ri zed Audi deal er or a qualified s erv ic e sta tion.
Before you check anything in the engine compartment, always read
and heed all WARNINGS=>
& in "Working in the engine compart­
ment" on
page 275.
Th e en gine oi l must be changed a ccording to the i nte rvals spe cifi ed i n
your Warranty
& Maintenance booklet. This is very important because
the lubricating prope rties of oil diminis h gradually during normal
veh icle use.
Under some circumstances the engine o il should be changed more
frequently . Change o il more often if yo u drive most ly sho rt dista nces,
operate the vehicle in dusty areas or under predom inant ly stop-and­
go tra ffic condi tions , or have your vehi cle where tempera tures rem ain
be low freezing for extended per iods.
Detergent ad ditives in the oi l will make fresh oil look dark after the
eng ine has bee n ru nning fo r a short t ime . This is normal a nd is not a
reason to change the oil mo re often than recommen ded .
B eca u se of the prob lem of pro per disposal, along with the s peci al
too ls and necessary expertise required, we strong ly recommend that
you have your o il changed by a n autho rized
Audi dealer or a qualified
serv ice stat io n.
If you choo se to change your oil yourself , please note the following
i m po rtant informat ion:
& WARNING
To reduce the risk of personal injury if you must change the engine

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. •
