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.
Warning!
G
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 only with at least one win-
dow fully open.

60 Getting startedParking and lockingTurning off engine
Shift the automatic transmission to
positionP (
page 178).
Apply the parking brake (
page 59).
Turning off with the SmartKey
Turn the SmartKey in the starter switch
(page 36) to position0.
Remove the SmartKey from the starter
switch.
The immobilizer is activated.Turning off with KEYLESS-GO*
Press the KEYLESS-GO start/stop
button (
page 37) to turn off the en-
gine.
With the driver's door closed, the start-
er switch is now in position1. With the
driver’s door opened, the starter switch
is set to position0, same as SmartKey
removed from starter switch
(
page 36).
Releasing seat belts
Press the seat belt release button
(page 47).
Allow the retractor to completely
rewind the seat belt by guiding the
latch plate.
iAlways set the parking brake in addi-
tion to shifting to positionP
(page 178).
On slopes, turn the front wheels to-
wards the road curb.
!Make sure the seat belt retracts fully so
that the seat belt and/or latch plate
cannot get caught or pinched in the
door or in the seat mechanism. This
can damage the seat belt and impair
the effectiveness of the seat belt,
and/or cause damage to the door
and/or door trim panel. Such damage
is not covered by the Mercedes-Benz
Limited Warranty.
Damaged seat belts must be replaced.
Contact an authorized Mercedes-Benz

Control system
Control system
The control system is activated as soon as
the SmartKey in the starter switch is
turned to position1 or as soon as the
KEYLESS-GO start/stop button* is in
position1. The control system enables you
to:
call up information about your vehicle
change vehicle settings.
For example, you can use the control sys-
tem to find out when your vehicle is next
due for service, to set the language for
messages in the multifunction display, and
much more.
The control system relays information to
the multifunction display.

For more information on menus displayed
in the multifunction display, see “Menus”
(page 150).
iThe displays for the audio systems (ra-
dio, CD player) will appear in English,
regardless of the language selected.
Warning!
G
A driver’s attention to the road and traffic
conditions must always be his/her primary
focus when driving.
For your safety and the safety of others,
selecting features through the multifunction
steering wheel should only be done by the
driver when traffic and road conditions per-
mit it to be done safely.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximate-
ly 14 m) every second.

176 Controls in detailAutomatic transmissionFor more information on driving with an
automatic transmission see “Automatic
transmission” (
page 49).
Your vehicle’s transmission adapts its gear
shifting process to your individual driving
style by continually adjusting the shift
points up or down. These shift point adjust-
ments are performed based on current
operating and driving conditions.
If the operating conditions change, the
automatic transmission reacts by
adjusting its shift program.
Gearshift pattern for automatic
transmission
The automatic transmission selects indi-
vidual gears automatically, depending on:
the gear selector lever
positionD(
page 178) with
gear ranges (page 181)
the selected program mode:
(C/S)(
page 182)
or
(M/C/S) (CLS 55 AMG only)
(
page 187)
the position of the accelerator pedal
(page 180)
the vehicle speed
iDuring the brief warm-up, transmission
upshifting is delayed. This allows the
catalytic converter to heat up more
quickly to operating temperature.
Warning!
G
Make sure that absolutely no objects are ob-
structing the pedals range of movement.
Keep the driver’s footwell clear of all obsta-
cles. If there are any floormats or carpets in
the footwell, make sure that the pedals still
have sufficient clearance.

Automatic transmission
1Current gear range/gear selector lever
position
2Current program mode
The current gear range/gear selector lever
position and program mode (
C/S) or
(
M/C/S) appear in the multifunction
display.An additional indication of the current gear
selector lever position can be found on the
cover of the shifting-gate.
The indicators come on when you activate
a switch (e.g. unlocking the vehicle or
opening a door) and go out after approxi-
mately 15 minutes.
When the gear selector lever is in
positionD, you can influence transmission
shifting by:
limiting the gear range
changing gears manually
Warning!
G
It is dangerous to shift the gear 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 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.
!Allow engine to warm up under low
load use. Do not place full load on the
engine until the operating temperature
has been reached.
Shift into reverse gearR or parking
positionP only when the vehicle is
stopped.
Avoid spinning of a drive wheel for an
extended period when driving off on
slippery road surfaces. This may cause
serious damage to the drivetrain which
is not covered by the Mercedes-Benz
Limited Warranty.
