When rotating your tires, always use the correct
rotation pattern shown here.
Do not include the compact spare tire in your tire
rotation.
After the tires have been rotated, adjust the front
and rear inflation pressures as shown on the Tire
and Loading Information label. See Inflation - Tire
Pressure on page 392 and Loading Your Vehicle
on page 307.
Reset the Tire Pressure Monitor System. See
"TPMS Sensor Identification Codes" under
Tire Pressure Monitor System on page 394.
Make certain that all wheel nuts are properly
tightened. See "Wheel Nut Torque" under
Capacities and Specifications on page 438.
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 408.
