Switching headlight operating modes and activating turn signals

Switches located on the steering column

Combination switch

Left combination steering column switch (selection of operating modes of external lighting devices, activation of direction indicators).

Using the rotary knob at the end of the steering column switch lever, one of the following operating modes of the exterior lighting devices can be selected:

ABOUT The lights are off

AUTO Automatic selection of the operating mode of lighting devices depending on the lighting conditions.

Activation of parking lights, license plate lights and instrument lighting

Activating low/high beam headlights

Parking lights (the ignition key is turned to position 0 or removed from the ignition switch). The switch lever is lowered to position (4), - the left parking light is activated, (3) - the right.

The headlights are switched from low beam to high beam by pushing the steering column switch lever away from you - the corresponding blue indicator lamp should light up automatically on the instrument panel (see above). To turn off the high beam, return the lever to its original position.

It is also possible to signal with high beams: signaling is carried out by pulling the steering column switch lever towards you and regardless of the selected position of the handle for selecting the operating mode of the external lighting devices (see above).

Note: High beam signalling remains possible even when the ignition is switched off.

The direction indicators are activated by pressing the left steering column stalk lever in the appropriate direction. The lever is moved up or down, depending on the selected direction of course change.

When the lever is moved to the extreme upper/lower position (until it clicks), the corresponding turn signals will continue to function until the steering wheel is returned to the straight-ahead position (the limit switch will trip), or until the lever is returned to the neutral position.

Note: To briefly turn on the indicators, for example when you intend to change lanes, simply pull the lever up or down slightly.

Controlling the operation of the windshield wipers/washers

Windscreen and headlight lens wipers and washers can only be activated when the ignition is on (key in position 1 or 2). The windshield wiper operating mode is selected by moving the switch lever in the vertical plane:



O Off

---- Interval mode

—— Normal high-speed continuous windshield wiper mode



=== High speed continuous wiper mode

Note: When the vehicle speed exceeds 170 km/h, the intermittent windshield wiper mode automatically switches to continuous mode.

On models equipped with a rain sensor, activation of the interval mode of the windshield wipers results in a single operation of the wipers, followed by automatic selection of the pause duration depending on the intensity of wetting of the glass surface.

The washers are activated by pulling the switch lever towards you; the supply of washer fluid is accompanied by several strokes of the windshield wipers.

Note: When the vehicle comes to a complete stop and one of the front doors is open, the intermittent operation of the windshield wipers is suspended, which prevents moisture from being wiped off by the brushes from getting on the clothes of the driver/passenger entering or leaving the vehicle.

Steering column switch for controlling cruise control/Speedtronic variable speed limiter

The cruise control switch is located on the steering column above the combined steering column switch.

A detailed description of the principles of managing the functioning of the tempostat is given in Section Speed control systems (Tempostat/Speedtronic).

The headlight wiper activation switch is located on the vehicle's instrument panel, to the right of the steering column. Activation of the headlight wipers is only possible in position 2 of the ignition key.

Ignition Switch/Steering Column Lock

The ignition switch is located on the right side of the steering column. The key can occupy one of four fixed positions in the lock:

• 0: Steering column lock
• 1: Auxiliary consumers of electricity (parking position)
• 2: Ignition on/Movement
• 3: Starting the engine

Position 0 - steering column lock

The key can be inserted into or removed from the lock only in this position. When the ignition key is turned from position 0 to position 1, the steering column is unlocked. In addition, on models equipped with an automatic transmission, an additional condition for allowing the start is the mandatory transfer of the selector lever to position "P".

The key can only be removed from the ignition switch after it has been turned to position 0.

Note: On models with automatic transmission, removing the key from the ignition switch is only possible after moving the selector lever to the "P" position.

The steering column lock is activated automatically when you try to turn the steering wheel after removing the key from the ignition switch.



Steering column lock sometimes makes it impossible to turn the key in the ignition. In this situation, you should turn the steering wheel slightly in one direction or another (in order to relieve the load), while simultaneously turning the key in the lock.

Attention! Never remove the key from the ignition switch while driving! This will inevitably lead to the steering column locking and loss of control. Remove the key from the switch only after the car has come to a complete stop!

Note: When the front door is open, it is still possible to operate the electric seat adjustments, steering column, windows and sunroof with the key removed from the ignition switch.

Position 1 - parking

In this position of the ignition key, the operation of auxiliary power consumers is ensured (audio system, cigarette lighter, heater fan, windshield wipers, etc.).

Position 2 - ignition on/movement

The ignition key is kept in this position at all times while the vehicle is moving, as well as when the engine is idling. On diesel models, turning the key to position 2 before starting the engine activates the pre-heating system. At the same time, electrical power is supplied to all systems and additional equipment installed on the vehicle. When the key is turned from position 1 to position 2, some of the indicator lamps located on the instrument panel of the vehicle briefly turn on, confirming that the corresponding control systems are functioning properly (see Section Instrument cluster, gauges and control lamps and indicator lights).

Position 3 - launch

When the key is turned to this position, the starter is engaged. After the engine has started, the key should be released and it will automatically return to position 2.

Hazard warning switch

The hazard warning lights are switched on using a button located on top of the steering column. The switch button is equipped with a standard signal lamp with a pictogram depicting two triangles inscribed in each other.

Turning on the hazard warning lights causes all four direction indicators to come on simultaneously (and their indicator lights on the vehicle's instrument cluster). The alarm is designed to warn other road users about a forced stop of the vehicle and is also used in other dangerous situations provided for by traffic regulations. To turn off the hazard warning, press the switch button again.

Note: The hazard warning lights are activated automatically when any of the airbags are deployed.

LOW RANGE mode switch (for off-road driving)

To turn on the rear fog lights in addition to the fog lights, press the lower part of the key switch - the control LED built into the switch assembly should light up.

When activating the automatic mode of operation of external lighting devices, when starting the engine in addition to the standard running lights (dimensions, number plate light) the rear fog light is also activated.

This switch is also used to set the delay time for turning off the headlights when the doors are closed - the upper part of the button should be held down until the desired delay time is displayed on the instrument cluster display (the rotary knob of the left steering column switch must be turned to the O position).

If none of the vehicle doors are opened after the engine is turned off, or if all the doors are not closed securely after opening, the headlight delay function will be turned off automatically after approximately 1 minute.

Note: Within 10 minutes after the doors are closed, the function can be reactivated by opening any of the doors.

Front seat heating mode switches

Two heated seat mode rocker switches are located at the ends of the lower row of switches on the instrument panel console section and allow activation of two seat heating modes (normal and accelerated), and also turn off the heaters.



The seat heating can only be activated when the engine is running.

Activation of the normal mode is accompanied by the activation of one of the two control LEDs built into the switch. During accelerated heating, both LEDs light up.

The heating is switched off as follows: if one built-in control LED is lit, you should press the upper part of the corresponding switch key, two - the lower part. Automatic switching off of the heating elements occurs according to the timer signal after approximately 20 minutes of continuous operation of the heating elements.

Note: The seat heating is also switched off if the charging system is overloaded or the battery charge level is insufficient - in this situation, one or both control diodes (depending on the selected heating mode) switch to flashing mode. After the overload is removed (disconnection of unnecessary electricity consumers) the seat heating will be activated automatically.

Rear power tilt side window switches

The key switches for the electric rear side windows are located second from the edges of the bottom row of switches on the console section of the instrument panel. Pressing the upper part of the switch opens the corresponding window, and pressing the lower part closes it.

The operating mode switch for interior lamps is placed on the ceiling console next to the control switch for the operation of the electric drive of the upper hatch, behind the control panel is the assembly of the two-piece main interior lamp/the holder of the remote control device for the garage door drive.



Location of the switch for operating modes of interior lights (1) and design of the assembly of the two-section main interior light (arrows).

Activation/deactivation of each section of the main interior light is performed by pressing the corresponding lens. In addition, the lighting is automatically switched on when the doors are unlocked using the remote control of the single lock, as well as when they are opened - closing the doors leads to switching off the light with a certain time delay. Automatic switching off of the interior lighting is performed when the ignition is turned on.

A three-position key switch for the operating modes of the lights allows you to turn on/off the rear interior lights, activate the interior lighting mode when opening the doors, and also completely turn off the interior lighting (neutral position of the switch).

Rear individual lights (reading lamps)

Activation/deactivation of rear individual lamps (reading lamps) is produced by pressing on the lenses of their lampshades. In addition, the lighting is automatically switched on when the doors are opened - closing the doors results in the lamp being switched off with a certain time delay. Automatic switching off of the interior lighting is performed when the ignition is switched on.



The rear individual lamps are mounted in the side sections of the headlining directly behind the central pillars.

Luggage compartment light

The lamp is mounted in the central part of the rear section of the ceiling trim and is equipped with an individual three-position switch, allowing you to select the operating mode of the lamp.

Garage door drive remote control device

The holder for fixing the device is placed under the protective cover in the central part of the two-section main interior light assembly.

General information

The universal transceiver built into the assembly allows you to conveniently combine the functions of up to three individual hand-held remote controls and allows you to control the operation of most actuators operating in the radio frequency range, such as a garage door drive, door lock actuators, security systems, etc. The transceiver is powered by an on-board battery, which eliminates the need for periodic replacement of the battery. The transceiver memory is organized according to the ROM principle, which means that there is no need to re-enter data after disconnecting the battery.

Warning! The built-in universal transceiver is not intended for use with garage door opener actuators that do not have an emergency stop reverser function. These requirements were standardized for actuators manufactured on or after April 1, 1982!

Programming the Universal Transceiver

Note: Once the program code has been entered into the transceiver, the original transmitter should be kept in case reprogramming is required (for example, in the case of purchasing a new car). When selling the vehicle, the transceiver software code must be deleted from the device memory for security reasons. See below for details.

Warning! When entering the program code, the garage door may begin to open or close spontaneously - make sure that there are no people or pets in the doorway! Programming the transceiver must be done with the engine off!

With the ignition off (key in position 1 or 2) press the left button of the transmitter on the roof console of the car and, holding it down, wait until the control LED mounted in the console just above the buttons starts to flash at a frequency of about 1 time per second.

Note: When programming any of the buttons for the first time, as well as when reprogramming after a reset, the LED starts to flash almost immediately; when reprogramming a button that is already in use, the LED only activates after approximately 20 seconds.

Without releasing the left button of the control panel, point the portable remote control from the standard kit towards the actuator, which will be controlled from this button, with the end equipped with the emitter towards the left side of the interior rearview mirror, into which the antenna part of the transceiver is integrated, and, without losing sight of the control LED, press the control button of the portable remote control. Hold the button pressed until the blinking frequency of the control LED doubles, confirming the correctness of the input information.

Note: If the gate actuator is equipped with a code change function (Rolling-Code), then you should synchronize the transceiver with the standard transmitter of the driven device - see the operating instructions for the device.

The remaining two control panel buttons are programmed in a similar manner.

Rules for using a universal transceiver

After entering the appropriate program code, the transceiver can be used to control the corresponding actuator (for example, controlling the operation of a garage door drive)To activate the device, simply press the corresponding button on the transceiver control panel (the key in the car ignition must be turned to position 1 or 2), - during the transmission of the control signal, the light indicator must be triggered.

Note: The emitter operates continuously for 20 seconds when the button is pressed, after which the command transmission process is interrupted and the control LED switches to flashing mode - if necessary, press the control button again.

Diagnosing errors in entering program code

If you are unable to enter information from the hand-held transmitter into the transceiver memory quickly enough, proceed as follows:

• a) Replace the battery of the portable remote control;
• b) Ensure that the portable remote control is correctly oriented when brought to the transceiver (the side with the battery compartment should be on the outside);
• c) Try to hold down the buttons on both devices at the same time firmly enough;
• d) Make sure that the transmitter is no more than 125 mm away from the transceiver when entering information. If the frequency of the indicator light flashes does not increase within 15 seconds, confirming successful entry of the program code, try repeating the procedure, slightly changing the position of the transmitter relative to the transceiver - keep the indicator in sight at all times.

If you are unable to enter the code under any circumstances, please contact your authorized Mercedes-Benz service station for advice.

Universal Transceiver Memory Reset

The device design does not provide for the ability to clear data entered for a separate transceiver button. To delete all entered information, hold down both side buttons on the transceiver control panel simultaneously for about 20 seconds. The buttons can be released as soon as the control LED starts flashing.

Note: It is recommended to clear the universal transmitter memory before selling the vehicle.

Procedure in case of car theft

If the vehicle is stolen, the actuators of all transceiver-driven devices that are not equipped with a code alternation function must be reprogrammed - if necessary, consult with representatives of the relevant manufacturers.

When returning a stolen vehicle, all buttons of the built-in transceiver must be reprogrammed.

Sun visors

Sun visors provide protection for the driver/front passenger's eyes from glare from direct sunlight both from the front and from the sides.



The sun visors have two operating positions - to protect from side rays, release the visor from the lock (arrow) and turn it towards the door glass (driver's visor shown).

On some models, a vanity mirror with a hinged cover may be additionally fitted on the rear side of the sun visor. Opening the vanity mirror cover with the ignition on (key in position 1 or 2) causes the mirror backlight to be activated.



Some models may be equipped with a lighted vanity mirror fitted on the rear of the sun visor, which can be folded down and illuminated.
