216 Tires and wheels
Run-flat tires have special characteristics
and requirements, that are very different
from conventiona l tires. Run-flat tires re­
quire special rims for run-flat use and can­
not be used on conventional wheel rims.
(D Tips
- If you are not able to continue driving
with run-flat tires, please seek professio­
nal assistance .
- Please contact your authorized Audi
dealer or Audi of America, Inc. if you
have questions about tires and r ims.
Driving with run-flat tires
App lies to vehicles: 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, particularly when
cornering and braking . The handling charac­
teristics of run-flat tires do not seem to
change a lot even when dr iving on low pres­
sure or in the run-flat mode . Nevertheless you
must still take special precautions when oper­
ating a vehicle on run-flat tires when tire pres­
sure is low or the tire(s) is fla t:
"'The Electronic Stabilization Program (ESP)
must be switched on.
> Never drive faste r 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.
"' Avoid unnecessary and sudden steer ing and
braking maneuvers .
"' Reduce your speed in plenty of time before
i ntersections, curves and other places where
you may have to react quickly.
Please see:
¢ page 215, When it is not possi­
ble to continue driving, even with run-flat
tires?
Handling characteristics change when
driving with low air pressure or with flat
tires even with special run-flat tires
A low pressure or flat front tire affects vehicle
handling characterist ics by pulling the vehicle
slightly to the side whe re the tire is mounted
and reduces braking performance .
A low pressure or flat
rear tire also affects
driving characteristics by pulling to the s ide
where the tire is mounted and also reduces
braking performance . The effect on vehicle
handling is most noticeable when driving
aro und curves .
A WARNING
Changed vehicle hand ling characteristics
when driving in the run-flat mode can
cause loss of vehicle control, a crash and
serious personal injury.
- Driving on special run-flat tires in the
run-flat mode will change vehicle han­
dling characterist ics dur ing braking,
when cornering and under heavy acceler­
ation .
- 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 traff ic,
road and weather conditions and drive
slower than the maximum rated speed if
necessary weathe r and road cond it ion s
are taken into account.
- Always obey speed limits and other traf­
f ic laws.
(D Note
We always recommend driving with even
more care when using these special tires in
the run-flat mode. Always avoid sudden
maneuve rs.

' General
Your vehicle has been designed to help keep
maintenance requirements 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 Warranty& Maintenance booklet.
Under difficult operating conditions , for ex­
ample at extremely low outside temperatures,
in very dusty regions, etc., some service work
shou ld be pe rformed between the intervals
specified. This applies particularly to:
- oil changes, and
- cleaning or replacing the air fi lter.
@ For the sake of the environment
By regu larly maintaining your vehicle, you
help make sure that emission standards
are maintained, thus min imizing adverse
effects on the environment.

Als o, sa fe ty a nd en vir onm ent al con­
cerns p lace very strict limits on the nature of
repairs and adjustments to engine and trans­
miss ion parts which an owner can perform .
Maintenance, adjustments and repa irs usua lly
require special tools, testing dev ices and oth­
er equipment available to specially trained
workshop personnel in order to assure proper pe rformance, reliab ility and safety of the vehi­
cle and its many systems .
Improper maintenance, adjustments and re­ pa irs can impair the operation and reliab ility
of your vehicle and even void your vehicle war­
ranty. Therefore , proof of servic ing in accord­
ance w ith the ma intenance schedule may be a
condition for upholding a poss ible warranty
claim made within the warranty period.
Above all, operational safety can be adversely
affected, c reating unnecessary risks for you
and your passengers .
If in doubt about any se rv icing, have it done
by your author ized Audi dealer or any other
p roperly equipped and qualified workshop .
We strong ly urge you to give yo ur a utho rized

_& WARNING
- Ser ious personal injury may occur as a re­
sult of improperly performed mainte­
nance, adjustments or repa irs .
- Always be extremely careful when work­
ing on the vehicle . Always follow com­
monly accepted safety pract ices and gen­
eral common sense. Never r is k personal
inju ry.
- Do not attempt any of the maintenance ,
checks or repairs descr ibed on the fol­
lowing pages if you are not fu lly fam iliar
with these or other procedures with re ­
spect to the vehicle, or are uncertain how
to proceed .
- Do not do any work without the proper
too ls and equipment. Have the necessa ry
work done by your author ized A udi deal­
er or another proper ly equipped and
qualified workshop.
- The engine compartment of any motor
veh icle is a potentially hazardous area.
Never reach into the area around or
touch the radiator fan. It is temperature controlled and can sw itch on suddenly -
even when the engine is off and the igni­
tion key has been removed. The rad iator
fan switches on automa tical ly when the
coo lant reaches a certain temperature
and will continue to run until the coo lant
temperature drops .
- Always remove the ign ition key before
anyone gets under the vehicle.
- Always support your veh icle with safety
stands if it is necessary to work under­
neath the vehicle. The jack supplied with
the vehicle is not adequate for this pur­ pose and cou ld 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 leve l ground,
that the wheels a re a lways secure ly
b locked and that the engine cannot be
started.

Technical Modifications
Our guidelines must be complied with when technical modifications are made .
Always consult an authorized Audi dealer be­
fore starting work on any modifications.
This will help ensure that vehicle function,
performance and safety are not impaired
¢ &. .
Attempting to work on electronic components
and the software used with them can cause
malfunctions. Because of the way electronic
components are interconnected with each
other, such malfunctions can also have an ad­
verse affect on other systems that are not di­
rectly involved. This means that you risk both
a substantial reduction in the operational
safety of your vehicle and an increased wear of
ve hicle parts ¢
A:,..
Author ized Audi dealers will perform th is
wo rk in a professiona l and competent manner
or, in special cases, refer you to a professional
company that specializes in such modifica­
tions .
A WARNING
Improper repairs and modifications can
change the way vehicle systems work and
cause damage to the veh icle and serious
personal injury.
If emergency repairs must be performed
elsewhere, have the vehicle examined by
an authorized Audi dealership as soon as
possible.
