2006 Lexus GS 300 Owners Manual - Page 1095

STARTING AND DRIVING If the tire pressure select switch is set to the wrong tire setting, the system will not work properly. After about 1 hour, the tire pressure warning light blinks to indicate a system malfunction. PRE−COLLISION SYSTEM (Vehicles with dynamic radar cruise control) When the pre−collision system detects what it perceives to be an unavoidable collision, the front seat belts are quickly drawn back by the retractors (pre−collision seat belts) and more powerful braking is applied according to the amount of pedal depression to help reduce injury to the occupants and damage to the vehicle body. In addition, the adaptive variable suspension works to help regulate the vehicle not to pitch forward so much. The pre−collision system will operate when the engine switch is selected in "IG−ON" mode. 449
