Warning light—driver braking required

Adaptive Cruise Control can exert brake force that is equivalent to approximately 40% of the vehicle's total braking capacity. In situations requiring more brake force than ACC can provide and if the driver does not apply the brakes, an audible signal from the Collision Warning system will sound and warning light will illuminate (see page 173) in the windshield to alert the driver to react.
NOTE
Strong sunlight, reflections, extreme light
contrasts, the use of sunglasses, or if the
driver is not looking straight ahead may
make the visual warning signal in the windshield
difficult to see.
WARNING
Adaptive Cruise Control only warns of vehicles
detected by the radar sensor, see
page 159. In some cases there may be no
warning or the warning may be delayed. The
driver should always apply the brakes when
necessary.
