Nissan Maxima Owners Manual: System temporarily unavailable
The following are conditions in which the ICC system may be temporarily unavailable. In these instances, the ICC system may not cancel and may not be able to maintain the selected following distance from the vehicle ahead.
Condition A
Under the following conditions, the ICC system is automatically canceled. A chime will sound and the system will not be able to be set:
- When the VDC system is turned off
- When the VDC or ABS (including the TCS) operates
- When a vehicle ahead is not detected and your vehicle is traveling below the speed of 15 mph (24 km/h)
- When the system judges the vehicle is at a standstill
- When the shift lever is not in the D (Drive) or Manual mode
- When the parking brake is applied
- When a wheel slips
Action to take
When the conditions listed above are no longer
present, turn the system off using the ICC
CRUISE 
switch. Turn the ICC system
back
on to use the system.
Condition B
When the radar sensor area of the front bumper is covered with dirt or is obstructed, the ICC system will automatically be cancelled. If the sensor area is covered with ice, a transparent or translucent vinyl bag, etc., the ICC system may not detect vehicles ahead. In these instances, the ICC system may not cancel and may not be able to maintain the selected following distance from the vehicle ahead. Be sure to check and clean the sensor area.
The system warning light (orange) will illuminate and the "front radar obstruction" warning message will appear in the vehicle information display.
Action to take
If the warning light (orange) comes on, park the vehicle in a safe location and turn the engine off.
Check to see if the radar sensor window is blocked. If the radar sensor window is blocked, remove the blocking material. Restart the engine.
If the warning light continues to illuminate, have the ICC system checked. It is recommended that you visit a NISSAN dealer for this service.
Condition C
When the ICC system is not operating properly, a chime sounds and the system warning light (orange) will come on.
Action to take
If the warning light comes on, park the vehicle in a safe place. Turn the engine off, restart the engine, resume driving and set the ICC system again.
If it is not possible to set the system or the indicator stays on, it may indicate that the system is malfunctioning. Although the vehicle is still drivable under normal conditions, have the vehicle checked. It is recommended that you visit a NISSAN dealer for this service.
