& WARNING (co ntinued )
• Snow chain s are available in different sizes. Always make sure
to follow the instructions provi ded by the snow chain manufac­
turer.
• Wh en driving with snow cha in s never drive fa ster than the
speed permitted for your specific snow chains .
• Always observe local regulations.
0 Note
• Remove snow chains before d riving on roads not cove red w it h
snow to avoid damaging t ires and wearing t he snow chains down
unnecessar ily .
• Snow chains, which come into direct contact wi th the wheel rim,
can scratch or damage it . The refore, make s ure that the snow chai ns
are sui tably covered. Chec k the pos it ion o f the snow cha ins afte r
driving a few yards and correct if necessary . Follow the instructions
from t he snow chain man ufacturer when doing so .
[ i] Tips
• Where snow chains are mandatory on certa in roads, this normally
also app lies to ve hicles wi th A ll W hee l Dr ive.
• If snow chains are installed, the tire p ress ures s houl d not be
sto red in the tire pressure moni to ring system (TPMS) . Otherwise the

Wheel bolts
Wheel bolts must al ways be tight ened to the c orrect
torqu e.
The desig n of whee l bolts is matc he d to the fa ct ory in stalled rims. If
different r ims are fitted, the cor rect wheel bo lts wi th t he r igh t length
and correctly s haped bolt hea ds must be used . Thi s ensures that
Safety first
wheels are fitted securely and that the brake system funct ions
cor rectly .
I n certa in circumstances, yo u may not use wheel bo lts from a
different vehicle -even if it is the same mo del.
& WARNING
Improperly tightened or maintained wheel bolts can be come
loose causing loss of control, a collision and serious personal
injury.
• Always keep the wheel bolts and the threads in the wheel hubs
clean so the wheel bolt s can turn easily and be properly tightened .
• Never grease or oil the wheel bolts and the th reads in the wheel
hub s. They can become loose while driving if greased or oiled, even
if tightened to the specified torque.
• Only use wheel bolt s that belong to the rim being installed .
• Never use different wheels bolts on your vehicle .
• Always maintain the correct tightening torque for the wheel
bolts to reduce the risk of a wheel loss. If the tightening torque of
the wheel bolts is too low, they can loo sen and come out when the
vehicle is moving . If the tightening torque is too high , the wheel
bolt s and thread s can be damaged and the wheel can become
loose.
0 Note
T he specified torq ue for the wheel bo lts is 90 ft lb (120 Nm) with a
t o le rance of ± 7,4 ft lb( ± 10 N m). Tor qu e wheel bo lts diagonally.
After cha nging a wheel, the torque must be checked as soon as
pos sible wi th a t orque w rench -prefer ably by an auth oriz e d Aud i
dealer or qualified workshop .•

-Put the tool case and the jack back in place in the luggage
compartment .
- Check the
tire pres su re on the spare wheel immediately
after mounting i t.
- As soon as possible, have the
tightening torques on all
wheel bolts checked with a torque wrench. The correct
tightening torque is 90 ft lb (120 Nm).
- Have the flat tire
repl aced as soon as possible.
lIJ Tips
• If you notice while changing a tire that the wheel bolts are
corroded and difficult to turn, then they should be replaced before
you check the tighten ing torque .
• Drive at reduced speed until you have the tighten ing torques
checked .a

The wheel covers must be removed to access the wheel
bolts .
Removal
-Pull the full wheel co ver off manually.
Installation

whe el b olt s
- Fit the wheel bolt wrench over the wheel bolt and push it
down as far as it will go.
- Close your grip around the
end of the wrench handle for
maximum torque and turn the wheel bo lts
counter-clock­
wise
about one single tur n in the direction of arrow
~ fig. 188.
Tightening
- Fit the wheel bolt wrench over the wheel bolt and push it
down as far as it will go .
- Close your grip arou nd th e
end of the wre nch handle for
max imum torque and turn eac h wheel bo lt
clockwise until
i t sit s tight .
& WARNING
• Using force without control to speed the wheel change up can
c ause the vehicle to slip off the jack and cau se seriou s personal
injuries.
• Do not loo sen the wheel bolt s more than one turn before you
raise the v ehicle with the jack. -Risk of in jury!
[I] Tips
• Never try and use the hexagonal socket in the handle of the screw­
driver to loosen or tighten the whee l bolts .
• If a wheel bolt sits
very tight, you may fi nd it easier to loosen by
caref ully pushi ng down on the end of the wheel bolt wrenc h with
one
foot only .
As you do, ho ld on to the car to keep yourself stab le and
take care not to slip. •

• The wheel bo lts shou ld be clean and easy to turn. Check for dirt
and corrosion on the mat ing surfa ces of both the whee l and the hu b.
Remove all d irt from these s urfaces before remounting the whee l.•
Tires with unidirectional tread design
Tires with unidirectional tread design must be mounted
with their t read 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 t he fo llow ing:
• The direct 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 direction in the
event of a flat ti re, use the spare tire only temporari ly since the tire
wi ll not be able to achieve its optimum pe rformance characterist ics
with regard to aq uaplaning, noise and wear .
• We recommend that particular attention be paid to this fact
during wet wea ther and that you adj ust you r speed to match road
conditions .
• Rep lace t he flat tire w ith a new one and have it ins talled on your

tightened with a torque of 90 ft lb (1 20 Nm ).
• If you not ice while ch anging a tire that the wheel bolt s are
corroded and difficult to turn, then they should be r eplaced before
yo u che ck the tightening torque.
• Repla ce the flat tire with a new one and have it installed on your
vehicle a s soon a s po ssible . Remount the wheel c over.
Until then, drive with e xtra care and at reduced speed s.
