Tire Pressure Monitor
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The low tire pressure warning light
alerts to a significant loss in
pressure of one of the vehicle's
tires. If the warning light comes on,
stop as soon as possible and inflate
the tires to the recommended
pressure shown on the Tire and
Loading Information label. See
Vehicle Load Limits on page 9-15.
The warning light will remain on until
the tire pressure is corrected.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
may be an early indicator that the
tire pressures are getting low and
the tires need to be inflated to the
proper pressure.
The TPMS does not replace normal
monthly tire maintenance. Maintain
the correct tire pressures.
See Tire Pressure Monitor System
on page 10-64.Engine Oil Life System
The engine oil life system calculates
engine oil life based on vehicle use
and, on most vehicles, displays a
DIC message when it is necessary
to change the engine oil and filter.
The oil life system should be reset
to 100% only following an oil
change.
Resetting the Oil Life System
To reset the engine oil life system:
1. Display OIL LIFE REMAINING
on the DIC. See Driver
Information Center (DIC) (Base
Level) on page 5-30 orDriver
Information Center (DIC)
(Uplevel) on page 5-32. If the
vehicle does not have DIC
buttons, the vehicle must be in
P (Park) to access this display.
2. Press and hold the
Vbutton on
the DIC, or the trip odometer
reset stem if the vehicle does
not have DIC buttons, for
several seconds. The oil life will
change to 100%.

This indicates that one or more of
the tires are significantly
underinflated.
A Driver Information Center (DIC)
tire pressure message may also
display. See
Tire Messages on
page 5-43. Stop as soon as
