When Driving
Mazda Radar Cruise Control (MRCC)
NOTE
When accelerating using the SET
switch while in headway control, the set
vehicle speed can be adjusted but
acceleration is not possible. If there is
no longer a vehicle ahead, acceleration
continues until reaching the set vehicle
speed. Check the set vehicle speed by
viewing the set vehicle speed display in
the active driving display.
When depressing the accelerator pedal,
the inter-vehicle distance display in
the display in the instrument cluster
changes to the white-line display.
The minimum settable speed is 30 km/h
(19 mph). If the set vehicle speed
reaches 30 km/h (19 mph) using the
switch operation, constant speed travel
is maintained at about 30 km/h (19
mph) even if the SET switch is
pressed. The Mazda Radar Cruise
Control (MRCC) system is not
canceled.
