Following the launch of the new IS saloon, Lexus is giving customers the opportunity to add a suite of advanced safety features and driving aids to their vehicle with an additional option pack.

Available exclusively for the flagship Premier versions of the new IS 250 and full hybrid IS 300h, the £1,540 pack adds Pre-Crash Safety system (PCS), Adaptive Cruise Control (ACC), Lane Departure Assist (LDA), Automatic High Beam (AHB) and the Pre-Crash Safety system.

The PCS system uses a millimetre-wave radar sensor that operates over a 20-degree scanning radius to detect obstacles in the vehicle’s path, even when cornering.

If there is a high risk of a collision, PCS will alert the driver with a buzzer and warning on the multimedia display, activate the Pre-Crash Seatbelt pretensioners, and, when the driver begins to brake, provide Pre-Crash Brake Assist to supplement the braking effort. If the driver does not brake and a collision becomes inevitable, the Pre-Crash Brake will automatically apply the brakes to reduce impact speed.

The Adaptive Cruise Control can operate on a set constant speed or monitor the speed of the car in front and keep a prescribed distance, braking and accelerating safely and automatically.

The Lane Departure Alert system monitors road markings using a camera mounted on the rear-view mirror. If it detects the vehicle is deviating from its lane without the turn signals being used, it alerts the driver by sounding a buzzer and showing a warning on the instrument display.

The Automatic High Beam function for the headlamps maximises night-time visibility by automatically switching to low beam when the system’s camera detects the lights of an oncoming vehicle, or one travelling ahead. This means the high beam can be used for the safe maximum amount of time.
