An un sta ble surf ace under the jack ca n cause
the vehicle to slip off the jack . Always provide
a firm base for the jack on the ground . If nec­
essary place a sturdy board or similar support

A WARNING ~
-You or your passengers could be injured
while changing a wheel if you do not fo l­
low these safety preca utio ns:
- Position the vehicle jack on ly at the
designated 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 vehicle.
- 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 necessa ry,
use a stu rdy board under the jack.
- On hard, s lippery surface (such as t iles)
use a rubber mat or simi lar to prevent
the jack from slipping.
- To help prevent injury to yourself and
your passe ngers:
- 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 vehicle and
well away from the road and traffic .
- Make sure jack pos ition is correct, ad ­
just as necessary and then continue to raise the jack.
- Changes in temperature or load can af­
fect the height of the vehicle.

and the hub. Remove all dirt from these
surfaces before remo unting the wheel.
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in
the right direction.
Using a spare tire with a tread pattern
intende d fo r use in a specific direction
When using a spare tire with a tread pattern
intended for use in a specific direction, p lease
note the fo llowing:
- T he direction o f rotation is marked by an a r­
row on the side of the tire.
- If the spare t ire has to be installed in the in ­
correct di rection, use the spare tire only
temporarily since the tire will not be able to achieve its optimum performance character­
ist ics with regard to aquaplaning, noise and
wear.
- We recommend that you pay particular at­
tent ion to this fact during wet weather and
that you adjust your speed to matc h road
condit ions .
- Replace the flat tire w ith a new one and
have it installed o n your ve hicle as soon as
poss ible to restore the handling advantages
of a un id irect iona l tire .
Notes on wheel changing
Please read the information i:> page 246, New
t ires and repla cing tires and wheels
if you are
going to use a spare tire which is differen t
from the tires on your ve hicle.
Afte r you cha nge a tire :
-Check the t ire pressure on the spare imme ­
diately after installation .
- Have the wheel bolt tightening torque
checked with a torqu e wrench as soon as
possib le by your authorized Audi dealer or
a qualified servi ce station .
- With st eel 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 bolts are cor­
roded and difficult to turn while chang ing
a tire , they should be repl aced before you
check the t ightening torque.
- Repl ace the flat ti re w ith a new one and
have it installed on your vehicle as soon a s
possible. Remount the wheel cover .
Until then , dri ve with extra care and at re­
duced speeds.
A WARNING
