The new Lexus CT 200h may be equipped with a sophisticated Pre-Crash Safety system (PCS) that can help reduce collision damage and injury. It employs a millimetre wave radar sensor to detect objects ahead, recognising potentially dangerous objects ahead and assisting the driver in reducing the chances of a collision.

If there is a high possibility of a collision, PCS will alert the driver activate the Pre-Crash Seatbelt pretensioners and, when he begins to brake, provide Pre-Crash Brake Assist to supplement his own braking effort. If the driver does not brake and a collision is inevitable, Pre-Crash Brake will automatically apply the brakes to reduce impact speed.

Adaptive Cruise Control (ACC) works in tandem with PCS, at speeds between 50 and 170km/h. The system will automatically maintain a selected distance from the vehicle in front. Once the road ahead is clear, the CT 200h automatically returns to its original cruising speed.

Upgraded by Lexus engineers to offer improved braking feel and performance, the Lexus CT 200h is equipped with a second generation Electronically Controlled Braking-Regeneration system (ECB-R) which coordinates the control of both hydraulic and regenerative braking. This cooperative control system achieves excellent fuel economy by proactively using braking force from the hybrid drive system's electric motor to recover as much electrical energy as possible.

ECB-R incorporates the full range of active safety systems, including a latest generation Anti-lock Brake System (ABS) with Brake Assist, Traction Control (TRC) and Vehicle Stability Control (VSC).
