Navigation/Radio System Your vehicle may have a navigation radio system that includes Radio Data System (RDS) with Program Type (PTY) selections that will seek out the kind of music you want to listen to and XM™ Satellite Radio Service capabilities (if equipped). The radio can also communicate with the navigation system to broadcast announcements on traffic, weather, and emergency alert communications. For information on how to use this system, see the "Navigation System" manual. Audio Steering Wheel Controls Theft-Deterrent Feature THEFTLOCK® is designed to discourage theft of your vehicle's radio. The feature works automatically by learning a portion of the Vehicle Identification Number (VIN). If the radio is moved to a different vehicle, it will not operate. If the radio is removed from your vehicle, the original VIN in the radio can be used to trace the radio back to your vehicle. With THEFTLOCK® activated, the radio will not operate if stolen. Some audio controls can be adjusted at the steering wheel. They include the following: > (Mute): Press this button to silence the system. Press this button again, or any other radio button, to turn the sound on. SRCE (Source): Press this button to switch between FM1, FM2, AM, or XM1 or XM2 (if equipped), radio, or CD. 3-111
