30 Getting startedUnlocking
The “Getting started” section provides an
overview of the vehicle’s most basic func-
tions. First-time Mercedes-Benz owners
should pay special attention to the infor-
mation given here.
If you are already familiar with the basic
functions described here, the “Controls in
detail” section will provide you with further
information. The corresponding page
references are located at the end of each
segment.

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 up-
right position and belts are properly posi-
tioned on the body. Your seat must be
adjusted so that you can correctly 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
SmartKey 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
TM1

compatible child seat, which operates with
the BabySmart
TM system installed in the ve-
hicle to deactivate the passenger front 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.

Steering wheel
Warning!
G
For your protection, drive only with properly
positioned head restraints.
Adjust head restraint so that the head
restraint supports the back of the head at
eye level. This will reduce the potential for
injury to the head and neck in the event of
an accident or similar situation.
Do not drive the vehicle without the seat
head restraints. Head restraints are
intended to help reduce injuries during an
accident.
Warning!
G
Do not adjust the steering wheel while
driving. Adjusting the steering wheel while
driving, or driving without the adjustment
locked could cause the driver to lose control
of the vehicle.
When leaving the vehicle, always remove the
SmartKey from the starter switch and lock
your vehicle.
The electrical steering wheel adjustment
feature* can also be operated with the
driver’s door open. Do not leave children
unattended in the vehicle, or with access to
an unlocked vehicle. Unsupervised use of
vehicle equipment may cause an accident
and/or serious personal injury.
