Caution
Manually forcing the liftgate to
open or close during a power
cycle can damage the vehicle.
Allow the power cycle to
complete.
The power liftgate may be
temporarily disabled under extreme
low temperatures, or after repeated
power cycling over a short period of
time. If this occurs, the liftgate can
still be operated manually.
If the vehicle is shifted out of
P (Park) while the power function is
in progress, the liftgate will continue
to completion. If the vehicle is
accelerated before the liftgate has
completed moving, the liftgate may
stop or reverse direction. Check for
Driver Information Center (DIC)
messages and make sure the
liftgate is closed and latched before
driving. 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 which 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.
Pinch sensors are on the side
edges of the liftgate. If an object is
caught between the liftgate and the
vehicle and presses against a
sensor, the liftgate will reverse
direction and open fully. The liftgate
will remain open until it is activated
again or closed manually.

Seats and Restraints 37
Head Restraints
The vehicle’s front seats have
adjustable head restraints in the
outboard seating positions.
{Warning
With head restraints that are not

there is a greater chance that
occupants will suffer a neck/
spinal injury in a crash. Do not
drive until the head restraints for
all occupants are installed and
adjusted properly.

restraints that fold down, always
return them to the full upright
position whenever an occupant is
seated in the seat.

top of the restraint is at the same
height as the top of the occupant's
head. This position reduces the
chance of a neck injury in a crash.
