As soon as the test is comp leted, the system
is in normal operating mode.
Switching off
ESP should normally be activated at all times
because this ensures optimum vehicle stabil i-
ty. In certa in situations, it might make sense
to allow some slip. For example:
- Rocking the vehicle to free it when it is stuck
- Driving in deep snow or on loose ground
- Driving with snow chains
Press the
[!I button . The ESP indicator light I)
turns on and Stabilisation program off ap-
pears in the display. ASR deact ivates com-
pletely and the stab ilizat ion effects from the
ESP system are lim ited.
Switching on
Press the [!I button again. The message Stabi·
lisation program on
appears briefly in the dis-
play.
A WARNING
You should only switch the ESP off if your
driving ability and the traffic situation per-
mit. Please note that when ESP/ASR is de-
activated, the drive wheels can spin on icy
and slippe ry roads and the vehicle can
break away - danger of skidding!
(j) Tips
If Audi magnetic ride* is malfunctioning,
the ESP may not switch off or it may
switch off automatically.
Braking
General information
What affects braking efficiency?
Operating condit ions and driving habit s
The brakes on today's automobi les are still
subject to wear, depending largely on operat-
ing conditions and driving habits q .&.. On ve-
hicles that are either driven mostly in stop-
and-go city traffic or are driven hard, the
brake pads should be checked by your author-
Int e llig e nt technolog y 163
ized Audi dealer more often than specified in
the Warranty & Maintenance booklet. Failure
to have your brake pads inspected can result
in reduced brake performance.
On steep slopes, you should use the braking
effect of the engine. This way, you prevent un-
necessary wear on the brake system. If you
must use your brakes, do not hold the brakes
down cont inuously. Pump the brakes at inter-
vals.
Noises may occur when braking depending on
speed, braking force and outs ide condit ions
such as temperature and humidity.
Moisture or road salt
If you are driving faster than SO mph (80 km/
h) and the windshield wipers are on, the brake
pads will briefly touch the brake discs in regu-
lar intervals so as to improve reaction time
when braking on wet surfaces. You, the driver,
will not not ice anything.
Under certain conditions, for example, when
driv ing through water or very heavy rain, or
even after washing your vehicle, the braking
effect can be reduced due to moisture (or in
freez ing conditions ice) on the brake pads. A
few cautious brake applications should dry off
the brake pads or remove any ice coatings.
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered
road and the brakes are not used. l ikewise,
you clean off accumulated salt coating from
brake discs and pads with a few cautio us ap-
plications of the brake
¢ .&,.
Corrosion
There may be a tendency for dirt to build up
on the brake pads and corrosion to fo rm on
the discs if the car is not driven regularly or
only for short tr ips with litt le use of the
brakes.
If the brakes are not used frequently, or if cor-
rosion has formed on the discs, it is advisable
to clean off t he pads and discs by braking
firmly a few times from a moderately high
speed ~ .&.. .,.
