Taking the wheel off/installing the spare
Follow these instructions step-by-step for changing the
wheel
Fig. 274 Changing a
wheel: using the
screwdriver handle
(with the blade
removed ) to turn the
bolts
Fig . 275 Changing a
wheel: alignment pin
inside the top hole
After you have loosened all wheel bolts and raised the vehicle
off the ground, remove and replace 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. 274 .
- Screw the threaded end of the
alignment pin from the
tool kit hand-tight into the empty bolt hole=> fig. 275 . -
Then remove the other wheel bolts as described above.
- Take off the wheel leaving the alignment pin in the bolt
hole.
Putting on the spare wheel
Lift the spare wheel and carefully slide it over the align­
ment pin to guide it in place.
- Use the hexagonal socket in the screwdriver handle to
screw in and tighten all wheel bolts
slightly.
- Remove the alignment pin 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 released .
Use the wheel bolt wrench to tighten all wheel bolts firmly
=> page 338. Tighten them crosswise, from one bolt to
the (approximately) opposite one, to keep the wheel
centered .
(I) Tips
Never use the hexagonal socket in the handle of the screwdriver to
loosen or tighten the wheel bolts.
• Pull the reversible blade from the screwdriver 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 341.
• 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 surfa ces before remounting the wheel. •

Tires with unidirectional tread design
Tires with unidirectional tread design must be mounted
w ith their tread pattern pointed in the right direction .
Using a spare tire w ith a tread pattern intended for
u se in a specific direction
When using a spare tire w ith a tread pattern intended for use in a
spec ific direction, please note the fo llow ing:
• The d irect ion of rotation is marked by an arrow on the side of the
tire.
• If the spare tire has to be installed in the incorrect direct ion, use
t he spare t ire only temporar ily since the tire w ill no t be ab le to
achieve its optimum pe rformance character istics with rega rd to
aquap lan ing, no ise and wear.
• We recommend that you pay particular attent ion to t his fact
during wet wea ther and that you adjust you r speed to match road
conditions .
• Rep lace the flat tire w it h a new one and have it ins talled on your
vehicle as soon as poss ible to resto re the handling advantages of a
unidirectio na l tire .•
Notes on wheel changing
Please read the in forma tion => page 318, "New t ires and replacing
tires and wheels" if you are going to use a spare t ire which is different
from the tires on yo ur vehi cle.
After you change a t ire:
• Check the tire pressure on the spare immediately after installa­
tion.
• Have the wheel bolt t ightening torque checked with a torque
wren ch as soon a s possible by your authorized Audi dealer or a qua l­
i fied serv ice stat ion.
Safety first • 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 bolts are corroded and difficult to
turn while changing a tire, they should be replac ed before you check
the tightening torque.
• R epla ce the flat tire with a new one and have it install ed on your
vehicle as soon as possible. Remount the wheel cover.
Until then, drive with extra care and at reduced speed s.
& 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 =>

the jack and tool kit are prope rly secured in the luggage compart ·
ment and are not loo se in the pa ssenger compartment.
• In an accident or sudden maneu ver they could fly forward ,
injuring anyone in the vehicle .
• Always store dam aged wheel , jack and tools secu rely in the
luggage compartment. Otherwi se, in an accident or sudden
maneuver they could fly fo rward , caus ing inju ry to passengers in
the vehicle .
• Do not u se commercially available tire sealants . Otherwi se, the
electrical component s of the tire pre ssure monitoring system * will
no longer work properly and the sensor for the t ire pressure moni ·
toring sy stem* will have to be replaced b y a qualified work shop .•

Starting with jumper cables
I f necess ary, the engine can be started b y connectin g it to
t he bat tery of another vehicle.
If the e ng ine shou ld fa il to start because of a discharged or weak
battery, the batte ry can be connected to t he battery of
another
veh icle, us ing a pair of jumper cables to start the eng ine .
Jumper cables
Use only jumper cables of suffic iently large cross section to carry the
sta rter cur rent s afely . Refer to the m an ufa ct ur er's specificat ions.
Use only j umpe r cab les with
insulated te rmi nal clamps wh ich are
distinct ly marked :
plu s(+) cable i n most cases colored red
minus (-) cable i n most cases colored black .
& WARNING
Batterie s contain el ectricity, acid, and gas . Any of the se can cause
very serious or fatal injury. Follow the inst ructions below for safe
handling of your vehicle 's battery.
• Always shield your eyes and avoid leaning over the battery
whenev er po ssible .
• A discharged battery can freeze at temperatures just below
32 °F (0 °C ). Before connecting a jumper cable, you must thaw the
frozen battery completely, otherwise it could explode.
• Do not allow battery acid to contact eyes or sk in . Flush any
contacted area with water immedi ately .
• Improper use of a booste r battery to start a vehicle may cause
an explosion .
• Vehicle batteries generate e xplosive gases. Keep sparks, flame
and lighted cigarettes away from batterie s.
• Do not try to jump start any vehicle with a low acid level in the
battery.
• The voltage of the booster battery must also have a 12-Volt
rating. The capacity (Ah) of the booster battery should not be
lower than that of the discharged battery . Use of batteries of
different voltage or substantially different "Ah " rating may cau se
an e xplosion and personal injury.
• Never charge a frozen battery . Gas trapped in the ice may cause
an explosion.
• Never charge or use a battery that has been frozen. The battery
c ase may have be weakened .
• Use of batteries of different voltage or substantially different
capacity (Ah) rating may cause an explosion and injury . The
capacity (Ah) of the booster battery should not be lower than that
of the discharged battery. .,_
