1. When both of the following conditions are fulfilled, check that the door glasses, the back door glass and the roof glass can be operated even after the ignition switch is turned OFF:
   • Within 45 seconds after the ignition switch is turned OFF
   • The driver side door is closed

HINT:

The jam protection function prevents any part of your body from getting caught by accident between the door frame and the door glass during power window operation.

1. Check that the door glass goes down by approximately 50 mm (2.0 in.) right when something gets caught between the door frame and door glass during power window operation. However, when the opening amount between the vehicle body and the door glass is less than 200 mm (7.9 in.), the door glass keeps going down until the opening amount reaches 200 mm (7.9 in.) and stops there.

Operative condition: 

• AUTO UP
• AUTO UP operation after the ignition switch OFF
• MANUAL UP operation after the ignition switch OFF
