& WARNING
Improperly tightened or maintained wheel bolts can become loose
causing loss of control, a collision and serious personal injury .
• Always keep the wheel bolts and the threads in the wheel hubs
clean so the wheel bolts can turn easily and be properly tightened .
• Never grease or oil the wheel bolts and the threads in the wheel
hubs. They can become loose while driving if greased or oiled,
even if tightened to the specified torque.
• Only use wheel bolts that belong to the rim be ing installed.
• Never use different wheels bolts on your vehicle.
• Always maintain the correct tightening torque for the wheel
bolts to reduce the risk of a wheel loss .
If the tightening torque of
the wheel bolts is too low , they can loosen and come out when the
vehicle is moving. If the tightening torque is too high, the wheel
bolts and threads can be damaged and the wheel can become
loose .
0 Note
The specified torq ue for the wheel bolts is 9 0 ft lb (120 Nm) with a
t o lerance of± 7,4 f t lb (± 10 N m). To rque w hee l bo lt s d ia g ona lly .
After chang ing a wheel, the torque must be checked as soon as

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.

d ifferent from th e tir es on y our v ehic le .
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 .

reverse order to that described in=> page 280,
"Connecting/disconnecting the jumper cable.". When
doing so, make sure that the cable cannot contact
rotating engine parts.
14. Close the cover on the posit ive terminal.
The battery is vented to the outside to prevent gases from entering
the vehicle interior. Make sure that the jumper clamps are well
connected with their
metal parts in full contact with the battery
terminals.
& WARNING
To avoid serious personal injury and damage to the vehicle, heed
all warnings and instructions of the jumper cable manufacturer.
If
in doubt, call for road service .
• Jumper cables must be long enough so that the vehicles do not
touch.
• When connecting jumper cables, make sure that they cannot
get caught in any moving parts in the engine compartment.

& 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. •
