dri ve tempt you into taking extra risks. Always remember :
• When braking , an all -wheel drive vehicle handles in the same
way as a front drive vehicle .
• Drive carefully and reduce your speed on icy and slippery roads ,
even winter tires cannot help under bla ck ice conditions.

Wheel bolts
Wheel bolts must al wa ys be tightened to the correc t
tor que .
The design of wheel bo lts is matched to the factory installed rims. If
di fferent r ims a re fitted, t he co rrect w heel bo lts wi th the rig ht len gth
and correct ly shaped bolt heads m ust be used. This ensures that
w he els a re fitt ed se cu rel y and that t he bra ke syste m functi on s
correctly.
In certa in ci rc ums ta nces, yo u may no t use wheel bo lts fr om a
differ ent vehicle - eve n if it is the sa me
model=:> page 382.
& WARNING
Improperly tightened or maintained wheel bolts can become 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 bolts can turn easily and be properly tightened .
• Never grease or oil the wheel bolts and the threads in the wheel
hubs. They can become loose while driving if greased or oiled,
even if tightened to the specified torque .
• Only use wheel bolts 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 loosen and come out when the
vehicle is moving . If the tightening torque is too high, the wheel
bolts and threads can be damaged and the wheel can become
loose .
0 Note
The specified torque for the wheel bo lts is 9 0 ft lb (12 0 N m) with a
t olerance o f± 7,4 ft lb(± 10 Nm). T orque whee l bolts diago nally.
After changing a whee l, the torque must be checked as soon as possible with a torque wrench

Low aspect ratio tires
You r Aud i is fact ory- eq uip pe d w it h lo w aspect rati o tire s. T hese tir es

a variety of driving conditions. As k your authorized Audi d ealer for
m or e de tails.
The low aspect rat io o f th ese t ires is indicat ed by a nume ra l of 55 or
less in the tire's size designatio n. The numeral represents the ratio
o f t he tir e's s idewa ll he ig ht in r ela ti on to it s tread w idt h ex pressed
in percentage . Conventiona l tires have a height/width ratio of 60 or
more.
The performan ce of low -aspe ct-ratio tires is particularly sensitive to
improper inflation pressure . It is therefore important that low
aspect ratio tires are inflated to the specified pressure and that the
inflation pressure is regularly checked and maintained . Tire pres
sures should be checked at least once a month and alway s before a
long
trip :::::, page 331, "Checking tire pressure" .
What you can do to avoid tire and rim damage L ow a spect ratio tires can be damaged mo re easily by impact with
pot ho les, cu rbs, gull ies o r ridge s o n th e road, part icular ly if th e tire
