Lockout Protection To protect you from locking your key in the vehicle, this feature stops the power door locks from locking while the key is in the ignition and a door is open. If a power lock switch is pressed while a door is open and the key is in the ignition, all of the doors will lock and then the driver's door will unlock. A chime will sound continuously until all doors are closed. Trunk {CAUTION: It can be dangerous to drive with the trunk lid open because carbon monoxide (CO) gas can come into your vehicle. You can not see or smell CO. It can cause unconsciousness and even death. If you must drive with the trunk lid open or if electrical wiring or other cable connections must pass through the seal between the body and the trunk lid: • Make sure all other windows are shut. • Turn the fan on your heating or cooling 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. See Engine Exhaust on page 2-31. Leaving Your Vehicle If you are leaving the vehicle, take your keys, open your door and set the locks from inside. Then get out and close the door. 2-10
