Instrument s and warning /indicator lights 11
A WARNING
- Always observe the warning in
c::> page 214 , before 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
ing effect of the rad iator. At high outside
temperatures or high eng ine load , the
engine could overheat.
- The front spoiler has been designed to
properly distribute the cooling air when
the veh icle is moving .
If the spoiler is
damaged , this cou ld reduce the cooling
effect and the engine co uld then over­
heat. Ask your authorized Aud i dealer for
assistance.
Tachometer (engine rev counter)
The tachometer indicates the engine RPM
(revolutions per minutes).
I f engine RPM drops below 1,500, you should
downshift to the next lower gear . T he red area
at the end of the scale indicates maximum
perm issible engine RPM after the break-in pe­
riod. Before reaching this area, move these­
lector lever to position 0/5 or ease your foot
off the accelerator pedal.
@) Note
The tachometer needle@c::> 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) ¢4' i n
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 stabilized .
This indicates that the MIL is working proper­
ly.
If the light does not go out after the engine
is started, or illuminates while you are driv­
i ng, a malfunction may exist in the eng ine sys­
tem . 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 cond ition corrected.
Contact your authorized Audi dealer.
If the light il luminates, the electronic speed
limiter may also be malfunct ioning. For more
information
c:> page 31 , Electronic speed
limiter.
An improperly closed fuel filler cap may also
cause the
MIL light to illuminate

On-Board Diagnostics
Fig . 18 Locat io n of Data Link Con nector (D LC)
On-Board Diagnostics monitors the compo ­
nents of your emission control system . Each
monitored component in your engine system
has been assigned a code. In case of a mal­
function, the component will be identified
and the fault stored as a code in the control
module memory.
The 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

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.
Catalytic converter
It is very important that your emission con­
trol system (catalytic conv ert er) is function ­
ing properly to ensure that your vehicle is run­
ning in on env ironm entally sound manner.
,,. Always use lead-free gaso line Q page 209,
Fuel supply .
,,. Never run the tank down a ll th e way to emp ­
ty.
,,. Never put too much moto r oil in your engine
Q page 219, "t':::r. Adding engine oil .
,,. Never try to push -or tow -start your ve hicle .
T he cata lytic converter is an eff ic ient "clean­
up" device built in to the exhaust system of
the vehicle . The catalytic converter burns
many of the polluta nts in the exhaust gas be ­
fore they are released into the atmosphe re . The exclus
ive use of unleaded f uel is critica lly
important for the life of the catalytic conv ert­
er and p roper funct ion ing of the eng ine .
A WARNING
=
-The temperature of the exhaust system
is high, both when driving and after stop­
p ing the eng ine .
- Never touch the exhaust tail pipes once
they have become hot. This could result
in burns.
- Do not park or operate the vehicle i n
areas where the hot exhaust system may
come in co ntact with dry grass, brush,
fue l spill or other material wh ich can
cause a fire .
- Do not app ly additional undercoating or
r u stp roofing on or nea r the exhaust
manifold, exhaust pipes, cataly tic con­
ver ter or he at s hields. Dur ing driv ing, the
substance used fo r undercoating could
overheat and cause a fire.
CI) Note
- Be aware tha t just o ne tank filling with
leaded fu el w ill alre ady ser io usly de ­
grade the performance of the cata lytic
converter .
- Do not exceed the cor rect engine oil level
Q poge 219.
-Do not drive until the fuel t ank becomes
comple tely empty . The engine cou ld mis ­
fire . Unburned fuel could also get into
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 mov ing.
- Do not contin ue to ope rate your veh icle
under these conditions, as otherwise fuel
can reach the catalyt ic converter. Th is
co uld result in overheating of the con­
verter, requir ing its replacement.
- To assure efficient operation of the Emis -
sion Control System: .,..

198 Driving and en vironm ent
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel .
.,. Shut the engine off when you are not dr iving
the vehicle.
.,. Do not warm up the vehicle by letting the
engine run at idle .
It makes sense to shut
off the engine in traffic
jams, when waiting for trains to pass at ra il­
road crossings, or at traff ic lights that have
l ong wa its on red . Turning the engine
off fo r
just 30-40 seconds saves more fue l than is
burned s tarti ng the eng ine again .
It takes a long time for the engine to warm up
fu lly when it is running at idle . Howeve r, wear
and nox ious em issions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and

Do not leave engine idling unattended af­
ter starting . If warning lights shou ld come
on to indicate improper operation, they
wou ld go unheeded. Extended idling also
produces heat, which cou ld 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 serviced at regular inter-
vals.
By having your vehicle regularly serviced by an
authorized Audi dealer he lps to ensure that it
runs properly and economically . The condition
of your vehicle not only affects its safety and
ab ility to hold its value, it also affects
fuel
consumpt ion .
Check you r oil ea ch time you fill you r tank.
The amount o f oi l used is re lated to engine
load and speed.
It i s normal fo r the oil consump tion of a new
engine to reach its lowest value after a certa in
mileage has been d riven.
You must drive your veh icle about 3,000 m iles
(S,000 kilometers) before you can properly
assess oil consumpt ion.

Fewer short trips
Fuel consumption will always be relatively
high on short trips .
.,. Try to avoid dr iv ing short distances w ith a
cold engine .
T he engine and cata lytic converter have to
reach their opt imal
operat ing temperature to
reduce fuel consumpt ion and nox ious emis­
s ions effectively .
Just after starting, a co ld eng ine in a mid-s ize
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 cl imbs to 12 mpg
(20 l/100 km) . After about
