& WARNING (continued)
• 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 specia l 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
• I f 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. •
Applies to vehic les: with Run-flat t ires
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, particularly 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 or 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.
- Avoid 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.
Please see:=> page 258, "When it is not possible 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 characteris ­
tics by pulling the vehicle slightly to the side where the tire is
mounted and reduces braking performance.
A low pressure or flat rear tire also affects driving characteristics by
pulling to the side where the tire is mounted and also reduces
braking performance. The effect on vehicle handling is most notice ­
able when driving around curves.
& WARNING
Changed vehicle handling characteristics when driving in the run­
flat mode can cause loss of vehicle control, a crash and serious personal injury. .,,,

& WARNING (continued)
• Driving on special run-flat tires in the run-flat mode will change
vehicle handling characteristics during braking, when cornering
and under heavy acceleration .
• Never drive faster than the maximum rated speed of 50 mph
180 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 necessary
weather and road conditions are taken into account .
• Always obey speed limits and other traffic laws.
0 Note
We always recommend driving with even more care when using
these special tires in the run-flat mode. Always avoid sudden
maneuvers. •

Replacing run -flat tires and rims
Your vehicle was especially designed to use special run­
flat tires.
You may use and combine only approved run-flat tires and special
matching rims that have been designed for run-flat tires. Mounting
special run-flat tires on standard wheels will not work and will not
provide the advantages fo the run-falt feature. Never use special
run-flat tires on standard wheel rims .
After driving with a tire in the run -flat mode , always have the vehicle
and affected tire(sl and rim(s) inspected by an authorized Audi
dealer. Tires that have been driven in the run -flat mode must be
replaced.
& WARNING
Use of damaged run-flat tires and rims can cause vehicle damage
that can lead to loss of vehicle control, a crash and serious
personal injury .
• Always have the vehicle and affected tire(sl and rim(sl
inspected by an authorized Audi dealer after driving a tire in the
run-flat mode.
• Tires that have been driven in the run-flat mode must be
replaced. •

Loosening and tightening the wheel bolts
The wheel bolts must be loosened before raising the
vehicle.
Loosening
Fig . 163 Wheel
change: loosening the
wheel bolts
- Fit the wheel bolt wrench over the wheel bolt and push it
down as far as it will go .
- Close your grip around the
end of the wrench handle for
maximum torque and turn the wheel bolts
counter-clock­
wise
about one single turn in the direction of arrow
~ fig. 163.
Tightening
Fit the wheel bolt wrench over the wheel bolt and push it
down as far as it will go.
- Close your grip around the
end of the wrench handle for
maximum torque and turn each wheel bolt
clockwise
until it sits tight.
& WARNING
• Using force without control to speed the wheel change up can
cause the vehicle to slip off the jack and cause serious personal
injuries.
• Do not loosen the wheel bolts more than one turn before you
raise the vehicle with the jack. -Risk of injury!
[ i] Tips
• Never try and use the hexagonal socket in the handle of the
screwdriver to loosen or tighten the wheel bolts.
• If a wheel bolt sits very tight, you may find it easier to loosen by
carefully pushing down on the end of the wheel bolt wrench with
one foot only . As you do, hold on to the car to keep yourself stable
and take care not to slip.•
Raising the vehicle
The vehicle must be lifted with the jack first before the
wheel can be removed.

- Find the mounting point on the rocker panel which is
closest to the flat tire =>
page 270, fig. 164 -arrows-.
- Crank the jack up until it can be positioned under the lift
point on the vehicle.
- Align the jack so the claw=> fig. 165@ grips the
mounting point on the rocker panel and the flexible base
plate ® is flat on the ground.
- Continue to crank the jack until the wheel is lifted just
clear of the ground.
Recesses at the front and rear of the underbody rib mark the proper
mounting locations for the jack=>
page 270 , fig. 164. There is only
one
designated jack mounting point for each wheel. Do not apply
the jack anywhere else=>&.
The jack should be positioned approximately 6 in. (15 cm) behind
the front wheel or 10 in. (25 cm) in front of the rear wheel.
An
unstable surface under the jack can cause the vehicle to slip off
the jack. Always provide a firm base for the jack on the ground. If
necessary place a sturdy board or similar support under the jack. On
hard, slippery surfaces (such as tiles) use a rubber mat or similar to
prevent the jack from slipping=> &.
& WARNING
• You or your passengers could be injured while changing a
wheel if you do not follow safety precautions:
-Mounting the jack under the vehicle at any other place than
indicated above may damage the vehicle or may result in
personal injuries.
- A soft or unstable surface under the jack may cause the
vehicle to slip off the jack. Always provide a firm base for the
jack on the ground. If necessary, use a sturdy board under the
jack.
- On hard, slippery surface (such as tiles) use a rubber mat or
similar to prevent the jack from slipping.
• To help prevent injury to yourself and your passengers:
-Do not raise the vehicle until you are sure the jack is securely
engaged.
- Passengers must not remain in the vehicle when it is jacked
up.
- Make sure that passengers wait
in a safe place away from
the vehicle and well away from the roadway and traffic.
- Make sure jack position is correct, adjust as necessary and
then continue to raise the jack.

Fuses and bulbs -
------------------
The various electrical circuits are protected by fuses. The fuses are
clustered in a centralized unit. The unit is located behind the face
panel at the end of the instrument panel.
Two spare fuses and a sticker identifying the fuses are located on
the inside of the fuse box cover.
You are well advised to keep a supply of spare fuses in your vehicle.
Fuses with the proper ampere ratings are available at your autho­
rized Audi dealer.
& WARNING
Never replace a fuse with one that has a higher amperage rating .
• A fuse with a too high amperage could damage the electrical
part and cause a fire.
0 Note
• On no account should fuses be repaired (e.g. patched up with tin
foil or wire) as this may cause serious damage elsewhere in the elec­
trical circuit or cause fire.
• If a fuse blows repeatedly, do not keep replacing it. Instead, have
the cause for the repeated short circuit or overload tracked and
fixed. •
