1997 Lexus GS 300 User Guide 3 - Page 15

STARTING AND DRIVING Setting at a desired speed 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. Resetting to a faster speed Press the control lever upward in the "RES/ACC" direction and hold it. Release the lever when the desired speed is attained. While the lever is held upward, the vehicle will gradually gain speed. When the difference between the actual vehicle speed and the set speed is less than 5 km/h (3 mph), the set speed can be increased 1.6 km/h (1 mph) each time by pressing the control lever upward in the "RES/ACC" direction quickly within 0.6 seconds. However, a quicker way to reset is to accelerate the vehicle and then press the control lever downward in the "SET/COAST" direction. The transmission must be in "D" 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. Cancelling the preset speed You can cancel the preset speed by any of the following: c. Pulling the control lever in the "CANCEL" direction. d. Depressing the brake pedal. Resetting to a slower speed Press the control lever downward in the "SET/COAST" direction and hold it. Release the lever when the desired speed is attained. While the lever is held downward, the vehicle speed will gradually decrease. 145
