The pre-collision system is enabled and the
system determines that the possibility of a
frontal collision with a vehicle, pedes-
trian/bicyclist, guardrail, etc. or a front side
collision with a vehicle is high. Each function
is operational at the following speeds:
● Pedestrian alert:
• Vehicle speed is between approximately
20 and 40 mph (30 and 65 km/h)
Pre-collision warning:
●
• Vehicle speed is between approximately
3 and 110 mph (5 and 180 km/h). (For
detecting a pedestrian or bicyclist, vehi-
cle speed is between approximately 3
and 50 mph [5 and 80 km/h] and for
detecting a vehicle approaching from the
front left or right side, vehicle speed is
between approximately 7 and 37 mph
[10 and 60 km/h].)
• The relative speed between your vehicle
and the detected pedestrian, bicyclist or
vehicle ahead is approximately 3 mph (5
km/h) or more. (For detecting a vehicle
approaching from the front left or right
side, the speed of the approaching vehi-
cle is between approximately 10 and 37
mph [15 and 60 km/h].)
● Pre-collision brake assist:
• Vehicle speed is between approximately
20 and 110 mph (30 and 180 km/h). (For
detecting a pedestrian or bicyclist, vehi-
cle speed is between approximately 20
and 50 mph [30 and 80 km/h] and for
detecting a vehicle approaching from the
front left or right side, vehicle speed is
between approximately 19 and 37 mph
[30 and 60 km/h].)
