1998 Lexus GS 300 Owners Manual - Page 295

STARTING AND DRIVING Setting at a desired speed 31G012-1 The transmission must be in "D" or "4" before you set the cruise control speed. Bring the vehicle to the desired speed, press the control lever downward in the "SET/COAST" direction and release it. This sets the vehicle at that speed. Now you may take your foot off the accelerator pedal. If you need acceleration - for example, when passing - depress the accelerator pedal enough for the vehicle to exceed the set speed. When you release the accelerator pedal, the vehicle will return to the speed set prior to the acceleration. If the vehicle speed falls below about 40 km/h (25 mph), the preset speed will be automatically cancelled. If the vehicle speed drops 16 km/h (10 mph) below the preset speed, the preset speed will also automatically be cancelled. If the preset speed automatically cancels out for other than these reasons, have your vehicle checked by your Lexus dealer at the earliest opportunity. Cancelling the preset speed You can cancel the preset speed by either of the following: a. Pulling the control lever in the "CANCEL" direction. b. Depressing the brake pedal. 282
