Seats
75Seats
Depending on the vehicle's equipment, seat
adjustments can be made either manually/
electrically or electrically*. G
Risk of injury
The seats can still be adjusted when there
is no key in the ignition lock. For this rea-
son, children should never be left unsuper-
vised in the vehicle. They could become
trapped by a seat adjustment movement. G
Risk of accident
Only adjust the driver's seat when the vehi-
cle is stationary. You will otherwise be dis-
tracted 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. G
Risk of injury
Make sure that nobody can become trap-
ped 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.
i The head restraints in the front seats are
fitted with the NECK-PRO system
(Y page 49). For this reason, it is not pos-
sible to remove the head restraints from
the front seats.
For design reasons, the rear-compartment
head restraints cannot be removed.
Please contact a Mercedes-Benz Service
Centre for more information. Adjusting the seats manually and
