Warning!
G
Children 12 years old and under must never
ride in this vehicle, 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.
Infants and small children must be seated in
an appropriate infant or child restraint sys-
tem, which is properly secured with the ve-
hicle’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 be-
hind the seats. Otherwise you could
damage the seats.
The memory function (
page 114) lets
you store the setting for the seat posi-
tion together with the settings for the
steering wheel and the rear view mir-
rors.

Fastening the seat belts
Warning!
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 maneu-
vers, 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 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 passenger should al-
ways 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 provide the
protection they were designed to afford if
the occupants are using their seat belts
(page 58).

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 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 with at least one window
fully open.
iYou can also use the “touch-start”
function. Turn the SmartKey to
position3 and release it again immedi-
ately. The engine then starts automati-
cally.

For information on turning off the engine
with KEYLESS-GO, see “Turning off with
KEYLESS-GO*” (
page 54).
Starting difficulties
If the engine does not start as described,
carry out the following steps:
If you are starting the engine with the
SmartKey: Turn SmartKey in starter
switch to position0 and repeat starting
procedure.
If you are starting the engine with
KEYLESS-GO*: Close any doors that
may be open to allow for better detec-
tion of the SmartKey with
KEYLESS-GO.
Or:
Start the engine with the SmartKey as
radio signals from another source may
be interfering with the SmartKey with
KEYLESS-GO*.
Repeat the starting procedure
(page 43). Remember that extended
starting attempts can drain the battery.
Get a jump start (
page 363).
If the engine does not start after several
starting attempts, there could be a mal-
function in the engine electronics or in the
fuel supply system.
Notify an authorized Mercedes-Benz
Center.

Warning!
G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take the
SmartKey with KEYLESS-GO* with you and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. Children could release the
parking brake, which could result in an acci-
dent and/or serious injury.
Warning!
G
It is dangerous to shift the gear selector le-
ver out ofP orN if the engine speed is high-
er than idle speed. If your foot is not firmly
on the brake pedal, the vehicle could accel-
erate 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.!In order to avoid damage to the trans-
mission:
Wait for the gear selection process
to complete before setting the vehi-
cle in motion.
Place the gear selector lever in
positionR only when the vehicle is
stopped.
46 Getting startedDrivingOnce the vehicle is in motion, the automat-
ic central locking system engages and the
locking knobs drop down.
After a cold start, the transmission engag-
es at a higher revolution. This allows the
catalytic converter to reach its operating
temperature earlier.

!If you hear a warning signal when driv-
ing off, you have forgotten to release
the parking brake.
Release the parking brake.!Do not run cold engine at high engine
speed. Running a cold engine at high
engine speed may shorten the service
life of the engine.
!Simultaneously depressing the acceler-
ator pedal and applying the brake re-
duces engine performance and causes
premature brake and drivetrain wear.iYou can open a locked door from the
inside. Open door only when conditions
are safe to do so.
You can deactivate the automatic lock-
ing using the control system
(page 146).

the SmartKey is removed.Warning!
G
With the engine not running, there is no
power assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the ve-
hicle.
Warning!
G
Do not park this vehicle in areas where com-
bustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system, as these materials could be
