Checking brake fluid level
Fig . 133 Engine compa rtment: cove r on the brake fluid
reservo ir
Before you check anything in the engine com­
partment,
a lw ays read and h eed all WA RN­
ING S ¢&. in Working in the engine compart ­
ment on page 164.
,.. Read the brake fluid level from the brake
fluid reservoir¢
page 166, fig . 128. T he
brake flu id leve l must be between the "MIN"
and "MAX" markings.
The brake flu id rese rvo ir is located behind the
rear part ition of the eng ine compartment o n
the left side ¢
page 166.
The fluid level may drop slightly after some
time due to the automatic adjustment of the b rake pads . This is not cause for alarm.
If the brake fluid level falls
considerably be­
low the "MIN" mark, the brake warning/indi­
cator light (U.S. models: . , Canadian mod­
e ls: . ) w ill come on
¢page 14. Do not con­
tinue to operate the vehicle. The comp lete
brake system shou ld be thoroughly checked
by an authorized A udi dealer or other quali­
fied facility and the cause corrected.
If the
brake fluid level is too low, the brake warn ing/
indicator light w ill illuminate. Contact an au­
thor ized Audi dealer
imm ediatel y.
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 flu id will also decrease conside rably and
decrease braking pe rformance.
Therefore, the brake fluid must be changed
eve ry two y ears. Always use new brake flu id
which conforms to Federal Motor Veh icle
Standard "F MVSS 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 fl uid 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 flu id. Observe these pre­
cautions:
- Use only brake f luid that meets SA E
specifica tion
J 1 7 03 and conforms to
Federa l Moto r Ve hicl e Standard 1 16.
Always check with yo ur authorized Aud i
dealer to make sure yo u are using the
correct brake fluid. The correct type of brake f lu id is also ind icated on the
brake flu id 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
l ong. This can seriously affect the effi­
c iency of the brakes as well as your
safety. This cou ld resu lt in an accident.
(D Note
Brake fluid will damage the paint of your
vehicle .

snow c hains are suitably cove red . Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow cha in manufacturer when doing so.
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 must always be tightened to the
correct torque.
The design of whee l bolts is matched to the
factory insta lled r ims . If different rims are fit­
ted, the correct wheel bo lts with the right
length and correctly shaped bolt heads must
be used. This ensures t hat wheels are fitted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bo lts from a different vehicle -even if it
i s the same model
¢ page 227.
A WARNING
Imprope rly tig htened or maintained wh eel
bolts can become loose ca using loss of
con trol, a collision and serious person al in­
jury.
- Always keep the w heel bolts and the
threads in the wheel hubs clea n so the
wheel bolts can tu rn easily and be p rop ­
er ly tightened .
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can become loose w hile driving if greased or
o iled, even if tig htened to the specif ied
torque.
- Only use whee l bolts that belong to the
rim being installed.
- Never use different whee ls bolts on your
vehicle.
- Always maintai n the co rrect tig htening
torq ue fo r the wheel bo lts to reduce the
risk of a wheel loss. If the tightening tor-
Tire s an d wheel s 197
que of t he whee l bolts is too low, they
can loosen and come out when the vehi­
cle is mov ing. If the tig htening torq ue is
too high, the wheel bolts and threads
can be damaged and the whee l can be­
come loose.
(D Note
The specified torque for the whee l bolts is
90 ft lb (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm). Torq ue whee l bolts diago­
nally. After changing a whee l, the tor que
must be checked as soon as possible with a
torq ue w rench -prefe rably by an au thor­
iz ed A udi de aler or qu alified workshop .
Low aspect ratio tires
Your Audi is factory -eq uipped w ith low aspect
r atio tires . These tires have been tho roughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and handli ng under a var iety of driving condi­
tions . Ask your authorized Audi dealer for
more d etails.
The low aspect ratio of these t ires is ind icated
by a numeral of
55 or less in the tire's s ize
designation . The numeral represents the ratio
of the t ire's sidewa ll height in relation to its
t read width exp ressed in pe rce ntage. Conven­
t iona l tires have a he ight/w idth rat io of 60 or
more.
The performanc e of low-a spect-ratio tire s is
particularly sensitive to impr oper inflation
pre ssure .
It is therefore important that low
a spect ratio tire s are inflated to the specified
pres sure and that the inflation pressure is
regularly checked and maintained. Tire pre s­
sures should be checked at least once a month and always befo re a long trip
¢ page 186, Checking tire pressure.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w it h potholes, curbs, gul lies ..,.
