Braking
New brake p ads
New b rake pads do no t achieve the ir full b raking
effect during the firs t 250 mi (400 km) . They
m ust be "broken in" first .
Wear
Brake pad wear depends largely o n the way the
ve hicl e is driven and on operat ing cond it ions.
This is especi ally true if you are d riving frequently
in the c ity and on c urves or with a sporty driving
style.
Operating noise
Noises may occur when bra king depend ing on the
speed, b raking force and outs ide cond it ions s uch
as temperature and humidity.
Effect of water and road salt
In ce rtain s ituations, for example after driving
through water, in heavy ra in, afte r ove rnight con­
densat ion or after washing your car, the b raking
effect can be red uce d by mo isture or ice on the
b rake rotors and brake pads. The brakes must be
"dried" first with a few careful brake applica­
tions.
At highe r speeds and with t he windshie ld wipers
turned on, the brake pads press against the bra ke
rotors for a short amount of time . This action,
which is not felt by the driver, happens at regular
intervals and ens ures a better reaction time for
the brakes in wet weathe r.
The braking effect can also be reduced if you are
driving on sa lted roads and you do not apply t he
brakes for long periods of time. The layer of salt
on the brake rotors and pads must be worn off
first when the brakes are applied.
Corrosi on
Leaving the vehicle parked for long periods of
time, low mi leage and avo iding heavy brak ing
can contribute to corrosion on the brake rotors
and to d irty brake pads.
If you usually avoid heavy b raking or if there is
corros ion present, occasional heavy braking at
122
high speeds is recommended to clean the brake
rotors and pads¢.&. .
Brake system malfunction
if you not ice that the b rake peda l t ravel has sud­
denly increased, then a br ake circuit in the du al­
c irc uit b rake system may have malfunctioned.
Drive to an authorized A udi dealer or authorized
A udi Se rvice Facility immediate ly to have the
problem corrected. On the way there, drive w ith
reduced speed and keep in m ind t hat you will
need a longer distance to stop and you will need
to press the brake peda l harder .
lo w b rake fluid level
When the brake fluid level is low, malfunctions in
the brake system may occur. The brake fluid level
i s electronically monitored.
Brake booster
The brake boos ter amp lifies the pressure you ap ­
ply to the brake pedal. It only works when the en­
gine is running .
A WARNING
- Only app ly the brakes for the purpose o f
cleaning the brake system when road and
traffic conditions permit. You must not en­
danger other road users. This i ncreases the
r is k of an accident .
-
- Never let the ve hicle roll while the engine is
s topped because this i ncreases the ris k of an
accident .
- New brake pads do no t ach ieve the ir full
braking effect dur ing the first 250 m i
( 4 00 km). They m ust be "b roken in" fi rst.
However, you can compensa te fo r the
slightly reduced brak ing force by pressing
firm ly on the brake pedal. Avo id heavy brak ­
ing during the break-in period.
- Ce rtain weather and operating condi tions
such as d riving through water, dr iv ing in
heavy rain o r driv ing after washi ng your ve­
hicle can impai r the effectiveness of the
brakes. In the winter, ice may build up on
the brake pads, rotors and dr ums. Check

plying the brakes carefully several times
dries the brakes and removes ice bui ld-up.
- The effic iency of the brakes can also be im­
paired by driving for long stretches on roads
covered w ith salt without using the brakes.
You can remove salt deposits from the brake rotors and pads by ca ref ull y applyi ng
the brakes severa l t imes.
- If the front spo iler is damaged or you install
another spoiler, ma ke sure the front w heel
bra kes are vent ilated p roperly. O therwise,
t h e brake syste m could ove rheat, wh ic h re­
duces the ir effec tiveness.
- Failure of a bra ke circuit impai rs b raking
performan ce, which incre ases bra king dis­
tance . Avoid driving the vehicle and have it
towed it to the nearest authorized A udi
dealer or author ized Audi Service Facility .
- If the brake booste r is not working, you wi ll
have to press m uch ha rder on the bra ke
peda l to compensate for the lac k of the
booster.
(D Note
- Never let the brakes "rub" by pressing the
p edal light ly when bra king is not actually
necessa ry. This causes the brakes to over­
heat and increases bra king d istance and
causes wear.
- Befo re driving downh ill a long distance on a
steep h ill, decrease your speed and select a
l ower gear. This makes use of the engine
braking effect and relieves the brakes. If
you need to b rake additionally, brake in in­
te rvals and not cont inuous ly .
(0 Tips
- If the brake booster is not working, you
must p ress the brake pedal with much mor e
fo rc e th an norma l.
-If you re trofit your vehicle wi th a front spoil­
er, whee l covers o r similar items, ma ke sure
t h at t he ai r flow to the front whee ls is not
i nte rru pted. Ot he rw ise the brake sys tem
c a n become too hot.

Indicator lights and messages
• Do not dr iv e vehicle: steering defective
If this indicator light turns on and stays on and
t hi s message appears, the power steering may
have failed.
Stop the vehicle in a safe location as soon as pos­
s ible. Do
not cont inue driving. See an authorized
Audi dealer or authorized A udi Service Fac ility for
ass istance.
,~n Stee ring: System fault You can continue
driving
If the indicator light turns on and the message
appea rs, the steering whee l may be more diffi ­
cul t to move o r more sensitive than us ual. The
steering wheel may also be at an ang le when
driv ing straight.
Drive slowly to an a uth orized Audi dea ler or a u­
t h orized Audi Service Facility to have the mal­
f unct ion corrected.
,Ion Dynamic steering: Initiali zing
If the indicator light is blinking and this message
appea rs, dynam ic steering* is be ing ini tialized.
T he s teer ing whee l will be easy to move a fter
sta rt ing the engine. Re -ini tialization mig ht be
necessary if the steering w heel was moved hard
to the left and right while the ve hicle was not
moving. The d isp lay turns off if the init ialization
was s uccessful.
(D Tips
- If the . or
,Ion indicato r light only stays on
for a short time, you may continue driving.
- The dynamic steering stability systems

A WARNING
Overloading a ve hicl e can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death .
-Carrying more weight than your vehicle was designed to carry will prevent the vehicle
from handling properly and
i ncrease the risk of the loss of
vehicle control.
-The brakes on a vehicle that has been overloaded may not
be able to stop the vehicle
within a safe distance.
- Tires on a vehicle that has
been overloaded can fail sud­
denly, including a blowout and
sudden deflation, causing loss
of control and a crash.
- Always make sure that the to­
tal load being transported -
i ncluding the weight of a trail ­
er hitch and the tongue
weight of a loaded trailer -
does not make the vehicle
heavier than the vehicle's
Gross Vehicle Weight Rating.
Determining correct load
limit
Use the example below to calcu­ late the total weight of the pas -
224
sengers and luggage or other
things that you plan to transport so that you can make sure that
your vehicle will not be overload­
ed.
Steps for Determining Correct Load Limit
1. Locate t he statement "THE
COMBINED WE IGH T OF OCC U­
PANTS AND CARGO SHOULD
NEV ER EXCEED XXX KG OR XXX
LBS"on your vehicle's placard
(tire inflation pressure label)
¢ page 220, fig . 190 .
2. Determine the combined
weight of the driver and pas­
sengers that will be r iding in
your vehicle.
3. Subtract the combined weight
of the driver and passengers
from
"XXX" kilograms or "XXX"
pounds shown on the sticker
¢ page 220, fig. 190.
4. The resu lting fig ure equals the
available amount of cargo and luggage load capacity. For ex ­
ample, if the "XXX" amount
equals 1400 lbs . and there will
be five 150 lbs . passengers in
your vehic le, the amount of
available cargo and luggage load capacity is 650 lbs . .,.
