nents. They can cause a fire.
- Never touch the radiator fan. The auxili­
ary electric fan is temperature controlled
and can switch on suddenly.
- Never open the coolant reservoir cap
when the engine is still warm. The cool­
ant system is pressurized and hot cool­ ant 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 electri­
cal system is necessary:
- Always disconnect the battery.
- Never smoke or work near heaters or
open flames. Fluids in the engine com­
partment could start a fire.
- Keep an approved fire extinguisher im­
mediately available.
- To avoid electrical shock and personal in­
jury 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 trans­
mission to P (Park).
- 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 contact­ ing hot parts. Tie back hair before
starting, and do not wear clothing that
will hang or droop into the engine.

Engine oil
Engine oil specifications
The engine in your Audi needs the right kind
of oil.
The engine in your Audi is a sophisticated
powerplant that was built to exacting specifi­
cations. This eng ine needs the right k ind of
engine oil that meets specifications regarding
quality and viscosity so that it can run
smooth ly and reliab ly. Choosing the right oil
and changing oil within the time and mileage
intervals printed in your vehicle's Warranty
&
Maintenance booklet matters a lot more to­
day than it did years ago . Audi has developed
a specia l quality standard for engine oil that
will help assure that your vehicle's engine will
get the lubrication it needs for proper opera-
tion. .,..

238 Check ing and filling
Never mix oil additives with your engine
oil. These additives can damage your en­
gine and adversely affect your Audi Limit­
ed New Vehicle Warranty.
@) For the sake of the environment
- Before changing your oi l, f irst make sure
you know where you can properly dispose of the used o il.
- Always dispose of used engine oil proper­
l y. Do not dump it on garden so il, wood­
ed areas, into open streams or down
sewage dra ins.
- Recycle used engine oil by taking it to a
used engine oil collection facility in your
area, or contact a service station .
Engine 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 sea led and generally re­
q ui res little attention .
The cooling system has been filled at the fac­
tory with a pe rmanent coolant which does not
need to be changed. The coolant consists of a
mixture o f spec ia lly condi tioned water and the
manufacturer's glycol -basedcoolant addi -
tive G l3 antifreeze with anticorrosion addi­
tives (50% for USA models ; 60% for Canadian
models). This mixture both assures the neces­
sary frost protection and protects metal com­
ponents in the engine's cooling system from
corrosion and scaling . It also raises the boil­
i ng po int of the coo lant .
Do not red uce the concentration of the coo l­
ant in the summer by adding plain water.
The
proportion of coolant add iti ve mu st be at
least 50 % but not more than 60 %
to main­
tain antifreeze protection and cooling efficie n­
cy.
If t he coolant frost protect io n is too low,
the coo lant cou ld freeze and damage the veh i­
cle heating and engine cooling system. F
or year -ro und driving, antifreeze is added a t
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 wa­
ter and coolant additive . Mix ing the coo lant
additive with distilled water is recommended .
.&, WARNING
--
Before you c hec k anyth ing in the engine
compartment, a lways read and heed a ll
WAR NIN GS~ .&.
in Working in the engine
compor tment on page 231 .
(J;) Note
-Before winter sets in, have the coo lant
checked to see if the coolant additive in
yo ur vehicle is sufficient to meet the cli­
mate condi tions . This is especia lly impor ­
tant if you live in a region where the win ­
ter is extreme ly co ld . If necessary, in­
crease the p roportion of coo lant add itive
to 60%.
- When adding coolant additive to yo ur
cooling system, remember :
- W e r ecommend using o nly coola nt ad­
d itive G l2++ or Gl3 for your veh icle.
T his coolan t additive is av ail ab le a t au­
thor ized Audi dealers. O ther types of
antifreeze can significant ly reduce cor ­
rosion protection . The resulti ng cor ro­
sion can cause a loss o f coolant and se­
rious engine damage.
- Do not add any type of rad iator leak seal ­
ant to your vehicle 's eng ine coolant.
Add ing radiato r repair flu id may adverse­
ly affect the function and performance of
your cooling system and co uld resu lt in
damage not cover ed by yo ur New Ve hicle
Limited Warranty.

Checking the engine coolant level
The engine coolant level can be checked with
a quick glance .

Before you check anything in the engine com­
partment,
a lway s re ad and he ed all WARN ­
INGS ¢ A in Working in the engine compart­
ment on page 231 .
.,. Park your vehicle on a level surface.
.,. Turn off t he ignit ion.
.,. Read the eng ine coolant level from the cool­
ant expansion tank¢ fig . 201, ¢ page 233,
fig. 198 . With a cold eng ine , the coola nt
level should be between the "M IN " and
"MAX" markings . W hen the eng ine is warm,
the leve l may be slightly above the "MAX"
marking.
The location of the coolant expans ion tank
can be seen in the engine compartment illus­
tration ¢page 233.
To obtain an accurate read ing, the eng ine
must be switched off.
The expans ion tank in your vehicle is equipped
with an e lectr ic coolant level sensor .
When the coo lant level is too low, the warning
light in the Auto -Check System ¢ page 30 will
blink until you add coo lant and the level has
been restored to normal. Even though there is
a n elec tric coolant leve l sensor, we s till rec­
ommend you chec k the coolant leve l from
time to time .
Coolant loss
Coolant loss may indicate a leak in the cool ing
system. In the event of coolant loss, the cool-
Checkin g and fillin g 239
ing system shou ld be inspected immediately
by your authorized Audi dealer . It is not
eno ugh merely to add coo lant .
In a
s ealed system, losses can occu r on ly if
the boiling point of the coo lant is exceeded as
a resu lt of overheating.
(D Note
Do not a dd any type o f radiator leak se al­
ant to your veh icle's engine coo lant. Add ­
ing radiator repa ir flui d may adverse ly af­
fect the funct ion and performance of yo ur
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 alt WARN­
INGS ¢ A in Working in the engine compart ­
ment on page 231 .
.,. Turn off the engine .
.,. Let the engine cool down.
.,. Place a thick rag over the coo lant expansion
tank ¢ page 239, fig. 201 and
carefully turn
the cap counter -clockwise ¢

.,. Add coolant m ixed in the co rrect rat io
¢ page 238, Coolant.
.,. Twis t the cap o n aga in tightly.
Rep lacement engine coo lant must conform to
exact spec ificat ions ¢ page 238, Coolant.
We recommend using only coolant add itive
Gl2 ++, Gl3 or in an emergency Gl2 +. Do not
use a different add itive . In an emergency use
plain water until you can get the correct addi­
tive and can restore t he cor rect ratio . Th is
sho uld be done as soon as possib le.
If you have lost a cons iderab le amount of
coolant, then you sho uld add cold ant ifreeze
and co ld wate r on ly w hen the eng ine is cold.
Always use new engine coo lant when refill ing .
Do not fi ll coo lant above the "MAX" mark. Ex­
cess coolant will be forced o ut through the

pressure relief valve in the cap when the en ­
gine becomes hot.
A WARNING
- The coo ling system is under pressure and
can get very hot. Reduce the risk of
sca lding 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 escap ing fl uid and steam by cover ing
the cap with a large, thick rag.
- T urn the cap slowly and very carefully
in a counter-clockwise direction while
applying light, downward pressure on
the top of the cap.
- To avo id being burned, do not sp ill an ­
tifreeze or coolant on the exhaust sys­
tem or hot engine parts. Under certain
conditions, the ethylene glyco l in en­
g ine coolant can catch fire.
- Antifreeze is poisonous. Always store an­
t ifreeze in its or iginal container and well
out of the reach of children.
- If you drain the coolant, it must be caught and safely stored in a proper con­
tainer clear ly marked "poison".
- Coolant pollutes the environment and
could cause an engine fire. Excess coo l­
ant will be forced out through the pres­
sure re lief valve in the cap when the en­
gine becomes hot.
- If, in an emergency, only water can be
added, the correct ratio between water
and antifreeze~
page 238 must be re­
stored as soon as possib le.
@ For the sake of the environment
Dra ined coolant should not be reused. Al­
ways dispose of used coolant while observ­
ing all environmental regulations.
Radiator fan
The radiator fan switches on automatically by
itself.
The radiator fan is driven by the engine via the
V-belt. The viscous clutch regulates the speed
of the fan according to the temperature of the
coolant .
An auxiliary electric radiator fan* sw itches on
and off depending on coolant temperature
and other vehicle operat ing condit ions.
After you switch the engine off, the aux iliary
fan can continue running for up to 10 m inutes
- even w ith the ignition off. It can even switc h
on again later by itself
c> &. , if
- the temperature of the engine coo lant r ises
due to the heat build-up from the engine in
the engine compartment, or
- the engine compartment heats up because the vehicle is parked in intense sunlight.
A WARNING
- To reduce the risk of personal injury nev­
er touch the radiator fan .
- The auxiliary electric fan is temperature
controlled and can sw itch on suddenly
even when the engine is not running.
- The auxiliary radiator fan sw itches on au­
tomatically when the engine coo lant
reaches a certain temperature and w ill
con tinue to run until the coolant tempe r­
a ture drops.

248 Tire s and whee ls
- Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when driving, al­
ways stop as soon as it is safe to do so and check the wheels and tires for dam­
age.
