_& WARNING
-Always observe the w arnings in
¢ page 155, Working in the engine com ­
partment, before opening the engine hood
and checking the b rake fluid .
- Driving with low brake fluid is a safety haz­
ard! Stop the car and get professional assis­
tance.
- USA models: If both, the~ warning
light and the
II warning light come on at
the same time, the rear whee ls cou ld lock
up first under hard braking. lock-up of the
rear wheel brakes can cause loss of veh icle
control and an accident. Have your vehicle
repai red immediately by your author ized
Audi dealer or a qualified wo rkshop. Dr ive
slowly and avoid sudden, ha rd b rake appli­
cat ion .
- Canada models: If both, the brake warning
ligh t. and the ABS warning light
ii] come
on at the same time, the rear whee ls co uld
lock up first under har d braking. lock -up of the rear wheel brakes can cause
loss of vehi­
cle control and an accident. Have your veh i­
cle repaired immed iately by your authorized
Aud i deale r or a qua lified workshop. Drive
slowly and avo id sudden, hard brake appli­
cation.
- If the brake warning/ind icator light does
not go out after a few seconds and the pa rk­
ing brake is released, or lights up wh ile you
are driving, the fl uid level in the brake flu id
reservoir is too low.
If you believe that it is
safe to do so, proceed immedia tely at low
speed to the nearest authorized A udi dealer
or qualified workshop and have the brake
system inspected.
- Always keep in mind that after severa l brake
applications, you will need greater press ure
on the brake pedal to stop your vehicle. Do not rely on strained brakes to respond with
maximum stopp ing power in cr itical s itua­
tions . You must allow for increased braking
distances. The ext ra d istance used up by
fading brakes could lead to an accident.
tli1 !'! r Safety systems
T he . (USA models), . (Canada mode ls) indi­
cator lig ht monitors the safety sys tems e.g. air­
bags, pretensioners and ill uminates for a few
seconds each time you switc h the ignition on .
If the . (USA models)/ . (Canada models) in­
dicator light does not go ou t, o r if i t illumin ates
whi le you a re d riving, or if it starts to blink, then
t h ere is a ma lfunction somewhere in the system .
If the light does not illum inate when yo u switch
on the ignition, this also means there is a ma l­
funct ion.
_& WARNING
-If you have a ma lfunction in the safety sys-
tems, contact you r authorized Audi dea le r i m­
mediately. Otherwise the safety systems may
not wor k properly in an accident.

This can cause a temporary reduction in braking
force compared to dry brakes. You can compen­
sate for this by pressing the brake pedal harder.
Cor ro sion
There may be a tendency for dirt to bui ld up on
the brake pads and corrosion to fo rm on the discs
if the car is not driven regularly or only for short
trips with little use of the brakes.
If the b rakes are not used frequently, or if corro­
sion has formed on the discs, it is advisab le to
clean off the pads and discs by braking firmly a
few times from a moderately high speed

Faults in the brake sy stem
If you should notice a sudden increase in brake
pedal travel, then one of the two brake circuits
may have fai led

Low brak e flu id le vel
Malfunct ions can occur in the brake system if the
brake fluid level is too low. The brake flu id leve l is
monitored e lectronically.
Br ake power assis t un it
T he brake power assist unit increases the pres­
sure that you generate with the brake pedal.
It
works only when the eng ine is running .
Brak e lining wear sta tu s
Brake lining wear may be checked by visual in­
spection of the condition of the brake pads
through the openings in the wheel. If necessary,
the wheel may be removed for this inspection
c:> page 203 .
.8, WARNING
-New brake pads don't have the best stop­
ping power and must be "broken-in" during
the init ial 250 mi les ( 400 km) of normal city
driving. The break -in period can be consider­
ably longer for vehicles with ceramic brake
rotors *. You can compensate for this by
pressing the brake pedal more firmly. This
also applies later when new pads are instal­
led .
- You should perform brak ing maneuvers for
the purpose of clean ing the brake system
Int elli ge nt te chn olo gy
only if road conditions permit. Other road
users must not be put at r isk -you may
cause an accident!
- Before descending a steep grade, reduce
speed and sh ift transmission into a lower
gear or lower dr iving range. Do not ride the
brakes or hold the pedal down too long or
too often. This could cause the bra kes to get
hot and dimin ish braking effic iency .
- Do not "ride the brakes" by rest ing your foot
on the pedal when you do not intend to
brake. This may cause the brakes to over­
heat, premat ure wear and increased stop­
ping distance.
- Under certain cl imatic and operat ing condi ­
tions such as passing thro ugh water, dr iv ing
in heavy rain or after washing the vehicle,
the effectiveness of the brakes can be re­
duced . In winter, ice can accumulate on the
brake pads, lin ings, discs and drums. Care­
fully apply brakes for a test. Brakes will dry and ice coatings will be cleaned off after a
few careful brake applications.
- Driving for an extended period of t ime on
salt-covered roads without using your brakes can also affect braking efficiency .
Clean off accum ulated salt coating from
b rake discs and pads with a few cautious
brake applications.
- If you damage the front spoiler, or if you in­
stall a different spoiler, be su re the air flow
to the front brakes is not obstructed . O ther­
wise the brake system could overheat reduc­
ing the effectiveness of the entire brake sys­
tem .
- Fai lure of one brake circuit will impai r the
braking capability resu lting in an increased
stopping distance . Avoid driving the vehicle
and have it towed to the nearest Aud i dea ler
or qualif ied workshop.
- Never let the vehicle roll to a stop with the
engine shut off.
- If the brake booster is not working, for ex­
ample when towing your veh icle, or because
the brake booster has somehow been dam­
aged, the brake pedal must be pressed con ­
siderably harder to make up for the lack of booster assistance.

Checking and filling
-Move selector lever of S tronic to "N" (Neu­
tral); put manual transmission in Neutral.
- Always let the engine cool down. Hot com­
ponents will burn skin on contact .
- To reduce the risk of being burned, never
open the engine compartment lid if you see
or hear steam or coolant escaping from the
engine compartment. Wait until no steam
or coolant can be seen or heard before care­
fully opening the engine compartment lid.
- Keep children away from the engine com­
partment .
- Never spill fluids on hot engine compo­
nents. They can cause a fire.
- Never open the coolant reservoir cap when
the engine is still warm . The coolant system
is pressurized and hot coolant could spray
out .
- Protect your face, hands and arm from
steam or hot engine coolant by placing a
thick rag over the cap when you open the coolant reservoir .
- Do not remove the engine cover under any
circumstances . This increases the risk of
burns.
- If work on the fuel system or the electrical
system is necessary :
- Always disconnect the battery.
- Never smoke or work near heaters or open
flames. Fluids in the engine compartment
could start a fire.
- Keep an approved fire extinguisher imme­
diately available .
- To avoid electrical shock and personal injury
while the engine is running or being started,
never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repair with
the engine running:
- First, fully apply the parking brake, move
selector lever of S tronic to
"N" (Neutral);
put manual transmission in Neutral.
- Always use extreme caution to prevent
clothing, jewelry, or long hair from getting
caught in the radiator fan, V-belts or other

A WARNING
California Proposition 65 Warning:
- Engine exhaust, some of its constituents,
and certain vehicle components contain or
emit chemicals known to the State of Cali­
fornia to cause cancer and birth defects and reproductive harm. In addition, certain flu­
ids contained in vehicles and certain prod­
ucts of component wear contain or emit
chemicals known to the State of California
to cause cancer and birth defects or other
reproductive harm.
- Battery posts, terminals and related acces­
sories contain lead and lead compounds,
chemicals known to the State of California
to cause cancer and reproductive harms.
Wash hands after handling.
@ Note
When adding fluids, always make sure that
they are poured into the proper container or
filler opening, otherwise serious damage to
vehicle systems will occur.
@ For the sake of the environment
To detect leaks in time , inspect the vehicle
floor pan from underneath regularly. If you
see spots from oil or other vehicle fluids, have
your vehicle inspected by an authorized Audi
dealer .
· Closing the engine compartment lid
.. Make sure that the rear spoiler is retracted
¢page 138 .
.. Pull the engine compartment lid down until the
pressure from the struts is reduced.
.. Press the engine compartment lid closed
¢ _A . ..,

Checking and filling
-Turn the cap slowly and very carefully in a
counter-clockwise direction while applying
light, downward pressure on the top of
the cap .
- To avoid being burned, do not spill anti­
freeze or coolant on the exhaust system or hot engine parts. Under certain condi ­
tions, the ethylene glycol in engine cool­
ant can catch fire .
- Antifreeze is poisonous. Always store anti­
freeze in its original container and well out of the reach of children .
- If you drain the coolant, it must be caught
and safely stored in a proper container
clearly marked "poison".
CD Note
-Coolant pollutes the environment and could
cause an engine fire . Excess coolant will be
forced out through the pressure relief valve
in the cap when the engine becomes hot.
-If, in an emergency, only water can be add­
ed, the correct ratio between water and an­
tifreeze
¢ page 161 must be restored as
soon as possible.
@ For the sake of the environment
Drained coolant should not be reused. Always
dispose of used coolant while observing all
environmental regulations.
Brake fluid
Have the brake fluid changed by an experienced
technician.
Brake fluid absorbs moisture from the air. If the
water content in the brake fluid is too high, cor­
rosion in the brake system may result after a peri­
od of time. The boiling point of the brake fluid
will also decrease considerably and decrease
braking performance.
Therefore, the brake fluid must be changed
every
two years.
Always use new brake fluid which con­
forms to Federal Motor Vehicle Standard "FMVSS
116 DOT 4".
164
Brake fluid is replaced according to the Audi
maintenance service schedule . Your authorized
Audi dealer is equipped with the necessary spe­
cial tools and replacement parts, has the neces­
sary expertise, and can dispose of the used fluid .
A WARNING
-Brake fluid is poisonous . It must be stored
only in the closed original container out of
the reach of children!
- Brake failure can result from old or inappro­ priate brake fluid. Observe these precau­
tions:
- Use only brake fluid that meets SAE speci­
fication
J 1703 and conforms to Federal
Motor Vehicle Standard
116. Always check
with your authorized Audi dealer to make
sure you are using the correct brake fluid .
The correct type of brake fluid is also indi­ cated on the brake fluid reservoir.
- The brake fluid must be new . Heavy use of
the brakes can cause a vapor lock if the brake fluid is left in the system too long.
This can seriously affect the efficiency
of
the brakes as well as your safety . This
could result in an accident.
CD Note
Brake fluid will damage the paint of your vehi­
cle.
@ For the sake of the environment
Because of the problem of proper disposal of
brake fluid as well as the special tools re­
quired and the necessary expertise, we rec­
ommend that you have the brake fluid
changed by your authorized Audi dealer.
Battery

Tires and wheels
Tires
General notes
Tires may be the least appreciat­
ed and most abused parts of a
motor vehicle.
Tires may be the least appreciated
and most abused parts of a motor
veh ic le . Tires are, however, one of
the most important parts of ave ­
hicle, particularly considering the
comparatively small patch of rub­
ber on each tire that assu res that
all-important contact between
you, your vehicle and the road .
Maintain ing the correct t ire pres­
sure, making sure that your vehi­
c le and its tires do not have to
carry more weight than they can
safe ly handle, avoiding damage
from road hazards and regularly inspecting tires for damage in­
c luding cuts, slashes i rregular
wear and overall condition are the most important th ings that you
can do to help avo id sudden tire
failure including tread separation
and blowouts.
Avoiding damage
~ If you have to dr ive over a curb or ":
~ similar obstacle, drive very s lowly

Tir es a nd whe els
and as close as possible at a right
ang le to the curb.
Always keep chemicals including
grease, oil, gasoline and brake
fluid off the tires. Inspect the tires regularly fo r
damage (cuts, cracks or blisters ,
etc.) . Remove any foreign bodies
embedded in the treads.
Storing tires
Mark tires when you remove them
to indicate the direction of rota­
tion. This ensures you to be able
to mount them correctly when
you reinstall them.
When removed, the w heels or
tires sho uld be stored in a coo l,
dry and preferably dark place.
Store tires in a vertical position if
they are not mounted on rims, in
a horizon tal position if they are
mounted on rims .
New tires
New tires have to be broken in

technically referred to as the vehi­
cle's
Gross Vehicle We ight Rating
("GVWR") .
The "GVWR" includes the weight
of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids plus maximum load. The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci ­
ty") with an assumed weight of
150 lbs. (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any
luggage in the vehicle.
The
Gross Axle Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles .
The Gross Vehicle Weight Rating and the Gross Axle Weight Rating
are listed on the safety compli­
ance sticker label located on the
driver's side B-pillar. Your Audi
has 2 seating positions . Each
seating position has a safety belt
¢ page 95, Safety belts.
The fact that there is an upper
limit to your vehicle's Gross Vehi ­
cle Weight Rating means that the
total weight of whatever is being
Tires and wheels
carried in the vehicle is limited.
The more passengers in the vehi­
cle or passengers who are heavier
than the standard weights as­
sumed mean that less weight can
be carried as luggage.
The tire pressure label on your
Audi also lists the maximum com ­
bined weight of all of the occu­
pants and luggage or other cargo
that the vehicle can carry. For the location of the label¢
page 176,
fig. 147.
A WARNING
-
Overloading a vehicle 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 in­
crease 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 •

Tires and wheels
All-wheel drive
Only the wheel/tire sizes specified
by the manufacturer may be used
on vehicles with all-wheel drive. For details see¢
page 139.
A WARNING
Sudden tire failure can lead to
loss of control, a crash and seri­
ous personal injury!
-Never drive a vehicle when the tread on any tire is worn down
to the wear indicators.
-Worn tires are a safety hazard,
they do not grip well on wet
roads and increase your risk of
"hydroplaning" and loss of
control.
-Always keep chemicals that can cause tire damage, such
as grease, oil, gasoline and brake fluid away from tires.
-Tires age even if they are not
being used and can fail sud­
denly, especially at high
speeds. Tires that are more
than 6 years old can only be
used in an emergency and
then with special care and at lower speeds.
-Never mount used tires on
your vehicle if you are not sure
of their "previous history." Old
186
used tires may have been
damaged even though the
damage cannot be seen that
can lead to sudden tire failure
and loss of vehicle control.
New tires and replacing tires
