- Always remember that the radar sensor
for the braking guard works only within
defined detection and range limits that
may prevent the proper detection of oth-
er vehicles.
- The radar sensor's function and range
can be reduced by rain, snow and heavy
spray. Moving vehicles up ahead may not
be promptly detected or may not be de-
tected at al l.
- Reflective surfaces including crash barr i-
ers or tunnel ent rances may impair the
function of the radar sensor.

- You can cancel the braking w ith increas-
ing force that is initiated by the system
by braking yo urself, by accelerating no-
ticeab ly or by swerving.
