Long, descending slopes (to maintain distance between vehicles, the system automatically
and continuously applies the brakes which could result in the loss of brake power.)
Slopes with a steep gradient (The vehicle ahea d may not be detected correctly, your vehicle
may slide while stopped by the stop hold control, and it may accelerate suddenly after it
starts moving.)
For safety purposes, switch the MRCC system off when it is not being used.
CAUTION
If your vehicle is towed or you are towing some thing, switch the MRCC system off to prevent a
miss-operation.
NOTE
•The MRCC system does not detect the following as physical objects.
•Vehicles approaching in the opposite direction
•Pedestrians
•Stationary objects (stopped vehicles, obstructions)
•If a vehicle ahead is travelling at an extre mely low speed, the system may not detect it
correctly.
•During headway control travel, do not set the system for detection of two-wheeled
vehicles such as motorcycles and bicycles.
•Do not use the MRCC system under conditions in which close proximity warnings are
frequently activated.
•During headway control travel, the system accelerates and decelerates your vehicle in
conjunction with the speed of the vehicle ahead. However, if it is necessary to accelerate
for a lane change or if the vehicle ahead brakes suddenly causing you to close in on the
vehicle rapidly, accelerate using the accelerator pedal or decelerate using the brake
pedal depending on the conditions.
•While the MRCC system is in use, it does not cancel even if the selector lever (automatic
transaxle)/shift lever (manual transaxle) is operated and any intended engine braking will
not occur. If deceleration is required, lower the vehicle speed setting or depress the brake
pedal.
•The sound of the automatic brakes operating may be heard, however, it does not indicate
a problem.
•The brake lights turn on while the MRCC automatic braking is operating, however, they
may not turn on while the vehicle is on a downslope at the set vehicle speed or travelling
at a constant speed and following a vehicle ahead.

If there is a problem with the MRCC system, a message is displayed on the
multi-information disp lay. Check the centre display to verify the problem and then have
your vehicle inspected by an expert repairer, we recommend an A uthorised Mazda Repairer.
Refer to Message Indicated on Display on page 7-61.
▼ Close Proximity Warning
If your vehicle rapidly closes in
on the vehicle ahead because the vehicle ahead applies the
brakes suddenly while you are travelling in headway control, th e warning sound activates
and the brake warning is indicated in the display. Always verif y the safety of the
surrounding area and depress the brake pedal while keeping a sa fer distance from the
vehicle ahead. Additionally, keep a safer distance from the veh icles behind you.

•Directly after the MRCC system has been set.
•Directly after the accelerator pedal is released.
•Another vehicle cuts into the driving lane.
▼Setting the System
The MRCC system operates when all of the following conditions a
re met.
•The vehicle speed is as follows:
•(European models)
About 30 km/h (19 mph) to 200 km/h (124 mph)

How to set the distance-between-vehicles during headway control
The distance-between-vehicles is set to a shorter distance by pressing the switch. The
distance-between-vehicles is set to a longer distance by pressi ng the
switch. The
distance-between-vehicles can be set to 4 levels; Long, medium, short, and extremely short
distance.

NOTE
•The distance-between-vehicles differs depending on the vehicle speed, and the slower the
vehicle speed, the shorter the distance.
•When the ignition is switched to ACC or OFF and then the engine is started again, the
system automatically sets the distance-between-vehicles to the previous setting.

How to change the set vehicle speed
To accelerate/decelerate using the SET
switch
When you press the SET
switch, the
vehicle accelerates and when you press the
SET
switch, it decelerates.
European
models Except Euro-
pean models
Short press 1 km/h (1 mph) 5 km/h (5 mph)
Long press 10 km/h (5 mph)
NOTE
For example, the set vehicle speed is
changed by pressing the SET switch four
times as follows:
(European models)
The vehicle speed accelerates or
decelerates by 4 km/h (4 mph).
(Except European models)
The vehicle speed accelerates or
decelerates by 20 km/h (20 mph).
To increase speed using accelerator
pedal
Depress the accelerator pedal and press
and release the SET
switch or SET
switch at the desired speed. If the switch is
not operated, the system returns to the set
speed after 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. For the set vehicle speed, check
the set vehicle speed indication in the
display.
•When depressing the accelerator pedal,
the inter-vehicle distance indication in
the display changes to the white-line
indication.
•(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.
Cancelling the system
When the following operations are
performed, the MRCC system is
cancelled, and the MRCC set indication
(green) switches to the MRCC main
indication (white) at the same time.
•The OFF/CAN switch is pressed.
•The brake pedal is depressed.
•The electric parkin g brake (EPB) is
applied.
•(Automatic transaxle)
The selector lever i s in the P (Park), N
(Neutral), or R (R everse) position.
•(Manual transaxle)
The shift lever is in the reverse (R)
position.
•Any of the doors is opened.
