4Resetting to a slower speed
Press the control lever downward in the - SETº 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 - SETº 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 - SETº
direction.
Even if you downshift the transmission from the Dº position to
4º position 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.
5Resuming 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 +
RESº 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.
