Normal temperature
The engine has reached its operating tempera
ture once the LEDs up to the center of the gauge
turn on under norma l driving conditions . The
LEDs higher up may turn on when the engine is
under heavy load or the exterior temperature is
high. This is no need to worry as long as the.
warn ing light in the instrument cluster does not
illuminate . If the LEDs in the upper area of the
d isplay and the ind icator light . in the instru
ment cluster display tu rn on , the coolant temper
ature is too high
¢page 15.
_& WARNING
-Always observe the warning in ¢ page 220,
Working in the engine compartment,
before
opening the hood and checking the engine
coolant level.
- Never open the engine hood if you see or
hear steam, or if you see engine coolant
dr ipping from the engine compartment. You
could burn yourself. Let the engine cool off
first so that you cannot hear or see any
steam or engine coolant.
(D Note
-Mounting additional lights or accessories in
front of the air inlets reduces the cooling ef
fect of the radiator. At h igh outside temper
atures or high engine load, the engine could
overheat .
- The front spoiler has been designed to prop
erly distribute the cooling air when the veh i
cle is moving.
If the spo iler is damaged, this
could reduce the cooling effect and the en
gine could then overheat. Ask your author
iz ed Audi dealer for assistance.
Tachometer (engine rev counter)
The tachometer indicates the engine RPM (revo
lutions per minutes).
If engine RPM drops below 1,500, you should
downshift to the next lower gear. The red area at
the end of the scale indicates maximum permis
sib le eng ine RPM after the break-in period. Be
fore reaching this area, move the selector lever
Instruments and indicator lights
to position "D (Drive)" or ease your foot off the
acce lerator pedal.
(D Note
The tachome ter needle should only briefly be
in the red zone: you could damage your en
gine! The beginning of the red zone varies de
pending on the engine .
@ For the sake of the environment
Upshifting early saves fuel and reduces en
gine noise.
Fuel gauge
The fue l gauge only works when the ignition is
on. If the fuel level drops below 4 gallons (15 lit
ers), the bottom LED turns red and the indicator
l ight tllturns on
¢page 21. The bottom LED
blinks red when the fue l level is very low .
The possible range based on the current fue l lev
el is shown in tab@¢
page 23, fig. 4.
(D Note
Never run the tank completely dry. An irregu
l ar supply of fuel can cause engine misfiring
and fuel could enter the exhaust system. The
catalytic converter could then overheat and
be damaged.

The exclusive use of unleaded fue l is critica lly im
portant for the l ife of the catalytic converter and
proper functioning of the engine.
A WARNING
T he temperature of the exha ust 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 areas
where the hot exha ust system may come in
contact with dry grass, brush, fue l spill or
other mater ial which can cause a fire.
- Do not apply additional undercoating or rustproofing on or near the exhaust mani
fold, exhaust p ipes, catalytic converter or
heat sh ields. During dr iv ing, the substance
used fo r undercoating could overheat and
ca use a fire.
(D Note
- Be aware that just one tank filling with
le aded fuel will already ser iously degrade
the performance of the catalytic co nverter .
- Do not exceed the correct eng ine oil level
<=;> page 225.
-Do not drive until the fuel tank becomes
complete ly empty. The engine could mis
fire. Unburned fuel could also get into the
exhaust system and this cou ld cause the
cataly tic converte r to overheat.
- Do not sw itch off the ignition while the veh i
cle is moving.
- Do not continue to operate your vehicle un
der these cond it ions, as otherwise fue l can

-Lack of proper ma intenance as well as im
proper use of the vehicle wi ll impair the
funct ion o f the emission control system
and could lead to damage.
@ For the sake of the environment
Even when the Emiss ion Control System is op
erating properly, the exhaust gas can have a
su lfu r-li ke exhaust gas sme ll under some op
erating states. Th is depends on the sulfur
content of the fuel being used. Us ing a d iffer
ent brand of fuel may help, or fi lling the tank
with lead-free super g rade gasoline.
Diesel particulate filter

oil du ring the break -in period than they consume
after oil consumption has stabilized .
Unde r no rmal condi tions, the rate of o il con
sumpt ion depends on the quality and viscosity of
the oi l, the RPM (revolutions per minute) at
which the engine is operat ed, the ambient tem
perature and road cond itions . Further factors are
the amount of oil dilut ion from water condensa
tion or fuel residue and the oxidation level of the
oil. As any eng ine is subject to wear as m ileage

time until rep lacement of worn components may
become necessa ry .
W ith all these variables com ing into play, no
standard rate of oil consumpt ion ca n be estab

Cooling 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
quires little attention.
T he 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 condit ioned water and the manufactur
er's glycol-based coolant additive Gl3 antifreeze
with anticorrosion additives (SO% for USA mod
e ls; 60% for Canadian mode ls). This m ixture
both ass ures the necessa ry frost protection and
protects metal components in the engine's coo l
ing system from corrosion and scaling .
It also
raises the boiling point of the coolant.
Do not red uce the concent ration of the coolant in
the summer by adding p lain water.
The propor
tion of coolant addit ive mu st be at least 50 %
but not more than 60 %
to mainta in antifreeze
protection and cooling efficiency. If the coolant
frost protection is too low, the coolant could
freeze and damage the vehicle heating and en
g ine cooling system .
For year-round driving, antifree ze is added at the
factory for temperatures down to :
- -31° F(- 3S°C)USA
- - 40 ° F ( - 40 °C) Canada.
If you must add coolant, use a m ixture of water
and coolant addit ive. M ixing the coolant additive
with d istilled water is recommended .
_& WARNING
Before you check anythi ng i n t he engine com
partment, always read and heed all WARN
INGS
¢ .&. in Working in the engine compart
ment on page 220 .
(D Note
-Befo re winter se ts in, have the coo lant
checked to see if the coolant additive in your
vehicle is sufficient to meet the cl imate con -
Check ing and Filling
ditions. This is especially important if you
live in a region where the winter is extreme
ly cold. If necessary, increase the proportion
of coolant additive to 60%.
- When adding coolant additive to your cool
ing system, remember :
- We recommend us ing only coolant add i
tive Gl2+ + or Gl3 for yo ur vehicle. This
coolant addit ive is avai lab le at aut horized
A udi dealers . O ther types of antifree ze can
significantly reduce corrosion pro tect ion .
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
diator repair fluid may adversely affect the
function and performance of your cooling system and cou ld resu lt in damage not cov
ered by your New Veh icle Limited Warra nty .
Checking the engine coolant level
The engine coolant level can be checked with a
quick glance.

sion t ank
Before you check anything in the engine compart
ment,
always read and heed all WARNINGS
¢ A in Working in the engine compartment on
page 220 .
Park your vehicle on a level surface .
.,. Switch off the ignition .
.,. Read the engine coolant level from the coo lant
expansion tank
¢ fig . 201, ¢page 222. With a
cold engine, the coolant level should be be-
tween the "min" and "max" markings. When .,.
227

Checking and Filling
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 illustration
¢ page 222.
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 15 will il
luminate until you add coolant and the level has
been restored to normal. Even though there is an
electric coolant level sensor, we still recommend
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 cooling
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 re
sult of overheating.
_& WARNING
The cooling system is under pressure and can
get very hot. Reduce the risk of scalding from
hot coolant by following these steps.
- Turn off the engine and allow it to cool
down.
- Protect your face, hands and arms from es
caping 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 applying
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 conditions,
the ethylene glycol in engine coolant can
catch fire.
228
(D Note
Do not add any type of radiator leak sealant
to your vehicle's engine coolant. Adding radia
tor repair fluid may adversely affect the func
tion and performance of your cooling system
and could result in damage not covered by
your New Vehicle Limited Warranty .

not use a
different additive. In an emergency use plain wa
ter until you can get the correct additive and can
restore the correct ratio. This should be done as
soon as possible.
If you have lost a considerable amount of cool
ant, then you should add cold antifreeze and cold
water only when the engine is cold.
Always use
new engine coolant when refilling.
Do not fill coolant above the "MAX" mark . Excess
coolant will be forced out through the pressure
relief valve in the cap when the engine becomes
hot.

Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a quick
glance.

Before you check anything in the engine compart
ment,
always re ad a nd hee d all W ARNING S
¢ A in Working in the engine compartment on
page 220.
., Read the brake fluid level from the brake fluid
reservoir
<=> fig . 202, ¢page 222. The brake flu
id level must be between the "MIN" and "MAX"
mark ings.
The location of the brake fluid reservoir can be seen in the engine compartment illustration
¢ page 222.
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
1111 (U.S. models)/ . (Canadian models)
will come on¢
page 14 . Do not continue to oper
ate the vehicle . The complete brake system
should be thoroughly checked by an authorized
Aud i dealer or other q ualified facili ty and the
cause corrected.
If the brake f luid level is too
low, the brake warning/indicator light will i llumi
nate. Contact an authorized Audi dealer

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 po int of the brake fluid
will a lso decrease considerably and decrease
braking performance.
Therefore , the brake fluid must be changed
eve ry
two y ears . Always use new brake fluid which con
forms to Feder-al Motor Vehicle Standard "FMVSS 116 DO T 4".
The brake fluid reservoir can be difficult to reach ,
therefore, we recommend that you have the brake fluid changed by your author ized
Audi
d ea ler . Your dealer has the correct tools, the
right brake fluid and the know -how to do this for
you.
A WARNING
- Brake fluid is po isonous. It must be stored
only in the closed original container out of
the reach of children!
- Brake fai lure can result from o ld or inappro
priate brake fluid . Observe these precau
tions:
- Use only brake fluid that meets SAE speci ficat ion
J 1703 and conforms to Federal
Motor Ve hicle Standard 116. Always check
with your authorized Audi dealer to make
sure you are using the correct brake f luid .
The correct type of brake f luid is also indi
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.
(D Note
Brake fluid will damage the paint of your vehi-
cle .
