Warning!
G
Children 12 years old and under must never 
ride in the front seat, except in a 
Mercedes-Benz authorized BabySmart
TM 
compatible child seat, which operates with 
the BabySmart
TM system installed in the ve-
hicle to deactivate the front passenger air-
bag when it is properly installed. Otherwise 
they will be struck by the airbag when it in-
flates in a crash. If this happens, serious or 
fatal injury will result.
According to accident statistics, children 
are safer when properly restrained in the 
rear seating positions than in the front seat-
ing positions. Infants and small children 
must ride in back seats and be seated in an 
appropriate infant or child restraint system, 
which is properly secured with the vehicle's 
seat belt and top tether strap, or secured via 
lower anchors and top tether strap, fully in 
accordance with the child seat manufactur-
er’s instructions.
A child’s risk of serious or fatal injuries is 
significantly increased if the child restraints 
are not properly secured in the vehicle and 
the child is not properly secured in the child 
restraint.

positioned head restraints.
Adjust head restraint to support the back of 
the head approximately at ear level.
Do not drive the vehicle without the seat 
head restraints. Head restraints are intend-
ed to help reduce injuries during an acci-
dent.
iThe front passenger seat head restraint 
automatically lowers after a few sec-
onds when the front passenger seat is 
not occupied. This improves the driv-
er’s outward view as well as the for-
ward view from the rear passenger 
compartment.
When the front passenger seat is occu-
pied again, the front passenger seat 
head restraint returns to the last set 
position within a few seconds.
If the front passenger seat was moved 
fore or aft while not being occupied, 
the front passenger seat head restraint 
returns to a position that corresponds 
best with the seat’s axial position when 
the seat is occupied again.

ing. Adjusting the steering wheel while driv-
ing could cause the driver to lose control of 
the vehicle.
