A wheel change is not complete without the
doing the following .
.,. Always store the vehicle tool kit, the jack*,
and the replaced tire in the l uggage com­
partment ¢
page 132 .
.,. Check the tire pressure of the spare tire as
soon as possible .
.,. As soon as possible, have the
tightening
torques
on all wheel bo lts checked with a
torq ue wrench . The correct tightening tor­
que is 90
ft lbs. (120 Nm).
.,. Have the flat tire
replaced as soon as possi­
ble .
(j) Tips
-If you notice that the whee l bolts are
corroded and difficult to turn while
changing a t ire, they should be replaced
before you check the tighten ing torque.
- Drive at reduced speed until you have the
tightening torques checked .
Decorative wheel covers

What do I do now ? 265
@ Tips
-Never use the hexagona l socket in the
hand le of the screwdr iver to loosen or
tighten the wheel bolts.
- If a wheel bo lt is very tight, you may find
it eas ier to loosen by carefully pushing
down on the end of the wheel bolt
wrench with
one foot only . As you do so,
hold o n to the car to keep your balance
and take care not to slip .
Raising the vehicle
The vehicle must be lifted with the jack first
before the wheel can be removed .

• Activate the parking brake to prev ent the
veh icle from rolling unintentionally .
• Shift into
1st ge ar on veh icles with manual
transmiss ion or move the selector lever to
the P position on vehicles w ith automatic
transmission .
• Find the
mark ing (imprint) on the sill that is
nearest the wheel that will be changed .,..

266 What do I do n ow ?
c:> fig. 203 . Behind the marking, there is a
lifting p oint on the sill for the veh icle jack.
• Turn the
veh icle j ack located under the lift­
ing point on the si ll to raise the jack until
the jaw
c:> fig. 204 ® covers the notch on
the vehicle
c:> &_ c:>(D .
• Align t he vehicle jack so the jaw ® covers
the notch and the base plate @ is flat on
the floor. The base plate @ must be
vertical
under the lifti ng point @.
• Install the rod on the vehicle jack: Insert the
rod into the opening on the handwheel. Turn
the rod left or right to secure it .
• Contin ue raising the jack with the rod until
the wheel lifts off the ground slightly.
Position the vehicle jack
onl y under the desig­
nated lifting points on the sill
c:> fig. 203 .
There is exactly one location for each wheel.
The jack must not be positioned at any other location
c:> ,&. c:>(D .
Soft ground under the jack can cause the ve­
hicle to slip off the jack. Always place the jack
on firm ground. Use a flat, stable support if necessary . Use a non-slip surface such as a
rubber mat on a
slipp ery surfac e such as tile .
A WARNING
-You or your passengers could be injured
wh ile chang ing a wheel if you do not fol­
low these safety precautions :
- Position the vehicle jack only at the
des ignated lifting points and align the
jack. Otherwise, the vehicle jack could slip and cause an injury if it does not
have sufficient hold on the veh icle .
- A soft or unstable surface under the
jack may cause the veh icle to slip off
the jack . A lways provide a firm base for
the jack on the ground.
If necessary,
use a sturdy board under the jac k.
- On hard, slippery surface (such as tiles)
use a rubber mat or similar to preven t
the jack from s lipping.
- T o help p revent injury to yourself and
yo ur passengers: -
Do not raise the vehicle until you are
sure the jack is securely engaged.
- Passengers must not remain in the ve­
hicle when it is jacked up.
- Make sure that passengers wait in a
safe place away from the veh icle and
well away from the road and traffic .
- Make sure jack pos ition is correct, ad­
j ust as necessary and then cont inue to
raise the jack.
(D Note
Do not lift the vehicle by the sill. Position
the veh icle jack only at the designated lift­
i ng points on the sill. Otherwise, your vehi­
cle will be damaged.

the mating surfaces of both the w heel
and the hub. Remove all d irt from these
surfaces before remounting the whee l.
- Do not use the hexagonal socket in the
sc rewd river handle to loosen or t ighten
the whee l bolts.
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in
the right direction.
U si ng a spa re tire with a tread pattern
intended for use in a specific di rection
When using a spare t ire with a tread patter n
intended for use in a spec ific d irection, please
note the following :
- The d irect ion of rotation is marked by an
ar­
row on the side of the t ire .
-If the spare tire has to be insta lled in the in­
correct d irect ion, use the spare tire only
temporarily s ince the tire will not be able to
achieve its optimum performance cha racte r­
istics w it h regard to aquap la ni ng, no ise and
wear .
- We recommend that you pay part icu lar at­
t en tion to th is fact during wet weather and
that you adjust your speed to match road
condi tions.
- Replace the flat t ire wi th a new one a nd
have it insta lled o n you r vehicle as soo n as
pos sible to res to re the hand ling advant ages

268 What do I do now?
-Check the tire pressure on the spare imme­
diately after installation.
- Have the wheel bolt tightening torque
checked with a torque wrench as soon as possible by your authorized Audi dealer or
qualified workshop.
- With steel and alloy wheel rims, the wheel
bolts are correctly tightened at a torque of
90 ft lbs. (120 Nm).
- If you notice that the wheel bolts are cor­
roded 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 your vehicle as soon as
possible. Remount the wheel cover.
Until then, drive with extra care and at re­
duced speeds.
A 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 248,
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 com­
partment and are not loose in the pas­
senger compartment.
- In an accident or sudden maneuver they
could fly forward, injuring anyone in the
vehicle.
- Always store damaged wheel, jack and
tools securely in the luggage compart­
ment. Otherwise, in an accident or sud­
den maneuver they could fly forward,
causing injury to passengers in the vehi­
cle.
@ Note
Do not use commercially available tire
sealants. Otherwise, the electrical compo­
nents of the tire pressure monitoring sys­
tem* will no longer work properly and the
sensor for the tire pressure monitoring system* will
have to be replaced by quali­
fied workshop.
