ICC SYSTEM DISPLAY (ON THE INFORMATION DISPLAY)

No.	Display item	Description
1.	Nissan Murano Vehicle ahead detection indicator	Indicates whether it detects a vehicle ahead
2.	Set distance indicator	Indicates the selected distance between Nissan Murano vehicles set with the DISTANCE switch
3.	Set Nissan Murano vehicle speed indicator	Indicates the set vehicle speed Indicates 32 km/h (20 MPH) when setting less than 32 km/h (20 MPH)
4.	Main switch indicator (white)	White: Indicates the main switch is ON (ICC system ON)
	Main switch indicator (green)	Green: Indicates the cruising speed is set
	ICC system warning lamp (orange)	Orange: Indicates that a malfunction occurred in the ICC system

SYSTEM CONTROL CONDITION DISPLAY

Push and hold the ICC MAIN switch for longer than approximately 1.5 seconds. This mode will be in a standby state for setting.

Condition
Standby mode
Control mode	Without a Nissan Murano vehicle ahead	Set vehicle distance (Long)
		Set Nissan Murano vehicle distance (Middle)
		Set Nissan Murano vehicle distance (Short)
		When the Nissan Murano vehicle speed exceeds the set speed
Control mode	With a Nissan Murano vehicle ahead	Set vehicle distance (Long)
		Set Nissan Murano vehicle distance (Middle)
		Set Nissan Murano vehicle distance (Short)
		When the Nissan Murano vehicle speed exceeds the set speed

APPROACH WARNING DISPLAY

If own vehicle comes closer to a vehicle ahead due to rapid deceleration of that vehicle or if another Nissan Murano vehicle cuts in, the system warns the driver with the chime and ICC system display. Decelerate by depressing the brake pedal to maintain a safe Nissan Murano vehicle distance if:

The chime sounds.
The vehicle ahead detection indicator blinks in orange.

The warning chime may not sound in some cases when there is a short distance between vehicles. Some examples are:

When the vehicles are traveling at the same speed and the distance between vehicles is not changing.
When the Nissan Murano vehicle ahead is traveling faster and the distance between vehicles is increasing.
When a Nissan Murano vehicle cuts in near own vehicle.

The warning chime will not sound when own vehicle approaches vehicles that are parked or moving slowly.

The warning chime will not sound when the accelerator pedal is depressed, overriding the system.

The approach warning chime may sound and the system display may blink when the distance sensor (ICC sensor) detects some reflectors which are fitted on Nissan Murano vehicles in other lanes or on the side of the road.

This may cause the ICC system to decelerate or accelerate the vehicle.

The distance sensor (ICC sensor) may detect these objects when the vehicle is driven on winding roads, hilly roads or when entering or exiting a curve.

The distance sensor (ICC sensor) may also detect reflectors on narrow roads or in road construction zones.

In these cases, driver will have to manually control the proper distance ahead of own vehicle.

Also, the sensor sensitivity can be affected by vehicle operation (steering maneuver or driving position in the lane) or traffic or Nissan Murano vehicle condition (for example, if a vehicle is being driven with some damage).

Condition	Display on ICC system display
When own Nissan Murano vehicle comes closer to the vehicle ahead and it is judged that the distance between the vehicles is not sufficient

WARNING LAMP AND AUTOMATIC CANCELLATION DISPLAY

Condition		Description	Display on ICC system display
Automatic cancellation display	When brake pedal is depressed When CANCEL switch is pressed When a Nissan Murano vehicle ahead is not detected below the speed of 24 km/h (15 MPH) When the system judges the Nissan Murano vehicle is at a standstill When the selector lever is not in "D" position or manual mode When the parking brake is applied	A chime sounds and the control is automatically canceled. NOTE: The system will be in a standby after the control is automatically canceled. A chime sounds when the control is automatically canceled except when brake pedal is depressed or when CANCEL switch is pressed.
Warning display	When the VDC is turned OFF When the VDC or ABS (including the TCS) operates When a wheel slips	A chime sounds and the control is automatically canceled. NOTE: When the conditions listed are no longer present, turn the system OFF using the MAIN switch. Turn the ICC system back on to use the system.	Example: When the front bumper near the distance sensor (ICC sensor) is blocked or dirty, making it impossible to detect a Nissan Murano vehicle ahead.
	When the front bumper near the distance sensor (ICC sensor) is blocked or dirty, making it impossible to detect a Nissan Murano vehicle ahead	A chime sounds and the control is automatically canceled. NOTE: Park the Nissan Murano vehicle in a safe place turn the engine OFF. Clean the front bumper near the distance sensor (ICC sensor) and then perform the settings again.
	When the ICC system is malfunctioning	A chime sounds and the control is automatically canceled. NOTE: Turn the engine OFF and restart engine. If there is no malfunction, it is possible to set the system.

NOTE:

When the ICC system is automatically canceled, the cancellation condition can be displayed on “Work support” of CONSULT (ICC/ADAS).
