Weights
Gross Vehicle Weight Rating
The Gross Vehicle Weight Rating (GVWR), and the Gross Axle Weight
Rating (GAWR) for front and rear are listed on a sticker on the left
door jamb.
Controls and equip­ ment Safety first Vehicle operation
The
Gross Vehicle Weight Rating includes the weight of the basic
vehicle plus full fuel tank, oil and coolant, plus maximum load,
which includes passenger weight (150 lbs/68 kg per designated
seating position) and luggage weight.
Gross Axle Weight Rating
The Gross Axle Weight Rating is the maximum load that can be
applied at each axle of the vehicle~&.
Vehicle capacity weight
The vehicle capacity weight (max. load) is listed either on the
driver's side 8 -pillar or inside the fuel filler flap.
& WARNING
• The actual Gross Axle Weight Rating at the front and rear axles
should not exceed the permissible weights, and their combination
must not exceed the Gross Vehicle Weight Rating.
• Exceeding permissible weight ratings can result in vehicle
damage, accidents and personal injury.
0 Note
• The vehicle capacity weight figures apply when the load is
distributed evenly in the vehicle (passengers and luggage). When
transporting a heavy load in the luggage compartment, carry the
load as near to the rear axle as possible so that the vehicle's
handling is not impaired.
• Do not exceed the maximum permissible axle loads or the
maximum gross vehicle weight. Always remember that the vehicle's
handling will be affected by the extra load. Therefore, adjust your
speed accordingly.
• Always observe local regulations. •

Operating your vehicle outside the
U.S.A. or Canada
Governmen t regulations in the Un ited States and Canada require
that automobiles meet specific emission regu lations and safety .,_

standards. Therefore, vehicles built for the U.S .A. and Canada differ
from vehicles sold in other countries.
If you plan to take your vehicle outside the continental limits of the
United States or Canada, there is the possibility that
• unleaded fuels for vehicles with catalytic converter may not be
available;
• fuel may have a considerably lower octane rating. Improper fuel
may cause engine damage;
• service may be inadequate due to lack of proper service facilities,
tools or testing equipment;
• replacement parts may not be readily available .
• Navigation systems for vehicles built for the U.S.A. and Canada
will not necessarily work in Europe , and may not work in other coun­
tries outside of North America.

Audi cannot be responsible for mechanical damage that could
result from inadequate fuel , service or parts availability .•

Maintenance
General
Your vehicle has been designed to help keep maintenance require­
ments to a minimum. However, a certain amount of regular mainte­
nance is still necessary to assure your vehicle 's safety, economy and
reliability. For detailed vehicle maintenance consult your Mainte­
nance & Warranty booklet .
Under difficult operating conditions, for example at extremely low
outside temperatures, in very dusty regions, etc., some service work
should be performed between the intervals specified . This applies
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
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.
Maintenance, adjustments and repairs usually require special tools,
testing devices and other equipment available to specially trained .,_

abil ity and sa fe ty of the vehicle a nd i ts many sys te m s.
I mproper maintenance, adjustments and repairs can impair the
operation and reliabil ity of your vehicle and even void your vehicle
war ra nty. T here fore, proof o f serv ic ing in accorda nce with the main ­
tenance schedule may be a condition for uphold ing a possible
war ra nty claim made withi n th e warranty per iod .
Above all, operat ional safety can be adverse ly affected, creating
unnece ssary risks fo r you and you r passengers .
If in doubt about a ny servici ng, have it do ne by your authorized Aud i
dea ler or any other properly equipped and qua lified workshop. We
str ongly u rge you to give your auth orized Audi dealer the oppo rtu ­
nity to perform al l scheduled maintenance and necessary repairs.

to keep your vehic le running proper ly.
Performing limited maintenance yourself
T he fo llow ing pages describe a limited numbe r of procedures which
can be perfo rme d on you r vehicle wi th ordi nary too ls, should the
need arise and trained personne l be unavailab le. Before performing
any of these proced ures, always thor oug hly read a ll of th e appli­
cable text and carefu lly fo llow the instructions given. Always rigor ­
ously observe the
WARNINGS provided .
Before you check anything in the engine compartment , alway s read
and heed all WARNINGS:::>

page 220.
& WARNING
• Ser ious persona l injury may occur as a result of improperly
performed maintenance , adjustments or repairs.
• Always be e xtremely careful when working on the vehicle .

ARNING (continued )
• Do not attempt any of the maintenance , checks or repairs
described on the following pages if you are not fully familiar with
these or other pro cedures 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 autho rized Audi dealer or
another properly equipped and qualified workshop .
• The engine compartment of any motor vehicle is a potentially
hazardous area . Never reach into the area around or touch the
radiator fan . It i s temperature controlled and can switch on
suddenly -even when the engine is off and the ignition key has
been removed . The radiator fan switche s on automatically when
the coolant reaches a certain tempe rature and will continue to run
until the coolant temperature drops .
• Always remove the ignition key before anyone gets under the
vehicle.
• Always support your vehicle with safety stands if it is neces­
sary to work underneath the vehicle. The jack supplied 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 vehicle is on level ground , that
the wheels are always securely blocked and that the engine
cannot be started .
• Always make sure the transmission selector lever (automatic
transmission) is in "P" (Park position ) (automatic transmission ) or
Neutral (manual tr ansm ission) and the hand brake is firmly
applied.
• Chang ing t he e ngine sett ings wi ll a dverse ly affect em ission
levels. This is detrimenta l to the environment and increases fuel
co nsu mp tion.

Technical Modifications
Our guidelines must be c omplied with when technical
modifications are made.
A lways consult an authorized Audi dealer before starting work on
any modifications.
T his will he lp ensure that vehicle function, performance and safety
are no t impaired =>& .
Attempting to work on electronic components and the software used with them can cause malfunctions . Because of the way elec ­
t ronic components are interconnected w ith each other , such
malfunctions can also have an adverse affect on other systems that
are not directly involved. Th is means that yo u risk both a substantial
reduction in the operational safety of your vehicle and an increased
wear of vehicle parts=>& .
Authorized Audi dealers will perform this work in a professional and competent manne r or , in specia l cases, refer you to a pr ofessiona l
company t hat special izes in suc h modificat ions.
