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 sealed and generally re­
qu ires little attention .
The cooling system has been filled at the fac­
tory with a permanent coolant which does not need to be changed. The coolant consists of a
mixture of specially conditioned water and the
manufacturer's glycol-based coolant addi-
tive G13 antifreeze with anticorros ion 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 ­
ing point of the coolant.
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 vehi ­
cle heating and eng ine cooling system .
For year-round driving, antifree ze is added at
the factory for temperatures down to:
- -31°F(-35°C)USA
- -40 ° F ( - 40 °C) Canada.
I f you must add coo lant, use a mixture of wa­
ter and coolant addit ive. Mixing the coolant
additive with distilled water is recommended.
& WARNING
Before you check anything in the engine
compartment, always read and heed all
WARNINGS ~.&.
in Working in the engine
compartment on page 211.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in
Checkin g and fillin g 217
your vehicle is sufficient to meet the cli ­
mate conditions. This is especia lly impor­
tant if you live in a region where the win­
ter is extremely co ld. If necessary, in­
crease the proportion of coolant additive
to 60% .
- When adding coolant additive to your
cooling system, remember :
- We recommend using only coolant ad­
ditive G12++ or G13 (check the label)
for your vehicle . This coolant additive is
avai lable at authorized Audi dealers .
Other types of antifreeze can signifi­
cantly reduce corrosion protection. The resulting corrosion can cause a loss of
coolant and serious engine damage.
- Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant.
Adding radiator repair fluid may adverse­
ly affect the function and performance of
your cooling system and could result in
damage not covered by your New Veh icle
Limited Warranty.
Checking the engine coolant level
The engine coolant level can be checked with
a quick glance.

Operating your vehicle
outside the U.S.A. or
Canada
Government regu lations 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 lowe r octane
rating. Improper fuel may cause engine
damage ;
- service may be inadequate due to lack of
proper service facilities, tools or testing
equipment ;
- replacement pa rts may not be readily availa­
ble.
- Navigation systems for vehicles built for the
U.S.A. and Canada will not necessar ily work
in Europe, and may not work in other coun­
tries outside North America .
(D Note
Audi cannot be responsible for mechanical
damage that could result from inadequate
fuel, service or parts availability.

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
s afety, economy and rel iability. For detailed
vehicle maintenance consult your Warranty &
Maintenance booklet.
Under difficult operating conditions, for ex­
ample at extremely low outside temperatures,
i n very dusty regions , etc., some service work
should be performed between the intervals
specified. This applies particularly to:
- oil changes, and
- cleaning or replacing the air filter.
@ For the sake of the environment
By regularly maintaining your vehicle, you
help make sure that emission standards
are maintained, thus minimizing 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
