prevent the formation of harmful deposits, sometimes called
"sludge", that over time can lead to expensive repairs.
At the time of printing, engine oi ls 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 fo llowing specifications pr inted on the oil container:
A ud i oil stan dard VW 50 2 0 0
Oil container labels may carry the specification singly or in combi­
nation with other designations and oil quality standards.
V isc osi ty
Engine oils are graded according to their viscosity . The proper
viscosity grade oil for your engine depends on climactic or seasona l
conditions where you drive. You can use oil with a viscosity grade of
SAE 5W40 across all temperature ranges for normal dr iving condi ­
tions.
However, if engine oil viscosity grade SAE 5W40 is not available, you
can a lso use viscosity grade SAE 5W-30 or SAE 0W-40 as long as it
meets Audi oil qua lity standard VW 502 00 specifications .
Because engine oil that meets the Audi oil standard may not be
avai lable everywhere when you need it, we strongly recommend
t hat you a lways carry with you an extra quart ( liter) of oil that
express ly conforms to the VW 502 00 specification, in case you have
t o top off the oil while on the road .
On ly if the level of the oil is at or be low the minimum mark on the
oi l dipstick -and no oil that express ly 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 S L or ILSAC GF -3 specifications, but even
then, on ly in viscosity grades SAE 5W -40, SAE 5W -30, or SAE 0W -40.
However, during the ent ire time between oi l change intervals, never top off with more than a total of 0
.5 qt/ liter engine oi l that does not
conform to Audi oil specification VW 502 00.
For more information about engine oi l that has been approved for
your vehicle, p lease contact either your authorized Audi dea ler 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 o ils (manufacture rs, brand names etc.) that confo rm
to Audi oil standard VW 502 00.
Changing th e engine oil
The engine oil and oil f ilter must be changed according to the
mi leage (ki lometers) and time intervals specified in your vehic le's
Warranty & Maintenance booklet. Do no t exceed these intervals -
harmfu l deposits from old engine oil can reduce engine perfor­
mance and can lead to expensive eng ine repa irs.
Changing the oil at the recommended intervals is so very important
because the l ubricating properties of oi l decrease gradua lly during
norma l vehicle use. If you are not sure when you have your oil
changed, as k your authorized Audi Service Advisor.
Under so me circumstances the engine oil should even be changed
more frequently . Change oil more often if you drive mostly short
distances, opera te the vehicle in dusty areas or m ostly 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.
D amag e or malf unct ions due to la ck of maintenan ce
It is essential that you change your oi l at the recommended intervals
using on ly engine oil that complies with Audi oil standard
VW 502 00. Your Limited New Vehic le Warranty does not cover
damage or malfunctions due to failure to fol low recommended
maintenance and use requirements as set forth in the Audi Owner's
Manual and Wa rranty & Maintenance booklet. Your dea ler wi ll 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. •
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 219) 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 consump­
tion 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
with the oil dipstick~ page 254. Top off the oil at your
earliest convenience~
page 255.
& WARNING
Before you check anything in the engine compartment, always
read and heed all WARNINGS
~ & in "Working in the engine
compartment" on
page 250.
0 Note
Driving with an insufficient oil level is likely to cause severe damage
to the engine.
[ i] Tips
• The oil pressure warning display 't!::r. is not an indicator 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 engine consumes excessive
amounts of oil, we recommend that you consult your Audi dealer to
have the cause of your concern properly diagnosed . Keep in mind
that the accurate measurement of oil consumption requires great
care and may take some time . Your Audi dealer has instructions
about how to measure oil consumption accurately. •

Changing the engine oil
We recommend that have your oil changed by an autho­
rize d Audi de aler or a qualified service s tation.
Before you check any thi ng in the engine compartment, alway s read
and heed all WARNINGS =>
& in "Working in the engine compart ­
ment" on
page 250.
The engine oil must be changed according to the intervals specified in you r War ranty
& Main tenance booklet . This is very important
because the lubricating properties of oil diminish gradually during
normal vehicle use .
Under some circumstances the engine oil shou ld be changed more
frequently . Change oil more often if you drive mostly short
distances, opera te the ve hicle in dusty areas or under predom i­
nant ly stop -and -go traffic conditions, or have your vehicle where
t emperatures remai n below freezing fo r extended periods .
Detergent add it ives i n the oil wi ll make fresh oil look dark after the
engine has been running for a short time . This is norma l and is not
a reason to change the oi l more of ten than recommended.
Because of the problem of proper disposal, along with the special
t ools and necessa ry expert ise required, we strong ly recommend
that you have your oil changed by an authorized
Audi dealer or a
qual ified se rvice sta tion .
If you choo se to change your oil yourself , please note the follow ing
important information :
& WARNING
To reduce the risk of personal injury if you must change the engine
oil in your vehicle you rself:
• We ar eye protection . _.,

for mo re even w ear
The orig inal tires on your vehic le have 1 /16 inch (1.6 mm) high "wear
indicators "~ fig. 209 running across the tread . Depending on the
make , there will be six to eight of them evenly p laced around the
tire . Marks on the tire sidewall (for example "TWI" or other symbo ls)
indicate the positions of the tread wear indicators . Worn tires must
be replaced. Dif ferent figures may apply in other countries~&.
Tire pre ssure
Incorrect tire pressure causes premature wear and can cause
sudden tire blow-out . For this reason , tire pressure mus t be checked
at least once a month~
page 274.
Driving style
Driving fast around curves, heavy acce leration and hard braking
increase tire wear .
Rotating t ires for more even wear
For all four tires on your vehicle to have the same service life, we
recommend that the front and rear tires are rota ted according to the
tire manufacturer's suggested tire rotation interva ls . Please
remember the following:
• Tire rotation interva ls may differ from the vehicle service inter­
vals out lined in your Warran ty
& M aintenance Booklet .
• The longer one tire is used in one locat ion on the vehicle, the
more it wears at certain po ints; therefore, we recommend that you
follow the tire manufacturer 's suggested t ire rotation intervals .
• Vehicles with front -wheel drive experience more tread wear on
the front wheels compared to al l-wheel drive (quattro®) .
• Please rotate tires as shown ~
page 278, fig. 210 .
• Extra care must b e taken wh en rotat ing dir ection -specific tires
~ page 298.
Wheel balan cing
The wheels on new vehicles are balanced. However, various situa­
tions during everyday dr iving can cause them to b ecome unbal ­
anced, resulti ng in vibra tions you can usually feel through the
ste ering whee l.
Unbalanced wheels must be rebalanced to avoid excessive wear on
steering , suspension and tires . A wheel must also be reba lanced
when a new tire is installed.

M ainte nanc e book le t.
Und er diff icult op era ting co nd iti ons, for example at extreme ly low
outsi de temperatures, in very dusty regions, when towing a trailer
very frequent ly, etc ., some service work shou ld be performed
between the intervals specified. This applies particu lar ly to:
• oil changes, and
• cleaning or replacing the air filter.
<£> For the sake of the environment
By regularly maintaining your vehicle, you help make sure that emis­
sion s tandards are maintained, thus minimizing adverse effects on
the environment. •
Important considerations for you and your
vehicle
The increasing use of electronics, sophisticated fue l injection and
emission control systems, and the generally increasing techn ical
complexity of today's automobiles, have steadily reduced the scope
of maintenance and repairs which can be carried out by veh ic le
owners.
Also , safety and env ir o nment al concerns place very strict
limits on the nature of repairs and adjustmen ts to engine and trans ­
mission parts which an owner can perform.
Maintenance, adjustments and repairs usua lly require special tools,
test ing devices and other equipment availab le to spec ial ly trained
workshop personne l in order to assure proper performance, reli ­
abil ity and sa fety of the vehicle and its many systems.
I mproper maintenance, adjustments and repairs can impair the
operation and reliability of your vehicle and even void your vehicle
warranty. Therefore, proof of servicing in accordance with the main­
te nance schedule may be a condit ion fo r upholding a possible
warranty claim made within the warranty period.
Controls . and equip­
ment . Safety first Vehicle operation
Above all, operational safety can be adverse
ly affected, creating
unnecessa ry risks for you and your passengers .
If in doubt about any servicing, have it done by your authorized Audi
dealer or any other properly equipped and qua lified workshop. We
strongly urge you to g ive your authorized Audi dea ler the opportu ­
nity to perform al l scheduled maintenance and necessary repairs.
Your dealer has the fac ilities, original parts and trained spec ia lists
to keep your vehicle running properly.
Performing lim it e d maintenan ce yourself
The following pages describe a limited number of procedures which
can be performed on your vehicle with ord inary tools, should the
need arise and trained personne l be unavailab le. Before performing
any of these procedures, a lways thoroughly read all of the app li ­
cable text and carefu lly fo llow the instruct ions given. Always rigor ­
ously observe the
WARNINGS provided .
