The Intelligent emergency brake (IEB) system may not react to slow moving vehicles.


The system will not react to stationary vehicles or vehicles that are not travelling in the same direction as your vehicle.


Warnings and automatic braking may not occur if the distance to the vehicle ahead is very small, or if the steering wheel and pedal movements are large (e.g., to avoid a collision).


IEB uses the same radar sensor as ACC and Forward alert. The same limitations of performance apply. See DESCRIPCIÓN GENERAL DEL CONTROL DE VELOCIDAD DE CRUCERO ADAPTATIVO.

When ACC is fitted, The IEB feature will be available at all speeds and will function even if ACC and Forward alert are switched off. The purpose of the IEB feature is to reduce the impact speed with a slower vehicle ahead when a collision becomes unavoidable.

If an imminent risk of collision occurs, an audible warning is given. If a collision becomes unavoidable, the IEB feature will apply the brakes at up to maximum pressure. After IEB has activated, IEB System Was Activated is displayed in the Message centre and the system is inhibited from further operation until reset by a Dealer/Authorised Repairer.


The distance required to slow or stop the vehicle is dependent on the condition of the vehicle's tyres and the current road surface.

If the radar sensor is blocked, by snow or heavy rain for example, or there is a fault with the system, IEB Not Available is displayed in the Message centre. The vehicle can still be driven and the braking system will still operate, but without IEB. If the radar sensor is not considered to be blocked, consult a Dealer/Authorised Repairer.
