Driving
fully interrupted even when the engine is
idling.
- The accelerator pedal must on no account
be pressed inadvertently when the vehicle is
stationary. The vehicle could otherwise start
moving immediately (in some cases even if
the parking brake is engaged) and possibly
cause an accident.
- Do not press the accelerator while selecting
a gear with the vehicle stationary and the
engine running, as this could cause an acci
dent.
- Never move the selector lever to R or P
when driving at normal speeds, as this could
cause an accident.
- Before you drive down a steep gradient, re
duce the speed and use "tiptronic" to select
a low gear.
- Never allow the brake to drag when driving
downhill and do not use the brake pedal too
often or for long periods. Constant braking
will cause the brakes to overheat and will
considerably reduce the effectiveness of the
brakes. It will increase the braking distance
and could cause the brake system to fail.
- To avoid rolling back on gradients always
hold the vehicle with the footbrake or park
ing brake if you have to stop.
- Never attempt to hold the vehicle with the
clutch when stopping on a gradient. The
clutch is disengaged automatically if it is
overloaded and becomes too hot - accident
risk! If the clutch is overloaded, the indica
tor lamp
51
will light up and a message will
appear

CAUTION
- When you have stopped on a gradient, do
not try to stop the vehicle rolling back by ac
celerating when a gear is engaged. This
could cause the automatic gearbox to over
heat and become damaged. Apply the park
ing brake or press the brake pedal in order
to prevent the vehicle from rolling back.
- If you allow the car to roll with the selector
lever in position N with the engine switched
off, the automatic gearbox will be damaged
as it will not be lubricated.

- In certain driving and traffic conditions, for
instance in stop-and-go traffic, if you have
to pull away frequently or if the vehicle
creeps forwards over a long distance, the
gearbox can overheat and become dam
aged. If the indicator lamp
51
or the warn
ing lamp
.
lights up, stop the vehicle at
the first opportunity and let the gearbox
cool down
¢page 83.
- If you allow the car to roll with the engine
switched off, the S tronic gearbox will be
damaged as it will not be lubricated

Note
For safety reasons the parking brake will only
release automatically if the driver's seat belt
is engaged in its buckle.
Downhill speed control
Applies to: vehicles with automatic gearbox
The downhill speed control function helps the
driver when driving down steep gradients.
Downhill speed control is activated on a downhill
gradient when the selector lever is in D/S and the
driver presses the brake pedal. The gearbox auto
matically selects a suitable gear for the gradient.
The downhill speed control function attempts to
maintain the speed at which the vehicle was trav
elling when the foot brake was applied (subject
to the laws of physics and technical limitations of
the power train). It may be necessary to adjust
the speed again using the foot brake. The down
hill speed control can change down to 3rd gear
but no further, so it may be necessary to change
to tiptronic mode on very steep gradients. In this
case, change down manually to 2nd or 1st gear in
tiptronic mode to use the engine braking effect
and reduce the load on the brakes.
Downhill speed control is deactivated as soon as
the road levels out again or you press the acceler
ator pedal.
On vehicles with cruise control system*

page 86,
downhill speed control is activated
when you set a cruising speed.
