Lincoln 2011 MKX - Manual (Page 237)

Operation
The radar sensor detects vehicles
ahead that are moving in the same
direction as your vehicle.
If the radar detects that your
vehicle is rapidly closing on another
vehicle a red warning light will
illuminate and an audible warning
chime will sound.
After that, if the risk of collision
further increases after the warning
light, the brake support prepares
the brake system for rapid braking.
This may be apparent to the driver.
However, the system will not
automatically activate the brakes.
The vehicle will not stop unless the driver presses the brake pedal. If the
brake pedal is pressed then braking is implemented with full brake
function, even if the force on the brake pedal is light.
The collision warning system is active at speeds above approximately
5 mph (8 km/h).
Collision warning system limitations
Due to the nature of radar technology, there may be certain instances
where vehicles will not provide a collision warning. These include:
• Stationary or slow moving vehicles below 6 mph (10 km/h).
• Pedestrians or objects in the roadway.
• Oncoming vehicles in the same lane.
• Severe weather conditions (see also blocked sensor section).
• Debris build-up on the grille near the headlamps (see block sensor
section).
• Small distance to vehicle ahead.
• Steering wheel and pedal movements are large (very active driving
style).
• High interior temperatures, which may deactivate the illumination or
the warning lamps until the interior temperature reduces (audible
warning will alert the driver).
In addition, sun load and sunglasses may reduce the visibility of the
warning lamps. Therefore, it is recommended to keep the audible
warning on.
