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 . _.,

Tire service life
The service life of tires depends on a lot of different things
including proper installation and balancing, correct tire
pressure and driving style .

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.

re liabi lity. For detailed v ehicl e maintenance consult your Warranty &
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 .
