▼LDWS Warning
If the system determines that there is the
possibility of a lane
departure, the LDWS
warning beep activates and the LDWS
warning light flashes. Operate the steering
wheel appropriately and steer the vehicle
to the center of the lane.
For vehicles equipped with the
multi-information display, the color of the
lane line in the direction which the system
determined that the vehicle may be
deviating from its lane changes from white
to amber and the vehicle lane line flashes.

NOTE
If the LDWS warning sound is set to
rumble
*1, the sound will be heard from
the vehicle speaker on the side which the
system determined the vehicle may be
deviating from its lane.
It may be difficult to hear the LDWS
warning beep depending on the
surrounding conditions such as outside
noise.
The volume of the LDWS warning sound
can be changed.
Refer to Personalization Features on
page 9-9.
The type of warning sound (rumble*1/
beep) on the LDWS can be changed.
Refer to Personalization Features on

*1 A rumble strip is a series of grooves in the road pavement surface positioned
at specific intervals, and when the
vehicle passes over it a vibration and
rumble sound is produced which alerts
the driver that the vehicle is departing
from the lane.
The rumble sound is a reproduction of
the sound which occurs when a vehicle
passes over a rumble strip.

Blind Spot Monitoring (BSM)*
The BSM is designed to assist the driver in checking the area to the rear of the vehicle on
both sides during lane changes by alerting the driver to the pr esence of vehicles approaching
from the rear in an adjacent lane.
The BSM detects vehicles approaching from the rear while traveling in the forward
direction at a speed of 10 km/h (6.3 mph) or faster and turns o n the BSM warning lights
equipped on the door mirrors depending on the conditions. If th e turn signal lever is
operated to signal a lane change in the direction in which the BSM warning light is
illuminated, the system warns the driver of a vehicle in the de tection area by flashing the
BSM warning light and activating a beep sound.
The detection area on this system covers the driving lanes on b oth sides of the vehicle and
from the rear part of the doors to about 50 m (164 ft) behind t he vehicle.
Detection areas Your vehicle
WA R N I N G
Always check the surrounding area visually before making an actual lane change:
The system is only designed to assist you in checking for vehicles at your rear when making a
lane change. Due to certain limitations with the operation of this system, the BSM warning
light may not flash or it might be delayed even though a vehicle is in an adjacent driving lane.
Always make it your responsibility as a driver to check the rear.
NOTE
The BSM will operate when all of the following conditions are met:
The ignition is switched ON.

detection area of the radar sensors (rear) is set according to the road width of
expressways.
The BSM warning lights may turn on in reaction to stationary objects on the road or the
roadside such as guardrails, tunnels, sidewalls, and parked vehicles.
Objects such as guardrails and concrete walls
running alongside the vehicle.Places where the width between guardrails or
walls on each side of the vehicle narrows.

BSM warning lights
The BSM warning lights are equipped on the left and right door mirrors. The warning lights
turn on when a vehicle approaching from the rear in an adjacent lane is detected.
When the ignition is switched ON, the malfunction warning light turns on momentarily and
then turns off after a few seconds.
Forward driving (BSM system operation)
The BSM system detects vehicles approaching from the rear and t urns on the BSM warning
lights equipped on the door mirro rs according to the conditions. Additionally, while a BSM
warning light is illum inated, if the turn signal lever is operated to signal a turn in the
direction in which the BSM warning light is illuminated, the BS M warning light flashes.
Reverse driving (Rear Cross Traf fic Alert (RCTA) system operation)
The Rear Cross Traffic Alert (RCTA) system detects vehicles app roaching from the left and
right of your vehicle and flashes the BSM warning lights.
Function for cancelling illumination dimmer
If the BSM warning lights turn on when the parking lights are t urned on, the brightness of
the BSM warning lights is dimmed.
If the BSM warning lights are difficult to see due to glare fro m surrounding brightness when
traveling on snow-covered roads or under foggy conditions, pres s the dimmer cancellation
button to cancel the dimmer and increase the brightness of BSM warning lights when they
turn on.

Traffic Sign Recognition System (TSR)*
The TSR helps prevent the driver from overlooking traffic signs, and provides support for
safer driving by displaying traf fic signs on the multi-information display which are
recognized by the Forward Sensing Camera (FSC) or recorded in t he navigation system
while the vehicle is driven.
The TSR displays the speed limit, do not enter, and traffic sto p signs.
If the vehicle speed exceeds the speed limit sign indicated in the multi-information display
while the vehicle is driven, the system notifies the driver using the indication in the
multi-information display and a warning sound.
NOTE
The TSR is not supported in some countries or regions. For information concerning the
supported countries or regions, consult an Authorized Mazda Dealer.
The TSR operates only if the navigation syst em SD card (Mazda genuine) is inserted in
the SD card slot. Consult an Authorized Mazda Dealer for details.

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 alertin g 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.
