Press the touch pad on the tailgate
handle.
A chime sounds and the taillamps flash
during the closing operation. If the warning
chime is not functioning, the tailgate will
not power close. Power opening is still
enabled. See your dealer for service.
The power tailgate may be temporarily
disabled after repeated power cycling over a
short period of time. If this occurs, the
tailgate can still be operated manually.
The vehicle must be in P (Park) to operate
the power tailgate. If the vehicle is shifted
out of P (Park) while the power function is
in progress, the tailgate will continue to
completion. If the vehicle is accelerated
while the tailgate is still closing, the tailgate
may stop and reverse direction. Make sure
the tailgate is closed and latched before
driving.
Lift-to-Close Operation
To close the tailgate using the lift-to-close
feature, lift the tailgate from the full-open
position to at least 10 cm (4 in) and hold it
momentarily. Then, the tailgate will start
closing automatically. If the tailgate is lifted
more than halfway between open and close,
then it will not close automatically.
Obstacle Detection
If the tailgate encounters an obstacle during
a power open cycle, it will stop on the
obstacle. After removing the obstruction, the
tailgate can be allowed to open. If the
tailgate encounters an obstacle during the
closing cycle, it will stop and reverse to
full open.
If the tailgate encounters multiple obstacles,
the power function will deactivate. After
removing the obstructions, manually close
the tailgate to resume normal power
operation.
Manual Operation
The tailgate can be manually closed from
the full-open position when the tailgate is
lifted in a continuous motion. If the tailgate
motion is stopped between the full-open
and half-closed positions, the lift-to-close
feature can engage and power close the
tailgate. If the touch pad is pressed during
power operation, the tailgate will stop and
allow manual operation. The tailgate must
be held after stopping, or it will continue
to open.
