*Some models.
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 (front) to detect the distance to a vehicle
ahead, which frees the driver 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 suf¿ cient distance between the vehicles.
The possible vehicle speed setting ranges are as follows:
 


 (European models) 
 About 30 km/h (19 mph) to 200 km/h (124 mph)



 (Except European models) 
 About 30 km/h (19 mph) to 145 km/h (90 mph)
Use the Mazda Radar Cruise Control (MRCC) system on expressways and other highways
which do not require a lot of repeated acceleration and deceleration.

4–14 3
When Driving
i-ACTIVSENSE
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 speci¿ 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 suf¿ 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 safer distance from
vehicles ahead or on-coming vehicles.

Do not use the Mazda Radar Cruise Control (MRCC) system in the following locations.
Otherwise, it could lead to an accident:
 
 Roads with sharp curves and where vehicle traf¿ c is heavy and there is insuf¿ 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).
  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).
  Slippery roads such as ice or snow-bound roads (The tyres could spin causing you to
lose vehicle control).
  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.

 The clutch pedal is not depressed. 
 (Automatic transaxle) 



 The selector lever is in the drive (D) position or manual (M) position (manual
mode).
 
 In the following cases, the warnings may not activate even if your vehicle starts
closing in on the vehicle ahead.
 


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



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



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


 Another vehicle cuts into the driving lane. 

 The following are not detected as physical objects. 



 Vehicles approaching in the opposite direction



 Pedestrians



 Stationary objects (stopped vehicles, obstructions) 

 If a vehicle ahead is travelling at an extremely low speed, the system may not detect it
correctly.
  During headway control travel, do not set the system on two-wheeled vehicles such as
motorcycles and bicycles.
  Do not use the Mazda Radar Cruise Control (MRCC) system under conditions in
which the close proximity warnings are frequently activated.

4–14 5
When Driving
i-ACTIVSENSE
NOTE
  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 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.
  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 travelling at a constant speed and
following a vehicle ahead.
  The Mazda Radar Cruise Control (MRCC) warning light (amber) illuminates when the
system has a malfunction.
 Refer to Warning Lights on page 4-36 .   The headway control operation can be cancelled and the system can be switched to
only cruise control. Refer to Cruise Control Function on page 4-152 .

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.
  Headway control is not possible if the vehicle ahead is driving faster than the set
speed. 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.
