Description
The indicator lights in the instrument cluster
blink or turn on. They indicate functions or
m alfunctions
c::> .&. .
Messages may appear with some indicator
lights. A warning signal will sound at the
same time . The messages disappear again af­
ter a short t ime. To display a message again,
press the
I S ET I bu tton c::> page 11 . If several
malfunction s occur, each of the indicator/
warn ing lamps will be d isplayed in succession
for about two seconds at a time.
Some ind icators ligh ts in the display can turn
on in several colors.
A WARNING
- Failure to heed warning lights and other
important vehicle info rmation may result
in serious personal injury o r vehicle dam­
age.
- Whenever sta lled or s topped for repa ir,
move the vehicle a safe dis tance off the
road, stop the engine, and turn on the
emergency flasher
c::> page 53.
- T he engine compartment of any motor
vehicle is a poten tially hazardous a rea.
Before you check anything in the engine
compartment, stop the engine and let it
cool down. Always exercise extreme ca u­
t ion when working under the hood

Overview
Some ind icator lights turn on briefly to check
the function of that system when you switch
the ignition on . T hese systems are marked
with a./ in t he followi ng tab les. If one of
these ind icator lights does no t turn on, there
is a malfunction in that system.

180 Driving and en vironm ent
8_ 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 re­
store the full braking effect.
(D Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys­
tem can be severely damaged by driving
through wate r.
@ Tips
- Check the depth of the water before dr iv­
i ng through it.
- Do not stop the veh icle, dr ive in reverse
or switc h the engine off when driving
t hr ough water.
- Keep in mind that oncoming vehicles
may c reate waves that raise the water
l evel and make it too deep fo r you r vehi­
cle to dr ive through safely.
- Avoid dr iving thro ugh salt water because
i t can ca use corrosion.
Warming up and
cooling down
-
By carefully warming up and cooling down
your ve hicle, you can he lp ensure that it is not
overstressed unnecessarily dur ing sporty driv ­
ing.
When warming up, the vehicle is d riven at a
maximum engine speed of 6000 RPM in order
to raise the engine oi l temperature to a mini ­
mum of 140
°F (60 °(). The tires also only
reach their full road holding capability once
they have warmed up .
The cooling fan can contin ue to run in your ve­
h icle after the engine is switched off. Howev­
er, driving the vehicle to cool it down is part ic­
ularly important. During sporty driving, the
engine and brakes, the ex ha ust system, and
the transm ission all become extremely hot.
B efore you park the vehicle, you shou ld drive it for a few miles/kilometers at
light load in
the low rpm range to allow it to cool down.
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 c:> page 190,
Fuel supply.
.. Never run the tank down all the way to emp­
ty .
.. Never put too much moto r oil in your engine
c:> page 199, 't::71 Adding engine oil .
.. Never try to p ush- or tow -sta rt yo ur vehicle.
The catalytic converter is an efficient "clean­
up" device bu ilt into the exhaust system of
t h e vehi cle. The cata lytic conve rter bu rns
many of the pollu tan ts i n t he exh aust gas be­
f ore they are re lease d into the atmosphere.
T he exclusive use of unleaded fue l is critica lly
impor tant for the life of the catalyt ic convert­
er and prope r fu nct ion ing of the engi ne.
8_ WARNING
- T he temperature of the exhaus t system
is high, both when driving and after stop ­
p ing the engine.
- Never touch the exhaus t tail pipes once
they have become hot . This cou ld result
in burns .
- Do not park or operate the vehicle i n
areas where the hot exha ust system may
come in contact with dry grass, brush,
fue l spill or other material wh ich can
cause a fire.
- Do not app ly additional undercoating or
rustproofing on or near the exhaust
manifold, exhaust pipes, catalytic con­
ver ter or heat shields . Dur ing driv ing, the
substance used for undercoating could
overheat and cause a fire.

(D Note
-Be aware that just one tank fi lling with
le ad ed fuel will already seriously de­
grade the performance of the catalytic
converter.
- Do not exceed the correct engine oil leve l
c>page 199.
-Do not drive until the fuel tank becomes
complete ly empty. The engine could mis ­
fire. Unburned fuel could also get into
the exhaust system and this could cause
the catalyt ic converter to overheat.
- Do not turn off the ignition while the ve­
hicle is moving .
- Do not continue to operate your vehicle
under these condit ions, as otherwise fuel
can reach the catalytic converter. This
could result in overheat ing of the con­
verter, requ iring its replacement.
- To assure efficient operat ion of the Emis­
s ion Control System:
- Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
&
Ma intenance booklet.
- Lack of proper maintenance as well as
improper use of the vehicle will impa ir
the funct ion of the emission control
system and could lead to damage .
@) For the sake of the environment
Even when the Emission Control System is
operating properly, the exhaust gas can
have a sulfur-like exhaust gas smell under
some operating states. This depends on
the s ulfur content of the fuel being used.
Using a d ifferent brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline .
Shutting down vehicle
If you would like your veh icle to remain inop­
erat ive for a longer period of time, contact an
Audi or other specialized dealer. They can ad­
vise you on necessary precautions e .g. corro ­
sion prevention, maintenance and storage.

Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex ­
haust and noise levels.
Fuel economy, environmenta l impact, and
wear on your engine, brakes and tires largely depend on three factors:
- your personal d riving style
- operating conditions
- technical limitat ions
If you ant ic ipate what you need to do next and
drive economically, you can easily cut your
fuel consumpt ion by 10-15 percent . This sec­
tion w ill give you some tips on how you can
help the env ironment and your pocketbook.
(D Tips
The consumption estimates as published
by ENVIRONMENTAL PROTEC TION AGENCY
( E PA) and Transpo rt Canada may not cor re­
spond to your actual consump tion on the
road, which will vary depending upon vehi­
cle load and speed, road and weather con ­
dit ions, trip 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 most f uel when they a re ac­
ce lerat ing. If you ant icipate what is going to
happe n next, you will need to brake less and,
th us, acce lerate less . Let the vehicle coast
whenever possible -for examp le when you see
that the next traff ic light is red.

Fewer short trips
Fuel consumption will always be relatively
high on short trips.
11-Try to avoid driving short distances with a
cold engine.
The engine and catalytic converter have to
reach their optimal
operating 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 miles
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 m iles (4 km),
the engine is at its proper operating tempera­
ture and fue l economy has reached a normal
l eve l. So you can see that you should avoid
short trips whenever possible.
The
outside temperature is also critical in this
regard. Your car consumes more fuel in the
winter than in the summer.
