Steering wheel gearshift control
one-touch gear shifting CL 55 AMG and CL 65 AMG
The steering wheel gearshift control pro-
vides an alternative method for changing
the gears manually and limiting or extend-
ing the gear range for automatic shifting
with the gear selector lever in positionD
and driving in the automatic program
modeC orS.The steering wheel gearshift buttons are
located to the left and right of the steering
wheel.
1Left button: downshift
2Right button: upshift
iFor information on using the steering
wheel gearshift control in manual
program modeM (CL 55 AMG and
CL 65 AMG only), see “Manual shift
program CL 55 AMG and CL 65 AMG”
(page 175).
iTo avoid overrevving the engine when
downshifting with steering wheel
gearshift buttons, the transmission will
not shift to a lower gear if the engine’s
max. speed would be exceeded.!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 parking
positionP only when the vehicle is
stopped.
Avoid spinning of a drive wheel for an
extended period when driving off on
slippery road surfaces. This may cause
serious damage to the drivetrain which
is not covered by the Mercedes-Benz
Limited Warranty.

174 Controls in detailAutomatic transmissionThe following instructions describe opera-
tion of the steering wheel gearshift control
when driving in the automatic program
modeC orS.
For instructions on operating the steering
wheel gearshift control and gear selector
lever in the manual program modeM, see
“Manual shift program CL 55 AMG and
CL 65 AMG” (
page 175).Downshifting
Briefly press button1 on the left side
of the steering wheel.
The transmission will shift to the next
lower gear as permitted by the shift
program. This action simultaneously limits
the gear range of the transmission
(
page 170) when you are driving in the
automatic program mode (CorS).
Upshifting
Briefly press button2 on the right
side of the steering wheel.The transmission will shift to the next
higher gear as permitted by the shift
program. This action simultaneously
extends the gear range of the transmission
when you are driving in the automatic
program mode (CorS).
Canceling gear range limit
Press and hold button2 on the right
side of the steering wheel until
D
reappears in the tachometer display.
The transmission will shift from the current
gear range directly to gear rangeD.
Shifting into optimal gear range
Press and hold button1 on the left
side of the steering wheel.
The transmission will automatically select
the gear range suited for optimal
acceleration and deceleration. This may
involve shifting down one or more gears.
iYou cannot shift with the steering
wheel gearshift buttons when the gear
selector lever is in positionP,N orR.
The last selected program
mode (CorS) is switched on when the
engine is restarted in the automatic
program mode.
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.

Driving systems
Driving systems
The driving systems of your vehicle are de-
scribed on the following pages:
Cruise control and Distronic*, with
which the vehicle can maintain a preset
speed.
ABC with vehicle level control system,
with which you can change vehicle sus-
pension characteristics.
Parktronic*, which serves as a parking
assistant.
For information on the BAS, ABS, and ESP
®
driving systems, see “Driving safety sys-
tems” (
page 80).
Cruise control
Cruise control automatically maintains the
speed you set for your vehicle.
Use of cruise control is recommended for
driving at a constant speed for extended
periods of time. You can set or resume
cruise control at any speed over 20 mph
(30 km/h).
The cruise control function is operated by
means of the cruise control lever.
The cruise control lever is the uppermost
lever on the left-hand side of the steering
column (
page 22).
Warning!
G
Cruise control is a convenience system de-
signed to assist the driver during vehicle op-
eration. The driver is and must remain at all
times responsible for the vehicle speed and
for safe brake operation.
Only use cruise control if the road, traffic
and weather conditions make it advisable to
travel at a steady speed.
The use of cruise control can be danger-
ous on winding roads or in heavy traffic
because conditions do not allow safe
driving at a steady speed.
The use of cruise control can be danger-
ous on slippery roads. Rapid changes in
tire traction can result in wheel spin and
loss of control.
Deactivate cruise control when driving
in fog.
The “Resume” function should only be oper-
ated if the driver is fully aware of the previ-
ously set speed and wishes to resume this
particular preset speed.
