WARNING continued
• If the brake warning light does
not go out with the engine running
and the parking brake released, or
lights up while you ere driving, the
fluid level in the brake fluid reser­
voir is too low.
• If you believe that it Is safe to do
so, proceed immediately at low
speed to the nearest authorized
Audi Dealer or qualified workshop
and have the brake system in­
spected.
• Please be very careful and be
sure to remember that after sev­
eral brake applications, you will
need greater pressure on the brake
pedal to stop your vehicle. Conse­
quently, you must allow for in­
creased braking distances. Trying
to brake as quickly as usual could
lead to an accident.

CONT
ROLS AND EQUIPMENT---------------------
�W ARNING
• The engine compartment of any
motor vehicle is a potentially haz­
ardous area. Before you check any­
thing in the engine compartment,
stop the engine and let it cool
down. Always exercise extreme
caution when working under the
engine hood. Heed all of the
WA RNINGS on page 232.
• To reduce the risk of being
burned, never open the hood if you
see or hear steam or coolant es­
caping from the engine compart­
ment. Wait until no steam or cool­
ant can be seen or heard before
carefully opening the hood.
• Never touch the radiator fan.
The auxiliary fan is temperature
controlled and can switch on sud­
denly.

WARNING continued
• Reduce the risk of scalding from
hot coolant by following these
steps:
If the coolant reservoir cap must
be removed. wait until the en­
gine has cooled down.
- Protect face, hands. and arms
from escaping fluid and steam
by cov ering the cap with a large.
thick rag.
Tu rn the cap slowly and very
carefully in a counter-clockwise
direction while applying light.
downward pressure on the top
of the cap.
- To help avoid being burned. do
not spill antifreeze or coolant on
the exhaust system or hot en­
gine parts. Under some condi·
tions. the ethylene glycol in en·
gine coolant can catch fire. •
If a visual check shows the coolant level
and the V-belt normal, and the warning light
still does not go out, do not continue
driving. See your authorized Audi Dealer.
• If the coolant level and the V-belt are nor­
mal, the malfunc tion may be in the auxiliary
radiator fan. You can continue driving to the
nearest authorized Audi Dealer. The wind
from the moving vehicle and the main radia­
tor fan driven by the V-belt will be enough to
keep the angine cool. However, avoid idling
for a long time or driving very slowly.
If the V-belt is torn, the main radiator fan, the
power steering and the gener ator will also
not work.
Obtain expert assistance.
Refer to "Coolant temperature gauge" on
page 118 for detai ls.

possibly causing personal injury
from the moving wiper linkage.
• Do not wash. wax or dry the en�

WARNING continued
e Do not clean the underside of
the chassis, fenders. wheel cov­
ers. or other hard to reach parts
without protecting your hands and
arms. You may cut yourself on
sharp-edged metal parts.
• Moisture and ice on brakes may
affect braking efficiency. Test the
brakes carefully after each vehicle
wash.
The engine compartment and transmission
have been corrosion protected at the facto­
ry.
Remove leaves from the plenum panel in
front of the windshield under the engine
hood. This prevents the water drain holes
from becoming blocked, and it prevents de­
bris from entering the vehicle interior
throug h the heating and ventilation ducts. Good
anti-corrosion treatment is very im­
porta nt, particularly in the winter. If the ve­
hicle is frequently driven on salted roads,
the entire engine compartment and plenum
panel should be thor oughly cleaned at the
end of winter and retreated to prevent salt
damage. At the same time, the underside of
the vehicle should be washed as well.

Never touch the radiator fan. The
auxiliary electric fan can switch on

sary to work underneath the ve­
hicle. The jack supplied with the
vehicle is not adequate for this
purpose and could collapse caus­
ing serious personal injury.

Engine compartment
�W ARNING
To help avoid injury, before you
check anything under the hood:
• Switch off the engine. Remove
the ignition key.
• Set the parking brake fully.
Move the selector lever toP (Park).
• Always let the engine cool
down. Hot components will burn
skin on contact.
• Never spill fluids on hot engine
components. They can cause a
fire.
• Never touch the radiator fan.
The auxiliary electric fan can
switch on suddenly and injure you.

WARNING continued
• If work on the fuel system or the
electrical system is necessary:
- Always disconnect the battery.
Never smoke or work near heat­
ers or open flames. Fluids in the
engine compartment could start
a fire.
Keep an approved fire extin­
guisher 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. M
WARNING continued
• If you must perform a check or
repair with the engine running:
First, fully apply the parking
brake, move selector lever to
P (Park).
Always use extreme caution to
prevent clothing, jewelry, or
long hair from getting caught in
the radiator fan, V-belts or other
moving parts, or from contact­
ing hot parts. Tie back hair be­
fore starting, and wear no cloth­
ing that will hang or droop into
the engine.

Radiator
fan
The radiator fan is driven by the engine via
the V-belt. The viscous clutch regulates the
speed of the fan according to the tempera­
ture of the coolant.
An auxiliary electric radiator fan switches on
and off depending on coolant temperature
and other vehicle operation conditions.
� WARNING
• Always use extreme caution to
prevent clothing. jewelry, or long
hair from getting caught in the en­
gine driven radiator fan, V-belt or
other moving parts.
• Never touch the auxiliary elec­
tric radiator fan. The fan can
switch on suddenly and injure you.
Always heed all WA RNINGS
on page 232. Power
steering
Yo ur vehicle is equipped with a Servotro­
nic power steering. The degree of
power assistance is regulated electronically
according to road speed.
The fluid reservoir is in the engine compart­
ment near the windshield washer container.
The correct fluid level in the reserv oir is im­
portant for the proper functioning of power
steer ing.
The power steering fluid level is checked
during the scheduled Maintenance ser­
vices.
If the electronic regulating system is not
working properly, this is most noticeable
when turning the steering wheel at low
speeds (for example when parking) -more
effort will be required than usual. The fault
should be rectified by an Audi Dealer as
soon as possible. VEH
ICLE CARE
Note
• When the engine is running, never hold
the steering wheel turned all the way to the
right or to the left for longer than 15 sec­
onds. The power steering pump will over­
heat the hydraulic fluid if you hold the steer­
ing wheel all the way turned.
This will damage the power steering
system.
Each time the steering wheel is turned all
the way to the right or left when stopped,
you will hear noises caused by the severe
stress placed on the power steering pump.
At the same time, engine idle speed drops.
• If the power steering system
should fail, or if the engine is not
running (for example, while being
towed). you will still be able to steer
the vehicle, however. more effort
will be required.
• If the power steering system should
have a leak, or is not functioning properly,
contact your authorized Audi Dealer imme­
diately.

Spark plugs
Spark plugs are replaced during the Audi
scheduled Maintenance Service.
If you have to replace the spark plugs be­
tween the Audi Maintenance services, be
sure to note the following:
• Engine, spark plugs and the ignition sys­
tem are matched to each other. To avoid
faulty operation or engine damage, use only
Original Audi spark plugs. It is especially im­
portant to note the number of electrodes on
the spark plug and the heat value.
• Since spark plug specifications may
change for technical reasons during a model
year, we recommend that you obtain your
spark plugs from an authorized Audi Dealer,
who has the latest information.
Always heed all WARNINGS
on page 232. Belts
Ribbed V-Belt
The radiator fan, hydraulic pump (power
steering), alternator and air conditioner
compressor are driven by one V-belt.
The installed V-belt conforms to the highest
quality requirements. The V-belt adjusts its
own tension.
Replacing of the V-belt should be
performed by your authorized Audi
Dealer or a qualified workshop.
When replacing a belt, it is not sufficient to
use just any belt of the same size. For safe
and reliable operation, use only Genuine
Audi V-belts specially designed for your ve­
hicle. The correct belts can be obta ined at
your authorized Audi Dealer. �W
