prevent the formation of harmful deposits, sometimes called
"sludge", that over time can lead to expensive repairs.
At the time of printing, engine oils available in the U .S . and Canada
that meet the exacting specifications of Audi oil standard VW 502 00
are synthetic engine oils. This does not mean, however, that every
synthetic engine oil will meet Audi oil standard VW 502 00. So
always be sure that you use an approved oil.
To help prevent the formation of harmful deposits use only oil with
the following specifications printed on the oil container:
Audi oil standard VW 502 00
Oil container labels may carry the specification singly or in combi­
nation with other designations and oil quality standards.
Viscosity
Engine oils are graded according to their viscosity. The proper
viscosity grade oil for your engine depends on climactic or seasonal
condi tions where you drive. You can use oil wi th a viscosity grade of
SAE 5W40 across all temperature ranges for normal driving condi­
tions .
However, if engine oil viscosity grade SAE 5W40 is not available, you
can also use viscosity grade SAE 5W-30 or SAE 0W-40 as long as it
meets Audi oil quality standard VW 502 00 specifications.
Because engine oil that meets the Audi oil standard may not be
available everywhere when you need it, we strongly recommend
that you always carry with you an extra quart (liter) of oil that
expressly conforms to the VW 502 00 specification, in case you have
to top off the oil while on the road.
Only if the level of the oil is at or below the minimum mark on the
oil dipstick -and no oil that expressly conforms to Audi oil standard
VW 502 00 specifications is available - may you top off with a high
quality engine oil, preferably synthetic -based , that meets ACEA A3,
ACEA A5 or ACEA B5, API SL or ILSAC GF -3 specifications, but even
then, only in viscosity grades SAE 5W -40, SAE 5W -30, or SAE 0W -40 .
However, during the entire time between oil change intervals, never top off with more than a total of 0
.5 qt/liter engine oil that does not
conform to Audi oil specification VW 502 00.
For more information about engine oil that has been approved for
your vehicle, please contact either your authorized Audi dealer or
Audi Customer Relations at 1 (800) 822-2834 or visit our web site at
www.audiusa.com or www.audicanada.ca. Here you will also find a
current list of oils (manufacturers, brand names etc.) that conform
to Audi oil standard VW 502 00.
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
Maintenance & Warranty booklet. Do not exceed these intervals -
harmful deposits from old engine oil can reduce engine perfor­
mance 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
temperatures 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
maintenance and use requirements as set forth in the Audi Owner's
Manual and Maintenance & Warranty booklet. Your dealer will have
to deny warranty coverage unless you present to the dealer proof in

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 prov ide effect ive lubrication and cool ing of in ternal
engine components, all internal combustion engines consume a
certain amount of o il. Oil consumption varies from engine to engine
and may change significantly over the life of the engine . Typically,
eng ines wi th a specified break -in period
(see ~ page 243) consume
more oil during the break -in period than they consume after oi l
consumption has stabi lized .
Under norma l condit ions, the rate of o il consumption depends on
the quality and viscosity of the oil, the RPM (revo lutions per minute)
at whic h the engine is operated, t he amb ient te mperature and road
conditions. Further factors are the amount of oil dilution from water
condensatio n or fuel residue and t he oxidation level of the o il. As
any engine is subject to wear as mileage builds up, the oil consump ­
t ion may increase over time until rep laceme nt of worn components
may become necessary .
With all these variables coming into play, no standard rate of oil consu mption can be estab lished or specified. T here is no a lternative
to regu lar and frequent checking of the oil level, see
Note .
If the yellow eng ine o il level warni ng symbol in the instrument
cluster ~ lights up, you should check the oil level as soon as
possible
with the oil dipstick ~ page 277 . Top off the o il at your
earl iest
convenience~ page 278.
& WARNING
Bef ore you che ck anything in the eng ine comp artment , alway s
read and heed all WARNINGS
~ & in "Working in the engine
c ompartment " on
page 27 3.
0 Note
Driving with an insuff ic ient oil level is l ikely to cause severe damage
to the engine.
[ i ] Tip s
• The oil pres sure warning displ ay "e:7: is n ot an indi cator of the oil
level . Do not rel y on it. Instead, check the oil level in your engine at
regular inter vals, preferably ea ch time you refuel , and al way s before
going on a long trip.
• If you have the impression your engine consumes excessive
amounts of oi l, we reco mmend that you consult your Audi dealer to
have the cause of your concern properly diagnosed . Keep in mind
that t he accurate measurement of oil consumptio n requ ires great
care and may take some time. Your Audi dealer has instructions
about how t o measure oil cons umpt ion accurately. •

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 .,_

___ C_ h_ e_c _k _ i_n ~g _ a_n_ d_ f_il _li _n_ g~--------------------------------------------
-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 .,,

Lifting the vehicle
Important safety precautions
Be aware of the following hazards before l ift ing the vehic le w ith a
w ork sho p ho is t or f lo or jack :
• The vehicle should never be lifted or jacked up from underneath
the engine oil pan, the transmission housing , the front or rear axle
or the body side members . This could lead to serious damage.
• Use lifting equipment with padded contact surfaces to avoid
damage to the underbody or chassis frame.
• Alternatively, cover the contact surfaces on workshop hoist or
floor ja ck with rubber pads before lifting.
• 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 suffi ­
cient clearance between the hoist and low parts of the vehicle .
& 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
=> fig . 239 and => fig . 240 .
• 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 distri­
bution and balance . This might happen, for example, when heavy
components such as the engine block or transmission are
removed .
• When removing such heavy components, 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 .
