Lifting the vehicle
Important safety precautions
Be aware of the following hazards before lifting the vehicle with a
workshop hoist or floor jack:
• The vehicle should never be lifted or jacked up from underneath
the engine oil pan, the transmission housing, the front or rear axle
or the body side members. This could lead to serious damage.
• Use lifting equipment with padded contact surfaces to avoid
damage to the underbody or chassis frame.
• Alternatively, cover the contact surfaces on workshop hoist or
floor jack with rubber pads before lifting .
• Before driving over a workshop hoist, check that the vehicle
weight does not exceed the permissible lifting capacity of the hoist .
• Before driving over a workshop hoist, ensure that there is suffi ­
cient clearance between the hoist and low parts of the vehicle .
& WARNING
To reduce the risk of serious injury and vehicle damage:
• Always lift the vehicle only at the special workshop hoist and
floor jack lift points illustrated
=> fig. 202 and => fig. 203 .
• Failure to lift the vehicle at these points could cause the vehicle
to tilt or fall from a lift if there is a change in vehicle weight distri­
bution and balance. This might happen, for example, when heavy
components such as the engine block or transmission are
removed .
• When removing such heavy components, anchor vehicle to
hoist or add corresponding weights to maintain the center of
gravity . Otherwise , the vehicle might tilt or slip off the hoist,
causing serious personal injury. •
Lifting with workshop hoist and with floor
jack
The vehicle may only be lifted at the lifting points illus­
trated.

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.
