Your vehicle cannot be locked using the remote key if the key is in the ignition and the ignition is ON. The vehicle also cannot be locked if the driver's door is open. To use the remote key to lock the doors, both doors must be closed. If only the passenger's door is open when the lock button is pressed, the driver's door will lock but the passenger's door will not. The horn will honk three times to indicate that the passenger's door has not locked. The passenger's door must be closed and the system must be reset in order to lock both doors. To reset the system, press the unlock button and then press the lock button on the remote key. Trunk {CAUTION: It can be dangerous to drive with the trunk lid 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 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 2-26. Programmable Automatic Door Locks Your vehicle is equipped with an automatic door locking feature which can be programmed through the trip computer buttons and instrument panel center display. It can be programmed to be on or off. See Vehicle Personalization on page 2-30 for more information.
