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 automatic
transmission to overheat and can dam-
age it. Set 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 th@ selector lever is
in the N position will damage the auto-
matic transmission because it is not lu-
bricated under those circumstances .
- The transmission can overheat and be
damaged under certain driving and traf-
fic conditions such as frequent starts,
creeping for a long time , or stop-and-go
traffic. When the
ml
or .
indicator
light turns on, stop the vehicle at the

sion cool

Hill descent control
Appli es to vehicles : wi th S tr onic tra nsmi ssion
Hill descent control assists the driver when
driving down inclines.
Hill descent control is activated when these-
lector lever is in the D or S position and you
press the brake pedal. The transmission auto -
matically selects a gear that is suitable for the
incline. Hill descent control tries to maintain
the speed achieved at the time of braking,
within physical and technical limitations. If
may still be necessary to adjust the speed
with the brakes. Because hill descent control
cannot shift down farther than 3rd gear, it
may be necessary to shift into tiptronic mode
in very steep areas. In this case, shift into 1st
or 2nd gear in tiptronic mode to use the en-
gine's braking force to relieve the brakes.
Hill descent control switches off once the in-
cline levels out or you press the accelerator
pedal.
On vehicles with a cruise control system*
Q
page
79, hill descent control is also activat-
ed when the speed is set.
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.
