When this function is turned on (the CRUISE indicator lights up on the display), the proper
volume level is automatically selected among the 3 possible levels according to the driving
speed, and the selected level is shown on the display.
To adjust the volume increase rate
If you find Audio Cruise increases (or decreases) the volume either too much or too little as
the driving speed changes, you can adjust the increase rate by changing the boost level.

If Audio Cruise does not function correctly
You may need to store the idling speed into memory to make Audio Cruise function correctly.
NOTICE that a number of factors, such as electric power steering, wipers, power windows, air
conditioner, etc. do generate noises and, as a result, may cause Audio Cruise not to function
correctly. If this is the main cause of malfunction, connect the memory backup lead (yellow
lead) directly to the car battery to prevent these noises from affecting Audio Cruise.
