Travel status Display
During travel at constant
speed
During travel under
headway control
NOTE
  If a vehicle ahead is detected while
travelling at a constant speed, the
vehicle-ahead indication is displayed
and headway control is performed.
Additionally, when a vehicle ahead is
no longer detected, the vehicle-ahead
indication turns off and the system
switches back to travel at constant
speed.
  If you are driving the vehicle at
a speed faster than the set speed,
headway control on the vehicle ahead
is not possible Adjust the system to
the desired vehicle speed using the
accelerator pedal.
 (European models) When switching to a passing lane and
operating the direction indicator, the
system provides more acceleration
automatically if it determines that
more acceleration is required. Drive
while being careful of the road ahead
because you could approach the
vehicle ahead too closely.

To accelerate using the accelerator
pedal
Depress the accelerator pedal and press
and release the SET
or SET switch at
the desired speed. If a switch cannot be
operated, the system returns to the set
speed when you release your foot from the
accelerator pedal.
CAUTION
The warnings and brake control do not
operate while the accelerator pedal is
depressed.
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 cancelled.
