& WARNING
Using the wrong snow chains for your vehicle or installing them
incorrectly can increase the risk of loss of control leading to
serious personal injury.
• Snow chains are available in different sizes . Always make sure
to follow the instructions provided by the snow chain manufac
turer.
• When driving with snow chains never drive faster than the
speed permitted for your specific snow chains.
• Always observe local regulations.
0 Note
• Remove snow chains befor e driving on roads not covered w it h
snow to avoid dama gin g tir es and wearing t he snow chai ns dow n
unnece ssaril y.
• Snow chains, which come into direct contact with t he wheel rim,
can scratch o r damag e it. Ther efore, ma ke sure th at th e snow cha ins
are suitably covered. C hec k the pos it io n of the snow cha ins afte r

Wheel bolts
Whe el bolts must alway s be tight en ed to th e corre ct
to rqu e.
T he design of wheel bolts is matche d to the fac to ry installed rims. If
differe nt rims ar e fitte d, the cor rec t wheel bolts with the r ight length
and co rrectly s haped bolt hea ds must be used. Th is ensures that
w heel s are fitted s ecur ely and that t he brak e sys te m fun ction s
correctly .
I n certai n circumstances, yo u may not use wheel bolts from a
different veh icle -even if it is th e sam e mode l~
page 345.
& 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 thread s 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 sp eci fied tor qu e for th e wheel bolts i s 90 ft lb ( 120 Nm) wi th a
tole rance of ± 7,4 ft lb( ± 10 Nm). Torque wheel bo lts diagonally. .,_

Before returning the jack to its place, retract the jack arm fully.
& WARNING
• Never use the screw drive r he x head to tighten wheel bolts,
s in ce the bolts cannot attain the necessary tightening torque if
you use the hex head , potentially cau sing an accident .
• The factory-supplied jack i s intended only for your vehicle
model. Under no circumstances should it be used to lift hea vy
vehicles or other loads; you ri sk injuring your self .
• Never start the engine when the vehicle is raised , which could
cause an accident.
• Support the vehicle securely with appropriate stands if work i s
to be performed underneath the v ehicle; otherw ise, there is a
potential risk for inju ry .•
Space-saving spare tire (compact

- Turn the large screw=> fig. 236 counter-cloc kw ise .
- Tak e ou t the spare tir e.
- Unhook the cargo floor before closing the rear lid.
Securing the replaced tire
- Place the wheel wi th t ire in the s pare wheel well and
secu re t he wheel with the large screw.
- Unho ok th e ca rgo floor befo re closin g the re ar li d.
Using the spare tire (compact spare tire)
The compact spare tire is only intended for emergencies until you can
re ach a rep air sho p. Rep lace i t as quick ly as possib le wit h a standard
wheel and tire.
Th ere are some restr ictions on the use of the compac t spare ti re. The
compact spare t ire has been des igned specifically fo r you r type of
vehicle . It must not be swapped with a compact spare tire from
another type of vehicle .
Snow chains
For technical reasons, the use of snow chains on the compact spa re
t ire is
not permitted .
If you do have to dr ive wi th snow chains and a front tire fails, mo unt
the spare wheel with tire instead of a rear tire. Install the snow chains on the rear tire and use it to replace the defective front tire . ._

& WARNING (continued)
• Make sure that passengers wait in a safe place away from the
vehicle and well away from the road and traffic.
• To help prevent the vehicle from moving suddenly and possibly
slipping off the jack, always fully set the parking brake and block
the wheel diagonally opposite the wheel being changed with the
folding chocks or other objects. When one front wheel is lifted off
the ground, placing the Automatic Transmission in "P" (Park) will
not prevent the vehicle from moving.
• Before you change a wheel, be sure the ground is level and
firm. If necessary, use a sturdy board under the jack.
• After installing the inflatable spare tire, make sure that you
replace the flat tire/wheel in its storage area properly and tighten
the knurled retaining screw securely.
0 Note
If you are changing the wheel on a steep incline, use a rock or similar
object to block the opposite wheel to prevent the vehicle from
moving.
[I) Tips
Obey all laws.•

A wheel change is not complete without the doing the
following.
- Store and secure the wheel you replaced in the spare
wheel well.
- Replace the tools and the jack in their proper location.
- Check the
tire pressure of the spare tire as soon as
possible.
- 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
replaced as soon as possible.

(I) Tips
• If you notice that the wheel bo lts are co rroded and difficult to turn
while changing a tire, they should be replaced before you check the
t ighteni ng to rque.
• Drive at reduced speed until you have the tightening torques
checked. •

• When mounting tires with
unidirectional tread design make sure
t he t read p attern is po inte d the rig ht way =:>
page 326.
• The wheel bo lts shou ld be clean and easy to turn. Check for dirt
and cor rosion on the mat ing surfa ces of both the whee l and the hub.
Remove all d irt from these surfaces before remounting the whee l.•
Tires with unidirectional tread design
Tires with unidirectional tread design must be mounted
with their tread pattern pointed in the right direction.
Using a spare tire with a tread pattern intended for
use in a specific direction
When using a spare tire w ith a tread pattern intended for use in a
spe cific d irec tion, please note the follow ing :
• The direction of rotation is marked by an
arrow on the side of the
tire .
• If the spare tire has to be installed in the incorrect d irect ion, use
t he spare tire only temporari ly since the tire wi ll not be ab le to
achieve its optimum performance characte rist ics with regard to
aquap lan ing, noise and wear.
• We recommend that you pay particular attention to this fact
during wet weather an d that you adjus t you r speed to match road
conditions.
• Rep lace t he fl at t ire w ith a new one and have it ins talled on your
vehicle as soon as possible to restore the handling advantages of a
unidi rectional tire .•

from the tires on your vehicle .
After you change a tire :
• Che ck the tire pre ssure on the spare immediat ely after installa
tion .
• Have the wheel bo lt tightening torque checked with a torqu e
wren ch as soon as possible by your autho rized Aud i deale r or a qual
ified work shop .
• With steel and all oy wheel rims , the wheel bolts are co rrectly
tightened at a torque of 90 ft lb (120 Nm ).
• If you noti ce that the wheel bolts are corroded and difficult to
turn while changing a tire, they should be rep laced before you chec k
the tightening torque .
