2005 Lexus LS 430 Owners Manual - Page 352

STARTING AND DRIVING Vehicles with the cruise control - When the cruise control is being used, even if you downshift from "D" or "5" (fifth range) to "4" (fourth range), engine braking will not be enabled because the cruise control is not cancelled. For vehicle speed reduction, see page 329. Vehicles with the dynamic radar/laser cruise control - When the cruise control is being used in the conventional (fixed speed) cruise control mode or in the vehicle−to−vehicle distance control mode, even if you downshift from "D" or "5" (fifth range) to "4" (fourth range), engine braking will not be enabled because the cruise control is not cancelled. For vehicle speed reduction, see pages 360 and 345. D Shift into the "3" (third range) position. The transmission will downshift to third gear when the vehicle speed is or becomes lower than 146 km/h (91 mph) and more powerful engine braking will be enabled. If you drive in the "D" position: Shift the selector lever to the "S" position and shift the lever down to the "-" position twice to select the "3" (third range). However, when you move the lever to the "S" position while the AI shifting control is operating, the first shift range will be "5" (fifth range), "4" (fourth range) or "3" (third range) because the suitable shift range is selected depending on the driving condition. If you drive in the "S" position: Shift the selector lever down to the "-" position to select "3" (third range). D Shift into the "2" (second range) position. The transmission will downshift to second gear when the vehicle speed is or becomes lower than 98 km/h (61 mph) and more powerful engine braking than that of the "3" (third range) position will be enabled. If you drive in the "D" position: Shift the selector lever to the "S" position and shift the lever down to the "-" position three times to select "2" (second range). If you drive in the "S" position: Shift the selector lever down to the "-" position to select "2" (second range). D Shift into the "1" (first range) position. The transmission will downshift to first gear when the vehicle speed is or becomes lower than 35 km/h (22 mph) and maximum engine braking will be enabled. If you drive in the "D" position: Shift the selector lever to the "S" position and shift the lever down to the "-" position four times to select "1" (first range). If you drive in the "S" position: Shift the selector lever down to the "-" position to select "1" (first range). CAUTION Be careful when downshifting on a slippery surface. The abrupt change in engine speed could cause the vehicle to skid or spin. 313
