30 Getting startedUnlockingThe “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 help you with further in-
formation. The corresponding page refer-
ences are at the end of each segment.

Only vehicles equipped with an
anti-theft alarm system* have
SmartKeys with integrated panic
button*3.

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 41).
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 ve-
hicle.
The power seats* can also be operated with
the driver’s or passenger door open. Do not
leave children unattended in the vehicle, or
with access to an unlocked vehicle. Unsu-
pervised 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.

G
For your protection, drive only with properly

Do not drive the vehicle without the seat
head restraints. Head restraints are intend-
ed to help reduce injuries during an acci-
dent.
Warning!
G
Do not adjust the steering wheel while driv-
ing. Adjusting the steering wheel while driv-
ing, or driving without the adjustment
locked could cause the driver to lose control
of the vehicle.

key from the starter switch and lock your ve-
hicle.
The electrical steering wheel adjustment
feature* can also be operated with the driv-
er’s door open. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. Unsupervised use of vehi-
cle equipment may cause an accident
and/or serious personal injury.

Ensure that the seat belt is always fit-
ted snugly. You should avoid wearing
bulky clothing, such as winter coats,
when traveling in the vehicle.
Starting the engine Manual transmission
Gearshift pattern for manual transmission

Neutral position.

Do not depress accelerator.

Fully depress clutch pedal.

lock.
Warning!
G
Do not pass belts over sharp edges. They
could tear.
Do not allow the belt to get caught in the
door or in the seat adjustment mechanism.
This could damage the belt.
Never attempt to make modifications to
seat belts. This could impair the effective-
ness of the belts.
Damaged seat belts or belts that were highly
stressed in an accident must be replaced by
an authorized Mercedes-Benz Center.
Warning!
G
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide, and inhaling it can cause uncon-
sciousness and lead to death.
Do not run the engine in confined areas
(such as garage) which are not properly ven-
tilated. If you think that exhaust gas fumes
are entering the vehicle while driving, have
the cause determined and corrected imme-
diately. If you must drive under these condi-
tions, drive only with at least one window
fully open.
