- Follow legal requirements when using,
storing and transporting fuel containers.
-Make sure the fuel container conforms to
industry standards (ANSI/ASTM F852-86).
CD Note
- Remove any overflowing fuel from the vehi
cle
paint immediately.
- Never drive
until the fuel tank is completely
empty. The irregular supply of fuel that re
sults from that can cause engine misfires.
Uncombusted
fuel will enter the exha ust
system and increase the risk of damage to
the catalytic converter.
@ For the sake of the environment
If the fuel nozzle is used correctly, it will indi
cate that the tank is full the first time it
switches off automatically. Do not try to add
more fuel, because it can spill over. Also, the
expansion space in the tank will fill, which can
result in fuel spilling out when it becomes
warm and polluting the environment.
Tips
If adverse weather conditions cause the fuel
filler door to freeze shut, press on the center
of the filler door with the heel of your hand
and then try opening it again.
(0 Tips
-If the engine is running while fueling, va
pors
can escape or the fuel can spill over.
Because
of this, the fuel nozzle switches off
before the tank is full.
-
Do not fuel the vehicle when the ignition is
switched on. Otherwise, the fuel gauge may
not show the correct level after fueling the
vehicle.
- Your vehicle
is equipped with a misfueling
guard.
It allows the vehicle to be fueled on
ly with the correct fuel pump nozzle.
- A worn
or damaged nozzle or a nozzle that
is too small may not be able to open the
diesel misfueling protector. If this is the
234
case, try turning the nozzle before inserting
it in the fuel filler neck, use a different fuel
pump or see an authorized Audi dealer or
authorized Audi Service Facility for assis
tance.
-The misfueling guard does not open when

Catalytic converter
It is very important that your emission control
system (catalytic converter) is functioning prop
erly to ensure
that your vehicle is running in on
environmentally sound manner.
.,.. Always use lead-free gasoline Q page 231, Gas
oline grade .
.. Never run the tank down all the way to empty.
.. Never put too m uch motor oil in your engine
Q page 240, Adding engine oil "t::r..
.. Never try to push-or tow-start your vehicle.
The
catal ytic converter is an efficient "clean-up"
device built into the exhaust system of the vehi
cle. The catalytic
converter burns many of the
pollutants in the exhaust gas before they are re
leased into
the atmosphere .
Checking and Filling
The exclusive use of unleaded fuel is critically im
portant for the life of the catalytic converter and
proper functioning of the engine.
A WARNING
f= - I
The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
- Never
touch the exhaust tail pipes once they
have become hot. This could result in burns.
-Do not park or operate the vehicle in a reas
where the hot exhaust system may come in
contact with dry grass, brush, fuel spill or
other material which can cause a fire .
-
Do not appl y additional undercoating or
r ustproofing on or near the exhaust mani
fold, exhau
st pipes, catalytic converter or
heat shields. During driving, the substance
used for un dercoating could overheat and
cause a fire.
CD Note
-Be aware that just one tank filli ng with
leaded fuel w ill already seriously degrade
the performance of th e c atalytic converter .
-
Do not exceed the correct engine oil leve l
Qpoge240 .
-Do not drive until the fuel tank becomes
completely empty. The engi ne could mis
fire. Unbu r
ned fuel coul d also get into the
exhaust system and this could cause the
ca ta lyt ic co nver ter to overheat.
-Do not swi tch off the ignition whil e the vehi

- Let
the engine cool down.
- Never
open the hood when you see that
steam or coolant drips from the engine
compartment-there is a danger of burns!
Wait unti l no steam or coolant flows out.
- Keep children away from the engine com
partment.
- Never spill fluids on a hot engine. These flu
ids (such
as the freeze protection contained
in the coolant) can catch fire.
- Avoid
short circuits in the electrical system,
especially the battery.
-When working in the engine compartment,
remember that the radiator fan can switch
on even
if the ignition is switched off, which
increases
the risk of personal injury.
236
- Never open the cap on the coolant expan
sion
tank when the engine is warm. The
cooling
system is under pressure.
-To protect your face, hands, and arms from
hot steam or coolant, cover the cap with a
large cloth when opening.

circumstances. This increases the risk of
burns.
-
If tests need to be performed with the en
gine running, there is additional danger due
to moving components (such as the ribbed
belt, alternator and radiator fan) and from
the high voltage ignition system.
-Do not under any circumstances give gas in
advertently (for example, by hand from the
engine compartment) if the vehicle is sta
tionary but the engine is running and a gear
is engaged. Otherwise the veh icle will start
to move immediately and could result in a
crash.

Checking the engine coolant level
""Park your vehicle on a level surface.
"" switch the ignition off.
.. Read the coolant level on the coolant expansion
tank
Q page 238, fig. 184. The coolant level
must be between the markings when the en
gine
in cold. When the engine is warm it can be
slightly above
the upper marking.
Adding coolant
Requirement: there must be a res idual amount of
coo l
ant in the expans io n tank c:?(i) .
""Let the engine cool down.
.. Place a cloth over the coolant expansion tank
cap and unscrew
the cap counterclockwise
c:?,8..
""Add coolant mixed in the correct ratio
i:?page 242 up to the upper marking.
""Make sure that the fluid level remains stable.
Add more coolant if necessary.
"" Close the cap securely .
A coolant loss suggests a leak. Immediately drive
your vehicle
to an authorized Audi dealer or au
thorized
Audi Service Facility and have the cool
ing system inspected.
If the cooling system is not
leaking, a loss can come from
the coolant boiling
through overheating and being pushed
out of the
cooling system.
.&. WARNING
-The cooling system is pressurized and can be-
come very hot.
To reduce the risk of burns
from hot coolant:
-
Do not open the coolant expansion tank cap
w ith
the engine hot. There is a risk of burns .
- Stop
the engine and allow it to cool.
-
Protect your face, hands and arms from es-
caping coolant and
steam by covering the
coolant tank cap with a large, thick cloth.
- Turn
the coolant tank cap counterclockwise
slowly and keep light pressure on
the cap.
-
To reduce the risk of burns, do not allow any
antifreeze or coolant to dr
ip onto the ex-
Checking and Filling
ha ust system or hot engine components.
The ethylene glycol in engine coolant can
catch fire under certain circumstances.
- The coolant additive and the coolant can be
dangerous to your health.
For this reason,
keep
the coolant in the original container
away from children. There is a
risk of poi
soning.
-When working in the engine compartment,
remember
that the radiator fan can switch
on even if
the ignition is switched off, which
increases
the risk of personal injury.
CD Note
Do not add coolant if the expans ion tank is
empty . Air could enter the cooling system and
damage
the eng ine. If this is the case, do not
continu e driving. See an authorized
Audi dea l
er or authorized
Audi Service Facility for assis
tance.
Radiator fan
The radiator fan switches on automatically by it
self.
An auxiliary electric radiator fan switches on and
off depending on coolant temperature and other
vehicle operating conditions.
After you switch
the engine off, the auxiliary fan
can continue running for
up to 10 minutes -even
with
the ignit ion off. It can even switch on again
later by itself c:? & . if
- the temperature of
the engine coolant rises due
to
the heat build-up from the engine in the en
gine compartment, or
-
the engi ne compartment heats up because the
vehicle is parked in intense sunlight.
.&. WARNING
-To reduce the risk of personal injury never
touch
the radiator fan.
- The auxiliary electric fan
is temperature
controlled and can switch on suddenly even
when
the engine is not running.

quired
and the ne cessary expertise, we rec
ommend that you have the brake fluid
changed by your authorized Audi dealer.
Battery
General information
The battery in your Audi does not need any main
tenance under normal operating conditions. Audi
recommends having the electrolyte level check
by an
authorized Audi dealer or authorized Audi
Service Facility
when there are high outside tem
peratures or when driving all day. The electrolyte
level should also be checked each time the bat
tery is charged ~page 247.
Have the battery checked when you bring your ve
hicle
in for an inspection . It is a good idea to re
place
the battery if it is more than S years old.
Sometimes when the airbags deploy, the battery
will be disconnected from the vehicle electrical
system for safety reasons ~.&in Repair, care
and disposal
of the airbags on page 203.
Disconnecting the battery
The battery should not be disconnected. Several
vehicle functions (power windows, for
example)
will be lost when the battery is disconnected. The
functions must be reprogrammed after connect
ing the battery. To avo id this, the battery should
only be disconnected from the vehicle electrica l
system when it is absolutely necessary.
Not running the vehicle for long periods of
time
If you do not drive your vehicle for several days or
weeks, electrical consumers are gradually scaled
back
or switched off. This reduces energy use and
ensures the vehicle will be able to start after long
periods of time~ page 92. Some convenience
functions, su ch
as interior lighting or power seat
adjustment, may not be available under certain
circumstances. These convenience functions will
be available again once you switch
the ignition on
and start the engine.
Checking and Filling
Winter operation
A lot of stress is placed on the battery during
cold weather, which results in reduced starting
ability. Have the battery checked and recharged if
necessary
before the cold weather begins.
A WARNING
- Work on the battery requires expert know l
edge. Contact an authorized Audi dealer or
authorized Audi Service Facility for informa
tion regarding the vehicle battery. There is a
risk for chemical
burns or explosions.
- Never
open the vehicle battery. Do not try to
change the battery electrolyte level. Other
wise explosive
gas will escape from the bat
tery and increase the risk of an exp losion. ___ ....J
