,&_ WARNING
- Always observe the warning in
¢ page 213, 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 engin e RPM
(r evolutions 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 a rea, 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.

not an indicator for a low engine oil lev­
el. Do not rely on it. Instead, check the
oil level in your engine at regular inter­
vals, preferably each time you refuel,
and always before going on a long trip.
- The yellow oil level warning indication
l!I requires oil refill or workshop serv­
ice without delay. Do not wait until the

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
ing, 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 illuminates, 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

If the engine should not start immediately,
the starting process is automatically stopped
after a short time. Repeat starting procedure .
When starting the engine , major electrical
loads are switched off temporari ly.
After a cold engine is started, there may be a
brief period of inc reased noise because oil
pressure must first build up in the hydraulic
valve adjusters. This is norma l and not a cause
for concern.
A WARNING
- Never allow the engine to run in confined
spaces - danger of asphyxiation.
- Never turn off the engine until the vehi­
cle has come to a complete stop.
- Always take the key with you whenever
you leave your vehicle. Otherwise, the
engine could be started or electrical
equipment such as the power windows
could be operated . This can lead to seri­
ous injury .
- Never leave children or persons requiring
assistance unattended in the vehicle. The
doors can be locked using the remote
transmitter, preventing people from es­
caping from the vehicle on their own in
the event of an emergency. Depending
on the time of year, peop le inside the ve­
hicle can be exposed to very high or very
low temperatures .
CD Note
-Avo id high engine rpm, full throttle and
heavy engine loads until the engine has
reached operating temperature - other­
wise you risk engine damage.
@ For the sake of the environment
Do not let the engine run while parked to
warm up. Begin driving immediately. This
reduces unnecessary emissions.

overheat, premature wear and increased
stopp ing distance.
- Under certain climatic and operating
condit ions such as passing through wa­
ter, driving in heavy ra in or after wash ing
the vehicle, the effect iveness of the
brakes can be reduced . In winter, ice can
accumulate on the brake pads, linings,
discs and drums. Carefully apply brakes

ings will be cleaned off after a few ca re ­
ful brake applications.
- Driv ing for an extended pe riod of time on
salt -covered roads without using you r
brakes can also affect braking efficiency.
Clean off accumulated salt coating from
brake discs and pads w ith a few careful
brake applicat ions.
- If you damage the front spoiler, or if you
install a different spoiler, be sure the air
flow to the front brakes is not obstruct­
ed . O therwise the brake system could
overheat reducing the effectiveness of
the ent ire brake system.
- Failure of one brake c ircuit will impair
the braking capability resulting in an in­ creased stopp ing distance. Avoid driv ing
the vehicle and have it towed to t he near­
est author ized Audi dealer or qualif ied
workshop.
- Never let the vehicle roll to a stop w ith
the engine shut off.
- If the brake booster is not working, for
example when towing your ve hicle, or
because the b rake booste r has somehow
been damaged, the brake pedal must be
pressed considerab ly harder to make up
for the lack of booster assistance.
