A WARNING
-Always observe the warning in ¢ page 191,
before opening t he 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
cou ld burn yourself. Let the engine cool off
firstsothatyoucannothearo rseeany
steam or engine coo lant.
0 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
atu res or high engine load, the engine could
overheat.
- The front spoiler has been designed to prop­
erly distribute the cooling air when the vehi­
cle is moving. If the spoiler is damaged, this
could reduce the cooling effect and the en­
gine could then overheat. Ask your author­
ized 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
sible eng ine RPM after the break-in period. Be­
fore reaching this area, move the selector lever
to position D/5 or ease your foot off the accelera­
tor pedal.
(D Note
The tachometer needle@¢ page 10, fig. 3
should only briefly be in the red zone: you
could damage your eng ine! The beginning of
the red zone varies depending on the engine.
@ For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise.

engine coolant heats up because of intense
sunlight or heat build-up in the engine com­
partment .
- Always take the key with you whenever you
leave your vehicle . Otherwise, the engine
could be started or electrical equipment
such as the power windows could be operat­
ed. This can lead to serious injury .
- Never leave children or persons requiring as­
sistance unattended in the vehicle. The
doors can be locked using the remote trans­
mitter, preventing people from escaping
from the vehicle on their own in the event of
an emergency. Depending on the time of
year, people inside the vehicle can be ex­
posed to very high or very low tempera­
tures.

Driving
oil pressure must first build up in the hy­
draulic valve adjusters. This is normal and not a cause for concern.

Checking and Filling
-To reduce the risk of being burned, never
open the hood if you see or hear steam or
coolant escaping from the engine compart­
ment . Wait until no steam or coolant can be
seen or heard before carefully opening the hood.
- Keep children away from the engine com­ partment.
- Never spill fluids on hot engine compo­
nents. They can cause a fire.
- Never touch the radiator fan. The auxiliary
electric fan is temperature controlled and
can switch on suddenly .
- Never open the coolant reservoir cap when
the engine is still warm. The coolant system is pressurized and hot coolant could spray
out.
- Protect your face, hands and arm from
steam or hot engine coolant by placing a
thick rag over the cap when you open the coolant reservoir.
- Do not remove the engine cover under any
circumstances. This increases the risk of
burns.
- If work on the fuel system or the electrical
system is necessary:
- Always disconnect the battery.
- Never smoke or work near heaters or open
flames. Fluids in the engine compartment could start a fire.
- Keep an approved fire extinguisher imme­
diately available.
- To avoid electrical shock and personal injury
while the engine is running or being started,
never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system .
- If you must perform a check or repair with
the engine running:
- First, fully apply the parking brake, move
selector lever of automatic transmission
192
to "P" (Park); put manual transmission in
Neutral.
- Always use extreme caution to prevent
clothing, jewelry, or long hair from get­
ting caught in the radiator fan, V-belts or
other moving parts, or from contacting hot parts . Tie back hair before starting,
and do not wear clothing that will hang or
droop into the engine.
- Minimize exposure to emission and chemi­
cal hazards

(D Note
When adding fluids, always make sure that
they are poured into the proper container or
filler opening, otherwise serious damage to
vehicle systems will occur.
@ For the sake of the environment
To detect leaks in time, inspect the vehicle
floor pan from underneath regularly . If you
see spots from oil or other vehicle fluids, have
your vehicle inspected by an authorized Audi
dealer.

0 I­co .... .... specially conditioned water and the man ufactur­
er's glycol-basedcoo lant additive Gl3 antifreeze
with anticorrosion additives (50% for USA mod­
e ls; 60% for Canadian models). This m ixture
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 concentration of the coolant in
the summer by adding plain water.
Th e propor­
tion of coolant addit ive must be at l eas t 50° /4
but not more th an 60 %
to maintain antifreeze
p rotection and cooling efficiency. If the coolant
frost protec tion is too low, the coolant co uld
freeze and damage the vehicle heating and en­
gine cooling system.
F or yea r-round driving, antifreeze is added at the
factory for temperatures down to:
- -31 °F (- 35 °C) USA
- -40 °F ( - 40 °C) Canada.
If you must add coolant, use a mixture of water
and coolant addit ive. Mixing the coolant additive
with distilled water is recommended.
A WARNING
Before you check anything in the engine com­
partment, always read and heed all WARN­
INGS
Q &. in Working in the engine compart­
ment on page 191.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in your
vehicle is sufficient to meet the climate con­
dit ions. This is especially important if you
li ve in a reg ion where the w inte r is ext reme­
l y co ld. If ne cessary, in cre ase the proport io n
of coo lant add itive to 60%.
- When addi ng coolant addit ive to you r cool­
i ng system, remember:
- We recommend using only coolant addi­
tive Gl2++ or Gl3 for your ve hicle. T his
coolant additive is available at authorized
Audi dea lers. Othe r types of antifreeze can
significant ly reduce cor ros ion p rotection .
Check ing and Filling
The resulting co rrosion can cause a loss of
coolant and serious engine damage.
- Do not add any type of radiator lea k sealant
to your vehicle's engine coolant. Adding ra­
diator repair fluid may adversely affect the
function and performance of your cooling
system and could resu lt in damage not cov­
ered by your New Veh icle Limited Warranty.
Checking the engine coolant level
The engine coolant level can be checked with a
quick glance.

With a cold engine, the coolant level
should be between the " MIN" and "MAX" mark­
ings. 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 illustration
qpage 193.
To obtain an accurate reading, the engine must
be switched off.

blink until you add coolant and the level has been
restored to normal. Even though there is an e lec ­
tr ic coolant level sensor, we still recommend you
check the coo lant level from time to time.
Coolant los s
Coolant loss may indicate a l e ak in the cooling
system. In the event of coolant loss, the cooling
syst em should be insp ected immediately by your
authorized Audi dealer. It is not enough merely
to add coolant.
I n a
s e aled system, losses can occur only if the
boiling point of the coo lant is exceeded as a re­
sult of overheating.
A 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 eng ine 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 wh ile apply ing
l ight, downward pressure on the top of the
cap .
- To avo id being burned, do not sp ill anti ­
freeze or coolant on the exhaust system or
hot eng ine parts . Under certain conditions,
the ethy lene g lycol i n engine coolant can
catch fire.
{Q) Note
Do not add any type of radiator leak seala nt
to your veh icle's engine coolant . Adding radia­
to r repa ir fluid may adversely affec t the func­
tion and performance of yo ur cooling system
and could result in damage not covered by
your New Vehicle Limited Warranty.
