transport fue l to use for yo ur lawn mowe r,
snow blower, etc., be very careful and al­
ways observe local and state laws regard­
ing the use, transportat ion and storage of
such fuel containers . Make certain the con­
t ainer meets industry standards (ANSI/
AS TM F 852 -86).
(D Note
Never drive yo ur vehicle unt il the fuel tank
is completely empty . The irregular supp ly
of fuel can cause misfi ring. Gasoline could
enter the exhaust system and damage the
catalyt ic converte r.

Refueling procedure
• Insert the fuel nozzle from the gasoline
pump into the fuel fi ller neck as far as it wi ll
go .
• Select a medium refueling rate so that the
no zz le switches off automatically when the
tank i s full .
Putting th e fuel cap bac k on
• After filling your tank, twist the fuel cap
clockw ise as far as it will go .
• Close the fue l filler flap.
T o avoid fuel spill ing or evaporating from the
fuel tank always close fuel cap properly and
completely . An improper ly closed fuel filler
cap may also cause the MIL lamp ¢
page 26
to come on.
A WARNING
Improper refue ling or handling of fuel can
cause fire, explosion and severe burns.
- Fuel is highly flammable and can cause
severe burns and other injur ies .
- Failure to shut the engine off while refu­
eling and/or to insert the pump nozzle
fully into the fuel filler neck could cause
fue l to spray out of filler neck or to over­
flow. Fue l spray and overflowing fuel can
cause a fire .
- Never use a ce llu lar telephone while re­
fue ling. The electromagnet ic rad iation
can cause sparks that can ignite f uel va­
pors and cause a fire.
- Never get back into yo ur vehicle while re­
fuel ing.
If in excep tional circumstances
you must get back in your vehicle while refueling, make certain that you close
the door and touch metal to discharge static electricity before touching the fill­
er nozzle again . Static electr icity can
cause sparks that can ignite fuel vapors
released during refueling.
- Never smoke or have an open f lame any­
where in or near your veh icle when refu ­
eling or filling a portab le fuel conta iner .
- For your safety, we strongly recommend
that you do not t ravel with a portable

1 78 Fuel supply and filling your fuel tank
fuel container in your vehicle. The con­
tainer, full or empty may leak and could
cause a fire, especially in a crash.
- If, under exceptional circumstances, you
must transport a portable fuel container,
please observe the following:
- Never fill a portable fuel container
while it is anywhere in or on the vehicle
(for example, in the luggage compart­
ment, or on the trunk). Static electrici­
ty can build up while filling and can ig­ nite fuel vapors causing a fire .
- Always place a portable fuel container
on the ground before filling.
- Always keep the filler nozzle complete­
ly inside the portable container before
and during filling.
- If filling a portable container made of
metal, the filler nozzle must always be in contact with the container. This will
help prevent static electricity from dis­
charging and cause a fire.
- Never spill fuel inside the vehicle or
luggage compartment. Fuel vapors are
highly flammable.
- Always observe local and state/provin­
cial laws regarding the use, storage
and transportation of fuel containers .
- Make certain the fuel container meets
industry standards (ANSI/ ASTM
F8S2 -86) .
d) Note
If any fuel has spilled onto the car, it
should be removed immediately to prevent
damage to the paint .
@ For the sake of the environment
As soon as the correctly operated nozzle
switches off automatically for the first
time, the tank is full. Do not try to add more fuel because fuel may spill out. In
addition, the expansion space in the fuel
tank will be filled -causing the fuel to
overflow when it becomes warm and pol­
lute the environment.
(D Tips
- Running your engine while refueling may
cause vapors to escape or even cause
fuel to spill out of the tank. This would
then shut off the fuel nozzle before the
tank is full .
- Do not refuel your vehicle with the igni­
tion turned on. The fuel gauge may oth­ erwise not indicate the correct fuel level
after refueling .
- The fuel filler flap of your vehicle is not
locked when you lock the vehicle from
the inside .
Unlocking the fuel filler flap
by hand
You can open the fuel filler flap by hand if the
power locking system should fail.

level should be between the "MIN" and
"MAX" markings. When the engine is warm,
the level may be slightly above the "MAX"
marking .
The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration
<=> page 181.
To obtain an accurate reading , the engine
must be switched
off.
The expansion tank in your vehicle is equipped
with an electric coolant level sensor.
When the coolant level is too low, the warning
light in the Auto-Check System <=>
page 14 will
blink until you add coolant and the level has
been restored to normal. Even though there is
an electric coolant level sensor, we still rec­
ommend you check the coolant level from
time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling
system. In the event of coolant loss, the cool­
ing system should be inspected 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.
A WARNING
The cooling system is under pressure and
can get very hot. Reduce the risk of scald­
ing from hot coolant by following these
steps.
- Turn
off the engine and allow it to cool
down.
- Protect your face, hands and arms from escaping fluid and steam by covering the
cap with a large, thick rag .
- Turn the cap slowly and very carefully in
a counter-clockwise direction while ap­
plying light, downward pressure on the
top of the cap .
- To avoid being burned, do not spill anti­
freeze or coolant on the exhaust system

or hot engine parts. Under certain condi­
tions, the ethylene glycol in engine cool­
ant can catch fire.
([) Note
Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant. Add- ing radiator repair fluid may adversely af­
fect the function and performance of your
cooling system and could result in damage
not covered by your New Vehicle limited
Warranty .
Adding coolant
Be very careful when adding engine coolant.
Before you check anything in the engine com­
partment ,
always read and heed all WARN­

We recommend using only coolant additive
G12 ++, G13 or in an emergency G12 +. Do
not
use a different additive. In an emergency use
plain water until you can get the correct addi­
tive and can restore the correct ratio. This
should be done as soon as possible.
If you have lost a considerable amount of
coolant , then you should add cold antifreeze
and cold water only when the engine is cold.
Always use
new engine coolant when refilling . .,.

188 Checking and filling
Do not fill coolant above the "MAX" mark. Ex­
cess coolant will be forced out through the pressure re lief valve in the cap when the en ­
g ine becomes hot.
A WARNING
- The coo ling system is under pressure and
can get very hot. Reduce the risk of
scalding from hot coolant by following
these steps.
- Turn
off the eng ine and a llow it to cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering
the cap with a large, thick rag.
- Turn the cap slowly and very ca refully
i n a co unte r-clockwise d irection while
apply ing light, downward press ure on
the top of the cap.
- To avoid being burned, do not spi ll an ­
tifreeze or coolant on the exhaust sys­
tem or hot engine parts. Under certa in
conditions, the ethylene glyco l in en­
g ine coolant can ca tch f ire.
- Antifreeze is poisonous. Always store an­
t ifreeze in its original container and we ll
o ut of the reac h of children.
- If you drain the coolant, it must be
caught and safely stored in a p roper con­
ta iner clear ly ma rked "poison".
(D Note
- Do not add coolant if the expansion tan k
i s empty. A ir could enter the cooling sys­
tem and damage the eng ine. If this is
the case, do not continue driving. Seek
professional assistance.
- Coolant po llutes the e nv ironment and
could cause an engine fire. Excess coo l­
ant will be forced ou t through the pres ­
su re re lief v alve in the ca p when the en­
gine becomes hot .
- If, in an emergen cy, only water can be
added, the corre ct ratio be twee n wa te r
and antifr eeze¢
page 186 must be re ­
stored as soon as possib le .

Radiator fan
The radiator fan switches on automatically by
itself
T he rad iator fan is driven by the engine v ia the
V-belt. The viscous clutch regulates the spee d
of the fan acco rding to the temperature of the
coolant.
An a uxiliary electric radiator fan* sw itches on
and

ING S c:> .&.. in Working in the engine compart­
ment on page 179 .
~ Read the brake fluid level from the brake
fluid reservoir
c:> fig. 149, <=> page 181,
fig . 145.
The brake flu id level must be be­
tween the "MIN" and "MAX" markings.
The brake fluid reservoir is located at the rear
partition of the engine compartment on the
left side <::;>
page 181 .
The fluid level may drop slightly after some
time due to the automatic adjustment of the
brake pads . This is not cause for alarm .
If the brake fluid level falls
considerably be­
low the "MIN" mark, the brake warning/indi­
cator light (USA models: ., Canada models:
• will come on
<::;> page 13. Do not continue
to operate the vehicle . The complete brake
system should be thorough ly checked by an
author ized Audi dealer or qua lified workshop
and the cause corrected.
If the brake fluid lev­
e l is too low, the brake warning/indicator ligh t
will illuminate . Contact an authorized A ud i
dealer
immediately.
@ Tips
The brake f luid reservoir is located under­
neath the cover .
Checking and fillin g 189
Changing brake fluid
Have the brake fluid changed by on experi­
enced technician.
Brake fluid absorbs moisture from the air. If
the water content in the brake fluid is too
high, corrosion in the brake system may result
after a period of time . The boiling point of the
brake flu id will also dec rease considerably and
decrease braking pe rformance.
Therefore, the brake fluid must be changed
ev ery two years. Always use new brake flu id
which conforms to Federal Motor Vehicle
Standard "F MVSS 116 DOT 4".
The brake fluid reservo ir can be d iff icult to
reach, the refore, we recommend that you
have the brake fluid changed by your author­
i zed
Audi d ealer. Your dealer has t he correct
tools, the right brake fl uid and t he know-how
to do this for you .
A WARNING -.
-Brake fluid is poisonous . It must be stor­
ed only in the closed original container
out of the reach of children!
- Brake failure can resu lt from o ld or inap­
propriate brake f luid. Observe these pre­
cautions:
- Use only brake fluid that meets SAE
spe cificat ion
J 1 7 03 and conforms to
Federa l Moto r Ve hicl e Standard 116.
Always check with yo ur authorized Audi
dealer to make sure yo u are using the
correct bra ke fluid. The correct type of
brake f luid is also indicated on the
brake f luid reservoir.
- The brake fluid must be new. Heavy use
of the brakes can cause a vapor lock if
the brake fluid is left in the system too
l ong . This can seriously affect the effi­
c iency of the brakes as well as your
safety. This cou ld resu lt in an accident.
(D Note
Brake fluid will damage the paint of your
vehicle .

of driving you p lan to do .
Neve r e xcee d the m ax imum inflati on pres­
s u re list e d on th e tir e s ide wall f or a ny r ea­
s on.
Remember that the vehicle manufacturer, not
the tire manufacturer , determ ines the co rrect
tire pressure for the t ires on your veh icle .
It is important to check the tire pressure when
the tires a re cold .
- Read the required t ire pres sure from the tire
pressure label. The ti re pressure label is lo­
cated on the driver's side 8-p illar . The t ire
pressure label lists the recommended cold
t ire inflat ion p ressu res for the veh icle at its
maximum capacity we ight and the tires that
were on you r vehicle at the time it was man­
ufactured . For recommended tire pressures
for normal load condit ions, please see chap­
ter
9 page 199.
-Turn the valve stem cap counter-clockwise
to remove it from the tire valve.
- Place the a ir pressure gauge on the valve.
- T he tire pressures should on ly be checked
and adjusted when the tires are cold. The
s li ghtly raised pressures of warm tires must
not be reduced.
- Adjust the tire pressure to the load you are
carrying .
- Reinsta ll the va lve stem cap on the valve.
When should I check the tire pressur e?
The correct tire pressure is especially impor­
tant at high speeds. The pressure should
therefore be checked at least once a month
and always befo re starting a journey. Do not
forget to check the tire pressure for the spare wheel.
When should I ad ju st th e tire p re ss ures?
Adj ust the tire p ressure to the load you are
carry ing . After chang ing a wheel
or replacing
wheels you have to adjust the tire pressures
on all wheels . In addition, you must then in iti­
alize the new tire pressures in th e tire pres­
sure monito ring system*
c> page 213.
A WARNING
Incorrect tire pressures and/or underinfla­
tion can lead sudden tire fa ilure, loss of
control, collision, serious personal injury
or even death.
- When the
Rt] warning symbol appears in
the instrument cluster, stop and inspect
the t ires.
- Incorrect tire pressure and/or underinfla­
tion can cause increased tire wear and
can affect the hand ling of the vehicle and
stopping abi lity.
- I nco rrect tire pressures and/or underin­
f lation can also lead to sudden t ire fail­
ure, including a blowout and sudden de­
flation, ca using loss of vehicle contro l.
- The driver is responsible for the co rrect
tire pressures for all tires on the veh icle.
The applicable pressure values are locat ­
ed on a sticker on the driver's side B -pil­
lar.
- Only when all tires on the vehicle are fil­
led to the correct pressure, the tire pres­
sure monitoring system * can work cor­
rectly.
- The use of incorrect tire pressure va lues
can lead to acc idents or other damage.
Therefore it is essential that the driver
observe the spec ified t ire pressure values
for the tires and the correct pressures for
the function of the t i re pressure monitor­
ing system*.
- Always inflate t ires to the recommended
and correct t ire p ressure before dr iving
off.
- Driving with underinf lated tires bend
mo re, letting them get too hot resulting
in tread sepa ration, s udden tire failure
and loss of cont ro l.
- E xcessive speed and/overloadi ng can
cause heat b uild- up, sudden tire failure
and loss of cont ro l.
- I f the tire pressure is too low or too high,
the t ires will wear prema turely and the
vehicle wi ll not handle well. ..,

-All four wheels must be fitted with radia l
t ires of the same type, size (roll ing cir­
cumference) and the same tread pattern .
Driv ing with different tires reduces veh i­
cle handling and can lead to a loss of
control.
- If the spare tire is not the same as the
t ir es that are mounted on the veh icle -
for example with winte r tires -o nl y use
the spare tire for a short period of time and dr ive wi th extra care. Refit the nor­
ma l road whee l as soon as safely possi ­
ble.
- Never drive faster than the maxim um
speed for which the tires on your vehicle
are rated because tires that are driven
faster than their rated speed can fail
sudden ly.
- Overloading tires cause heat build- up,
sudden tire failure, including a blowout
and sudden deflation and loss of control.
- Temperature grades app ly to tires that
are properly inflated and not over or un­
der inflated .
- For technical reasons it is not a lways
poss ible to use wheels from other
vehicles -in some cases not even wheels
from the same vehicle model.
- If you install wheel tr im discs on the ve­
hicle wheels, make sure that the air flow
to the brakes is not blocked. Reduced air­
flow to the brakes can them to overheat,
increasing stopping distances and ca us­
ing a collision.
- Run flat t ires may on ly be used on
vehicles that we re equ ipped w ith them
at the facto ry. The vehicle must have a
chassis des igned for run flat t ires and a
facto ry-installed tire p ress ure monito r­
ing system* that indicates a loss of tire
pressure. Incorrect use of run flat tires
can lead to vehicle damage or accidents.
Check with an authorized Audi dea ler or
t ire spec ia list to see if your vehicle can be
equipped with run flat tires .
If run flat
t ir es a re used, they must be insta lled on
all four wheels. M ixing tire types is not
permitted.

@ Note
-For technical reasons, it is not generally
possible to use the wheel rims from oth­
er veh icles. Th is can hold tr ue for wheels
of the same vehicle type.
- If the spare tire is d ifferent from the
tires that you have mounted on your ve­
hicle (for example winter tires or wide
profi le tires), then use the spare tire for a
short per iod of time only and drive w ith
extra care. Replace the flat tire w ith the
