Press V on the DIC controls and hold down for a few seconds to clear the CHANGE ENGINE OIL SOON message and reset the oil life at 100%. Be careful not to reset the oil life display accidentally at any time other than after the oil is changed. It cannot be reset accurately until the next oil change. See Engine Oil Life System on page 10-13. 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. See Tire Pressure Monitor System on page 10-50.

Avoid idling the engine for long periods of time. When road and weather conditions are appropriate, use cruise control. . . .
