@ For the sake of the environment
-Under no circ umstances can the oil come
i n contact w ith the sewage network or
the soil.
- Observe and follow lega l regu lations
when disposing of empty oil containers.
Changing the engine oil
We r ecommend that hove your oil changed by
on authorized Audi dealer or a qualified serv­
ice station .
Before you check anything i n the engine com­
pa rtment,
alwa ys read and heed all WARN­
INGS c:> &. in Working in the engine comport­
men t on page 237.
The engine oil must be changed according to
the intervals specified in your Warranty
&
Maintenance book let . T his is very important
because the l ubricating proper ties of oil di­
minish gradua lly dur ing no rmal veh icle use.
Under some circ umstances the engine o il
should be changed more frequently . Change
oil more often if yo u drive most ly short dis­
tances, operate the vehicle in dusty areas or
under predominantly stop-and -go traff ic con ­
d itions, or have your ve hicle where tempera­
tures remain below free zing fo r extended pe­
ri ods.
Detergent addi tives in the o il w ill make fresh
oil look dark after the eng ine has been run­
n ing fo r a short time. This is norma l and is not
a reason to change the o il mo re often tha n
recommen ded.
Because of the problem of prope r disposal,
a long w ith the special tools and necessary ex­
p e rti se require d, we strong ly recommend tha t
you have you r o il change d by an author ized
Audi dealer or a q ualified service sta tion.

244 Checking and filling
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
quires 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 water and the manufacturer's gly ­
col-basedcoolant additive G12++ antifreeze
with anticorrosion add itives (SO% for USA
models; 60% for Canadian models). This mix­
ture bo th assures the necessary frost protec­
tion and protects metal components in the
engine's coo ling system from corrosion and
scaling. It also raises the boiling point of the
coolant.
Do not reduce the concentration of the cool­
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 engine 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.
You can mix the G12 ++ coolant additive 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
WARNINGS ¢
A in Working in the engine
compartment on page 237.
(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 especia lly impor­
tant if you live in a reg ion where the win ­
ter is extreme ly cold. 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++ (check the label) for your
vehicle . This coolant additive is availa­
b le at authorized Audi dealers . Other
types of antifreeze can significant ly re­
duce corrosion protection. The result­
ing corrosion can cause a loss of cool­
ant and serious engine damage.
- Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant.
Add ing radiator repair fluid may adverse ­
ly affect the function and performance of
your cooling system and cou ld 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.

.,. Turn off the ignition .
.,. Read the engine coolant level from the
coo lant expansion tank¢
fig. 206. With a
cold engine, the coolant level should be be-
tween the "MIN" and "MAX" markings . ..,..

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 illus­
tration ¢ page 239.
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
31 will
blink until you add coolant and the level has
been restored to normal. Even though there is
an electric coolant level sensor, we still rec­
ommend 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 cool­
ing 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 result of overheating.
& WARNING
The cooling system is under pressure and
can get very hot. Reduce the risk of scald­
ing from hot coolant by following these
steps.
- Turn
off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping 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 ap­
plying 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 condi­
tions, the ethylene glycol in engine cool­
ant can catch fire.
Checking and filling 245
@ Note
Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant. Add­
ing radiator repair fluid may adversely af­
fect the function and performance of your
cooling system and could result in damage not covered by your New Vehicle limited
Warranty.
Adding coolant

.. Twist the cap on again tightly.
Replacement engine coolant must conform to
exact specifications ¢ page
244, Coolant.
Even in an emergency, if coolant addi-
tive G12++, G12+ or G12 is
not available, do
not use a different additive. Use plain water
instead 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
coolant , 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. Ex­
cess coolant will be forced out through the pressure relief valve in the cap when the en­
gine becomes hot.

sca lding from hot coolant by following
these steps .
- Turn off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping flu id and steam by cover ing
the cap with a large, thick rag.
- Turn the cap slowly and very carefully
in a counter-clockwise direction while
applying lig ht, downwa rd pressure on
the top of the cap.
- To avo id being burned, do not spill an­
tifreeze or coolant on the exhaust sys­
tem or hot engine parts . Under certain
conditions, the ethylene glyco l in en­
gine coolant can catch f ire.
- Antifreeze is poisonous . Always store an­
tifreeze in its or iginal container and we ll
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".
@ Note
- Coolant pollutes the environment and
could cause an engine fire . Excess coo l­
ant will be forced out through the pres­
sure relief 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
c::> page 244 must be re­
stored as soon as possible .
@ For the sake of the environment
Drained 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
T he 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* switches on
and off depend ing on coolant temperature
and other vehicle operat ing condit ions .
After yo u sw itch the engine off, the auxiliary
f an can continue running for up to 10 minutes
- even with the ignit ion off. It can even switch
on again later by itself
c::> &., if
- the temperature of the engine coolant rises
due to the heat build-up from the engine in
the engine compartment, or
- the engine compa rtment heats up because
the vehicle is parked in i ntense sunlight.
_& 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 switches on au­
tomatically when the engine coo lant
reaches a certain temperature and will
continue to run until the coolant temper­
ature drops .

level must be between the "MIN" and
"MAX" markings .
The brake f luid reservoir is located at the rear
partition of the engine compartment on the
l eft side ¢
page 239 .
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 be­
l ow the "M IN" mark, the brake wa rning/indi ­
cator light (U .S . mode ls: . , Canadian

- Do not reuse batteries wh ich were fro­
zen. The battery hous ing may have
cracked and weakened when the battery
froze.
- Charge the battery in a well ventilated
area . Keep away from open flame or elec­
trica l spark. Do not smoke. Hydrogen gas
generated by the battery is explos ive.
- To reduce the danger of explosion,
never
connect or disconnect charger cables
while the charger is operating.
- Fast charging a battery is dangerous and
should only be attempted by a compe­
tent technician with the proper equip­
ment.
- Battery acid that may spill during charg­
ing should be washed off with a solut ion
of warm water and baking soda to neu-
tralize the acid. ....
