position
2Current program mode
The current gear range/gear selector lever
position and program mode (
C/S) appear
in the multifunction display.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.
When the gear selector lever is in
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 ofP orN 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 and when
your right 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 parking po-
sition P 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.

Gear ranges
With the gear selector lever in positionD
and driving in the automatic shift
programC orS (
page 176), you can
select a gear range for the automatic
transmission to operate within:
Gear selector lever (page 177):
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+).
Steering wheel gearshift control (CLK 500)
(
page 178):
You can limit the gear range by pressing
the respective downshift button on the
steering wheel gearshift control, and
reverse the gear range limit by pressing
the respective upshift button on the
steering wheel gearshift control.The selected gear range appears in the
multifunction display (
page 171). If you
press on the accelerator when the engine
has reached its rpm limit, the transmission
will upshift beyond any gear range limit
selected.

in mountainous regions
under extreme operating

æ
The transmission operates in

indicated in the multifunction display
(
page 171).
Press program mode selector
switch1 repeatedly until the letter of
the desired program mode appears in

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.
!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.iThe last selected program
mode (CorS) is switched on when the
engine is restarted.

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 175).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.
Canceling gear range limit
Press and hold the gear selector lever
in theD+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 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.
!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.

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.

(Limp-Home Mode)
If vehicle acceleration becomes less re-
sponsive, sluggish, or the transmission no
longer shifts, the transmission is most like-
ly operating in limp-home (emergency op-
eration) mode. In this mode only second
gear and reverse gear can be selected.
Stop the vehicle.
Move gear selector lever toP.
Turn off the engine.
Wait at least ten seconds before
