Toyota Safety Sense

Crash protection starts with crash prevention. Collisions that result in injury may be caused by the delay in a driver’s recognition of the situation and their ability to react accordingly. According to NHTSA1, there werealmost 5.7 million reported crashes in 2014—many of which were avoidable.

Toyota Safety Sense™ (TSS)2 is designed to help protect drivers, passengers, people in other vehicles on the road and pedestrians (TSS-P2 and AHB7) from harm. TSS2 is comprised of advanced active safety packages anchored by automated pre-collision warning3 and braking. TSS2 represents the latest milestone in our long history of creating advancements and innovations in safety that have helped prevent crashes and protect people.

TSS2 is designed to support driver awareness, decision making and vehicle operation over a wide range of speeds under certain conditions. Packaged together in an integrated system, TSS2 features help address three key areas of accident protection: preventing or mitigating frontal collisions3, keeping drivers within their lane6, and enhancing road safety during nighttime driving7. Always drive safely, obey traffic speed limits and laws and focus on the road while driving. TSS2 will be offered on certain vehicles in the form of two packages:

  • Toyota Safety Sense™ C2 [TSS-C] for compact vehicles
  • Toyota Safety Sense™ P2 [TSS-P] for mid-sized and large vehicles

Vehicle Detection

With Toyota Safety Sense™ C2, PCS3 uses an in-vehicle camera and laser to help detect the vehicle in front of your vehicle. As there is a limit to the degree of recognition accuracy and control performance that this system can provide, do not overly rely on this system. This system will not prevent collisions or lessen collision damage or injury in every situation. Do not use PCS3 instead of normal braking operations under any circumstances. Do not attempt to test the operation of the pre-collision system yourself, as the system may not operate or engage, possibly leading to an accident. In some situations such as when driving in inclement weather (heavy rain, fog, snow, sandstorm, etc.) or while driving on a curve and for a few seconds after driving on a curve, a preceding vehicle may not be detected by the laser and camera sensors, preventing the system from operating properly.



Refer to a Toyota Owner's Manual for additional information on PCS2 operation, setting adjustments, limitations and precautions.

Lane Departure Alert

LDA6 uses an in-vehicle camera designed to detect visible white and yellow lane markers in front of the vehicle and the vehicle’s position on the road. If the system 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.

As there is a limit to the degree of recognition accuracy and control performance that this system can provide, do not overly rely on this system. This system will not alert the driver of or help prevent unintentional lane departures in every situation. Do not use LDA instead of normal steering operations under any circumstances. In some situations, such as when driving in inclement weather such as heavy rain, fog, snow or a sandstorm or while driving on a curve and for a few seconds after driving on a curve, visible lane markers may not be detected by the camera sensor, preventing the system from operating or engaging properly.

Auto High Beams

AHB7 is a safety system designed to help drivers see more of what’s ahead at nighttime without dazzling other drivers. When enabled, Automatic High Beams7 uses an in-vehicle camera to help detect the headlights of oncoming vehicles and tail lights 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.

As there is a limit to the degree of recognition accuracy and control performance that this system can provide, do not overly rely on this system. This system will not cycle headlights between low and high beam in every situation. In some situations, such as when driving in inclement weather such as heavy rain, fog, snow or a sandstorm or while driving on a curve and for a few seconds after driving on a curve, forward lights may not be detected by the camera sensor, preventing the system from operating or engaging properly.

Dynamic Radar Cruise Control

On highways or expressways, Dynamic Radar Cruise Control10 functions similar 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 pre-set distance to a preceding vehicle when the preceding vehicle is traveling at a lower speed.

Once a vehicle speed is set by the driver, Dynamic Radar Cruise Control10 uses a front-grill 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 and 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.

As there is a limit to the degree of recognition accuracy and distance/deceleration control performance that this system can provide, do not overly rely on this system. This system will not operate in every situation. In some situations, such as when driving in inclement weather such as heavy rain, fog, snow or a sandstorm or while driving on a curve and for a few seconds after driving on a curve, a preceding vehicle may not be detected by the camera/radar sensors, preventing the system from operating or engaging properly.

Pedestrian Detection

As there is a limit to the degree of recognition accuracy and control performance that this system can provide, do not overly rely on this system. This system will not prevent collisions or lessen collision damage or injury in every situation. Do not use PCS3 instead of normal braking operations under any circumstances. Do not attempt to test the operation of the pre-collision system3 yourself, as the system may not operate or engage, possibly leading to an accident. In some situations such as when driving in inclement weather (heavy rain, fog, snow,sandstorm, etc.) or while driving on a curve and for a few seconds after driving on a curve, a preceding vehicle/pedestrian may not be detected by the radar and camera sensors, preventing the system from operating properly.
