Fastening the seat beltWarning!
G
Do not lay any objects in the driver’s foot-
well. Be careful that floor mats or carpets in
the driver’s footwell have sufficient clear-
ance for the pedals.
During sudden driving or braking maneuvers
the objects could get caught between the
pedals. You could then no longer brake or
accelerate.Warning!
G
Always fasten your seat belt before driving
off. Always make sure your passengers are
properly restrained, even those sitting in the
rear and pregnant women.
Failure to wear and properly fasten and po-
sition your seat belt greatly increases your
risk of injuries and their likely severity in an
accident. You and your passengers should
always wear seat belts.
If you are ever in an accident, your injuries
can be considerably more severe without
your seat belt properly buckled. Without
your seat belt buckled, you are much more
likely to hit the interior of the vehicle or be
ejected from it. You can be seriously injured
or killed.
In the same crash, the possibility of injury or
death is lessened if you are wearing your
seat belt. The airbags can only protect as ex-
pected if the occupants are using their seat
belts (
page 56).
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 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.


42 Getting startedDriving
The seat belt presenter for driver and pas-
senger makes it easier to put on the seat
belt.1 Seat belt presenter
Manually adjust the seat belt presenter
to the desired position
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 ride in a moving vehicle with the seat
backrest reclined. Sitting in an excessively
reclined 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 even fatal injuries. The seat
backrest and seat belt provide the best re-
straint when the wearer is in an upright po-
sition and the belt is properly positioned on
the body.
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.Warning!
G
Read and observe the additional warning no-
tices printed in the “Safety and Security”
section (
page 60).
iThe seat belt presenter must be put
back to its original position before lean-
ing the seat backrest toward the rear or
letting someone enter the rear passen-
ger compartment.

right position.


Never use a seat belt for more than one
person at a time.

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.
Contact an authorized Mercedes-Benz Cen-
ter.
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.

Getting started
Driving
After a cold start, the automatic transmis-
sion shifts at a higher engine revolution.
This allows the catalytic converter to reach
its operating temperature earlier.
For more information on driving, see “Driv-
ing instructions” (
page 223).
iYou can open a locked door from the
inside. Open doors only when condi-
tions are safe to do so.
You can deactivate the automatic lock-
ing using the control system
(page 129).
!If you hear a warning signal when driv-
ing off, you have forgotten to release
the parking brake.
Release the parking brake.!Simultaneously depressing the acceler-
ator pedal and applying the brake re-
duces engine performance and causes
premature brake and drivetrain wear.
iVehicles with automatic transmission:
Wait for the gear selection process to
complete before setting the vehicle in
motion.Warning!
G
Vehicles with automatic transmission: It is
dangerous to shift the gear selector lever
out of
P or N if the engine speed is higher
than idle speed. If your foot is not firmly on
the brake pedal, the vehicle could acceler-
ate quickly forward or in reverse. You could
lose control of the vehicle and hit someone
or something. Only shift into gear when the
engine is idling normally and when your right
foot is firmly on the brake pedal.
Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.!Place the gear selector lever in
position R only when the vehicle is
stopped in order to avoid damaging the
transmission.!Do not run cold engine at high engine
speeds. Running a cold engine at high
speeds may shorten the service life of
the engine.

operate in presence of water sprayed
on the windshield, and wipers may be
damaged as a result.
The switch should not be left in inter-
mittent setting as the wipers will wipe
