Before you check anything in the engine compartment,
always read and heed all WARNINGS => & in "Working in
the engine compartment" on
page 273.
Determining oil level
-Park your vehicle so that it is horizontally level.
- While at operating state temperature, briefly let the
engine run at idle and then shut
it off.
- Wait approx. two minutes.
- Pull out the oil dipstick . Wipe off the oil dipstick with a
clean cloth, and s lide it back in as far as it will go.
- Pull it back out and read off the oil level
=> page 277,
fig. 207 or=> fig . 208. Top off the engine oil, if applicable
=> page 278.
Oil level within range @
-Do not add oil.
Oil level within range ~
You can add oil. Afterwards, the oil level should be within
range @.
Oil level within range ©
-You must add oil. Afterwards, the oil level should be
within range @.
The oil level needs to be checked at regular intervals. The best times
to do this are whenever you refuel and prior to long trips. •

Under some circumstances the engine oi l should be changed more
frequen tly . Change oil m ore often if you drive most ly shor t
distances, operate the vehicle in dusty areas or under predom i­
n ant ly stop -and -go traffic conditions , or have yo ur vehicle whe re
temperatures remain below freezing for extended periods.
Detergent additives in the oil will make fresh oil look dark after the
engine has bee n run nin g fo r a sh ort time. This is nor mal and is not
a reason to change the oi l more often than recommended .
Beca use of the proble m of p roper d isposal, along wi th the s pec ia l
tools and necessary expertise required, we strongly recommend
t hat yo u have your oi l ch anged by an authorized
Audi dealer or a
qua lified serv ice stat ion .
If you choose to change your o il yourself , please note the follow ing
i mportan t informatio n:
& WARNING
To reduce the risk of personal injury if you must change the engine
oil in your vehicle yourself :
• Wear eye prote ction .
• To reduce the risk of burns from hot engine oil , let the engine
c ool down to the touch .
• When removing the oil drain plug with your fingers, stay as far
away as po ssible . Always keep your forearm parallel to the ground
to help prevent hot oil from running down your arm.
• Drain the oil into a container designed for this purpose , one
large enough to hold at least the total amount of oil in your engine.
• Engine oil is poisonous . Keep it well out of the rea ch of ch ildren .
• Continuous contact with used engine oil is harmful to your
skin . Always prote ct your skin by washing oil off thoroughly with
soap and water.
0 Note
Never m ix o il add it ives w ith your engine o il. These add it ives can
damage you r engine and adversely affect your A udi Limited New
Ve hicle Warranty.
'i> For the sake of the environment
• B efore chang ing you r oil, fi rst make sure you k now w here you
can properly dispose of the used o il.
• Always dispose o f used eng ine oil properly. Do not dump it o n
garden soi l, wooded areas, into open st reams or down sewage
drains .
• Recycle used engine oi l by ta king it to a used engine oi l collec ­
tion fac ility in your area, or contac t a service stat io n .•
Engine cooling system
Coolant
T he engine coolan t performs two fun ctions: it keeps the
engine from overhe ating and it pr otec ts the engine from
f reez ing i n th e win ter.
Th e cooling system is sea led and general ly requires l itt le attention.
T he coo ling system has been fi lled at the factory with a permanent
coo la nt which does not need to be c hange d. The c oolan t consis ts of
a mixture of water and the manufacturer's glycol -based coolant
additive G12 + an tifreeze wi th anticorros io n add itives (50% for USA
models; 60% for Canadian models). This mixture both assures the
necessary frost protection and protects me tal components in the
engine's cool ing system from corrosion and scaling . It also raises
the boiling poi nt of the coolant .
Do n ot reduce t he co ncentration o f the coolan t in the su mmer by
adding plain water .
The proportion of coolant additive must be at .,_

-Read the engine coolant level in the open coolant expan­
sion
tank => fig. 211. With a cold engine, the coolant level
should be between 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
illustration=> page 275 .
To obtain an accurate reading, the engine must be sw itched 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 recommend 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 cooling system should be inspected immedi­
ately 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 scalding 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.
& WARNING (continued)
• Turn the cap slowly and very carefully in a counter-clockwise
direction while applying light, downward pressure on the top of
the cap.
• To avoid being burned, do not spill antifreeze or coolant on the
exhaust system or hot engine parts. Under certain conditions, the
ethylene glycol in engine coolant can catch fire.
0 Note
Do not add any type of radiator leak sealant to your vehicle's engine
coolant. Adding radiator repair fluid may adversely affect the func ­
tion and performance of your cooling system and could result in damage not covered by your New Vehicle Limited Warranty. •
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 273.
-Turn off the engine.
-Let the engine cool down.
-Place a thick rag over the coolant expansion tank
=> page 281 , fig. 211 and carefully twist the cap counter­
clockwise
=> & .
-Add coolant.
-Twist the cap on again tightly.
Replacement engine coolant must conform to exact spec ifications
=> page 280, "Coolant". If in an emergency coolant additive G12 + is .,,
