Working in the engine compartment
Be especially careful whenever you work in the engine compartment!
Whenever you must perform any work in the
engine compartment, for example checking
and filling the different fluids, there is a risk
of injury, burns and accidents. To prevent per
sonal injury always observe the following
WARNINGS. The engine compartment of any
vehicle is a ha zardous area!
¢ &. .
_&. WARNING
To help avoid injury, before you check any
thing under the engine compartment lid:
- Switch off the engine.
- Remove the ignition key.

178 Checking and filling
Brake fluid
Hove the brake fluid changed by an experi
enced technician .
Brake fluid absorbs moisture from the air. 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 w ill also decrease considerably and
decrease b rak ing performance .
Therefore, the brake f lu id must be changed
every two years . Always use new brake fluid
which conforms to Federal Motor Vehicle
Standard "FMVSS 1 16 DOT 4".
Brake fl uid is rep laced according to the Audi
maintenance service schedule. Your author
ized Audi dealer is equipped with the necessa
ry special tools and replacement parts, has
the necessary expe rtise, and can d ispose of
the used fluid .
.&_ WARNING
- Brake fluid is po iso nous. It mus t be s to r
ed on ly in the closed orig inal con taine r
o ut o f th e reac h of children!
- Br ake f ailure can resul t from old o r in ap
propr iate brake fluid. Observe these pre
caut ions:
- Use o nly brake fluid that meets SAE
specification
J 1703 and co nfo rms to
Federal Motor Vehicle Sta ndard 116 .
A lways check wi th you r a uthori zed Aud i
dealer to m ake sur e you are u sing the
correct br ake f luid. The co rrec t type of
b rake fluid is a lso indica ted on the
b rake fluid reservoir .
- The brake flui d must be new. Heavy use
of the brakes can ca use a vapor loc k if
the brake fl uid is left in t he system too
l o ng. This can ser io usly affect the effi
ciency of the brakes as well as yo ur
safety. This could result in an acc ident.
Brake fluid will damage the paint of your
veh icle.
{® For the sake of the environment
Because of the p rob lem of proper disposal
of brake fluid as well as the spec ia l too ls
required and the necessary expertise, we
recommend that you have the brake flu id
cha nged by yo ur autho rized Aud i dea le r.
Battery
General information
All work on the ba ttery requires technical
knowledge.
The battery is located be hind the cov er in the
l u ggage compa rtment. Remove the cover by
pu shing i t to the left an d lift ing it o ut.
The battery is practically maintenance-free
and is checked as pa rt of your ve hicle's main
tenance se rv ices .
You are we ll advised to replace a battery that
i s older tha n 5 yea rs .
Disconnecting the battery terminals
Some vehicle f unctions (power window reg u
l ators, for example) are lost if the battery te r
mina ls are disconnected. T hese functions have
to be relearned after the battery termina ls are
co nn ected aga in . T o p revent th is, t he battery
shou ld only be disconnected from the ve hicle
elect ric al sy stem w hen abso lutely ne cessary
f or rep airs.
Vehicles not driven for long periods
The battery becomes d ischarged due to quies
cent current consume rs even when the vehicle
is not used. With extended pe riods of non-use
in t he
cold season, yo u should have t he ve hi
cle b attery removed by an autho riz ed Aud i
dealer or qualif ied workshop and stored in an
frost-free place. T his prevents the battery
from "freezing" and thereby being destroyed.
D uring the
warme r seasons it is enough to
disco nnect the battery negat ive terminal. Oc-
cas ionally charge a disconnected battery.

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 183
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.

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.

A 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 loss of
control.
- Always keep chemicals that can cause tire damage, such as grease, oil, gasoline
and brake fluid away from t ires.
- Tires age even if they are not be ing used
and can fail suddenly, especially at high
speeds . Tir es 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.
