Rear Cross Traffic Alert
(RCTA)
*
▼Rear Cross Traffic Alert (RCTA)
The RCTA system is designed to assist
the driver in checking the area to the
rear left and right sides of your vehicle
while your vehicle is reversing by
alerting the driver to the presence of
vehicles approaching the rear of your
vehicle.
The RCTA system detects vehicles
approaching from the rear left and
right sides of your vehicle and the rear
of your vehicle while your vehicle is
being reversed out of a parking space,
and notifies the driver of possible
danger using the Blind Spot Monitoring
(BSM) warning indicator lights and the
warning buzzer.

WARNING
Always check the surrounding area
visually before actually putting the
vehicle in reverse:
The system is only designed to assist
you in checking for vehicles at the rear
when putting the vehicle in reverse.
Due to certain limitations with the
operation of this system, the Blind Spot
Monitoring (BSM) warning indicator
lights may not flash or it might be
delayed even though a vehicle is
behind your vehicle. Always make it
your responsibility as a driver to check
the rear.
RCTA operation
1. The RCTA system operates when the shift lever (manual
transmission) or the selector lever
(automatic transmission) is shifted
to the reverse (R) position.
2. If there is the possibility of a collision with an approaching
vehicle, the Blind Spot Monitoring
(BSM) warning indicator lights
flashes and the warning beep is
activated simultaneously.
Rear view monitor (vehicles with
Rear view monitor)
The RCTA warning indication in the
rearview monitor also synchronizes
with the Blind Spot Monitoring
(BSM) warning indicator light on
the door mirrors.
360°view monitor (vehicles with
360°view monitor)
The RCTA warning indication in the
360°view monitor also
synchronizes with the Blind Spot
Monitoring (BSM) warning
indicator light on the door mirrors.
Function for canceling illumination
dimmer
If the BSM warning indicator lights turn
on when the parking lights are turned
on, the brightness of the BSM warning
indicator lights is dimmed.
If the BSM warning indicator lights are
difficult to see due to glare from
surrounding brightness when traveling
on snow-covered roads or under foggy
conditions, press the dimmer
cancellation button to cancel the
dimmer and increase the brightness of
BSM warning indicator lights when
they turn on.
Refer to Dashboard Illumination on
page 4-17.
NOTE
The system may operate under the
following conditions even if a vehicle
is not approaching.

Mazda Radar Cruise
Control (MRCC) (Manual
Transmission)
*
▼Mazda Radar Cruise Control
(MRCC)
The MRCC system is designed to
maintain headway control*1 with a
vehicle ahead according to your
vehicle's speed using a front radar
sensor 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
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.
Also refer to the following before using
the MRCC.

CX-30_8HG6-EA-19I_Edition1_new 2019-6-13 18:45:11

WARNING
Do not rely completely on the MRCC:
The MRCC 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
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.
Always drive carefully and verify the
surrounding conditions and depress
the brake pedal or accelerator pedal
while keeping a safe distance from
vehicles ahead or on-coming vehicles.
Do not use the MRCC system in the
following locations. Using the MRCC
system at the following locations may
result in an unexpected accident:
General roads other than highways
(Driving under these conditions
using the MRCC system is not
possible.)
 Roads with sharp curves and where
vehicle traffic is heavy with
insufficient space between vehicles,
or roads where frequent and
repetitive acceleration and
deceleration occur (Driving under
these conditions using the MRCC 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 (Tires could spin
causing you to lose vehicle control,
or the stop hold control may not
operate.)
 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.)
 Slopes with a steep gradient (The
vehicle ahead may not be detected
correctly.)
 Two-wheeled vehicles such as
motorcycles or bicycles are ahead.
For safety purposes, switch the MRCC
system off when it is not being used.
Leaving the MRCC system turned on
when it is not in use is dangerous as it
could operate unexpectedly, resulting
in an accident.
CAUTION
 Turn the system
off when the vehicle
is running on a chassis roller.
 If your vehicle is towed or you are
towing something, switch the MRCC
system off to prevent an unexpected
operation.
NOTE
The MRCC system does not detect
the following as physical objects.
Vehicles approaching in the
opposite direction
Pe de st r ia nsStationary objects (stopped
vehicles, obstructions)
If a vehicle ahead is traveling at an
extremely low speed, the system
may not detect it correctly.
When Driving
i-ACTIVSENSE
4-115
CX-30_8HG6-EA-19I_Edition1_new 2019-6-13 18:45:11

If there is a structure on the road or
an object (such as a monorail) at a
low height off the ground in front of
the vehicle, the system may operate.
Therefore, do not use the MRCC.
Do not use the MRCC system under
conditions in which close proximity
warnings are frequently activated.
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 system is in use, it
does not cancel even if the shift lever
is operated and any intended engine
braking will not occur. If deceleration
is required, lower the vehicle speed
setting or depress the brake pedal.
While braking by the MRCC control
is operating, you might hear an
operation sound, however, this does
not indicate a problem.
The brake lights turn on while
braking by the MRCC control is
operating, however, they may not
turn on while the vehicle is on a
down slope at the set vehicle speed
or traveling at a constant speed and
following a vehicle ahead.
Stop the headway control function to
switch the system to the cruise
control function.
Refer to the Settings section in the
Mazda Connect Owner's Manual.
