CAUTION: HANDLE WITH CARE.
To ensure our customers receive all components with full integrity, we pack the motors separate from their linkage
assemblies. This requires that the installer position and fasten the motor before continuing with the install. Please
follow the instructions below and handle the assembly carefully.
CAUTION: Dropping the assembly or any excessive impact MAY cause damage to the motor.
Instructions:
1. Position the gear cover in place as shown if not already in place.
2. Seat motor into position on the three mounting bosses. This may require an adjustment of the gear by moving
the swing arms.
3. After seating into place, fasten the motor with the three motor mount screws with 4mm Hex Head. Tighten
screws to 36 in-lbs (4N-m). Do not over torque.

CORRECT OPERATION OF LIGHTS: All four lamps will illuminate upon opening any door of vehicle.
Lamps will stay on until restowing of both Power Steps or until 5 minutes has expired with the doors open.
When the lights timeout after 5 minutes, they can be reillumintated by closing and opening any door of
vehicle.
FINAL SYSTEM CHECK
Check that all doors activate the PowerStep and the LED lights work when doors open and close.
NORMAL OPERATION: When the doors open, PowerStep automatically deploys from under the vehicle.
When the doors are closed, PowerStep will automatically return to the stowed/retracted position. Note that
there is a 2-second delay before the PowerStep returns to the stowed/retracted position.
Check that all doors activate the Power Step and the LED Lights work when doors open and
close. Reinstall any remaining trim panels.
