Canceling the Rear Door Security Locks 1. Unlock and open the rear door from the outside. 2. Push the lever down to disengage the safety lock. 3. Close the door. 4. Repeat Steps 1 through 3 for the other rear door lock. The rear door locks will now work normally. Liftgate {CAUTION: It can be dangerous to drive with the 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 liftgate open or if electrical wiring or other cable connections must pass through the seal between the body and the liftgate: • 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" in the Index. Lockout Protection The lockout protection feature may prevent you from locking your key in your vehicle. Pressing the power door lock switch will lock all doors, then unlock the driver's door, if the key is in the ignition when a door is opened. If you leave the key in your vehicle but not in the ignition or if you use the manual door lock, you could still lock the key in the vehicle. Always remember to take the key with you. Leaving Your Vehicle If you are leaving the vehicle, take your key, open your door and set the locks from the inside. Then get out and close the door. 2-11
