the tires to the recommended
pressure shown on the Tire and
Loading Information label. See
Vehicle Load Limits0205. 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 0323.
Engine Oil Life System
The engine oil life system calculates
engine oil life based on vehicle use
and displays a DIC message when
it is necessary to change the engine

should be reset to 100% only
following an oil change. Resetting the Oil Life System
To reset the engine oil life system:
1. Display REMAINING OIL LIFE on the DIC. See Driver

2. Press and hold the
Vbutton on
the DIC. 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 REMAINING OIL LIFE on the DIC. If the display
shows 100%, the system is
