Changing the engine oil
The engine oil and oil filter must be changed according to the mileage
(kilometers) and time intervals specified in your vehicle's Warranty
&
Maintenance booklet. Do not exceed these intervals -harmful
deposits from old engine oil can reduce engine performance and can
lead to expensive engine repairs.
Changing the oil at the recommended intervals is so very important
because the lubricating properties of oil decrease gradually during
normal vehicle use. If you are not sure when you have your oil
changed, ask your authorized Audi Service Advisor .
Under some circumstances the engine oil should even be changed
more frequently. Change oil more often if you drive mostly short
distances, operate the vehicle in dusty areas or mostly under stop­
and-go traffic conditions, or when you use your vehicle where temper­
atures stay below freezing point for long periods.
Detergent additives in the oil 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 oil more often than recommended.
Damage or malfunctions due to lack of maintenance
It is essential that you change your oil at the recommended intervals
using only engine oil that complies with Audi oil standard
VW
502 00 . Your Limited New Vehicle Warranty does not cover
damage or malfunctions due to failure to follow recommended main­
tenance and use requirements as set forth in the Audi Owner's
Manual and Warranty
& Maintenance booklet. Your dealer will have
to deny warranty coverage unless you present to the dealer proof in
the form of Service or Repair Orders that all scheduled maintenance
was performed in a timely manner. •
Safety first
Engine oil consumption
The engine in your vehicle depends on an adequate
amount of oil to lubricate and cool all of its moving parts.
In order to provide effective lubrication and cooling of internal
engine components, all internal combustion engines consume a
certain amount of oil. Oil consumption varies from engine to engine
and may change significantly over the life of the engine. Typically,
engines with a specified break-in period (see~
page 250) consume
more oil during the break-in period than they consume after oil
consumption has stabilized.
Under normal conditions, the rate of oil consumption depends on the
quality and viscosity of the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient temperature and road
conditions. Further factors are the amount of oil dilution from water
condensation or fuel residue and the oxidation level of the oil. As any
engine is subject to wear as mileage builds up, the oil consumption
may increase over time until replacement of worn components may
become necessary.
With all these variables coming into play, no standard rate of oil
consumption can be established or specified. There is no alternative
to regular and frequent checking of the oil level, see
Note.
If the yellow engine oil level warning symbol in the instrument
cluster _ lights up, you should check the oil level as soon as possible
~ page 284. Top off the oil at your earliest convenience~ page 285.
& WARNING
Before you check anything in the engine compartment, always
read and heed all WARNINGS~
& in "Working in the engine
compartment" on page
280.

Driv ing with an i nsufficient o il level is likely to cause severe damage
to the engine .
[I) Tips
• The oil pressure warning display 'e:r. is not an ind icator of the oil
level. Do not rely on it . Instead, check the oil level in your engine at
regular intervals, preferably each time you refuel, and always
before going on a long trip.
• If you have the impression your eng ine consumes excessive
amo unts of o il, we re commen d that yo u cons ult an aut ho riz ed Aud i
dealer to have the cause of your concern properly diagnosed . Keep in
m ind th at the accurate measure ment o f oil consumption re quires
great care and may take some time. An author ized Audi dealer has
ins truc tions about how to meas ure o il consumption acc ura tely .•

Engine cooling system
Coolant
The engin e coolan t p erforms two fun ctions: it ke ep s t he
en gine from overheati ng and i t protects the engine fr om
fr eez in g in th e winte r.
Th e cooling system is sea le d and genera lly requ ires lit tle at tention.
Th e cooling system has been f illed at th e factory w it h a p erm anent
coo lant which does not need to be changed. T he coolant cons ists o f a
mix tur e of wa ter a nd the manufacturer's gly co l-basedcoolan t addi ­
tive
Gl2+ + antifreeze with anticorros ion addit ives (50% for USA
m odels; 60 % fo r C an ad ian models). This mixture both as su re s th e
necessary frost protect ion and protects meta l components in the

It als o ra ises the
boiling point of th e coolant.
Do not re duce the concentration of the coo lant in the summer by
add ing p la in wate r.
The proportion of coolant additive must be at
least 50 % but not more than 60%
to mai ntain antifreeze protection
an d co olin g efficiency . If the co ola nt frost p ro te ct ion i s to o low , the
coo lant co uld freeze and damage the veh icle heating and engine

The expansion tank in your vehicle is equipped with an electric coolant
level sensor.
When the coolant level is too low, the warn ing light in the Auto-Check
System ~
page 29 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
coo lant loss, the cooling system should be inspected immed iate ly 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.
• 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
coo lant. Adding radiator repair fluid may adverse ly 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 280.
-Turn off the engine .
- Let the engine cool down.
- Place a thick rag over the coolant expansion tank
=> page 287, fig. 223 and carefully turn the cap counter­
clockwise ::::,
&.
- Add coolant .
- Twist the cap on again
tightly.
Replacement engine coolant must conform to exact specifications
~ page 286, "Coolant". Even in an emergency, if coolant additive
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. Excess coolant will be
forced out through the press ure re lief va lve in the cap when the
eng ine becomes hot .
& 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. _.,

& WARNING
• To reduce the risk of serious injury and vehicle damage.
-Always lift the vehicle only at the special workshop hoist and
floor jack lift points illustrated=>
page 338, fig. 254 and
=> page 338, fig. 255.
- Failure to lift the vehicle at these points could cause the
vehicle to tilt or fall from a lift if there is a change in vehicle
weight distribution and balance. This might happen, for
example, when heavy components such as the engine block or
transmission are removed .
• When removing heavy components like these, anchor vehicle
to hoist or add corresponding weights to maintain the center of
gravity. Otherwise , the vehicle might tilt or slip off the hoist ,
causing serious personal injury.
0 Note
• B e aw are of the following poi nts b efo re li fting the ve hicl e:
- The vehicle should never be lifted or jacked up from under­
neath the engine oil pan, the transmission housing , the front or
rear axle or the body side members . This could lead to serious
damage.
- To avoid damage to the underbody or chassis frame, a rubber
pad must be inserted between the floor jack and the lift points.
- Before driving over a workshop hoist, check that the vehicle
weight does not exceed the permissible lifting capacity of the hoist.
- Before driving over a workshop hoist, ensure that there is
sufficient clearance between the hoist and low parts of the
vehicle. •
