because the lubricating properties of oil diminish gradually during
normal vehicle use .
Under some circumstances the engine oil should be changed more
frequently . Change oil more often if you drive mostly short
distances, operate the vehicle in dusty areas or under predomi ­
nantly stop -and -go traffic conditions, or have your vehicle where
temperatures remain below freez ing for extended periods.
Detergent additives in the oi l will make fresh oil look dark after the
engine has been running for a short time. This is normal and is not
a reason to change the oi l more often than recommended .
Because of the problem of proper disposal, along with the specia l
tools and necessary expertise required, we strongly recommend
that you have your oi l changed by an authori zed
Audi dea ler or a
qual ified service stat ion.
If you choo se to cha nge yo ur oi l y ou rse lf, please no te the following
important information:
& WARNING
To reduce the risk of per sonal injury if you m ust change the engine
o il in you r veh ic le y our self :
• Wear eye protection.
• To reduce the ri sk of burn s from hot engine oil , let the engine
c ool down to the tou ch.
• When removing the oil drain plug with your fing ers , sta y as far
away as po ssi ble . Alw ay s k eep your f orearm par allel to the gr ound
to help pre vent hot oil from running down your arm .
• Drain t he oil int o a contain er de signed for thi s purpo se , one
large enough to hold at l ea st th e total amount of oil in your eng ine .
• Engine oil i s poi sono us. K eep it well out of the rea ch of ch ildr en .
• Continuou s contact with u sed engine oil i s harmful to your

s oap and w ater.
0 Note
Never mix oil addi tives with your engine oil. These add itives can
damage your engine and adversely affect your Audi Limited New
Vehicle Warranty .
c£> For the sake of the environment
• Before changing your oi l, first make sure you know where you
can properly dispose of the us ed oil.
• Always dispose of used engine oil properly. Do not dump it on
garden soil , wooded areas, into open streams or down sewage
drains .
• Recycle used engine oil by taking it to a used engine oil collec ­
tion fac ility 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 protects the engine from
freezing i n the winter.
The cooling system is sea led and generally requires little attention.
The coo ling system has been fi lled at the factory with a permanent
coolant which does not need to be changed . The coolant consists of
a mixture of water and the manufac turer's glycol-basedcoolant
additive G 12+ an tifreeze with anticorrosion additives (50% for USA
models; 60% for Canadian models). This mixture both assures the
necessary frost protection and protects metal components in the
engine 's cooling system from corrosion and scaling . It also raises
the boiling point of the coolant.
Do not reduce the concentration of the coo lant in the summer by
adding plain water.
The p ropo rt ion of co ola nt additiv e mu st be at .,_

le as t 50% b ut not mor e th an 60 % to maintain antifreeze protection
and cooling efficiency . If the coo lant frost protection is too low, the
coo lant could freeze and damage the vehicle heating and engine
cooling system.
For year -round driving, antifreeze is added at the factory for temper­
atures down to:
• -31 °F ( -35 °C) USA
• -40 °F ( -40 °C) Canada.
You can m ix the
Gl 2 + coolant additive with other add itives (for
example
Gl 1 or Gl 2). A lways check with your authorized Audi
dea ler .
& WARNING
Before you check anyt hing in the engine comp artment , alw ays
re ad and heed all WARNINGS ~
& in "Working in the eng ine
co mpar tm ent " o n
pag e 297.
0 Note
• Before win ter sets in, have the coolant checked to see if the
coolant additive in your vehicle is sufficient to meet the climate
conditions. This is especia lly important if you live in a region where
the winter is extremely cold. I f necessary, increase the proportion of
coo lant additive to 60%.
• When adding coolant additive to your coo ling system,
remember:
-We recommend using only coolant additive
Gl 2+ (check the
label) for your vehicle. This coolant addit ive is available at autho ­
rized Audi dealers. Other types of antifreeze can significantly
reduce corrosion protect ion . T he resulting corrosion can cause a
loss of coolant and serious engine damage.
• Do not add any type of radiator leak sealant to your vehicle's
engine coolant. Adding radiator repair fluid may adversely affect the function and performance of your cooling system and cou
ld result
in damage not c overed by your New Vehicle Limited Warranty. •
Checking the engine coolant level
The engine coolant level can be checked with a quick
glance.

"max" marking .
The location of the coolant expansion tank can be seen in the
engine compartment illustration~
page 298.
To obtain an accurate reading, the engine must be switched off .
T he expansion tank in your vehicle is equipped with an e lectric
coo lant leve l sensor.

•
When the coolant level is too low , the warning light in the Auto­
Check System =>
page 33will blink un til you add coo lant and the
level has been restored to normal. Even though there is an electric
coolant leve l sensor, we still recommend you check the coo lant level
from time to time .
Coola nt lo ss
Coolant loss may indicate a leak in the cooling system . In the event
of coolant loss, the coo ling sys tem should be inspected immedi ­
ately by your authorized Audi dealer . It is not enough merely to add
coolant.
In a
s ealed system, losses can occur only if the boiling po int of the
coolant is exceeded as a result of overheating.
0 Note
Do not add any type of radiator leak sea lant to your vehicle's engine
coolant . Adding radiator repair fluid may adversely affect the func ­
tion and performance of your cooling system and could resu lt in
damage not covered by your New Vehic le Limited War ranty .•
Adding coolant
Be very careful when adding engine coolant.
Before you check anything in the engine compartment,
always read and heed all WARNINGS => & in "Working in
the engine compartment" on
page 297 .
- Tu rn off the engine .
- L et the engine coo l dow n.
- Place a t hick rag over the coolant expansion tank
=> page 304, fig . 235 and carefully tw ist t he cap counter­
cloc kw ise
=> & .
- Add coolant. - Twist the cap
on agai n
tightly.
Replacement engine coolant must conform to exact specifications
=>
page 303, "Coolant". If in an emergency coolant additive G12 + is
not avai lable, do
not use a different additive . Use p lain water
instead until you can get the correct additive and can restore the
correct ratio . This should be do ne 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 fil l coolant above the "MAX" mark. Excess coolant will be
forced out through the pressure relief va lve in the cap when the
engine becomes ho t.
& WARNING
• The cooling system is under pressure and can get ver y hot.
Redu ce the risk of sc alding from hot coolan t by follow ing the se
s tep s.
- Turn off th e en gine and allo w it to cool down .
- Protect your fa ce , ha nd s and arm s from e sc a pi ng fluid and

• Coolant pollutes the environment and cou ld cause an engine
fire. Excess coolant will be forced out through the pressure relief
valve in the cap when the engine becomes hot.
• If, in an emergency, only water can be added, the correct ratio
between water and antifreeze ~
page 303 must be restored as soon
as possible .
ci> For the sake of the environment
Dra ined coolant should not be reused . Always dispose of used
coolant whi le observing all environmental regulations. •
Radiator fan
The radiator fan switches on automatically by itself.
The rad iator fan is driven by the eng ine v ia the V-be lt . The v iscous
clutch regulates the speed of the fan according to the tempera ture
of the coo lant .
An auxiliary electric radiator fan * swi tches on and off depending on
coo lant temperature and other vehicle operating conditions.
After you switch the engine off, the auxiliary fan can continue running for up to 10 minut es -even with th e igni tion o ff. It can even
switch o n again later by itself~ & , if
• the temperature of the engine coo lant rises due to the heat
bui ld -up from the engine in the engine compartment, o r
• the engine compartment heats up because the vehic le is parked
in intense sun light.
& WARNING
• To reduce the ri sk of per sonal injury never tou ch the radiator
f a n.
& W AR N ING (continu ed )
• The auxiliary e le ctri c fan i s temperature controlled and can

crashes and serious personal injuries . Have worn or damaged tires
replaced immediately.
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds. Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
low speed.
Glossary of tire and loading terminology
Accessory weight
means the combined weight (in excess of those standard items
which may be replaced) of automatic transmission, power steering,
power brakes, power windows, power seats, radio, and heater, to
the extent that these items are available as factory-installed equip­
ment (whether installed or not).
Aspect ratio means the ratio of the height to the width of the tire in percent.
Numb ers of 55 or lower indicate a low sidewall for improved
steering response and better overall handling on dry pavement.
Bead
means the part of the tire that is made of steel wires, wrapped or reinforced by ply cords and that is shaped to fit the rim.
Bead separation means a breakdown of the bond between components in the bead.
Cord
means the strands forming the plies in the tire.
& WARNING (continued)
• Never mount used tires on your vehicle if you are not sure of
their "previous history." Old used tires may have been damaged
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, always stop as soon as it is safe to do so and check
the wheels and tires for damage . •
Cold tire inflation pressure
means the tire pressure recommended by the vehicle manufacturer
for a tire of a designated size that has not been driven for more than
a couple of miles (kilometers) at low speeds in the three hour period
before the tire pressure is measured or adjusted .
Curb weight means the weight of a motor vehicle with standard equipment
including the maximum capacity of fuel, oil, and coolant, air condi­
tioning and additional weight of optional equipment.
Extra load tire
means a tire designed to operate at higher loads and at higher infla ­
tion pressures than the corresponding standard tire . Extra load tires
my be identified as "XL",
"xi", "EXTRA LOAD", or "RF" on the side ­
wall.
Gross Axle Weight Rating ("GAWR")
means the load-carrying capacity of a single axle system, measured
at the tire -ground interfaces .
Gross Vehicle Weight Rating ("GVWR"l
means the maximum total loaded weight of the vehicle.

& WARNING (continu ed )
• Only when all tires on the veh icle are filled to the correct pres­
s ure , the tire pre ssure monitoring sy stem can work correctly .
• The use of incorrect tire pressure values can lead to accidents
or other damage. Therefore it i s es sential that the driver observe
the specified tire pre ssure values for the tires and the correct pres­
s ures for the function of the tire pressure monitoring system.
• Alway s inflate tires to the recommended and correct tire pres ­
sure before driving off .
• Driving with underinflated tires bend more , letting them get
too hot re sulting in tread separation , sudden ti re failure and loss
of control.
• Ex cessive speed and /overloading can cause heat build -up ,
sudden tire failure and loss of control.
• If the tire pressure is too low or too high, the tires will wear
prematurely and the vehicle will not handle well .
• If the tire is not flat and you do not have to change a wheel
immediately , drive at reduced speed to the nearest service stat ion
to che ck the tire pressure and add air as required .
0 Note
Driving without valve stem caps can cause damage to the tire
valves. To preven t this, a lways make su re t hat facto ry instal led
va lve
stem caps on a ll whee ls are securely mounted on the va lve .
'£> For the sake of the environment
Underinflated t ires will a lso increase the fuel consumption. •
Tires and vehicle load limits
There are limits to the amount of load or weight that any vehicle and
any t ire can car ry. A vehicle that i s ove rlo aded wil l n ot hand le well and
is more difficu lt to stop . Overloading can not only lead to loss
o f ve h ic le control, but ca n also damage impor ta nt parts o f the
vehic le and can lead to sudden tire fa ilure, inc luding a blowout and
sudden defla tion that ca n cause the vehic le to cra sh .
