54 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 53).
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 166).
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 brakes 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
positionRorP 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 en-
gine.
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.
60 Getting started
Parking and locking
When the engine is running, the
warning lamp;(USA only)
or3(Canada only) in the clock will
be illuminated.
Switching off headlamps
Turn the exterior lamp switch toM
(
page 129).
Turning off the engine
Place the gear selector lever in
positionP.
Apply the parking brake (page 59).Turning off the engine with the
SmartKey
Turn the SmartKey in the starter switch
to position0 (
page 38).
Remove the SmartKey from the starter
switch.
The immobilizer is activated.
Turning off the engine with
KEYLESS-GO*
Press the KEYLESS-GO start/stop but-
ton to shut off the engine.
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 38).
Warning!G
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. Children could release the
parking brake and/or move the gear selec-
tor lever from positionP, either of which
could result in an accident and/or serious
personal injury.
PositionP alone may not prevent your vehi-
cle from moving, possibly hitting people or
objects. Always set the parking brake in ad-
dition to shifting to positionP (
page 174).
When parked on an incline, always turn the
front wheels towards the road curb.
Getting out of your vehicle without taking
the above measurements to secure it is
dangerous.
iAlways set the parking brake in addition to
shifting to positionP.
On slopes, turn the front wheels towards the
curb.
iThe SmartKey can only be removed from the
starter switch with the gear selector lever in
positionP.

Close the trunk (page 112).
Pull the mechanical key out of the
SmartKey (
page 427).
Insert the mechanical key in the trunk
lid lock.
Turn the mechanical key clockwise to
position2 and remove the mechanical
key in that position to lock the trunk.
The trunk remains locked even when the
vehicle is centrally unlocked.
Insert the mechanical key in the trunk
lid lock.
Turn the mechanical key counterclock-
wise to neutral position1 and remove
the mechanical key in that position to
unlock the trunk.
You can now open the trunk
(
page 110).
Automatic central locking
The doors and the trunk automatically lock
when the ignition is switched on and the
wheels are turning at vehicle speeds of
approximately 9 mph (15 km/h) or more.
You can open a locked door from the
inside. Open doors only when conditions
are safe to do so.
You can deactivate the automatic locking
mode using the control system, see “Set-
ting automatic locking” (
page 166).
iTo deny any unauthorized person access to
the trunk, e.g. when you valet park the vehicle,
lock it separately with the mechanical key. Leave
only the SmartKey or SmartKey with
KEYLESS-GO* less its mechanical key with the
vehicle.
iYou can only cancel the separate trunk lock-
ing mode by means of the mechanical key.
iThe doors unlock automatically after an ac-
cident if the force of the impact exceeds a preset
threshold.
To prevent the vehicle door locks from locking,
deactivate the automatic central locking when
the vehicle
is pushed or towed
is on a test stand

display is inoperative.
As a result, you will not be able to see infor-
mation about your driving conditions, such
as speed or outside temperature, warn-
ing/indicator lamps, malfunction/warning
messages or the failure of any systems.
Driving characteristics may be impaired.
If you must continue to drive, please do so
with added caution. Visit an authorized
Mercedes-Benz Center as soon as possible.
iThe instrument cluster illumination is
dimmed or brightened automatically to suit am-
bient light conditions.
The instrument cluster illumination will also be
adjusted automatically when you switch on the
vehicle’s exterior lamps.
140 Controls in detail
Instrument cluster
Tachometer
The red marking on the tachometer
(
page 28) denotes excessive engine
speed.
To help protect the engine, the fuel supply
is interrupted if the engine is operated
within the red marking.
Clock
In vehicles with Audio 20, the clock can be
set via the control system (
page 160).
Outside temperature indicator
The outside temperature is indicated in the
multifunction display (
page 141).The outside temperature sensor is located
in the front bumper area. Due to its loca-
tion, the sensor can be affected by road or
engine heat during idling or slow driving.
This means that the accuracy of the dis-
played temperature can only be verified by
comparison to a thermometer placed next
to the sensor, not by comparison to exter-
nal displays (e.g. bank signs etc.).
When moving the vehicle into colder ambi-
ent temperatures (e.g. when leaving your
garage), you will notice a delay before the
lower temperature is displayed.
A delay also occurs when ambient temper-
atures rise. This prevents inaccurate tem-
perature indications caused by heat
radiated from the engine during idling or
slow driving.
!Avoid driving at excessive engine speeds, as
it may result in serious engine damage that is not
covered by the Mercedes-Benz Limited
Warranty.
iVehicles with COMAND*:
For information on setting the time in COMAND,
refer to the separate COMAND operating
instructions.
Warning!G
The outside temperature indicator is not de-
signed to serve as an ice-warning device and
is therefore unsuitable for that purpose.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
194 Controls in detail
