Engine oil
Engine oil specifications
The engine in your Audi needs the right kind
of oil.
The engine in your Audi is a sophisticated
powerplant that was built to exacting spec ifi­
cations . Th is eng ine needs the right k ind of
engine oil that meets specifications regardi ng
quality and viscosity so that it can run
smooth ly and reliab ly. Choosing the right o il
and changing oil within the time and mileage
intervals printed in your vehicle's Warranty
&
Maintenance booklet matters a lot more to­
day than it did years ago . Audi has deve loped
a spec ia l quality standard for engine oil that
will help assure that your vehicle's engine w ill
get the lubrication it needs for proper opera­
tion.
Modern engine lubrication has taken a quan ­
tum leap in the last few years. Many synthetic

-Antifreeze is poisonous . Always store an­
t ifreeze in its or iginal container and well
out of the reach of children.
- If you drain the coolant, it must be
caught and safely stored in a proper con­
tainer clearly marked "poison".
(D Note
- Coolant pollutes the environment and
could cause an engine fire. Excess coo l­
ant will be forced out through the pres­
sure re lief va lve in the cap when the en­
gine becomes hot.
- If, in an emergency, only water can be
added, the correct ratio between water
and antifreeze ¢
page 264 must be re­
stored as soon as possib le.
@ For the sake of the environment
Drained coolant should not be reused. Al­
ways dispose of used coolant while observ­ ing all environmental regulations .
Radiator fan
The radiator fan switches on automatically by
itself
The radiator fan is driven by the engine via the
V-belt . The viscous clutch regulates the speed
of the fan accord ing to the temperature of the
coolant .
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 auxilia ry
fan can continue running for up to 10 minutes
- even with the ignition off. It can even switch
on again later by itself¢& , 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 hea ts up because
the vehicle is parked in intense sunlight .
Checking and fillin g 267
A WARNING
-To reduce the risk of personal injury nev­
er touch the rad iator 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 au­
tomatically when the engine coolant reaches a certain temperature and will
continue to run until the coo lant temper­
ature drops.

Before you check anything in the eng ine com­
partment ,
always read and heed all WARN­
INGS ¢ A in Working in the engine compart­
ment on page 257.
.,. Read the brake fluid level from the brake
fluid reservoir ¢
fig. 246, ¢ page 259,
fig. 241.
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 eng ine compartment on the
left side ¢
page 259.
The fluid level may drop slightly after some
time due to the automatic adjustment of the
brake pads. This is not cause for alarm. ..,_

268 Check ing and filling
If the brake fluid level falls considerably be­
low the "MIN" mark, the brake warning/indi­
cator light (U .S . mode ls:
1111 , Canadian
models: .) will come on
<::> page 19 and
<::> page 32. Do not continue to operate the ve­
h icle . The complete brake system should be
thoroughly checked by an authorized Aud i
dea ler or qualified workshop and the cause
corrected. If the brake fluid level is too low,
the brake warning/indicator light will illum i­
nate . Contact an authorized Aud i dealer
im­
m ediatel y.
@ Tips
The brake fluid rese rvoir is located unde r­
neath the cove r.
Changing brake fluid
Hove the broke fluid changed by on experi­
enced technician.
Brake fluid absorbs moisture from the a ir . If
the water content in the brake fluid is too
h igh , corrosion in the brake system may result
after a per iod of t ime. The bo iling po int of the
brake fluid wi ll also decrease considerably and
decrease braking performance.
Therefore, the brake flu id must be changed
e ver y tw o year s. Always use new b rake fluid
which conforms to Federal Motor Vehicle
Standard "FMVSS 1 16 DO T 4".
The brake flu id reservo ir can be difficult to
reach, therefore, we recommend that yo u
have the brake f luid changed by you r author­
ized
Audi dea ler. Your dea ler has the correct
too ls, 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 i n the closed orig inal container
o ut of the reach of children!
- Brake fa ilure can result from old or inap­
propriate b rake fluid. Observe these pre­
caut ions: -
Use only brake fluid that meets SAE
specification
J 1703 and conforms to
Federa l 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 f lu id is also ind icated on the
brake flu id reservoir.
- T he brake fluid must be new. Heavy use
of the bra kes ca n cau se a vapo r lock if
the b rake fluid is left in the system too
l ong . This can seriously affect the effi ­
c iency of the brakes as well as your
safety. This co uld resu lt in an accident.
(D Note
Bra ke fluid will damage the paint of you r
vehicle .
(® For the sake of the environment
Because of the p rob lem of p roper disposal
of b ra ke fluid as well as the spec ial too ls
r equired and the necessary expertise, we
re commend that yo u have the brake fluid
changed by yo ur authorized Aud i dea ler.
Battery
General information
U nder normal ope rat ing cond itions, the bat­
tery in yo ur Audi does not need any ma inte­
nance. With
high o utside tempe ra tur es or
l ong dai ly drives we recommend that you have
the e lectrolyte level checked by an authorized
Audi dealer or qualif ied workshop. The elec­
trolyte level should also be checked each time
the battery is charged
<::> page 2 70.
Have the battery checked when yo u take your
vehicle in for service. You are well advised to replace a battery that is o lder than 5 years .
With certain types of airbag deployment, the batte ry is disconnected from the veh icle elec­
trical system for safety reasons¢.&

Tires and wheels
Tires
General notes
Tires may be the least appreciated and most
abused parts of a motor vehicle .
Tires may be the least appreciated and most
abused parts of a motor vehicle . T ires are,
however, one of the most important parts of a
vehicle, particularly considering the compara­
tively small patch of rubber on eac h tire that
assures that a ll- important contact between
you, you r vehicle and the road.
Maintaining the correct tire pressure, mak ing
sure that your vehicle and its tires do not have
to carry mo re weight than they can safely han­
d le, avoiding damage from road hazards and
r eg ularly inspec ting t ires for damage i nclud­
ing cuts, slashes irregu la r wear and ove rall
condition are the most important things that
you can do to he lp avoid sudden tire failure in­
cluding tread separat ion and blowouts.
Avoiding damage If you have to d rive over a curb or similar ob­
stacle, drive very slow ly and as close as possi ­
b le at a right angle to the curb.
A lways keep chemicals includ ing grease, o il ,
gasoline and brake fluid off the t ires .
I nspect the t ires regularly for damage (cuts,
cracks or b listers, etc.). Remove any fo reign
bod ies embedde d in the treads.
Storing tires Mark tires when you remove them to indicate
the direction of rotation . T his ensures you to
be ab le to mount them correctly when you re­
i nstall them .
When removed, the whee ls or t ires should be
sto red in a cool, d ry and preferably dark place .
Store tires in a vertical pos ition if they are not
mounted on rims, in a horizontal pos it ion if
they are mounted on rims .
Tires an d wheel s 273
New tires
New tir es have to be broken in ¢ & .
The tread depth of new t ires may vary, accord­
ing to the type a nd make of t ire and the tread
pa tte rn.
Hidden damage
Damage to tires and r ims is ofte n not readily
visible . If you notice unusual v ib rat io n or the
vehicle p ulls to one s ide, th is may ind icate
that one of the t ires has been damaged . T he
ti res m ust be chec ked immed iate ly by an au­
thorized Audi dea le r or q ua lified wor kshop .
Unidirectional tires
A un idirectional tire can be identified by ar­
rows on the s idewa ll, that po int in the direc­
tion the t ire is designed to rotate. You mus t
f ol low the specified di rection o f rotation . T his
is necessary so that these tires can develop
their optimum characteristics regarding grip, road noise, wear and hydrop laning resistance.
For more information ¢
page 301.
A WARNING
New tires or t ires that are o ld, worn or
damaged cannot provide maximum con­
trol and braking ability .
-
-New tires tend to be slippery and must
be broken in. To reduce the r isk of losing
control, a co llision and ser ious personal
in ju ries, d rive with special ca re fo r the
fi rst 350 m iles ( 560 km).
- Driving with worn or damaged tires can
lead to loss of control, sudden tire fail­
ure, including a blowout and sudden de­
fl ation, c ras hes and se riou s personal in­
juries . Have wo rn or damaged t ires re­
placed immediate ly.
- Ti res age even if they are not being used
and can fai l sudden ly, especially at hig h
spee ds. Tires that are more than 6 years
old can only be used in an emergency
and then w ith special care and at low
speed.

284 Tires and wheels
All-wheel drive
Vehicles with quattro must always have tires
of the same size , construction and tread type.
For details see Qpage 228.
~ WARNING
Sudden tire failure can lead to loss of con­
trol, a crash and serious persona l 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 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 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 a re 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.
New tires and replacing tires and wheels
New tires and wheels have to be broken in .
