Nissan Qashqai e-POWER 2023 Owners Manual
8.23.1. IEB system operation
If a risk of a forward collision is detected, the IEB system will first provide a warning to the driver by flashing the warning (yellow) in the vehicle information display and providing an audible alert, and causing the brake system to pulse (quickly partially apply). In addition, the IEB system applies partial braking. If the driver applies the brakes quickly and forcefully, but the IEB system detects that there is still the possibility of a forward collision, the system will automatically increase the braking force.
If the driver does not take action, the IEB system issues the second visual warning (flashing red and white) and audible warning, then the system applies partial braking when the condition to do so is satisfied. If the risk of a collision becomes imminent, the IEB system applies harder braking automatically.
The IEB system will function when your vehicle is driven at speeds above approximately 5 km/h (3 MPH). For the pedestrian and cyclist detection function (where fitted), the IEB system operates at speeds between 10 and 80 km/h (6 and 50 MPH).
Junction assist (where fitted) operates at your vehicle speeds between 10 - 25 km/h (6 - 16 MPH).
When turning left or right, the turn signal must be activated to ensure that oncoming vehicles can be detected by Junction assist.
The vehicle’s brake lights come on when braking is performed by the IEB system.
When the IEB system detects an obstacle in the path of the vehicle and displays the IEB warning, a noise may be heard from the engine bay as the vehicle primes the brakes to improve response time.
Depending on vehicle speed and distance to the vehicle or pedestrian or cyclist ahead, as well as driving and roadway conditions, the system may help the driver avoid a forward collision or may help mitigate the consequences of a collision, should one be unavoidable. If the driver is handling the steering wheel, accelerating or braking, the IEB system will function later or will not function.
If the IEB system has stopped the vehicle, the vehicle will remain at a standstill for approximately 2 seconds before the brakes are released.
If the brake pedal is depressed while the brakes are being applied by the system, you may feel the pedal effort has changed and may hear a sound and feel vibration. This is normal and does not indicate a malfunction. In addition, the braking force can be increased by increasing the pedal effort.
The automatic braking will cease under the following conditions:
When the steering wheel is turned as far as necessary to avoid a collision.
When there is no longer a vehicle or pedestrian or cyclist detected ahead.
When the accelerator pedal is depressed.
