the tires to the recommended
pressure shown on the Tire and
Loading Information label. See
Vehicle Load Limits 0 269. 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.

System 0 409.

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) 0 148 or Driver
Information Center (DIC)
(Uplevel) 0 150. If the vehicle
does not have DIC buttons, the
vehicle must be in P (Park) to
access this display.
2. Press and hold the
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%.
The oil life system can also be reset
as follows:
1. Turn the ignition to ON/RUN
with the engine off.
2. Fully press the accelerator
pedal slowly three times within
five seconds.
3. Display OIL LIFE REMAINING
on the DIC. If the display
shows 100%, the system is
reset.
See Engine Oil Life System 0 366.
