Infotainment System
Traffic Voice Prompts
If the voice prompts are on,
whenever an Alert for Approaching
Traffic is displayed, the system
gives the related voice prompt.
The content of the voice prompt
depends on actual traffic event data.
The RPT (Repeat) control button
is for navigation traffic maneuvers
only. It is not used to repeat traffic
prompts. During a traffic voice
prompt, if RPT is pressed, the
current prompt playback cancels.
Anything that cancels the Alert for
Approaching Traffic, also cancels
the related voice prompt.
Traffic prompts are disabled during
OnStar
®
or Voice Recognition
activity.
