Do not depress accelerator.

Turn the SmartKey in the starter switch
to position3 (
page 34) and release it
again immediately (“touch-start”).
The engine then starts automatically.

Depress the brake pedal.
The gear selector lever lock is released.
For information on turning off the engine
with the SmartKey, see (
page 56).Starting with KEYLESS-GO*
You can start your vehicle without the
SmartKey in the starter switch using the
KEYLESS-GO start/stop button on the
gear selector lever.
The SmartKey with KEYLESS-GO must be
located in the vehicle.

Make sure the gear selector lever is set
toP.

Do not depress accelerator.

Depress the brake pedal during the
starting procedure.
The gear selector lever lock is released.

Press KEYLESS-GO start/stop button
once.
The engine starts automatically if the
SmartKey with KEYLESS-GO is in the
vehicle.
For information on turning off the engine
with KEYLESS-GO, see “Turning off the en-
gine with KEYLESS-GO*” (
page 57).Starting difficulties
If the engine does not start as described,
carry out the following steps:

If you are starting the engine with the
SmartKey, turn SmartKey in starter
switch to position0 and repeat starting
procedure.

If you are starting the engine with
KEYLESS-GO*: Close any doors that
may be open to allow for better detec-
tion of the SmartKey with
KEYLESS-GO*.
Or:
Start the engine with the SmartKey as
radio signals from another source may
be interfering with the SmartKey with
KEYLESS-GO*.

Repeat the starting procedure
(page 46).
Remember that extended starting at-
tempts can drain the battery.

Get a jump start (
page 430).
If the engine does not start after several
starting attempts, there could be a mal-
function in the engine electronics or in the
fuel supply system.

Notify an authorized Mercedes-Benz
Center.

Release the brake pedal.

Carefully depress the accelerator
pedal.
Once the vehicle is in motion, the auto-
matic central locking system engages and
the locking knobs drop down.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.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, which could result in an acci-
dent and/or serious personal injury.
iYou can open a locked door from the
inside. Open door only when conditions
are safe to do so.
You can deactivate the automatic
locking using the control system
(page 155).
!If you hear a warning signal and the
message

display when driving off, you have for-
gotten to release the parking brake.
Release the parking brake.

iWait for the gear selection process to
complete before setting the vehicle in
motion.Warning!
G
It is dangerous to shift the gear selector
lever out ofPorN 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 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.!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.

Automatic transmission
Automatic transmission
For more information on driving with an
automatic transmission, see “Automatic
transmission” (
page 47).
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 167) with
gear ranges (page 166)


the selected program mode:
(C/S) (
page 169)
or
(M/C/S) (CLK 55 AMG only)
(
page 173)


the position of the accelerator pedal
(page 170)


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.

CLK 500:
Cruise control brakes automatically so that
the set speed is not exceeded. The brake
pedal is depressed automatically to do this.
Keep in mind that cruise control is a conve-
nience system designed to assist the driver
during vehicle operation. The driver is and
must always remain responsible for the ve-
hicle’s speed and for safe brake operation.
Keep driver’s foot area clear at all times, in-
cluding the area under the brake pedal. Ob-
jects stored in this area may impair pedal
movement which could interfere with the
braking ability of the cruise control system.
Do not place your foot under the brake pedal
- your foot could become caught.

The segments in the multifunction dis-
play (page 256) go out, and an
acoustic warning sounds.
!Moving gear selector lever to
positionN while driving also cancels
cruise control. However, the gear se-
lector lever should not be moved to
positionN while driving except to coast
when the vehicle is in danger of skid-
ding (e.g. on icy roads).
iDepressing the accelerator pedal does
not deactivate cruise control. After
brief acceleration (e.g. for passing),
cruise control will resume the last
speed set.
iCLK 320/CLK 55 AMG
When you use the cruise control lever
to decelerate, the transmission will
automatically downshift if the engine’s
braking power does not brake the
vehicle sufficiently.
CLK 500:
When you use the cruise control lever
to decelerate, the brake system will
automatically brake the vehicle if the
engine’s braking power does not brake
the vehicle sufficiently.

differences arising from returning to the pre-
