If the engine must run while you are work-
ing in the engine compartment with the
hood open, make sure a gear is not engag-
ed. The selector lever must be firmly in the
P position and locked in place and the park-
ing brake must be set¢ page 236. Other-
wise, the vehicle could begin moving when
the engine speed is high, even with
t
he
par king brake set.

Note
-
When stopping on
an
incline, do not t ry to
hold the vehicle in place by press ing the ac-
celerat or
pedal wh ile
a
driving gear is se-
lected. This can cause the
aut
oma
t ic
trans-
mission to overheat and can damage it. Set
the pa rking brake or press the brake pedal
to prevent the vehicle from
rolling.
- Allowing the vehicle
t
o
roll
when the eng ine
is stopped and the se lector lever is in the N
pos ition will damage the automatic trans-
mission because it is not lubricated under
those circumstances.
- The transmiss ion 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. When t he
mJ
or
.
ind icator light tu rns on,
st
op the
vehicle at the next oppo rt unity and let the
transm
ission cool

Hill descent control
Applies to vehicles: with S
tro
nic
transmission
The hill descent control system assists the driver
when driving down hills.
Hill descent control is act ivated when the se lec-
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
incline. Hill
descent
cont
rol tr ies to maintain
t
he speed ach-
ieved
at
the
t
ime of braking, wit hin physical and
technical limitations
.
If may
st
ill be necessary to
adjus
t
the speed with the bra kes
.
Because
hill de-
scent control cannot shift down farthe
r
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 decline
levels out or you press the accelerator pedal.
On vehicles with a cru ise

rol system*

hill
descent control is also activated
when the speed is set.
A
WARNING
-
Hill descent control cannot overcome physical
limitat ions, so it may not be able to ma intain
a constant speed under all conditions. Always
be ready to app ly
t
he brakes.
