WARNING
■Cautions regarding the use of the system
The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
The RCTA function is only an assist and is not a replacement for careful
driving. Driver must be careful when backing up, even when using RCTA
function. The driver’s own visual confirmation of behind you and your vehi-
cle is necessary and be sure there are no pedestrians, other vehicles, etc.,
before backing up. Failure to do so could cause death or serious injury.
According to conditions, the system may not function correctly. Therefore
the driver’s own visual confirmation of safety is necessary.

2984-5. Using the driving support systems
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 function is turned on.
● The shift lever 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 RCTA fu nction will not detect a vehicle
The RCTA function is not designed to detect the following types of vehicles
and/or objects:
● Small motorcycles, bicycles, pedestrians, etc.
*
●Vehicles approaching from directly behind
● Guardrails, walls, signs, parked vehicles and similar stationary objects\
*
●Vehicles moving away from your vehicle
● Vehicles approaching from the parking spaces next to your vehicle
*
●Vehicles backing up in the parking space next to your vehicle*
*
: Depending on the conditions, detection of a vehicle and/or object may
occur.

■Conditions under which the RCTA function may not function correctly
●The RCTA function may not detect vehicles correctly in the following condi-
tions:
• When the sensor is misaligned due to a strong impact to the sensor or its
surrounding area
• When ice or mud etc. is attached to the rear bumper
• During bad weather such as heavy rain, fog, snow, etc.
• When multiple vehicles approach continuously
• Shallow angle parking
• When a vehicle is approaching at high speed
• When parking on a steep incline, such as hills, a dip in the road, etc.
• Directly after the RCTA function is turned on
• Directly after the hybrid system is started with the RCTA function on.
• When items such as a bicycle carrier are installed on the rear of the vehi- cle
● Instances of the RCTA function unnecessarily detecting a vehicle and/or
object may increase in the following situations:
• When a vehicle passes by the side of your vehicle
• When the distance between your vehicle and metal objects, such as a
guardrail, wall, sign, or parked vehicle, which may reflect electrical waves
toward the rear of the vehicle, is short
The brightness for outside rear view mirror indicator can be changed
on (4.2-inch display) or (7-inch display) ( →P. 107, 123) of the
multi-information display.
• Vehicles that the sensors cannot detect because of obstacles
• When the parking space faces a street and vehicles are being driven
on the street

Rear Camera D etection Function∗
∗: If equipped
When the vehicle is backing up, the rear camera detection func-
tion can detect pedestrians in the detection area behind the
vehicle. If a pedestrian is detected, a buzzer will sound and an
icon on the audio system screen will be displayed to inform the
driver of the pedestrian.

The rear camera detection function is operational when the following condi-
tions are met:
●The power switch is in the ON mode.
● The shift lever is in R.
■ If the rear camera detection function is malfunctioning
If a malfunction of the rear camera detection function is detected, one of the
following messages will be displayed on the audio system screen. Have the
vehicle inspected by your Toyota dealer.
● “RCD malfunction.”
● “Visit your dealer.”
● “RCD unavailable.”

■Situations in which the system may not operate properly
●Some pedestrians, such as the following, may not be detected by the Rear
Camera Detection function, preventing the function from operating properly:
• Pedestrians who are squatting
• Pedestrians who are lying down
• Pedestrians who are running
• Pedestrians who suddenly enter the detection area
• Pedestrians riding a bicycle, skateboard, or other light vehicle
• Pedestrians wearing unusual clothing, such as a costume
• Pedestrians whose body is partially hidden by a cart or other object
• Pedestrians which are obscured by darkness, such as at night
● In some situations, such as the following, pedestrians may not be detected
by the Rear Camera Detection function, preventing the function from operat-
ing properly:
• When backing up in inclement weather (rain, snow, fog, etc.)
• When the rear camera is obscured (dirt, snow, ice, etc. are attached) or
scratched
• When a very bright light, such as the sun, or the headlights of another vehicle, shines directly into the rear camera
• When backing up in a place where the surrounding brightness changes
suddenly, such as at the entrance or exit of a garage or underground
parking lot
● In some situations, such as the following, the Rear Camera Detection func-
tion may operate even though there are no pedestrians in the detection
area.
• When a three dimensional object, such as a pole, traffic cone, fence, or
parked vehicle, is detected
• When a moving object, such as a car or motorcycle is detected
• When backing up toward moving objects such as flags or puddles, or air- borne matter, such as smoke, steam, rain, or snow
• When there is a pattern on the road, due to the road being made of cob- blestone or gravel or having tram rails, traces of repair, white lines,
pedestrian crossings or fallen leaves on the surface
• When backing up on a metal cover (grating), such as those used for drainage ditches
• When backing up toward the roadside or a bump in the road
• When an object is reflected in a puddle or on a wet road surface
• When there are shadows on the road
• When backing up over a bump in the road
• If the vehicle is significantly tilted, such as when carrying a heavy load
• When backing up toward an incline/decline
• If the suspension has been modified or tires of a size other than specified
are installed
• If the rear of the vehicle is raised or lowered due to the carried load
• If an electronic component, such as a backlit license plate (especially flu-
orescent type), is installed near the rear camera
• If a bumper protector, such as an additional trim strip, is installed to the rear bumper

• If the orientation of the rear camera has been changed due to a collisionor other impact, or removal and installation
• If a towing eyelet is installed to the rear of the vehicle
• When the rear camera is obscured (dirt, snow, ice, etc. are attached) or scratched
• When water is flowing over the rear camera lens
• If there is a flashing light in the detection area, such as the emergency flashers of another vehicle
■ Situations in which the Rear Camera Detection function may be difficult
to notice
●If buzzer may be difficult to hear if the surrounding area is noisy, the volume
of the audio system volume is high, the air conditioning system is being
used, etc.
● If the temperature in the cabin is extremely high or low, the audio system
screen may not operate correctly.
