Emergency assistance
After changing a wheel
A wheel change is not complete without the do­
ing the following .
• Always store the vehicle tool kit, the jack* and
the replaced tire in the luggage compartment
<=>page 135.
• Check the tire pressure on the spare wheel im­
mediate ly after mounting it.
• As soon as possible, have the
tightening tor­
ques
on all wheel bolts checked with a torque
wrench. The correct tightening torque is 90 ft
lb (120 Nm).
• Have the flat tire
replaced as soon as possible.
@ Tips
- If you notice that the whee l bolts are cor­
roded and difficu lt to turn while changing a
tire, they should be replaced before you
check the tightening torque .
- Drive at reduced speed until you have the
tightening torques checked.
- After changing a wheel, the tire pressure in
a ll four tires must be checked/corrected and
the tire pressure mon itor ing indicator must
be stored in the MMI
c> page 255.
Decorative wheel covers
App lies to: vehicles with decorative wheel covers
The decorative wheel covers must be removed
first to access the wheel bolts .
Fig. 216 Chan gin g a w heel : Removing the whee l cover
Removing
• Insert the hook (provided with the ve hicle tool
kit) in the hole in the wheel hub cover.
• Pull off the
decorative wheel cover c> fig. 216.
260
Wheels with wheel bolt caps
Applies to: vehicles with wheel bo lts with caps
The caps must be removed first from the wheel
bolts before the bolts can be unscrewed .
Fig. 217 Changing a wheel: removing the wheel bo lt caps
Removing
• Push the plastic clip (provided with the vehicle
tool kit) over the whee l bolt cap until the inner
retainers on the clip align with the edge of the
cover.
• Remove the cap with the
plastic clip (vehicle
tool kit)
<=> fig. 217 .
Refitting
• Place the caps over the wheel bolts and push
them back on .
The caps are to protect and keep the wheel bolts
clean.
Loosening and tightening the wheel bolts
The wheel bolts must be loosened before raising
the vehicle.
Fig. 218 Chang ing a wheel: loosening the wheel bo lts

Loosening
• Slide the wh eel wr ench onto the wheel bolt as
far as it will go.
• Take tight hold of the
end of the wrench handle
and turn the wheel bolts
counter-cloc kwise
about one single turn in the direction of arrow
<=>fig. 218.
Tightening
• Slide the wheel wrench onto the wheel bolt as
far as it w ill go.
• Take tight hold of the
end of the wrench handle
and turn each wheel bolt
cloc kwise until it is
seated.
A WARNING
- Do not use force or hurry when changing a
wheel· you can cause the vehicle to slip off
the jack and cause se rious personal injur ies.
- Do not loosen the wheel bolts more than
one turn
before you raise the vehicle with
the jack. -You risk an injury.
(D Tips
- Never use the hexagonal socket in the han­
dle of the screwdriver to loosen or tighten
the wheel bo lts .
- If a wheel bolt is
very tight, you may find it
easier to loosen by carefully push ing down
on the end of the wheel bo lt wrench with
one
foot only . As you do so, hold on to the
car to keep your balan ce and take care no t
to slip .

Emergency assistance
After you have loosened all wheel bolts and raised the vehicle off the ground, remove and re­
place the wheel as follows:
Removing the wheel
.,. Use the hexagonal socket in the screwdriver
handle
to completely remove the topmost
wheel bolt and set it aside on a
clean surface
.::!> fig. 223.
.,. Screw the threaded end of the alignment pin
from the tool kit hand-tight into the empty bolt
hole¢
fig. 224 1> .
.,. Then remove the other wheel bolts as described
above.
.,. Take off the wheel leaving the alignment pin in
the bolt hole ¢0 .
Putting on the spare wheel
.,. Lift the spare wheel and carefully slide it over
the alignment pin to guide it in place ¢0 .
.,. Use the hexagonal socket in the screwdriver
handle to screw in and tighten all wheel bolts
slightly .
.,. Remove the alignment pin and insert and tight­
en the remaining wheel bolt slightly like the
rest.
.,. Turn the jack handle counter-clockwise to lower
the vehicle until the jack is fully released.
.,. Use the wheel bolt wrench to tighten all wheel
bolts firmly ¢
page 260 . Tighten them cross­
wise,
from one bolt to the (approximately) op­
posite one, to keep the wheel centered.
0 Note
When removing or installing the wheel, the
rim could hit the brake rotor/ceramic brake
rotor* and damage the rotor . Work carefully
and have a second person help you.
Never use the hexagonal socket in the handle
of the screwdriver to loosen or tighten the
wheel bolts.

> A pp lies to vehicles with cer amic brake rotors*: Use a sec­
o n d alignment p in* (sto re d in th e s pare w hee l well mold ­
in g) fo r the lower hole , fol low ing the descrip tion for the
fir st a lig nme nt pin .
264
-Pull the reversible blade from the screwdriv­
er before you use the hexagonal socket in
the handle to turn the wheel bolts.
- When mounting tires with
unidirectional
tread design
make sure the tread pattern is
pointed the right way¢
page 264.
-The wheel bolts should be clean and easy to
turn. Check for dirt and corrosion on the
mating surfaces of both the wheel and the
hub. Remove all dirt from these surfaces be­
fore remounting the wheel.
Tires with unidirectional tread design
Tires with unidirectional tread design mus t be
mounted with their tread pattern pointed in the
right direction .
Using a spare tire with a tread pattern
intended for use in a specific direction
When using a spare tire with a tread pattern in­
tended 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 incor­
rect direction, use the spare tire only tempora­
rily since the tire will not be able to achieve its
optimum performance characteristics with re­
gard to aquaplaning, noise and wear.
- We recommend that you pay particular atten ­
tion to this fact during wet weather and that
you adjust your speed to match road condi­ tions.
- Replace the flat tire with a new one and have it
installed on your vehicle as soon as possible to
restore the handling advantages of a unidirec­
tional tire.
Notes on wheel changing
Please read the information¢ page 243 if you
are going to use a spare tire which is different
from the tires on your vehicle.

After you change a tire:
- Check the tire pressure on the spare immedi­
ately after in stallation.
- Have the wheel bolt tightening torque
checked with a torque wrench as soon as pos­
s ible by your authorized Audi dealer or a
qualified servi ce stat ion .
- With steel and alloy wheel rims, the wheel
bolts are correctly tightened at a torque of 90
ft lb (120 Nm).
- If you notice that the wheel bolt s are corroded
and difficult 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 you r vehicle as soon as possi­
ble. Remount the wheel cover .
Until then, drive with extra care and at reduced
speeds.
& WARNING
- If you are going to equ ip your vehi cle w it h
t ir es o r rims which differ f rom those which
we re factory installed, then be s ure to read
the info rmat io n ¢
page 243.
- Always ma ke sure the damaged whee l or
even a flat tire and the jack and tool kit a re
prope rly secured in the luggage com part ­
me nt and are not loose in t he passenger
compar tment.
- In an accident o r sudden maneuver they
cou ld fly forward, inju ring anyone in the ve­
hicle.
- Always store damaged whee l, jac k and too ls
sec urely in the luggage co mpartment . Oth ­
erwise, in an accide nt or sudd en man euver
they could fly fo rw ar d, ca usin g injury to p as­
sengers i n the vehicle .
