Warning!
G
When leaving the vehicle, always remove the
SmartKey from the starter switch and lock
the vehicle. Do not leave children unattend-
ed in the vehicle, or with access to an un-
locked vehicle. Unsupervised use of vehicle
equipment may cause an accident and/or
serious personal injury.iVehicles with automatic transmission:

32 Getting startedAdjusting
AdjustingSeats
The seats can be adjusted either manually
or electrically, depending on the vehicle’s
equipment.Warning!
G
All seat, head restraint, steering wheel, and
rear view mirror adjustments, as well as fas-
tening of seat belts, must be done before
the vehicle is put into motion.Warning!
G
Do not adjust the driver’s seat while driving.
Adjusting the seat while driving could cause
the driver to lose control of the vehicle.
Never ride in a moving vehicle with the seat
back reclined. Sitting in an excessively re-
clined position can be dangerous. You could
slide under the seat belt in a collision. If you
slide under it, the belt would apply force at
the abdomen or neck. That could cause
serious or fatal injuries. The seat back and
seat belts provide the best restraint when
the wearer is in an upright position and belts
are properly positioned on the body. Your
seat must be adjusted so that you can cor-
rectly fasten your seat belt (
page 40).
Never place hands under the seat or near
any moving parts while a seat is being ad-
justed.
Warning!
G
When leaving the vehicle, always remove the
key from the starter switch, and lock your
vehicle.
The power seats* can also be operated with
the driver’s or front passenger door open.
Do not leave children unattended in the ve-
hicle, or with access to an unlocked vehicle.
Unsupervised use of vehicle equipment may
cause an accident and/or serious personal
injury.
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 passenger side front
airbag when it is properly installed. Other-
wise they will be struck by the airbag when
it inflates 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.
