STARTING AND DRIVING

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.
With the cruise control on, even if you downshift the
transmission from the "D" position or "6" (sixth range) to the "5"
(fifth range), or from the "D" position or "5" (fifth range) to the
"4" (fourth range), engine braking will not be enabled 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, by
depressing the brake pedal or vehicle stability control
activation, 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.
