SET+/
SET- SET+ If the switch is pressed upward when the vehicle speed exceeds 24km/h
{15 mph} with the system in stand-by, the vehicle speed at the point when
the switch is pressed upward is stored in the PCM and the system initiates
the cruise control.
The PCM controls acceleration by the pressing of the switch upward (tap-up
operation) or when the switch is continuously pressed upward during cruise
control.
SET- If the switch is pressed downward when the vehicle speed exceeds 24km/h
{15 mph} with the system in stand-by, the vehicle speed at the point when
the switch is pressed downward is stored in the PCM and the system
initiates the cruise control.
The PCM controls deceleration by the pressing of the switch downward
(tap-down operation) or when the switch is continuously pressed downward
during cruise control.
RESUME RESUME If the switch is pressed when the vehicle speed exceeds 24km/h {15 mph}
with the system in stand-by and the previous pre-set vehicle speed stored
in the PCM, the system initiates the cruise control so that the vehicle speed
is the pre-set vehicle speed stored in the PCM.
CANCEL CANCEL If the CANCEL switch is pressed during cruise control, the cruise control
system goes into stand-by (Pre-set vehicle speed is stored).
Btake switch Depressing the brake pedal during cruise control switches the cruise control system to
standby status.
