Manual Operation of Power Liftgate
With the power liftgate disabled and all of the doors
unlocked, the liftgate can be manually opened and
closed.
To open the liftgate, press the touchpad on the handle
on the outside of the liftgate, and lift the gate open.
To close the liftgate, use the pull cup to lower the liftgate
and close. The liftgate latch will power close. Always
close the liftgate before driving.
To change the liftgate to
manual operation, press
the switch on the center
console to the OFF
position.
If the RKE button or the power close button on the
liftgate is pressed while power operation is disabled,
the lights will flash three times, but the liftgate will
not move.
It is not recommended that you drive with the liftgate
open, however, if you must drive with the liftgate open,
the liftgate should be set to manual operation by
pressing the OFF switch on the center console.
The liftgate has an electric latch. If the battery is
disconnected or has low voltage, the liftgate will not
open. The liftgate will resume operation when the battery
is reconnected and charged.
If the battery is properly connected with adequate
voltage, the switch is not disabled, and the liftgate
still will not function, your vehicle should be taken
to a dealer/retailer for service.
