observe the following notes about the tempera­
ture ranges.
Cold range
If o nly the LEDs in the left area of the gauge turn
on, the engine has not reached operating tem­
perature yet. Avoid high engine speeds, full ac­
celerating and heavy engine loads.
Normal range
The engine has reached its operating tempera­
ture once the LEDs up to the center of the gauge
turn on under normal driving conditions . The
LEDs farther to the right may turn on if the en­
gine is under heavy load or the outside tempera­
ture is high. This is no cause for concern as long

brake pedal while doing this.
Starting the engine
"" Press the brake pedal and move the selector
lever
into the P or N position~.&_.
... Press the I START ENGINE STOPI button
~fig. 60. The engine will start.
If the engine should not start immediately, the
starting process is automatically stopped after a
short time. Repeat
the starting process.
.&. WARNING
-I
-Never allow the engine to run in confined
spaces -danger
of asp hyxia tion.
- Never
turn off the engine before the vehicle
has come to a complete stop.
- The brake booster and power steering only
work when
the engine is running. If the en­
gine
is off, you have to use more force when
steering
or braking. Because you cannot
steer and brake
as you usually would, this
could lead to crashes and serious injuries.
CD Note
Avoid high engine speed, full throttle, and
heavy engine load
as long as the engine has
not reached operating temperature yet. You
could damage the engine.
@ For the sake of the environment
Do not let the engine run while parked to
warm up. Begin driving immediately. This re­
duces unnecessary emission
s.
Tips
-Some noise after starting the engine is nor­
mal and is no cause for concern.
-
If you leave the vehicle with the ignition
switched on,
the ignition will switch off af­
ter a certain amount of time. Make sure that
electrical equipment such as the exterior
lights are switched off.
Driving
Stopping the engine
... Bring the vehicle to a full stop.
""Move the selector lever into the P position.
... Press the I START ENGINE STOPI button
~page 58, fig. 60.
Emergency off
If it is necessary in unusual circumstances, the
eng i
ne can be switched off while the vehicle is
moving. Briefly press the I START ENGINE STOPI
button twice in a row or press and hold for longer
than
two seconds.
.&. WARNING
!-='
- Never turn off the eng ine before the vehicle
has come to a complete stop.
-
Please note that the brake booster and pow­
er steering
only work when the engine is
r unn ing. When
the engine off, you must use
more force
to steer or brake the vehicle. Be­
cause the usual steering and braking capa­
bility is not available, the risk of accidents or
injuries increases.
- For safety reasons, always park
the vehicle
with the selector lever in the P position.
Otherwise, there
is the risk that the vehicle
could roll.
-
After the engine has been switched off, the
radiator fan can continue to run for up to 10
minutes -even with the ignition switched
off. It can also switch on again after some
time if the coolant temperature rises as the
result of heat buildup or ifthe eng ine com­
partment is heated by the sun's rays and the
engine is hot.
CD Note
If the engine has been under heavy load for
an extended period of time, heat builds up in
the engine compartment after the engine is
switched off -there is a risk of damaging the
engine. For this reason, let the engine run for
at idle for approximately two minutes before
shutting it off.

@ For the sake of the environment
Even when the Emission Control System is op­
erating properly, the exhaust gas can have a
sulfur-like
exhaust gas smell under some op­
erating states. This depends on the sulfur
content of the fuel being used. Using a differ­
ent brand of fuel may help, or filling the tank
with lead-free super grade gasoline.

A WARNING
-Turn the engine off.
-switch the ignition off.
-
Set the parking brake.
-
Place the selector lever in the P position.
- 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.

- 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.
-Do not remove the engine cover under any
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.
-
Pay attention to the following warnings list­
ed when work on the fuel system or on the
electrical equipment is required.
- Always
disconnect the vehicle battery
from the vehicle electrical system.
-Do not smoke.
-Never work near open flames.

-Before changing your oil, first make sure
you know where you can properly dispose of
the used oil.
- Always
dispose of used engine oil properly.
Do not dump it on garden soil, wooded
areas, into open streams or down sewage
drains.
- Recycle
used engine oil by taking it to a used
engine oil collection facility in your area, or
contact a service station.
Coo Ling system
Coolant
The engine coolant performs two functions: it
keeps
the engine from overheating and it pro­
tects the engine from freezing in the winter.
The cooling system is sealed and generally re­
q uires
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
specially conditioned water and the manufactur­
er's glycol-based coolant additive G13 antifreeze
with anticorrosion additives (50% for USA mod­
els; 60% for Canadian models). This mixture
both assures the necessary frost protection and
protects metal components in the engine's cool­
ing
system from corrosion and scaling. It also
raises
the boiling point of the coolant.
Do not reduce the concentrat ion of the coolant in
the summer by addi ng p la in water. The propor­
tion of coolant additive must be at least 50°/o
but not more than 60°/o to maintain antifreeze
protection and cooling efficiency. If the coolant
frost protection is too low, the coolant could
freeze and damage the vehicle heating and en­
gine cooling system.
For year-round driving,
antifreeze is added at the
factory for temperatures down to:
- -
31 °F ( -35 °C) USA
- -40 °F ( -40 °C) Canada.
242
If you must add coolant, use a mixture of water
and coolant additive. Mixing the coolant additive
with distilled
water is recommended.
A WARNING
~ h . Before you check anything in t e engine com-
partment, always read and heed all WARN­
INGS C)page 236.
CD Note
-Before winter sets in, have the coo lant
checked to see if the coolant additive in you r
vehicle is
sufficient to meet the climate con­
d itions. This is especia l
ly important if you
live
in a regio n where the winter is extre m e­
ly cold . If necessary, increase the proportion
o f coo la
nt ad ditive to 60o/o.
-When add ing coolant additive to your cool­
ing
system, remember:
-We recommend using only coolant addi­
tive G12++
or G13 (check the label) for
your vehicle. This coolant additive is avail­
able at authorized Audi dealers. Other
types of antifreeze can significantly re­
duce corrosion protection. The resulting
corrosion can cause a loss of coolant and
serious engine damage.
-Do not add any type of radiator leak sealant
to your vehicle's engine coolant. Adding ra­
dia to r repair fluid may adversely
affect the
func tion and performance of your cooling
system and could result in damage not cov ­
ered by your New Veh icle Limited W arranty .

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.

-The auxiliary radiator fan switches on auto­
matically when the engine coolant reaches a
certain temperature and will continue to run
until the coolant temperature drops.
Brake fluid
Checking brake fluid level
Fig. 188 Engine compartment: cover on the brake fluid
reservoir
Before you check anything in the engine compart­
ment, always read and heed all WARNINGS
¢page 236.
~ Read the brake fluid level from the brake fluid
reservo ir ¢ fig. 188, ¢page 238, fig. 184. The
brake fluid level must be between the "MIN"
and "MAX" markings.
The location
of the brake fluid reservoir can be
seen in the engine compartment illustration
¢page238.
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 below
the "MIN" mark, the brake warning/indicator
light .. (U.S. models) I. (Canadian models)
will come on ¢ page 11. Do not continue to oper­
ate the vehicle. The complete brake system
should be thoroughly checked by an authorized
Audi dealer or other qualified facility and the
cause corrected. Ifthe brake fluid level is too
low, the brake warning/indicator light will illumi­
nate. Contact an authorized Audi dealer immedi­
ately.
244
Changing brake fluid
Have the brake fluid changed by an experienced
technician .
Brake fluid absorbs moisture from the air. If the
water content in the brake fluid is too high, cor­
rosion in
the brake system may result after ape­
riod of time. The boiling point of the brake fluid
will
also decrease considerably and decrease
braking performance.
Therefore, the brake fluid must be changed every
two years. Always use new brake fluid which con­
forms to Federal Motor Vehicle Standard "FMVSS
116 DOT 4".
The brake fluid reservoir can be difficult to reach,
therefore, we recommend that you have the
brake fluid changed by your authorized Audi
dealer. Your dealer has the correct tools, the
right brake fluid and the know-how to do this for
you.
8._ WARNING
- Brake fluid is poisonous. It must be stored
only in the closed original container out of
the reach of children!
-Brake failure can result from old or inappro­
priate brake fluid. Observe these precau­
tions:
-Use only brake fluid that meets SAE speci­
fication
J 1703 and conforms to Federal
Motor Vehicle Standard 116. Always check
with
your authorized Audi dealer to make
sure you are using the correct brake fluid.
The
correct type of brake f lui d is also ind i­
cated on the brake fluid 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 long.
This
can seriously affect the efficiency of
the brakes as well as your safety. This
could
result in an accident.
CD Note
Brake flu id will damage the paint of your veh i-
cle .
