Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/t ighten
eas ily .
Rims
Rims with a bolted rim ring* or with bolted wheel
covers* consist of mu ltip le pieces. These compo­
nents were bolted together using special bolts
Wh eel s
and a special procedu re. Yo u must not repair or
disassemb le them
~ &. .
A WARNING
-Wheel bo lts that are tightened or repaired in-
correct ly can become loose and resu lt in loss
of vehicle contro l, wh ich increases the risk of
an accident. For the cor rect tighten ing specifi­
cation,
see¢ page 366, Finishing .
-Always keep the wheel bolts and the
threads in the wheel hub clean and free of
g rease .
- Only use wheel bolts that fit the rim.
- Always have damaged rims repaired by an
author ized Audi dealer or author ized Audi
Serv ice Facility . Never repair or disassemb le
rims yourself, because th is increases the r isk
of an a cc ident.
Winter tires
Winter tires signific ant ly imp rove the vehicle 's
handling when dr iv ing in winter conditions . B e­
ca use of their construct ion (w idth, compound,
tread pattern), summer tires provide less t rac ­
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
author ized 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 344 .
The effectiveness of winter tires is reduced great­
ly when the tread is wo rn down to a depth of
0.16 in (4 mm). The cha racteristics of w inte r
ti res a lso decrease g reatly as the ti re ages, re­
gardless of the rema in ing t read.
A WARNING
-
- Never drive fas ter than the max imum per­
mitted speed for your tires . This could cause
the tires to heat up too much. This increases

could slip and cause an injury if it does not
have sufficient hold on the vehicle.
- To reduce the risk of an accident, never start
the engine when the vehicle is raised.
- To reduce the risk of injury, support the ve­
hicle securely with suitable stands if work is
to be performed underneath the vehicle.
- To help prevent injury to yourself and your
passengers:
- Do not raise the vehicle until you are sure the jack* is securely engaged.
- Passengers must not remain in the vehicle when it is jacked up.
- Make sure that passengers wait in a safe
place away from the vehicle and well away
from the road and traffic.
- Make sure jack position is correct, adjust as necessary and then continue to raise
the jack*.
- If work has to be done under the vehicle, ensure that it is safely supported on suita­
ble stands
-risk of injury!
- Never start the engine when the vehicle is on the jack*
-risk of accident!

~fig. 287 and place it on a
clean surface.
.,. Install the alignment pin (from the vehicle tool
kit) by hand into the empty
hole ~ fig. 288.

.,. Remove the alignment pin and also tighten the
remai ning wheel bolt.
.,. Carefully lower the vehicle using the vehicle
jack*.
.,. Tighten the wheel bolts in a diagonal pattern

wheel and hub . Contaminants on these surfaces
must be removed before installing the wheel.
A WARNING
