30 Getting startedUnlockingThe “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 provide you with further
information. The corresponding page refer-
ences are located at the end of each seg-
ment.

Key in the starter switch.
For more information, see “Locking and

32 Getting startedAdjusting
AdjustingSeats
The seats can be adjusted either manually
or electrically, depending on the vehicle’s
equipment.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 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 serious or fatal injuries.
The seat back and seat belts provide the
best restraint when the wearer is in an up-
right position and belts are properly posi-
tioned on the body. Your seat must be
adjusted so that you can correctly fasten
your seat belt (
page 41).
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 and lock
your vehicle.
The power seats* can also be operated with
the driver’s or passenger door open. Do not
leave children unattended in the vehicle, or
with access to an unlocked vehicle. Unsu-
pervised 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 the front seat, 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 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.
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 back seats and be seated in an
appropriate infant or child restraint system,
which is properly secured with the vehicle’s
seat belt and top tether strap, or secured via
lower anchors and top tether strap, fully in
accordance with the child seat manufactur-
er’s instructions.

Getting started
Driving
After a cold start, the automatic transmis-
sion shifts at a higher engine revolution.
This allows the catalytic converter to reach
its operating temperature earlier.
For more information on driving, see “Driv-
ing instructions” (
page 223).
iYou can open a locked door from the
inside. Open doors only when condi-
tions are safe to do so.
You can deactivate the automatic lock-
ing using the control system
(page 129).
!If you hear a warning signal when driv-
ing off, you have forgotten to release
the parking brake.
Release the parking brake.!Simultaneously depressing the acceler-
ator pedal and applying the brake re-
duces engine performance and causes
premature brake and drivetrain wear.
iVehicles with automatic transmission:
Wait for the gear selection process to
complete before setting the vehicle in
motion.Warning!
G
Vehicles with automatic transmission: It is
dangerous to shift the gear selector lever
out of
P or N if the engine speed is higher
than idle speed. If your foot is not firmly on
the brake pedal, the vehicle could acceler-
ate 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.!Place the gear selector lever in
position R only when the vehicle is
stopped in order to avoid damaging the
transmission.!Do not run cold engine at high engine
speeds. Running a cold engine at high
speeds may shorten the service life of
the engine.
