Note: In case of operation in extreme cold -40° F (-40° C), or on
extreme inclines, manual operation of the liftgate is suggested.
Obstacle detection
The power liftgate system is equipped with an obstacle detection feature.
If the power liftgate is closing, the system is designed to reverse to full
open when it encounters a solid obstacle. A three second chime is also
sounded when an obstacle is detected. Once the obstacle is removed, the
liftgate can be closed under power.
If the power liftgate is opening, the system is designed to stop when it
encounters a solid obstacle. A chime will sound for three seconds while
the obstacle is present.
Resetting the power liftgate:
The power liftgate may not operate under these conditions. If any of
these conditions occur, the power liftgate must be reset.
• a low voltage or dead battery
• disconnected battery
• the liftgate is manually closed and left ajar (unlatched)
To reset the power liftgate:
1. Disconnect the battery for 20 seconds then, reconnect the battery.
2. Manually close and fully latch the liftgate.
3. Power open the liftgate by using the remote entry transmitter or
instrument panel button.
Note: If the power liftgate system is turned <OFF> in the message
center, the system cannot be activated with the outside release handle or
rear cargo area control button. The system will need to be turned <ON>
to resume operation with the outside release handle or rear cargo area
control button. The Power Liftgate is still operational through the use of
the Remote entry transmitter and IP button when the Power Liftgate is
turned off in the Message center.
Liftgate ajar signal
If the liftgate or liftgate glass are not fully latched, you will receive a
“LIFTGATE or LIFTGLASS AJAR” message on the instrument panel. If
you see this message, check both the liftgate glass and liftgate door to
ensure they are fully latched.
