When adding fluids, a lways make sure that they are poured into the
proper container or filler opening, otherwise serious damage to
veh icle systems w ill occur.
<£' For the sake of the environment
T o de tect leaks in time, inspect the veh icle floo r pa n from u nder neat h
regu larly. If you see spots from oil or other vehicle fluids, have your

• 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 added, the correct ratio
between water a nd antifreeze ::::>
page 281 must be restored as soon
as possible.
ci> For the sake of the environment
Drained coolant should not be reused. Always dispose of used coolant
wh ile observ ing all environmental regulations.•
Radiator fan
The radiator fan switches on automatically by itself.
The radiator fan is driven by the engine v ia the V-belt. The viscous
clutch regulates the speed of the fan according to the temperature of
t he coo lant.
An auxiliary electr ic radiator fan* sw itches on and off depending on
coolant temperature and other vehicle operating conditions.
After you switch the engine off, the auxiliary fan can cont inue running
for up to 10 minutes- even with the ignition off. It can even switch on
again later by itse lf::::>
/1 , if
• the temperature of the engine coolant rises due to the heat build­
up from the engine in the engine compartment, or
• the engine compartment heats up because the veh icle is parked in
intense sunlight.
& WARNING
• To reduce the risk of personal injury never touch the radiator
fan.
/1 WARNING (continued)
• 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 automatically when the
engine coolant reaches a certain temperature and will continue to
run until the coolant temperature drops .•
Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a quick glance.
Fig . 209 Engine
co mpartm ent : Brake
fluid reservoir
Before you check anything in the engine compartment,
always read and heed all WARNINGS=> & in "Working in
the engine compartment" on
page 275.
-Read the brake fluid level from the brake fluid reservoir
=> fig. 209. The brake fluid level must be between the
"MIN" and "MAX" markings.
The brake fluid reservoir is located at the rear partition of the engine
compartment on the left side=>
page 276. .,

___________________________________________ C_ h_e _c _k_ i_n ~g_ a_n_ d_ f_ i_ll _i_n _g __ _
The fluid level may drop slightly after some time due to the auto­
matic adjustment of the brake pads. This is not cause for alarm.
If the brake flu id level falls considerably below the "MIN " mark, the
brake warning/indicator light (U.S. models:
BRAKE , Canadian mode ls:
{(j)) ) will come on=> page 18 and=> page 33. Do not continue to
ope rate the vehicle. The complete brake system should be thorough ly
checked by an authorized Audi dealer or qualified workshop and the
cause corrected. If the brake fluid level is too low, the brake
wa rning/ind icator light will illuminate. Contact an authorized Aud i
dealer
immediately .
[I] Tips
The brake fluid reservoir is located undernea th the cover. •
Changing brake fluid
Hove the broke fluid changed by on experienced techni­
Clon.
Brake fluid absorbs moisture from the air. If the water content in the
brake fl uid 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 flu id must be changed
every two years. Always
use new brake fluid which conforms to Federal Motor Vehicle Stan­
dard "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 authorized
Audi dealer. Your dealer has the correct tools, the right brake fluid
and the know-how to do this for you .
& WARNING
• Brake fluid is poi sonous. It must be stored only in the closed
original container out of the reach of children!
Safety first
& WARNING (continued )
• Brake failure can result from old or inappropriate brake fluid.
Observe these precautions:
-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 efficiency of the brakes as
well as your safety. This could result in an accident .
0 Note
Brake fluid will damage the paint of your vehicle.
ffi For the sake of the environment
Because of the prob lem of proper disposal of brake fluid as well as
th e special tools required and the necessary expertise, we recom­
mend that you have the brake fluid changed by your author ized Audi
dealer. •
Battery
General information
Under normal operating conditions, the battery in your Audi does not
need any maintenance . With high outside temperatures or long daily
drives we recommend that you have the electro lyte level checked by
an authorized Audi dealer or qualified workshop . The electrolyte leve l
should also be checked each t ime the battery is charged=> page 288.

Tire pressure
Incorrect tire pressure causes premature wea r a nd can cause sudden
t ire blow-out. For this reason, ti re p ressure must be checked at least
once a month ~
page 297.
Driving style
Driving fast around curves, heavy acce le ra tion and hard brak ing
increase tire wear .
Rotating tires for more even wear
For all four tires on your veh icle to have the same service life, we
re commend that the fron t and re a r tires are rotate d according to the
tire manufact urer's suggested tire rotation interva ls . Please
remember the fo llow ing:
• Tir e rotat ion inte rvals may differ from t he ve hicl e service intervals
outlined in your Maintenance and War ranty Booklet .
• T he longer one tire is used in one location on the veh icle, the more
it wears at certa in points; therefore, we recommend that you follow
t he t ire m anufac ture r's suggested tire rotation in terva ls.
• V ehicles with front-whee l drive expe rience mo re tread wea r on t he
fron t wheels compa red to all-whee l drive (quattro
® ).
• Please rotate tires as s hown ~fig. 215.
• Extra care must be taken when rotating d irection-specific tires
~ page 321.
Wheel balancing
The w heels on new vehicles are balanced. Howeve r, va rious sit uat io ns
dur ing eve ryday dr iv ing can cause them to become unbalanced,
re su lt ing in v ibr ations yo u can usually fee l throug h the steering
wheel.
Unbalanced wheels must be rebalanced to avoid excessive wea r on
steeri ng, suspension and t ires . A wheel must also be rebalanced
w hen a new tire is installed.
Incorrect wheel alignment
Incorrec t whee l alignment can ca use excessive tire wear, impai ring
t he sa fety of the veh icle . If tires show excess ive wear, have the wheel
alignment checked by an authorized A udi dealer or qualified wo rk­
shop .
All wheel drive
Vehicles w ith q uattro ® must always have ti res of the same size,
const ructio n and trea d type. For details see~
page 242 .
& WARNING
Sudden tire failure can lead to loss of control , a crash and serious
personal injury!
• Never drive a vehicle when the tread on any tire is worn down
to the wea r ind icato rs.
• Worn tire s are a safety hazard, they do not grip well on wet
roads and in crease your risk of "hydroplaning" and lo ss 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 tire s on your vehicle if you are not sure of
their "previous history ." Old 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. •
