Mazda Radar Cruise Control (MRCC)
The Mazda Radar Cruise Control (MRCC) system is designed to maintain headway control *1
according to the vehicle speed using a radar sensor to detect the distance to a vehicle ahead,
and by presetting the vehicle speed between 30 km/h (19 mph) and 145 km/h (90 mph) the
driver is freed from having to constantly use the accelerator or brake pedals.
*1 Headway Control: Control of the distance between your vehicle and the vehicle ahead
detected by the Mazda Radar Cruise Control (MRCC) system.
Additionally, if your vehicle starts closing in on the vehicle ahead because, for example, the
vehicle ahead brakes suddenly, a warning sound and a warning indication in the display are
activated simultaneously to alert you to maintain a suffi cient distance between the vehicles.
Use the Mazda Radar Cruise Control (MRCC) system on expressways and other highways
which do not require a lot of repeated acceleration and deceleration.
WARNING
Do not rely completely on the Mazda Radar Cruise Control (MRCC) system and always
drive carefully:
The Mazda Radar Cruise Control (MRCC) system is designed to reduce load on the
driver, and although it maintains a constant vehicle speed, or specifi cally, it maintains
a constant distance between your vehicle and the detected vehicle ahead according to
the vehicle speed, the system has detection limitations depending on the type of vehicle
ahead and its conditions, the weather conditions, and the road conditions. Additionally,
the system may be unable to decelerate suffi ciently to avoid hitting the vehicle ahead
if the vehicle ahead applies the brakes suddenly or another vehicle cuts into the driving
lane, which could result in an accident. Always verify the safety of the surrounding area
and depress the brake pedal or accelerator pedal while keeping a safe distance from
vehicles ahead or on-coming vehicles.

When Driving
Mazda Radar Cruise Control (MRCC)
Do not use the Mazda Radar Cruise Control (MRCC) system in the following locations.
Otherwise, it could lead to an accident:
 


¾ Roads with sharp curves and where vehicle traffi c is heavy and there is insuffi cient
space between vehicles. Roads where frequent and repetitive acceleration and
deceleration occur (Driving under these conditions using the Mazda Radar Cruise
Control (MRCC) system is not possible).
 


¾ When entering and exiting interchanges, service areas, and parking areas of highways
(If you exit a highway while headway control is in use, the vehicle ahead will no longer
be tracked and your vehicle may accelerate to the set speed).
 


¾ Slippery roads such as ice or snow-bound roads (The tires could spin causing you to
lose vehicle control).
 


¾ 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).

For the purposes of safety, switch the Mazda Radar Cruise Control (MRCC) system off
when it is not being used.
CAUTION
If the vehicle is towed or you are towing something, switch the Mazda Radar Cruise
Control (MRCC) system off to prevent an incorrect operation.
NOTE




y The Mazda Radar Cruise Control (MRCC) system operates when all of the following
conditions are met.
 


y The vehicle speed is about 30 km/h (19 mph) to 145 km/h (90 mph).



y The Mazda Radar Cruise Control (MRCC) system is turned on.



y The parking brake is not applied.



y The Forward Obstruction Warning (FOW) indicator light (amber) does not illuminate.



y The Dynamic Stability Control (DSC) is operating normally.

(Manual transaxle)




y The shift lever is in a position other than reverse (R) or neutral (N).



y The clutch pedal is not depressed.

(Automatic transaxle)




y The selector lever is in the drive (D) position or manual (M) position (manual mode).

When Driving
Mazda Radar Cruise Control (MRCC)
 


y In the following cases, the warnings may not activate even if your vehicle starts closing
in on the vehicle ahead.
 


y You are driving at the same speed as the vehicle ahead.



y Directly after the Mazda Radar Cruise Control (MRCC) system has been set.



y When the accelerator pedal is depressed or directly after the accelerator pedal is
released.
 


y Another vehicle cuts into the driving lane.




y The following are not detected as physical objects.




y Vehicles approaching in the opposite direction



y Pedestrians



y Stationary objects (stopped vehicles, obstructions)




y If a vehicle ahead is traveling at an extremely low speed, the system may not detect it
correctly.
 


y During headway control travel, do not set the system on two-wheeled vehicles such as
motorcycles and bicycles.
 


y Do not use the Mazda Radar Cruise Control (MRCC) system under conditions in which
the close proximity warnings are frequently activated.
 


y 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.
 


y While the Mazda Radar Cruise Control (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.
 


y The brake lights are illuminated while the Mazda Radar Cruise Control (MRCC)
automatic braking is operating, however, they may not be illuminated while the vehicle is
on a down slope at the set vehicle speed or traveling at a constant speed and following a
vehicle ahead.
 


y The Mazda Radar Cruise Control (MRCC) warning light (amber) fl ashes when the
system has a malfunction.

How to Set the Distance Between
Vehicles During Headway Control
The distance between vehicles is set to a
shorter distance each time the
switch is
pressed. The distance between vehicles is
set to a longer distance by pressing the
switch. The distance-between-vehicles can
be set to 4 levels; Long, medium, short,
and extremely short distance.
Distance-between-
vehicles guideline
(at 80 km/h (50 mph)
vehicle speed) Indication on display
Long (about 50 m (164
ft))
Medium (about 40 m
(131 ft))
Short (about 30 m (98
ft))
Extremely short (about
25 m (82 ft))
NOTE
 


y The distance between vehicles differs
depending on the vehicle speed, and the
slower the vehicle speed, the shorter the
distance.
 


y 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.
Changing the Set Vehicle Speed
Changing the set vehicle speed using the
SET
/ SET switch
Press the SET
switch to accelerate. Press
the SET
switch to decelerate. The set
vehicle speed changes as follows each
time the SET
/ SET switch is pressed.
Short press 1 km/h (1 mph)
Long press 10 km/h (5 mph)
NOTE
For example, the set vehicle speed is
changed by pressing the SET
/ SET
switch four times as follows:
The vehicle speed accelerates or
decelerates by 4 km/h (4 mph).
To accelerate using 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.
