Prior to operating the vehicle, the driver should check
and adjust if necessary the seat height, seat position
fore and aft, and backrest angle to insure adequate
control, reach and comfort. The head restraint should
also be adjusted for proper height. See also airbag
section for proper seat positioning.
In addition, also adjust the steering wheel to ensure
ad eq uate con tr ol, r each, operation and com fort. B ot h the
inside and outside rear view mirrors should be adjusted
for adequate rearward vision.
Fasten seat belts. Infants and small children should be
seated in a properly secured restraint system that
complies with U.S. Federal Motor Vehicle Safety
Standard 213 and Canadian Motor Vehicle Safety
Standard 213.

Wa r n i n 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 vehicle to deactivate the passenger
side front airbag when it is properly installed.
Otherwise they will be struck by the airbag when it
inflates in a crash. If this happens, serious or fatal
injury can result.
According to accident statistics, children are safer
when properly restrained in the rear seating
positions than in the front seating 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, fully in accordance with the
child seat manufacturer’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.

(Vehicle with enlarged cargo area)
The total load weight including vehicle occupants and
luggage/cargo should not exceed the vehicle capacity
weight indicated on the certification tag which can be
found on the left door pillar.The handling characteristics of a fully loaded vehicle
depend greatly on the load distribution. It is therefore
recommended to load the vehicle according to the
illustrations shown, with the heaviest items being
placed towards the front of the vehicle.
Always place items being carried against front or rear
seat backrests, and fasten them as securely as possible.
The heaviest portion of the cargo should always be kept
as low as possible since it influences the handling
characteristics of the vehicle.
Note:
The trunk is the preferred place to carry objects.
The enlarged cargo area should only be used for items
which do not fit in the trunk alone.
