Wheels
and a special procedure. You must not repair or
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 -
cation, refer to ¢
page 229, 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 217.
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
222
-
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 .

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 ..,.
