Check ing and F illing
The brake fluid rese rvoir is located at the rear
partition of the engine compartment on the l eft
side ¢
page 205 .
The fl uid level may drop slightly after some time
due to the automatic adjustment of the brake
pads . This is not cause for alarm.
If th e b rake fl uid level fa lls considerably be low
the "M IN" mark, the b rake warning/ind icator
lig ht ( U.S. mode ls :
1111 , Canadian models:. )
will come on ¢
page 15. Do not contin ue to oper ­
ate the vehicle . T he comp lete brake system
should be thoroughly checked by an authori zed
Aud i dealer or qualified workshop and the cause
corrected . If the brake flu id level is too low, the
b rake warning/indicator light will i llum inate.
Contact a n author ized Audi dealer
immediately .
{D) Tips
The brake fluid reservoir is located under­
neath the cover .
Changing brake fluid
Have the brake fluid changed by an experienced
technician .
Brake fluid absorbs mo isture from the air. If the
water content in the b rake fluid is too high, cor­
rosion in the brake system may resu lt afte r ape ­
riod of t ime. The boiling poi nt of the brake flu id
will also decrease cons iderably and decrease
b raking perfo rman ce.
Therefore, the brake fluid must be changed
every
two year s.
Always use new brake fluid wh ic h con­
forms to Fede ral Motor Veh icle Standard "FMVSS
1 16 DO T 4".
The brake fluid reservoir can be diff icult to reach,
therefore, we recommend that yo u have the
brake fl uid changed by yo ur autho rized
Audi
dealer .
Your dealer has t he corre ct tools, t he
right brake fluid and the know-how to do this for
you.
A WARNING
- Brake fluid is poisonous. It must be stored
only in the closed orig inal container out of
the reach of chi ldren!
212
- Bra ke fa ilure ca n result from old or inapp ro­
priate brake fluid . Observe these precau­
tions:
- Use only brake fluid t hat meets SA E speci­
fi ca ti on
J 170 3 and con forms to Federa l
Motor Ve hicle Standard 116 . Always check
wi th yo ur autho rized Audi dea le r to make
s ur e yo u are using the correct brake fluid .
The correct type of brake flu id is also ind i­
cated on the b rake fluid reservo ir .
- The brake fluid m ust be new . Heavy use of
the brakes can cause a vapo r lock if the
brake fluid is left in the system too long .
This can se riously affect the efficiency of
the b rakes as well as your safety . This
could resu lt in an accident .
(D Note
Brake fluid will damage the paint of your veh i­
cle.
@ For the sake of the environment
Because of the problem o f proper d isposa l o f
brake fluid as well as the spec ial too ls re­
q ui red a nd the necessary expertise, we rec­
omme nd that you have the bra ke f luid
changed by yo ur autho rized Aud i dea le r.
Battery
, General information
U nder normal operating condit ions, the battery
i n your Audi does not need any maintenance.
With
high outside temperatures or long daily
drives we recommend that you have the elect ro ­
lyte level c hecked by an au thorized Aud i dealer o r
qualified workshop. The electro lyte level shou ld
a lso be che cked each time the battery is c ha rged
~ page 214.
Have the batte ry chec ked when you take yo ur ve­
hicle in for service. You are we ll adv ised to re­
pla ce a battery tha t is older than 5 yea rs.
With certain types of airbag deployment, t he
batte ry is d iscon nected from the ve hicle electri­
ca l system for safety reasons ¢.&.

Wheels
Wheels and Tires
General information
.,.Check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob­
jects from the tire tread.
.,. If driving over curbs or similar
obstacles, drive slowly and ap­
proach the curb at an angle.
.,.Have faulty tires or rims re­
placed immediately.
"'Protect your tires from oil,
grease and fuel.
.,.M ark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled.
"'Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as
possible.
(D Note
-Please note that summer and
winter tires are designed for
the conditions that are typical in those seasons. Audi recom­
mends using winter tires dur­
ing the winter months. Low
temperatures significantly de­ crease the elasticity of summ­
er tires, which affects traction
Wheels
and braking ability. If summer
tires are used in very cold
temperatures, cracks can form
on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or
chromed rims must not be
used in winter driving condi­
tions. The surface of the rims
does not have sufficient corro­
sion protection for this and
could be permanently dam­ aged by road salt or similar
substances.

Operating your vehicle
outside the U.S.A. or
