What is Toyota Safety Sense?
Toyota Safety Sense was developed to help protect drivers, passengers and pedestrians (TSS-P only) from harm. TSS is comprised of multi-feature active safety packages anchored by automated pre-collision warning and braking and is offered in the form of two packages:
|Toyota Safety Sense P (TSS-P)
Midsize & Large Vehicles
|Toyota Safety Sense C (TSS-C)
|Pre-Collision System (PCS)|
|Lane Departure Alert (LDA)|
|Auto High Beams (AHB)|
|Pedestrian Pre-Collision Alert (PCS w/ PD)|
|Dynamic Radar Cruise Control (DRCC)|
TOYOTA SAFETY SENSE™ (TSS)
Together we can help make the road safe.
The road can be unpredictable. That’s why we created available Toyota Safety Sense™ : to help protect drivers, passengers and pedestrians (TSS-P only) from harm. Toyota Safety Sense™ (TSS) is designed to help protect drivers, passengers, people in other vehicles on the road, and pedestrians (TSS-P and AHB). TSS is comprised of multi-feature active safety packages anchored by automated pre-collision warning and braking. TSS is designed to support the driver's awareness, decision-making and vehicle operation over a wide range of speeds under certain conditions. Packaged together in an integrated system, TSS features help address three key areas of accident protection: mitigating or preventing frontal collisions, helping to keep drivers within their lane, and enhancing road safety during nighttime driving. Always drive safely, obey traffic speed limits and laws, and focus on the road while driving.
TSS will be offered in the form of two packages: Toyota Safety Sense™ C (TSS-C) for compact vehicles and Toyota Safety Sense™ P (TSS-P) for midsize and large vehicles.
Toyota Safety Sense™ C features three proprietary active safety technologies, and combines a camera and laser for outstanding performance and reliability. The package can help mitigate or prevent collisions in a wide range of vehicle speeds under certain conditions.
• Pre-Collision System (PCS) — Vehicle Detection
• Lane Departure Alert (LDA)
• Automatic High Beams (AHB)
Toyota Safety Sense™ P combines an in-vehicle camera and front-grille-mounted, millimeter-wave radar for enhanced performance and more functionality.
• Pre-Collision System with Pedestrian Detection function (PCS w/PD) —Vehicle Detection & Pedestrian Detection
• Lane Departure Alert with Steering Assist function (LDA w/SA) (EPS-equipped vehicles)
• Automatic High Beams (AHB)
• Dynamic Radar Cruise Control (DRCC)
See Owner’s Manual for additional details on system operations, limitations, and precautions.
Pre-Collision System (PCS)
With TSS-C, Pre-Collision System (PCS) uses an in-vehicle camera and laser to help detect the vehicle in front of your vehicle. When PCS determines that the possibility of a frontal collision with that vehicle is high, it prompts the driver to take evasive action and brake, by using an audio and visual alert. If the driver notices the hazard and brakes, the system may provide additional braking force using Brake Assist. If the driver does not brake in a set time and the system determines that the possibility of a frontal collision with a preceding vehicle is extremely high, the system may automatically apply the brakes, reducing speed in order to help the driver reduce the impact and in certain cases avoid the collision.
Lane Departure Alert (LDA)
If Lane Departure Alert determines that the vehicle is starting to unintentionally deviate from its lane, the system alerts the driver with an audio and visual alert. When the alerts occur, the driver must check the surrounding road situation and carefully operate the steering wheel to move the vehicle back to the center part of their lane.
LDA is designed to function at speeds of approximately 32 mph or higher on relatively straight roadways.
In addition to the alert functions of LDA, TSS-P equipped vehicles with Electronic Power Steering (EPS) will also feature a Steering Assist function (LDA w/SA). When equipped and enabled, if the system determines that the vehicle is on a path to unintentionally depart from its lane, the system may provide small corrective steering inputs to the steering wheel for a short period of time to help keep the vehicle in its lane.
Automatic High Beams (AHB)
Automatic High Beams (AHB), found in both TSS-C and TSS-P, is a safety system designed to help drivers see more of what's ahead at nighttime without dazzling other drivers. When enabled, AHB uses an in-vehicle camera to help detect the headlights of oncoming vehicles and taillights of preceding vehicles, then automatically switches between high and low beams as appropriate to provide the most light possible and enhance forward visibility. By using high beams more frequently, the system may allow earlier detection of pedestrians and obstacles.
AHB is designed to function at speeds of approximately 25 mph or higher. Minimum speed may vary by vehicle.
Pre-Collision System With Pedestrian Detection Function (PCS w/PD)
With Toyota Safety Sense™ P, PCS uses an in-vehicle camera and front-grille-mounted, millimeter-wave radar to help detect the vehicle in front of your vehicle.
In certain conditions, the PCS system included with the TSS-P package may also help to detect a pedestrian in front of your vehicle. The in-vehicle camera of PCS detects a potential pedestrian based on size, profile and motion of the detected pedestrian. However, a pedestrian may not be detected depending on the conditions, including the surrounding brightness and the motion, posture, size and angle of the potential detected pedestrian, preventing the system from operating or engaging. If PCS determines that the possibility of a frontal collision with a pedestrian in front of your vehicle is high under certain conditions, it prompts the driver to take evasive action and brake, by using an audio and visual alert. If the driver notices the hazard and brakes, the system may provide additional braking force using Brake Assist. If the driver does not brake in a set time and the system determines that the risk of collision with a pedestrian in front of your vehicle is extremely high, the system may automatically apply the brakes, reducing speed in order to help the driver reduce the impact and in certain cases avoid the collision.
Dynamic Radar Cruise Control (DRCC)
TSS-P equipped vehicles include Dynamic Radar Cruise Control (DRCC). On highways, DRCC functions similarly to conventional “constant speed” cruise control in that it helps vehicles travel at a consistent speed set by the driver, but this system adds a vehicle-to-vehicle distance control mode which assists the driver by adjusting vehicle speed (within a set range) to help maintain a preset distance to a preceding vehicle when the preceding vehicle is traveling at a lower speed.
Once a vehicle speed is set by the driver (approximately 28 mph or higher), DRCC uses a front-grille-mounted, millimeter-wave radar and an in-vehicle camera to detect a preceding vehicle and help determine its distance.
If the vehicle ahead is detected traveling at a speed slower than your set speed or within your distance range setting, the system is designed to automatically decelerate your vehicle without having to cancel the cruise control. When a greater reduction in vehicle speed is necessary, the system may apply the brakes, may alert the driver by using an audio and visual alert, and may operate your vehicle brake lights. The system will then respond to changes in the speed of the vehicle ahead in order to help maintain the vehicle-to-vehicle distance set by the driver. When there is no longer a preceding vehicle driving slower than your vehicle's set speed, the system accelerates until the set speed is reached and returns to constant speed cruising.
DRCC is designed to function at speeds of approximately 25 to 110 mph. However, vehicle speed must be above approximately 28 mph to initiate DRCC, as that is the lowest set speed.
Starting with certain 2016 Prius models, select Toyota vehicles may also feature the new Full-Speed Range DRCC, which is designed to also work at speeds below 25 mph. Full-Speed Range DRCC may enable low-speed following, speed matching, stopping and acceleration/deceleration to a preceding vehicle. Full-Speed Range DRCC is designed to function at speeds between approximately 0 to 110 mph and is intended for highway use.
