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+).

could result in a change of driving characteristics
for which you may not be prepared.

Press program mode selector switch
repeatedly until the letter of the
desired program mode appears in the
multifunction display.
SelectCfor comfort driving
(CLS 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
(CLS 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 176).
i
For information on using the gear selector
lever in program modeM, see “Manual shift pro-
gram CLS 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 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 down-
shifting, the transmission will not shift to a lower
gear if the engine’s max. speed would be
exceeded.

Extending gear range
Briefly press the gear selector lever to
the right in theD+direction.
The transmission will shift to the next
higher gear as permitted by the shift
program. This action simultaneously
extends the gear range of the transmis-
sion.
Canceling gear range limit

the multifunction display (page 173).
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 will
involve shifting down one or more
gears.Steering wheel gearshift control

Steering wheel gearshift control is avail-
able on vehicles with AMG-Sport Package*
and CLS 63 AMG only.
With the gear selector lever in drive
positionD and driving in program modeC

If you press on the accelerator when the en-
gine has reached its rpm limit, the transmission
will upshift beyond any gear range limit selected.

In the manual program modeM, the trans-
mission will not upshift, even if the engine has
reached its overrevving range. Shift up to the
next gear before the engine has reached its over-
revving range. Make absolutely certain that the
engine speed does not reach the red marking on
the tachometer (
page 26). Otherwise the
engine could be damaged which is not covered
by the Mercedes-Benz Limited Warranty.
