GENERAL INFORMATION

Models
'07 Highlander

INTRODUCTION:
The Highlander is equipped with an Indirect Tire Pressure Warning System (TPWS).

To operate the Tire Pressure Warning System under normal conditions, the TPWS ECU must be initialized with the tires at the specified tire inflation pressure. For further information on the 2007 model year Highlander Indirect Tire Pressure Warning System, refer to ETAS: 2004 model year Highlander New Car Features Manual: Chassis and Drivetrain: Tire Pressure Warning System.

Tire pressure is set high at the assembly plant for transport and storage to prevent tire flat spots. Therefore, after adjusting all the tires to the standard air pressure, perform initialization of the TPWS ECU at your dealership prior to delivery.

APPLICABLE VEHICLES:
- 2007 model year Highlander vehicles.







WARRANTY INFORMATION:

INITIALIZATION PROCEDURE:











1. Adjust all tires to the standard air pressure.







2. Turn the ignition switch to the "ON" position with the vehicle stopped. Check that the low tire pressure warning light blinks (twice per second).







3. Press and hold the tire pressure warning reset switch for 3 seconds until the low tire pressure warning light blinks 3 times in 6 seconds (once ever two seconds). After that, make sure the tire pressure warning light goes off.

NOTE:
If the low tire pressure warning light doesn't blink, release the tire pressure warning reset switch and press it again.

REFERENCE:
While TPWS initialization is in progress, the tire pressure is not being monitored.
Please explain to the customer during vehicle delivery that initialization of tire pressure warning system will be completed after driving the vehicle for 30 to 60 minutes and that the tire pressure is not monitored before the completion of the initialization.

NOTE:
If the low tire pressure warning light begins to blink (2 times per second) while driving, repeat the process above in Step 2.
