The “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.

consumers) and driving position.
All lamps (except high beam headlamp
indicator lamp and turn signal indicator
lamps unless activated) in the instru-
ment cluster come on. If a lamp in the
instrument cluster fails to come on
when the ignition is switched on, have
it checked and replaced if necessary. If
a lamp in the instrument cluster re-
mains on after starting the engine or
comes on while driving, see “Lamps in
instrument cluster” (page 290).
3Starting position
i
When you switch on ignition, the indi-
cator and warning lamps (except high
beam headlamp indicator lamp and
turn signal indicator lamps unless acti-
vated) in the instrument cluster come
on. The indicator and warning lamps
(except high beam headlamp indicator
lamp and turn signal indicator lamps if
activated) will go out when the engine
is running. This indicates that the re-
spective systems are operational.
i
The SmartKey can only be removed
from the starter switch with the gear
selector lever in positionP.

If the SmartKey cannot be turned, the
battery may not be sufficiently
charged.
Check the battery and charge it if
necessary (
page 353).
Get a jump start (page 356).
To prevent accelerated battery dis-
charge and a possible dead battery, al-
ways remove the SmartKey from the
starter switch when the engine is not in
operation.
Warning!G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. 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.

Adjusting
Adjusting
Seats
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 in an excessively reclined position as
this can be dangerous. You could slide un-
der 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
fatal injuries.
The seat back and seat belts provide the
best restraint when the wearer is in a nearly
upright position and belts are properly posi-
tioned on the body. Your seat must be ad-
justed so that you can correctly fasten your
seat belt (
page 43).
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
SmartKey from the starter switch, take it
with you, and lock the vehicle.
Even with the SmartKey removed from the
starter switch, the power seats can be oper-
ated when the respective door is open.
Therefore, do not leave children unattended
in 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
Children 12 years old and under must never
ride in the front seat, 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
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 the back seats and be seated in
an appropriate infant or child restraint sys-
tem, which is properly secured with the ve-
hicle’s seat belt and top tether strap, or
secured via lower anchors and top tether
strap, fully in accordance with the child seat
manufacturer’s instructions.

For more information, see “Heated steer-
ing wheel” (
page 215).
Warning!G
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
SmartKey from the starter switch, take it
with you, and lock the vehicle.
Even with the SmartKey removed from the
starter switch, the steering wheel adjust-
ment feature can be operated when the driv-
er’s door is open. Therefore, 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.

SmartKey from the starter switch, take it
with you, and lock the vehicle.
Do not leave children unattended in the ve-
hicle, or with access to an unlocked vehicle.
Children could release the parking brake,
which could result in an accident and/or se-
rious personal injury.
Warning!G
It is dangerous to shift the gear selector le-
ver out ofP or N 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.
!
In order to avoid damaging the trans-
mission,
wait for the gear selection process
to complete before setting the vehi-
cle in motion.
place the gear selector lever in
positionPorR only when the vehi-
cle is stopped.
!
If you hear a warning signal when driv-
ing off, you have forgotten to release
the parking brake.
Release the parking brake.

After a cold start, the automatic transmis-
sion shifts at a higher revolution. This al-
lows the catalytic converter to reach its
operating temperature earlier.
For more information, see “Driving instruc-
tions” (
page 220).
For information on off-road driving, see
“Off-road driving” (

You can open the doors from inside.
Open doors only when the conditions
are safe to do so.
You can deactivate the automatic
locking using the control system
(
page 142).
!
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.
