Resetting To A Faster Speed (Dynamic Radar/Laser Cruise Control); Resetting To A Slower Speed (Dynamic Radar/Laser Cruise Control) - Lexus 2004 LS430 Owner's Manual

3 Resetting to a faster speed
Press the control lever upward in the "RES/ACC" direction and
hold it. The displayed speed will increase in increments of 5
mph (for U.S.A.) or 5 km/h (for Canada). Release the lever
when the desired speed is attained. The vehicle will gradually
increase to the displayed speed.
Depressing the accelerator pedal and pressing the control
lever downward in the "SET/COAST" direction will not reset to
a faster speed. At this time the set speed falls by 5 mph (for
U.S.A.) or 5 km/h (for Canada).
STARTING AND DRIVING
4 Resetting to a slower speed
Press the control lever downward in the "SET/COAST"
direction and hold it. The displayed speed will decrease in
increments of 5 mph (for U.S.A.) or 5 km/h (for Canada).
Release the lever when the desired speed is attained. The
vehicle will gradually decrease to the displayed speed.
A quicker way to reset the preset speed is to depress the brake
pedal and then press the control lever downward in the
"SET/COAST" direction.
If the control lever is released when the vehicle speed exceeds
the upper limit of the preset speed traveling downhill while you
are pressing the control lever downward, the system will
memorize the upper limit of the preset speed as a preset
speed.
Even if you downshift the transmission from "D" or "6" (sixth
range) to "5" (fifth range), or from "D" or "5" (fifth range) to "4"
(fourth range) in the vehicle-to-vehicle distance control mode,
engine braking will not be enabled because this mode is not
cancelled. To decrease the vehicle speed, reset to a slower
speed with the cruise control lever or depress the brake pedal.
If you use the brake pedal, cruise control is cancelled.
