.&_ WARNING
- Follow the manufacturer 's safe ty inst ru c­
tions on the de cal for the ai r pump and
the sealan t bottle .
- If a tire pressure of 1.8 bar cannot be
achieved after pumping for 5 minutes,
the ti re is too severe ly damaged. Do not
continue to drive .
- Seek pro fessional assistance if it is not
possible to repa ir the tire with the t ire
sealant.
(D Tips

Final check
App lies to vehicles : wi th Tire Mobility Sys tem
After d riv ing for a short d istance , tir e
pressure must be checked
~ After driving for about 10 mi nutes, stop and
check the tire pressure .
~ If tire pressu re is st ill at least 1.3 bar, in­
flate the tire to specified press ure (see dr iv­
er's side B-pillar), drive to the next repa ir
shop and have the tire and the sealant bot­

@ Tips
After a tire repair, have the sealant bo ttle
replaced at a dealersh ip. This restores full
functionality to t he Tire Mob ility System .

slip off the jack and ca use se rious pe r­
sonal in juries.
-Do not loosen the wheel bolts more than
one turn
before you ra ise the veh icle with
the jack. -Risk of inj ury!
(1) Tips
- N ever t ry and use the hexagona l socket
i n the handle of the screwdriver to loos­
en or tighte n the wheel bolts .
- If a whee l bolt sits very t ight, you may
find i t easie r to loosen by carefully p ush­

After you have loosened all wheel bolts and
raised the vehicle off the ground, perform the
following steps to remove and replace the
wheel:
Removing the wheel
.,. Use the hexagonal socket in the screwdriv­
er handle
to completely turn out the top­
most whee l bolt and set it aside on a
clean
surface c;, fig. 15 7.
.,. Screw the threaded end of the
alignment
pin from the tool kit hand-tight into the
now vacant bolt hole <=>
fig. 158 .
.,. Then completely unscrew the other wheel
bolts as described above.
.,. Take off the whee l leaving the alignment pin
in the bolt hole
c;,(D .
Putting on the wheel
.,. Lift the spare wheel and carefully s lide it
over the alignment p in to guide it in place
c;,(D .
.,. Use the hexagonal socket in the screwdriver
handle to screw in and tighten all whee l
bolts
slightly .
.,. Unscrew the alignment p in and insert and
tighten the remaining wheel bolt slightly like the rest .
.,. Turn the jack handle counter-clockwise to
lower the vehicle until the jack is fully re­
leased .
.,. Use the wheel bo lt wrench to tighten all
wheel bolts firmly ,=:,
page 208 . Tighten
t hem
crosswise, from one bolt to the ( ap­
proximately) opposite one, to keep the
wheel centered.

(D Note
When removing or installing the wheel,
the rim could hit the bra ke rotor and dam­
age the rotor . Wor k carefully and have a
second person help you.
N ever use the hexa gonal s ocket in the ha n­
d le of the screwdriver to loosen or t ighten
the wheel bolts.
- Pull the reversib le blade from the screw­
drive r before yo u use the hexagonal
socket in t he handle to t urn the whee l
bo lts .
- When mounting tires with
unid irectional
tread design
make s ure the tread pat­
te rn is poi nte d the r ight way
¢pag e 211.
- The wheel bolts should be clea n and easy
to tu rn . Ch eck for dirt and corros ion on
the mat ing su rfaces of both the whee l
a nd th e hu b. Remove a ll dir t fro m these
s ur fa ces before remo unting the wheel.
Notes on wheel change
Pl ease rea d the information ¢ page 191, New
tires and replacing tires and wheels,
i f you are
going to use a spare t ire which is different
from the tires on your ve hicle.
Afte r you change a tire:
- Check the tire pressure on the spare imme ­
diately after mounting .
- Have the wheel bolt tightening torque
che cked with a torque wrench as soon as
possible by your authorized Audi dealer or
a qualified service station.
- With steel and alloy wheel rims, the wheel
bolts are correctly tightened at a torque of
90 ft lb (120 Nm) .
- If you notice while changing a tire that the
wheel bolt s are co rroded and diffi cult to
turn , then they should be replaced before
you check the t ightening torque.
What do I do now? 211
- 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 go ing to e quip your ve hicl e
wit h tires o r rims which differ from those
which were factory installed, t hen be
sure to read the information¢
page 191,
New tires and replacing tires and
wheels .
-Always sto re the tools secu rely in lug­
gage compartment. Othe rwise, in a n ac­
cident o r su dd en maneuv er they cou ld fly
forwa rd, causi ng injury to passe ngers in
the vehicle.
Tires with unidirectional tread design
Tires with unidirectional tr ead design must be
mounted with their tread pattern pointed the
right dire ction.
A u nidirectional tire can be identified by ar­
rows on the sidewall,
which point in the direc ­
tion of t he rota tion. Yo u m ust follow the
s p ecifie d direction of rot ation. This i s nece ssa ­
r y in order fo r these tires to develop t heir op­
timum charac ter istics regard ing grip, road
no ise, wear, and hydrop la ning.

cation, Instrument Panel left .
.. Remove the blown fuse with the plastic clip
provided. The cl ip is located on the holder in
the fuse box .
.. Replace a blown fuse (recognizable by the
melted metal str ip ins ide) with a fuse of the
same amperage .
.. Firmly snap the cover back onto the instru­

.. Remove the plastic from its retainer in the
fuse box cover (left face end of the instru­

and pull it out .
.. If the fuse is burned out (recognizable by
melted strips of metal), replace it with a
new fuse
of the same rating.
.. Replace the fuse cover .
.. Push the two slides to the rear
o fig. 160.
Install the fuse cover carefully to prevent
water from enter ing .
The various electrical circuits are protected by
fuses. The fuses are clustered in a centralized unit. The unit is located behind the face panel
at the end of the instrument panel.
You are well advised to keep a supply of spare
fuses in your vehicle. Fuses with the proper
ampere ratings are available at your author ­
ized Audi dealer.
A WARNING -
Do not repa ir fuses and never replace a
blown fuse with one that has a higher amp
rating. This can cause damage to the elec­
trica l system and a fire.
(D Note
If a new fuse burns out again after shortly
have you have installed it, have the electri­
ca l system checked by your authorized
Audi dealer.
