AdjustingSeatsWarning!
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 se-
rious 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 correctly 
fasten your seat belt (
page 37).
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, take the KEY-
LESS-GO
* card (if so equipped) with you, 
and lock your vehicle.
The power seats can also be operated with 
the appropriate door open. Do not leave 
children unattended in the vehicle, or with 
access to an unlocked vehicle. Unsuper-
vised 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 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 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.
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.

Do not adjust the steering wheel while driv-
ing. Adjusting the steering wheel while driv-
ing could cause the driver to lose control of 
the vehicle.
When leaving the vehicle, always remove the 
key from the starter switch, and take the 
KEYLESS-GO
* card (if so equipped) with 
you.
The steering wheel adjustment feature can 
also be operated with the driver’s door

the vehicle, or with access to an unlocked 
vehicle. Unsupervised use of vehicle equip-
ment may cause an accident and/or serious 
personal injury.

Warning!
G
Exercise care when using the passenger 
side exterior rear view mirror. The mirror 
surface is convex (outwardly curved surface 
for a wider field of view). Objects in mirror 
are closer than they appear. Check your in-
side rear view mirror or glance over your 
shoulder before changing lanes. Warning!
G
In case of an accident, liquid electrolyte may 
escape the mirror housing if the mirror glass 
breaks.
Electrolyte has an irritating effect. Do not al-
low the liquid to come into contact with 
eyes, skin, clothing, or respiratory system. 
In case it does, immediately flush the affect-
ed area with water, and seek medical help if 
necessary.
!Electrolyte drops coming into contact 
with the vehicle paint finish can only be 
completely removed while in their liq-
uid state and by applying plenty of wa-
ter.iThe memory function (
page 99) lets 
you store the steering wheel adjust-
ment together with the adjustment for 
the seat and the exterior rear view mir-
rors.
!If an exterior rear view mirror housing 
is forcibly pushed forward or rearward, 
reposition it by applying firm pressure 
until it snaps into place. The mirror 
housing is now properly positioned and 
you can adjust the mirror normally.

42 Getting startedDrivingDriving
Place the gear selector lever in 
positionD orR.
Release the brake pedal.
Carefully depress the accelerator 
pedal.
Once 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.iYou can open a locked door from the 
inside. Open door only when conditions 
are safe to do so.!If you hear a warning signal when driv-
ing off, you have forgotten to release 
the parking brake. 
Release the parking brake.
iWait for the gear selection process to 
complete before setting the vehicle in 
motion.Warning!
G
It is dangerous to shift the selector lever out 
ofP orN if the engine speed is higher than 
idle speed. If your foot is not firmly on the 
brake pedal, the vehicle could accelerate 
quickly forward or in reverse. You could lose 
control of the vehicle and hit someone or 
something. Only shift into gear when the en-
gine is idling normally and when your right 
foot is firmly on the brake pedal.
!Simultaneously depressing the acceler-
ator pedal and applying the brake re-
duces engine performance and causes 
premature brake and drivetrain wear.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.

Step firmly on the parking brake1.
When the engine is running, the indica-
tor lamp 
; 
(USA only) or

(Can-
ada only) in the speedometer dial will 
be illuminated
Warning!
G
Wait until the vehicle is stationary before re-
moving the key from the starter switch. The 
vehicle cannot be steered when the key is 
removed.Warning!
G
With the engine not running, there is no 
power assistance for the steering system. In 
this case, it is important to keep in mind that 
a considerably higher degree of effort is nec-
essary to steer the vehicle.
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 
ignited and cause a vehicle fire.
To reduce the risk of personal injury as a re-
sult of vehicle movement, before
 turning off 
the engine and leaving the vehicle always:
Keep right foot on brake pedal.
Firmly depress parking brake pedal.
Move the selector lever to positionP.
Slowly release brake pedal.
When parked on an incline, turn front 
wheel against road curb.
Turn the key to starter switch position0 
and remove, or press start / stop button 
(vehicles with KEYLESS-GO
*).
Take the key and the KEYLESS-GO
* 
card (vehicles with KEYLESS-GO
*) and 
lock vehicle when leaving.

key from the starter switch, take the KEY-
LESS-GO
* card (if so equipped) with you 
and lock the vehicle. Do not leave children 
unattended in the vehicle, or with access to 
an unlocked vehicle. Children could release 
the parking brake and/or move the gear se-
lector lever from positionP, either of which 
could result in an accident and/or serious 
injury.
Warning!
G
Getting out of your vehicle with the selector 
lever not fully engaged in positionP is dan-
gerous. Also, when parked on an incline, 
positionP alone may not prevent your vehi-
cle from moving, possibly hitting people or 
objects.
Always set the parking brake in addition to 
shifting to positionP (
page 140).
When parked on an incline, also turn front 
wheel against road curb.
iAlways set the parking brake in addi-
tion to shifting to positionP.
On steep slopes, turn the front wheels 
towards the road curb.
