Active Brake Assist 6 (ABA6) Collision Warning and Emergency Braking
Note: A driver can override ABA if, during an ABA braking event, the driver presses the accelerator pedal beyond the pressure point to engage kickdown, or through 99-100% throttle input if no kickdown switch is installed.
If there is a collision risk, ABA engages in the following cascade of warnings:
-
Issues Warnings: the radio and/or hands free system is muted, the vehicle issues a warning beeping, and an ABA collision warning window, shown in Fig. , appears on the driver display.
Fig. 1, First Visual ABA Warning - ICUC
-
Engages in Partial Braking: ABA brakes the vehicle with around 50 percent of the vehicle's maximum braking power.
The radio and/or hands free system stays muted, the warning beeping continues, and the ABA collision warning, shown in Fig. , continues to appear or, if previously dismissed, reappears on the driver display.
-
Engages in Emergency Braking: If a driver does not react to the collision warnings or partial brake application, ABA brakes the vehicle with 100 percent of the vehicle's maximum braking power.
The radio and/or hands free system stays muted, the warning beeping shifts to a continuous tone, and the emergency braking warning, shown in Fig. , appears on the driver display.

After emergency braking is completed, the driver should take the first opportunity to safely move the vehicle from traffic. Before continuing, the driver should confirm that the vehicle is in good operating condition and that the load is still properly secured.
Note: After an emergency braking maneuver has been performed, retake control of the vehicle and, if necessary, move the vehicle from the area of danger. After an ABA event has brought the vehicle to a standstill, only throttle pedal input is considered driver intent to move off. This means for manual transmission vehicles, releasing the clutch alone is not sufficient and the throttle pedal must also be used.
Take the first opportunity to safely move the vehicle from traffic to confirm the load is still properly secured and that the vehicle is still in good operating order. Failure to do so may result in personal injury and product or property damage.
Always apply the parking brake prior to exiting the vehicle.
