With a smooth motion, pull the seat
belt from seat belt housing1.
Place the shoulder portion of the seat
belt across the top of your shoulder
and the lap portion across your hips.
Push latch plate2 into buckle3 until

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
restrained 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 seat belt would apply force at
the abdomen or neck. That could cause
serious or even fatal injuries. The seat back-
rest and seat belt provide the best restraint
when the wearer is in a position that is as
upright as possible and the seat belt is prop-
erly positioned on the body.
Warning!G
Read and observe the additional warning no-
tices in the “Safety and Security” section
(
page 79).

Proper use of seat belts
Do not twist the seat belt when fasten-
ing.
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 seat 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 position
that is as upright as possible.
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 restraints, toddler restraints or
children in booster seats, always follow
the child seat manufacturer’s instruc-
tions.
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 seat belts over sharp edges.
They could tear.
Do not allow the seat belt to get caught in
the door or in the seat adjustment
mechanism. This could damage the
seat belt.
Never attempt to make modifications to
seat belts. This could impair the effective-
ness of the seat 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 seat belts that were
highly stressed in an accident must be
replaced. Contact an authorized
Mercedes-Benz Center.

56 Getting started
Driving
Driving off
Depress the brake pedal.
Place the gear selector lever in
positionD orR.
Release the brake pedal.
Carefully depress the accelerator
pedal.After a cold start, the transmission en-
gages at a higher revolution. This allows
the catalytic converter to reach its operat-
ing temperature earlier.
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
vehicle control. Your vehicle’s ABS will not
prevent this type of loss of control.
!In order to avoid damage to the
transmission:
Wait for the gear selection process to com-
plete before setting the vehicle in motion.
Place the gear selector lever in positionP
orR only when the vehicle is stopped.
!If you hear a warning signal and the
message
Release Parking Brake appears in
the multifunction display when driving off, you
have forgotten to release the parking brake.
Release the parking brake (
page 55).
iOnce the vehicle is in motion, the automatic
central locking system engages and the locking
knobs drop down.
You can deactivate the automatic locking using
the control system (
page 166).
You can open a locked door from the inside.
Open door only when conditions are safe to do
so.
!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 brakes reduces engine
performance and causes premature brake and
drivetrain wear.

higher wiper speed
have the windshield wipers checked at the
nearest authorized Mercedes-Benz Center
!Do not leave windshield wipers on an inter-
mittent setting when the vehicle is taken to an
automatic car wash or during windshield clean-
ing. Windshield wipers will operate in the pres-
ence 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 wind-
shield. You should therefore switch off the wind-
shield wipers when weather conditions are dry.
iIntermittent wiping is interrupted when the
vehicle is at a standstill and a 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 positionDorR
or
the wiper setting is changed using the
combination switch
