Hill descent control
The hill descent control is switched on in off-
road mode. When slowly descending steep
gradients on loose ground or when the axles
are articulated, hill descent control provides
assistance by automatically applying the
brakes to keep vehicle speed constant. The ve-
hicle is also rendered easier to steer by selec-
tive distribution of braking force . Hill descent
control intervenes when:
- the accelerator pedal is not pressed,
- the vehicle is trave lli ng less than 12 mph
(20 km/h),
- a steep gradient is detected,
- wheel behavio r indicates loose ground or
conditions with poor adhesion (e.g. also axle
articulation) .
Hill descent control operates both dr iving f or-
ward and in reverse. Active hill descent con-
trol is deactivated by pressing the accelerator
pedal until the conditions for activation al-
ready listed are met again.
A WARNING
You should only switch offroad mode on if
your dr iving abilities and road cond itions
permit.
- The stabilization function is limited
when offroad mode is switched on. The
dr iving wheels could spin and the vehicle
could swerve, especially on slick or slip-
pery road surfaces.
- You should only switch offroad mode on
when driving offroad.

Brake system
Operating conditions and driving habits
The brakes on today's automobiles are still
subject to wear, depending largely on operat-
ing conditions and driving habits
c> Li::,.. On
vehicles that are either driven most ly in stop-
and-go city traffic or are dr iven hard, the
brake pads should be checked by your author-
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 continuously. Pump the brakes at inter-
vals.
Noises may occur when braking depending on
the speed, braking force and outs ide cond i-
tions such as temperature and humidity.
Moisture or road salt
Under certa in 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
freezing cond iti ons ice) on the brake pads. A
f ew careful brake applications should dry off
the brake pads or remove any ice coatings.
