▼Lane Departure Warning System
(LDWS)
The LDWS alerts the driver that the
vehicle may be deviating from its lane.
The system detects the white (yellow)
lines on the tra
ffic lane using the
forward sensing camera (FSC) and if it
determines that the vehicle might be
deviating from its lane, it notifies the
driver by the LDWS.
Refer to Forward Sensing Camera
(FSC) on page 4-203.
Use the LDWS when you drive the
vehicle on roads with white (yellow)
lines.

Blind Spot Monitoring(BSM)
*
▼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 notifying the driver of the
presence of vehicles approaching from
the rear in an adjacent lane.
BSM operation
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 noti
fies
the driver by turning on the BSM
warning indicator light and displaying
the vehicle detection screen.
If the turn signal lever is operated to
signal a turn in the direction in which
the BSM warning indicator light is
illuminated while the approaching
vehicle is detected, the BSM notifies
the driver of possible danger flashing
on the BSM warning indicator light,
and by activating the warning sound
and the warning screen indicator
display.
The detection area on this system
covers the driving lanes on both sides
of the vehicle and from the rear part of
the front doors to about 50 m (164 ft)
behind the vehicle.
1. Your vehicle
2. Detection areas
WARNING
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
indicator light, th e warning sound and
the warning screen indicator display
may not activate or they 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.The i-ACTIVSENSE warning
indication/warning light in the
instrument cluster is turned o ff.
The vehicle speed is about 10
km/h (6.3 mph) or faster.

Mazda3_8JM2-EA -20H_Edition1_new 2020-7-10 17:21:34

The BSM will not operate under the
following circumstances.
The vehicle speed falls below
about 10 km/h (6.3 mph) even
though the i-ACTIVSENSE warning
indication/warning light is turned
off.
The shift lever (manual
transmission)/selector lever
(automatic transmission) is shifted
to reverse (R) and the vehicle is
reversing.
The turning radius is small (making
a sharp turn, turning at
intersections).
In the following cases, the
i-ACTIVSENSE warning indication/
warning light turns on and operation
of the system is stopped. If the
i-ACTIVSENSE warning indication/
warning light remains illuminated,
have the vehicle inspected at an
Authorized Mazda Dealer as soon as
possible.
Some problem with the system
including the BSM warning
indicator lights is detected.
A large deviation in the installation
position of a rear side radar sensor
on the vehicle has occurred.
There is a large accumulation of
snow or ice on the rear bumper
near a rear side radar sensor.
Remove any snow, ice or mud on
the rear bumper.
Driving on snow-covered roads for
long periods.
The temperature near the rear side
radar sensor becomes extremely
hot due to driving for long periods
on slopes during the summer.
The battery voltage has decreased.Under the following conditions, the
rear side radar sensor cannot detect
target objects or it may be di fficult to
detect them.
The rear bumper around the rear
side radar sensor is deformed.
Radio wave interference from a
radar sensor equipped on a nearby
vehicle.
The approaching vehicle is any of
the following shapes.
a) The size of the vehicle body is
extremely small.
b) The vehicle height is extremely low or high.
c) A special type of vehicle with a complex shape.
A vehicle is in the detection area at
the rear in an adjacent driving lane
but it does not approach. The BSM
determines the condition based on
radar detection data.
A vehicle is traveling alongside
your vehicle at nearly the same
speed for an extended period of
time.
Vehicles approaching in the
opposite direction.
A vehicle in an adjacent driving
lane is attempting to pass your
vehicle.
A vehicle is in an adjacent lane on
a road with extremely wide driving
lanes. The detection area of the
rear side radar sensor is set at the
road width of expressways.
In the following case, the flashing of
the BSM warning indicator light, and
the activation of the warning sound
and the warning screen indicator
display may not occur or they may be
delayed.
A vehicle makes a lane change
from a driving lane two lanes over
to an adjacent lane.
Driving on steep slopes.Crossing the summit of a hill or
mountain pass.

height between your driving lane
and the adjacent lane.
Directly after the BSM system
becomes operable by changing the
setting.
If the road width is extremely
narrow, vehicles two lanes over may
be detected. The detection area of
the rear side radar sensor is set
according to the road width of
expressways.
The BSM warning indicator light may
turn on and the vehicle detection
screen may be displayed in the
display in reaction to stationary
objects (guardrails, tunnels,
sidewalls, and parked vehicles) on

fl ash or the warning beep may be
activated several times when making
a turn at a city intersection.
Tu r n off the BSM while pulling a
trailer or while an accessory such as a
bicycle carrier is installed to the rear
of the vehicle. Otherwise, the radar’s
radio waves will be blocked causing
the system to not operate normally.
In the following cases, it may be
diffi cult to view the
illumination/
fl ashing of the BSM warning
indicator lights equipped on the
door mirrors.
