Two-step Down Function
• If a switch is lightly pushed (manual open operation) when the window is completely closed, the window lowers
a set distance. (Initial setting is approx. 30 mm {1.2 in}.)
• If the manual open operation is performed with the two-step down function enabled, the window will always stop
momentarily. (This is not a malfunction.)
• The set distance the window goes down can be changed. (Within a range of approx. 20-100 mm {0.79-3.9 in}.)
• The two-step down function can be disabled. (Initial setting is enabled)
• If the operation of the auto open/close, manual close or window obstruction is detected during two-step down
function operation, these other operations are given priority.
• Does not function during IG OFF Timer operation.
Ignition Off Timer Function
• Allows operation of the driver's power window for approx. 40 s after the ignition switch has been turned from the
ACC to the LOCK position.However, when the front door is opened/closed during IG OFF timer, the function
stops.

malfunction in the pulse signal (Hall IC).
