Brake fluid
Checking brake fluid level
Fig. 192 Engine compartment : cove r on the brake fl uid
reservo ir
Before you check anything in the engine com
partment,
always read and heed all WARN
INGS ~ .&. in Working in the engine compart
ment on page 224.
.,. Read the brake fluid level from the brake
fluid reservoir~
fig. 192 , ~ page 226,
fig.
188. The brake fluid leve l must be be
tween the "MIN" and "MAX" markings .
The location of the brake flu id reservoir can be
seen in the engine compartment illustrat ion
~ page 226.
The fluid level may drop slightly after some
time due to the automatic adjustment of the
brake pads . Th is is not cause for alarm.
I f the brake fluid level falls
considerably be
lo w the "MIN" mark, the brake wa rning/indi
cator light
1111 (U.S. models)/ . (Canadian
models) will come on~
page 15. Do not con
tinue to operate the vehicle. The comp lete
brake system should be thoroughly checked
by an authorized Audi dealer or other quali
fied facility and the ca use corrected. If the
brake fluid level is too low, the brake warning/
indicator light w ill illuminate . Contact an au
thorized Audi dealer
immediately .
Changing brake fluid
Have 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
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 pe rformance .
Therefore, the brake fluid must be changed
every two years. Always use new brake flu id
which conforms to Federal Motor Vehicle
Standard "FM VSS 116 DOT 4".
The brake fluid reservoir can be diff icult to
reach, therefore, we recommend that you
have the brake fluid changed by your author
ized
Audi dealer . Your dealer has the correct
tools, 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 in the closed original container
out of the reach of children!
- Brake failure can resu lt from o ld or inap
propriate brake fluid. Observe these pre
cautions:
- Use only brake fluid that meets SA E
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 flui d is also ind icated 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 effi
c ie ncy of the brakes as well as your
safety. This could result in an accident.
(D Note
Brake fluid will damage the paint of your
vehicle .
unbalanced, resulting in vib rations you can
usually feel through the steering wheel.
Unba lanced wheels mus t be rebalanced to
avoid excessive wea r on s teer ing, suspens ion
and tires. A wheel must a lso be rebalanced
when a new tire is installed.
Incorrect wheel alignment
Inco rrect whee l alignment can cause exces
sive tire wea r, impair ing t he safety of the veh i
cle. If t ires show excess ive wear, have the
wheel alignment checked by an authorized
Audi dealer or qualified workshop.
All-wheel d rive
Ve hicles w it h quattro must always have tires
of the s ame s ize, construction and tread type.
F or detai ls see
¢ page 198 .
A WARNING
Sudden tire failure can lead to loss of con
trol, a crash and serious persona l injury!
- Never drive a veh icle when the tread on
any t ire 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"hydrop lan ing" and loss of
co ntrol.
- 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
sp eeds.
- Never mount used tires on yo ur vehicle if
yo u are not sure of their "previous histo
ry." Old used ti res may have been dam
aged even though the damage cannot be
seen that can lead to s udden tire failure
and loss o f vehicle control.

tremely low. If you do drive with snow
chains on while the vehicle is at this lev
el, the snow chains might severe ly dam
age the wheelhouse and other parts of
the veh icle .
@ Tips
Where snow cha ins are mandatory oncer
tain roads, this normally also applies to
veh icles with all -wheel dr ive.
Wheel bolts
Wheel bolts mu st always be tigh tened to the
correc t torque .
The design of whee l bolts is matched to the
factory in sta lled r ims. If different rims are fit
ted, the correct wheel bolts with the right
length and correctly shaped bolt heads must
be used . This ensures that wheels are f itted
secure ly and that the brake system f unctions
correctly .
In certain circumstances, you may not use
wheel bolts from a d iffe rent vehicle -even if it
i s the same mode l
¢page 285.
A WARNING
Imprope rly tig hte ned or maintained whee l
bolts can be come loose causin g loss of
contro l, a co llision and serious persona l in
jury .
- Alw ays keep the w heel bolts and the
th reads in the wheel hubs clea n so the
wheel bolts can turn easily and be prop
er ly tightened .
- Never grease or oil the wheel bo lts and
the threads in the w heel h ubs. They can
become loose while driving if greased or
o iled, even if tightened to the specif ied
torque.
- Only use wheel bolts that belong to the rim being installed.
- Never use different whee ls bolts on your
vehicle .
- Always maintain the co rrect tightening
torq ue for the wheel bo lts to reduce the
Tire s an d wheel s 257
risk of a wheel loss. If the tighte ning tor
que of t he wheel bolts is too low, they
can loosen and come out when the vehi
cle is mov ing . If the tighte ning torque is
too h igh, the wheel bol ts and threads
can be damaged and the whee l can be
come loose.
(I) Note
The specified torque for the whee l bolts is
90 ft lb ( 120 Nm) with a tole ranc e of± 7,4
ft lb(± 10 Nm). Torq ue whee l bolts diago
nally. Afte r cha nging a whee l, the torq ue
must be checked as soon as possible wi th a
torque w rench -prefe rably by an au thor
i z ed Audi dealer or qualif ied workshop .
Low aspect ratio tires
Your Audi is facto ry-eq uipped with low aspect
ratio tires. These tires have been thoro ughly
tested and been se lected specifically for your
model for their superb performance , road fee l
and handling under a variety of driving cond i
tions . Ask your authorized Audi dealer for
more details.
The low aspect ratio of these t ires is ind icated
by a numeral of
55 or less in the tire's size
designation . The numera l rep resents the ratio
of the t ire's sidewall height in relation to its
t read width ex pressed in perce ntage. Conven
tion al tires have a he igh t/w idth ratio of 60 or
more.
The performance of low-aspe ct-ratio tire s is
particularly sensitiv e to improper infla tion
pres sure. It is therefore important that l ow
a spect ratio tires are inflated to the specified
pre ssure and that the inflation pressure is
regularly checked and maintained. Tire pres·
sures should be checked at least once a
month and always before a long trip

What you can do to avoid tire and rim
damage

easily by impact w it h potholes , curbs, gul lies ..,.

([) Note
-Be awa re of the fo llowing points befo re
li fting t he vehicle:
- The vehicle should never be lifted or
jacked up from underneath the engine oil pan, the transmission housing, the
front or rear axle or the body side
members. This could lead to serious
damage.
- To avoid damage to the underbody or
chassis frame , a rubber pad must be
i nserted between the floor jack and
the lift points.
- Before driving over a workshop hoist,
check that the veh icle weight does not
exceed the permissible lifting capacity
of the hoist.
- Before driving over a workshop hoist,
ensure that there is sufficient clear
ance between the hoist and low parts
of the vehicle.
