Doors and Locks Door Locks There are several ways to lock and unlock your vehicle. From the outside, use the Remote Keyless Entry (RKE) transmitter or the key in the driver's door. From the inside, use the power door locks or manual door locks. To lock or unlock the door with the manual locks, push down or pull up on the manual lock knob. { CAUTION: Unlocked doors can be dangerous. • Passengers, especially children, can easily open the doors and fall out of a moving vehicle. When a door is locked, the handle will not open it. The chance of being thrown out of the vehicle in a crash is increased if the doors are not locked. So, all passengers should wear safety belts properly and the doors should be locked whenever the vehicle is driven. • Young children who get into unlocked vehicles may be unable to get out. A child can be overcome by extreme heat and can suffer permanent injuries or even death from heat stroke. Always lock the vehicle whenever leaving it. • Outsiders can easily enter through an unlocked door when you slow down or stop your vehicle. Locking your doors can help prevent this from happening. Power Door Locks On vehicles with power door locks, the switches are located on the front doors. " (Unlock): Press to unlock the doors. Q (Lock): Remove the key from the ignition and press to lock the doors. Delayed Locking The vehicle may have the delayed locking feature. When locking the doors with the power lock switch or the Remote Keyless Entry (RKE) transmitter and a door is open, the doors will lock five seconds after the last door is closed. You will hear three chimes to signal that the delayed locking feature is in use. Pressing the power lock switch twice or the lock button on the RKE transmitter twice will override the delayed locking feature and immediately lock all the doors. 2-9
