,&_ WARNING
- Always observe the warning in
¢ page 208, Engine compartment, be­
fore opening the hood and checking the
engine coolant level.
- 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 so that you cannot hear or
see any steam or engine coolant .
(D Note
-Mounting additional lights or accessories
in front of the air inlets reduces the cool­
i ng effect of the radiator. At h igh outside
temperatures or high engine load, the
engine could overheat.
- The front spo iler has been designed to
properly distribute the cooling air when
the veh icle is moving. If the spoiler is
damaged, this could reduce the cooling
effect and the engine could then over­
heat. Ask your authorized Audi dealer for
assistance.
Tachometer (engine rev counter)
The tachometer indicates the engine RPM
(revolutions per minutes).
If engine RPM d rops be low 1,500 , you should
downshift to the next lower gear. The red area
at the end of the scale indicates maximum
permissible engine RPM after the break-in pe­
riod. Before reaching this area, move these­
lector lever to position D/S or ease your foot
off the accelerator pedal.
(D Note
The tachometer needle@¢ page 10,
fig . 3
shou ld only briefly be in the red
zone: you could damage your engine! The
beg inning of the red zone varies depend­
ing on the engine.
@) For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise.

On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) II in
the instrument cluster 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 stabi lized .
This indicates that the MIL is working proper­
l y.
If the light does not go out after the engine
is started, or illuminates while you are driv­
ing, a malfunction may exist in the engine sys- tern.
If the
light illuminates, the catalytic con­
verter could be damaged.
Continue driving
with reduced power (avoid­
ing sustained high speeds and/or rapid accel­
erations) and have the condition corrected.
Contact your authorized Audi dea ler.
If the light illuminates, the electronic speed
limiter may also be malfunct ioning. For more
information
q page 31, El ectronic speed
limiter .
An improperly closed fuel filler cap may also
cause the MIL light to illuminate
~page 212.
On-Board Diagnostics
Fig. 18 Locat ion of Data L ink Connector (DLC)
On-Board Diagnostics monitors the compo­
nents of your em ission control system . Each
monitored component in your engine system
has been assigned a code . In case o f a mal­
function, the component will be identified
and the fault stored as a code in the control
module memory.
T he MIL light may also illuminate if there is a
leak in the on-board fuel vapor recovery sys­
tem.
If the light illuminates after a refueling,
stop the vehicle and make sure the fuel filler
cap is properly closed
q page 212.
In order to make an accurate diagnosis, the
stored data can on ly be displayed using spe ­
cial diagnostic equipment (generic scan tool
for OBD).
In order to connect the special diagnostic
equipment, push the plug into the Data Link ..,.

A 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 brak ing effect.
([) 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 switch the engine off when driving
th rough water.
- Keep in mind that oncoming vehicles
may create waves that raise the water
level and make it too deep for you r vehi­
cle to drive th rough safely.
- Avoid dr iving through sa lt water because
i t can ca use corrosion.
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.
11-Always use lead-free gasoline q page 210,
Fuel supply .
"'" Never run the tank down a ll the way to
empty.
11-Never put too much motor oil in your en-
gine
q page 220, ~ Adding engine oil .
11-Never try to push -or tow-start your veh icle .
The catalytic converter is an efficient "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 .
Drivin g and en vironm ent 193
The exclusive use of unleaded fuel is critically
important for the life of the catalytic convert­
er and proper funct ion ing of the engine.
A WARNING
-
- 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 mate rial wh ich can
cause a fir e.
- Do not apply additional undercoating or rustp roof ing on or near the exhaust
manifold, exhaust pipes, catalytic con­
ve rter or heat shields. During driv ing, the
substance used for undercoating co uld
overheat and cause a fire.
(D Note
- Be aware that just one tank filling with
leaded fu el w il l already ser iously de­
gra de the performance of the catalytic
c onverte r.
- Do not ex ceed t he cor rect eng ine oil level
qpage 220.
- Do not drive until the fue l tank becomes
comple tely empty. The engine co uld m is­
fire . Unburned fuel could also get in to
the exhaust system and th is co uld cause
the catalytic converter to overheat .
- Do not turn off the ignition while the ve ­
hicle is moving.
- Do not continue to ope rate your veh icle
unde r these conditions, as otherwise fuel
can reach the catalytic converte r. T his
cou ld result in overheating of the con­
verter, requir ing its replacement.
- To assure efficient operation of the Emis ­

(D Note
Do not leave engine idling unattended af­
ter starting . If warning lights should come
on to indicate improper operation, they
would go unheeded. Extended idling also
produces heat, which could result in over­
heating or other damage to the vehicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel .
.,. Have your vehicle serv iced at regular inter-
vals .
By having your vehicle regularly serviced by an
authori zed Audi dealer helps to ensure that it
runs properly and economically . The condition
of your vehicle not only affects its safety and
ab il ity to hold its value, it also affects
fuel
consumption.
Check your oil each time you fill your tank.
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 miles
(5,000 kilometers) before you can properly
assess oi l consumption.
This a lso applies to fuel consumption and en­
g ine output .

-Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
& Main­
tenance booklet. Lack of proper mainte ­
nance as well as improper use of the ve­
hicle will impair the function of the
emission control system and could lead
to damage.
Driving and environment 195
- Do not alter or remove any component of
the Emission Control System unless ap­
proved by the manufacturer .
- Do not alter or remove any device, such
as heat shields, switches, ignition wires,
valves, which are designed to protect
your vehicle's Emission Control System and other important vehicle compo­
nents .
Fewer short trips
Fuel consumption will always be rela tively
high on short trips .
.,. Try to avoid driving short distances with a
cold engine.
The engine and cata lytic converter have to
reach their opt imal
operating temperature to
reduce fuel consumpt ion and noxious emis­
sions effectively .
Just after starting, a co ld 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 miles (4 km),
the engine is at its proper operat ing tempera­
ture and fuel economy has reached a normal
level. So you can see that you should avoid
short trips whenever possible.
T he
outside temperature is also cr itical in th is
regard. Your car consumes more fue l in the
winter than in the summer.
