To adjust the volume increase rate
If you find Audio Cruise increase (or decrease) the volume either too much or too little as the
driving speed changes. You can adjust the increase rate by changing the boost level.
To change it, follow the procedure below.
1. Press CRUISE to select either "CRUISE 1" or "CRUISE 2."
2. Press and hold CRUISE until the maximum boost level appears on the display.
Ex. When you have selected "CRUISE 2"
3. Turn the control dial, while the maximum boost level is shown on the display, to change
the boost level (among 01 to 15) as you want.
• To increase the volume increase rate, turn it clockwise.
• To decrease the volume increase rate, turn it counterclockwise.
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.
1. Start the engine and let it warm up.
2. Press CRUISE to select either "CRUISE 1" or "CRUISE 2."
3. Press and hold CRUISE and SEL for more than 2 seconds to store the idling speed into
memory.
Ex. When you have selected "CRUISE 2"
When the setting is complete, the unit automatically checks to see if Audio Cruise functions
correctly with this new idling setting. If it does not function correctly, Audio Cruise is canceled
automatically and the idling setting becomes invalid.
• If this happens, see the NOTICE above.
