A WARNING
You o r your passengers could be i nju red
while changing a wheel if you do not fo l­
l ow these sa fety precaut ions:
- If you have a flat tire, move a safe dis­
tance off the road. Turn off the engine,
turn the eme rgency flashers on and use
-

other warning devices to alert other mo­
torists.
- Make sure that passengers wait in a safe
place away from the vehicle and well
away from the road and traffic.
- To help prevent the vehicle from moving
suddenly and possibly slipping off the
jack, always fully set the parking brake
and block the wheel diagonally opposite
the wheel being changed. When one
front wheel is lifted off the ground, plac­
ing the Automatic Transmission in "P"
(Park) will
not prevent the vehicle from
moving.
- Before you change a wheel, be sure the
ground is level and firm. If necessary,
use a sturdy board under the jack.
- After installing the spare wheel, make
sure that you replace the flat tire/wheel
in its storage area properly and tighten
the knurled retaining screw securely.
@ Tips
Before changing the wheel, you must acti·
vate the jacking mode, so that the auto­
matic controls for the Adaptive Air Sus­
pension do not make it more difficult to
lift the vehicle with the jack ¢

After changing a wheel
A wheel change is not complete without the
doing the following.
.. Store and secure the wheel you replaced in
the spare wheel well.
.. Replace the tools and the jack in their prop­
er location.
.. Check the
tire pressure on the spare wheel
immediately after mounting it.
.. As soon as possible, have the
tightening
torques
on all wheel bolts checked with a
torque wrench. The correct tightening tor­
que is 90
ft lb (120 Nm).
.. Have the flat tire
replaced as soon as possi­
ble .
(D Tips
-If you notice that the wheel bolts a re
corroded and difficult to turn while

@ Tips
-Never use the hexagonal socket in the
handle of the screwdriver to loosen or
tighten the wheel bolts.
- If a whee l bolt is very tight, you may find

28 4 Con sum er Inf orm ati on
comp lexity of today's automobi les, have
steadi ly reduced the scope of maintenance
and repairs which can be carried out by vehicle
owners.
Also, s afety an d e nvir onm ent al con­
cerns place very strict limits on the nature of repairs and adjustments to engine and trans ­
miss ion pa rts which an owner can perform .
Maintenance, adjustments and repa irs usua lly
require special tools, testing devices and oth­
er equipment avai lab le to specially trained
workshop personnel in order to assure proper
performance, reliab ility and safety of the vehi­
cle and its many systems .
Improper ma intenance, adjustments and re ­
pa irs can impair the operation and reliab ility
of your vehicle and even void your vehicle war­ ranty. Therefo re , proof of servici ng in accord­
ance w it h the ma intenance sched ule may be a
condition for upholding a possible warranty
claim made within the warran ty period .
Above all, operational safety can be adve rsely
affected, c reating unnecessary risks for you
and your passengers.
If in doubt about any servicing, have it done
by your author ized Audi dealer or any other
p roperly equipped and qualified wor kshop .
We strong ly urge you to give your authorized
Audi dealer the opportunity to perform all
schedu led maintenance and necessary repairs .
Your dea ler has the facilities, original parts
and tra ined spec ialists to keep your vehicle
running properly .
