Brake Assist: During an emergency, your foot comes off the throttle and on to the brake pedal faster than normal, which you then depress with more urgency than usual. This is registered by on-board sensors.

Next, a brake pedal load-sensing switch and speed sensor determine if you have braked hard enough. If not, the system instantly determines how much extra braking force is required. Then the brake actuator distributes the extra braking force to all four wheels to help you achieve smooth, safe, maximum braking.

It all happens in a split second and is so unobtrusive that you'll probably never know that Brake Assist has been at work.
