Press program mode selector
switch1 repeatedly until the letter of
the desired program mode appears in
the right multifunction display.
SelectCfor comfort 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.Gear selector lever one-touch
gearshifting
Even with an automatic transmission, you
can change the gears manually and limit or
extend the gear range for automatic
shifting with the gear selector lever in
positionD and driving in the automatic
program modeC orS.Downshifting

Briefly press the gear selector lever to
the left in theD-direction.
The transmission will shift from the current
gear to the next lower gear as permitted by
the shift program. This action simulta-
neously limits the gear range of the
transmission (
page 172).
!
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.
i
The last selected program mode (CorS) is
switched on when the engine is restarted.
!
Allow engine to warm up under low load use.
Do not place full load on the engine until the op-
erating 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.
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.i
To 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.

Upshifting
Briefly press the gear selector lever to
the right in theD+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.

in theD+direction until
D reappears in
the right 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 theD-direction.
The transmission will automatically select
the gear range suited for optimal
acceleration and deceleration. This may
involve shifting down one or more gears.Steering wheel gearshift control

Manual shift program (SL 55 AMG and SL 65 AMG only)
In addition to the automatic shift
programC orS, your vehicle is equipped
with the manual shift program MANUAL.
In the MANUAL program mode,
system-controlled automatic gearshifting
is switched off and you need to change the
gears by manually upshifting or downshift-
ing using the steering wheel gearshift pad-
dles (
page 175) or the gear selector
lever.The program mode selector switch is
located on the lower part of the center
console.

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


Distance warning function* (only avail-
able with Distronic*), which warns of
stationary objects or slower moving ve-
hicles that you are closing in on too
quickly


ABC with vehicle level control systems,
with which you can change vehicle sus-
pension characteristics


Parktronic*, which assists the driver
during parking maneuvers
For information on the BAS, ABS, ESP
®,
and the electro-hydraulic brake system,
see “Driving safety systems” (
page 87).
Cruise control
The cruise control automatically maintains
the speed you set for your vehicle.
The use of the cruise control is recom-
mended for driving at a constant speed for
extended periods of time.
You can set or resume the cruise control at
any speed above 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 24).
Warning!
G
The cruise control is a convenience system
designed to assist the driver during vehicle
operation. The driver is and must always
remain responsible for the vehicle’s speed
and for safe brake operation.
Only use the cruise control if the road,
traffic, and weather conditions make it ad-
visable to travel at a constant speed.

The use of the cruise control can be dan-
gerous on winding roads or in heavy traf-
fic because conditions do not allow safe
driving at a constant speed.


The use of the cruise control can be dan-
gerous on slippery roads. Rapid changes
in tire traction can result in wheel spin
and loss of control.


Deactivate the cruise control when driv-
ing 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.
