.... N
0 I-­co .... .... Operating noi se
Noises may occur when braking depend ing on the
speed, braking force and outside conditions such
as temperature and humidity.
Eff ect of wat er and road salt
In ce rtain situations, for example after dr iving
through water, in heavy ra in, afte r ove rnig ht con­
densat io n or after washing your car, the braking
effect can be reduced by moisture or ice on the
brake rotors and brake pads. The brakes must be
dried first with a few careful brake applications .
At highe r speeds and with the windsh ie ld wipers
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 driven on a salt-covered road and the brakes are not used . Likewise, you clean
off accumu lated salt coating from brake discs
and pads with a few cautious applications of the
brake ~,&. .
Cor ro sion
There may be a tendency for dirt to b uild up on
the brake pads and corros ion to form on the discs
if the car is not driven regularly or only for short
tr ips with little use of the brakes .
If the brakes are not used frequently, or if corro­
sion has formed on the discs, it is adv isable to
clean off the pads and discs by braking firmly a
few t imes from a moderately high speed
c:> ,&. .
Fa ults 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 failed
c:> ,&. .
Low brak e fluid level
M alfunct ions can occur in the brake system if the
b rake fluid leve l is too low . The brake fluid level
is monitored e lectronically .
Intelligent Technology
Brake booster
The brake boos ter increases the press ure that
you generate with the brake peda l.
It works only
when the eng ine is running
. c:> .&.
Brake lining wear status
B rake lining wea r may be chec ked by visua l in­
spe ct ion of the condi tion of the brake pads
t hr ough the openings in the wheel. If necessary,
the wheel may be removed for this inspection
c:> page 2 26, Replacing wheels .
_8 WARNING "'---
-New brake pads don't have the best stop­
ping power and m ust be "broken-in" during
the initial 250 miles (400 kilometers). You can compensate for this by p ressing the
brake pedal more firmly . This also app lies
later when new pads are installed.
-
- You shou ld pe rform braking maneuvers for
the purpose of cleaning the brake system
only i f road condit ions pe rmit . Other road
users m ust not be put at r is k -you may
cause an ac ciden t!
- Before descending a s teep g rade , reduce
speed and sh ift tr ansmi ssion into a lower
gear or lower dr iving range. Do not r ide the
brakes or hold the pedal down too long or
too often. This co uld cause the brakes to get
hot and dimin ish braking eff ic iency.
- Do not "ride the bra kes" by resting your foot
on the pedal when you do not intend to brake. This may cause the brakes to over­
heat, premature wear and increased stop­
ping distance.
- Unde r ce rtain climatic and operating condi­
tions such as passing through water, driving in heavy rain or after wash ing the veh icle,
the effectiveness o f the brakes ca n be re­
duced. In winter, ice can accumu late on the
brake pads, lin ings , d is c s and dr ums . Care­
fu lly apply br akes for a test. Brakes will dry
and ice coatings will be cleaned off after a
few careful bra ke applications .
- Driving for an extended period of time on
salt -covered roads without using your
brakes can also affect braking eff iciency .

0 I­co .... .... Trailer mode Driving with a trailer
General information
Your Audi was designed primarily for passenger
transportation .
If you plan to tow a trailer, please remember that
the additional load will affect durability, econo­ my and performance.
T railer towing not only places more stress on the
vehicle, it also calls for more concentration from
the driver.
For this reason, always follow 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 suitable
for your vehicle and trailer and must be mounted
securely on the vehicle's chassis at a technically
sound
location . Use only a trailer hitch with a re­
movable ball mount . Always check with the trail­
er 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 -absorbing
bumper system . No modifications should be
made to the vehicle exhaust and brake systems .
From time to time, check that all hitch mounting
bo lts remain securely fastened.
When you are not towing a trailer,
remove the
tra iler hitch ball mount . This prevents the hitch
from causing damage should your vehicle be
struck from beh ind ¢
,&. .
Trailer brakes
If your trailer is equipped with a braking system,
check to be sure that it conforms to all regula­
tions .
Trailer mode
The trailer hydraulic brake system must not be
directly connected to the vehicle's hydraulic
brake system ¢.&. .
Safety chains
Always use safety chains between your vehicle
and the trailer.
Trailer lights
T ra iler lights must meet all regulations . Be sure
to check with your author ized Audi dealer for cor­
rect wiring, switches, and relays.
Mirrors
If you are unable to see the traffic behind you us­
ing the regular outside mirrors, then you
must in­
stall extended mirrors. It is important that you
always have clear vision 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!
- After removing the trailer hitch, do not store it in your vehicle. In case of sudden
braking, the hitch could fly forward and in­
jure you or your passengers.
Operating instructions
Maximum trailer weight
A trailer for your vehicle is limited to a typical
class 1 or class 2 trailer.
Trailer load distribution
Be sure the load in the trailer is held securely in
place to prevent it from shifting forward, back­
ward or sideways.
Never allow a passenger to ride in a trailer¢.&.
in Driving instructions on page 182.
Engine cooling system
Towing a trailer makes the engine work harder . It
is important that the cooling system's perform ­
ance is up to the additional load . Make sure that
the cooling system has enough fluid. .,..

-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".
(D Note
-Do not add coolant if the expansion tank is
empty . Air could enter the cooling system
and damage the engine.
If this is the case,
do not continue driving. Seek professional
assistance.
- 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 c::>
page 196 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.
Radiator fan
The radiator fan switches on automatically by it­
self.
The radiator fan is driven by the engine via the V­
belt . The viscous clutch regulates the speed of
the fan according to the temperature of the cool­
ant.
An auxiliary electric radiator fan* switches on and
off depending on coolant temperature and other
vehicle operating conditions.
After you switch the engine off, the auxiliary fan
can continue running for up to 10 minutes -even

with the ignition off. It can even switch on again
later by itself c::>
&, if
- the temperature of the engine coolant rises due
to the heat build-up from the engine in the en­
gine compartment, or
- the engine compartment heats up because the
vehicle is parked in intense sunlight.
A WARNING
-To reduce the risk of personal injury never
touch the radiator fan.
- The auxiliary electric fan is temperature
controlled and can switch on suddenly even
when the engine is not running.
- The auxiliary radiator fan switches on auto­
matically when the engine coolant reaches a
certain temperature and will continue to run
until the coolant temperature drops.

Contact a n author ized Audi dealer
immediately .
{D) Tips
The brake fluid reservoir is located under­
neath the cover .
Changing brake fluid
Have the brake fluid changed by an experienced
technician .
Brake fluid absorbs mo isture from the air. If the
water content in the b rake fluid is too high, cor­
rosion in the brake system may resu lt afte r ape ­
riod of t ime. The boiling poi nt of the brake flu id
will also decrease cons iderably and decrease
b raking perfo rman ce.
Therefore, the brake fluid must be changed
every
two year s.
Always use new brake fluid wh ic h con­
forms to Fede ral Motor Veh icle Standard "FMVSS
1 16 DO T 4".
The brake fluid reservoir can be diff icult to reach,
therefore, we recommend that yo u have the
brake fl uid changed by yo ur autho rized
Audi
dealer .
Your dealer has t he corre ct tools, t he
right brake fluid and the know-how to do this for
you.
A WARNING
- Brake fluid is poisonous. It must be stored
only in the closed orig inal container out of
the reach of chi ldren!
200
- Bra ke fa ilure ca n result from old or inapp ro­
priate brake fluid . Observe these precau­
tions:
- Use only brake fluid t hat meets SA E speci­
fi ca ti on
J 170 3 and con forms to Federa l
Motor Ve hicle Standard 116 . Always check
wi th yo ur autho rized Audi dea le r to make
s ur e yo u are using the correct brake fluid .
The correct type of brake flu id is also ind i­
cated on the b rake fluid reservo ir .
- The brake fluid m ust be new . Heavy use of
the brakes can cause a vapo r lock if the
brake fluid is left in the system too long .
This can se riously affect the efficiency of
the b rakes as well as your safety . This
could resu lt in an accident .
(D Note
Brake fluid will damage the paint of your veh i­
cle.
