2-10 Keys, Doors and Windows
To open the liftgate, press the
touchpad on the underside of the
liftgate handle. The vehicle must
be in P (Park) to open the liftgate.
To close the liftgate, use the pull
cup or strap.
The liftgate has an electric latch.
If the battery is disconnected or
has low voltage, the liftgate will
not open. The liftgate will resume
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/retailer for service.
Power Liftgate Operation
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
liftgate. Engine exhaust contains
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.
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 23.
The vehicle may have a power
liftgate. The vehicle must be in
P (Park) to use this feature.
The taillamps will flash and a chime
will sound when the power liftgate
is used.
