STARTING AND DRIVING
3. 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.
However, a quicker way to reset is to accelerate the
vehicle and then press the control lever downward in the
"SET/COAST" direction.

4. 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.
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 turn off the overdrive switch 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.
5. 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.
