PKSB (Parking Support Brake)^{* *}If equipped The Parking Support Brake system consists of the following functions that operate when driving at a low speed or backing up, such as when parking. When the system determines that the possibility of a collision with a detected object is high, a warning operates to urge the driver to take evasive action. If the system determines that the possibility of a collision with a detected object is extremely high, the brakes are automatically applied to help avoid the collision or help reduce the impact of the collision. PKSB (Parking Support Brake) system Parking Support Brake function (static objects) Parking Support Brake function (static objects)* Parking Support Brake function (rear-crossing vehicles) (if equipped) Parking Support Brake function (rear-crossing vehicles)* Warning: Limitations of the Parking Support Brake system Do not overly rely on the system, as doing so may lead to an accident. Always drive while checking the safety of the surroundings of the vehicle. Depending on the vehicle and road conditions, weather, etc., the system may not operate. The detection capabilities of sensors and radars are limited. Always drive while checking the safety of the surroundings of the vehicle. The driver is solely responsible for safe driving. Always drive carefully, taking care to observe your surroundings. The Parking Support Brake system is designed to provide support to lessen the severity of collisions. However, it may not operate in some situations. The Parking Support Brake system is not designed to stop the vehicle completely. Additionally, even if the system has stopped the vehicle, it is necessary to depress the brake pedal immediately as brake control will be canceled after approximately 2 seconds. Notice: If “ Parking Support Brake Unavailable” is displayed on the multi-information display and the PKSB OFF indicator is flashing If this message is displayed immediately after the engine switch is changed to ON, operate the vehicle carefully, paying attention to your surroundings. It may be necessary to drive the vehicle for a certain amount of time before the system returns to normal. (If the system is not return to normal after driving for a while, clean the sensors and their surrounding area on the bumpers.) Switches PKSB (Parking Support Brake) Enabling/Disabling the Parking Support Brake The Parking Support Brake can be enabled/disabled on screen of the multi-information display. All of the Parking Support Brake functions (static objects and rear-crossing vehicles) are enabled/disabled simultaneously. (Settings display) When the Parking Support Brake is disabled, the PKSB OFF indicator (Indicators) illuminates on the multi-information display. To re-enable the system, select on the multi-information display, select and turn it on. If the system is disabled, it will remain off even if the engine switch is turned to ON after the engine switch has been turned off. Display and buzzer for engine output restriction control and brake control If the engine output restriction control or brake control operates, a buzzer will sound and a message will be displayed on the multi-information display, navigation system (if equipped) or multimedia system (if equipped) screen, to alert the driver. Depending on the situation, engine output restriction control will operate to either limit acceleration or restrict output as much as possible. Engine output restriction control is operating (acceleration restriction) Acceleration greater than a certain amount is restricted by the system. Navigation system (if equipped) or multimedia system (if equipped) screen: No warning displayed Multi-information display: “ Object Detected Acceleration Reduced” PKSB OFF indicator: Not illuminated Buzzer: Does not sound Engine output restriction control is operating (output restricted as much as possible) The system has determined that stronger-than-normal brake operation is necessary. Navigation system (if equipped) or multimedia system (if equipped) screen: “ BRAKE!” Multi-information display: “ BRAKE!” PKSB OFF indicator: Not illuminated Buzzer: Short beep Brake control is operating The system determined that emergency braking is necessary. Navigation system (if equipped) or multimedia system (if equipped) screen: “ BRAKE!” Multi-information display: “ BRAKE!” PKSB OFF indicator: Not illuminated Buzzer: Short beep Vehicle stopped by system operation The vehicle has been stopped by brake control operation. Navigation system (if equipped) or multimedia system (if equipped) screen: “ Press Brake Pedal” Multi-information display: “ Switch to Brake” (If the accelerator pedal is not depressed, “ Brake” will be displayed.) PKSB OFF indicator: Illuminated Buzzer: Short beep System overview If the Parking Support Brake determines that a collision with a detected object is possible, the engine output will be restricted to restrain any increase in the vehicle speed. (Engine output restriction control: See figure 2.)Additionally, if the accelerator pedal continues to be depressed, the brakes will be applied automatically to reduce the vehicle speed. (Brake control: See figure 3.) Figure 1: When the PKSB (Parking Support Brake) is not operating Engine output Braking force Time Figure 2: When engine output restriction control operates Engine output Braking force Time Engine output restriction control begins operating (System determines that possibility of collision with detected object is high) Figure 3: When engine output restriction control and brake control operates Engine output Braking force Time Engine output restriction control begins operating (System determines that possibility of collision with detected object is high) Brake control begins operating (System determines that possibility of collision with detected object is extremely high) Note: If the Parking Support Brake has operated If the vehicle is stopped due to operation of the Parking Support Brake, the Parking Support Brake will be disabled and the PKSB OFF indicator will illuminate. If the Parking Support Brake operates unnecessarily, brake control can be canceled by depressing the brake pedal or waiting for approximately 2 seconds for it to automatically be canceled. Then, the vehicle can be operated by depressing the accelerator pedal. Re-enabling the Parking Support Brake To re-enable the Parking Support Brake when it is disabled due to operation of the Parking Support Brake, either enable the system again (Enabling/Disabling the Parking Support Brake), or turn the engine 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 direction 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. PKSB (Parking Support Brake) Warning message Parking Support Brake (PKSB) Warning message If “ PKSB Unavailable” is displayed on the multi-information display and the PKSB OFF indicator is flashing If the vehicle is stopped due to operation of the Parking Support Brake, the Parking Support Brake will be disabled and the PKSB OFF indicator will illuminate. If “ Parking Assist Unavailable Clean Parking Assist Sensor” is simultaneously displayed, a sensor may be covered with ice, snow, dirt, etc. In this case, remove the ice, snow, dirt, etc., from the sensor to return the system to normal. If this message is shown even after removing dirt from the sensor, or shown when the sensor was not dirty to begin with, have the vehicle inspected at your Toyota dealer. A sensor may be frozen. Once the ice melts, the system will return to normal. Water may be continuously flowing over the sensor surface, such as in a heavy rain. When the system determines that it is normal, the system will return to normal. Initialization may not have been performed after a battery terminal was disconnected and reconnected. Initialize the system. (If a battery terminal has been disconnected and reconnected)If this message continues to be displayed even after initialization, have the vehicle inspected by your Toyota dealer. Initialization Parking Support Brake If a battery terminal has been disconnected and reconnected The system needs to be initialized. To initialize the system, drive the vehicle straight ahead for 5 seconds or more at a speed of approximately 22 mph (35 km/h) or more.
