Lock Feedback The lock feedback feature can be programmed to one of the following modes: OFF: When LOCK is pressed on the remote keyless entry transmitter, the headlamps and parking lamps will not flash and the horn will not sound. LIGHTS: When LOCK is pressed on the remote keyless entry transmitter, the headlamps and parking lamps will flash briefly. LIGHTS and HORN: When LOCK is pressed a second time on the remote keyless entry transmitter within five seconds, the headlamps and parking lamps will flash briefly and the horn will sound. Before your vehicle was shipped from the factory, it was programmed in LIGHTS and HORN. The mode to which the vehicle has been programmed may have been changed since it left the factory. To determine the mode to which your vehicle is programmed or to program your vehicle to a different mode, do the following: 1. Follow the instructions for "Entering Programming Mode" listed previously. 2. Press the MODE button until LOCK FEEDBACK appears on the DIC. 3. Press the SET button until the arrow is before OFF, LIGHTS or LIGHTS and HORN. The mode you selected is now set. You can either exit programming mode by following the instructions later in this section or program the next feature available on your vehicle. 2-119
