12 Instrum ent s and w arn ing /indic ato r light s
-Never open the engine hood if you see or
hear steam, or if you see engine coolant
dripping from the engine compartment.
You could burn yourself . Let the engine
cool off first until you can no longer see
o r hear steam or coo lant escaping.
@ Note
- Mounting additional lights or accessories
i n front of the a ir inlets reduces the cool­
i ng effect of the rad iator . At h igh outside
temperatures or high eng ine load, the
engine could overheat.
- The front spo iler has been designed to
proper ly distribute the cooling air when
t h e ve hicle is moving.
If the spoiler is
dam aged, th is co uld red uce the cooling
effect and the engine co uld then over­
heat . Ask your authorized Audi dea ler for
assistance .
Tachometer (engine rev counter)
The tachometer indicates the engine RPM
(revolutions per minutes).
If engine RP M drops be low 1,500, yo u should
downshift to the next lower gear. The red a rea
at the end of the sca le indicates maximum
perm iss ib le engine RPM after the break-in pe­
riod. Before reaching this area, move these­
lector lever to position D/S (Drive) or ease
your foot off the accelerator pedal.
(D Note
The tachometer needle should on ly br iefly
be in the red zone: you could damage your
engine! The beginn ing of the red zone var­
ies depending on the engine .
@ For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise.
Fuel gauge
The fuel gauge only works when the ignition is
on .
If the fuel level d rops below 2 . 6 ga llons (10 liters), the bottom LED turns red and the
indicator light
Em turns on
¢ page 22. The
bottom LED blinks red when the fuel level is
very low.
T he possible range based on the current fuel
level is shown in tab@<=>
page 24, fig . 4 .
(D Note
Never run the tank completely dry. An ir ­
r egular supply of f uel can cause engine
misfiring and fuel could enter the ex ha ust
system . The catalytic converter could then
overheat and be damaged.

Winter tires
When dr iving in the win ter, yo ur vehicle wi th
all-wheel drive has an advantage, eve n with
regular tires. In winter road conditions it may
be advisable to mount winter tires (or all-sea­
son tires) for improved driveability and brak­
ing : these tires must be mounted on
all fou r
w heel s.
See also¢ page 255, Winter tires .
Tire chain s
Where tire chains are mandatory on certain roads, this norma lly also app lies to ve hicles
with all-wheel drive¢
page 256, Snow
chains .
Replacing wheel s/tire s

Catalytic converter
Appl ies to vehicles: with gasoline e ngin e
It is very important that your emission con­
trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner .
.. Always use lead-free gasoline¢ page 215,
Fuel supply .
.. Never run the tank down all the way to emp-
ty .
.. Never put too much motor oil in your engine
¢ page 229, Adding engine oil .. Never try to push- or tow-start your veh icle.
The catalytic converter is an eff ic ient "clean­
up" device built into the exhaust system of
the vehicle. The catalyti c converter burns
many of the pollutants in the exhaust gas be­
fore they are released into the atmosphere.
The exclus ive use of unleaded fuel is cr itically
important for the l ife of the cata lytic convert­
e r and proper functioning of the engine.
A WARNING
T he temperature of the exhaust system is
high, both when driving and after stopping
the engine .
- Never touch the exhaust tail pipes once
they have become hot. This could result
in burns.
- Do not park or operate the vehicle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fuel spill or other material which can
cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust
man ifold, exhaust p ipes, catalytic con­
verter or heat shields . During driving, the
substance used for undercoating cou ld
overheat and cause a fire.
@) Note
- Be aware that just one tank f illing with
leaded fuel will al ready seriously de­
grade the perfo rmance of the cata lytic
conve rter. -
Do not exceed the correct engine oil level
¢page 229.
-Do not drive until the fue l tank becomes
completely empty . The engine co uld m is­
fire . Unburned fuel could also get into
the exhaust system and this cou ld cause
the catalytic converter to overheat.
- Do not switch off the ignition while the
vehicle is mov ing .
- Do not continue to ope rate your vehicle
under these conditions, as otherwise fuel
can reach the catalyt ic converter. Th is
cou ld result in overheating of the con­
verter, requir ing its replacement .
- To assure efficient operation of the Emis­
sion Control System:
- Have you r vehicle maintained p roperly
and in accordance w ith the service rec­
ommendations in your Warranty & Maintenance book let.
- Lack of prope r maintenance as we ll as
improper use of the vehicle wi ll impair
the function of the em ission contro l
system and could lead to damage.
@) For the sa ke of the en vironment
Even when the Emission Control System is
ope rat ing properly, the exhaust gas can
have a sulfur-like exhaust gas smell under
some operat ing states. This depends on
the sulfur content of the fuel being used .
Usi ng a different brand of fuel may help,
or f illing the tank with lead-free super
grade gasoline.
Diesel particulate filter
Applies to vehicles: with diese l eng ine
The diesel part icu late filter filters nearly all of
the soot pa rticles out of the exhaust . T he fil­
te r cleans itself automat ica lly unde r no rma l
dr iv ing cond itions . If the filte r cannot clean it­
self (for example, because you are on ly driving
short distances), the filter becomes clogged
with soot and the

204 Driving and en vir onm ent
The consumption estimates as published
by ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, which will vary depending upon vehi ­
cle load and speed, road and weather con­
ditions, tr ip length, etc .
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
• Avoid unnecessary accelerating and braking.
Vehicles use the mo st fuel when they are ac­
celerating . If you anticipate what is go ing to
happen next, you will need to brake less and,
thus , accelerate less. Let the vehicle coast
wheneve r poss ible -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 max imum
speed .
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the
environment .
Fuel consumption, exhaust emissions and en­
g ine no ise increase d isproportionately at high
speeds. If you dr ive at approximately three
quarters of top speed, fue l consumption will
be reduced by one half. Neve r dr ive faste r
than the posted speed limit and wea ther con­
d itions permit.
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
• Shut the engine off when you are not dr iv ing
the vehicle. •
Do not warm up the vehicle by letting the
engine run at id le .
T he id ling phase is automatically red uced for
vehicles with the Start/Stop system . It is effi ­
cient to switch off the engine in vehicles with ­
out the Start-Stop -System when stopp ed at
railroad crossings and long red lights. Tu rning
the engine off for jus t 30-40 seconds saves
more fuel than is burned by starting the en-
. . gme again .
It takes a long time for the eng ine to warm up
fully when i t is running at idle. However, wear
and noxiou s emissions are espec ially high
when the eng ine is warm ing up . So you should
drive away as soon as you start the engine and
avo id running at high rpms while the engine is
still warming up.
W Note
Do not leave engine idling unattended af­
ter start ing . If wa rning lights should come
on to indicate improper operation, they
wo uld go unheeded . Ex tended idling also
produces heat, wh ich could res ult in ove r­
heating or other damage to the ve hicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
• Have your veh icle serviced at reg ular in ter -
vals .
By having your ve hicle regu la rly se rviced by an
Audi dealer he lps to ensu re tha t it runs p rop ­
erly and economically . The condition of your
vehicle not only affects its safety and ability to
ho ld its va lue, it also affects
fuel con sump­
tion .
Check your oil e ach time you
fill y our tank.
The amount of o il used is re lated to engine
load and speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a certa in
mileage has bee n driven . ..,.
