Warning!
G
Children 12 years old and under must never
ride in this vehicle, 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 front
air bag when it is properly installed.
Otherwise they will be struck by the air bag
when it inflates in a crash. If this happens,
serious or fatal injury will result.
Infants and small children must be seated in
an appropriate BabySmart
TM compatible in-
fant or child restraint system, which is prop-
erly 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.
!When moving the seats, make sure
there are no items in the footwell or
behind the seats. Otherwise you could
damage the seats.

Make sure the steering column is se-
curely locked by trying to move the
steering wheel up and down, in and out
before driving off.
Warning!
G
Do not adjust the steering wheel while driv-
ing. Adjusting the steering wheel while driv-
ing, or driving without the steering wheel
adjustment feature locked could cause the
driver to lose control of the vehicle.
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle.
Even with the SmartKey removed from the
starter switch, the electrical steering wheel
adjustment feature* can be operated when
the driver’s door is open. Therefore, 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.
!Do not drive the vehicle until you have
properly locked the steering column.Warning!
G
Only adjust the steering wheel with the vehi-
cle at a standstill and make sure the steer-
ing column is securely locked in place
before driving off.
Driving without the steering column locked
may cause an unexpected steering wheel
movement which could cause the driver to
lose control of the vehicle. Make sure the
steering column is securely locked by trying
to move it up and down, and in and out be-
fore driving off.
48 Getting startedDrivingWarning!
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 front
air bag when it is properly installed.
Otherwise they will be struck by the air bag
when it inflates in a crash. If this happens,
serious or fatal injury will result.
Infants and small children must be seated in
an appropriate BabySmart
TM compatible in-
fant or child restraint system, which is prop-
erly 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.
Warning!
G
Never let more people ride in the vehicle
than there are seat belts available. Be sure
everyone riding in the vehicle is correctly re-
strained with a separate seat belt. Never use
a seat belt for more than one person at a
time.Warning!
G
Never ride in a moving vehicle with the seat
backrest in an excessively reclined position
as this 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 ab-
domen or neck. That could cause serious or
even fatal injuries. The seat backrest and
seat belt provide the best restraint when the
wearer is in a nearly upright position and the
belt is properly positioned on the body.
Warning!
G
Read and observe the additional warning no-
tices printed in the “Safety and Security”
section (
page 68) and (
page 71).
50 Getting startedDriving
Never use a seat belt for more than one
person at a time.
Do not fasten a seat belt around a per-
son and another object at the same
time.
When using a seat belt to secure infant
or toddler restraints or children in
booster seats, always follow the child
seat manufacturer’s instructions.
Check your seat belt during travel to
make sure it is properly positioned.
Make sure the seat belt is always fitted
snugly. Take special care of this when
wearing loose clothing.
Starting the engine
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.
Do not bleach or dye seat belts as this may
severely weaken them. In a crash, they may
not be able to provide adequate protection.
Damaged seat belts or belts that were highly
stressed in an accident must be replaced.
Contact 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 possible death.
Do not run the engine in confined areas
(such as a garage) which are not properly
ventilated. If you think that exhaust gas
fumes are entering the vehicle while driving,
have the cause determined and corrected
immediately. If you must drive under these
conditions, drive only with at least one win-
dow fully open.
