reliability. For detailed vehicle maintenance consult your Warranty &
Maintenance book let.
Und er di ffi cult ope rating cond ition s, for example at extremely low
outside temperatures, in very dusty regions, etc ., some service work
should be performed between the intervals specified. This app lies
particularly to:
• oil changes, and
• cleaning or replacing the air filter.
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 general ly increasing technical
complexity of today's automobi les, have steadi ly reduced the scope
of maintenance and repa irs which can be carried out by vehicle
owners.
Al so, sa fety a nd e nvironment al concerns p lace very strict
limi ts on the na ture of repairs a nd adjustments to engine and trans ­
mission parts which an owner can perform.
Maintenance, adjustments and repairs usually require special tools,
testing dev ices and other equipment ava ilable to specially trained
workshop personnel in order to assure proper performance, reli ­
abil ity and safety of the vehicle and its many systems.
Improper maintenance, adjustments and repairs can impair the
ope ration and re liability of your vehic le and even void your vehic le
warranty. Therefore, proof of servicing in accordance with the main­
tenance schedu le may be a condition for upholding a pos sible
warranty claim made within the warranty period. Above all, operational safety can be adversely affected, creating
unnecessary r isks for you and your passengers .
If in doubt about any servicing, have it done by your authorized Audi
dea ler 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 fac ilities, origina l parts and trained spec ial ists
to keep your vehicle running proper ly.

can be performed on your vehicle wi th ordinary too ls, should the
need arise and trained personnel be unavai lab le. Before performing
any of these procedures, a lways thoroughly read all of the appli ­
cable text and carefu lly follow the instructions given. Always rigor ­
