To open the driver's sidedoor, first open the passenger's side door. Then, pull the handle on the left door edge out and pull the door open. The rear doors have a check assembly to keep them from fully opening during normal use. To close the doors, close the driver's side door first. After securely closing the door, close the passenger's side door. Make sure both doors are latched securely. To lock the rear doors from outside the vehicle, put your key in the lock and turn it to the right. If you have power door locks, you can lock the side doorsas well as the rear doors from inside the vehicle. For more information, see "Power Door Locks" in this section. To fully open either rear door, you must release the check strap. To release the check strap just: 1. Open the door partway until the white mark on the check strap is fully outside the door edge. If the end of the strap catches the pin on the door, the door is open too far. Theft Vehicle theft is big business, especially in some cities. Although your vehicle hasa number of theft-deterrent features, we know that nothing we put on it can make it impossible to steal. However, there are ways you can help. 2. Then, hold the strap at the white mark, pull the strap toward you and open the door all the way. Key in the Ignition If you leave your vehicle with the keys inside, it's an easy target for joy riders or professional thieves -- so don't do it. When you park your vehicle and open the driver's door, you'll hear a tone reminding you to remove your key from the ignition and take it with you. Always do this. Your steering wheel will be locked, and so will your ignition. If you have an automatic transmission, taking your key out also locks your transmission. And remember to lock the doors. To re-engage the door check strap, just close the door and the strap will catch the pin. 2-10
