When rotating your tires, always use the correct
rotation pattern shown here.
After the tires have been rotated, adjust the front
and rear inflation pressures as shown on the
Tire and Loading Information label. See Loading
Your Vehicle on page 356, for an example of
the label and its location on your vehicle.
The Tire Pressure Monitor System (TPMS)
sensors will need to be reset after a tire rotation.
See "TPMS Sensor Identification Codes" under
Tire Pressure Monitor System on page 459.
Make certain that all wheel nuts are properly
tightened. See "Wheel Nut Torque" under
Capacities and Specifications on page 513.
CAUTION:
{
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after time. The wheel could
come off and cause an accident. When
you change a wheel, remove any rust or
dirt from places where the wheel attaches
to the vehicle. In an emergency, you can
use a cloth or a paper towel to do this;
but be sure to use a scraper or wire brush
later, if needed, to get all the rust or dirt
off. See Changing a Flat Tire on page 474.
