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 21. T
he
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@<=>
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 haust
system . The catalytic converter could then
overheat and be damaged.

200 Driving and en vir onm ent
Catalytic converter
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 220,
Fuel supply.
• Never run the tank down all the way to
empty .
• Never put too much motor oil in your en-
gine ¢
page 230, 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 catalytic converter burns many of the pollutants in the exhaust gas be­
fore they are released into the atmosphere.
The exclusive use of unleaded fuel is critically
important for the life of the cata lytic conve rt­
e r and proper functioning of the engine.
& WARNING
-
- Do not park o r 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 could
overheat and cause a fire .
@ Note
-Be aware that just one tank filling with
leaded fuel will already seriously de­
grade the performance of the catalytic
conve rter .
- Do not exceed the correct engine oil level
¢ page 230.
-Do not drive until the fuel tank becomes
completely empty. The eng ine could mis­
fire . U nburned f uel could a lso get into the exhaust system and this co
uld cause
the cata lytic converter to overheat .
- Do not switch off the ignition while the
vehicle is moving .
- Do not continue to ope rate your veh icle
under these conditions, as otherwise fuel
can reach the catalytic converter. This
cou ld result in overheating of the con­
verter, requir ing its replacement.
- To assure efficient operation of the Emis ­
sion Control System:
- H ave your vehicle maintained properly
and in accordance w it h the service rec­
ommendat ions in your Warranty &
M ain tenance book let.
- L ack of prope r maintenance as we ll as
improper use of the vehi cle will impair
the function of the em iss ion contro l
system and could lead to damage .
@ For the sake of the environment
Even when the Emiss ion Control System is
operat ing proper ly, the exha ust gas can
have a sul fur -li ke exhaust gas smell under
some operating states . This depends on
the sulfur content of the fuel being used .
Using a different brand of fue l may help,
or f il li ng the tank with lead-free super
grade gasoline .
Avoid damaging the
vehicle
When you are d rivi ng on poor roads, or over
c u rbs, steep ramps, etc., ma ke certai n that
low- ly ing parts s uch as spoilers and exha ust
system parts do not bottom o ut and get dam ­
aged.
T his is espe cially true for ve hicles with low­
s lung chassis (spor ts chassis)* and fully load­
ed vehicles .
