Wheels
and a special procedure. You must not repair or
disassemble them > A\.
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 272, Finishing.
~ 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 significantly improve the vehicle's
handling when driving in winter conditions. Be-
cause of their construction (width, compound,
tread pattern), summer tires provide less traction
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 @ A\ in
General information on page 235. An author-
ized Audi dealer or authorized Audi Service Fa-
cility can inform you about the maximum per-
mitted speed for your tires.
» Check the tire pressure after installing wheels
> page 246.
The effectiveness of winter tires is reduced great-
ly when the tread is worn down to a depth of
0.16 in (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages, re-
gardless of the remaining tread.
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.
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 4, symbol may be per-
mitted.
Snow chains improve both driving and braking in
winter road conditions.
» Only install snow chains on the front wheels.
» 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
(50 km/h). Observe the local regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authorized 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 0.40 inch (10.5 mm) in height, includ-
ing the chain lock.
You must remove the snow chains on roads with-
out snow. Otherwise, you could impair driving
ability and damage the tires.
Using incorrect snow chains or installing snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an act
dent.
Snow chains can damage the rims and wheel
covers* if the chains come into direct contact
with them. Remove the wheel covers* first.
Use coated snow chains.
