Where snow chains are mandatory oncer
tain roads, this normally also applies to
veh icles with all-wheel dr ive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design o f whee l 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
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same model
r=> page 270.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose caus ing loss of
c ont ro l, a co llision and serious persona l in
Jury .
- Always keep the wheel bolts and the
threads in the wheel hubs clea n so the
wheel bolts can turn easily and be prop er ly t igh tened .
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can
become loose while d riving 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 whee ls bolts on your
vehicle.
- Always maintain the co rrect tighten ing
torq ue fo r th e wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor
que of the wheel bo lts is too low, they
can loosen and come out w hen the veh i
cle is moving. If the tighteni ng torque is
too high, the whee l bolts and threads can be damaged and the whee
l can be
come loose.
@ Note
The specified torque for the whee l bolts is
90 ft lb (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm) . Torque wheel bolts diago
nally. After changing a whee l, the torque
must be checked as soon as possible with a
torque w rench -preferably by an author
i zed Audi dealer or qualified workshop .
Low aspect ratio tires
Your Audi is factory-eq uipped w it h low aspect
ra tio tires. These tires have been tho roughly
tested and been se lected specifically fo r your
model for their superb perfo rmance, road fee l
and handling under a variety of d riving condi
t ions . Ask your author ized A udi dealer for
more details.
T he low aspect ratio of these tires is ind icated
by a numera l of
55 or less in the tire's s ize
designation. The n umera l represents the ratio
of the tire's sidewall height in relation to its
tread width expressed in percentage. Conven
t iona l tires have a he ight/w idth ratio of 60 or
more .
The performance of low-aspect -ratio tires is
particularly sens iti ve to imp roper inflation
pressure. It is therefore important that low
a spect ratio tires are inflat ed to the specified
pre ssure and that the inflation pressure i s
regularly ch ecked and maintain ed. Tire pre s·
sure s should be checked at lea st once a
m onth and always bef ore a long trip
r=> page 231, Checking tire pressure .
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be d amage d more
easily by impact w ith potholes, curbs, gull ies
or ridges on t he road, particularly if the tire is
u nd eri nflated.

264 Emergency situations
fall from a lift if there is a change in ve
hicle weight distribution and balance.
This might happen, for example, when
heavy components such as the engine
block or transmission are removed .
- When removing heavy components like
these, anchor vehicle to hoist or add cor
responding weights to maintain the cen
ter of gravity. Otherwise, the vehicle
might tilt or slip off the hoist, causing
serious personal injury.
(D Note
- Be aware of the following points before
lifting 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
members. This could lead to serious
damage.
- To avoid damage to the underbody or
chassis frame, a rubber pad must be
inserted between the floor jack and
the lift points.
- Before driving over a workshop hoist,
check that the vehicle 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.

applied.
@) For the sake of the environment
- Changing the engine settings wi ll ad
versely affect emission levels . This is det
rimental to the environment and increas
es fue l consumption .
- Always observe env ironmental regula
tions when disposing of old engine oil,
used brake fluid, dirty engine coolant,
spent batteries or worn out tires.
- Undeployed airbag modules and preten
sioners might be classif ied as Perchlo
rate Material -spec ial handling may ap
ply, see www .dtsc .ca .gov/hazardous
waste/perch lorate . When the veh icle o r
parts of the restraint system including
airbag modules safety belts wit h preten
s ioners are scrapped, all appl icable laws
and regulations must be observed. Your
a utho rized Audi dea ler is familiar with
these requirements and we recommend
that you have your dealer perform this
serv ice for you .
