Nissan X-Trail e-POWER 2023 Owners Manual
8.20.2.8. Approach warning
If your vehicle comes closer to the vehicle ahead due to rapid deceleration of that vehicle or if another 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 vehicle distance if:
The chime sounds.
The vehicle ahead detection indicator blinks.
The warning chime may not sound in some cases when there is a short distance between vehicles. Some examples are:
When the vehicles are travelling at the same speed and the distance between vehicles is not changing.
When the vehicle ahead is travelling faster and the distance between vehicles is increasing.
When a vehicle cuts in near your vehicle.
The warning chime will not sound when:
Your vehicle approaches other vehicles that are parked or moving slowly.
The accelerator pedal is depressed, overriding the system.
The approach warning chime may sound and the system display may blink when the radar sensor detects objects on the side of the vehicle or on the side of the road. This may cause the ICC system to decelerate or accelerate the vehicle. The radar sensor may detect these objects when the vehicle is driven on winding roads, narrow roads, hilly roads or when entering or exiting a curve. In these cases you will have to manually control the proper distance ahead of your vehicle.
Also, the sensor sensitivity can be affected by vehicle operation (steering manoeuvre or driving position in the lane) or traffic or vehicle condition (for example, if a vehicle is being driven with some damage).
