Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/t ighten
easi ly.
Rims
R ims with a bolted rim ring* or with bolted wheel
covers* consist of m ultip le pieces. These compo­
n ents were bolted toge ther using specia l bolts
a nd a specia l procedu re. You must not repair or
disassemble them¢
A.
A WARNING
Wheel bolts that are t ightened or repaired in­
co rrectly can become loose and result in loss
of vehicle control, which increases the risk of
an acc ident. For the correct tightening specifi­
cation, refer to¢
page 260.
-Always keep the wheel bolts and the
threads in the whee l hub clean and free of
grease.
- Only use wheel bolts that fit the rim.
- Always have damaged r ims repaired by an
authorized Audi dealer or authorized repair
facility. Never repair or d isassemble rims
yourself, because th is increases the r isk of
an acc ident .
Winter tires
W inte r tires s ignificantly improve the vehicle's
h andling when d rivi ng in winter condit ions. Be­
cause of the ir constr uction (width, compound,
t read pattern), summe r ti res provide less trac­
tion on ice and snow.
"'U se winte r tir es on all four wheels.
"' Only use winter t ires that a re approved for your
vehicle.
"' Please note that the maximum permitted
speed may be lower with winter tires
¢ &, .
Wh eel s
Your authorized A udi dealer or authorized re­
pair facility can inform you about the maximum
permitted speed for your tires.
"' Check the tire pressure after insta lling wheels
¢page 246.
The effectiveness of winter tires is reduced great­
ly when the 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 rema ining t read .
A WARNING
'---
-Never d rive faster than the max imum pe r­
mitted speed for your tires. This could ca use
the t ires to heat up too mu ch. This in cr eases
the r isk of an accident because it can ca use
the t ire to burst.
- Always adapt your driving to the road and
traffic cond itions. Drive carefully an d reduce
your speed on icy or slippery roads. Even
winter t ires can lose tract ion on black ice.
@ For the sake of the environment
Reinsta ll summer tires a t the app ropr iate
time, beca use they prov ide bette r handling
when roads are free of snow and ice . Summer
tires cause less road noise, tire wear and fue l
consumpt ion.
(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, on ly
winter tires w ith the
& symbo l may be per­
mitted.
Snow chains
Snow chains improve traction in the snow.
"' On ly install snow chains on the front wheels.
"' Check and co rrect the seating of the snow
chains if necessary after driving a few feet. Fol­
low the instructions from the manufacturer.
"' Note the maximum permitted speed when dr iv­
ing with snow chains. Do not exceed 30 mph
(SO km/h) . ...

Emergency assistance
After you have loosened all wheel bolts and raised the vehicle off the ground, remove and re­
place the wheel as follows:
Removing the wheel
.,. Use the hexagonal socket in the screwdriver
handle
to completely remove the topmost
wheel bolt and set it aside on a
clean surface
.::!> fig. 223.
.,. Screw the threaded end of the alignment pin
from the tool kit hand-tight into the empty bolt
hole¢
fig. 224 1> .
.,. Then remove the other wheel bolts as described
above.
.,. Take off the wheel leaving the alignment pin in
the bolt hole ¢0 .
Putting on the spare wheel
.,. Lift the spare wheel and carefully slide it over
the alignment pin to guide it in place ¢0 .
.,. Use the hexagonal socket in the screwdriver
handle to screw in and tighten all wheel bolts
slightly .
.,. Remove the alignment pin and insert and tight­
en the remaining wheel bolt slightly like the
rest.
.,. Turn the jack handle counter-clockwise to lower
the vehicle until the jack is fully released.
.,. Use the wheel bolt wrench to tighten all wheel
bolts firmly ¢
page 260 . Tighten them cross­
wise,
from one bolt to the (approximately) op­
posite one, to keep the wheel centered.
0 Note
When removing or installing the wheel, the
rim could hit the brake rotor/ceramic brake
rotor* and damage the rotor . Work carefully
and have a second person help you.
Never use the hexagonal socket in the handle
of the screwdriver to loosen or tighten the
wheel bolts.

> A pp lies to vehicles with cer amic brake rotors*: Use a sec­
o n d alignment p in* (sto re d in th e s pare w hee l well mold ­
in g) fo r the lower hole , fol low ing the descrip tion for the
fir st a lig nme nt pin .
264
-Pull the reversible blade from the screwdriv­
er before you use the hexagonal socket in
the handle to turn the wheel bolts.
- When mounting tires with
unidirectional
tread design
make sure the tread pattern is
pointed the right way¢
page 264.
-The wheel bolts should be clean and easy to
turn. Check for dirt and corrosion on the
mating surfaces of both the wheel and the
hub. Remove all dirt from these surfaces be­
fore remounting the wheel.
Tires with unidirectional tread design
Tires with unidirectional tread design mus t 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 with a tread pattern in­
tended for use in a specific direction, please note
the following:
- 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 incor­
rect direction, use the spare tire only tempora­
rily since the tire will not be able to achieve its
optimum performance characteristics with re­
gard to aquaplaning, noise and wear.
- We recommend that you pay particular atten ­
tion to this fact during wet weather and that
you adjust your speed to match road condi­ tions.
- Replace the flat tire with a new one and have it
installed on your vehicle as soon as possible to
restore the handling advantages of a unidirec­
tional tire.
Notes on wheel changing
Please read the information¢ page 243 if you
are going to use a spare tire which is different
from the tires on your vehicle.
