2006 Lexus GS 300 Owners Manual - Page 1056

STARTING AND DRIVING In the following cases, the warning messages appear and the preset speed automatically cancels out. When dynamic radar cruise control is restored, the warning messages turn off and dynamic radar cruise control enters "RADAR READY" mode. a. The slip indicator light blinks and a warning tone sounds. (This occurs when the vehicle is about to skid.) b. The driving pattern selector switch is set to snow mode. c. The anti−lock brake system is activated by automatic braking. (The warning tone sounds.) d. The sensor does not operate properly because a foreign matter sticks to the sensor. e. The wipers are operated at high speed (including high speed operation with the wiper lever in the "AUTO" position.) 3 Resetting to a faster speed Press the control lever upward in the "+ RES" direction and hold it. The displayed speed will increase in increments of 5 mph (for the U.S.A.) or 5 km/h (for Canada). Release the lever when the desired speed is attained. The vehicle will gradually increase to the displayed speed. Depressing the accelerator pedal and pressing the control lever downward in the "- SET" direction will not reset to a faster speed. At this time the set speed falls by 5 mph (for the U.S.A.) or 5 km/h (for Canada). CAUTION When the vehicle−to−vehicle distance control is on (on follow−up cruising), your cruising speed is regulated in proportion to the speed of the vehicle ahead, so increasing the preset vehicle speed using the control lever does not accelerate the vehicle. However, if the vehicle ahead leaves the lane, your cruising speed will increase up to the preset speed because the preset speed has been set higher using the control lever. Confirm the setting on the multi−information display. NOTICE If the preset speed automatically cancels out for other than the above reasons, do not operate the dynamic radar cruise control. Although it is no problem to continue driving, have your vehicle checked by your Lexus dealer at the earliest opportunity. 410
