Rear seat head restraints Important safety notes G WARNING For safety reasons, always drive with the rear head restraints in the upright position when the rear seats are occupied. Keep the area around head restraints clear of articles (e.g. clothing) to not obstruct the folding operation of the head restraints. G WARNING For your protection, drive only with properly positioned head restraints. Adjust the head restraint in such a way that it is as close to the head as possible and the center of the head restraint supports the back of the head at eye level. This will reduce the potential for injury to the head and neck in the event of an accident or similar situation. With a rear seat occupied, make sure to move the respective head restraint up from the lowest non-use position and have the occupant adjust the head restraint properly.

Useful information

i This Operator's Manual describes all models and all standard and optional equipment of your vehicle available at the time of publication of the Operator's Manual. Country-specific differences are possible. Please note that your vehicle may not be equipped with all features described. This also applies to safety- related systems and functions.

i Read the information on qualified specialist workshops: (Y page 27).

Exterior lighting Important safety notes For reasons of safety, Mercedes-Benz recommends that you drive with the lights switched on even during the daytime. In some countries, operation of the headlamps varies due to legal requirements and self-imposed obligations.

Driving abroad Conversion to symmetrical low beam Switch the headlamps to symmetrical low beam in countries in which traffic drives on the opposite side of the road from the country where the vehicle is registered. This prevents glare to oncoming traffic. When using symmetrical lights, the edge of the road is not lit as widely and as far ahead as normal. Have the headlamps converted at a qualified specialist workshop as close to the border as possible before driving in these countries.

Conversion to asymmetrical low beam after returning Have the headlamps converted back to asymmetrical low-beam headlamps at a qualified specialist workshop as soon as possible after crossing the border again.

Setting the exterior lighting Setting options Exterior lighting can be set using the: Rlight switch Rcombination switch (Y page 125) Rthe on-board computer (Y page 276)

Hazard warning lamps

X Turn the light switch to L or Ã. X Press the combination switch beyond the

pressure point in the direction of arrow :. In the à position, the high-beam headlamps are only switched on when it is dark and the engine is running. The blue K indicator lamp in the instrument cluster lights up when the high- beam headlamps are switched on.

X To switch off the high-beam

headlamps: move the combination switch back to its normal position. The blue K indicator lamp in the instrument cluster goes out.

i Vehicles with Adaptive Highbeam Assist: when Adaptive Highbeam Assist is active, it controls activation of the high-beam headlamps (Y page 127).

X To switch on the hazard warning lamps:

press button :. All turn signals flash. If you now switch on a turn signal using the combination switch, only the turn signal lamp on the corresponding side of the vehicle will flash.

X To switch off the hazard warning

lamps: press button :.

The hazard warning lamps automatically switch on if: Ran air bag is deployed. Rthe vehicle decelerates rapidly from a

speed of more than 45mph (70 km/h) and comes to a standstill.

The hazard warning lamps switch off automatically if the vehicle reaches a speed of over 6mph (10km/h) again after a full brake application. i The hazard warning lamps still operate if

the ignition is switched off.

Headlamp cleaning system The headlamps are cleaned automatically if the "Wipe with washer fluid" function is operated five times (Y page 134) while the lights are on and the engine is running. When you switch off the ignition, the automatic headlamp cleaning system is reset and counting is resumed from 0.

Active light function

Cornering light function

The cornering light function improves the illumination of the road over a wide angle in the direction you are turning, enabling better visibility in tight bends, for example. It can only be activated when the low-beam headlamps are switched on. Active: Rif you are driving at speeds below

25mph (40 km/h) and switch on the turn signal or turn the steering wheel

Rif you are driving at speeds between

25mph (40 km/h) and45mph (70 km/h) and turn the steering wheel

Not active: if your speed exceeds 25mph (40 km/h) or if you switch off the turn signal or turn the steering wheel to the straight-ahead position. The cornering light function may remain lit for a short time, but is automatically switched off after no more than three minutes.

The active light function is a system that moves the headlamps according to the steering movements of the front wheels. In this way, relevant areas remain illuminated while driving. This allows you to recognize pedestrians, cyclists and animals. Active: when the lights are switched on.

Adaptive Highbeam Assist Important safety notes G WARNING The Adaptive Highbeam Assist is only an aid intended to support you while driving. The driver is and remains responsible for proper vehicle lighting in accordance with the prevailing light, sight and traffic conditions.

128 Exterior lighting

The system may be impaired or unavailable when Rvisibility is poor, e.g. due to snow, rain, fog,

or heavy spray

Rthe optical sensor area of the windshield is dirty, fogged up, or covered by a sticker for example

The system cannot recognize the following road users: RRoad users without a lighting system of

their own, e.g. pedestrians

RRoad users with dim lighting of their own,

e.g. cyclists

RRoad users whose lighting is obstructed,

e.g. road users behind a guardrail

RIn some seldom cases, even road users with

a lighting system of their own may be recognized too late or not at all.

The automatic high-beam headlamps will then not be deactivated or it will be activated in spite of preceding or oncoming road users. This could endanger you and/or others and cause an accident. Always pay close attention to the traffic situation and switch off the high beam manually if necessary.

You can use this function to set the headlamps to change between low beam and high beam automatically. The system recognizes vehicles with their lights on, either

approaching from the opposite direction or traveling in front of your vehicle, and consequently switches the headlamps from high beam to low beam. The system automatically adapts the low- beam headlamp range depending on the distance to the other vehicle. Once the system no longer detects any other vehicles, it reactivates the high-beam headlamps. The system's optical sensor is located behind the windshield near the overhead control panel.

Switching Adaptive Highbeam Assist on/off

: High-beam headlamps ; Turn signal, right = High-beam flasher ? Turn signal, left X To activate: activate the Adaptive

Highbeam Assist function using the on- board computer (Y page 277). X Turn the light switch to Ã. X Press the combination switch beyond the

pressure point in the direction of arrow : (Y page 125). The _ indicator lamp in the multifunction display lights up if it is dark and the light sensor activates the low-beam headlamps. If you are driving at speeds above approximately 28 mph (45km/h):

the headlamp range is set automatically depending on the distance between the vehicle and other road users. If you are driving at speeds above approximately 35 mph (55km/h) and no other road users have been detected: the high-beam headlamps are switched on automatically. The K indicator lamp in the instrument cluster also lights up. If you are driving at speeds below approximately 30 mph (45km/h) or other road users have been detected or the roads are adequately lit: the high-beam headlamps are switched off automatically. The K indicator lamp in the instrument cluster goes out. The _ indicator lamp in the multifunction display remains lit.

X To deactivate: move the combination

switch back to its normal position. The _ indicator lamp in the instrument cluster goes out.

Headlamps fogged up on the inside The headlamps may fog up on the inside if there is high atmospheric humidity. X Switch on the lights and drive off. The level of moisture diminishes, depending on the length of the journey and the weather conditions (humidity and temperature).

If the level of moisture does not diminish: X Have the headlamps checked at a qualified

specialist workshop.
