Automatic car wash
The vehicle can be washed in almost any modern auto­
matic car wash.
Th e vehicle paint is so durable that the vehicle can normally be
washed without problems in an automatic car wash . However, the
effect on the paint depends to a lar ge exten t on the design of the
facility, the filtering of the wash water, the type of wash and care material, etc. If the paint has a dull appearance after going through
the car wash or is scratched, bring this to the attention of the oper­
ator immediately . If necessary, use a different car wash.
The power top does not require special precautions before passing
through a car wash .
However, the car must not be treated with hot
wax after the wash cycle!
The wax could adverse ly affect the power
top and even damage the fabr ic over a period of time .
The power top does not have to be washed every time you use a car
wash. The power top can be spared if the car wash facility is equ ipped
with manually adjustable roof brushes or rollers.
Before going thro ugh a car wash, be sure to take the usual precau­
tions such as closing the windows . Remove antenna if applicable.
If you have installed additional accessories on the vehicle -such as
spoilers, etc. -it is best to ask the car wash operator if these should
be removed.

Changing the engine oil
The engine oil and oil filter must be changed according to the mileage
(kilometers) and time intervals specified in your vehicle's Warranty
&
Maintenance booklet. Do not exceed these intervals -harmful
deposits from old engine oil can reduce engine performance and can
lead to expensive engine repairs.
Changing the oil at the recommended intervals is so very important
because the lubricating properties of oil decrease gradually during
normal vehicle use. If you are not sure when you have your oil
changed, ask your authorized Audi Service Advisor .
Under some circumstances the engine oil should even be changed
more frequently. Change oil more often if you drive mostly short
distances, operate the vehicle in dusty areas or mostly under stop­
and-go traffic conditions, or when you use your vehicle where temper­
atures stay below freezing point for long periods.
Detergent additives in the oil will make fresh oil look dark after the
engine has been running for a short time. This is normal and is not a
reason to change the oil more often than recommended.
Damage or malfunctions due to lack of maintenance
It is essential that you change your oil at the recommended intervals
using only engine oil that complies with Audi oil standard
VW
502 00 . Your Limited New Vehicle Warranty does not cover
damage or malfunctions due to failure to follow recommended main­
tenance and use requirements as set forth in the Audi Owner's
Manual and Warranty
& Maintenance booklet. Your dealer will have
to deny warranty coverage unless you present to the dealer proof in
the form of Service or Repair Orders that all scheduled maintenance
was performed in a timely manner. •
Safety first
Engine oil consumption
The engine in your vehicle depends on an adequate
amount of oil to lubricate and cool all of its moving parts.
In order to provide effective lubrication and cooling of internal
engine components, all internal combustion engines consume a
certain amount of oil. Oil consumption varies from engine to engine
and may change significantly over the life of the engine. Typically,
engines with a specified break-in period (see~
page 250) consume
more oil during the break-in period than they consume after oil
consumption has stabilized.
Under normal conditions, the rate of oil consumption depends on the
quality and viscosity of the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient temperature and road
conditions. Further factors are the amount of oil dilution from water
condensation or fuel residue and the oxidation level of the oil. As any
engine is subject to wear as mileage builds up, the oil consumption
may increase over time until replacement of worn components may
become necessary.
With all these variables coming into play, no standard rate of oil
consumption can be established or specified. There is no alternative
to regular and frequent checking of the oil level, see
Note.
If the yellow engine oil level warning symbol in the instrument
cluster _ lights up, you should check the oil level as soon as possible
~ page 284. Top off the oil at your earliest convenience~ page 285.
& WARNING
Before you check anything in the engine compartment, always
read and heed all WARNINGS~
& in "Working in the engine
compartment" on page
280.

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.
• Do not do any work without the proper tools and equipment.
Have the necessary work done by your authorized Audi dealer or
another properly equipped and qualified workshop .
