Situation |
Actions |
|
When the area around a sensor is covered with dirt, moisture (fogged up, covered with condensation, ice, etc.), or other foreign matter |
To clean the part of the windshield in front of the front camera, use the windshield wipers or the windshield defogger of the air conditioning sys- tem (P.398). |
|
Situation |
Actions |
|
When the temperature around the front camera is outside of the opera- tional range, such as when the vehi- cle is in the sun or in an extremely cold environment |
If the front camera is hot, such as after the vehicle had been parked in the sun, use the air conditioning sys- tem to decrease the temperature around the front camera. If a sunshade was used when the vehicle was parked, depending on its type, the sunlight reflected from the surface of the sunshade may cause the temperature of the front camera to become excessively high. |
|
If the front camera is cold, such as after the vehicle is parked in an extremely cold environment, use the air conditioning system to increase the temperature around the front camera. |
|
|
The area in front of the front camera is obstructed, such as when the hood is open or a sticker is attached to the part of the windshield in front of the front camera. |
Close the hood, remove the sticker, etc. to clear the obstruction. |
If the message does not disappear, contact your Toyota dealer.

System functions |
The system can detect the fol- lowing:
When the system determines that the possibility of a frontal collision is high, the system applies greater braking force in relation to how strongly the brake pedal is depressed.
If the system determines that the possibility of a frontal colli- sion is extremely high, the brakes are automatically applied to help avoid the collision or reduce the impact of the colli- sion.
|
Changing settings of the pre-collision system |

screen (P.177) of the multi- information display.
The system is automatically enabled each time the power switch is turned to ON.
|
|
The pre-collision warning timing
can be changed on the 
screen (P.177) of the multi- information display.
The warning timing setting is retained when the power switch is turned to OFF. However, if the pre- collision system is disabled and re- enabled, the operation timing will return to the default setting (mid- dle).
|

In the following situations, a warning message urging the driver to hold the steering wheel and the symbol shown in the illustration are dis- played on the multi-information dis- play to warn the driver. The warning stops when the system determines that the driver holds the steering wheel. Always keep your hands on the steering wheel when using this system, regardless of warnings.
If the driver continues to keep their hands off of the steering wheel, the buzzer sounds, the driver is warned and the function is temporarily can- celed. This warning also operates in the same way when the driver con- tinuously operates the steering wheel only a small amount.
The buzzer also sounds even if the alert type is set to “Steering wheel vibration”.
Depending on the vehicle condition and road conditions, the warning may not operate. Also, if the system determines that the vehicle is driv- ing around a curve, warnings will occur earlier than during straight- lane driving.
If the driver continues to keep their hands off of the steering wheel and the steering wheel assist is operat- ing, the buzzer sounds and the driver is warned. Each time the buzzer sounds, the continuing time of the buzzer becomes longer.
The buzzer also sounds even if the alert type is set to “Steering wheel vibration”.
When the system determines that the vehicle is swaying while the vehicle sway warning function is operating, a buzzer sounds and a warning message urging the driver to rest and the symbol shown in the illustration are simultaneously dis- played on the multi-information dis- play.
Depending on the vehicle and road conditions, the warning may not operate.
If the following warning message is displayed on the multi-information
display and the LTA indicator illumi- nates in orange, follow the appropri- ate troubleshooting procedure. Also, if a different warning message is displayed, follow the instructions displayed on the screen.
The system may not be operating properly. Have the vehicle inspected by your Toyota dealer.

Before using dynamic radar cruise control with full-speed range
Driving safely is the sole responsibility of the driver. Do not rely solely on the system, and drive safely by always pay- ing careful attention to your sur- roundings.

WARNING
When driving on downhill slopes, the vehicle-to-vehicle distance may become shorter.
The vehicle travels at the speed set by the driver.
When a vehicle is detected running ahead of you, the system automatically decelerates your vehicle. When a greater reduction in vehicle speed is nec- essary, the system applies the brakes (the stop lights will come on at this time). The system will respond to changes in the speed of the vehicle ahead in order to maintain the vehicle-to-vehicle distance set by the driver. Approach warning warns you when the system cannot decelerate suffi- ciently to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your vehicle will also stop (vehicle is stopped by system control). After the vehicle ahead starts off, pressing the “+RES” switch or depressing the accelerator pedal (start-off operation) will resume follow-up cruising. If the start-off operation is not performed, system
control continues to keep your vehicle stopped.
When the turn signal lever is operated and your vehicle moves to an over- taking lane while driving at 50 mph (80 km/h) or more, the vehicle will accel- erate to help to overtake a passing vehicle.
The system’s identification of what is an overtaking lane may be deter- mined solely based on the location of the steering wheel in the vehicle (left side driver position versus right side driver position.) If the vehicle is driven to a region where the overtaking lane is on a different side from where the vehicle is normally driven, the vehicle may accelerate when the turn signal lever is operated in the opposite direction to the overtaking lane (e.g., if the driver normally operates the vehicle in a region where the overtaking lane is to the right but then drives to a region where the overtaking lane is to the left, the vehicle may accelerate when the right turn signal is activated).
When there are no longer any preceding vehicles driving slower than the set speed
The system accelerates until the set speed is reached. The system then returns to constant speed cruising.
(P.343)
Dynamic radar cruise control indi- cator will come on and a message will be displayed on the multi-infor- mation display. Press the switch again to deactivate the cruise con- trol.
If the cruise control main switch is pressed and held for 1.5 seconds or more, the system turns on in constant speed control mode.
Cruise control “SET” indicator will come on.
The vehicle speed at the moment the switch is released becomes the

Resuming follow-up cruising when the vehicle has been stopped by sys- tem control (vehicle-to- vehicle distance control mode) |
After the vehicle ahead of you starts off, press the “+RES” switch.
Your vehicle will also resume follow-up cruising if the acceler- ator pedal is depressed after the vehicle ahead of you starts off.
The speed control is also canceled when the brake pedal is depressed. (When the vehicle has been stopped by system control, depressing the brake pedal does not cancel the setting.)
When your vehicle is too close to a vehicle ahead, and suffi- cient automatic deceleration via
the cruise control is not possi- ble, the display will flash and the buzzer will sound to alert the driver. An example of this would be if another driver cuts in front of you while you are following a vehicle. Depress the brake pedal to ensure an appropriate vehicle-to-vehicle distance.
In the following instances, warn- ings may not occur even when the vehicle-to-vehicle distance is small.
|
Selecting constant speed control mode |
When constant speed control
mode is selected, your vehicle will maintain a set speed without controlling the vehicle-to-vehi- cle distance. Select this mode only when vehicle-to-vehicle dis- tance control mode does not function correctly due to a dirty radar, etc.
Immediately after the switch is pressed, the dynamic radar cruise control indicator will come on. After- wards, it switches to the cruise con- trol indicator.
Switching to constant speed control mode is only possible when operat- ing the switch with the cruise con- trol off.
Cruise control “SET” indicator will come on.
The vehicle speed at the moment the switch is released becomes the set speed.

A brake operation sound may be heard and the brake pedal response may change, but these are not mal- functions.
Warning messages and buzzers are used to indicate a system malfunc- tion or to inform the driver of the need for caution while driving. If a warning message is shown on the multi-information display, read the message and follow the instructions. (P.313, 523)
In the case of the following and depending on the conditions, oper- ate the brake pedal when decelera- tion of the system is insufficient or operate the accelerator pedal when acceleration is required.
As the sensor may not be able to correctly detect these types of vehi- cles, the approach warning (P.343) may not be activated.
In the case of the following condi- tions, operate the brake pedal (or accelerator pedal, depending on the situation) as necessary.
As the sensor may not be able to correctly detect vehicles ahead, the system may not operate properly.

If the vehicle is stopped due to oper- ation of the Parking Support Brake, the Parking Support Brake will be disabled and the PKSB OFF indica- tor will illuminate. If the Parking Sup- port Brake operates unnecessarily, brake control can be canceled by depressing the brake pedal or wait- ing for approximately 2 seconds for it to automatically be canceled.
Then, the vehicle can be operated by depressing the accelerator pedal.
To re-enable the Parking Support Brake when it is disabled due to operation of the Parking Support Brake, either enable the system again (P.364), or turn the power switch off and then back to ON. Additionally, if the object becomes no longer in the traveling direction of the vehicle or if the traveling direc- tion of the vehicle changes (such as changing from moving forward to backing up, or from backing up to moving forward), the system will be re-enabled automatically.

Summary of the driving assist systems |
Helps to prevent wheel lock when the brakes are applied suddenly, or if the brakes are applied while driving on a slip- pery road surface
Generates an increased level of braking force after the brake pedal is depressed when the system detects a panic stop sit- uation
Helps the driver to control skid- ding when swerving suddenly or turning on slippery road sur- faces.
Provides cooperative control of the ABS, TRAC, VSC and EPS.
Helps to maintain directional stability when swerving on slip- pery road surfaces by con- trolling steering performance.
Helps the driver to control trailer sway by selectively applying brake pressure for individual wheels and reducing driving torque when trailer sway is detected.
Helps to maintain drive power and prevent the drive wheels from spinning when starting the vehicle or accelerating on slip- pery roads
Helps to prevent the vehicle from drifting to the outer side by
movement of the vehicle when starting on an uphill
Employs an electric motor to reduce the amount of effort needed to turn the steering wheel
Automatically switches from front wheel drive to all-wheel drive (AWD) according to the driving conditions, helping to ensure reliable handling and stability. Examples of condi- tions where the system will switch to AWD are when corner- ing, going uphill, starting off or accelerating, and when the road surface is slippery due to snow, rain, etc.
When the SRS airbag sensor detects a collision and the sys- tem operates, the brakes and brake lights are automatically controlled to reduce the vehicle speed and help reduce the pos- sibility of further damage due to a secondary collision.
