-To avoid being burned, do not spi ll anti­
freeze or coolant on the exhaust system or hot engine parts. Under certain condi­
tions, the ethylene glycol in engine cool­ ant can catch fire.
- Antifreeze is poisonous. Always store anti­
freeze in its original conta iner and well out
of the reach of ch ildren .
-If you drain the coolant, it must be caught
and safely stored in a proper container
clearly marked "poison" .
(D Note
-Do not add coolant if the expansion tank is
empty . Air could enter the cooling system
and damage the eng ine .
If this is the case,
do not continue driving. Seek profess ional
ass istance.
- Coolant pollutes the env ironment and could
cause an eng ine fire . Excess coolant will be
fo rced out through the pressure relief valve
i n the cap when the eng ine becomes hot.
- If, i n an emergency , only water can be add­
ed, the correct ratio between wa ter and an­
tifreeze
~ page 200 must be restored as
soon as possib le .
@) For the sake of the environment
Drained coolant should not be reused. Always
dispose o f used coolant while observ ing all
environmental regulations .
Radiator fan
The radiator fan switches on automatically by it­
self.
The radiator fan is driven by the engine via the V­
be lt . The viscous clu tch regulates the speed of
the fan ac cording to the temperature of the cool ­
ant.
An auxiliary e lectr ic rad iator fan* switches on and
off depend ing on coolant temperat ure and othe r
veh icle operati ng conditions.
Afte r you switch the engine off, the auxiliary fan
can continue runn ing for up to 10 minutes -even
Ch eck in g and Fillin g
with the ignition off . It can even switch on again
later by itself¢& , if
- the temperatu re of the engine coo lant rises due
to the heat build- up from the engine in the en­
gine compartment, or
- the engine compartment heats up because the
veh icle is parked in intense sun light .
A WARNING
-To reduce the risk of persona l injury never
touch the radiator fan .
- The auxiliary electric fan is temperature con­ trolled and can switch on suddenly even
when the engine is not running.
- The a uxiliary radiator fan sw itches on auto­
matica lly when the engine coolant reaches a
certain temperature and will continue to run
until the coolant temperature drops.
Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a quick
glance .

r e servoir
Before you check anyth ing in the engine compart ­
ment,
al way s read and h eed all WARNIN GS
¢ _.& in Working in the engine compartment on
page 195 .
.,. Read the brake fluid level from the b rake fluid
reservoir ¢
fig. 176, ¢ page 197, fig . 172 . The
brake fluid level must be between the
"MIN "
and "MAX " markings.
20 3

Checking and F ill in g
The brake fluid reservoir is located at the rear
partition of the engine compartment on t he left
side ¢
page 197.
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 the b ra ke fluid level fal ls considerably below
the "MIN" mark, the brake warn ing/indi cator
light (U.S. models:
1111 , Canadian models: . )
will come on ¢
page 15. Do not contin ue to oper­
ate the vehicle . The complete brake system
should be thoroughly checked by an author iz ed
Aud i dealer or qualified workshop and the cause
corrected . If the brake fluid level is too low, the
brake warning/ind icator light w ill illuminate .
Contact an authorized Audi dealer
i mmed iately .
{D) Tips
The brake fluid reservoir is located under­
neath the cove r.
Changing brake fluid
Have the brake fluid changed by an experienced
technician .
Brake fluid absorbs moist ure from the a ir. If the
water content in the brake fluid is too high, cor­ rosion in the brake system may result after a peri­
od of time . The boiling point of the brake flu id
w ill also decrease conside rably and dec rease
b rak ing perfo rmance.
Therefore, the brake flu id must be changed
e ve ry
two year s.
Always use new brake fluid w hich con­
forms to Fede ral Motor Vehicle Standard "FMVSS
1 16 DOT 4".
The brake fluid rese rvoir can be difficult to reach,
therefo re , we recommend that you have the
b rake fluid changed by your author ized
Audi
dealer .
Your dealer has the correct too ls , the
right brake fluid and the know-how to do t his for
you.
A WARNING
- B rake fluid is poisonous. It must be stored
on ly in the closed original container out of
the reach of children!
204
- Brake fail ure can resu lt from o ld or inappro­
priate brake fluid. Observe these precau ­
tions:
- Use only b rake fluid that meets SAE spec i­
f ica tion
J 170 3 and conform s to Federa l
Motor Vehicle Standard 116. Always check
with yo ur autho rized Audi dea le r to make
su re you are using the correct brake fl uid.
The correct type of brake flu id is also ind i­
cated on the brake fluid reservoir.
- The brake fl uid must be new. Heavy use of
the brakes can cause a vapor lock if the
brake f luid is left in the system too long.
This can seriously affect the efficiency of
the brakes as well as your safety. This
could result in an acc ident.
(D Note
Brake fluid will damage the paint of your vehi­
cle.
@ For the sake of the env ironment
Because of the prob lem of prope r disposal of
brake fluid as well as the special tools re­
qu ired and the necessary expert ise, we rec­
omme nd that you have the brake flu id
changed by you r autho rized Aud i dea le r.
Battery
, General information
U nder normal operating conditions, the battery
i n your Audi does not need any maintenance.
Wi th
high outside temperatures or long daily
drives we recommend that you have the e lectro ­
lyte level checked by an a uth orized Aud i deale r o r
qualified workshop . The electrolyte leve l should
a lso be checked each time the batte ry is c ha rged
~ page 206.
Have the battery checked when yo u take your ve­
hicle in for service . You a re well adv ised to re­
pla ce a battery that is older tha n 5 years.
With certain types of airbag deployment, the bat ­
te ry is disconnected from the veh icle elect rical
system for safety reasons

and disposal of the airbags on page 1 45.

Wheels
A WARNING
Wheel bolts that are tightened or repaired in­correctly can become loose and result in loss
of vehicle control , which increases the risk of
an accident. For the correct tightening specifi­
cation, refer to
c:> page 231, After changing a
wheel.
- Always keep the wheel bolts and the threads
in the wheel hub clean and free of grease.
- Only use wheel bolts that fit the rim .
- Always have damaged rims repaired by an
authorized Audi dealer or authorized repair
facility. Never repair or disassemble rims
yourself, because this increases the risk of an accident.
Winter tires
Winter tires significantly improve the vehicle's handling when driving in winter conditions . Be­
cause of their construction (width, compound,
tread pattern), summer tires provide less traction
on ice and snow.
.., Use winter tires on all four wheels .
.., Only use winter tires that are approved for your
vehicle.
.., Please note that the maximum permitted
speed may be lower with winter tires
c:> .&,.
Your authorized Audi dealer or authorized re­
pai r facility can inform you about the maximum
permitted speed for your tires .
.., Check the tire pressure after installing wheels
c:> page 219.
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0 .1S7 inch (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages, re ­
gardless of the remaining tread.
A WARNING
-Never drive faster than the maximum per­
mitted speed for your t ires. This could cause
the tires to heat up too much . This increases
the risk of an accident because it can cause
the tire to burst.
224
- Always adapt your driving to the road and
traffic conditions. Drive carefully and reduce
your speed on icy or slippery roads. Even
winter tires can lose traction on black ice.
@ For the sake of the environment
Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fuel
consumpt ion.
(D Tips
You can also use all season tires instead of
winter tires. Please note that in some coun­
tries where winter tires are required, only win­
ter tires w ith the
& symbol may be permit­
ted.
· Snow chains
Snow chains improve traction in the snow .
.., Only install snow chains on the front wheels.
This applies also to vehicles with all wheel drive* .
.., Check and correct the seating of the snow
chains if necessary after driving a few feet. Fol­
low the instructions from the manufacturer .
.., Note the maximum permitted speed when driv­
ing with snow chains . Do not exceed 30 mph
(SO km/h) .
Snow chains not only improve the
driving in win­
ter road conditions, but also the
braking.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authorized Audi dealer or author­
ized repair facility to see if you may use snow
chains .
Use
fine-mesh snow chains. They must not add
more than 0.53 inch (13.S mm) in height, includ­
ing the chain lock.
You must remove the chains when driving on
roads that are
free of snow. When roads are free
of snow, snow chains can impair handling and .,.

A WARNING
Using inco rrect snow cha ins or installing snow
chains incorrectly can resu lt i n loss of vehicle
cont ro l, whic h increases the r isk of an acci ­
de nt.
(D Note
Snow chains can dama ge the r ims/whee l cov­
ers * if th e cha ins come into d irect contact
w it h them. Remove the whee l cov ers* f irst .
Use coat ed snow c hains.
Low aspect ratio tires
Your Au di is factory -equip ped wi th low as pect ra ­
tio ti res. T hese ti res have bee n thoroughly teste d
a nd been se le cted specific ally fo r your model fo r
t he ir su perb pe rformance, road feel and handling
u nd er a variety o f driving conditions . Ask yo ur au­
thor ized A udi dealer for mo re deta ils.
The low aspe ct r atio of these ti res i s indic ated by
a numer al of
55 or les s in th e tire's si ze des igna ­
tion. The nu mera l represen ts the ra ti o of the
tire's sidewall he ight in relation to its trea d width
e x pressed in percentage. Convent io na l tires have
a he ight/w idth ratio of 60 or mo re.
The performance of low-aspect-ratio tires is par­
ticularly sensitive to improper inflation pres­
sure . It is therefore important that low aspect
ratio tires are inflated to the specified pressure
and that the inflation pressure is regularly
checked and maintained . Tire pressures should
be checked at least once a month and always
before a long trip
¢ pag e 219.
What you can do to avoid tire and rim
damage
L ow aspec t rat io t ires ca n be damaged more easi­
l y by impact wi th pot ho les, curbs, gulli es or
r idges on the road, par ticularly if the tire is un­
de rin fla ted.
In o rder to m inim ize the occu rrence o f impact
damage to the t ires of your v ehicl e, we recom-
Wheels
me nd that yo u observe the follow ing p recau ­
t ions:
- Alw ays m aintain r eco m me nded infl ation pre s­
sures. C heck your tire pressure every 2,000
m iles (3,00 0 km) an d ad d air if necessary .
- Dr ive c arefully on road s wi th pot holes, deep
gu llies o r ridges. The impac t from dr iv ing
through or over s uch obstacles can damage
your tires . Impact with a curb may a lso ca use
damage to your tires .
- After a ny impact, imme diate ly inspect yo ur
tires o r have them inspected by the nearest au­
thorized A udi dealer. Rep lace a damaged t ire as
soon as possible.
- Inspect your tires every 2,000 m iles (3,000 km)
for damage and wear . Damage is not always
easy to see. Damage can lead to loss of air and
unde rinflation, w hich could even tually cause
t ire failure .
If you beli eve that a t ire may have
been damaged, re place the t ire as soon as pos­
s ible.
- These ti res may wear more quickly tha n oth ers .
- Please also remember that, wh ile these tires
delive r responsiv e han dling, they may r ide less
comfortably and make mo re no ise than other
c h o ic e s.
