- Never leave your vehicle with the engine
running while in gear. If you must leave
your vehicle when the engine is running, ac-
tivate the parking brake and move the selec-
tor lever to P.
- Power is still transmitted
to the wheels
when the engine is running at idle. To pre -
vent the vehicle from "creeping", you must
keep your foot on the brake when the en-
gine is running and the selector lever is in D/
5 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, reduce
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 brak-
ing distance or causes complete failure 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 automati-
cally when it becomes too hot from the
overload . An indicator lamp
[ijJ
illuminates
and a driver message appears c> page 126
when the clutch is overloaded .
- If the engine must remain running, never
have any driving position engaged when
checking under the hood.
Make
sure these-
lector lever has securely engaged and is
locked in P with the parking brake set
c> page 220. Otherwise, any increase in en-
gine speed may set the vehicle in motion,
even with the parking brake applied.
(D
Note
- When stopping on an incline, do not try to
hold the vehicle in place by pressing the ac-
celerator pedal while a driving gear is se-
Automatic
transmission
lected. This can cause the transmission to
overheat and can damage it. Activate the
parking brake or press the brake pedal to
prevent the vehicle from rolling.
- Allowing the vehicle to roll when the engine
is stopped and the selector lever is in N will
damage the transmission because it is not
lubricated under those circumstances.

Tips
For safety reasons, the parking brake is re-
leased automatically only when the driver's
safety belt is engaged in the buckle.
Hill descent control
The hill descent control system assists the driver
when driving down decline s.
Hill descent control is act ivated when the selec-
to r lever is in D/S and you press the brake pedal.
The transmission automatically selects a gear
tha t is suitable for t he incline. Hill descent con-
trol tries to maintain the speed achieved at the
time of braking, within physical and technical
limitations. It may still be necessary to adjust the
speed with the brakes .
Hill descent control switches off once the decline
levels out or you press the accelerator pedal.
When the speed is set in the cruise control sys-
tem
c>
page 95 , hill descen t control is also act i-
vated .
A
WARNING
Hill descent control cannot overcome physical
limitations, so it may not be able to maintain
a constant speed under all conditions . Always
be ready to apply the brakes.
