Summary of Contents for Lexus LS430

Page 1 TABLE OF CONTENTS Dynamic Radar Cruise Control ............Dynamic Laser Cruise Control .
Page 2 Dynamic Radar Cruise Control DYNAMIC RADAR CRUISE CONTROL The millimeter wave radar sensor in this system primarily detects the reflected wave from the rear end of the vehicle ahead of you to deter- mine the presence of the vehicle ahead as well as measuring the vehicle–to–vehicle distance. The detection range of the sensor is about 120 m (400 ft.) ahead.
Page 3 J Operation Requirements Cruising from about 45 km/h (28 mph) to about 135 km/h (85 mph) The wipers are not operating at all or operating at low speed and operating intermittently (including the same wiper operation in the “AUTO” position). The driving pattern selector switch is set in the power or normal position.
Page 4 Dynamic Radar Cruise Control J Cautions F Do not rely too much on dynamic radar cruise control. Vehicle–to–vehicle distance control has its limitations. Always remain aware of the distance from the vehicle ahead and other vehicles. If necessary, depress the brake pedal to ensure sufficient distance.
Page 5 J Cautions F If other vehicles are driving outside of the millimeter wave radar detection range, a delay in the detection of the vehicle cutting in at short range or detection failure of the motorcycle running on the side of the same lane will occur. In this case, the dy- namic radar cruise control system will not function properly.
Page 6 Dynamic Radar Cruise Control J Warning Display If there is trouble somewhere in the dynamic radar cruise control while the vehicle–to–vehicle distance control mode is on, the “CRUISE” indicator light in the instrument cluster flashes, the master warning light comes on and the warning tone sounds, and one or more of the warning messages will appear on the multi–information display.
Page 7 J Operation Procedure The operation procedure is shown as follows. For the detailed information, see Section 3–1 in the “Owner’s Manual”. F Setting Push the “ON–OFF” button to turn on the system. The “CRUISE” indicator light in the instrument cluster comes on and “RADAR READY”...
Page 8 Dynamic Radar Cruise Control J Operation Procedure F Acceleration/Deceleration To accelerate: Depress the accelerator pedal. (When you release the accelerator pedal, follow–up cruising or fixed speed cruising resumes.) If there was no vehicle ahead, the vehicle will accelerate gradually to the preset speed. At this time, depressing the acceler- ator pedal will accelerate quickly.
Page 9 J Operation Procedure F To restore the previous control If the preset speed has been cancelled, when you press the lever upward in the “+RES” direction while “RADAR READY” shows up on the multi–information display and at a vehicle speed of about more than 40 km/h (25 mph), the speed set prior to cancellation will be restored.
Page 10 Dynamic Radar Cruise Control In addition to the vehicle–to–vehicle distance control mode described in this quick reference guide, dynamic radar cruise con- trol has conventional (fixed speed) cruise control mode for cruising at fixed speeds. For the conventional (fixed speed) cruise control mode, see Section 3–1 in the “Owner’s Manual”.
Page 11 DYNAMIC LASER CRUISE CONTROL The laser radar sensor in this system primarily detects the reflectors of the vehicle ahead of you to determine the presence of the vehicle ahead as well as measuring the vehicle–to–vehicle distance. The detection range of the sensor is about 120 m (400 ft.) ahead. F If no vehicle is detected ahead of you: D Your cruising speed is maintained at the preset speed from about 45 km/h (28 mph) to about 135 km/h (85 mph).
