& WA RNING (conti nu ed )
• Do not "ride the brakes " by re sting your foot on the pedal when
you do not intend to brake . Thi s may cause the brakes to overheat,
premature wear and increased stopping distance.
• Under certain climatic and operating condition s such as
pa ssing through water, dr iving in heavy rain or after washing the
vehicle, the effectiveness of the brake s can be reduced . In winter ,
ice can accumulate on the brake pads , linings , discs and drums .
Carefully apply brakes for a te st. Brakes will dry and ice coatings
will be cleaned off after a few careful brake applications.
• Driving for an extended period of time on salt-covered roads
without using your brakes can al so affect br aking efficiency. Clean
off accumulated salt coating from brake disc s and pads with a few
careful brake applic ations.
• If you damage the front spoiler , or if you in stall a different
spoile r, be sure the air flow to the front brakes is not obstructed.
Otherwi se th e brake system could overheat reducing the effective­
ness of the entire brake system.
• Failure of one brake circuit will impair the braking capability
resulting in an inc reased stopping distance. Avoid driving the
vehicle and have it towed to the nearest authorized Audi dealer or
qualified wo rkshop .

Brake booster
T h e brake booste r adds ext ra braking p ower.
The brake booster works with vacuum pressure which is created on ly
w hen the eng ine is ru nnin g=>&.
& WARNING
• Never let the vehicle roll to a stop with the engine shut off.
• If the brake boo ster i s not working , for example when towing
your veh icle , or because the brake booster has somehow been
& W ARNING (continued )
damaged , the brake pedal must be p ressed considerably harder to
make up for the la ck of booster assi stan ce. •
Functioning of Anti-Lock Brake System
{ABS)
ABS prevents the wheels from l ockin g up under br aking.
Th e ABS contr ibutes effectively to vehicle co ntrol s ince it prevents t he
w heels from
locking when the brakes are applied . This means that the
veh icle rema ins steerable and is less likely to skid .
With ABS you do not need to pump the brake. Just hold the brake
pedal down .
However, do no t expect that the ABS shortens bra king d istance under
all circumstances . When dr iv ing on grave l or on newly falle n snow on
top of icy s urfaces, braking d istance may be even longer, therefo re,
under these circumstances, it is especially important that yo u drive
slowly and with g re at c are.
How the ABS system works
An au tomatic c hec k is made when a speed of about 4 mp h (6 km/ h) is
reached. When t his happens, a pump ing noise can be heard.
If an ind ivi dual wheel begi ns to rot ate too s low ly in relat ion to ve hicle
speed and tends to loc k, t he ABS automatically reduces brake pres­
s ur e to p revent t hat wheel from lo cking.
T hi s au tomatic adjustment p rocess w ill cause a
s light vibration of
the bra ke pedal and some noises to a lert you that vehicle speed must
be adapted to ex isting road and traffic co nditions .
& WARNING
Although the ABS is very effective, always remember that braking
capability is limited by tire traction. Always adjust your driving ...
