Initializing Tire Pressure Monitor System

CAUTION: Set tire pressure within the specified range before initializing. DO NOT push the reset switch without adjusting tire inflation pressure of all tires (including the spare tire). 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.

NOTE: The system will need to be initialized when tires are rotated, replaced with tires of different pressures, or tire pressure sensor and/or tire pressure monitor ECU are replaced. Set tire pressure within the specified range before initializing. When a tire pressure sensor and/or tire pressure monitor ECU are replaced, the sensor ID must be memorized (registered) by the tire pressure monitor ECU prior to system initialization. See TIRE PRESSURE SENSOR REGISTRATION .

During initialization, the tire pressure sensor measures the inflation pressure of the tires, and registers the signals that are transmitted into the tire pressure monitor ECU at a frequency of one per minute. If initialization is performed, the existing tire positions will be cleared, but will be automatically identified when the vehicle is driven at 40 km/h (25 mph) or more for 10 minutes or more (Tire Inflation Pressure Display Function).

Initialization is normally completed within a few minutes. However, it may take 10 minutes or more until the tire pressure of the tire inflation pressure display function is shown (Tire Inflation Pressure Display Function). The initialization process is canceled if the ignition switch is turned to OFF position prior to the completion of initialization. To restart initialization, the tire pressure warning reset switch must be pressed again.

NOTE: If the engine switch is turned off during initialization, it is not necessary to restart the initialization procedure from the beginning as it will begin automatically when the engine switch is turned back to IGNITION ON mode.

CAUTION: During TEST MODE (sensor check mode), the system will not change to initialization mode even if the tire pressure warning reset switch is pushed.

Park the vehicle in a safe place and stop the engine for 20 minutes or more.
Set tires to the specified (cold) pressures as indicated on the tire and loading information label.
Start the engine.
Select Settings Display (gear icon) on the multi-information display using the meter control switches on the steering wheel. See Fig 1
Select Vehicle Information (7-inch display) or Vehicle Settings (4.2-inch dispaly) and then press and hold OK.
Select "TPWS" and then press OK.
Select "Set Pressure" then press and hold OK until the tire pressure warning light blinks 3 times.
NOTE: A message will then be displayed on the multi-information display. "---" will be displayed on the multi-information display for the inflation pressure of each tire while initialization is being performed.
Drive straight (with occasional left and right turns) at approximately 25 mph (40 km/h) or more for approximately 10 to 30 minutes.
Initialization is complete when the position of each tire is determined and the inflation pressure of each tire is displayed on the multi-information display.
NOTE: Initialization may take longer than approximately 1 hour in certain situations, such as when the vehicle is stopped for a long time at traffic lights, etc.
