2015 Legacy and Outback
Warning: Keep away from the closing area of the rear gate (PRG). The outer edge of the rear
gate (PRG) beyond the touch sensor cannot detect solid objects and will not trigger a
safety maneuver until the amperage of the rear gate (PRG) exceeds a pre-established
specification.
The 2015 Outback PRG is classified as an Arm Lift system that receives mechanical power from
the motor through a set of stacked reduction and drive gears. A spring is used to assist with the
initial movement of the gate (opening or closing). Gate operation of the Forester Spindle Drive
PRG is accomplished with a threaded drive block and rotating threaded drive rod.
Arm Lift PRG
The PRG of the Outback can never be separated from the reduction drive gears. This type of
system eliminates the need for a motor clutch and half stop solenoid. The combined gear ratio
and force from the gate struts will hold the gate in a set position.
The Forester PRG is equipped with an electric clutch to disengage the Spindle Drive system
from the reduction gears and motor. A Manual Release lever allowed for a fail-safe mechanical
disengagement of the moving parts that can be utilized if an electrical or mechanical problem
prevented the gate from opening.
PRG Gear Set
Constant mesh Arm Lift PRGs cannot separate the gate lifting mechanism from the drive system
which prevents any type of fail-safe mechanical release. Removing the lift arm is the only way to
separate the gate from the PRG assembly.
