T i re s and w heel s
equip all four wheels on your vehicle with cor-
rectly fitted winter tires or all-season tires,
when winter road conditions are expected .
This also improves the vehicle's braking per-
formance and reduces stopping distances.
Summer tires provide less grip on ice and
snow.
W inter t ires (snow t ires) must always be fitted
on all four whee ls.
Compat ible tire pressure mo nitor ing sensors
must be installed on all fo ur winter tires for
the tire pressure monitoring system t o func-
tion proper ly
i=;, p oge

Ask your autho rized Audi dealer or qualified
wo rkshop fo r permitted winter tir e sizes. Use
on ly radia l w inte r tires .
W inter t ires lose the ir effectiveness when the
tread is worn down to a depth of 0.157 inch
(4 mm) .
Only drive with wi nter tires under winter con-
ditions . Summer tires hand le better when
there is no snow or ice on the roads and the
temperature is above 45 °F (7 °C).
Please always remembe r that w inte r t ires may
have a lower speed rating than the t ires origi-
nally installed on your veh icle at the t ime it
was manufactured. Please see

A
WARNING
Winter tires have maximum speed limits
that may be lower than your vehicle's max-
im um speed . Always know the maxim um
speed before driving off. Never drive faster
than the speed permitted for your specific
w inte r t ires. This will cause damage to the
tires leading to an accident and serious
personal inj ury to you and yo ur passen-
gers.
A
WARNING
Driving faster than the maximum speed
for which the winter tires on your veh icle
were designed can cause t ire failure in-
cluding a blowout and sudden deflation,
loss of cont rol, crashes and serious per-
sonal injuries. Have wo rn or damaged ti res
replaced immedia t ely.
- W inte r ti res have maxim um speed rating
tha t may be lower than your vehicle 's
maximum speed.
- Never drive fas t er t han the speed for
which the win t er or othe r ti res installed
on your vehicle are rated.
A
WARNING
~
Always adju st your driving to the road and
traffic condit ions. Never let the good ac-
celeration of the winter tires and all -wheel
drive tempt you into taking extra risks. Al-
ways remember:
- When braking, an all-wheel drive veh icle
handles in the same way as a front drive
veh icle.
- Drive carefully and reduce your speed on
icy and slippery roads, even w inter t ires
cannot help under black ice conditions .
~
For the sake of the environment
Use summer tires when weather condi -
tions permit. They are qu ieter, do not wear
as quickly and reduce fuel consumpt ion.
Snow chains
-
Snow chains may be fitted only to the rear
whee ls, and only to certa in tire sizes. Ask your
autho rized Audi dealer on whi ch t ire sizes
snow chains can be used.
The snow chains must have low-p rofile links
and must not be t hicker than 0.53 inch
(13 .5 mm), including the lock.
Remove wheel center covers before putt ing
snow chains on your vehicle

For safety
reasons cover caps must then be f itted over
