Folding bench seat in the cargo compartment (Wagon) Important safety notes G WARNING The rear seat backrests must be locked in the upright position if you are using the folding bench seat in the cargo compartment. Do not pull away unless the head restraint in the folding bench seat is installed correctly. Make sure that the center of the head restraint supports the seat occupant's head at about eye level. This can reduce the risk of injury to a child in the event of an accident. Ensure that the seat belt is routed correctly across the body and the seat belt buckle is engaged. Never leave children unsupervised in the vehicle. This applies even if they are secured in a child restraint system. Secure children as recommended; see the "Children in the vehicle" section.
G WARNING Only replace damaged covers with genuine covers. Make sure that items of luggage and other objects in the cargo compartment are well secured. Otherwise, the load could cause injury in the event of sharp braking, a sudden change in direction or an accident.
The folding bench seat in the cargo compartment is only suitable for persons no more than 4.6 ft (1.40 m) tall and weighing a maximum of 110 lb (50 kg). The maximum permissible weight available for passengers may be reduced by extensive optional extras and the vehicle load. Observe the maximum gross vehicle weight and the gross axle weight rating, which can be found on the vehicle identification plate (Y page 405). The combined cargo cover and net must be installed if you are using the folding bench seat (Y page 297).
Folding out the folding bench seat

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.

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. If you wish to drive during the daytime without lights, switch off the daytime running lamps function in the on-board computer (Y page 239).
Driving abroad Symmetrical low-beam headlamps 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.
Asymmetrical low-beam headlamps Have the headlamps converted back to asymmetrical low-beam headlamps at a qualified specialist workshop as soon as possible after crossing the border again.

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: if you are driving at speeds below 25 mph (40 km/h) and switch on the turn signals or turn the steering wheel. Not active: if you are driving at speeds above 25 mph (40 km/h) or switch off the turn signals 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.
Active light function
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. 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.
