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: 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 anything but MAX A/C. 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. Hatch Release You can use your key to unlock the hatch and all of the other doors from the outside. Insert the key into the hatch release button and turn it counterclockwise. All of the doors will unlock. You may also use the keyless entry system described earlier. The hatch can be opened or closed without a key if the door lock system is unlocked. 2-16
