[LaGrant]

Buick Excelle steering wheel functions: The buttons on the right side are mainly used for controlling the infotainment system. When the Bluetooth phone system is not activated, pressing the call/voice recognition button briefly will enable the voice recognition system; when the radio is playing, pushing the volume adjustment button SRC up or down allows for tuning the radio station up or down; when playing external devices, selecting the previous or next track can be achieved by holding the button for fast forward or rewind. The buttons on the left side of the Buick Excelle steering wheel are used for controlling the cruise control system. Pressing the activation button will cause the control indicator light on the instrument cluster to illuminate in white. After accelerating to the desired speed, pressing the SET button can save and maintain the current speed, and the control indicator light on the instrument cluster will illuminate in green, at which point the accelerator pedal can be released.
