-Apply the parking brake.
- Move selector lever to P (Park).
- Always let the engine cool down. Hot
components will burn skin on contact.
- To reduce the risk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment. Wait until no steam or
coolant can be seen or heard before care­
fully 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 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:
Checking and filling 257
- First, fully apply the parking brake,
move selector lever 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.
- Minimize exposure to emission and
chemical hazards~&. .
A WARNING
California Proposition 65 Warning:
- Engine exhaust, some of its constituents,
and certain vehicle components contain
or emit chemicals known to the State of
California to cause cancer and birth de­
fects and reproductive harm. In addition,
certain fluids contained in vehicles and
certain products of component wear con­
tain or emit chemicals known to the State of California to cause cancer and
birth defects or other reproductive harm.
- Battery posts, terminals and related ac­
cessories contain lead and lead com­
pounds, chemicals known to the State of
California to cause cancer and reproduc­
tive harms. Wash hands after handling.
Q) Note
When adding fluids, always make sure that
they are poured into the proper container
or filler opening, otherwise serious dam­
age 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 flu­ ids, have your vehicle inspected by an au­
thorized Audi dealer. •

8_ WARNING
Stop! Before working in the engine com­
partment, always read and heed all WARN ­
INGS
~ .&. in Working in the engine com­
partment on page
256 . The engine com­
partment of any motor veh icle is a poten­
tially dangerous area and can cause ser i­
ous personal injury.
8_ WARNING ,,,__
If you must change the engine oil in your
vehicle:
- Always wea r eye protection .
- T o reduce the ris k of burns from hot en-
gine oil let the engine cool down to the
touch.
- Whe n removing the oil drain plug with
yo ur fingers, stay as far away as poss ible.
Always keep your forearm paralle l to the
ground to he lp prevent hot oil from run­
ning down your arm.
- Drain the oi l into a container designed
for this pu rpose, one large enough to
hold at least the total amount of oil in
your engine.
- To reduce the risk of poisoning, never use
empty food or beverage containers that
might m islead someone into dr ink ing
from them.
- Engine oil is poisonous. Keep it well out
of the reach of children.
- Cont inuous contact with used engine oil
is harmful to your skin. Always protect
your sk in by washing thoroughly with
soap and water .
(D Note
Never mix oil additives with your engine
oil. These additives can damage your en­
gine and adverse ly affect your Audi Limit­
ed New Vehicle Warranty.
@i For the sake of the environment
- Before changing the oil, first make sure
you know where you can properly dispose of the old oil.
-
.
- Always dispose of used oil p roperly. Nev ­
er dump it on garden soil, in wooded
areas, into st reams or down sewage
dra ins.
- Recycle used oi l by taking it to a used en­
gine oil collection facility in your area, or
contact a service station.
- We strongly recommend that yo u have
your oil changed by an authorized Audi
dealer or a qualified workshop with the
special tools and expert ise required, and
proper means of disposal.
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.
T he cooling sys tem is sealed and genera lly re­
quires little attention.
The cooling system has been fi lled at the fac­
tory with a permanent coolant which does not need to be changed. The coo lant cons ists of a
mixtu re of specially conditioned water and the
manufacturer's g lycol -basedcoo la nt add
i-
tive G l3 antifreeze with anticorrosion addi ­
tives (SO% for USA mode ls; 60% for Canadian
models). This mixture both assures the neces­
sary frost protection and protects metal com­
ponents in the eng ine's cooling system from
corros ion and scaling.
It also ra ises the bo il­
i ng po int of the coolant .
Do not reduce the concentration of the cool­
ant in the summer by adding p lain wate r. Th e
proportion of coo lant additiv e mu st be at
l e as t 50 °/4 but not m ore than 60°/4
to main­
ta in ant ifreeze protect io n and cooling eff ic ien­
c y.
If the coo lant fros t protection is too low,
the coolant could freeze and damage the vehi­
cle heating and engine cooling system.
For year- round driving, antifreeze is added at
t h e factory fo r temperatures down to:
- -31°F(-35°C)USA
- - 40 °F ( - 40 °C) Canada.

-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 clearly marked "poison".
(D Note
- Coolant pollutes the environment and
could cause an engine fire. Excess coo l­
ant will be forced out through the pres­
sure re lief va lve 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 262 must be re­
stored as soon as possib le.
@ 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
The radiator fan is driven by the engine via the
V-belt . The viscous clutch regulates the speed
of the fan accord ing to the temperature of the
coolant .
An auxiliary electric radiator fan* switches on
and off depending on coolant temperature
and other vehicle operating conditions .
After you switch the engine off, the auxilia ry
fan can continue running for up to 10 minutes
- even with the ignition off. It can even switch
on again later by itself¢& , if
- the temperature of the engine coolant rises due to the heat build-up from the engine in
the engine compartment, or
- the engine compartment hea ts up because
the vehicle is parked in intense sunlight .
Checking and fillin g 265
A WARNING
-To reduce the risk of personal injury nev­
er touch the rad iator fan.
- The auxiliary electric fan is temperature
controlled and can switch on suddenly
even when the engine is not running .
- The auxiliary radiator fan switches on au­
tomatically when the engine coolant reaches a certain temperature and will
continue to run until the coo lant temper­
ature drops.

reservoir
Before you check anything in the eng ine com­
partment ,
always read and heed all WARN­
INGS ¢ A in Working in the engine compart­
ment on page 256.
.,. Read the brake fluid level from the brake
fluid reservoir ¢
fig. 247, ¢ page 258,
fig. 242.
The brake fluid level must be be­
tween the "MIN" and "MAX" markings .
The brake fluid reservoir is located at the rear
partition of the eng ine compartment on the
left side ¢
page 258.
The fluid level may drop slightly after some
time due to t he automatic adjustment of the
brake pads. This is not cause for alarm. ..,_
