Wheels
Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/tighten
easily .
Rims
Rim s with a bolted r im ring * or with bolted wheel
covers* consist of multiple pieces. These compo­
nents were bolted together using special bolts
and a special procedure . You must not repair or
disassemble
them ¢_&. .
..&, WARNING
Wheel bolts that are tightened or repaired in­
correctly can become loose and result in loss
of vehicle control , which increases the risk of
an accident. For the correct tightening specifi­
cation, see
¢ page 35 7, After changing a
wheel.
- Always keep the wheel bolts and the
threads in the wheel hub clean and free of
grease.
- Only use wheel bolts that fit the rim.
- Always have damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility. Never repair or disassemble
rims yourself, because this increases the risk
of an accident .
Winter tires
Winter tires significantly improve the vehicle 's
handling when driving in winter conditions. Be­
cause of their construction (width, compound,
tread pattern) , summer tires provide less trac­
tion on ice and snow.
.,. Use winter tires on all four wheels .
.,. Only use winter tires that are approved for your
vehicle.
.,. Please note that the maximum permitted
speed may be lower with winter tires
¢ _&. .An
authorized Audi dealer or authorized Audi Serv­
ice Facility can inform you about the maximum
permitted speed for your tires.
.. Check the tire pressure after installing wheels
¢ page 336.
342
The effectiveness of winter tires is reduced great­
ly when th e tread is worn down to a depth of
0.157 inch (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages, re ­
gardless of the remaining tread.
'
..&, WARNING
- Never drive faster than the maximum per ­
mitted speed for your tires. This could cause
the tires to heat up too much. This increases
the risk of an accident because it can cause
the tire to burst .
- Always adapt your driving to the road and
traffic conditions . Drive carefully and reduce
your speed on icy or slippery roads . Even
winter tires can lose traction on black ice.
{® For the sake of the environment
Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fuel
consumption.
(D Tips
You can also use all season tires instead of
winter tires. Please note that in some coun­
tries where winter tires are required, only
winter tires with the
& symbol may be per­
mitted.
Snow chains
-
Snow chains not only improve the driving in win­
ter road conditions, but also the braking.
.. Only install snow chains on the front wheels.
This applies also to vehicles with all wheel drive* .
.. Check and correct the seating of the snow
chains after driving a few feet, if necessary . Fol­
low the instructions from the manufacturer .
.,. Note the maximum speed of 30 mph (SO km/
h). Note the local regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
.,.

Emergency assistance
• To open the side pane l, turn the lock and re­
move the
cover @*/ @ ¢ fig. 283.
• Lift the cargo floor using the plastic handle @
un til the cargo floor engages behind the tabs
© in both side panels¢ fig. 284 (upper im­
age) .
• Fold the cargo floor back before closing the
luggage compartment lid.
Vehicle tool kit and cargo floor cover
App lies to: ve hicles w ith versio n 2
The vehicle too l kit, tire mobility kit* and com­
pressor* are stored in the luggage compartment
under the cargo floor
cover @¢ fig. 283 .
• Engage the plastic hook® in the luggage com­
partment
seal ¢ fig. 284.
• Fold the cargo floor back before closing the
luggage compartment lid .
.&_ WARNING
Improper use of the vehicle jack can cause se­
r ious personal injuries.
- Never use the screw driver hex head to
tighten wheel bolts, since the bolts cannot
attain the necessary tightening torque if you
use the hex head, potentially causing an ac­
cident.
- T he factory-supplied jack is intended only
for your vehicle model. Under no circum­
stances should it be used to lift heavy
vehicles or other loads; you risk injuring
yourself.
- Never start the engine when the vehicle is
raised, which could cause an accident.
- Support the vehicle securely with appropri­
ate stands if work is to be performed under­
neath the vehicle; otherwise, there is a po­
tent ial risk for injury.
- Never use the jack supplied with your Audi
on another vehicle, particularly on a heavier
one. The jack is only suitable for use on the
vehicle it came w ith.
@ Tips
The vehicle jack* in your vehicle is mainte­
nance-free.

App lies to: vehicles with tire mobility kit
• Read and fo llow the important safety precau-
tions
in ¢ page 353.
• Set the parking brake.
• Move the selector lever into the P position.
• Check if a repair with the tire mobility kit is pos­
sible

Tire: t ir e damage that cannot be repaired
The tire repair is only meant for temporary use .
Change the spare tire as soon as possible
c:;> .&..
If the tire is pierced by an object such as a nail ,
do not remove the object from the tire.

> 00 m
The tire repair set is able to be used at tempera­
tures as low as -4 °F ( -20 °C).
The tire mobility kit may not be used :
-if the tire has cuts or punctures that are larger
than
0.16 in (4 mm) (!)¢ fig. 285.
-if the rim is damaged @.
- if you drove with very low tire pressure or with-
out air in the tire @.
In this case, see an authorized Aud i dea ler or au­
thorized Audi Service Facility for assistance.
~ WARNING
-Please note that the tire mobility kit cannot
be used in all situations, and that it may on­
ly be used temporarily.

_& WARNING
You or your passengers could be injured while
changing a wheel if you do not follow these
safety precautions:
- If you have a flat tire, move a safe distance
off the road. Turn off the engine, turn the emergency flashers on and use other warn­
ing devices to alert other motorists.
- 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 be­
ing changed. 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.
- Always store the vehicle tool kit, the jack
and the replaced tire in the luggage com­
partment

Emergency assistance
_& WARNING
-Always read and follow all WARNINGS and in-
formation
c:> .&. in Raising the vehicle on
page 359
and c:> page 361.
After changing a wheel
A wheel change is not complete without the do­
ing the following.
.. Always store the vehicle tool kit, the jack* and
the replaced tire in the lugg age compartment
c:> page 253.
.. Check the tire pressure on the spare wheel im­
mediately after mounting it .
.. As soon as possible, have the tightening tor­
ques
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.
@ Tips
-If you notice that the wheel bolts are cor­
roded and difficult to turn while changing a
tire, they should be replaced before you
check the tightening torque.
- Drive at reduced speed until you have the tightening torques checked.
- After changing a wheel, the tire pressure in
all four tires must be checked/corrected and
the tire pressure monitoring indicator must
be stored in the MMI
c:>page 346.
Decorative wheel covers
Applies to : vehicles wit h decorative w heel covers
The decorative wheel covers must be removed
first to access the wheel bolts.

¢fig. 290.
Tightening
.. Slide the wheel wrench onto the wheel bolt as
far as it will go.
.. Take tight hold of the end of the wrench handle
and turn each wheel bolt
clockwise until it is
seated.
A WARNING
-Do not use force or hurry when changing a
wheel - you can cause the vehicle to slip off
the jack and cause serious personal injuries.
-Do not loosen the wheel bolts more than
one turn
before you raise the vehicle with
the jack.
-You risk an injury.
(D Tips
-Never use the hexagonal socket in the han­
dle of the screwdriver to loosen or tighten
the wheel bolts.
-If a wheel bolt is very tight, you may find it
easier to loosen by carefully pushing down
on the end of the wheel bolt wrench with
one foot only. As you do so, hold on to the

checked with a torque wrench as soon as pos -
Emergency assistance
sible by your authorized Audi dealer or a
