Intelligent and Powerful Lexus Brakes

Enhanced braking performance in both Lexus GS sedans begins with mechanical components that significantly increase brake friction and improve stopping power, while effectively eliminating brake fade. Lexus Brake Assist (BA), Electronic Brake-force Distribution (EBD) and the Anti-lock Braking System (ABS) help form a powerful safety front. EBD optimizes brake pressure at each wheel to help minimize body dive or sway during hard braking and cornering. Brake Assist is designed to determine if the driver is attempting emergency braking and, if the driver has not stepped firmly enough on the brake pedal to activate the ABS, it will apply maximum braking force until pedal pressure is released.

Lexus GS 430's Electronically Controlled Brakes (ECB) is a brake-by-wire system. ECB translates brake pedal pressure into electric signals that, via computer control, help provide precise and optimized braking in virtually any traction condition. Electronic control provides quick brake response when needed, helping the GS 430's VDIM system to anticipate and help correct skids before they occur. Lexus ECB system is backed by conventional hydraulic brake control in the unlikely event of electronic failure.

Lexus designers strive to keep controls simple and intuitive, avoiding needless complexity. A secure and distraction-free setting enables the driver to best appreciate the GS' enhanced performance. The SmartAccess keyless entry and push-to-start ignition allow the driver to keep the access fob in a pocket or purse. Audio and climate-control systems are easy to understand and operate, and the GS locates controls that are used less frequently behind a dash panel on the left side of the steering wheel.

The gauge cluster features machined aluminum facings for a classic look. Highlighting the sporty nature of the GS and emphasizing a closer driver-and-machine connection, the quick-response tachometer moves more directly in concert with changes in engine rpm. The unique instrument panel lighting system relies on variable-transparency glass to minimize reflections from the gauge faces and to help optimize visibility in all lighting conditions.

A comprehensive interior lighting system provides just the right amount of light where the driver and passengers need it. All four windows offer one-touch up-and-down operation with jam protection. Both electrochromic auto-dimming side mirrors are power-retractable and feature automatic tilt-down when reverse gear is selected to aid in parking. A power trunk closer provides a finishing touch on this extremely well-equipped car.


Advanced Safety Systems

Both GS Lexus models implement a variety of advanced safety systems. The Supplemental Restraint System (SRS) includes variable-force front airbags for both driver and front passenger. Sensors determine the severity of an impact and in turn the airbag deployment force, helping to provide an appropriate level of occupant restraint. The GS features standard seat-mounted side airbags for the front seats, knee airbags for the driver and front passenger, and front and rear side-curtain airbags.

The optional Pre-Collision System (PCS) in the Lexus GS models can help reduce collision damage. A millimeter-wave radar sensor helps detect obstacles in front of the car, while vehicle speed, steering angle and yaw-rate inputs help to determine whether a collision is unavoidable.

In such a situation, PCS in Lexus switches the Adaptive Variable Suspension to sport mode for optimal chassis response, preemptively retracts front seat belts, and preinitializes Brake Assist so that increased braking will be applied the instant the driver depresses the pedal. The active braking feature will automatically apply the brakes up to a deceleration rate of 0.3 G's if the driver fails to react to system warnings.
