A WARNING
-Always observe the warnings in
9 page 206, before opening the hood
and checking the brake fluid.
- Driving with low brake fluid is a safety
hazard. Stop the car and get professional
assista nee.
- If the. (USA models)/ . (Canada
models) brake system indicator light
turns on together with the ABS and ESC indicator lights, the ABS/ESC regulating

Audi dealer or other qualified workshop and have the malfunction corrected.
- If the brake warning/indicator light does
not go o ut afte r a few seconds and the
park ing brake is released, or lights up
wh ile 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 th e nearest
authorized Aud i dealer o r qualified wo rk­
shop and have the bra ke system inspect­
ed.
- Always keep in m ind that afte r several
brake applicat ions, yo u w ill need g reater
pressure on the brake peda l to s top your
vehicle. Do not re ly on strained brakes to
respond with maxim um stopp ing power
in critical situations. You must a llow for
increased brak ing distances. The extra
distance used up by fad ing brakes could
lead to an acc ident .

At higher speeds and with the windshield wip ­
ers turned on, the brake pads press against
the brake rotors for a short amount of time.
This occurs at regular intervals without the
driver noticing and provides for better brake
response time under wet conditions.
The effectiveness of the brakes can be reduced
when the vehicle is dr iven on a salt-covered
road and the brakes are not used . Likewise,
you clean
off accumulated sa lt coating from
brake discs and pads with a few cautious ap­
plications of the brake~&. .
Cor ro sion
There may be a tendency for dirt to build up
on the brake pads and corrosion to form on
the discs if the car is not dr iven regularly or
only for short trips with little use of the
brakes .
If the brakes are not used frequently, or if cor­
rosion has formed on the discs, it is advisable
to clean
off the pads and discs by brak ing
firm ly a few times from a moderately h igh
speed
¢ .Li). .
Fa ults in the brake system
If you should notice a sudden increase in
brake pedal travel, then one of the two brake
circu its may have failed~&,. .
Low brake flu id le vel
Malfunct ions can occur in the brake system if
the brake fluid level is too low . T he brake fluid
level is monitored electronically .
Brake boo ste r
The brake booster increases the pressure th at
you generate w ith the bra ke pedal. It works
only when the engine is running

Brake lining w ear statu s
Brake lining wea r may be c hecked by vis ual in­
spection of the condition of the brake pads
through the openings in the whee l. If neces ­
sary, the whee l may be removed for this in­
spection

A WARNING
-New brake pads don't have the best stop­
ping power and must be "b roken-in" dur­
ing the initial 100 to 150 miles (150 to
200 kilometers) of normal c ity dr iving .
You can compensate for this by pressing the brake pedal more firmly. This also
applies la ter when new pads are instal­
led.
- You should perform braking m aneuvers
for the purpose of cleaning the brake
system only if road conditions permit .
Other road users must not be put at risk -
you may ca use an accident!
- Before descend ing a steep grade, reduce
speed and sh ift transmission into a lower
gea r or lower dr iving range. Do not ride
the brakes or hold the pedal down too
long or too often . Th is could cause the
brakes to get hot and diminish braking
efficiency.
- Do not "ride the brakes" by rest ing your
foot on the pedal when you do not intend
to b rake. This may cause the brakes to
overheat, p remature wear and increased
s topping distance.
- Unde r ce rtain cl imatic and ope rat ing
conditions such as passing thro ugh wa ­
ter, dr iv ing in heavy rain o r after washing
the vehicle, the effectiveness of the
brakes can be reduced. In winter, ice can
accumu late on the brake pads, linings,
discs and drums. Carefully app ly brakes
for a test. Brakes w ill dry and ice coat­
ings w ill be cleaned
off after a few care­
fu l brake applicat ions .
- Driving for an extended period of time o n
salt-cove red roads without using your
brakes can a lso affect braking efficiency.
C lean
off accum ulated salt coa ting from
bra ke disc s and pad s wi th a few ca reful
bra ke applica tions.
- If you damage the front spoiler, or if you
install a diffe rent spoiler, be sure the air

192 Trailer towing
Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a trai ler, p lease remember
that the additional load will affect durability,
economy and performance .
Trailer towing not on ly places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
For this reason, always fo llow the operating
and driving instructions provided and use
common sense.
Technical requirements
Trailer hitch Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suita­
ble for your vehicle and trailer and must be
mounted securely on the veh icle's chassis at a
technically sound location. Use only a trailer
hitch with a removable ball mount. Always
check with the trailer hitch manufacturer to
make sure that you are using the correct
hitch.
Do not use a bumper hitch.
The hitch must be installed in such a way that
it does not interfere with the impact-absorb­
ing bumper system . No modifications should
be made to the vehicle exhaust and brake sys­
tems . From time to time, check that all hitch
mounting bolts remain securely fastened.
When you are not towing a trailer, remove the
trailer hitch ball mount. This prevents the
hitch from causing damage should your vehi­
cle be struck from behind
¢ A.
Trailer brakes
If your tra iler is equipped with a braking sys­
tem, check to be sure that it conforms to a ll
regulations . The trailer
hydraulic brake system must not be
direct ly connected to the vehicle's hydraulic
brake system
~ A.
Safety chains
Always use safety chains between your vehicle
and the tra ile r.
Trailer lights
T railer lights must meet all regulations. Be
sure to check w ith your authorized Audi dealer
for correct wiring, sw itches, and relays.
Mirrors
If you are unable to see the traffic behind you
using the regular outside mirrors, then you
must install extended mirrors . It is important
that you
always have clear vis io n to the rear.
,8. WARNING
- If a trailer has electrical brakes please
note that these brakes are not activated
by the factory-fitted control unit -risk of
accident!
- Afte r removing the trailer hitch, do not
store it in your vehicle. In case of sudden
braking, the hitch could fly forward and
injure you or yo ur passengers.
Operating instructions
Maximum trailer weight
-
A trailer for your vehicle is limited to a typical
class 1 or class 2 tra iler.
Trailer load distribution Be sure the load in the trailer is held secure ly
in place to prevent it from shifting forward,
backward or sideways.
Never allow a passenger to ride in a trailer
¢ A in Driving instructions on page 193.
Engine cooling system
T owing a trailer makes the engine work hard ­
er. It is important that the cooling system's
performance is up to the additional load.
Make sure that the cooling system has enough
fluid . .,..

Before you check anything in the engine com­
partment,
always read and heed all WARN·
INGS ¢ .&._ in Working in the engine compart­
ment on page 206 .
.. Read the brake fluid level from the brake
fluid reservoir ¢
fig. 179 , ¢ page 208,
fig. 175.
The brake fluid level must be be ·
tween the "MIN" and
"MAX" markings.
The brake fluid reservoir is located at the rear
partition of the engine compartment on the
left side ¢
page 208 .
The fluid level may drop slightly after some
time due to the automatic adjustment of the
brake pads . This is not cause for alarm.
If the brake fluid level falls
considerably be­
low the "MIN" mark, the brake warning/indi­
cator light (U.S. models: ., Canadian mod­
els: .) will come on¢
page 15. Do not con­
tinue to operate the vehicle . The complete
brake system should be thoroughly checked
by an authorized Audi dealer or qualified
workshop and the cause corrected.
If the
brake fluid level is too low, the brake warning/
indicator light will illuminate. Contact an au­
thorized Audi dealer
immediately .
@ Tips
The brake fluid reservoir is located under­
neath the cover.
Changing brake fluid
Have the brake fluid changed by an experi­
enced technician .
Brake fluid absorbs moisture from the air. If
t he water content in the brake fluid is too
high, corrosion in the brake system may result
after a period 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 conforms to Federal Motor Vehicle
Standard "FMVSS 116 DOT 4".
The brake fluid reservoir can be difficult to reach, therefore, we recommend that you
have the brake fluid changed by your author­
ized
Audi dealer. Your dealer has the correct
tools, the right brake fluid and the know-how
to do this for you .
A WARNING
- Brake fluid is poisonous. It must be stor­
ed only in the closed original container
out of the reach of children!
- Brake failure can result from old or inap­
propriate brake fluid. Observe these pre­
cautions:
- Use only brake fluid that meets SAE
specification
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 indicated 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 effi­
ciency of the brakes as well as your
safety. This could result in an accident.
(D Note
Brake fluid will damage the paint of your
vehicle.

@ For the sake of the environment
Because of the pr oblem of proper d isposa l
of brake flu id as we ll as the special tools
requ ired and the necessary expert ise, we
recommend that you have the brake fluid
changed by your author ized Audi dealer .
Battery
General information
Under normal operating conditions, the bat­
tery in your Audi does not need any mainte ­
nance. With
high outside temperatures or
long daily dr ives we recommend that you have
the electro lyte level checked by an authorized
Aud i dealer or qualified workshop . The elec­
trolyte leve l should also be checked each time
the battery is charged ¢
page 219.
Have the battery checked when you take your
ve hicle in for service . Yo u are well adv ised to
replace a battery that is older than 5 yea rs .
W ith certa in types of a irbag deployment, t he
b attery is d isconnected from the vehicle elec­
tr ica l system for safety reasons¢.&.
in Re ­
pair, care and disposal of the airbags on

Disconnecting the battery terminals
Some vehicle functions (power w indow regu­
lators , for example) are lost if the battery ter­
m inals a re d isconnected. These func tions have
to be re lea rned after the batte ry term inals a re

Incorrect wheel alignment
Incorrect wheel alignment can cause exces­
sive tire wear, impairing the safety of the vehi­
cle. If tires show excessive wear, have the
wheel alignment checked by an authorized
Audi dealer or qualified workshop .
All wheel drive
Vehicles with quattro must always have tires
of the same size, construction and tread type.
For details see~
page 184 .
.8_ WARNING
Sudden tire failure can lead to loss of con­
trol, a crash and serious personal injury!
- Never drive a vehicle when the tread on
any tire is worn down to the wear indica­
tors.
- Worn tires are a safety hazard, they do
not grip well on wet roads and increase
your risk of "hydroplaning" and toss 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 suddenly, 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 histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
