blink until you add coo lant and the level has been
restored to normal. Even though there is an e lec­
tr ic coo lant level sensor, we still recommend you
check the coo lant level from t ime to time.
Coolant los s
Coolant loss may indicate a leak in t he cooling
system. In the event of coolant loss, the cooling
system should be inspected immediately by your
authorized Audi dealer. It is not enough merely
to add coolant.
I n a
s e a led 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 engine and allow it to coo l
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-clockw ise d irection while applying
light, downward pressure on the top of the
cap.
- To avoid being burned, do not spill ant i­
freeze or coolant on the exhaust system or hot eng ine parts . Under ce rtain conditions,
the ethy lene g lycol in engine coolant can
catch fire.
{il) Note
Do not add any type of rad iator leak sealant
to your veh icle's engine coolant . Adding radia­
to r repair f lu id may adverse ly affect the func­
tion and performance of your cooling system
and could resu lt in damage not covered by
your New Vehicle Limited Warranty.

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
c!,> page 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 the b ra ke fluid level fal ls considerably below
the "MIN" mark, the brake warn ing/indicator
light (U.S. models:
1111 , Canadian models: . )
will come on
c!,> 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!
200
- 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
c:!,> page 202.
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
c:!,> & in Repair, care
and disposal of the airbags on page 1 42.

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 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 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 215.
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.
220
- 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 .,.
