Toyota Safety Sense's Pre-Collision System uses a camera and laser to detect other vehicles in the road ahead. When the possibility of collision is detected the driver is alerted with audio and visual warnings and brake assistance is activated. If the driver fails to brake in time the brakes automatically engage to prevent or mitigate a collision.
Using a camera to detect the lane markings in the road ahead, Toyota Safety Sense's Lane Departure Alert will give the driver audible and visual warnings if the vehicle starts to deviate from its lane without the turn indicator being applied – the driver can then take corrective action.
HAC helps to ensure a smooth start on steep inclines by applying the brakes for up to 2 seconds after the brake pedal is released. This prevents the vehicle from rolling back. It is activated by pushing the brake pedal harder after stopping as long as the transmission shift lever is in any forward gear position.
The system features a sensor valve within each wheel to constantly monitor tyre air pressure. These sensors link with a dashboard indicator that illuminates to warn you if the pressure falls below the recommended level. By doing so, the system contributes to safer driving, better tyre wear and greater fuel efficiency.
