Warning light in the instrument cluster display-1-
If the _L warning light in the i nstrument clus ter display flashes, this
can mean one of two things: either the coo lant
temperature is too
high, or the coolant
level is too low ~ page 34 .
If the needle is well in the uppe r area of the gauge, the coo lant
temperature is too high.
Stop the vehicle, switch the engine off, and
allow it to cool.
If th e war ning light comes o n ag ain af ter driv ing a
short distance, contact an author ized Aud i dea ler or othe r qualified
wor ksh o p.

• Alway s observe the warn ing in :::} page 267, "Engine compart·
ment ", before opening the hood and checking the engine coolant
level.
• Never open the engine hood if you see or hear steam, or if you
s ee engin e 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 .
0 Note
• Mounting add ition al lights o r accesso ries in fron t of the a ir inlets
reduces the cooling effect of the radiator . At high outside tempera ­
tur es o r high engine load, the eng ine could ove rhe at.
• The front spo iler has been designed to properly d istribute the
c oo lin g air when the vehicle is moving. If the sp oi ler is d amaged, this

to have the malfunction corrected.
If the ABS system malfunctions, the ABS warning/indicator light illu­
minates together with the brake system malfunction warning/indi­
cator light~ & .
& WARNING
• Always observe the warnings in~ page 267, "Engine compart­
ment", before opening the hood and checking the brake fluid.
• Driving with low brake fluid is a safety hazard. Stop the car and
get professional assistance.
• USA models: If the BRAKE warning light and the ' warning
light 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 vehicle repaired immediately by your
authorized Audi dealer or a qualified workshop. Drive slowly and
avoid sudden, hard brake applications.
• Canada models: If the brake warning light (Q)} and the ABS
warning light come on together, the rear wheels could lock up
& WARNING (continued)
first under hard braking. Rear wheel lock-up can cause loss of
vehicle control and an accident. Have your vehicle repaired imme­

• Before reaching into the front plenum panel, always remove
the ignition key. Otherwise, the windshield wiper system could
unintentionally be switched on, possibly causing personal injury
from the moving wiper linkage.
• Never reach into the area around or touch the radiator fan. The
auxiliary fan is temperature controlled and can switch on suddenly
- even when the ignition is off.
• Do not wash, wax or dry the engine with the engine running.
Moving or hot parts could injure you .
• Do not clean the under side of the chassis, fenders, wheel

Checking and filling Ill
-------------~--
Closing the engine hood
- Pull the hood down until the pressure from the struts is
reduced.
- Let the hood
drop down and latch in place. Do not try to
push it shut;
it may fail to engage=:> &.
& WARNING
A hood that is not completely latched could fly up and block your
view while driving.
• When you close the engine hood, check it to make sure the
safety catch has properly engaged. The hood should be flush with
the surrounding vehicle body parts.
• If you notice while driving that the hood is not secured prop­
erly, stop at once and close it. •
Working in the engine compartment
Be especially careful whenever you work in the engine
compartment.
Whenever you must perform any work in the engine compartment,
for example checking and filling different fluids, there is a risk of injury, burns and accidents. To prevent personal injury always
observe the following WARNINGS. The engine compartment of any
vehicle is a hazardous area=>& .
& WARNING
To help avoid injury, before you check anything under the hood:
• Turn off the engine.
• Remove the ignition key.
• Apply the parking brake.
Safety first
& WARNING (continued)
• Move selector lever of automatic transmission to "P" (Park);
put manual transmission in Neutral.
• Always let the engine cool down. Hot components will burn
skin on contact.
• To reduce the risk of being burned, never open the hood if you
see or hear steam or coolant escaping from the engine compart­
ment. Wait until no steam or coolant can be seen or heard before
carefully opening the hood.
• Keep children away from the engine compartment.
• Never spill fluids on hot engine components. They can cause a
fire.
• Never touch the radiator fan. The auxiliary electric fan is
temperature controlled and can switch on suddenly.
• Never open the coolant reservoir cap when the engine is still
warm. The coolant system is pressurized and hot coolant could
spray out.
• Protect your face, hands and arm from steam or hot engine
coolant by placing a thick rag over the cap when you open the
coolant reservoir.
• If work on the fuel system or the electrical system is necessary:
-Always disconnect the battery.
- Never smoke or work near heaters or open flames. Fluids in
the engine compartment could start a fire.
- Keep an approved fire extinguisher immediately available.
• To avoid electrical shock and personal injury while the engine is
running or being started, never touch:
-Ignition cables
- Other components of the high voltage electronic ignition
system.
• If you must perform a check or repair with the engine running: ..,
