Lo/Hi Grade System
NOTE:
The Lo/Hi Grade TPM System is an Indirect TPMS. It does not use tire pressure sensors in each wheel. It uses the wheel speed sensors to determine tire inflation pressure.
In the following cases, system initialization must be performed so that the system operates normally:
- A tire pressure is adjusted
- A tire rotation is performed
- A tire or wheel is replaced
- The battery is replaced or completely discharged
- The warning light is illuminated
To initialize the TPMS:
- Park the car in a safe place and firmly apply the parking brake.
- Be sure the tires are cool, then adjust the tire pressure of all four (4) tires to the specified pressure indicated on the tire placard label located on the driver's door frame (door open).
- Place the ignition in the ON mode.
- While the vehicle is parked, press and hold the TPMS system set switch and verify that the warning light in the instrument cluster flashes twice and a beep sound is heard once.
