- There is no vehicle stabilization when ESC/
ASR are switched off.
(D Tips
- Malfunctions in the rear spoiler, in the Audi
magnetic ride or in the all wheel drive sys-
tem may make it impossible to switch the
ESC/ASR off or to switch sport mode on.
- Some driving tracks (such as ones with
steep curves) can influence the ESC per-
formance.
Brakes
New brake pads
New brake pads do not achieve their full braking
effect during the first 2SO miles (400 km) . They
must be "broken in" f irst. The break-in period can
be considerably longer for vehicles with ceramic
brake rotors* . However, you can compensate for
the slightly reduced brak ing fo rce by pressing
f irm ly on the brake pedal. Avoid heavy braking
during the break-in period.
W ear
Brake pad wear depends largely on the way the
vehicle is driven and on operat ing conditions .
This is especially true if you are driving frequently
in the city and on curves or with a sporty driving
style.
Operat ing noise
Noises may occur when braking depend ing on the
speed, braking force and outs ide conditions such
as temperature and humidity .
Noises may become more apparent at lower
speeds due to the nature of the mater ials in the
ceramic brake rotors*.
Effect f rom water and road salt
In certain situations, for example after driving
through water, in heavy rain, after overnight con-
densat ion or after washing your car, the braking
effect can be reduced by moisture or ice on the
brake rotors and brake pads. The brakes must be
"dr ied" first w ith a few careful brake applica-
tions .
Intellig e nt Technology
At higher speeds and with the windshield wipers
turned on, the brake pads press against the brake
rotors for a short amount of time. This action
which is not felt by the dr iver happens at regu lar
interva ls and facilitates a better reaction t ime for
the brakes in wet weather .
The braking effect can also be reduced if you are
driv ing on salted roads and you do not apply the
brakes for long periods of time. The layer of salt
on the brake rotors and pads must be worn off
first whe n the brakes are applied .
Due to its surface, a ceramic brake rotor* absorbs
moisture in certain situat ions. Therefore, there
will temporarily be less braking force than when
the brakes are dry. You can compensate for th is
by pressing the brake pedal harder .
Corrosion
Leaving the vehicle parked for long periods of
t ime, low mileage and avoiding heavy braking
can contribute to corros ion on the brake rotors
and dirty brake pads.
If you usually avoid heavy brak ing or if there is
corrosion present, occasional heavy brak ing at
high speeds is recommended to clean the brake
rotors and pads
Q ,&..
Brake system malfunction
if you notice that the brake pedal travel has sud-
denly
gotten larger, then a brake circuit may have
failed . Drive to an author ized Audi dealer or au-
thorized Audi Service Facility immediately to have
the problem corrected . On the way there, drive
with reduced speed and keep in mind that a long
braking distance and increased pressure on the
brake pedal w ill be necessary.
Low brake fluid level
When the brake fluid level is low, malfunctions in
the brake system may occur. The brake fluid level
is electronically monitored.
Brake booster
The brake booster amp lifies the pressure you ap-
ply to the brake pedal. ..,.
