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 in the “Safety and Security” section
(page 77).

51 Getting started
Driving
Proper use of seat belts

Do not twist the belt when fastening.


Adjust seat belt so that the shoulder
portion is located as close as possible
to the middle of the shoulder (it should
not touch the neck). Never pass the
shoulder portion of the belt under your
arm.


Position the lap belt as low as possible
on your hips (over hip joint) and not
across the abdomen.


Place the seat backrest in a nearly up-
right position.


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 that it is properly
positioned.


Make sure the seat belt is always fitted
snugly. Take special care of this when
wearing loose clothing.
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.

Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause un-
consciousness 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 with at least one window
fully open.
i
You can also use the “touch-start” function.
Turn the SmartKey to position3 and release it
again immediately. The engine then starts auto-
matically.

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 52). Remember that extended
starting attempts can drain the battery.

Get a jump start (
page 419).
If the engine does not start after several

Warning!
G
When leaving the vehicle, always remove the
SmartKey or the SmartKey with
KEYLESS-GO* 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. Children
could release the parking brake, which
could result in an accident 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.

55 Getting started
Driving

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.
Switching on headlamps
Low beam headlamps
The exterior lamp switch is located on the
dashboard to the left of the steering wheel.Exterior lamp switch1Off
2Low beam headlamps on
Turn the exterior lamp switch to
position B.
The low beam headlamps come on.
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 transmis-
sion:


Wait for the gear selection process to com-
plete before setting the vehicle in motion.


Place the gear selector lever in positionD
orR only when the vehicle is stopped.
!
If you hear a warning signal and the mes-
sage Release parking brake
appears in the
multifunction display when driving 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 accelerator
pedal and applying the brake reduces engine
performance and causes premature brake and
drivetrain wear.
i
You can open a locked door from the inside.
Open door only when conditions are safe to do
so.
You can deactivate the automatic locking using
the control system (
page 162).

IIntermittent wiping
IINormal wiper speed
IIIFast wiper speedIntermittent wiping
The intermittent wiping interval is depen-
dent on the wetness of the windshield.

Turn the combination switch in direc-
tion of arrow 1 to positionI.
After the initial wipe, pauses between
wipes are controlled by the rain sensor.
!
Do not operate the windshield wipers when
the windshield is dry. Dust that accumulates on
a windshield might scratch the glass and/or
damage the wiper blades when wiping occurs on
a dry windshield. If it is necessary to operate the
windshield wipers in dry weather conditions, al-
ways operate the windshield wipers with wind-
shield washer fluid (
page 58).
!
Do not leave windshield wipers in intermit-
tent setting when the vehicle is taken to an auto-
matic car wash or during windshield cleaning.
Windshield wipers will operate in the presence of
water sprayed on the windshield, and windshield
wipers may be damaged as a result.
!
If you have set intermittent wiping, dirt on
the surface of the rain sensor or optical effects
may cause the windshield wipers to wipe in an
undesired fashion. This could then damage the
windshield wiper blades or scratch the windows.
You should therefore switch off the windshield
wipers when weather conditions are dry.


58 Getting startedDrivingSingle wipe
Press the combination switch briefly in
direction of arrow2 to the resistance
point.
The windshield wipers wipe one time
without washer fluid.Wiping with windshield washer fluid

Push the combination switch in direc-
tion of arrow2 past the resistance
point.
The windshield wipers operate with
washer fluid.
For information on filling up the washer
reservoir, see “Windshield washer system
and headlamp cleaning system”
(
page 282).
i
Intermittent wiping is interrupted when the
vehicle is at a standstill and a front door is
opened. This protects persons getting into or out
of the vehicle from being sprayed.
Intermittent wiping will be continued when


all doors are closed and the gear selector
lever is in positionD or R
or


the wiper setting is changed using the com-
bination switch
i
To prevent smears on the windshield, wipe
with windshield washer fluid every now and then
even when it is raining.
!
If anything blocks the windshield wipers
(leaves, snow, etc.), switch them off immediate-
ly.


For safety reasons, stop the vehicle in a safe
location and

remove the SmartKey from the starter
switch
or


turn off the engine by pressing the
KEYLESS-GO* start/stop button and
open the driver’s door (with the driver’s
door open, the starter switch is in posi-
tion 0, same as with the SmartKey re-
moved from the starter switch)
before attempting to remove any blockage.


Remove blockage.


Turn the windshield wipers on again.
If the windshield wipers fail to function at all in
switch positionI,


set the combination switch to the next high-
er wiper speed


have the windshield wipers checked at the
nearest authorized Mercedes-Benz Center
