2006 Lexus RX 400h Owners Manual - Page 466

STARTING AND DRIVING Bring your vehicle to the desired speed, push the lever down in the "− SET" direction and release it. This sets the vehicle at that speed. At this time, the display indicates settings such as the preset vehicle speed, whether a vehicle is present ahead and the selected vehicle−to−vehicle distance. If no vehicle is detected ahead, the display does not indicate the vehicle ahead. You can now take your foot off the accelerator pedal. If you need to accelerate - for example, when passing - depress the accelerator pedal enough for the vehicle to exceed the preset speed. When you release the accelerator pedal, the vehicle will return to the control prior to acceleration. You cannot set the vehicle speed if the master warning light comes on, the alarm sounds and a warning message appears on the multi−information display. If a warning message appears on the display, see "(l) Vehicle−to−vehicle distance control mode failure warning" on page 436. (d) Cancelling the preset speed You can cancel the preset speed by doing any of the following: a. Pulling the lever in the "CANCEL" direction. b. Depressing the brake pedal. c. Pressing the "ON−OFF" button. If the preset speed is cancelled by pulling the lever or depressing the brake pedal, the "RADAR READY" appears on the multi−information display and the dynamic laser cruise control enters the ready mode. If the preset speed is cancelled by pressing the "ON−OFF" button, the "CRUISE" indicator light goes off in the instrument panel. In this case, the preset speed data is cleared, and you must set the speed from the beginning. In the following cases, the preset speed automatically cancels out: a. The vehicle speed falls below about 40 km/h (25 mph). (40 km/h (25 mph) is designated as a cancel speed.) b. The slip indicator light blinks and an alarm sounds. (This occurs when the vehicle is about to skid.) If cancelled by a. or b., a message "RADAR READY" appears on the multi−information display and the dynamic laser cruise control enters the ready mode. If a warning message appears on the multi−information display, the preset speed is automatically cancelled. See "(l) Vehicle−to−vehicle distance control mode failure warning" on page 436. 430
