Tire Pressure Monitor
This vehicle may have a Tire Pressure Monitor
System (TPMS).
The warning light will remain on until the tire pressure
is corrected. The proper tire pressures for your
vehicle are listed on the Tire and Loading Information
label located on the driver side center pillar (B pillar).
See Loading the Vehicle on page 5-20.
You may notice during cooler conditions that the low tire
pressure warning light will appear when the vehicle is first
started and then turn off as you drive. This may be an
early indicator that your tire pressures are getting low
and the tires need to be inflated to the proper pressure.
Note: 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 6-60 and
Tire Pressure Monitor Operation on page 6-62.

The Tire Pressure Monitor
alerts you when a
significant reduction in
pressure occurs in one or
more of the vehicle's tires
by illuminating the low tire
pressure warning light on
the instrument cluster.
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 oil and filter.
The oil life system should be reset to 100% only
following an oil change.
Resetting the Oil Life System
1. Display the OIL LIFE REMAINING on the DIC.
2. Press and hold the SET/RESET button on the DIC
for more than five seconds. The oil life will change
to 100%.
See Engine Oil Life System on page 6-18.
