& 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 descending a steep grade , reduce speed and shift trans­
mission into a lower gear or lower driving position . Do not ride the
brakes or hold the pedal down too long or too often. This could
cause the brakes to get hot and diminish braking efficiency .
• Do not "ride the brakes " by resting your foot on the pedal when
you do not intend to brake . This may cause the brakes to overheat ,
premature wear and increased stopping distance .
• Under certain climatic and operating conditions such as
passing through water , driving in heavy rain or after washing the

vehicle, the effectiveness of the brakes can be reduced . In winter ,
ice can accumulate on the brake pads , linings , discs and drums .
Cautiously apply brakes for a test. Brakes will dry and ice coatings
will be cleaned off after a few cautious brake applications.
• Driving for an extended period of time on salt-covered roads
without using your brakes can also affect braking efficiency. Clean off accumulated salt coating from brake discs and pads with a few
cautious brake applications.
• If you damage the front spoiler , or if you install a different
spoiler, be sure the air flow to the front brakes is not obstructed.
Otherwise the brake system could overheat reducing the effective­
ness of the entire brake system.
• Failure of one brake circuit will impair the braking capability
resulting in an increased stopping distance. Avoid driving the
vehicle and have it towed to the nearest Audi dealer or qualified
workshop.
• Never let the veh icle roll to a stop with the engine shut off .
• If the brake booster is not working, for example when towing
your vehicle , or because the brake booster has somehow been
damaged , the brake pedal must be pre ssed considerably harder to
make up for the lack of booster assistance . •
Anti- lock brake system CABS)
ABS preve nts th e wheels from lo cking under br aking.
The anti -loc k brake syste m (ABS) makes a major contribution to
i nc reas ing active d rivi ng sa fety . You s ho ul d not e xp e ct that braki ng
distances wi ll be
shortened und er all circumstances with ABS .
B ra kin g dis tance may even become s omewhat lon ger, for exa mple,
on gravel or in new snow on s lippery ground, even if you are driving
c aref ully a nd s lowly .

ABS operation
When a vehicle speed of about 10 mph (20 km/h) is reached, an au to ­
matic test sequence is run. Some noise from the pump may be
audible .
I f the speed of a whee l slows down too much relative to vehic le
speed and it starts to lock, brake pressure to this wheel is reduced.
This adj ustment process can be felt as a
pulsing motion of the brake
pedal ,
accompanied by some no ises. You as the driver are intention­
a lly being given the infor mation tha t the wheels are tending t o lock
(ABS control range). In order for ABS to be ab le to operate optima lly
in this range, you must keep the b rake pedal depressed -do not
"pump the brakes".
Brake assistant
The brake power assist un it increases the pressure that you
genera te wi th the brake pedal. I t wo rks only when the e ngine is
running.
Automatic full braking
T his function al lows fu ll bra king in spite of high brake pedal forces
(e .g. whe n the brakes are seve rely s tressed beca use the veh ic le is
fully loaded) . T he driver not ices this function through a reduction of
pedal force a nd increased pedal t ravel. When the brake peda l is
re leased, fu ll braking assist switches off again automatically .
If there is an ABS failure, the brake assistant and automatic fu ll
brak in g ass ist are not available.
& WARNING
• ABS cannot suspend the la ws of physic s. You should keep this
in mind in parti cular on an icy or wet road . If ABS control of braking
intervenes , you should adjust your speed immediately to road and
traffic condit ions . Do not be tempted by the increased safety
provided to take risks -danger of an accident.
• Please keep in mind that the risk of an accident is increased by
driving too fast , particularly in bends and on icy or wet roads , and
& WARNING (continued )
by driving too close to the vehicle ahead . The increased risk of an
accident cannot be redu ced by the brake a ssistant -danger of an
accident .
[ i ] Tips
If a ma lfunction occurs in the ABS, this is signalled by an indicator
l ight, se e =>

E ectro-mechan-;cal power assist
The electro -me chanical po wer assist helps the driver
w hen steering.
The degree o f pow er assis t is electronically matched t o ve h ic le
speed .
The power stee ring system as sists the driver so that he can steer the
vehic le with reduced physica l effort.
P ower steering wil l not work if the engine is off. As a result, the
s te eri ng wheel wi ll be hard to turn .
& WARNING
If the system develops a problem , you must seek qualified profes ­
s ional assist ance .
0 Note
If there is an electronic ma lfunction, servotronic wi ll st ill function
li ke a conve ntio nal power stee rin g system, prov iding a constant
steering support force that is no longer proportionate to the vehicle
speed. This is most no ticeable when turni ng the s teering wheel at
l ow speeds (for examp le when parking), -more effort will be
r e q uired than usual. ._

Driving and environment
The first 1,000 miles ( 1 ,500 km) and
afterwards
New engine
The engine needs to be run-in during the first 1,000 miles
(1,500 km).
For the first 600 miles (1,000 kilometres):
Do not use full throttle.
- Do not drive faster than 3/4 of the top speed marked on
the speedometer.
- Avoid high engine speeds .
From 600 to 1,000 miles (1,000 to 1,500
kilometres):
- Speeds can gradually be increased to the max imum
permissible road or engine speed.
During and after break-in period
- Do not rev the engine up to high speeds when it is cold.
This applies whether the transmission is in N (Neutral) or
1n gear.
After the break-in period
- Do not exceed maximum engine speed under any
circumstances.
- Upshift into the next higher gear before reaching the red
area at the end of the tachometer scale=> page 12.
During the first few hours of driving, the engine's internal friction is
higher than later when all the moving parts have been broken in.
How well this break-in process is done depends to a considerable
extent on the way the vehicle is driven during the first 1,000 miles
(1,500 kilometres).
0 Note
Extremely high engine speeds are automatically reduced. However,
these RPM-limits were programmed for an engine well run-in, not a
new engine.
~ For the sake of the environment
Do not drive with unnecessarily high engine speeds - upshifting
early saves fuel, reduces noise and protects the environment .•
New tires
If your vehicle is running on new tires, drive particularly
careful for the first 350 miles (500 kilometres) after fitting.
& WARNING
New tires tend to be slippery and must also be "broken-in". Be
sure to remember this during the first 350 miles (500 kilometres).
Brake gently. Avoid following closely behind other vehicles or
other situations that might require sudden, hard braking.
:I

New brake pads
Remember that new brake pads do not have a full braking
effec t during the first 250 miles (400 kilometres) after they
are installed.
New brake pads have to be "burnished in" before they have optima l
grab=> &.
During the break -in period, you should avoid putting severe loads
on the brakes. Severe loads include, for example, sudden hard
braking, in particular at very high speeds or, for example, on moun ­
tain passes.

Catalytic converter
It is very important that your emission control system
(catalytic converter) is fu nctioning properly to ensure that
y o ur vehicle is running in an environmentally s ound
manner.
- Always use lead-free gasoline~ page 211, "Fuel supply".
- Never run the tank down a ll the way to empty.
- Never put too much motor o il in your engine~

Controls and equip­
ment Safety first Vehicle operation
Dri
ving and environm ent
The catalytic converter is an efficient "clean-up" device built into the
exhaust system of the vehicle . The cataly tic converter burns many
of the pollutants in the exhaust gas before they are re leased into the
atmosphere.
The exclusive use of un leaded fuel is critica lly important for the l ife
of the catalytic converter and proper functioning of the engine.
& WARNING
• Do not park or oper ate th e ve hi cle in are a s whe re the hot
exha ust sys te m may c ome in conta ct wi th dr y grass, bru sh , fu el
s pill or other mat eri al which can cau se a fi re.
• Do not app ly a dditi onal u nder co at ing or ru stpr oofing on or
near the exhau st m anifold , exh au st pipe s, cata ly tic convert er or
he at shi elds. During dri ving, the s ubstance use d f or und ercoa ting
c ould ov erheat an d ca u se a fire.
0 Note
• Be aware that just one tank fi lling with
le ad ed fuel wi ll a lready
seriously degrade the performance of the catalytic converter.
• Do not exceed the correct engine oil level =>
page 222.
• Do not drive until the fuel tank becomes completely empty. The
engine could misfire . Unburned fuel could a lso get into the exhaust
system and this could cause the catalytic converter to overheat .
• Do not turn off the igni tion wh ile the vehicle is moving.
• Do not continue to operate your vehicle under these conditions,
as otherwise fue l can reach the cata lytic converter. This could resu lt
in overheating of the converter, requiring its replacement .
• To assure efficient operation of the Emiss ion Control System:
- Have your vehicle maintained properly and in accordance with
the service recommendations in your Warranty
& Maintenance
booklet.

- Lack of proper maintenance as well as improper use of the
vehicle will impair the function of the emission con trol system
and could lead to damage.
Even when the Emission Control System is operating properly, the
exhaust gas can have a su lfur -like exhaust gas smell under some
operating states . This depends on the su lfur content of the fuel
being used. Using a different brand of fuel may he lp, or filling the
tank with lead-free super grade gasoline. •
Avoid damaging the vehicle
When you are driving on poor roads, or over curbs, steep ramps,
etc., make certain that low-lying parts such as spoilers and exhaust
system parts do not bottom out and get damaged.
This is especially true for vehicles with low-slung chassis (sports
chassis) and fully loaded vehicles. •
Operate your vehicle economically
and minimize pollution
General
Your personal style of driving will determine the economy
of your vehicle, as well as exhaust and noise levels.
Fuel economy, environmental impact, and wear on your engine,
brakes and t ires largely depend on three factors:
• your personal driving style
• operating condit ions
• technical limitations If
you anticipate what you need to do next and drive economically,
you can easily cut your fuel consumption by 10-15 percent . This
section will give you some tips on how you can he lp the environ­
ment and your pocketbook .
[ i ] Tips
The consumption estimates as published by ENVIRONMENTAL
PROTECTION AGENCY (EPA) and Transport Canada may not corre­
spond to your actua l consumption on the road, which will vary
depend ing upon vehicle load and speed, road and weather condi­
tions, trip length, etc. •
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are accelerating.
Avoid unnecessary accelerating and braking.
Vehicles use the most fue l when they are accelerating . If you antici­
pate what is going to happen next, you will need to brake less and,
thus, accelerate less. Let the vehicle coast whenever possible -for
example when you see that the next traffic light is red. •
Avoid full throttle
Driving at moderate speeds saves fuel and improves your
mileage.
- Try and keep well below your car's maximum speed.
Acce lerating gently reduces fuel consumption, engine wear, and
does not disturb the environment.
Fuel consumption, exhaust emissions and engine noise increase
disproportionately at high speeds. If you drive at approximately
three quarters of top speed, fuel consumption wil l be reduced by
9J,,

Cleaning and protection
General information
Regular care preserves vehicle value.
Any automobile is exposed to industrial fumes, corrosive road salt,
muddy dog feet, etc . A wel l cared for Audi can look like new many
years after purchase. Regu lar and correct ca re will contribute to
maintaining the beauty and value of your Audi.
Furthermore, good care may be a conditi on for substantiating a
war ranty claim should co rros ion d amage or p aint defec ts occur .
Your authorized Audi dealer has a variety of dedi cated vehicle- care
product s
and can advise whic h ones to use for cleaning the exterior
and interior of your vehicle.
Whether you use p roducts recommended by Audi or other commer ­
cially availab le cleaning agents , please make sure you apply them
correctly.
& WARNING
• Cleaning agents may be poisonous . Keep them out of the reach
of ch ildren .
• Heed all caution label s.
• Alway s read directions on the contai ner before u sing any
produ ct. Follow the di rection s carefull y.
• Most chemical cleaner s are concentrated and have to be
d iluted .
• Use s pot removing fluids only in well ventilated area s.
• Do not us e gasoline , ker osene , die sel fuel , nail polish rem over
or oth er volatile fluid s. They may be toxi c, flammable or ha zardous
in other way s. Do n ot w ash, wa x or dry the vehicle w it h the igni ­
tion on or the engine running.
& WA RNIN G (conti nued)
• Do not clean the under side s of chassis , fe nder s, wheel cove rs,
etc . without protecting your hands and arm s. You may cut yourself
on sha rp -edg ed metal part s.
• Moisture and ice on brakes may impair braking eff iciency
=> page 186 , "General info rm ation ". Test the brake s carefully each
time you wa sh the vehicle.
~ For the sake of the environment
Se lect only environmenta lly friend ly c leaning products . Leftover
clean ing products should not disposed of in the household waste. •
Care of exterior
Washing
Frequent washing protects the vehicle.
Th e best protection against envi ronmental influences is frequent
washing and waxing .
H ow often t his is required depends on:
• H ow much the vehic le is used
• Where the vehicle is pa rked (garage, in the open under t rees,
etc.)
• The seasonal and weather conditions
• Environmental influences
T he longer bird droppings, insects, tree resin, road a nd industrial
grime, tar, soot, road salt and other materials remain on the vehicle
p aint, the more lasting their dest ructive effects will be . _,,,

T he best way to remove snow from windows and mirrors is to use a
brush . Use a non -abrasive
pla stic ice scraper -better still, a spray
deicer -to remove
ice from w indows and mirrors .
The windows must not be cleaned with insect remover or wax since
these can inter fere with the function of the w inds hie ld w iper blades
(chatter).
Oil, grease o r sil icone residue can be removed with
glass cleaner or
s ilicone remover . However, wax residue requires the use of a
spec ially for mulated solvent . Please contact your Audi dealer for
advice on safe products for wax removal.
Windows should also be c leaned on the inside at regular intervals .
Never dry windows with the same chamois that you use to dry
painted surfaces . Wax residue on the chamois can impair vision
t hrough the windows.
& WARNING
• The windshield mu st not be treated with water -repellent mate ­
rials. They c an incre ase gl are under poor v isibility conditions such
a s wetne ss, darkne ss, or when the sun i s low on the hori zon. In
addition , they can cause the wind shield wipers to chatter .
