The Tire Pressure Monitor can alert you about low tire pressure, but it does not replace normal monthly tire maintenance. It is the driver's responsibility to maintain correct tire pressures. See Tire Pressure Monitor System on page 6‑83 and Tire Pressure Monitor Operation on page 6‑84. 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 6‑20. 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.
