Some owners of the above vehicles may want to have the Automatic (Rolling) Door Lock feature disabled (turned off).
You can disable the Automatic (Rolling) Door Lock feature by either recalibrating the Body Control Module (BCM) or with the self-- programmable function. Use the following procedures:
Important: The feature may be turned off and covered under warranty on a one-time only basis. The system can be re-enabled (turned on) again at customer expense.
Important: Reprogramming this function for customer preference is not warranty. Please instruct the customers to refer to their Owner's Manual operator instructions or refer to below instructions.
The following is a list of the available programming options:
• | All doors lock at 24 km/h (15 mph), only driver's door unlocks when key is removed: Press the LOCK side of the power lock switch on the door panel ONCE, and then the UNLOCK side ONCE. |
• | All doors lock at 24 km/h (15 mph), all doors unlock when key is removed: Press the LOCK side of the power lock switch on the door panel ONCE, and then the UNLOCK side TWICE. (This is the factory setting) |
• | All doors lock at 24 km/h (15 mph), none of the doors unlock when key is removed: Press the LOCK side of the power lock switch on the door panel ONCE, and then the UNLOCK side THREE TIMES. |
• | No doors lock at 24 km/h (15 mph), none of the doors unlock when key is removed (Turns off automatic lock feature): Press the LOCK side of the power lock switch on the door panel TWICE. |
You can exit the program mode any time by turning the ignition to ON. The locks will automatically lock and unlock to indicate you are leaving the program mode. If the lock/unlock switches are not pressed while in the programming mode, the respective auto lock/unlock setting will not be modified.
