Tire Pressure Monitor System RECALIBRATION
CAUTION:
DO NOT recalibrate TPM system until all problems are fixed and tire pressure in all 4 tires has been adjusted. If recalibration is done when tire pressures are incorrect, TPM system will not work properly and may not set an alert when a tire pressure is low or high.
CAUTION:
DO NOT push the reset switch without adjusting tire inflation pressure. Otherwise, the low tire pressure warning light may not come on even if the tire pressure is low, or it may come on when the tire inflation pressure is actually normal. If you push the reset switch while the vehicle is moving, initialization is not performed.
- Set the tire pressure of all wheels to pressure specified on the tire and loading information label.
- With the vehicle stopped and parking brake applied, turn the ignition switch to the ON position.
- Press and hold the tire pressure warning reset switch until the tire pressure warning light blinks 3 times at one-second intervals. See Fig 1.NOTE: If the tire pressure warning light does not blink, perform the initialization again. If light still does not blink, there is a problem in the TPM system. See appropriate manufacturer service information.
- Drive the vehicle at 19 mph (30 km/h) or more to complete the initialization (it takes about one hour). Vehicle should be driven under the following conditions:
- The vehicle speed is between 31-62 mph (50-100 km/h).
- The roads are dry, smooth and straight.
- The number of passengers is 1 or 2 (including driver).
- To verify the system has been initialized, check the length of time the tire pressure warning light is on after turning the ignition switch to the ON position. Light will stay on for 3 seconds if system is initialized, or 4 seconds if system is not initialized.
