Infiniti QX56 (2008) [293/432] Vehicle to vehicle distance mode operation

Vehicle-to-vehicle distance mode

operation

Always pay attention to the operation of the ve-

hicle and be ready to manually control the proper

following distance. The Intelligent Cruise Control

(ICC) system may not be able to maintain the

selected distance between vehicles (following

distance) or selected vehicle speed under some

circumstances.

The vehicle-to-vehicle distance control mode

uses a sensor

located on the front of the

vehicle to detect vehicles ahead. The sensor

generally detects the signals returned from the

reflectors on a vehicle ahead. Therefore, if the

sensor cannot detect the reflector of the vehicle

ahead, the ICC system may not maintain the

selected distance.

The following are some conditions in which the

sensor cannot detect the signals:

● When the reflector is positioned high on the

vehicle (trailer, etc.).

● When the reflector on the vehicle ahead is

missing, damaged or covered.

● When the reflector is covered with dirt, snow

and road spray.

● When the snow or road spray from other

vehicles reduces the sensor’s visibility.

● When dense exhaust or other smoke (black

smoke) from vehicles reduces the sensor’s

visibility.

● When excessively heavy baggage is loaded

in the rear seat or the cargo area of your

vehicle.

● When your vehicle is towing a trailer, etc.

The ICC system is designed to automatically

check the sensor’s operation. When the sensor is

covered with dirt or obstructions, the system will

automatically be canceled while allowing con-

ventional cruise control to remain operational. If

the sensor is covered with ice, a transparent or

translucent vinyl bag, etc., the ICC system may

not detect them. In these instances, the vehicle-

to-vehicle distance control mode may not cancel

and may not be able to maintain the selected

following distance from the vehicle ahead. Be

sure to clean the sensor regularly.

The vehicle-to-vehicle distance control mode is

designed to maintain a selected distance and

reduce the speed to match the speed of a slower

vehicle ahead; the system decelerates the ve-

hicle as necessary. However, the ICC system can

only apply up to 25% of the vehicle’s total braking

power. This system should only be used when

traffic conditions allow vehicle speeds to remain

fairly constant or vehicle speeds change gradu-

ally. If a vehicle moves into the traveling lane

ahead or if a vehicle traveling ahead rapidly de-

celerates, the distance between vehicles may

become closer because the ICC system cannot

decelerate the vehicle quickly enough. If this oc-

curs, the ICC system will sound a warning chime

and blink the system display to notify the driver to

take necessary action.

The system will cancel and a warning chime will

sound if the speed falls below approximately 20

MPH (32km/h). The system will also disengage

below the 20 MPH (32km/h) cut-off speed or

over the maximum set speed.
