Before starting
To get the best recognition performance from Voice Recognition, observe the following:
● The interior of the vehicle should be as quiet as possible. Close the windows to eliminate the surrounding noises (traffic noise and vibration sounds, etc.), which may prevent the system from correctly recognizing the voice commands.
● Wait until the tone sounds before speaking a command.
● Speak in a natural conversational voice without pausing between words.
● If the air conditioner is set to “Auto”, the fan speed is automatically lowered so that your commands can be recognized more easily.
