204 Controls in detailAutomatic transmissionRocking the vehicle
Rocking the vehicle by shifting betweenD
andR can help free a vehicle stuck in mud
or snow. The engine control system of this
vehicle electronically limits shifting
betweenD andR to very low speeds
(i.e. approx. 2 mph). To shift betweenD
andR, move the gear selector lever past
the resistance point up or down.
Hill start assist system
On uphill grades, the hill start assist
system maintains the pressure in the
brake system for approximately 1 second
after you have released the brake pedal.
Therefore, you can start off smoothly with-
out the vehicle moving immediately after
releasing the brake pedal.
The hill start assist system is inactive

Automatic transmission
The current gear range/transmission
position (
page 199) and the selected
program mode (
C/S) are indicated in the
multifunction display.
1Current program mode
Press program mode selector switch
repeatedly until the letter of the de-
sired program mode appears in the
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.
Steering wheel gearshift control
With drive positionD selected, you can use
the steering wheel gearshift control but-
tons to manually shift the gears. When
doing so, you are also limiting or extending
the gear range.
!Never change the program mode when
the automatic transmission is out of
park 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.
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.
