RCTA (Rear Cross Traffic Alert)
The RCTA function uses the BSM rear side radar sensors installe d
behind the rear bumper. This function is intended to assist the driver
in checking areas that are not easily visible when backing up.
Outside rear view mirror indicators
When a vehicle approaching from the right or left at the rear of the vehicle
is detected, both outside rear view mirror indicators will flas h.
RCTA buzzer
If a vehicle approaching from the right or left at the rear of the vehicle is
detected, a buzzer will sound. The buzzer also sounds for appro ximately 1
second immediately after the RCTA function is operated to turn the system
on.
“RCTA OFF” indicator
Illuminates when the Rear Cross Traffic Alert is disabled.

function will be enabled automatically.)
■ The outside rear view mirror indicators visibility
When under strong sunlight, the outside rear view mirror indica tor may be dif-
ficult to see.
■ Hearing the RCTA buzzer
The RCTA buzzer may be difficult to hear over loud noises, such as if the
audio system volume is high.
■ When “RCTA Unavailable.” is shown on the multi-information display
Water, snow mud, etc., may be built up in the vicinity of the s ensor area of
bumper ( P. 286).
Removing the water, snow, mud, etc., from the vicinity of the s ensor area
bumper should return it to normal.
Also, the sensor may not function normally when used in extremely hot or
cold weather
■ When “RCTA Malfunction Visit You r Dealer.” is shown on the multi-infor-
mation display
There may be a sensor malfunction or misaligned. Have the vehicle
inspected by your Toyota dealer.

The RCTA functions when your vehicle is in reverse. It can dete ct
other vehicles approaching from the right or left rear of the v ehicle. It
uses radar sensors to alert the driver of the other vehicle’s existence
through flashing the outside rear view mirror indicators and so unding
a buzzer.

WARNING
■Cautions regarding the use of the function
The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
The RCTA function is only a supplementary function which alerts the driver
that a vehicle is approaching from the right or left at the rea r of the vehicle.
As the RCTA function may not function correctly under certain c onditions,
the driver’s own visual confirmation of safety is necessary. Ov er reliance on
this function may lead to an accident resulting death or seriou s injury.

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.

■The RCTA function is operational when
The RCTA function operates when all of the following conditions are met:
● The RCTA system is set to on. ( P. 293)
● 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).
■ Adjusting the buzzer volume
The buzzer volume can be adjusted on the multi-information disp lay.
Use the meter control switches to change settings. ( P. 100)
Press “ ” or “ ” to select .
Press “ ” or “ ” to select “Vehicle Settings”, and then press .
Press “ ” or “ ” to select , select the volume and then press
.
Each time the switch is pressed, the volume level will change between 1, 2
and
3.
■ Muting a buzzer

Conditions under which the RCTA function 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
● Vehicles backing up in a parking space next to your vehicle
● 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
*
*
: Depending on the conditions, detection of a vehicle and/or obj ect may
occur.
●
Vehicles that the sensors cannot detect
due to obstructions

Conditions under which the RCTA function may not function corre ctly
● The RCTA function may not detect vehicles correctly in the following situa-
tions:
• When the sensor is misaligned due to a strong impact to the se nsor or its
surrounding area
• When mud, snow, ice, a sticker, etc., is covering the sensor o r surround-
ing area on the rear bumper

Instances of the RCTA function unnecessarily detecting a vehicl e 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

Driving assist systems
◆ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenl y,
or if the brakes are applied while driving on a slippery road surface
◆Brake assist
Generates an increased level of braking force after the brake p edal
is depressed when the system de tects a panic stop situation
◆VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or
turning on slippery road surfaces
◆Enhanced VSC (Enhanced Vehicle Stability Control)
Provides cooperative control of the ABS, TRAC, VSC and EPS.
Helps to maintain directional stability when swerving on slippe ry
road surfaces by controlling steering performance
◆TRAC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from
spinning when starting the vehicl e or accelerating on slippery roads
◆Active Cornering Assist (ACA)
Helps to prevent the vehicle from drifting to the outer side by per-
forming inner wheel brake control when attempting to accelerate
while turning.
To keep driving safety and perf ormance, the following systems
operate automatically in respon se to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too heav ily when operating the vehi-
cle.
