Rear Hatch/Rear Doors
CAUTION:
It can be dangerous to drive with the rear hatch
or rear doors open because carbon monoxide
(CO) gas can come into your vehicle. You can't
see or smell CO. It can cause unconsciousness
and even death.
If you must drive with the rear hatch or rear
doors open or if electrical wiring or other cable
connections must pass through the seal between
the body and the rear hatch or rear doors:

outside air into your vehicle. See "Comfort
Controls" in the Index.

If you have air outlets on or under the
instrument panel, open them all the way.
See "Engine Exhaust" in the Index.
