the tire man ufactur er's suggested tire ro ta­
tion intervals . Please remember the follow­
ing:
- Tire rotation in tervals may differ from the
veh icle servi ce inte rv al s o utli ned in your
Ma intenance and Warranty Boo klet.
- The longer one tire is used in one lo cation
on t he veh icle, the more it wears a t cer tain
points ; the re fore, we recommend that you
follow the tire man ufact urer's suggested
tire rotation intervals .
- Vehi cles w ith front-wheel dr ive experience

.8, WARNING
Sudden tire failure can lead to loss of con­
trol, a crash and serious personal injury!
- Never drive a veh icle when the tread on
any tire is worn down to the wear indica­
tors.
- Worn tires are a safety hazard, they do not grip well on wet roads and increase
your risk of "hydrop lan ing" and loss of
control.
- Always keep chemicals that can cause
tire damage, such as grease, oil, gasoline
and brake fluid away from tires.
- Tires age even if they are not being used
and can fail suddenly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then with special care and at lower
speeds.
- Never mount used tires on your vehicle if
you are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to s udden tire failure
and loss of vehicle control.
New tires and replacing tires and wheels
New tires and wheels have to be broken in .
