Horn Sounds at Lock This feature sounds the horn once when the remote keyless entry transmitter is used to lock the vehicle. All doors must be closed for this feature to work. Programmable Modes Mode 1: ON Mode 2: OFF Before your vehicle was shipped from the factory, it was programmed to Mode 2. The mode to which the vehicle was programmed may have been changed since it left the factory. To program the vehicle to a different mode, use the following procedure: 1. Enter the personalization portion of the SETUP menu following the instructions listed previously. 2. Scroll to HORN SOUNDS AT LOCK to highlight it. 3. Press the TUNE/SEL knob to switch back and forth between on and off. When the mode is turned on, a check mark will appear next to the feature name. If you select this feature to be on, Lights Flash At Lock will also be on. You can choose Lights Flash At Lock by itself, but Horn Sounds At Lock will always have Lights Flash At Lock enabled when it is selected. The mode you selected is now set. You can either exit the programming mode by following the instructions later in this section or program the next feature available on your vehicle. Exterior Lights at Unlock This feature turns on the exterior lamps when the remote keyless entry transmitter is used to unlock the vehicle. The lamps will remain on for about 20 seconds unless a door is opened, the ignition is turned to ACCESSORY, ON or START or the remote keyless entry transmitter is used to lock the vehicle.
