liftgate or trunk/hatch open,
or with any objects that pass
through the seal between the
body and the trunk/hatch or

carbon monoxide (CO) which
cannot be seen or smelled. It can
cause unconsciousness and even
death.
If the vehicle must be driven with
the liftgate or trunk/hatch open:
. Close all of the windows.
. Fully open the air outlets on
or under the instrument
panel.
(Continued)
Warning (Continued)
.Adjust the climate control
system to a setting that
brings in only outside air
and set the fan speed to the
highest setting. See
“Climate Control Systems”
in the Index.
. If the vehicle is equipped
with a power liftgate, disable
the power liftgate function.
See Engine Exhaust 0209.

Power Liftgate Operation
{Warning
You or others could be injured if
caught in the path of the power
liftgate. Make sure there is no one
in the way of the liftgate as it is
opening and closing.
Caution
Driving with an open and
unsecured liftgate may result in
damage to the power liftgate
components.
The switch is on the driver door. The
vehicle must be in P (Park).
The modes are:
.MAX: Opens to maximum
height.
. 3/4: Opens to a reduced height
that can be set from 3/4 to fully
open. Use to prevent the liftgate
from opening into overhead
obstructions such as a garage
door or roof-mounted cargo. The
liftgate can be manually opened
all the way.
. OFF: Opens manually only. To power open or close the liftgate,
select MAX or 3/4 mode.

.Presslon the bottom of the
liftgate to the left of the latch to
close.
Press any liftgate button or the
touch pad while the liftgate is
moving to stop it. Pressing again
restarts the operation in the reverse
direction. The touch pad on the
underside of the liftgate handle
cannot be used to close the liftgate.
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
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 this

direction and open fully. The liftgate
will remain open until it is activated
again or closed manually.

liftgate.
