| Feature | Description | Availability (Varies by Model/Year) |
|---|---|---|
| Pre-Collision System (PCS) | Uses a radar and camera system to detect vehicles, pedestrians, and cyclists in front of the car. If a collision is imminent, it provides an audible and visual warning to the driver. If the driver doesn't react in time, the system can automatically apply the brakes to reduce the severity of the impact or avoid the collision altogether. Some versions include pedestrian and cyclist detection, even in low-light conditions. | Standard or optional on most Toyota models, with variations in functionality. Newer versions offer more sophisticated detection capabilities and wider operating ranges. |
| Lane Departure Alert (LDA) | Employs a camera to monitor the vehicle's position within its lane. If the system detects that the vehicle is drifting out of its lane without the turn signal activated, it provides an audible and visual warning. Some versions include Steering Assist, which gently corrects the vehicle's steering to help keep it within the lane. LDA is designed to prevent unintentional lane departures, which can be a significant cause of accidents. | Standard or optional on most Toyota models. Steering Assist is often included in newer versions. The sensitivity of the system can often be adjusted by the driver. |
| Automatic High Beams (AHB) | Automatically switches between high and low beams based on the presence of other vehicles. The system uses a camera to detect headlights and taillights of oncoming or preceding vehicles. When no other vehicles are detected, the system activates the high beams for optimal visibility. When another vehicle is detected, the system automatically switches to low beams to avoid blinding the other driver. AHB enhances nighttime driving safety and convenience. | Standard or optional on most Toyota models. It significantly improves visibility during nighttime driving and reduces the risk of accidents. |
| Dynamic Radar Cruise Control (DRCC) | Maintains a preset speed and following distance from the vehicle ahead. The system uses a radar sensor to monitor the distance to the preceding vehicle and automatically adjusts the vehicle's speed to maintain the set following distance. If the vehicle ahead slows down or stops, the system will automatically slow down or stop the vehicle as well. DRCC reduces driver fatigue on long drives and helps maintain a safe following distance. Full-Speed Range DRCC can operate from 0 mph, allowing for stop-and-go traffic. | Standard or optional on most Toyota models. Full-Speed Range DRCC is typically available on newer models. The driver can adjust the following distance in most versions. |
| Lane Tracing Assist (LTA) | Works in conjunction with Dynamic Radar Cruise Control to help keep the vehicle centered in its lane. The system uses the lane markings and/or the preceding vehicle to provide steering assistance, reducing driver fatigue and enhancing lane keeping performance. LTA is designed to make long drives more comfortable and less stressful. It requires Dynamic Radar Cruise Control to be engaged. | Typically available on newer Toyota models equipped with Dynamic Radar Cruise Control. LTA provides a more active lane keeping function than Lane Departure Alert with Steering Assist. |
| Road Sign Assist (RSA) | Uses a forward-facing camera to detect speed limit signs, stop signs, yield signs, and other road signs. The system displays the detected signs on the multi-information display, helping the driver stay aware of the current traffic regulations. RSA enhances driver awareness and reduces the risk of unintentionally violating traffic laws. | Often available on newer Toyota models. It provides a valuable reminder of important traffic signs. |
| Blind Spot Monitor (BSM) | Uses radar sensors to detect vehicles in the driver's blind spots. If a vehicle is detected in a blind spot, the system provides a visual warning in the corresponding side mirror. Some systems also include Rear Cross-Traffic Alert (RCTA), which alerts the driver to approaching vehicles from the sides when backing up. BSM and RCTA enhance situational awareness and reduce the risk of collisions when changing lanes or backing out of parking spaces. | Typically optional and available on many Toyota models. BSM and RCTA are often bundled together. |
| Rear Cross-Traffic Alert (RCTA) | Alerts the driver to approaching vehicles from the sides when backing up, especially useful in parking lots. The system uses radar sensors to detect vehicles approaching from either side and provides an audible and visual warning. RCTA helps prevent collisions when backing out of parking spaces with limited visibility. | Typically optional and often bundled with Blind Spot Monitor (BSM). |
| Parking Assist with Automatic Braking (PAwAB) | Uses sensors to detect objects around the vehicle while parking. If the system detects a potential collision, it can automatically apply the brakes to help prevent or mitigate the impact. PAwAB enhances parking safety and reduces the risk of low-speed collisions. | Typically optional and available on some newer Toyota models. |
| Proactive Driving Assist (PDA) | Uses the vehicle’s camera and radar to provide gentle braking into curves or gentle braking and/or steering to help support driving tasks such as distance control between your vehicle and a preceding vehicle, pedestrian, or bicyclist. | Available on some newer Toyota models. |
Detailed Explanations
Pre-Collision System (PCS): This system is designed to detect potential frontal collisions. It uses a combination of radar and cameras to monitor the road ahead. When it identifies a potential collision with a vehicle, pedestrian, or cyclist, it provides an audible and visual warning to the driver. If the driver doesn't react in time, the system can automatically apply the brakes to help reduce the severity of the impact or even avoid the collision altogether. Modern versions often include enhanced pedestrian and cyclist detection, even in low-light conditions.
Lane Departure Alert (LDA): LDA utilizes a camera to monitor the vehicle's position within its lane. If the system detects that the vehicle is drifting out of its lane without the turn signal being activated, it provides an audible and visual warning to the driver. Newer versions often incorporate Steering Assist, which gently corrects the vehicle's steering to help keep it within the lane. This feature is particularly useful in preventing unintentional lane departures, which can be a major cause of accidents.
Automatic High Beams (AHB): This system automatically switches between high and low beams based on the presence of other vehicles. The system uses a camera to detect the headlights and taillights of oncoming or preceding vehicles. When no other vehicles are detected, the system activates the high beams for optimal visibility. When another vehicle is detected, the system automatically switches to low beams to avoid blinding the other driver. AHB enhances nighttime driving safety and convenience by providing optimal illumination without requiring the driver to manually switch the headlights.
Dynamic Radar Cruise Control (DRCC): DRCC maintains a preset speed and following distance from the vehicle ahead. The system uses a radar sensor to monitor the distance to the preceding vehicle and automatically adjusts the vehicle's speed to maintain the set following distance. If the vehicle ahead slows down or stops, the system will automatically slow down or stop the vehicle as well. Full-Speed Range DRCC can operate from 0 mph, allowing for stop-and-go traffic, making it particularly useful in congested traffic conditions. The driver can typically adjust the following distance to their preference.
Lane Tracing Assist (LTA): LTA works in conjunction with Dynamic Radar Cruise Control to help keep the vehicle centered in its lane. The system uses lane markings and/or the preceding vehicle to provide steering assistance, reducing driver fatigue and enhancing lane-keeping performance. LTA is designed to make long drives more comfortable and less stressful. It requires Dynamic Radar Cruise Control to be engaged to function.
Road Sign Assist (RSA): RSA uses a forward-facing camera to detect speed limit signs, stop signs, yield signs, and other road signs. The system displays the detected signs on the multi-information display, helping the driver stay aware of the current traffic regulations. RSA enhances driver awareness and reduces the risk of unintentionally violating traffic laws. It provides a valuable reminder of important traffic signs.
Blind Spot Monitor (BSM): BSM utilizes radar sensors to detect vehicles in the driver's blind spots. If a vehicle is detected in a blind spot, the system provides a visual warning in the corresponding side mirror. Some systems also include Rear Cross-Traffic Alert (RCTA), which alerts the driver to approaching vehicles from the sides when backing up. BSM and RCTA enhance situational awareness and reduce the risk of collisions when changing lanes or backing out of parking spaces.
Rear Cross-Traffic Alert (RCTA): RCTA alerts the driver to approaching vehicles from the sides when backing up, especially useful in parking lots. The system uses radar sensors to detect vehicles approaching from either side and provides an audible and visual warning. RCTA helps prevent collisions when backing out of parking spaces with limited visibility.
Parking Assist with Automatic Braking (PAwAB): This system uses sensors to detect objects around the vehicle while parking. If the system detects a potential collision, it can automatically apply the brakes to help prevent or mitigate the impact. PAwAB enhances parking safety and reduces the risk of low-speed collisions.
Proactive Driving Assist (PDA): This system uses the vehicle’s camera and radar to provide gentle braking into curves or gentle braking and/or steering to help support driving tasks such as distance control between your vehicle and a preceding vehicle, pedestrian, or bicyclist. It adds an extra layer of safety during everyday driving.
