Tires and wheels -_______________ _____.
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 more even wear
The original tires on your vehicle have 1/16 inch (1.6 mm) high "wear
indicators":::::, fig. 175 running across the tread. Depending on the
make, there will be six to eight of them evenly placed around the
tire. Marks on the tire sidewall (for example "TWI" or other symbols)
indicate the positions of the tread wear indicators. Worn tires must
be replaced. Different figures may apply in other countries.:::::,&.
Tire pressure
Incorrect tire pressure causes premature wear and can cause
sudden tire blow-out. For this reason, tire pressure must be checked
at least once a month .:::::,
page 249.
Driving style
Driving fast around curves, heavy acceleration and hard braking
increase tire wear.
Rotating tires 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 rotated according to the
tire manufacturer's suggested tire rotation intervals. Please
remember the following:
• Tire rotation intervals may differ from the vehicle service inter
vals outlined in your Warranty
& Maintenance Booklet.
• The longer one tire is used in one location on the vehicle, the
more it wears at certain points; therefore, we recommend that you
follow the tire manufacturer 's suggested tire rotation intervals.
• Vehicles with front-wheel drive experience more tread wear on
the front wheels compared to all-wheel drive (quattro®l .
• Please rotate tires as shown .:::::, fig. 176.
• Extra care must be taken when rotating direction -specific tires
:::::, page 277.
Wheel balancing
The wheels on new vehicles are balanced. However, various situa
tions during everyday driving can cause them to become unbal
anced, resulting in vibrations you can usually feel through the
steering wheel.
Unbalanced wheels must be rebalanced to avoid excessive wear on
steering, suspension and tires. A wheel must also be rebalanced
when a new tire is installed. _,,

Maintenance
General
Your vehicle has been designed to help keep maintenance require
ments to a minimum.
However, a certain amount of regular maintenance is still necessary
to assure your vehicle's safety, economy and reliability.
For detailed vehicle maintenance consult your Warranty
& Mainte
nance booklet.
Under difficult operating conditions, for example at extremely low
outside temperatures, in very dusty regions, when towing a trailer
very frequently, etc., some service work should be performed
between the intervals specified. This applies particularly to:
• oil changes, and
• cleaning or replacing the air filter.
ci> For the sake of the environment
By regularly maintaining your vehicle, you help make sure that emis
sion standards are maintained, thus minimizing adverse effects on
the environment. •
Important considerations for you and your
vehicle
The increasing use of electronics, sophisticated fuel injection and
emission control systems, and the generally increasing technical
complexity of today's automobiles, have steadily reduced the scope
of maintenance and repairs which can be carried out by vehicle
owners.
Also, safety and environmental concerns place very strict
limits on the nature of repairs and adjustments to engine and trans
mission parts which an owner can perform.
Controls and equip
ment Safety first Vehicle operation
Maintenance, adjustments and repairs usually require special tools,
testing devices and other equipment available to specially trained
workshop personnel in order to assure proper performance, reli ability and safety of the vehicle and its many systems.
Improper 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 tenance schedule may be a condition for upholding a possible
warranty claim made within the warranty period.
Above all, operational safety can be adversely affected, creating unnecessary 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 qualified workshop. We
strongly urge you to give your authorized Audi dealer the opportu
nity to perform all scheduled maintenance and necessary repairs.
Your dealer has the facilities, original parts and trained specialists
to keep your vehicle running properly .
Performing limited maintenance yourself
The following pages describe a limited number of procedures which
can be performed on your vehicle with ordinary tools, should the
need arise and trained personnel be unavailable. Before performing
any of these procedures, always thoroughly read all of the appli
cable text and carefully follow the instructions given. Always rigor
ously observe the
WARNINGS provided.
Before you check anything in the engine compartment, always read
and heed all WARNINGS=>
& and=> & in "Working in the engine
compartment" on
page 224.
& WARNING
• Serious personal injury may occur as a result of improperly
performed maintenance, adjustments or repairs.
