Distance Recognition Support System (DRSS)*
The DRSS measures the distance between your vehicle and a vehicle ahead using a radar
sensor (front) while the vehicle speed is ab out 30 km/h (19 mph) or faster, and if your
vehicle approaches a vehicle ahead more closely than what is appropriate for maintaining
distance between the vehicles according to the vehicle speed, a notification in the active
driving display is indicated to advise you to keep a safe distance from the vehicle ahead.
WARNING
Do not rely completely on the DRSS and always drive carefully:
The ability to detect a vehicle ahead is limited depending on th e type of vehicle ahead, the
weather conditions, and the traffic conditions. Therefore, if the accelerator and brake pedals
are not operated correctly it could lead to 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.
NOTE
The DRSS operates when all of the following conditions are met:
The ignition is switched ON.
The DRSS is on.
The selector lever is in a position other than reverse (R).
The vehicle speed is 30 km/h or faster (19 mph or faster).
The objects which activate the system are 4-wheeled vehicles.
The DRSS may also operate in the presence of motorcycles and bicycles.
The DRSS may not operate normally under the following conditions:
The Dynamic Stability Control (DSC) has a malfunction.
The vehicle ahead is traveling at an extremely slow speed.
The system does not operate with the following objects:
Vehicles approaching in the opposite direction.
Stationary objects (stopped vehicles, obstructions)
▼Indication on Display
The DRSS operation status is indicated in
the active driving display. Regarding
malfunctions, check the vehicle conditions or have it inspected by an Authorized Mazda
Dealer according to the content of the displayed message.

Rear Cross Traffic Alert (RCTA)*
The RCTA system is designed to assist the driver in checking the area to the rear of the
vehicle on both sides while the vehicle is reversing by alerting the driver to the presence of
vehicles approaching the rear of the vehicle.
The RCTA system detects vehicles approaching from the rear left and right sides of the
vehicle, and the rear of the vehicle while the 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.
Detection areas
Your vehicle
RCTA operation
1. The 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 poss ibility of a collision with an approaching vehicle, the Blind Spot
Monitoring (BSM) warning indicator lights fl ashes and the warning beep is activated
simultaneously.

The RCTA warning indication in the rearview monitor also synchronizes with the Blind
Spot Monitoring (BSM) warning indicator light on the door mirrors.
WA R N I N G
Always check the surrounding area visually before actually putting the vehicle in reverse:
The system is only designed to assist you in ch ecking for vehicles at the rear when putting the
vehicle in reverse. Due to certain limitations wi th 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.
NOTE
In the following cases, the Blind Spot Monitoring (BSM) OFF Indicator Light turns on
and operation of the system is stopped. If the Blind Spot Monitoring (BSM) OFF Indicator
Light remains illuminated, have the vehicle inspected at an Authorized 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.

may be difficult to detect them.
The vehicle speed when reversing is about 10 km/h (6.3 mph) or faster.
The radar sensor (rear) detection area is obstructed by a nearby wall or parked vehicle.
(Reverse the vehicle to a position where the radar sensor detection area is no longer
obstructed.)

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 RCTA system while pulling a trailer or while an accessory such as a bicycle
carrier is installed to the rear of the vehic le. Otherwise, the radio waves emitted by the
radar will be blocked causing the system to not operate normally.

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.

NOTE
The distance-between-vehicles differs depending on the vehicle speed, and the slower the
vehicle speed, the shorter the distance.
When the ignition is switched to ACC or OFF and then the engine is started again, the
system automatically sets the distance-between-vehicles to the previous setting.
How to change the set vehicle speed
To accelerate/decelerate using the SET
switch
When you press the SET
switch, the
vehicle accelerates and when you press the
SET
switch, it decelerates.
Short press 1 km/h (1 mph)
Long press 10 km/h (5 mph)
NOTE
For example, the set vehicle speed is
changed by pressing the SET switch four
times as follows:
The vehicle speed accelerates or
decelerates by 4 km/h (4 mph).
To increase speed using accelerator
