Navigation/Radio System Your vehicle may have a navigation radio system. The navigation system has built-in features intended to minimize driver distraction. Technology alone, no matter how advanced, can never replace your own judgment. See the Navigation System manual for some tips to help you reduce distractions while driving. 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 does not operate and LOC, LOCK, or LOCKED could display. With THEFTLOCK® activated, the radio does not operate if stolen. Left-Side Steering Wheel Controls Right-Side Steering Wheel Controls Some audio controls can be adjusted at the steering wheel.
