an acc ident .
Winter tires
Winte r tires s ignificantly improve the vehicle's
handling when d riving 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.
"'Use w inte r t ires on all four wheels.
"' Only use winter t ires that a re approved for your
vehicle.
"' Please note that t he maximum permitted
speed may be lower with winter tires
¢
&, .
Wh e el s
Your authorized Audi 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 cause
the t ires to heat up too mu ch. This increases
the risk of an accident because it can cause
the t ire to burst.
- Always adapt your driving t o t he 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 at 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.

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

"' Only install snow chains on the
front
wheels.
"' Check and correct the seating of the snow
chains if necessary after driving a few feet. Fol-
low the instructions from the manufacturer.
