Make sure the relevant safety warnings and notes have been read and understood before driving the vehicle. See AUTONOMOUS EMERGENCY BRAKING (AEB) SAFETY.


Not all vehicles are fitted with Autonomous Emergency Braking (AEB). Consult a retailer/authorised repairer for confirmation.


The driver is recommended to switch off the AEB system when driving off-road, when using a car wash, or when the vehicle is being towed.

AEB uses forward-facing cameras, located above the rear-view mirror, and forward-facing radars, located on the front bumper, to help identify an imminent risk of collision with:

  • Another vehicle travelling in front.

  • An oncoming vehicle from adjacent lane while host vehicle turning left or right.

  • A crossing pedestrian.

  • A pedestrian moving in the same direction as the vehicle.

  • An oncoming pedestrian from opposite direction while host vehicle turning left or right.

  • A crossing cyclist.

  • A cyclist travelling in the same direction as the vehicle.

  • An oncoming cyclist from opposite direction while host vehicle turning left or right.

In most instances, AEB helps reduce the severity of an impact. In some cases, AEB helps to stop the vehicle before an impact takes place.

AEB automatically switches on, every time the vehicle’s electrical system is switched on.

If required, the AEB feature can be switched off via the touchscreen. To switch AEB off, complete the following steps:

  1. Touch the settings icon from any screen. See SYSTEM SETTINGS.

  2. Select Vehicle.

  3. Select Driver Assistance.

  4. Select Collision avoidance.

  5. Emergency braking: Touch to switch the toggle on or off.

AEB operates at speeds above 5 km/h (3 mph).

The vehicle detection AEB system can detect:

  • Vehicles travelling in the same road lane of speeds up to 130 km/h (80 mph).

  • Vehicles travelling in the adjacent road lane of speeds up to 64 km/h (39 mph). The system only detects other vehicles when host vehicle is turning left or right, with a speed of up to 20 km/h (12 mph).

The pedestrian and cyclist detection AEB systems are able to operate at speeds of up to 60 km/h (37 mph).

If an imminent risk of a collision is detected, the system automatically applies the brakes. The instrument panel also displays a warning message while AEB is operating.


If AEB brings the vehicle to a stop, the brakes continue to hold the vehicle stationary for a few seconds. After this period, the driver must resume full control of the vehicle. Failure to take back full control of the vehicle could result in an accident, leading to serious injury or death.


The brake lights are automatically operated in heavy braking situations.


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

The driver can override AEB operation by turning the steering wheel, or pressing the accelerator pedal. When overridden, AEB cancels its request for braking to make sure that the driver remains in full control of the vehicle.

After AEB has been activated, a warning sounds and the instrument panel displays a warning message.
