Check ing and F illing
blink until you add coolant and the level has been
restored to normal. Even though there is an e lec ­
tr ic coolant level sensor, we still recommend you
check the coo lant level from time to time.
Coolant los s
Coolant loss may indicate a l e ak in the cooling
system. In the event of coolant loss, the cooling
syst em should be insp ected immediately by your
authorized Audi dealer. It is not enough merely
to add coolant.
I n a
s e aled system, losses can occur only if the
boiling point of the coo lant is exceeded as a re­
sult of overheating.
A WARNING
The cooling system is under pressure and can get very hot. Reduce the risk of scalding from
hot coolant by following these steps.
- Turn off the eng ine and allow it to cool
down .
- Protect your face, hands and arms from es­
caping fluid and steam by covering the cap
with a large, thick rag.
- Turn the cap slowly and very carefully in a
counter-clockwise direction wh ile apply ing
l ight, downward pressure on the top of the
cap .
- To avo id being burned, do not sp ill anti ­
freeze or coolant on the exhaust system or
hot eng ine parts . Under certain conditions,
the ethy lene g lycol i n engine coolant can
catch fire.
{Q) Note
Do not add any type of radiator leak seala nt
to your veh icle's engine coolant . Adding radia­
to r repa ir fluid may adversely affec t the func­
tion and performance of yo ur cooling system
and could result in damage not covered by
your New Vehicle Limited Warranty.

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
c!,> pag e 193 .
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
c!,> 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!
200
- 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
c:!,> page 202.
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

and disposal of the airbags on page 1 42. .,.

Wheels
and a special procedure. You must not repair or
disassemble them¢&. .
A WARNING
Wheel bolts that are tightened or repaired in­
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct t ightening specifi ­
cation, refer to ¢
page 22 7, 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 Aud i
Service Facility . Never repair or disassemble
rims yourself, because this inc reases the risk
of an accident.
Winter tires
Winter tires s ignificantly improve the vehicle's
handling when driving in winter conditions . Be­
cause of their construction (width, compound,
tread pattern), summer tires provide l ess trac­
tion 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
q .&,. . An
authori zed Audi dealer or authori zed Audi Serv­
ice Facility can inform you about the maximum
permitted speed for your tires .
.,. Check the tire pressure after install ing wheels
q page 215.
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0 .157 in (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 tires. This could cause
the tires to heat up too much. This increases
220
-
the risk of an accident because it can cause
the tire to burst.
- 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 prov ide 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
winter tires w ith the ~ symbol may be per­
mitted.
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 dr iv­
ing with snow chains. Do not exceed 30 mph (SO km/h).
Snow cha ins 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 combinat ions due to technical reasons .
Check with an author ized Audi dealer or author­
ized Audi Service Facility to see if you may use
snow chains.
Use
fine-mesh snow chains. They must not add
more than 0.53 inch (13.5 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 ..,.
