Warning!G
A driver’s attention to the road must always
be his/her primary focus when driving. For
your safety and the safety of others, we
recommend that you pull over to a safe
location and stop before placing or taking a
telephone call. If you choose to use the
telephone while driving, please use the
hands-free device and only use the tele-
phone when weather, road and traffic
conditions permit.
Some jurisdictions prohibit the driver from
using a cellular telephone while driving a
vehicle.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet
(approximately 14 m) every second.
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna)
from inside the vehicle while the engine is
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system,
possibly resulting in an accident and /or
personal injury.

171 Controls in detail
Automatic transmission
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.
Shifting procedure
The automatic transmission selects indi-
vidual gears automatically, depending on:

gear selector lever positionD
(
page 172) with gear ranges
(
page 175)

the selected program mode:
(C/S)(
page 176)
or
(M/C/S) (CLK 63 AMG only)
(
page 181)

the position of the accelerator pedal
(
page 174)

the vehicle speedWhen the gear selector lever is in drive
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 of park positionP or neutral
positionN 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 a n d w h e n y o u r r i g h t
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 park positionP only
when the vehicle is stopped.
Avoid spinning of a drive wheel when driving off
on slippery road surfaces. This may cause seri-
ous damage to the drivetrain which is not cov-
ered by the Mercedes-Benz Limited Warranty.

Automatic transmission
Effect
ëNeutral
No power is transmitted from the
engine to the drive axle. When
the brakes are released, the
vehicle can be moved freely
(pushed or towed).
To avoid damage to the trans-
mission, never engage neutral
positionN while driving.
If the ESP
® is deactivated or
malfunctioning:
Move gear selector lever to neu-
tral positionN only if the vehicle
is in danger of skidding, e.g. on
icy roads.
êDrive
The transmission shifts
automatically. All forward gears
are available.
!Coasting the vehicle, or driving for any other
reason with gear selector lever in neutral
positionN can result in transmission damage
that is not covered by the Mercedes-Benz
Limited Warranty.
Warning!G
PositionP alone is not intended to or capa-
ble of preventing your vehicle from moving,
possibly hitting people or objects. Always
set the parking brake in addition to shifting
to park positionP (
page 52).
When parked on an incline, turn the front
wheels towards the road curb.
Do not park this vehicle in areas where com-
bustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.
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 move the
gear selector lever from park positionP,
which could result in an accident and/or
serious personal injury.
Getting out of your vehicle without taking
the above measurements to secure it is
dangerous.

Driving tips
Accelerator position
Your driving style influences the
transmission’s shifting behavior:
Less throttle Earlier upshifting
More throttle Later upshifting
Kickdown
Use kickdown when you want maximum
acceleration.
Press the accelerator past the point of
resistance.
Depending on the engine speed the
transmission shifts into a lower gear.
Ease on the accelerator when you have
reached the desired speed.
The transmission shifts up again.Stopping
When you stop briefly, e.g. at traffic lights:
Leave the transmission in gear.
Hold the vehicle with the brake.
When you stop for a longer period of time
with the engine idling and/or on a hill:
Set the parking brake.
Move the gear selector lever to park
positionP.Maneuvering
When you maneuver in tight areas,
e.g. when pulling into a parking space:
Control the vehicle speed by gradually
releasing the brakes.
Accelerate gently.
Never abruptly step on the accelerator.
Working on the vehicle
Warning!G
When working on the vehicle, set the
parking brake and move gear selector lever
to park positionP. Otherwise the vehicle
could roll away.

page 176), you can select a gear
range for the automatic transmission to
operate within.

You can limit the gear range by pressing
the gear selector lever to the left (D-), and
reverse the gear range limit by pressing
the gear selector lever to the right (D+).

Automatic transmission
Press program mode selector switch
repeatedly until the letter of the
desired program mode appears in the
multifunction display.
SelectCfor comfort driving
(CLK 63 AMG: for standard driving):

The vehicle starts out in second
gear (both forward and reverse) for
gentler starts. This does not apply if
full throttle is applied or gear
range1 is selected.

Traction and driving stability are
improved on icy roads.

Upshifts occur earlier even when
you give more gas. The engine then
operates at lower rpms and the
wheels are less likely to spin.
SelectSfor standard driving
(CLK 63 AMG: for sporty driving):

The vehicle starts out in first gear.

Upshifts occur later.Gear selector lever one-touch
gearshifting
With the gear selector lever in drive posi-
tion D and driving in program modeC orS,
you can limit or extend the gear range.
If your vehicle is equipped with manual
shift programM, you can use the gear
selector lever to manually shift the gears.
The following instructions describe opera-
tion of the gear selector lever when driving
in the automatic program modeC orS.Limiting gear range
Briefly press the gear selector lever to
the left in theD-direction.
The transmission will shift to the next
lower gear as permitted by the shift
program. This action simultaneously
limits the gear range of the transmis-
sion (
page 175).
iFor information on using the gear selector
lever in program modeM, see “Manual shift pro-
gram CLK 63 AMG” (
page 181).
!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 park positionP only
when the vehicle is stopped.
Avoid spinning of a drive wheel when driving off
on slippery road surfaces. This may cause seri-
ous damage to the drivetrain which is not cov-
ered by the Mercedes-Benz Limited Warranty.
Warning!G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced
vehicle control. Your vehicle’s ABS will not
prevent this type of loss of control.
iTo avoid overrevving the engine when down-
shifting, the transmission will not shift to a lower
gear if the engine’s max. speed would be
exceeded.
