Determining oil level
• Park your vehicle so that it is horizonta lly
level.
• While at operating state temperature, brief­
ly let the engine run at id le and then shut it
off .
• Wait approx. two minutes.
• Pullout the oil dipstick. Wipe off the oil d ip­
st ick with a clea n cloth, and slide it back in
as fa r as it will go.
• Pu ll it bac k ou t and read o ff th e oil level
¢ fig. 138 or ¢fig. 139. Top off the engine
oi l, if app lica ble

Depend ing on the way the vehicle is dr iven
and t he ope rat ing cond it ions, oi l consumption
c a n be up to 1/ 2 quart per 6 00 miles (0. 5 liter

- 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
T he engine coolan t 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 fac­
tory with a permanent coolant which does not
need to be changed . The coolan t consis ts of a
mixture of water and the manufacturer 's gly ­
col-basedcoolant additive G12 ++ antifreeze
with anticorrosion additives (50% for USA
models; 60% for Canad ian models). This mix­
ture both assures the necessary frost protec­
tion and protects metal components in the
engine 's cooling system from corrosion and
scaling. It also raises th e boiling point of the
c oolant.
Do not reduce the concentration of the coo l­
ant in the summer by adding plain water .
The
proportion of coolant additive must be at
least 50% but not more than 60%
to main­
tain antifree ze protection and cooling efficien­
cy . If the coolant frost protection is too low,
the coolant could freeze and damage the veh i­
cle heating and eng ine cooling system .
For year-round driving, an tifree ze is added at
the factory for temperatures down to:
- -31 ° F ( - 3 5 °C) USA
- -40 °F ( -40 °C) Canada.
You can mix the G12 ++ coolant addit ive with
other additives (G12+ or G12) . Always check
with your authorized Audi dealer.
& WARNING
Before you check anything in the engine
compartment, always read and heed all
-
Checkin g and fillin g 185
WARNINGS c:::> .& in Working in the engine
compartment on page 178.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli­
mate conditions. This is especially impor­
tant if you live in a region where the win­
ter is extreme ly cold . If necessary, in­
crease the proportion of coo lant add itive
to 60% .
- Whe n adding coolant additive to your
cooling system, remember :
- We recommend using only coo lant ad­
ditive G12++ (check the labe l) for your
vehicle . This coolant additive is avai la­
ble at authorized Audi dealers. Other
types of ant ifreeze can significantly re­
duce corrosion protection . The result­
ing corrosion can cause a loss of cool ­
ant and ser ious eng ine damage.
- Do not add any type of rad iator leak seal ­
ant to yo ur vehicle's engine coolant .
Add ing radiator repair fluid may adverse­
ly affect the function and performance of
your cooling system and could resu lt in
damage not covered by your New Vehicle
Limited Warranty .
Checking the engine coolant level
The engine coolant level can be checked with
a quick glance.

Consumer Information
Warranty coverages
Your Audi is covered by the following war­
ranties :
-New Vehicle Limited Warranty
- Limited Warranty Against Corrosion Perfo-
ration
- Emissions Control System Warranty
- Emissions Performance Warranty
- California Emissions Control Warranty (USA
vehicles only)

Operating your vehicle
outside the U.S.A. or
Canada
Government regulations in the United States
and Canada require that automobiles meet
specific emission regulations and safety
standards. Therefore, veh icles built for the
U.S.A. and Canada differ from vehicles sold in
other countries .
If you p lan to take your vehicle outside the
continental limits of the United States or Can­
ada, there is the possibility that
- unleaded fuels for vehicles with cata lytic
converter may not be available;
- fuel may have a considerably lower octane
rating. Improper fuel may cause engine
damage;
- service may be inadequate due to lack of
proper service facilities, tools or testing
equipment;
- replacement parts may not be readily availa­
ble.
- Navigation systems for vehicles built for the
U.S.A. and Canada will not necessari ly work
in Europe, and may not work in other coun­
tries outside of North America.

Maintenance
' General
Your vehicle has been designed to help keep
maintenance requirements to a minimum.
However, a certain amount of regular mainte­
nance is still necessary to assure your vehicle's
safety, economy and reliability. For detailed
vehicle maintenance consult your Warranty& Maintenance booklet.
Under difficult operating conditions , for ex­
ample at extremely low outside temperatures,
in very dusty regions, etc., some service work
shou ld be pe rformed between the intervals
specified. This applies particularly to:
- oil changes, and
- cleaning or replacing the air fi lter.
@ For the sake of the environment
By regu larly maintaining your vehicle, you
help make sure that emission standards
are maintained, thus min imizing adverse
effects on the environment.
Important considerations for you and
your vehicle
T he increasing use of electron ics, soph isticat­
ed fuel injection and emission control sys­
tems, and the generally increasing technica l
complexity of today's automobiles, have ..,_
