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

Loosening and tightening the wheel bolts
The wheel bolts must be loosened before raising the
vehicle.

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.

What do I do now? -
------------------
Fig. 165 Close-up:
proper positioning of
lifting jack
- 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.
0 Note
A floor jack or the pads on the hoist arms must not be positioned at
the points shown

After you ch ange a tire :
• Check the tire pressure on the spare immediately after
mounting.
• Have the wheel bolt tightening torque checked with a torque
wrench as soon as possible by your authorized Audi dealer or a qualified service station .
• With steel and alloy wheel rims, the wheel bolts are correctly
tightened at a torque of 90 ft lb (120 Nm l.
• If you notice while changing a tire that the wheel bolts are
corroded and difficult to turn , then they should be replaced before
you check the tightening torque.
• Replace the flat tire with a new one and have it installed on your
vehicle as soon as possible . Remount the wheel cover.
Until then , drive with extra care and at reduced speeds .
& WARNING
• If you are going to equip your vehicle with tires or rims which
differ from those which were factory installed , then be sure to read
the information
=> page 246, "New tires and replacing tires and
wheels ".
• Always store the tools securely in luggage compartment .
Otherwise, in an accident or sudden maneuver they could fly
forward, causing injury to passengers in the vehicle.

& WARNING (continued)
• The engine compartment of any motor vehicle is a potentially
hazardous area. Never reach into the area around or touch the
radiator fan. It is temperature controlled and can switch on
suddenly -even when the engine is off and the ignition key has
been removed. The radiator fan switches on automatically when
the coolant reaches a certain temperature 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 transmission) and the hand brake is firmly
applied.
<£> For the sake of the environment
• Changing the engine settings will adversely affect emission
levels. This is detrimental to the environment and increases fuel
consumption .
• Always observe environmental regulations when disposing of
old engine oil, used brake fluid, dirty engine coolant, spent batteries
or worn out tires.
• Undeployed airbag modules and pretensioners might be classi ­
fied as Perchlorate Material -special handling may apply, see
www.dtsc.ca.gov/hazardouswaste/perchlorate . When the vehicle or
parts of the restraint system including airbag modules safety belts
Controls and equip­ ment Safety first Vehicle operation with pretensioners are scrapped, all applicable laws and regula­
tions must be observed. Your authorized Audi dealer is familiar with
these requirements and we recommend that you have your dealer
perform this service for you. •
