Programmable Modes Your vehicle can be programmed to one of the following modes. Mode 1: No Verification Mode 2: Horn Chirp only Mode 3: Headlamp Flash only Mode 4: Horn Chirp and Headlamp Flash Before your vehicle was shipped from the factory, it was programmed to Mode 3. The mode to which your vehicle was programmed may have been changed since it left the factory. To determine the security feedback lock mode to which your vehicle is programmed or to program your vehicle to a different mode, do the following: 1. Close all doors and turn the ignition key to RUN. 2. Press and hold the power door lock switch in the lock position. 3. While holding the door lock switch in the lock position, press and release the remote keyless entry transmitter LOCK button. This will start the customization mode. While in the customization mode, the feature will sound the number of chimes corresponding to the current lock mode. (If you do not wish to change the current mode, you can either exit the programming mode by following the instructions listed here or program the next feature available on your vehicle.) 4. Each additional press of the remote keyless entry transmitter LOCK button will cause your vehicle to advance the lock mode by one, starting from the current lock mode. 5. If cycled beyond lock Mode 4, the vehicle will enter Mode 1. When the door lock switch is released, the vehicle will remain in the most recent lock mode. 2-12
