Liftgate

Warning
Exhaust gases can enter the
vehicle if it is driven with the
liftgate or trunk/hatch open,

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.
Adjust the climate control
system to a setting that
brings in only outside air

liftgate glass, make sure the area
above and behind the liftgate is
clear before opening it.
