Audio Steering Wheel Controls If your vehicle has this feature, some audio controls can be adjusted at the steering wheel. They include the following: g (Mute/Voice Activation): Press this button to silence the system. Press this button again to turn the sound on. If your vehicle has OnStar®, press and hold this button for two seconds to activate voice on the OnStar® system. See the OnStar® System on page 2-44 in this manual for more information. Radio Reception Frequency interference and static can occur during normal radio reception if items such as cell phone chargers, vehicle convenience accessories, and external electronic devices are plugged into the accessory power outlet. If there is interference or static, unplug the item from the accessory power outlet. x w (Next/Previous): Press the arrows to go to the next or to the previous stored radio station and stay there. Press and hold the arrows longer than three-quarters of a second to advance ahead or reverse back to a station with a strong signal in the selected band. When a CD is playing, press the arrows to go to the next or to the previous track. Press and hold the arrows longer than three-quarters of a second to continue advancing ahead or reversing back to other tracks within the disc. + e − e (Volume): Press the plus or minus button to increase or to decrease the radio volume. AM The range for most AM stations is greater than for FM, especially at night. The longer range can cause station frequencies to interfere with each other. For better radio reception, most AM radio stations boost the power levels during the day, and then reduce these levels during the night. Static can also occur when things like storms and power lines interfere with radio reception. When this happens, try reducing the treble on your radio. 3-79
