Falling Liftgate Detection
If the power liftgate
automatically closes after a
power opening cycle, it
indicates that the system is
reacting to excess weight on
the liftgate or a possible
support strut failure.
A repetitive chime will sound
while the falling liftgate
detection feature is operating.
Remove any excess weight.
If the liftgate continues to
automatically close after
opening, see your dealer for
service before using the
power liftgate.
Interfering with the power
liftgate motion or manually
closing the liftgate too quickly
after power opening may
resemble a support strut
failure. This could also activate
the falling liftgate detection
feature. Allow the liftgate to
complete its operation and
wait a few seconds before
manually closing the liftgate.Obstacle Detection
Features
If the liftgate encounters an
obstacle during a power open
or close cycle, the liftgate will
automatically reverse direction
and move a short distance
away from the obstacle. After
removing the obstruction, the
power liftgate operation can
be used again. If the liftgate
encounters multiple obstacles
on the same power cycle, the
power function will deactivate.
After removing the
obstructions, manually close
the liftgate. This will allow
normal power operation
functions to resume.
If the vehicle is locked while
the liftgate is closing, and an
obstacle is encountered that
prevents the liftgate from
completely closing, the horn
will sound as an alert that the
liftgate did not close.
Setting the 3/4 Mode
To change the position the
liftgate stops at when
opening:1. Select MAX or 3/4 mode and power open the
liftgate.
2. Stop the liftgate movement at the desired
height by pressing any
liftgate button. Manually
adjust the liftgate position
if needed.
3. Press and hold
lnext to
the pull cup on the bottom
of the liftgate until the turn
signals flash and a beep
sounds. This indicates the
setting has been recorded.
The liftgate cannot be set
below a minimum
programmable height. If there
is no light flash or sound, then
the height adjustment may be
too low.
