Instrument s and warning /indicator lights 11
Warning light in the instrument cluster
display
If the. warning light in the instrument clus ­
ter disp lay flashes, this can mean one of two
things: either the coolant
t empera ture is too
high, or the coolant
level is too low
¢ page 31.
If the needle is well in the upper area of the
gauge, the coolant temperature is too high.
Stop the vehicle, switch the engine off, and
allow it to cool.
If the warni ng light comes on
again after driving a short distance, contact
an author ized Audi dealer or other qualif ied
workshop.
_& WARNING
- Always observe the warning in
¢ page 230, 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 e ngine coolant .
CD Note
-Mounting additional lights or accessories
in front of the a ir inlets reduces the cool­
ing effect of the rad iator. At high 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 co uld then over­
heat. Ask you r aut horized Aud i dealer for
assistance.
Tachometer (engine rev counter )
The tachometer indicates the engine RPM
(revolutions per minutes).
If engine RPM drops be low 1,500, you should
downshift to the next lower gear . Th e red area at
the end of the scale indicates maximum
perm issible eng ine RPM after the break-in pe­
riod. Before reaching this area, move these­
lector lever to position
D (Drive) or ease your
foot off the accelerator pedal.
CD Note
The tachometer needle @ ¢ page 10,
fig. 3
should on ly briefly be in the red
zone: you cou ld damage your eng ine! The
beginn ing of the red zone var ies depend-
i ng on the engine.
@) For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise .

A WARNING
- USA models: If the 1111 warning l ight
and
the m warning light come on to ­
gether, the rear wheels could lock up
first under hard braking . Rear wheel lock ­
up can cause loss of vehicle control and
an acc ident. Have your vehicle repaired
immediately by your authorized Audi
dealer or a qualified workshop . Dr ive
slowly and avoid sudden, hard brake ap·
plicat ions.
- Canada models: If the brake warn ing
light . and the ABS warning light
II]
come on together, the rear wheels could
.
lock up first under hard braking . Rear
wheel lock-up can cause loss of vehicle
control and an accident . Have your vehi­
cle repaired immed iately by your author·
ized Audi dealer or a qualified workshop .
Drive s low ly and avoid sudden, hard
brake applications.
- If the brake warning/ind icator light does
not go ou t after a few seconds and the
pa rking brake released, or lights up wh ile
you are driv ing, the fluid level in the
brake fluid reservoir is too low. If yo u be ­
lieve that it is safe to do so, proceed im­
mediately at low speed to the nearest
author ized Audi dealer or qualif ied repair
facility and have the brake system in·
spected.
- Always keep in mind that after severa l
brake applications, you will need greater
pressure on the brake pedal to stop your
veh icle. Do not rely on strained brakes to
respond with max imum stopping power
in critical s ituations. You must allow fo r
increased braking dis tances. The extra
distance used up by fading brakes could
lead to an accident.

the engine starts and the idle has stabilized. T
his 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 dr iv­
ing, a malfunction may exist in the engine 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 condition corrected.
Contact your authorized Audi dealer .
If the light illum ina tes, the electronic speed
limiter may also be mal functioning. For more
