Endgate/Liftgate CAUTION: It can be dangerous to drive with the rear window, endgate or liftgate 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 window, endgate or liftgate open or if electrical wiring or other cable connections must pass through the seal between the body and the rear window, endgate or liftgate: D Make sure all other windows are shut. D Turn the fan on your heating or cooling system to its highest speed with the setting on VENT or OUTSIDE AIR. That will force outside air into your vehicle. See "Comfort Controls" in the Index. D If you have air outlets on or under the instrument panel, open them all the way. See "Engine Exhaust" in the Index. Endgate Release To open a mechanical lock system from the outside, insert the key into the lock and turn it counterclockwise to unlock the glass.
