Seats
You can find information about enlarging the luggage compartment (folding forward/removing the rear seats) on more.
Depending on the vehicle's equipment, seat adjustments can be made either manually 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 by a seat adjustment movement.
|
| 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 as you adjust the seat.
Observe the notes concerning the airbag system.
Secure children as recommended; see the "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.
|
 | |
|
The front seats are fitted with active head restraints more. For this reason, it is not possible to remove the head restraints from the front seats.
The rear-compartment head restraints can be removed more.
Please contact a Mercedes-Benz Service Centre for more information.
