Door Locks - I There are several ways to lock and unlock your vehicle. From the outside, use your key or the remote lock control transmitter (if your vehicle has this option).

Outsiders caneasily enter through an unlocked door whenyou slow down or stop yourvehicle. so This may not be obvious: You increase the chance of being thrown out the vehicle in a of crash if the doors aren't locked. Wear safety belts properly, lock your doors, and you will be far better off whenever you drive your vehicle. -- -- To unlock either front door from the outside with the key, insert the key and turn it toward the front of the vehicle. You can lock either front door from the outside with your key by inserting and turning it toward the rear of the vehicle.
