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 rec-
ommend that you pull over to a safe location
and stop before placing or taking a tele-
phone call. If you choose to use the tele-
phone while driving, please use the
hands-free device and only use the tele-
phone when weather, road and traffic condi-
tions permit.
Some jurisdictions prohibit the driver from
using a cellular telephone while driving a ve-
hicle.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of approximately
44 feet (approximately 13.5 m) every sec-
ond.
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, pos-
sibly resulting in an accident and ⁄or
personal injury.

158 Controls in detailAutomatic transmissionOne-touch gearshifting
Even with an automatic transmission you
can change the gears manually when the
gear selector lever is in positionD.
Downshifting
Briefly press the gear selector lever to
the left in the D–direction.
The transmission will shift from the current
gear to the next lower gear. This action
simultaneously limits the gear range of the
transmission (
page 159).Upshifting

Briefly press the gear selector lever to
the right in the D+direction.
The transmission will shift from the current
gear to the next higher gear as permitted
by the shift program. This action simul-
taneously extends the gear range of the
transmission.Canceling gear range limit

Press and hold the gear selector lever
in the D+direction until D reappears in
the multifunction display.
The transmission will shift from the current
gear range directly to gear rangeD.
Shifting into optimal gear range

Press and hold the gear selector lever
in the D–direction.
The transmission will automatically select
the gear range suited for optimal
acceleration and deceleration. This will
involve shifting down one or more gears.
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
the gear selector lever is moved to
theD–direction, the transmission will
not shift to a lower gear if the engine's
max. speed would be exceeded.

Steering wheel gearshift control (Speedshift) CLK 55 AMG
In the manual shift program mode you can
change the gears manually on the steering
wheel or by using the gear selector lever
(page 158).
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 gear only when
the vehicle is stopped.
!Coasting the vehicle, or driving for any
other reason with gear selector lever
inN can result in transmission damage
that is not covered by the
Mercedes-Benz Limited Warranty.Warning!
G
Getting out of your vehicle with the gear
selector lever not fully engaged in positionP
is dangerous. Also, positionP alone is not
intended to or capable of preventing your
vehicle from moving, possibly hitting people
or objects.
Always set the parking brake in addition to
shifting to positionP (
page 46).
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 gras, 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 from the starter switch, take the
SmartKey with KEYLESS-GO* 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 positionP, which
could result in an accident and/or serious
personal injury.
!Avoid spinning of a drive wheel for an
extended period when driving off on
slippery road surfaces. This may cause
serious damage to the drive train which
is not covered by the Mercedes-Benz
Limited Warranty.

C Comfort For comfort driving

Press the program mode selector
switch 1 repeatedly until the letter of
the desired shift program appears in

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.


The power transmission ratio for
gear selector lever positionR
changes depending on the program
mode selected (SorC).
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.
The transmission shifts into a lower
gear.

Ease on the accelerator when you have
reached the desired speed.
The transmission shifts up again.
!Never change the program mode when
the gear selector lever is out of
positionP. This could result in a
change of driving characteristics for
which you may not be prepared.
