EXPLANATION OF COMPONENTS
This function facilitates the load-and-carry operation.
• When the travel speed is 12.5 km/h or higher, the gear speed is shifted down by one gear speed each time
the kickdown switch is pressed as F4, F3, and F2 in this order.
• When the kickdown switch is pressed during the torque converter lockup, the torque converter lockup is
canceled.
REMARK
• Even if the auto-kickdown is enabled, the downshift with this kickdown switch actuates.
• If the travel speed increases after a kickdown, the gear speed is shifted up automatically with the automatic
shift.
When the travel speed is 13 km/h or higher in 3rd gear speed, and 25 km/h or higher in 4th gear speed, the
gear speed is not shifted down to prevent the engine from overrunning even if the kickdown switch is press-
ed.
