OPTION: Lexus IS 300h offers pack option

Lexus IS customers will have the opportunity to add an advanced safety feature and driving aid suite to their vehicle, with an additional option pack.

The pack – a built-to-order option priced £1,540 – is exclusive to the flagship Premier versions of the new IS 250 and full hybrid IS 300h, and provides four additional systems.

Systems included are: a Pre-Crash Safety system (PCS); Adaptive Cruise Control (ACC); Lane Departure Assist (LDA); and Automatic High Beam (AHB).

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.

Using a number of sensors, a pre-collision computer monitors vehicle speed, steering angle and yaw rate inputs to help determine whether an impending collision is unavoidable.

Upon high risk of a collision, PCS alerts the driver with a buzzer and warning on the multimedia display, activating the Pre-Crash Seatbelt pretensioners.

When the driver begins to brake, it will also 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 works in two modes: constant speed control and vehicle-to-vehicle distance control.

Working at speeds above 31mph, the constant speed control operates just like a conventional cruise control system.

The vehicle-to-vehicle distance control can differentiate between vehicles directly ahead, and those in an adjacent lane.

It uses the PCS millimetre-wave radar sensor, allied to constant speed, decelerator, follow-up and accelerator controls, to automatically match the speed of the vehicle in front.

Once the road ahead is clear, it will accelerate back to the previously selected cruising speed.

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 turn signals, it sounds a buzzer and shows a warning on the instrument display.

Finally, the headlamp Automatic High Beam function maximises night-time visibility by automatically switching to low beam when the system’s camera detects lights of an oncoming vehicle, or one travelling ahead.

This means the high beam can be used for the safe maximum amount of time.
