When Driving

i-ACTIVSENSE



  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.



  The Mazda Radar Cruise Control (MRCC) warning light (amber) turns on when the 

system has a malfunction.

 Refer to Warning/Indicator Lights on page 4-20.

 Close Proximity Warning

If your vehicle rapidly closes in on the vehicle ahead because the vehicle applies the brakes 

suddenly while you are traveling 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.
