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)

and set the fan speed to the
highest setting. See
“Climate Control Systems”
in the Index.

Obstacle Detection Features
If the liftgate encounters an obstacle
during a power open or close cycle,
a warning chime may sound and 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
sensor, the liftgate will reversedirection and open fully. The liftgate
will remain open until it is activated
again or closed manually.
