type tires. Rotation will increase tread life, help to main-
tain mud, snow, and wet traction levels and contribute to
a smooth, quiet ride.
Follow the recommended tire rotation frequency for your
type of driving found in the “Maintenance Schedules”
Section of this manual. More frequent rotation is permis-
sible, if desired. The reason(s) for any rapid or unusual
wear should be corrected before rotating. The suggested
rotation method is the “forward-cross” shown in the
diagram below.
TIRE PRESSURE MONITORING SYSTEM (TPMS)
— IF EQUIPPED
• The Tire Pressure Monitor System (TPMS) will warn
the driver of a low tire pressure based on the vehicle
recommended cold placard pressure.
• The tire pressure will vary with temperature by about
1 psi (6.9 kPa) for every 12°F (6.5°C). This means that
when the outside temperature decreases, the tire pres-
sure will decrease. Tire pressure should always be set
based on “cold inflation tire pressure”. This is defined
as the tire pressure after the vehicle has not been
driven for at least three hours, or driven less than 1 mi
(1 km) after a three hour period. The cold tire inflation
pressure must not exceed the maximum inflation
pressure molded into the tire sidewall. Refer to “Tires

on how to properly inflate the vehicle’s tires. The tire
