Points to remember

For information about folding the rear bench seat forward, see the "Luggage compartment enlargement" section more.

Depending on the vehicle's equipment, the seats can adjusted either manually/electrically or electrically*.

Risk of injury

The seats can still be adjusted when there is no key in the ignition lock. For this reason, children should never be left unsupervised in the vehicle. They could become trapped when adjusting a seat.
Risk of accident

Only adjust the driver's seat when the vehicle is stationary. You will otherwise be distracted from the road and traffic conditions and you could lose control of the vehicle as a result of the seat moving. This could cause an accident.
Risk of injury

Make sure that nobody can become trapped when you adjust the seat.

Observe the notes concerning the airbag system.

Secure children as recommended; see "Children in the vehicle" section.

When you move the seats, make sure that there are no objects in the footwell or behind the seats. Otherwise, you could damage the seats and the objects.

When the rear bench seat is folded forwards, the front seats cannot be moved to their rearmost position. Otherwise, you could damage the seats and the rear bench seat.

Make sure that the sun visor is folded up before setting the backrest angle and head restraint height. Otherwise, the head restraint and sun visor could collide when the head restraint is fully extended.

The rear-compartment head restraints can be removed more.

Please contact a Mercedes-Benz Service Centre for more information.
