The amount of oil used is related to engine
load and speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a cer­
tain mileage has been driven.
You must drive your vehicle about 3,000
miles (5 000 kilome tres) before you can
properly assess oil consumption.
This also applies to fuel consumption and
engine output.

mates may not correspond to your
actual consumption on the road.
which will vary depending upon ve­
hicle load and speed. road and
weather conditions. trip length. etc. The
catalytic converter is an efficient
"clean-up" device built into the exhaust
system of the vehicle. The catalyttc convert­
er burns many of the pollutants in the ex­
haust gas before they are released into the
atmosphere.
The exclusive use of unleaded fuel is
critically important fo.r the life of
the catalytic converter and proper
functioning of the engine - see
page 225.
The catalytic converter will be per­
manently damaged by:
• Exc eeding the correct engine oil
level - see page 236;
• Driving until the fuel tank be­
comes completely empty. The en­
gine could misfire. Unburned fuel
could also get into the exhaust sys­
tem and this could cause the catalyt­
ic converter to overheat;

Braking
General notes
• The brakes on today's automobiles are
still subject to wear, depending largely on
operating conditions and driving habits. On
vehicles which are driven mostly in stop­
an d-go city traffic or which are driven hard,
the brake pads should be checked by your
authorized Audi Dealer more often than
specified in the Maintenance booklet.
• On steep slopes, you should use the
braking effect of the engine. This way, you
prevent unnecessary wear to the brake sys­
tem. If you must use your brakes, do not
hold the brakes down continu ously. Pump
the brakes at interv als.
• Under certain conditions, for example,
when driving through water or very heavy
rain, or even after washing your vehicle, the
braking effect can be reduced due to the
wet brake pads or pads which are iced-up in
the winter. A few cautious brake applica­
tions should dry off the brake pads or re­
move ice coati ngs. The
effect iveness of the brakes can be re­
duced when the vehicle is driven on a salt­
covered road and the brakes are not used.
Clean off accumulated salt coating from
brake discs and pads with a few cautious
brake applications.
�W ARNING
• If you damage the front spoiler,
or if you install a different spoiler,
be sure the air flow to the front
brakes is not obstructed, other­
wise the brake system could over­
heat reducing the effectiveness of
the entire brake aystem.
• Failure of one brake circuit will
impair the braking capability re­
sulting in an increased stopping
distance.
Avo id driving the vehicle and have
it towed to the nearest authorized
Audi Dealer or qualified work­
shop. VEH
ICLE OPERATION
Brake booster
�W ARNING
• The brake booster works with
vacuum pressure which is created
only when the engine is running.
Never let the vehicle roll to a stop
with the angina shut off.
• If the brake booster is not work­
ing, for example when towing your
vehicle, or because the brake boo­
ster has somehow been damaged,
the brake pedal must be pressed
harder to make up for the lack of
booster assistance.

VE
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.

RE----------------------------------------------------
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.
