& 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 jock first before the
wheel con be removed.

proper positioning of
lifting jack
- Position the jack below the door sill under the mounting
point
that is closest to the wheel to be changed
~ fig. 219.
- Turn the
jack handle clockwise until the jack arm just fits
underneath the rib running along the underbody
~ &,.
- Align the jack so that the jack arm claw~ fig. 220 @fits
snugly around the underbody rib and the movable base
plate ® sits flat on the ground.
- Wind the jack up further until the flat wheel comes off the
ground~ &-
Recesses at the front and rear of the underbody rib mark the proper
mounting locations for the jack => fig. 219. There is only one desig­
nated 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. •

- Then completely unscrew the other wheel bolts as
described above .
- Take off the wheel leaving the alignment p in in the bolt
hole.
Puttin g on th e sp are
- Lift the spare wheel up and carefu lly s lide it over the
alignment pin to gu ide it in place .
- Use t he hexagonal socket in the screwd river handle to
screw in and tighten all w heel bolts
slightly.
- Unscrew the alignment pin and insert and tighten the
remaining w heel bolt slightly like the rest.
- Turn the handle on the jack counter-clockwise to lower
the vehicle until the jack is fully released.
- Use the wheel bo lt wrench to tighten all wheel bo lts
firmly=>
page 295. Tighten crosswise, from one bolt to
the (approx imately) oppos ite one, to keep the wheel
centered.
[ i ] Tip s
Never try and use the hexagona l socket in the handle of the screw­
driver to loosen or tighten the wheel bolts.
• Pull the reversible b lade from the screwdriver before you use the
hexagonal socket in the handle to turn the wheel bo lts.
• When mounting tires with
uni dire cti on al tread desig n make sure
the tread pattern is pointed the right way~
page 298.
• The whee l bolts should be clean and easy to turn. Check for dirt
and corrosion on the ma ting surfaces of both the wheel and the
hub. Remove all dirt from these surfaces before remounting the
wheel. •
Tires with unidirectional tread design
Tires with unidirectional tread design must be mounted
with their tread pattern pointed the right direction.
U sin g a spa re tire wit h a tre ad p atte rn int ended for u se
i n a sp ec ific dir ection
When using a spare tire with a tread pattern intended for use in a
specific direction, please note the following:
• The direction of rotation is marked by an arrow on the side of the
tire.
• If the spare tire has to be installed in the incorrect direction in the
event of a flat tire, use the spare tire on ly temporarily since the tire
will not be able to achieve its optimum performance characteristics
with regard to aquaplaning, noise and wear.
• We recommend that particular attention be paid to this fact
dur ing wet weather and that you adjust your speed to match road
conditions.
• Replace the flat tire with a new one and have it instal led on your
vehic le as soon as possible to restore the handling advantages of a
proper ly pointed direction-dependent tire. •
Notes on wheel change
Please read the information~ page 279, "New tires and replacing
tires and whee ls", if you are going to use a spare tire which is
different from the tires on your veh ic le.
After you change a tire: .,_

_____________________________________________ W_ h _a_t _ d_ o_ l _d _o _ n_o_ w_ ?_ . _ .... I'll
•
• Check the tire pressure on the spare immediately after
mounting.
• Have the wheel bolt t ightening torque checked with a torque
wrench as soon a s possible by your authorized Audi dealer or a
qualified se rvice station .
• On steel and alloy wheel rims , the wheel bolts are correctly tight­
ened with a torque of 90
ft lb 1120 Nm ).
• If you notice while changing a tire that the wheel bolts are
corroded and diffi cult to turn while changing a tire , 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 r ims which
differ from those which were factory installed , then be sure to read
the information
~ page 279 , "New tires and replacing tires and
wheels ".
• Always make sure the damaged wheel or even a flat tire and
the jack and tool kit are properly secured in the luggage compart ­
ment and are not loose in the passenger compartment .
• In an accident or sudden maneuver they could fly forward ,
injur ing anyone in the vehicle .
• Always store damaged wheel , jack and tools securely in
luggage compartment . Otherwise , in an accident or sudden
maneuver they could fly forward, causing injury to passengers in
the vehicle .

& WARN ING (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 sw itch 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
vehi cle .
• Always support your vehicle with safety stands if it is neces ­
sary to work underneath the vehicle . The jack suppl ied 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 veh icle is on level ground , that
the wheels are always securely blocked and that the engine
cannot be sta rted .
• Always make sure the transmission selector lever (automatic
transmission) is in "P " (Park position ) or Neutral (manual transm is­
sion) and the park brake is firmly applied.
W For the sake of the environment
• Cha ng ing t he e ngine sett ings will adverse ly aff ect em iss ion
