disassemble them

A
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 t ightening specifi

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
W inter 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
q
.&,.
.
An
authori zed Audi dealer or authori zed Audi Serv-
ice Facility can inform you about the maximum
permitted speed for your tires
.
.,.
Check the
tire
pressure after install ing wheels
q
page 215.
The effectiveness of winter
tires
is
reduced
great-
ly when the
tread
is worn down to a depth of
0 .157
in (4 mm). The
characteristics
of winter
tires
also decrease
greatly as the tire
ages,
re-
gardless of
t
he remaining tread.
A
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
220
-
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 prov ide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fuel
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, only
winter tires w ith
the
~
symbol may be per-
mitted.
Snow chains
Snow
chains improve traction in the
snow.
.,.
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 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).
Snow chains
not
only improve
the
driving
in
win-
ter
road conditions,
but
also
the
braking
.
Use
of snow chains is only
permitted
with certa in
rim/tire
comb inat ions due
to technical
reasons.
Check
with
an
author ized Audi dealer or
author-
ized
Audi Service
Facility to
see if you may
use
snow chains.
Use
fine-mesh snow
chains.
They must not add
more
than 0.53
inch (13
.5
mm) in height,
includ-
ing
the chain
lock.
You must
remove
the chains when driving on
roads
that
are
free
of snow
.
When roads are free
