Conditions under which the RCTA func-
tion may not function correctly
●
The RCTA function may not detect vehi-
cles correctly in the following situations:

strong impact to the sensor or its sur-
rounding area
• When mud, snow, ice, a sticker, etc. is
covering a sensor or its surrounding area
on the rear bumper
• When driving on a road surface that is
wet with standing water during bad
weather, such as heavy rain, snow, or fog
• When multiple vehicles are approaching
with only a small gap between each vehi-
cle
• If a vehicle is approaching the rear of
your vehicle rapidly
• When a towing eyelet is installed to the
rear of the vehicle.

change in grade
• When backing out of a shallow angle
parking spot
• Immediately after the RCTA function is
turned on
• Immediately after the hybrid system is
started with the RCTA function on

cle due to obstructions

sarily detecting a vehicle and/or object
