Inspection Mode

INSPECTION MODE

HINT:
- If the engine is warmed up and the battery is charged, the engine of RX400h will stop after the vehicle stops. Therefore, if the engine is required to run continuously even after the vehicle stops, such as for an ignition timing check, switch to the 4WD inspection mode.
- The RX400h is equipped with the 4WD system by which the rear wheels are electronically controlled by the motor, VSC system, and TRC system. Therefore, it is necessary to switch to the 2WD operation mode and cancel all of these systems when only the front wheels are required to be rotated on a chassis dynamometer.
