liftgate. Engine exhaust contains
carbon monoxide (CO) which
cannot be seen or smelled. It can

. Fully open the air outlets on
or under the instrument
panel.

.Presslon the bottom edge of
the liftgate next to the latch to
close.
Press any liftgate button, the touch
pad, or
bon the RKE transmitter
while the liftgate is moving to stop it.
Pressing any liftgate button or
pressing
btwice quickly on the
RKE transmitter restarts the
operation in the reverse direction.
Pressing the touch pad on the
liftgate handle will restart the
motion, but only in the opening
direction.
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 in extremely
low temperatures, or after repeated
power cycling over a short period of time. If this occurs, the liftgate can
still be operated manually. Select
OFF on the liftgate switch.
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. 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 poweropening 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
prevents the liftgate from completely
closing, the horn will sound as an
alert that the liftgate did not close.
