■ The Stop & Start system protection feature 
Vehicles without a smart entry & start system: When an excessively loud 
sound is being projected by the audio system, the audio system may be auto-
matically cut off in order to maintain power for the Stop & Start system func- 
tion. 
If this occurs, turning the engine switch to the “LOCK” position then to the
“ACC” or “ON” position re -enables the audio system. 
Vehicles with a smart entry & star t system: When an excessively loud sound 
is being projected by the audio system, the audio system may be automati-
cally cut off in order to maintain pow er for the Stop & Start system function.
