53 Getting started
Driving
Release the parking brake by pulling on
release handle1.
The indicator lamp; (USA only)
or3 (Canada only) in the clock
goes out.
Driving
Depress the brake pedal.
Move gear selector lever to
positionDorR.
Release the brake pedal.
Carefully depress the accelerator
pedal.
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.
iWait for the gear selection process to com-
plete before setting the vehicle in motion.
!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 (
page 52).
iAt vehicle speeds of approximately 9 mph
(15 km/h), the automatic central locking system
engages and the locking knobs drop down.
The automatic door lock feature can be deacti-
vated (
page 164).
You can open a locked door from the inside.
Open door only when conditions are safe to do
so.
!Simultaneously depressing the accelerator
pedal and applying the brake reduces 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.
!Place the gear selector lever in positionR
orP 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 engine
speeds may shorten the service life of the
engine.
CLK 63 AMG:
At low engine temperatures below +68°F
(+20°C), the engine’s maximum speed is
restricted in order to protect it from damage.
Avoid driving your vehicle at full speed when the
engine is cold to prevent premature engine wear
and/or diminished comfort.

71 Safety and Security
Occupant safety
Occupant Classification System
The O
ccupant Classification System (OCS)
automatically turns the front passenger
front air bag on or off based on the classi-
fied occupant weight category determined
by weight sensor readings from the front
passenger seat.
Occupants must sit properly belted in a po-
sition that is as upright as possible with
their back against the seat backrest and
feet on the floor to be correctly classified.
If the occupant's weight is transferred to
another object in the vehicle (e.g. by
leaning on armrests), the OCS may not be
able to properly approximate the
occupant’s weight category. Both driver and the front passenger should
always use the 56 indicator lamp
as an indication of whether or not the front
passenger is properly positioned.
iThe system does not deactivate the
head-thorax air bag and the emergency tension-
ing device.
iIf your seat, including your trim cover and
cushion needs to be serviced in any way, take
the vehicle to an authorized Mercedes-Benz
Center.
Only seat accessories approved by
Mercedes-Benz may be used. Warning!G
If the 56 indicator lamp illuminates
when an adult or someone larger than a
small individual is in the front passenger
seat, have the front passenger re-position
himself or herself in the seat until the
56 indicator lamp goes out.
More information about air bag display
messages (
page 382).
In the event of a collision, the air bag control
unit will not allow front passenger front air
bag deployment when the OCS classified
the front passenger seat occupant as being
up to or less than the weight of a typical
12-month-old child in a standard child
restraint or if the front passenger seat is
sensed as being empty.
When the OCS senses that the front passen-
ger seat occupant is classified as being up
to or less than the weight of a typical
12-month-old child in a standard child
restraint, the 56 indicator lamp will
illuminate when the engine is started and

appears in the multifunction display and
the audio system is muted. When the
connection is established, the message
Call connected appears in the multifunc-
tion display. All information relevant to the
emergency, such as the location of the
vehicle (determined by the GPS satellite
location system), vehicle model, identifica-
tion number and color are generated.A voice connection between the Response
Center and the occupants of the vehicle
will be established automatically soon af-
ter the emergency call has been initiated.
The Response Center will attempt to
determine more precisely the nature of the
emergency provided they can speak to an
occupant of the vehicle.
The Tele Aid system is available if:

it has been activated and is
operational. Activation requires a
subscription for monitoring services,
connection and cellular air time

the relevant cellular phone network

If the indicator lamps in the SOS button, in
the Roadside Assistance button and/or in
the Information button remain illuminated
constantly in red and/or message

above, the system may not operate as
expected. Have the system checked at the
nearest Mercedes-Benz Center as soon as
possible.
iLocation of the vehicle on a map is only pos-
sible if the vehicle is able to receive signals from
the GPS satellite network and pass the informa-
tion on to the Response Center.
