Mazda Radar Cruise Control (MRCC) system
The Mazda Radar Cruise Control (MRCC) system is designed to maintain 
headway control according to the vehicle speed using a radar sensor to detect the 
distance to a vehicle ahead, which frees the driver from having to use the 
accelerator or brake pedals.
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 
sufficient 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. The possible vehicle speed setting ranges are as follows:
Do not rely completely on the Mazda Radar Cruise Control (MRCC) system 
and always drive carefully:
The Mazda Radar Cruise Control (MRCC) system has limitations in its ability to 
detect vehicles ahead depending on the weather and road conditions.
Additionally, the system may be unable to decelerate sufficiently 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. 
Check the safety of the surroundings and pay sufficient attention to the 
distance between your vehicle and the vehicles travelling in front and behind.
WARNING
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, heavy traffic, or roads requiring repeated and 
frequent acceleration.
• When entering expressway interchanges and service areas.
• Slippery roads such as ice or snow-bound roads.
• Long descending slopes.
• (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)

Setting the Mazda Radar Cruise Control (MRCC)
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.

Change the Set Vehicle Speed
Changing the set vehicle speed using the SET + / SET - switch
Press and hold the SET + or SET - switch to adjust the set vehicle speed in 10 km/h 
(5 mph) increments.
The set vehicle speed can also be adjusted in 1 km/h (1 mph) (European models) 
or 5 km/h (5 mph) (Except European models) increments by pressing and 
releasing the SET + or SET - switch immediately.
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.
Close Proximity Warning
If your vehicle rapidly closes in on the vehicle ahead 
because the vehicle applies the brakes suddenly while you 
are travelling in headway control, the warning sound 
activates and the brake warning is indicated in the display.
Always verify the safety of the surrounding area and 
depress the brake pedal while keeping a safer distance from 
the vehicle ahead. Additionally, always keep a safer 
distance from the vehicles behind you.
