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 an d 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 follo wing 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 usin g the MRCC with Stop & Go function.
AUTOHOLD (page 4-93)
Forward Sensing Camera (FSC) (page 4-201)
Radar sensor (front) (page 4-206)
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 weat her conditions, and the road conditions.
Additionally, the system may be unable to decelerate 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 surrounding 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 highways (Driving under these conditions using the MRCC with
Stop & Go function system is not possible.)
 Roads with sharp curves and where vehicle tr affic is heavy and there is insufficient space
between vehicles.

Smart Brake Support(SBS)
*
The SBS system alerts the driver of a
possible collision us ing a display and
warning sound if the radar sensor (front)
and the Forward Sensing Camera (FSC)
determine that there is the possibility of a
collision with a vehicle ahead while the
vehicle is being driven at about 15 km/h or
faster (10 mph or faster). Furthermore, if
the radar sensor (front) and the Forward
Sensing Camera (FSC) determines that a
collision is unavoidable, the automatic
brake control is performed to reduce
damage in the event of a collision.
In addition, when the driver depresses the
brake pedal, the brakes are applied firmly
and quickly to assist. (Brake Assist (SBS
brake assist))
WA R N I N G
Do not rely completely on the SBS system
and always drive carefully:
The SBS is designed to reduce damage in
the event of a collision, not avoid an
accident. The ability to detect an
obstruction is limited depending on the
obstruction, weather conditions, or traffic
conditions. Therefore, if the accelerator
pedal or brake pedal is mistakenly
operated it 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.
CAUTION
In the following cases, turn the system off
to prevent a mis-operation:
 The vehicle is being towed or when
towing another vehicle.
 The vehicle is on a chassis roller.
 When driving on rough roads such as in
areas of dense grass or off-road.
NOTE
The SBS system operates when all of the
following conditions are met:
The ignition is switched ON.
The SBS system is on.
The vehicle speed is about 15 km/h or
faster (10 mph or faster).
The relative speed between your
vehicle and the vehicle ahead is about
15 km/h or faster (10 mph or faster).
The Dynamic Stability Control (DSC)
is not operating.
The SBS system may not operate under
the following conditions:
If the vehicle is accelerated rapidly
and it comes close to a vehicle ahead.
The vehicle is driven at the same
speed as the vehicle ahead.
The accelerator pedal is depressed.
The brake pedal is depressed.
The steering wheel is being operated.
The selector lever is being operated.
The turn signal is being used.
When the vehicle ahead is not
equipped with taillights or the

checking the area surrounding the vehicle using various indications in the center display and
a warning sound while the vehicle is being driven at low speeds or while parking.
To p v i e w
The top view displays an image of the vehicl e from directly above on the center display
by combining the images taken from the 4 cameras set on all sides of the vehicle. The top
view displays on the right side of the screen when the front view or rear view screen is
being displayed. The top view assists the driver in checking the area surrounding the
vehicle when the vehicle is moving forward or in reverse.
Front view/front wide view
The image from the front of the vehi cle is displayed on the center display.
The view from the front assists the driver in checking the front of the vehicle by
displaying guide lines on the displayed image taken from the front of the vehicle.
Side view
The images taken from the front left and right sides of the vehicle are displayed on the
center display.
The side view assists the driver in checking the front sides of the vehicle by displaying
guide lines on the displayed image taken from the front left and right sides of the vehicle.
Rear view/rear wide view
The image from the rear of the vehicle is displayed on the center display.
The image from the rear assists the driver in checking the rear of the vehicle by displaying
guide lines on the displayed image taken from the rear of the vehicle.
Parking sensor
If there are any obstructions near the vehicle while the top view/side view is displayed, an
obstruction detection indication turns on around the bumper in the center display.
The parking sensors use ultrasonic sensors to detect obstructions around the vehicle when
the vehicle is driven at low speeds, such as during garage or parallel parking, and notifies
the driver of the approximate distance fro m the vehicle to the surrounding obstruction
using sound and an obstruction detection indication.
Refer to Parking Sensor System on page 4-229.
Rear Cross Traffic Alert (RCTA)
If there is the possibility of a collision with an approaching vehicle while the rear view/
rear wide view is displayed, a warning is displayed on the center display.
The Rear Cross Traffic Alert (RCTA) uses radar sensors (rear) to detect vehicles
approaching from the rear left and right sides of the vehicle, and it assists the driver in
checking the rear of the vehicle while reversing by flashing the Blind Spot Monitoring
(BSM) warning lights and activating the warning sound.
