rear a xle or the body side members. This could lead to serious
damage.
- To avoid damage to the underbody or chassis frame , a rubber
pad must be inserted between the floor jack and the lift points .
- Before dr iving over a workshop hoist , check that the vehicle
weight does not exceed the permis sible lifting capacity of the
hoist .
- Before driving over a workshop hoist , en sure that there i s
sufficient clearance between the hoist and low parts of the
vehicle. •

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 .

& WARN ING (continued )
• The engine compartment of any motor vehicle is a potentially
hazardous area . Never reach into the area around or touch the
radiator fan . It is temperature controlled and can sw itch on
suddenly -even when the engine is off and the ignition key has
been removed . The radiator fan switches on automatically when
the coolant reaches a certain temperature and will continue to run until the coolant temperature drops .
• Always remove the ignition key before anyone gets under the
vehi cle .
• Always support your vehicle with safety stands if it is neces ­
sary to work underneath the vehicle . The jack suppl ied with the
vehicle is not adequate for this purpose and could collapse causing serious personal injury .
• If you must work underneath the vehicle with the wheels on
the ground, always make sure the veh icle is on level ground , that
the wheels are always securely blocked and that the engine
cannot be sta rted .
• Always make sure the transmission selector lever (automatic
transmission) is in "P " (Park position ) or Neutral (manual transm is­
sion) and the park brake is firmly applied.

A lways consult an authorized Audi dealer before starting work on
any modifications .
This w ill help ensure that vehic le function, performance and safety
are not impaired=> &-
Attempting to work on electronic components and the software used with them can cause malfunctions. Because of the way elec ­
tronic components are interconnected with each other, such
malfunctions can also have an adverse affect on other systems that
are not directly involved . This means that you risk both a substantial
reduct ion in the operat ional safety of your vehicle and an increased
wear of vehicle parts=>&.
