{WARNING
Unlocked doors can be
dangerous.
.Passengers, especially
children, can easily open
the doors and fall out of a
moving vehicle. When a door
is locked, the handle will not
open it. The chance of being
thrown out of the vehicle in
a crash is increased if the
doors are not locked. So, all
passengers should wear
safety belts properly and
the doors should be locked
whenever the vehicle is
driven.(Continued)
WARNING (Continued)
.Young children who get into
unlocked vehicles may be
unable to get out. A child can
be overcome by extreme heat
and can suffer permanent
injuries or even death from
heat stroke. Always lock the
vehicle whenever leaving it.
.Outsiders can easily enter
through an unlocked door
when you slow down or stop
the vehicle. Locking the doors

{WARNING
Exhaust gases can enter the
vehicle if it is driven with the
liftgate, 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 System in the Index.
.If the vehicle is equipped with
a power liftgate, disable the
power liftgate function.
For more information about
carbon monoxide, see Engine
Exhaust on page 9‑24.
To unlock the liftgate, use the
power door lock switch or press
the door unlock button on the

operation when the battery is
reconnected and charged.
If the battery is properly connected
and has adequate voltage, and the
liftgate still will not function, the
vehicle should be taken to a dealer

The power liftgate may be
temporarily disabled under extreme
temperatures or under low battery
conditions. If this occurs, the liftgate
can still be operated manually.
If the transmission is shifted out of
P (Park) while the power function
is in progress, the liftgate power
function will continue to completion.
If the transmission is shifted out of
P (Park) and the vehicle accelerates
before the power liftgate latches
closed, the liftgate may reverse to
the open position. Cargo could fall
out of the vehicle. Always make
sure the power liftgate is closed
and latched before you drive away.
If you power open the liftgate and
the liftgate support struts have lost
pressure, the lights will flash and a
chime will sound. The liftgate will
stay open temporarily, then slowly
close. See your dealer for service
before using the liftgate if this
occurs.Obstacle Detection Features
A warning chime will sound and the
liftgate will automatically reverse
direction to the full closed or open
position if the liftgate encounters
an obstacle during a power open
or close cycle. After removing the
obstruction, the power liftgate
operation can be used again.
If the liftgate comes across more
obstacles on the same power cycle,
the power function deactivates,
and you must manually open or
close the liftgate. A message
displays, LIFTGATE OPEN, to
indicate that the liftgate is open.
See
Driver Information Center (DIC)
(With DIC Buttons) on page 5‑25
or Driver Information Center (DIC) (Without DIC Buttons) on page 5‑30
for more information. After removing
the obstructions, manually open the
liftgate to the full open position or
close the liftgate to the fully closed
and latched position. The liftgate
resumes normal power operation.
The vehicle has pinch sensors
located on the side edges of the
liftgate. If an object is caught
between the liftgate and the body
and presses against this sensor,
the liftgate will reverse direction and
open fully. The liftgate will remain
open until it is activated again or
closed manually. Do not force the
liftgate open or closed during a
power cycle.

permanent injuries or even death
from heat stroke. Never leave a
child, a helpless adult, or a pet
alone in a vehicle, especially with
the windows closed in warm or
hot weather.

killed if caught in the path of a
closing window. Do not leave
keys in a vehicle with children.
