Transmission
- Unintended vehicle movement can cause
serious injury .
- Never leave your vehicle with the engine
running while in gear. If you must leave
your vehicle when the engine is running,
activate the parking brake and move the
selector lever to P.
- Power is still transmitted to the wheels
when the engine is running at idle . To
prevent the vehicle from "creeping", you
must keep your foot on the brake when
the engine is running and the selector
lever is in D/S or R or "tiptronic" mode is
selected.
- Do not press the accelerator pedal when
changing the selector lever position
while the vehicle is stationary and the
engine is running.
- Never shift into R or P while driving.
- Before driving down a steep slope, re-
duce your speed and shift into a lower
gear with "tiptronic".
- Do not ride the brakes or press the brake
pedal too often or too long when driving
down a hill. Constant braking causes the
brakes to overheat and substantially re-
duces braking performance, increases
braking distance or causes complete fail-
ure of the brake system.
- To prevent the vehicle from rolling back
when stopping on inclines, always hold it
in place with the brake pedal or parking
brake.
- Never hold the vehicle on an incline with
a slipping clutch . The clutch opens auto-
matically when it becomes too hot from
the overload . An indicator lamp

minates and a driver message appears

when the clutch is overload-
ed.
- If the engine must remain running, never
have any driving position engaged when
checking under the hood. Make sure the
selector lever has securely engaged and
is locked in P with the parking brake set

Oth-
erwise, any increase in engine speed may
set the vehicle in motion, even with the
parking brake applied.

Note
- When stopping on an incline, do not try
to hold the vehicle in place by pressing
the accelerator pedal while a driving gear
is selected. This can cause the transmis-
sion to overheat and can damage it. Acti-
vate the parking brake or press the brake
pedal to prevent the vehicle from rolling .
- Allowing the vehicle to roll when the en-
gine is stopped and the selector lever is
in N will damage the transmission be-
cause it is not lubricated under those cir-
cumstances.

Tips
For safety reasons, the parking brake is re-
leased automatically only when the driv-
er's safety belt is engaged in the buckle.
Hill descent control
The hill descent control system assists the
driver when driving down declines.
Hill descent control is activated when these -
lector lever is in D/S and you press the brake
pedal. The transmission automatically selects
a gear that is suitable for the incline. Hill de-
scent control tries to maintain the speed ach-
ieved at the time of braking, within physical
and technical limitations. It may st ill be nec-
essary to adjust the speed with the brakes.
Hill descent control switches off once the de-
cline levels out or you press the accelerator
pedal.
On vehicles with the cruise control system*
Q
page 82 ,
hill descent control is also activat-
ed when the speed is set.

WARNING
-
Hill descent control cannot overcome
physical limitations, so it may not be able
to maintain a constant speed under all
