HICL E OPER ATION------------------------
Functioning of Anti-Lock Brake
System (ABS)
The ABS contributes effectively to vehicle
control since it prevents the wheels from
locking when the brakes are applied. This
means that the vehicle remains steerable
and is less likely to skid.
Nota
Yo u don't have to "pump" the brake.
Just hold the brake pedal down.
However, do not expect that the ABS short­
ens braking distance under all circum­
stances. When driving on gravel or on newly
fallen snow on top of icy surfaces, braking
distance may be even longer , therefore, un­
der these circumstances, it is especially im­
portant that you drive slowly and with great
care.
202 How the
ABS system works
An automatic check is made when a speed
of about 4 mph (6 km/h) is reached.
When this happens a pumping noise can be
heard.
If an individual wheel begins to rotate too
slowly in relation to vehicle speed and tends
to lock, the ABS automatically reduces
brake pressure to prevent that wheel from
locking.
This automatic adjustment process
will cause a slight vibration of the
brake pedal and soma noises to alert
you that vehicle speed must be
adapted to existing road and traffic
conditions. Enhanced
ABS function {Offroad­
Mode)
To improve braking on loose terrain (for ex­
ample: gravel, scree, mud, slush, snow),
turn off the ESP (see page 205), which will
switch the ABS to a special mode designed
for off-road requirements.
In this mode, the ABS control system is
changed to allow a "wedge" of loose rock
or soil to form in the front of the wheels.
This improves braking performance.
The ESP indicator light in the instrument
cluster will come on when you have
switched to this special ABS mode (see
page 124).
This special ABS mode will remain active up
to about 40 mph (60 km/h). ABS operation
is not affected at speeds over 40 mph
(60 km/h).
To turn his special ABS mode off, press the
ESP button (To activate ESP, see page 152).
The ABS off-road mode will also be deacti­
vated when vou turn off the engine.

Engine
oil consumption
The rate of the oil consumption depends on
the quality and viscosity of oil, the speed at
which the engine is operated, the climate,
and road conditions as well as amount of
dilution and oxidation of the lubricant.
Because of these variables, no standard
rate of oil consumption can be established,
but drivers should expect higher oil con­
sumption at high speeds and when the en­
gine is new.
Therefore, we recommend that you check
the oil level at regular intervals (for example,
each time you are refuelling, or before going
on a long trip).
If the oil level should go below the minimal
level, the check engine oil level warn­
ing light* in the instrument cluster will
come on. See page 144. You should check
the oil level using the oil dip stick as soon as
possible, and then top off the oil as neces­
sary. Notes
• The engine in your vehicle de­
pends on oil to lubricate and cool all
of its moving parts. Therefore the
engine oil should be checked regu­
larly and kept at the required level.
• Lack of sufficient engine oil may
lead to severe engine damage.
• The oil pressure warning light is
not an oil level indicator.
A Always
heed all WAR NINGS
� on page 232.
Checking the engine oil level
The best time to check the engine oil level
is when the oil is warm.
To get a true reading, the vehicle must be on
level ground.
A Always heed all WAR NINGS
� on page 232.
• After turning off the engine, wait a few
minu tes for the oil to return to the oil pan. VE
HICLE CARE
• Pull out dipstick (arrow) and wipe it clean
with a rag.
• Reinsert dipstick; push it all the way in.
• Pull dipstick out again and read the level:
a - Yo u must not add oil.
b- You can add oil. The oil level may go
into the a range, but riot above the a
range
c - You must add oil.
After filling in oil, make sure that the oil
level is somewhere within the b range.
• After checking the oil level, please make
sure that the dipstick is pushed back in all
the way.

Adding engine oil
A Always heed all WA RNINGS
r!!J on page 232.
• Turn off the engine.
• Unscrew the oil cap from the cylinder
head cover.
• Add oil by a half quart (half liter) at a time.
• Check the oil level with the dipstick.
:236 The
oil level must never be above the
"a .. range.
Otherwise oil could be drawn into the crank­
case breather and get into the atmosphere
through the exhaust system. The oil
would bum then In the catalytic con­
verter and cause damage.
� WARNING
Spilled oil is a fire hazard. The oil
filler cap must be secure to avoid
an oil spill.
• Carefully screw the oil cap back on and in­
sert the oil dipstick all the way. Otherwise
oil could leak out when the engine is run­
ning. Changing
the engine oil
The engine oil must be changed according
to the intervals specified in your Mainte­
nance booklet.
This is very important because the lubricat­
ing properties of oil diminish gradually dur­
ing normal vehicle use.
Under some circumstances the engine oil
should be changed more frequently.
Change oil more often if you drive mostly
short distances, operate the vehicle in dusty
areas or under predominantly stop-and-go
traffic conditions, or have your vehicle
where temperatures remain below freezing
for exte nded periods.
Detergent additives in the oil will make
fresh oil look dark after the engine has been
running for a short time. This is normal and
is not a reason to change the oil more often
than recommended.

Engine cooling system
The cooling system is sealed and generally
requires little attention.
The cooling system has been filled at the
factory with a permanent coolant which
does not need to be changed. The coolant
consists of a mixture of water and the
man ufacturer's coolant additive G 12 ABD
-ant ifreeze on a glycol base with anti-corro­
sion additives (50% for USA models; 60o/o
for Canadian models). This mixture assures
the necessary frost protection and protects
alloy components in the engine's cooling
system from corrosion and scaling. It also
raises the boiling point of the coolant.
Do not reduce the concentration of the cool­
ant in the summer by adding plain water.
The proportion of coolant additive
must be at least 500fa but not more
than 600fa to maintain antifreeze protec­
tion and cooling efficiency.
238 For
year-r ound driving, antifreeze is added at
the factory for temperatures down to:
-31 °F (-35 °C) USA
-40 °F (-40 °C) Canada.
g Always heed all WA RNINGS
E!!1 on page 232.
Never use eny coolant additive
other than our G12 ABD additive
(check label) for your vehicle. This
coolant additive is available at au­
thorized Audi Dealers.
Other types of antifreeze can. above
all. significantly reduce corrosion
protection. The resulting corrosion
can cause a loss of coolant and
therefore serious engine damage. When
adding coolant additive to
your cooling system. please remem­
ber:
Under no circumstances may G12
ABD be mixed with other coolant ad­
ditives (for example G 11 ).
You can recognize G12 ABD in the
expansion tank by its red color. If
the liquid in the expansion tank is
brown, G 12 ABD has been mixed
with another coolant additive. In
this case. your vehicle's coolant
must be changed as soon as pos­
sible.
Note
Mixing coolant additives can result
in serious malfunction or engine
damage!

Checking the
engine coolant
level
The coolant expansion tank is located on the
left of the engine compartment -see il­
lustration.
The coolant level is automatically monitored
by the Auto-Check System -see page 141.
However, it is still recommended to check
the coolant lev�l visually from time to time
and always before going on a longer trip.
�W ARNING
To reduce the risk of being burned.
never open the hood if you see or
hear steam or coolant escaping
from the engine compartment.
Wait until no steam or coolant can
be seen or heard before carefully
opening the hood and following
the precautions on the next page.
Always heed all WA RNINGS
on page 232. To
obtain an accurate reading, the engine
must be switched off.
Since the expa nsion tank is transparent, the
cap need not be removed to check the cool­
ant level.
The coolant level must be between the
"MIN" and "MAX" marks when the en­
gine is cold and can be slig htly above the
"MAX" mark if the engine is warm. VE
HICLE CARE
The expansion tank in your vehicle is
equipped with an electric coolant level
checking device.
When the coolant level is too low, the warn­
ing light (see page 141) in the Auto-Check
System will blink until you add coolant and
the coolant level has been restored to nor­
mal.
Coolant losses
Coolant losses may indicate a leak in the
cooling system. In the event of coolant
losses, the cooling system should be in­
spected immediately by your authorized
Audi Dealer. It is not enough merely to add
coolant.
In a sealed system, losses can occur only if
the boiling point of the coolant is exceeded
as a result of overheating.

Brake fluid
The brake fluid reservo ir is located on the
left of the plenum chamber at the back of
the engine compartm ent.
242 Checking
brake fluid level
The correct fluid level is important for the
proper functioning of the brake system. The
fluid level in the brake fluid reservoir should
always be between the "MAX" and
"MIN" markings.
The fluid level may drop slightly after some
time due to the automatic adjustment of the
brake pads. This is no cause for alarm.
• If the brake fluid level falls con­
siderably below the "MIN"
mark, the brake warning light will
coma on. Do not continue to operate
the vehicle. The complete brake sys­
tem should be thoroughly checked
by an authorized Audi Dealer or
another qualified workshop and the
cause corrected.
The brake warning lamp lights up to indicate
a low fluid level in the reservoir.
For more details see "Warning I Ind icator
lights," page 126.
Contact an authorized Audi Dealer
immediately. Changing
brake fluid
The brake fluid reservoir can be dif­
ficult to reach, therefore, we recom­
mend that you have the brake fluid
changed by your authorized Audi
Dealer. Your dealer has the correct
tools and know-how to do this for
you.
Brake fluid absorbs moisture from the air. If
the water content in the brake fluid is too
high, corrosion in the brake system may re­
sult after a period of time. The boiling point
of the brake fluid will also decrease consid­
erably.

CARE-------------------------
Tires I Wheels
Tires are important but often abused parts
of a vehicle. They not only influence comfort
and ride, but perform vital safety functio �s.
This section is intended to provide you w1th
imp ortant information regarding their prop­
er use, care and replacement.
• Be sure to inspect your tires at least ev­
ery 2,000 miles (3 000 kilometres) for wear
and damage.
• Damage to wheels and tires is not always
easy to see. If you believe that a tire or
wheel has been damaged, it is best to have
it replaced as soon as possible. Internal tire
damage can never get better or ': heal" it­
self, it can only get worse over t1me. Tire
damage can lead to tire failure and loss of
vehicle control. See your authonzed Aud1
Dealer for advice and assistance.
• Mark tires before removing them. Re­
mount tires on the same vehicle side be­
cause the rotation direction must stay the
same.
252 •
Store removed tires in a cool, dry and pre­
ferably dark place. Tires which are not on
wheels should be stored standing up.
• New tires may have different tread
depths due to the configuration and des!gn
by the tire manufacturers. When replacing
tires, use ones with matching tread depth.
�W ARNING
• Tires age even if they are not be­
ing used. Tires which are more
than 6 years should be used only in
an emergency and then with cau­
tion.
• Avoid damaging tires and wheel
rims. If you must drive over a curb
or other obstacle, drive slowly and
as nearly as possible at a right
angle. Frequently check tires for
uneven wear and damage. M
WARNIN G continued
• Remove embedded material.
• Replace worn or damaged tires
immediately.
• Replace missing valve dust
caps.
• Keep oil, fuel, brake fluid, etc.
away from tires.
• Keep tires inflated correctly.
New tires
New tires tend to be slippery and cannot of­
ferfull traction until they have been properly
broken in.
�W ARNING
To help avoid loss of control, al­
ways operate a vehicle with new
tires at lower speeds and with spe­
cial caution for the first 300 miles
(480 kilometres).

Fuses
A problem in the electrical system may be
caused by a blown fuse.
Fuses are arranged in a centra lized unit. The
unit is located behind a cover at the end of
the dash board on the left hand side.
The crank handle for manual operation of
the electric sunroof* is cli pped on the inside
of the fuse box cover.
Two spare fuses are provided in the row of
fuses on the right.
It is a good idea to keep a supply of spare
fuses on hand. They are available from your
Audi Dealer.
274 Replacing
a fuse
� WARNING
A fuse with too high amperage
could damage the electrical part
and cause a fire. Do not use a fuse
with a higher amperage than the
fuse being replaced. ·
• To avoid damaging the electrical
system. turn off all lights and acces­
sories and remove the ignition key
before replacing a fuse.
• Open the cover of the centralized unit by
inserting a screwdriver in the slot of the
cover and pry it off.
• Check the fuse listing on the next pages
to find out which fuse belongs to the com­
ponent that has failed.
• Remove blown fuse with the plastic clip
prov ided. The clip is located on the holder in
the fuse box. •
Replace the blown fuse with a fuse of the
same amperage. You can recognize the
blown fuse by the burnt metal strip.
• Reinstall the fuse box cover.
Notes
• If a fuse blows repeatedly. do not
keep on replacing it. The cause of
the short circuit or overload must be
found. On no account should fuses
be repaired (e.g. patched up with tin
foil or wire) as this may cause seri­
ous damage elsewhere in the electri­
cal circuit or cause fire.

Lifting
vehicle
Lifting with workshop hoist
and with floor jack
Notes
• The vehicle should never be lifted
or jacked up from underneath the
engine oil pan, the transmission
housing, the front or rear axle or the
body side members. This could lead
to serious damage.
The same lifting points as illus trated on the
next page for the hoist also apply when a
floor jack is used.
e To avoid damage to the under­
body or chassis frame, it is neces­
sary to insert a rubber pad between
the floor jack and the lift points.
• To prevent damaging the shock
absorbers when lifting the vehicle
with a jack or on a hoist, the level
selection must be in the jack mode.
See next page. �W
ARNING
• To reduce the risk of serious in­
jury and vehicle damage, lift the
vehicle only at the special work­
shop hoist and floor jack lift points
illus trated. Failure to lift the ve­
hicle at these points could cause
the vehicle to tilt or fall from a lift
if there is a change in vehicle
weight distribution and balance.
This might happen, for example,
when heavy components such as
the engine block or transmission
are removed.
• When removing such heavy
components, anchor vehicle to
hoist or add correspo nding
weights to maintain the center of
gravity. Otherwise, the vehicle
might tilt or slip oH the hoist,
causing serious damage or person­
al injur y. DO-IT-YOU
RSELF SERVICE
�� WARNING continued
• If you must lift your vehicle with
a floor jack to work underneath,
be sure the vehicle is safely sup­
ported on stands intended for this
purpose.
• Before driving over a workshop
hoist, check that the vehicle weight
does not exceed the permissible lift­
ing capacity of the hoist.
• Before driving over a workshop
hoist, ensure that there is suHicient
clearance between the hoist and
low parts of the vehicle.
