---------------------------------------------
& WARNING
Improper use of run-flat tires can cause vehicle damage that can
lead to loss of vehicle control, a crash and serious personal injury.
• Run-flat tires can only be used with special rims.
• Run -flat tires must always be monitored with a properly
programmed Tire Pressure Monitoring System.
• Always inspect a tire that has lost air to make sure it is safe to
drive with the tire in the run-flat mode .
• Never drive with run-flat tires that have been damaged in a
collision.
• Never drive with run-flat tires if heat build-up causes the tire to
give off smoke.
• Never drive with run-flat tires if the vehicle shakes or vibrates
severely.
• Never drive with a run-flat tire that develops sidewall cracks or
other damage while in use.
0 Note
Run -flat tires have special characteristics and requirements, that are
very different from conventional tires . Run-flat tires require special
rims for run -flat use and cannot be used on conventional wheel
rims .
[ i] Tips
• If you are not able to continue driving with run-flat tires, please
seek professional assistance.
• Please contact your authorized Audi dealer or Audi of America,
Inc. if you have questions about tires and rims. •

Driving with run-flat tires
Handling characteristics change when tire pressure is
low.
Driving on tires with low tire pressure changes the way a
vehicle handles, particularl y when cornering and braking.
The handling characteristics of run-flat tires do not seem to
change a lot even when driving on low pressure or in the
run -flat mode . Nevertheless you must still take special
precautions when operating a vehicle on run-flat tires when
tire pressure is low o r the tire(s) is flat:
- The Electronic Stabilization Program (ESP) must be
switched on.
- Never drive faster than 50 mph (80 km/h)~ &.
- Plan ahead when driving and anticipate what you will
have to do considering traffic and road conditions up
ahead.
- Accelerate carefully.
- Avo id unnecessary and sudden steering and braking
maneuvers .
- Reduce your speed in plenty of time before intersections,
curves and other places where you may have to react
quickly.

even with run-flat tires?" ..,_

Handling characteristi cs change wh en dri ving with
low air pressure or with flat tires even with special run ­
flat tires
A low pressure or flat front tire affects vehicle hand lin g charac te ri s­
t ics by pulling the vehic le slightly to the side where the tire is
mounted and reduces brak ing performance .
A low pressure or flat
rear tire also affec ts driving c haracteristics by
pul ling to the side where th e tire is mounted and also reduces
b raki ng per for mance . T he ef fec t o n ve hic le han dlin g is most n otice ­
able when driving around curves .
& WARNING
Changed vehicle handling characteristics when driv ing in the run­
flat mode can cause lo ss of vehicle control , a crash and serious
personal injury .
• Driving on special run-flat tires in the run -flat mode will change
vehicle handling characterist ics during braki ng , when cornering
and under heavy acceleration .
• Never drive faster than the max imum rated speed of 50 mph
(80 km /h) when driving in the run -flat mode .
• Always adjust vehicle speed to traffic , road and weather condi­
tions and drive slower than the maximum rated speed if nece ssary
weather and road conditions are taken into ac count .
• Always obey speed limits and other traffic laws .
0 Note
We always recommend driv ing with even more care when using
these special tires in the run -flat mode. A lways avoid sudden
m aneuvers. •

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.

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 .,_

Controls and equip­ ment Safety first Vehicle operation
& W
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.
