CHECK ANTI-PINCH FUNCTION
1. Fully open the door window.
2. Place a piece of wood near fully closed position.
3. Close door glass completely with AUTO-UP.
• Check that glass lowers for approximately 150 mm or 2 seconds without pinching piece of wood and stops.
• Check that glass does not rise when operating the power window main switch while lowering.
CAUTION:
• Do not check with hands and other part of body because they may be pinched. Do not get pinched.
• Check that AUTO-UP operates before inspectio n when system initialization is performed.
• It may switch to fail-safe mode if open/close oper ation is performed continuously. Perform initial set-
ting in that situ ation. Refer to PWC-11, "Fail-safe"
