Preview function (Intelligent Cruise Control system equipped models)  - Brake assist - Starting and driving - Infiniti QX Owners Manual - Infiniti QX

When the Preview Function identifies the need to apply emergency braking by sensing a vehicle ahead in the same lane and the distance and relative speed from it, it applies the brake pre-pressure before the driver depresses the brake pedal and helps improve brake response by reducing pedal free play.
► This system will not operate when the vehicle is moving at approximately 20 MPH (32 km/h) or less.
► The pre-pressure function ceases when the following conditions are met: 1) When the driver depresses the accelerator pedal or the brake pedal. 2) If the driver does not operate the accelerator or brake pedal within approximately 1 second. 3) When the 4WD shift switch is in the 4H or 4L position (for 4WD models).

► The sensor will not detect:

► The sensor will not detect: 1) Pedestrians or objects in the roadway 2) Oncoming vehicles in the same lane 3) Motorcycles traveling offset in the travel lane as illustrated

► This system is only an aid to assist WARNING

► This system is only an aid to assist braking operation and is not a collision warning or avoidance device. It is the driverТs responsibility to stay alert, drive safely and be in control of the vehicle at all times.
► As there is a performance limit to the Preview Function, never rely solely on this system. This system does not correct careless inattentive or absentminded driving, or overcome poor visibility in rain, fog, or other bad weather. Reduce vehicle speed by depressing the brake pedal, in order to maintain a safe distance between vehicles.
► The system may not detect the vehicle in front of you in certain road or weather conditions. The Preview Function may not operate properly under the following conditions. The vehicle is still driveable under normal conditions and the Brake Assist will operate. Ч When rain, snow or dirt adhere to the system sensor
Ч When strong light (for example, at sunrise or sunset) is directly shining on the front of the vehicle
Ч Winding or hilly roads may cause the sensor to temporarily not detect a vehicle in the same lane or may detect objects or vehicles in other lanes.
Ч Vehicle position in the lane may cause the sensor to temporarily not detect a vehicle in the same lane or may detect objects or vehicles in other lanes.

Warning light and display

When the Preview Function is not operating

When the Preview Function is not operating properly, the 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 and resume driving.

If the indicator stays on, it may indicate that the Preview Function is malfunctioning (the brake is operative). Although the Vehicle is still driveable under normal conditions, have the vehicle checked at an INFINITI retailer.

How to handle the sensor

The sensor for the Preview Function is common with Intelligent Cruise Control and is located below the front bumper. To keep the Preview Function operating properly, be sure to observe the following:
► Always keep the sensor clean. Wipe with a soft cloth carefully so as not to damage the sensor.
► Do not strike or damage the areas around the sensor. Do not touch or remove the screw located on the sensor. Doing so could cause failure or malfunction. If the sensor is damaged due to an accident, contact an INFINITI retailer.
► Do not attach a sticker (including transparent material) or install an accessory near the sensor. This could cause failure or malfunction.
