All doors can be locked or unlocked mechanically and independently with their respective locking knobs. The front doors can also be unlocked by actuation of the inside remote door handle.
The door locks can be locked or unlocked electrically via the exterior door key cylinders to provide the central locking/unlocking feature. The central locking/unlocking feature incorporates a customer programmable "Double activation unlock" feature which operates in the following manner: When enabled, the first turn of the key cylinder to the UNLOCK position (toward the front of the vehicle) will mechanically unlock the door whose key cylinder is being turned. A second turn of the key cylinder to the UNLOCK position (within five seconds of the first turn) will cause all vehicle doors and liftgate to unlock electrically. When this feature is disabled, all vehicle doors and liftgate will be unlocked electrically upon the first turn of a key cylinder to the UNLOCK position. The vehicle is locked electrically by turning the key cylinder to the LOCK position once, regardless of the state of the double activation unlock feature.
The transmitter has three buttons for operation: LOCK, UNLOCK and PANIC.
When the rolling door lock system is enabled, the RKE module will automatically lock all the vehicle doors and liftgate when all of the following conditions are met:
The RKE module will automatically re-lock all doors if the above conditions are met and if any of the doors become ajar and then closed again.
The enabling/disabling of the rolling door lock feature is customer programmable, as well as programmable with the scan tool.
The power lock motors are also equipped with a thermal protection system which prevents the motors from burning out. The motors may chatter if they are continuously activated.
