Tire Pressure Monitor This vehicle may have a Tire Pressure Monitor System (TPMS). 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. 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 5‑23. 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 6‑62 and Tire Pressure Monitor Operation on page 6‑64. Tire Sealant and Compressor Kit This vehicle may come with a jack and spare tire or a tire sealant and compressor kit. The kit can be used to seal small punctures in the tread area of the tire. See Tire Sealant and Compressor Kit (Without Selector Switch) on page 6‑78 or Tire Sealant and Compressor Kit (With Selector Switch) on page 6‑87 for complete operating information. 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. 1-21
