Mazda Radar Cruise Control with Stop & Go function
(MRCC with Stop & Go function)
*
The MRCC with Stop & Go function system is designed to maintain headway control*1
with a vehicle ahead according to your vehicle's speed using a radar sensor (front) to detect
the distance to the vehicle ahead and a preset vehicle speed without you having to 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 such as if 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.
If the vehicle ahead stops while you are following behind it, your vehicle will stop and be
held stopped automatically (stop hold control), and headway control will resume when you
resume driving the vehicle such as by pressing the RES switch.
Also refer to the following before using the MRCC with Stop & Go function.
AUTOHOLD (page 4-59)
Forward Sensing Camera (FSC) (page 4-126)
Radar sensor (front) (page 4-131)
WA R N I N G
Do not rely completely on the MRCC with Stop & Go function:
The MRCC with Stop & Go function 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 dece lerate sufficiently to avoid hitting the vehicle
ahead if the vehicle ahead applies the brakes sudd enly or another vehicle cuts into the driving
lane, which could result in an accident.
Always drive carefully and verify the surroundi ng conditions and depress the brake pedal or
accelerator pedal while keeping a safer distance from vehicles ahead or on-coming vehicles.
Do not use the MRCC with Stop & Go function system in the following locations, using the
MRCC with Stop & Go function system at the following locations may result in an unexpected
accident:
 General roads other than high ways (Driving under these conditions using the MRCC with
Stop & Go function system is not possible.)
 Roads with sharp curves and where vehicle
traffic is heavy and there is
insufficient space
between vehicles.

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 with Stop & Go function system is in use, it does not cancel even if the
selector lever is operated and any intended engine braking does not occur. If deceleration
is required, lower the set speed 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 with Stop & Go function automatic braking is
operating, however, they may not turn on while the vehicle is on a downslope at the set
vehicle speed or traveling at a constant speed and following a vehicle ahead.
