The areas that vehicles can be detected in are outlined below.
To give the driver a more consistent time to react, the buzzer can alert
for faster vehicles from farther away.
Example:
■ The RCTA function is operational when
●The RCTA system is set to on. ( P. 299)
● The shift position is in R.
● Vehicle speed is less than approximately 5 mph (8 km/h).
● Approaching vehicle speed is between approximately 5 mph (8 km/ h) and
18 mph (28 km/h).

Conditions under which the system will not detect a vehicle
The RCTA function is not designed to detect the following types of vehicles
and/or objects:
● Vehicles approaching from directly behind

● Guardrails, walls, signs, parked vehicles and similar stationar y objects
*
●Small motorcycles, bicycles, pedestrians, etc.*
●Vehicles moving away from your vehicle
● Vehicles approaching from the parking spaces next to your vehic le
*
●The distance between the sensor and approaching vehicle gets to o close
*: Depending on conditions, detection of a vehicle and/or object may occur.
■ Situations in which the syst em may not operate properly
The RCTA function may not detect vehicles correctly in the foll owing situa-
tions:
● When the sensor is misaligned due to a strong impact to the sensor or its
surrounding area
● When mud, snow, ice, a sticker, etc., is covering the sensor or surrounding
area on the position above 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 be tween
each vehicle
● When a vehicle is approaching at high speed
● When equipment that may obstruct a sensor is installed, such as a towing
eyelet, bumper protector (an additional trim strip, etc.), bicy cle carrier, or
snow plow
●
Vehicles that the sensors cannot detect
due to obstructions

When towing a trailer
● When there is a significant difference in height between your vehicle and the
vehicle that enters the detection area
● When a sensor or the area around a sensor is extremely hot or c old
● If the suspension has been modified or tires of a size other th an specified
are installed

Situations in which the system may operate even if there is no possibil-
ity of a collision
Instances of the RCTA function unnecessary detecting a vehicle and/or object
may increase in the following situations:
● When equipment that may obstruct a sensor is installed, such as a towing
eyelet, bumper protector (an additional trim strip, etc.), bicy cle carrier, or
snow plow
●
When a vehicle turns into the detection
area
● When the parking space faces a street
and vehicles are being driven on the
street
● When the distance between your vehicle
and metal objects, such as a guardrail,
wall, sigh, or parked vehicle, which may
reflect electrical waves toward the rear
of the vehicle, is short
● When a vehicle passes by the side of
your vehicle

● When the distance between your vehicle and a guardrail, wall, etc., that
enters the detection area is short
● Gratings and gutters
● When a sensor or the area around a sensor is extremely hot or c old
● If the suspension has been modified or tires of a size other th an specified
