On-Board Diagnostic system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) in the instrument cluster
=;,
page 12, fig. 7 is part of the On-Board Diagnostic (OBD II) system.
The warning/indicator light illuminates when the ignition is switched
on and goes out after the engine starts and the idle has stabilized.
This indicates that the MIL is working properly.
If the light does not go out after the engine is started, or illuminates
while you are driving, a malfunction may exist in the engine system.
If the light illuminates, the catalytic converter could be damaged.
Continue driving
with reduced power (avoiding sustained high
speeds and/or rapid accelerations) and have the condition corrected.
Contact your authorized Audi dealer .
If the light illuminates , the electronic speed limiter may also be
malfunctioning. For more information=;,
page 26, "Electronic speed
limiter".
An improperly closed fuel filler cap may also cause the MIL light to illuminate

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:

•
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

• 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
( c a ta lytic co n verter) is functionin g proper ly to e nsure
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
and minimize pollution

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. •

Fuel supply and filling your fuel tank
In order to fill the tank properly while protecting the environment,
please follow this refueling procedure carefully.
& WARNING
Under normal operating conditions, never carry additional fuel
containers in your car. Gas canisters and other containers used to
transport fuel can be dangerous. Such containers, full or empty,
may leak and could cause a fire in a collision. If you must transport
fuel to use for your lawn mower, snow blower, etc., be very careful
and always observe local and state laws regarding the use, trans­
portation and storage of such fuel containers. Make certain the
container meets industry standards (ANSI/ASTM F852 -86).
0 Note
Never drive your vehicle until the fuel tank is completely empty . The
irregular supply of fuel can cause misfiring. Gasoline could enter the
exhaust system and damage the catalytic converter. •
