2022 Toyota Corolla Cross Owners Manual - RSA (Road Sign Assist)

RSA (Road Sign Assist)

The RSA system detects specific road signs using the front camera and/or navigation system (when speed limit information is available) and warns the driver via displays and buzzers.

WARNING

■For safe use

• Driving safely is solely the responsibility of the driver. Pay careful attention to the surrounding conditions in order to ensure safe driving.
• Do not rely solely upon the RSA. The RSA assists the driver by providing road sign information, but it is not a replacement for the driver's own vision and awareness. Driving safely is solely the responsibility of the driver. Pay careful attention to the surrounding conditions in order to ensure safe driving.

■Situations in which the RSA should not be used

• When it is necessary to disable the system

■Situations in which the system may not operate properly

• Situations in which the sensors may not operate properly

Display Function

• When the front camera detects a sign or information of a sign is available from the navigation system, the sign will be displayed on the display.
• Multiple signs can be displayed.

Depending on the specifications of the vehicle, the number of displayed signs may be limited.

■Operating conditions of sign display

Signs will be displayed when the following conditions are met:

• The system has detected a sign

In the following situations, a displayed sign may stop being displayed:

• When a new sign has not been detected for a certain distance
• When the system determines that the road being driven on has changed, such as after a left or right turn

■Situations in which the display function may not operate properly

In the following situations, the RSA system may not operate properly and may not detect signs or may display the incorrect sign. However, this does not indicate a malfunction.

• When a sign is dirty, faded, tilted or bent
• When the contrast of an electronic sign is low
• When all or part of a sign is hidden by a tree, utility pole, etc.
• When a sign is detected by the front camera for a short amount of time
• When the driving state (turning, changing lanes, etc.) is judged incorrectly
• When a sign is immediately after a freeway junction or in an adjacent lane just before merging
• When stickers are attached to the rear of a preceding vehicle
• When a sign similar to a system compatible sign is detected as a system compatible sign
• When a speed limit sign for a frontage road is within detection range of the front camera
• When driving around a roundabout
• When a sign intended for trucks, etc. is detected
• When the navigation system map data is out of date
• When the navigation system cannot be used

In this case, the speed limit signs displayed on the multi-information display and navigation system display may differ.

Notification function

In the following situations, the RSA system will output a warning to notify the driver.

• If the vehicle speed exceeds the speed warning threshold of the speed limit sign displayed on the display, the sign display will be emphasized and a buzzer will sound.
• When the RSA system detects a do not enter sign and determines that the vehicle has entered a no-entry area, the do not enter sign displayed on the display will flash and a buzzer will sound.

■Operating conditions of the notification functions

• Excess speed notification function

This function will operate when the following condition is met:

• A speed limit road sign is recognized by the system.

• No entry notification function

This function will operate when all of the following conditions are met:

• More than one no entry road signs are recognized by the system simultaneously.
• The vehicle is passing between no entry road signs recognized by the system.

Types of road signs supported

• The following types of road signs can be displayed.

However, non-standard or recently introduced traffic signs may not be displayed.

  Speed limit

  Speed limit

 Do Not Enter

   No U-turn

  No Turn On Red

  Stop

  Yield

 Warning

• Depending on the specifications of the vehicle, signs may be displayed overlapping.

  Duplicate display example

  Duplicate display example

Changing RSA settings

The following settings of the RSA can be changed through customize settings.

Dynamic radar cruise control

This dynamic radar cruise control detects the presence of vehicles ahead, determines the current vehicle- to-vehicle distance, and operates to maintain a suitable distance from the vehicle ahead. The desired vehicle-to-vehicle distance can be set by operating the vehicle-to-vehicle distance switch.

Use the dynamic radar cruise control only on highways and expressways.

WARNING

■For safe use

• Driving safely is solely the responsibility of the driver. Do not overly rely on this system, and pay careful attention to the surrounding conditions in order to ensure safe driving.
• The dynamic radar cruise control provides driving assistance to reduce the driver's burden.

  However, there are limitations to the assistance provided.

Read the following items carefully.

Do not overly rely on this system and always drive carefully.

Conditions under which the system may not operate correctly.

• Set the speed appropriately according to the speed limit, traffic flow, road conditions, weather conditions, etc. The driver is responsible for confirming the set speed.
• Even if the system is operating correctly, the condition of a preceding vehicle as recognized by the driver and detected by the system may differ. Therefore, it is necessary for the driver to pay attention, assess risks, and ensure safety. Over-reliance on this system to drive the vehicle safely may lead to an accident resulting in death or serious injury.

■Precautions for the driving assist systems

Observe the following precautions, as there are limitations to the assistance provided by the system. Over-reliance on this system may lead to an accident resulting in death or serious injury.

• Details of support provided for the driver's vision

The dynamic radar cruise control is only intended to help the driver in determining the distance between the driver's own vehicle and a designated preceding vehicle.

It is not a system which allows for careless or inattentive driving, and is not a system which assists in poor visibility conditions.

The driver must pay attention to their surroundings, even when the vehicle stops.

• Details of support provided for the driver's judgement

The dynamic radar cruise control determines whether the distance between the driver's own vehicle and a designated preceding vehicle is within a set range. It is not capable of making any other type of judgement. Therefore, it is absolutely necessary for the driver to remain vigilant and to determine whether or not there is a possibility of danger.

• Details of support provided for the driver's operation

The dynamic radar cruise control does not include functions which will prevent or avoid collisions with vehicles ahead of your vehicle.

Therefore, if there is ever any possibility of danger, the driver must take immediate and direct control of the vehicle and act appropriately in order to ensure safety.

■Situations in which the dynamic radar cruise control should not be used

Do not use the dynamic radar cruise control in the following situations.

As the system will not be able to provide appropriate control, using it may lead to an accident resulting in death or serious injury.

• Roads where there are pedestrians, cyclists, etc.
• When driving on a highway or expressway entrance or exit
• When the approach warning sounds frequently
• Situations in which the sensors may not operate properly.
• Situations in which the lane may not be detected
