The tire inflation monitor (TIM) system alerts the driver when a change in the tire pressures exists. The system only detects a low pressure condition while the vehicle is being driven. Once a low tire pressure condition is detected, the system informs the driver whenever the ignition is ON.

The CHECK TIRE PRESSURES message appears on the DIC if the tire pressure in one or more tires becomes at least 69 kPa (10 psi) lower or higher than the other tires and the ignition is ON. The message does not appear if the system is not calibrated properly. The system does not inform the driver which tire is low. To clear this message, set the tire pressures in all four tires to the proper pressures and perform the system reset procedure.
