off by pressing it again.
If the engine does not start immediately, stop trying after 10 seconds
and then try to restart the engine about 30 seconds later.
After a cold engine is started, there may be a brief period of increased
noise because oil pressure must first build up in the hydraulic valve
adjusters. This is normal and not a cause for concern.

Corrosion
T he re may be a te ndency fo r d irt to build u p on the bra ke pads and
co rrosion to form on the d iscs if the car is not dr iven reg ularly o r only
for short trips with litt le use of the bra kes .
If the brakes a re not used freq uen tly, or if co rrosion has formed o n
the discs, it is advisable to clean off the pads and discs by braking
fir mly a few times from a mode rat ely h igh spee d~ & .
Faults in the brake system
If yo u sh ou ld noti ce a sudden increase in b rake peda l trave l, then one
of the two brake circu its may have failed~& .
Low brake fluid level
Ma lfunctions can occ ur in t he brake system if the brake fluid level is
t oo low. The bra ke f lu id level is moni tore d elec tron ically.
Brake lin ing wear status
Brake lin ing wear may be checked by v isua l inspect ion of the condi­
tion of the brake pads throu gh the open ings in the whee l.
If neces­
sary, the whe el may be removed fo r thi s insp ection~
page 320,
"Changing a w hee l".
& 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 cau se an accident!
• Before descending a steep grade, reduce speed and shift trans­
mission into a lower gear or lower driving range. 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 condition s such as
passing through water , driving in heavy rain or after washing the
& WARNING (co ntinued )
vehicle, the effectiveness of the brakes can be reduced . In winter,
ice can ac cumulate on the brake pads, linings, dis cs and drums.
Carefully apply brakes for a test. Brakes will dry and ice coatings
will be cleaned off after a few careful brake appli cations.
• Driving for an extended period of time on salt-covered roads
without u sing your brakes can also affect braking efficiency . Clean
off accumulated salt coating from b rake discs and pads with a few
careful brake applic ations.
• If you damage the front spoiler, or if you install a different
spoiler, be sure the air flow to the front brakes i s 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 di stance. Avoid driving the
vehicle and have it towed to the nearest authorized Audi dealer or
qualified workshop.

& WARNING
• Never let the vehicle 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 mu st be pressed considerably harder to
make up for the lack of booster assistance. •

New brake pads
- -
Remem ber th at new brake pads do not have a full braking
e ffe ct du ring the first 250 mi les (400 ki lo mete rs) afte r they
are in sta lle d .
N ew br ake pads have to be " burnishe d in" before they have op tim al
grab~ &-
Dur ing the break-in period, you sho uld avoid putting severe loads on
the brakes . Severe loads include, for example, sudden ha rd bra king,
in part icu lar at very high s peeds o r, for example, on mountain passes .
& WARNING
New brake pads don't have the best stopping power and must be
" broken-in " during the in itial 100 to 150 miles (150 to 200 kilo ­
meters) of normal city driving. You can compensate for this by
pressing the brake pedal mor e firmly . This also applies later when
new pads are installed. n
Avoid damaging the vehicle
When yo u are driving on poor roads, or over c urbs, steep ramps, etc.,
ma ke ce rtain that low-lying pa rts su ch as spoilers and exhaust system
parts do not bottom out and get damaged .
This is es peciall y tr ue for veh icle s wi th low-slung chass is (sports
chassis)" and fully loaded vehicles. •
Driving through water on roads
Note the following to avoid vehicle damage w hen drivi ng through
water, fo r examp le on floode d roa ds:
Controls and equip­
ment Safety first Vehicle operation
•
The wate r must not be any higher than the bottom of the vehicle
body .
• Do not drive faster than wa lking speed.
& WARNING
After driving through water , mud , slush , etc ., the brakes may be
slow to take effect because of wet brake rotors and pads . Dry the
brakes first by braking carefully to resto re the full braking effect.
0 Note
Vehicle components such as the engine, transmiss ion, suspension or
ele ct ric al sy stem can be severe ly d amaged by driv ing thro ugh wa ter.
[ i ] Tips
• C heck the de pth o f th e wate r before driving thr oug h it.
• Do not stop the vehicle, drive in reverse or switch the engine off
w he n dr iving throug h wate r.
• Keep in m ind that oncoming vehicles may c reate waves t hat raise
t he water leve l and make it too deep fo r yo ur vehicle t o drive thr oug h
safely.
• Avoid drivi ng through sal t wa ter because it can cause corros io n.
Catalytic converter
It is very important th at your emission control s ystem

th at y our ve hicl e is ru nn in g in an en vir onm entally sound
m ann er.
- Alwa ys use lead- free g asoline=> p ag e 274, "Fuel sup ply".
- Never ru n the tan k down a ll the way to empty . .,
Vehicle care Do-it-yourself service Technical data

Driving and environment
- Never put too much motor oil in your engine=> page 284,
"Adding engine oil~".
- Never try to pus h- or tow-sta rt your vehicle.
The catalytic converter is an efficient "clean-up" dev ice built into the
exhaust system of the vehicle. The catalytic converter burns many of
the pollutants in the exhaust gas before they are released into the
atmosphere.
T he exclusive use of unleaded fuel is c riti cal ly import ant for the life of
the catalytic converter and proper funct io ni ng of the eng ine.
& WARNING
• Do not park or operate the vehicle in areas where the hot
exhaust sy stem may come in conta ct with dry gras s, brush, fuel
spill or other material which can cause a fire.
• Do not apply addit ional undercoat ing or rustproofing on or
near the exhaust manifold , exhau st pipes , catalytic converte r or
heat shield s. During driving, the sub stan ce u sed f or under coating
c ould o ve rheat and cause a fire.
0 Note
• Be aware that just one tank filling with leaded fuel w ill already
ser iously degr ade the performance of the ca talytic co nve rter.
• Do not exceed the correct engine oil level =>
page 284.
• Do not dr ive until the f uel tank becomes com plete ly empty . T he
engine could misfire . Unburned fuel cou ld also get into the ex ha ust
system and t his co ul d cause t he ca talyt ic converter to ove rheat .
• Do not turn off the ignition while the vehicle is moving.
• Do not continue to operate your vehicle u nder these conditions, as
otherwise f uel can reac h the c ata ly tic conve rter. This co uld res ult in
over heat ing of the converter, requir ing its replacement.
• T o ass ure eff icien t operat ion of the Emission Cont rol System: -
Have your vehicle maintained properly and in accordance with
th e se rvice reco mmend ations in your W arran ty
& M ain ten ance
booklet.
- Lack of prope r main ten anc e as well as imp roper use of the
veh icle w ill impair the fu nction of the emission control system and
c o uld l ead to d amage.
~ For the sake of the environment
Even when the Emission Contro l System is operat ing proper ly, the
exhaust gas can have a sulfur-like exhaust gas smell u nder some
operating states. This depends on t he sulfur content of the fue l being
used . Using a different brand of fuel may help , o r fil lin g the tank with
lead-free supe r grade gasoline. •
Operate your vehicle economically

• operat ing cond itions
• technical lim itations
If you an ticipa te wh at yo u nee d to do nex t and drive e co nom ically,
you can easily cut your fuel consumption by 10- 15 percent. This

Driving and environm ent
------------------------------------------------'
[I) Tip s
The consumption estimates as published by ENV IRONMEN TA L
PROTECTION AGENCY (EPA) and Transport Canada may not corre­
spond to your actual consumption on the road, wh ich w ill vary
depending upon vehicle load and speed, road and weather conditions ,
trip length, etc. •
Drive smoothly :1nd keep a Lookout ahead
Vehicles use the most fuel when they are accelerating .
-Avoid unnecessary accelerating and braking.
Vehicles use the most fuel when they a re 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 l ight 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 .
Accelerating 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 approx imately three
quarters of top speed, fuel consumption will be reduced by one half.
Never dr ive faster t han the posted speed limit and weather condi­
tions permit. •
Controls and equip­
ment Safety first Vehicle operation
Reducing unnecessary idling
Even when your car is just idling it burns up fuel.
-
Shut the engine off when you are not driving the vehicle .
- Do not warm up the veh icle by letting the engine run at
idle.
It makes sense to shut off the engine in traffic jams, when wa iting for
trains to pass at railroad crossings, or at traffic lights that have long
wa its on red . Turn ing the engine off for just 30-40 seco nds saves
mor e fuel than is burned starting the engine again .
It takes a long t ime for the engine to wa rm up fully when it is run ning
at idle. However, wear and noxious emissions are espec ia lly high
when the eng ine is wa rming up. So you should dr ive away as soon as
you start the engine and avoid running at hig h rpms while the engine
is still warm ing up.
0 Note
Do not leave engine idling unattended after starting . If warning
lights should come on to indicate improper operation, they would go
unheeded. Extended idling also produces heat, which could result in
overheat ing or other damage to the vehicle or othe r property.
Regular mai n _t_ e_ n_a_ n_ c_e ___________ _
A badly tuned engine unnecessarily wastes a lot of fuel.
-Have your vehicle serviced at regular intervals .
By having you r vehicle regularly serviced by an authorized Audi dealer
helps to ensure that it runs properly and economically . The condit ion
of your vehicle not only affects its safety and ability to ho ld its val ue,
it also affects
fu el con sumpt ion.

Vehicle care Do-it-yourself service Technical data

Driving and environment
The amount of oil used is related to engine load and speed.
It is normal for the oil consumption of a new engine to reach its
lowest value after a certain mileage has been driven.
You must drive your vehicle about 3,000 mi les (S,000 kilometers)
before you can properly assess oil consumption.
Th is also applies to fuel consumption and engine output .
0 Note
• 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 w ill
impair the function of the emission control system and could lead to
damage.
• Do not alter or remove any component of the Emission Control
System unless approved by the manufacturer.
• Do not a lter or remove any device, such as heat shields, switches,
ignition wires, valves, which are designed to protect your vehicle's Emission Contro l System and other important vehicle components .•
Fewer short trips
Fuel consumption will always be relatively high on short
trips .
-Try to avoid driving short distances with a cold engine.
The engine and catalytic converter have to reach their optimal oper·
ating temperature
to reduce fuel consumption and noxious emis ­
sions effectively.
Just after starting, a cold engine in a mid-size car only achieves a fuel
economy of 6-8 m iles per gallon (30-40 l/100 km) . After about a half
a mile, fuel economy climbs to 12 mpg (20 l/100 km). After about
2.5 mi les (4 km), the engine is at its proper operat ing temperature and fuel economy has reached a normal
level. So you can see that you
should avoid short trips whenever possible .
The
outside temperature is also crit ical in this regard . Your car
consumes more fue l in the winter than in the summer. •

0 Note
• Never use chemical so lvents (e.g. lig hte r fluid, turpentine), waxes,
shoe po lish or simi lar p roducts on Alca ntara ® surfaces .
• To avo id damage, have stubborn stains removed by a commerc ia l
cleaning specialist .
• Do not use brushes, stiff sponges or sim ila rly abrasive cleaning
aids. •
Safety belts
Only well-maintain ed safety belts work reliably when
needed .
-Keep be lts clea n.

Heavily soiled safety belts may no t re tract p roper ly .
& WARNING
Damaged safety belts can break in a crash.
• Anything that might damage your safety belts could mean
that you and your passengers would not be adequately protected
in an a ccident.
• Safety belt performance depends on correct installation. Never
remove belts from the vehicle to clean them.
• Do not use chemical cleaning agents , bleach or dyes. They have
corro sive properties which weaken the webbing .

entire eng ine compa rtment and plenum pane l sho uld be thoroug hly
cleaned at the end of w inter and retreated to prevent sa lt damage . At
the same time, the underside of the vehicle should be washed as we ll.
If the eng ine co m par tment is clea ned at any time wi th grease
