It can be dangerous to drive with the liftgate or liftglass open because carbon monoxide (CO) gas can come into your vehicle. You cannot see or smell CO.

It can cause unconsciousness and even death. If you must drive with the liftgate open or if electrical wiring or other cable connections must pass through the seal between the body and the liftgate or liftglass:
• Make sure all other windows are shut.
• Turn the fan on your climate control system to its highest speed and select the control setting that will force outside air into your vehicle. See “Climate Control System” in the Index.
• If you have air outlets on or under the instrument panel, open them all the way.
