STARTING AND DRIVING
170
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.
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.
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 lowered 1.6
km/h (1 mph) each time by pressing the control lever downward in
the ”SET/COAST” direction quickly within 0.6 seconds.
However, a quicker way to reset is to depress the brake pedal and
then press the control lever downward in the ”SET/COAST”
direction.
Even if you downshift the transmission from the ”D” position to ”4”
with the cruise control on, engine braking will not be applied because
the cruise control 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.
Resuming the preset speed
If the preset speed is cancelled by pulling the control lever or by
depressing the brake pedal, pushing the lever up in the ”RES/ACC”
direction will restore the speed set prior to cancellation. However,
once the vehicle speed falls below about 40 km/h (25 mph), the
preset speed will not be resumed.
