Driving
Under certain circumstances, (such as driving in
the mountains or towing a trailer), it may be use-
ful to switch temporarily to the manual shift pro-
gram in order to manually adapt the gear to the
driving conditions
c::> page 71.
On inclines, activate the parking brake first and
then move the selector lever to the P position
c::> page 65. This prevents the locking mechanism
from being loaded too heavily and will make it
easier to move the selector lever out of the P po-
sition .
_& WARNING
- The vehicle can also roll when the engine is
stopped.
- Unintended vehicle movement can cause se-
rious injury.
- 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/
Sor 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
"tiptron ic".
- 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 . illuminates
and a driver message appears
c::> page 72
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 159. 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-
lected. This can cause the automatic trans-
mission to overheat and can damage it. Set
the parking brake or press the brake pedal
to prevent the vehicle from rolling.
- Allowing the vehicle to roll when th@ engine
is stopped while the selector lever is in the
N position will damage the automatic trans -
mission, because it is not lubricated under
those circumstances
c::> page 211, Towing
with a tow truck.
- The transmission can overheat and be dam-
aged under certain driving and traffic condi-
tions such as frequent starts, creeping for a
long time, or stop-and-go traffic. If the .
indicator light turns on, stop the vehicle at
the next opportunity and let the transmis-
sion cool down

Hill descent control
The hill descent control system assists the driver
when driving down hills.
Hill descent control is activated when the selec-
tor lever is in the D or S position and you press
the brake pedal. The transmission automatically
selects a gear that is suitable for the hill. Hill de-
scent control tries to maintain the speed ach-
ieved at the time of braking, within physical and ..,.
