The Tire Pressure Monitor can alert you about low tire
pressure, but it does not replace normal monthly tire
maintenance. It is the drivers responsibility to maintain
correct tire pressures.
See Tire Pressure Monitor System
on page 673
and
Tire Pressure Monitor Operation on page 675.
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 on most vehicles:
1. Display the OIL LIFE REMAINING on the DIC.
If the vehicle does not have DIC buttons, the
vehicle must be in P (Park) to access this display.
2. Press and hold the SET/RESET button on the DIC,
or the trip odometer reset stem if the vehicle does
not have DIC buttons, for more than five seconds.
The oil life will change to 100%.
On all vehicles, the Engine Oil Life System can 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 the OIL LIFE REMAINING on the DIC.
If the display shows 100%, the system is reset.
See Engine Oil Life System on page 620.
