Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of wheel bolts is matched to the
factory installed rims. If different rims are fit­
ted, the correct wheel bolts with the right
length and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
secure ly and that the brake system functions
correctly .
In ce rtain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same mode l
~page 294.
_& WARNING
Improperly tig htened o r maintained whee l
bolts can become loose ca using loss of
contro l, a co llision and serious persona l in­
jury.
- Always keep the wheel bolts and the
threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop­
erly t ightened.
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can
become loose while driving if greased or
oiled, even if tightened to the specif ied
torque.
- Only use wheel bolts that belong to the
rim being installed.
- Never use different wheels bolts on your
vehicle.
-Always maintain the correct tighten ing
torque for the wheel bolts to reduce the
risk of a wheel loss. If the tightening tor­
que of the wheel bolts is too low, they
can loosen and come out when the veh i­
cle is moving. If the tightening torque is
too high, the whee l bolts and threads
can be damaged and the wheel can be­
come loose.
@ Note
The spec ified torq ue fo r the wheel bo lts is
90 ft lb (120 Nm) w ith a toleran ce of± 7,4
ft lb(± 10 Nm). Torque wheel bo lts diago- nally
. After changing a whee l, the torque
must be checked as soon as possible with a
torque wrench -preferably by an author­
i zed Audi dealer or qualified workshop.
Low aspect ratio tires
Your Audi is factory-equ ipped w ith low aspect
r atio tires . These tires have been tho roughly
tested and been se lected specifically for your
model for their superb perfo rmance, road fee l
and hand ling under a variety of d riving cond i­
tions . As k your au thor ized A udi dealer for
more de tails .
T he low aspect ratio of these t ires is ind icated
by a numera l of
55 or less in the tire's s ize
designation. The nume ra l represen ts the ra tio
of the tire's sidewall height in relation to its
tread width expressed in percentage . Conven­
tiona l tires have a he ight/width ratio of 60 or
more.
The performance of low- aspect-r atio tires is
p ar ticu la rly s ens iti ve to improper infl ation
p re ss ure. I t is th erefore im portant th at low
as pect ratio tires are inflated to the specified
pressure and that the inflation pressu re is
r e gularl y che cked and mainta ined. Tir e pre s­
su res should be ch ecked at least onc e a
month and alwa ys bef ore a long trip
~ page 249, Checking tire pressure.
What you can do to a void tire and rim
damage
Low aspect ratio tires can be damaged more
easily by impact w it h potholes, curbs, gull ies
o r r idges on the road, pa rticularly if the tire is
u nderinfla ted .
In order to minimize the occurrence of impact
damage to the tires of you r vehicle, we recom­
mend that you observe the follow ing p recau ­
tions:
- Always ma inta in recommended inflation
pressures. Check your tire pressure eve ry
2,000 miles (3,000 km) and add air if neces­
sary .
- Dr ive carefully on roads with potholes, deep
gullies o r ridges. The impact from dr iv ing ..,.

288 Emergency situations
heavy components such as the engine
b lock or transmiss io n are removed.
- W he n removing heavy components like
these, ancho r vehicle to ho ist o r add cor­
responding weig hts to ma inta in the cen ­
ter of g ravity . Othe rwise, the vehicle
might tilt or s lip off t he hoist, causing
ser ious p erson al injury.
(D Note
-Be awa re of the follow ing points befo re
li fting the vehicle:
- The vehicle should never be lifted or
jacked up from underneath the engine oil pan, the transmission housing, the
front or rear axle or the body side
membe rs. This could lead to ser ious
damage.
- To avoid damage to the underbody or
chassis frame , a rubber pad must be
i nserted between the floor jack and
the l ift points.
- Before driving over a workshop hoist,
check that the veh icle weight does not
exceed the permissible lifting capacity
of the hoist .
- Before driving over a workshop hoist,
ensure that there is sufficient clear­
ance between the hoist and low parts
of the vehicle.
