off
the brake pads or remove any ice coatings.
When you are driving at h igher speeds wit h
the windshield wipers on, the brake pads will briefly touch the brake discs in regular inter­
va ls so as to improve reaction t ime when brak­
ing on wet surfaces. You the driver w ill not no­
tice anything.
The effectiveness of the brakes can be reduced
when the vehicle is dr iven on a salt -covered
road and the brakes are not used . Here too,
you should clean

Cor ro sion
There may be a tendency for dirt to bui ld up
on the brake pads and corrosion to form on
the discs if the car is not dr iven regularly or
only for short trips with little use of the brakes .
If the brakes are not used frequently, or if cor­ rosion has formed on the discs, it is advisable
to clean
off the pads and discs by braking

A WARNING
- You should perform braking maneuvers
for the purpose of cleaning the brake
system only if road conditions permit.
Other road users must not be put at risk -
you may cause an accident!
- Before descend ing a steep grade, reduce
speed and sh ift transmission into a lower
gear or lower dr iving range . Do not ride
the brakes or hold the pedal down too
long o r too often . Th is could cause the
brakes to get hot and diminish braking
efficiency .
- Do not "ride the brakes" by rest ing you r
foot on the pedal when you do not intend
to brake . This may cause the brakes to
overheat, p remature wear and increased
stopping distance.
- Under certain cl imatic and operating
conditions such as passing thro ugh wa ­
ter, dr iv ing in heavy rain or after washing
the vehicle, the effectiveness of the brakes can be reduced . In winter, ice can
accumu late on the brake pads, lin ings,
discs and drums . Carefully app ly brakes
for a test. Brakes will dry and ice coat­
ings w il l be cleaned
off after a few care­
fu l brake applicat ions.
- Driving for an extended period o f time on
salt- covered roads wi thout using your
brakes can a lso affect braking efficiency .
Clean
off accum ulated salt coating from
brake discs and pads with a few careful
brake applications.
- If you damage the front spoiler, or if you
install a different spoiler, be sure the air
f low to the front brakes is not obstruct­
ed. Otherw ise the brake system could
overheat reducing the effectiveness of
the entire brake system.
- Failure of one brake circuit will impair
the braking capab ility result ing in an in­
creased stopping distance . Avoid driving
the vehicle and have it towed to the near-
est A udi dealer or qualified wo rkshop.

208 Cleaning and protection
Cleaning and protect ion
General information
Regular core preserves vehicle value .
Any automobile is exposed to industrial
fumes, corrosive road salt, etc. A well cared
for Audi can look like new many years after
purchase . Regular and correct care w ill con­
tr ibute to maintaining the beauty and value of
your Aud i.
Furthermore, good care may be a condition
for substantiating a warranty claim should
corrosion damage or paint defects occur.
Your author ized Audi dealer has a variety of
dedicated vehicle-care products and can ad­
vise which ones to use for cleaning the exter i­
or and interior of your vehicle .
Whether you use products recommended by
Audi or other commercially available clean ing
agents, please make sure you apply them cor­
rectly .
A WARNING
-Cleaning agents may be poisonous. Keep
them out of the reach of children.
- Heed all caut ion labels.
- Always read directions on the container
before using any product . Follow the di­
rect ions carefu lly.
- Most chemical cleaners are concentrated
and have to be diluted.
- Use spot removing fluids only in well
ventilated areas.
- Do not use gasoline, kerosene, d iesel
fuel, nail pol ish remover or other volatile
fluids. They may be toxic, flammable or
hazardous in other ways. Do not wash,
wax or dry the vehicle with the ignit ion
on or the engine running.
- Do not clean the undersides of chassis,
fenders, wheel covers, etc. without pro­
tecting your hands and arms. You may cut yourself on sharp-edged metal parts. -
Moisture and ice on brakes may impair
brak ing eff ic iency
c::> page 194 , General
information.
Test the brakes carefully
each time you wash the vehicle .
@ For the sake of the environment
Select only environ mentally friendly clean­
ing products. Leftover cleaning products
should not disposed of in the household
waste .
Care of exterior
Washing
Frequent washing protects the vehicle .
The best p rotection against environmental in ­
fluences is
frequent washing and waxing . How
often this is required depends on:
- How much the veh icle is used
- Where the vehicle is parked (garage, in the
open under trees, etc.)
- The seasona l and weather conditions
- Environmental influences
T he longer b ird droppings, insects, tree resin,
road and industria l gr ime, tar, soot, road salt
and other materials remain on the vehicle body, the more lasting their destructive ef­
fects will be . High temperatures caused by ex­
posure to intense sunlight intensify the corro­
sive effect, particularly when humidity is high as well.
Under certain circumstances,
weekly washing
may be necessary. Under other conditions, a
monthly washing and waxing may be ade­
quate .
After the winter, the underside of the vehicle
should be thoroughly washed, preferably in a
professional car wash.

Engine oil
Engine oil specifications
The engine oil used in your Audi needs the
right kind of oil.
The engine in your Audi is a sophisticated
powerplant that was built to exacting specifi­
cations. This eng ine needs the right kind of
engine oil that meets specifications regardi ng
quality and viscosity so that it can run smoothly and reliably. Choosing the right oil
and changing oil within the time and mileage
intervals p rinted in you r vehicle's Warranty
&
Maintenance booklet matters a lot more to­
day than it did years ago . Audi has developed
a special quality standard for engine oil that
will hel p assure that your vehicle's engine will
get the lubrication it needs for proper opera­
tion.

234 Checking and filling
scalding from hot coolant by following
these steps .
- Turn off the eng ine and a llow it to cool
down.
- Protect your face, hands and arms from escaping flu id and steam by cover ing
the cap with a large, thick rag .
- Turn the cap slowly and very carefully
i n a counter-clockwise direction while
apply ing l ight, downwa rd p ress ure on
the top of the cap .
- To avo id being burned, do not sp ill an­
tifreeze or coolant on the exhaust sys­
tem or hot engine parts . Under certain
conditions, the ethylene glyco l in en­
gine coolant can catch f ire .
- Antifreeze is poisonous . Always store an­
tifreeze in its or iginal container and we ll
out of the reach of children .
- If you drain the coolant, it must be
caught and safely stored in a proper con­
tainer clear ly marked "poison".
@ Note
- Coolant po llutes the env ironment and
could cause an engine fire . Excess coo l­
ant will be forced out through the pres­
sure re lief valve in the cap when the en­
gine becomes hot.
- If, in an emergency, on ly water can be
added, the correct ratio between water
and antifreeze
c::> page 232 must be re­
stored as soon as possible .
@ For the sake of the environment
Drained coolant should not be re used. Al­
ways dispose of used coolant while observ­
ing all environmental regulat ions .
Radiator fan
The radiator fan switches on automatically by
itself
An auxiliary e lectr ic radiator fan switches on
and off depending on coolant temperature
and other vehicle operating cond itions. After you switch the engine off, the aux
iliary
fan can cont inue running for up to 10 minutes
- even w it h the ignition off. It can even switc h
on again later by itself
c::> .&. , if
- the temperatu re of the engine coo lant rises
due to the heat build-up from the engine in
the engine compartment, or
- the engine compartment heats up because
the vehicle is parked in intense sunlight.
A WARNING
-- To reduce the risk of persona l injury nev-
er touch the radiator fan.
- The a uxiliary electric fan is temperat ure
contro lled and can sw itch on suddenly
