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. 279)
● 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. 98)
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
A mute button will be displayed on the multi-information displa y when an
object is detected. To mute the buzzer, press .
Mute will be canceled automatically in the following situations :
● When the shift lever is changed.
● When the vehicle speed exceeds a certain speed.
● When the operating function is temporarily canceled.
● When the operating function is disabled manually.
● When the engine switch is turned off.

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
• 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 b etween
each vehicle
• When a vehicle is approaching at high speed
• Immediately after the RCTA function is set to on
• Immediately after the engine is started with the RCTA function is set to on
• When backing up on a slope with a
sharp change in grade
• When backing out of a shallow angle parking spot
• When the sensors cannot detect a vehicle due to obstructions

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
• When the parking space faces a
street and vehicles are being driven
on the street

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.

◆Hill-start assist control
Helps to reduce the backward movement of the vehicle when start-
ing on an uphill
◆EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to
turn the steering wheel.
The slip indicator light will flash
while the TRAC/VSC systems are
operating.
If the vehicle gets stuck in mud, dirt or snow, the TRAC system may
reduce power from the engine to the wheels. Pressing to turn
the system off may make it easier for you to rock the vehicle i n order
to free it.
To turn the TRAC system off,
quickly press and release .
A message will be shown on the
multi-information display.
Press again to turn the sys-
tem back on.

■Turning off both TRAC and VSC systems
To turn the TRAC and VSC systems off, press and hold for more than 3
seconds while the vehicle is stopped.
The VSC off indicator light will come on and the message will b e shown on
the multi-information display.
*
*
: On vehicles with pre-collision system, pre-collision brake assist and pre-
collision braking will also be disabled. The PCS warning light will come on
and the message will be shown on the multi-information display. (P. 241)
Press again to turn the systems back on.
■ When the message is displayed on the multi-information display show-
ing that TRAC has been disab led even if has not been pressed
TRAC is temporary deactivated. If the information continues to show, contact
your Toyota dealer.
■ Sounds and vibrations caused by the ABS, brake assist, VSC, TRAC and
hill-start assist control systems
●A sound may be heard from the engine compartment when the brake pedal
is depressed repeatedly, when the engine is started or just aft er the vehicle
begins to move. This sound does not indicate that a malfunction has
occurred in any of these systems.
● Any of the following conditions may occur when the above system s are
operating. None of these indicates that a malfunction has occur red.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard also after the vehicle comes to a s top.
• The brake pedal may pulsate slightly after the ABS is activate d.
• The brake pedal may move down sli ghtly after the ABS is activated.
■ Active Cornering Assist operation sounds and vibrations
When the Active Cornering Assist is operated, operation sounds and vibra-
tions may be generated from the brake system, but this is not a malfunction.
■ EPS operation sound
When the steering wheel is operated, a motor sound (whirring so und) may be
heard. This does not indicate a malfunction.
