Liftgate
WARNING
Exhaust gases can enter the
vehicle if it is driven with the
liftgate or 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 Systems 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 30.
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.
(Continued)
If you open the liftgate
The liftglass or liftgate cannot be
opened if the rear wiper is in motion.
Attempting to open the liftglass or
liftgate while the rear wiper is in
motion will cause the release of the
liftglass or liftgate to delay until the
wipers are parked off the liftglass.
