Using The Collision Warning System - Ford EXPLORER 2015 Owner's Manual

260
The brake support system assists the driver in reducing the collision
speed by charging the brakes. If the risk of collision further increases
after the warning light illuminates, the brake support prepares the brake
system for rapid braking. This may be apparent to the driver. The system
does not automatically activate the brakes but, if the brake pedal is
pressed, full force braking is applied even if the brake pedal is lightly
pressed.

Using the Collision Warning System

WARNING: The collision warning system's brake support can
only help reduce the speed at which a collision occurs if the
driver applies the vehicle's brakes. The brake pedal must be pressed
just like any typical braking situation.
The warning system sensitivity can be adjusted to one of three possible
settings by using the information display control. Refer to the
Information Displays chapter.
Note: If collision warnings are perceived as being too frequent or
disturbing then the warning sensitivity can be reduced, though the
manufacturer recommends using the highest sensitivity setting where
possible. Setting lower sensitivity would lead to fewer and later system
warnings. Refer to the Information Displays chapter for instructions on
reducing the sensitivity.
