WARNING (Continued)
. Under inflated tires pose the
same danger as overloaded
tires. The resulting crash
could cause serious injury.
Check all tires frequently to
maintain the recommended
pressure. Tire pressure
should be checked when your
tires are cold.
. Over inflated tires are more
likely to be cut, punctured,
or broken by a sudden
impact — such as when you
hit a pothole. Keep tires at
the recommended pressure.
. Worn or old tires can cause a
crash. If your tread is badly
worn, replace them.
. Replace any tires that have
been damaged by impacts
with potholes, curbs, etc.

WARNING (Continued)
. Improperly repaired tires can
cause a crash. Only your
dealer or an authorized tire
service center should repair,
replace, dismount, and mount
the tires.
. Do not spin the tires in
excess of 55 km/h (35 mph)
on slippery surfaces such
as snow, mud, ice, etc.
Excessive spinning may
cause the tires to explode.

Winter Tires
If you expect to drive on snow or ice
covered roads often, you may want
to get winter tires for your vehicle.
All season tires provide good overall
performance on most surfaces but
they may not offer the traction you
would like or the same level of
performance as winter tires on snow
or ice covered roads.
Winter tires, in general, are
designed for increased traction on
snow and ice covered roads. With
winter tires, there may be decreased
dry road traction, increased road
noise, and shorter tread life. After
switching to winter tires, be alert for
changes in vehicle handling and
braking.
See your dealer for details
regarding winter tire availability and
proper tire selection. Also, see
Buying New Tires on page 10‑54.
