& WARNING
• USA models: If the BRAKE warning light and the r i,~ warning
light come on together, the rear wheels could lock up first under
hard braking . Rear wheel lock-up can cause loss of vehicle control
and an accident . Have your vehicle repaired immediately by your
authorized Audi dealer or a qualified workshop . Drive slowly and
avoid sudden, hard brake applications.
• Canada models : If the brake warning light (CD) and the ABS
warning light :::; come on together, the rear wheels could lock up
first under hard braking. Rear wheel lock -up can cause loss of
vehicle control and an accident. Have your vehicle repaired imme­ di ately by your authorized Audi dealer or a qualified workshop .
Drive slowly and avoid sudden, hard brake applications.
• If the brake warning/indicator light does not go out after a few
seconds and the parking brake released, or lights up while you are
driving, the fluid level in the brake fluid reservoir is too low. If you
believe that it is safe to do so, proceed immediately at low speed
to the nearest authorized Audi dealer or qualified repair facility
and have the brake system inspected.
• Always keep in m ind that after several brake applications , you
will need greater pressure on the brake pedal to stop your vehicle.
Do not rely on strained brakes to respond with maximum stopping
power in critical situations. You must allow for increased braking
distances. The extra distance used up by fading brakes could lead
to an accident. •

Low brake fluid l evel
Ma lf u nctions can occ ur in the brake system if the brake fluid level is
too low . T he brake flu id level is monitored e lec tron ically .
Brake lining wear statu s
Brake lining wear may be checked by visua l inspection of the condi­
t ion of t he brake pads through the open ings in the whee l. If neces ­
sary, the wheel may be removed fo r thi s inspection~

"Changing a whee l".
& WARNING
• You should p erform braking maneuvers for the purpo se of
cleaning the brake system only if road condit ions permit. Other
road u sers must not be put at risk - you may cau se an accident!
• Befo re descending a steep grade, reduce speed and sh ift t rans ­
mission into a lower gear or lower driving range. Do not ride the
brakes or hold the pedal down too long or too often. Th is could
cause the brake s to get hot and diminish braking efficiency.
• Do not "ride the b rakes " by resting your foot on the pedal when
you do not intend to brake. Thi s may cau se the brakes to overheat ,
premature wear and increased stopping distance.
• Under certain climatic and operating condition s such as
passing through water, driving 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 test. Brake s will dry and ice coating s
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 also affect brak ing efficiency. Clean
off accumulated salt co ating from brake disc s and pads with a few
careful brake applications.
• If you damage the front spoiler , or if you in stall a different
spoiler , be sure the air flow to the front brakes is not obst ructed.
Otherwi se the brake system could overheat reducing the effective­
ness of the entire brake system .
& WARNING (c on tinued )
• Failure of one brake circuit will impair the braking capability
resulting in an increa sed stopping di stance. Avoid driving the
vehicle and have it towed to the nearest Audi dealer or qualified
workshop. •
Brake booster
The brake booster adds extra brakin g po wer.
Th e bra ke booster wor ks with vacuu m pressure which is created on ly
when the eng ine is running ~& .
& WARNING
• Never let the vehicle roll to a stop with the engine shut off.
• If the brake booster is not working , for e xample when towing
y our vehicle , or be cause the brake booster has somehow been
damaged , the brake pedal must be pressed considerably harder to
make up for the lack of boo ster assistance. •
Functioning of Anti-Lock Brake System
(ABS)
AB S prevents the wh eels from locking up under braking .
The ABS co ntrib utes effe ctive ly to ve hicl e con tro l s in ce i t preven ts t he
wheels from
locking when the brakes are applied . This means that the
vehicle remains steerable and is less likely to s kid.
With ABS you do not need to pump the brake. Just hold the brake
pedal down.
However, do not expect t he A BS to sho rten b raking di stan ce u nder all
circumstances. W hen driving on grave l or on newly fa llen snow on top
of icy s urfaces, braking distance may be even longer, therefore, under .,_
