Rear Cross Traf¿ c Alert (RCTA) operation
1. The Rear Cross Traf¿ c Alert (RCTA) system operates when the shift lever (manual
transaxle) or the selector lever (automatic transaxle) 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 À ashes and the warning beep is activated
simultaneously.
(With rear view monitor)
The Rear Cross Traf¿ c Alert (RCTA) warning indication in the rearview monitor also
synchronizes with the Blind Spot Monitoring (BSM) warning indicator light on the door
mirrors.


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 À ash 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.

NOTE
  In the following cases, the Blind Spot Monitoring (BSM) warning indication/warning
light turns on and operation of the system is stopped. If the Blind Spot Monitoring
(BSM) warning indication/warning light remains illuminated, have the vehicle
inspected at an Authorised Mazda Dealer as soon as possible.
 


 Some problem with the system including the Blind Spot Monitoring (BSM) warning
indicator lights has occurred.
 


 A large deviation in the installation position of a radar sensor (rear) on the vehicle
has occurred.
 


 There is a large accumulation of snow or ice on the rear bumper near a radar sensor
(rear).
 


 Driving on snow-covered roads for long periods.



 The temperature near the radar sensors becomes extremely hot due to driving for
long periods on slopes during the summer.
 


 The battery voltage has decreased.

NOTE
  In the following cases, it may be dif¿ cult to view the illumination/À ashing of the Blind
Spot Monitoring (BSM) warning indicator lights equipped on the door mirrors.
 


 Snow or ice adheres to the door mirrors.



 The front door glass is fogged or covered in snow, frost or dirt. 

 Turn off the Rear Cross Traf¿ c Alert (RCTA) system while pulling a trailer or while
an accessory such as a bicycle carrier is installed to the rear of the vehicle. Otherwise,
the radio waves emitted by the radar will be blocked causing the system to not operate
normally.

When Driving
i-ACTIVSENSE
NOTE
  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, however, they may not be illuminated while the
vehicle is on a down slope at the set vehicle speed or travelling at a constant speed and
following a vehicle ahead.
  The Mazda Radar Cruise Control (MRCC) warning light (amber) illuminates when the
system has a malfunction.
 Refer to Warning Lights on page 4-36 .   The headway control operation can be cancelled and the system can be switched to
only cruise control. Refer to Cruise Control Function on page 4-152 .

NOTE
  In the following cases, the ultrasonic sensors (rear) cannot detect obstructions correctly
and the Smart City Brake Support [Reverse] (SCBS R) may not operate.
 


 Something is stuck on the bumper near an ultrasonic sensor (rear).



 The steering wheel is turned sharply, or the brake or accelerator pedal is operated.



 There is another obstruction near one obstruction.



 During inclement weather such as rain, fog and snow.



 High or low humidity.



 High or low temperatures



 Strong winds.



 The path of travel is not À at.



 Heavy luggage is loaded in the luggage compartment or on the rear seat.



 Objects such as a wireless aerial, fog light, or illuminated number plate is installed
near an ultrasonic sensor (rear).

collision.
 


 The vehicle is affected by other sound waves such as the horn, engine noise,
ultrasonic sensor of another vehicle.
 
 In the following cases, an ultrasonic sensor (rear) may detect something as a target
obstruction which could cause the Smart City Brake Support [Reverse] (SCBS R)
system to operate.
 


 Driving on a steep slope.



 Wheel blocks.



 Hanging curtains, gate poles such as at toll gates and railroad crossing.



 When travelling near objects such as foliage, barriers, vehicles, walls, and fences
along a road.

*Some models.
Forward Sensing Camera (FSC) *
Your vehicle is equipped with a Forward Sensing Camera (FSC). The Forward Sensing
Camera (FSC) is positioned near the rearview mirror and used by the following systems.
 


 High Beam Control System (HBC)



 Adaptive LED Headlights (ALH)



 Driver Attention Alert (DAA)



 Lane Departure Warning System (LDWS)



 Traf¿ c Sign Recognition System (TSR)



 Advanced Smart City Brake Support (Advanced SCBS)



 Smart City Brake Support [Forward] (SCBS F)



 Smart Brake Support (SBS)

Forward Sensing Camera (FSC)

The Forward Sensing Camera (FSC) determines the conditions ahead of the vehicle while
travelling at night and detects traf¿ c lanes. The distance in which the Forward Sensing
Camera (FSC) can detect objects varies depending on the surrounding conditions.
WARNING
Do not modify the suspension:
If the vehicle height or inclination is changed, the system will not be able to correctly
detect vehicles ahead. This will result in the system not operating normally or
mistakenly operating, which could cause a serious accident.
