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.

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, 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.
~ 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

Vehicle operation
& WARNING (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) and the park br ake is firmly
appl ied .
