If REMAINING OIL LIFE 99% is
displayed, that means 99% of the

When the remaining oil life is low,
the CHANGE ENGINE OIL SOON
message will appear on the display. See
Engine Oil Messages on
page 5‑35. The oil should changed
as soon as possible. See Engine

Do not include the compact
spare tire in the tire rotation.
After the tires have been
rotated, adjust the front and
rear inflation pressures as
shown on the Tire and Loading
Information label. SeeTire
Pressure on page 10‑54
and Vehicle Load Limits on
page 9‑12.
Reset the Tire Pressure Monitor
System. See Tire Pressure
Monitor Operation on
page 10‑57. Make certain that all wheel
nuts are properly tightened.
See
“Wheel Nut Torque” under
Capacities and Specifications on
page 12‑2.
{WARNING
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
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle.
In an emergency, 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 If a Tire
Goes Flat on page 10‑70.
Lightly coat the center of the
wheel hub with wheel bearing
grease after a wheel change
or tire rotation to prevent
corrosion or rust build-up.
Do not get grease on the flat
wheel mounting surface or
on the wheel nuts or bolts.
