sibly cause an accident.

excess of 10 km/h (6 mph).
● The sensors' detection areas and reac-
tion times are limited. When moving
forward or reversing, check the areas
surrounding the vehicle (especially the
sides of the vehicle) for safety, and
drive slowly, using the brake to control
the vehicle's speed.
Do not install accessories within the
●

The area directly under the bumpers is
●
not detected.
Thin posts or objects lower than the
sensor may not be detected when
approached, even if they have been
detected once.
