reliability. For detailed vehicle maintenance consult your Warranty &
Maintenance 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 shou ld be performed
between the intervals specified. This app lies particularly 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 standards are maintained, thus minimizing adverse effects on
the environment. •
Important considerations for you and your
vehicle
T he increasing use of electronics, sophisticated fuel injection and
em ission control systems, and the generally increasing technical
complexity of today's automobiles, have steadily reduced the scope
of mai ntenance and repai rs 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.
Maintenance, adjustments and repairs usually require special tools,
testing devices and other equipment available to spec ially 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 oper­
ation and reliability of your vehicle and even void you r vehicle
warranty . Therefore, proof of servicing in accordance with the ma in­
tenance schedule may be a condition for upholding a possible
warranty claim made w ith in the warranty period . Above all, operat
ional safety can be adversely affected, creating
unnecessary r isks for you and you r passengers.
If in doubt about any serv ic ing, have it done by your authorized Audi
dealer or any other properly equipped and qualified workshop. We
st rongly urge you to give your authorized Audi dealer the opportunity
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 ord inary tools, should the need
arise and trained personne l be unavailable. Before performing any of
these procedures, always thoroughly read all of the applicable text
and carefully follow the instructions given. Always rigorously observe
the
WARNINGS prov ided .
Before you check anything in the engine compartment, always read
and heed all WARNINGS ~
& and~ & in "Working in the engine
compartment" on
page 280.
& WARNING
• Serious personal injury may occur as a result of improperly
performed maintenance, adjustments or repairs.
• Always be extremely careful when working on the vehicle.
Always follow commonly accepted safety practices and general
common sense. Never risk personal injury.
• Do not attempt any of the maintenance, checks or repairs
described on the following pages if you are not fully familiar with
the se or other procedures with respect to the vehicle, or are uncer­
tain how to proceed.

Have the necessary work done by your authorized Audi dealer or
