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 35.
On vehicles with a power liftgate the
button is on the overhead console.
The vehicle must be in P (Park) to
use the power liftgate feature.
&
: Press the top of the button to
open or close the power liftgate.
OFF: Press the bottom of the
button for manual operation of the
power liftgate.
(Continued)
The taillamps will flash and a chime
will sound when the power liftgate is
moving.
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.
If you open the liftgate
without checking for overhead
obstructions such as a garage
door, you could damage the
liftgate or the liftgate glass.
Always check to make sure the
area above and behind the liftgate
is clear before opening it.
