropriate adjustment (see chap. Power supply system and exhaust system), make sure there are no signs of leaks. | Control lamp of level / coolant temperature |
This warning lamp is activated briefly when the ignition and should go out immediately after the engine starts. Activating a control lamp during movement testifies to the fact that the coolant level in the expansion tank down to a dangerous limit, and an urgent need to make the appropriate adjustments, or the coolant temperature has reached the upper limit of the acceptable range (129 ?� C). Stop the engine, let it cool a little, check the fluid level in the expansion tank, if necessary, make appropriate adjustment (see chap. Power supply system and exhaust). | The warning lamp mode off-road |
This indicator lamp to confirm the serviceability of switching to off-road (see. Section Controls and interior equipment) - in the process of switching the lamp should blink three times and then switch to a constant glow. Rapid flashing lights when the ignition is a malfunction in the system switch to LOW RANGE and the car should be driven away on HUNDRED company Mercedes-Benz for the diagnosis and perform the necessary regenerative repair. | The control lamp of refusals MIL () |
This indicator will light briefly when the ignition is activated and extinguished after a few seconds after the engine starts. Refusal of a lamp of the trip, as well as its activation during movement testifies to infringement of serviceability of functioning of the engine management / emission control, - car must be immediately driven away on STO company Mercedes-Benz for the diagnosis and perform the necessary regenerative repair. | To turn off the warning lamp, activated after refilling the fuel tank is completely exhausted should be three or four times to repeat the procedure starting. |
| The warning lamp off the front passenger airbag when installing the child seat in the right front seat (AIRBAG OFF) |
This indicator lamp should light up when fixing such a special child seat on the front passenger seat, thus confirming the fact disable the passenger airbag. Disclaimer operation control lamp indicates that the airbag deactivation switch did not happen and the child seat should be moved back - ask for help from the service station Mercedes-Benz. | The indicator light activation of the fog lamp |
Actuation of the indicator light is confirmed serviceability of activation fog lights (both front and rear - see. Section Controls and interior equipment). | Control lamp lock locking mechanism of adjustment of the steering column |
Activation of the control lamp warns the driver that the mechanism for adjusting the height of the steering column is not locked (see. Section Controls and the salon equipment) and start driving dangerous. | The control lamp of additional safety (SRS) |
This indicator lamp for about 4 seconds lights up when the ignition switch and extinguished immediately after the engine starts. When Lama stays on with the engine running (constant or flashing mode), this indicates a malfunction of components SRS. At a corresponding complete control of the operation of the lamp may be an indication of a fault in the contours of the side and head airbags or automatic emergency devices pretensioners. | Control lamp of brake fluid level / failure of electronic brake force distribution (EBV) / charging the parking brake indicator |
The warning lamp illuminates at raising the parking brake, reminding the driver to release it before the move. Movement with the cocked lay brake leads to rapid overheating and failure of the brakes on the rear wheels, as well as premature wear of the tire tread of the rear wheels, and in addition, may be an infringement of serviceability of functioning of the anti-lock braking (ABS).
If the warning light stays on after the parking brake is released or turned on while driving, it usually indicates an excessive fall in the level of brake fluid, - one of the possible causes of the gradual decrease in the brake fluid level is normal wear and tear of the friction brake linings.
Another reason for the activation of the warning lamp is a violation of serviceability of functioning of the electronic brake force distribution (EBV), - the car should be driven away to the nearest service station for evaluation of pads and leak testing of a hydraulic path of brake system. | Short-term operation of a control lamp occurs also when the ignition (even when the parking brake is released). |
| The warning lamp battery charge |
Charge indicator lamp should light up when the ignition is switched on and off immediately after the engine starts. Activation of the lamp with the engine running warns the driver of infringement of serviceability of functioning of the charge when the battery goes into the discharge. It should be immediately shut down all electricity consumers, on the functioning of which does not depend on traffic safety and to try to avoid stopping the engine, as an attempt to run it can lead to the final discharge of the battery. Check the condition and force the generator drive belt tension, if necessary, make appropriate adjustment. If the belt is okay, the car should immediately drive off to the nearest service station for diagnostics of failure and performance of necessary regenerative repair. | The indicator light activation beam |
This indicator is used to confirm the activation of main beam. | The control lamp of preheat of the diesel engine |
The control lamp of preheat lights up when the ignition is switched and indicates the activation of system of preheat. Starting must take place no earlier than the control lamp turns off. | Control lamp of electronic power control system of the diesel engine (EPC) |
This indicator lamp should light up when the ignition is switched on and off immediately after the engine starts. Operation of the lamp while driving indicates a failure in the fuel injection diesel engine - the system enters the emergency mode of operation, in which the motion should not be the way to squeeze the gas pedal and exceed the crankshaft revolutions per minute in 2500. Developed by the engine power in a similar situation can be significantly reduced and the car should be driven away on the nearest car repair shop of Mercedes-Benz. | Indicator light "Fasten seat belt" |
This indicator is an amber glow and a short (about 6 seconds) the ignition is activated, reminding the driver and passengers to fasten the seat belts. | Control lamp of level / frost fluid in the reservoir fluid windscreen washer / headlamp lenses |
This warning lamp is activated briefly when the ignition and should go out immediately after the engine starts. Activation control lamp during movement indicates that the washing liquid level has fallen to approximately 1/4 of the volume of the corresponding container.
At temperatures below 0 ?� C, this warning lamp can also warn the driver of the washer fluid freezing and the need to increase the concentration in it frost ingredient. Indicator lights turn indicators Indicator lights in the form of arrows are green and are used to control the proper functioning of the direction indicators. Direction indicator arrows coincides with the selected direction of the exchange rate of the vehicle. Indicators work in flashing mode with a frequency corresponding to the frequency of flashing turn indicators. Rapid blinking an indicator usually indicates a blown bulb of one of the indicators of the corresponding rotation. It should be as soon as possible to replace the burnt-out bulb, so as not to accidents on the roads.
Simultaneous flashing signs both turns usually accompanied by the inclusion of an alarm.
