When Driving
Blind Spot Monitoring (BSM) System
Blind Spot Monitoring (BSM) System *
The Blind Spot Monitoring (BSM) system is designed to assist the drive\
r by monitoring
blind spots on both sides of the vehicle to the rear in certain situatio\
ns such as when
changing lanes on roads and freeways or reversing the vehicle from a par\
king garage.
The Blind Spot Monitoring (BSM) System consists of the Blind Spot Moni\
toring (BSM)
and Rear Cross Traffi c Alert (RCTA).
WARNING
Do not rely completely on the Blind Spot Monitoring (BSM) system. Always look over
your shoulder before changing lanes or reversing the vehicle from a parking garage:
The Blind Spot Monitoring (BSM) system can assist the driver in confi rming the safety of
the surroundings but is not a complete substitute. The driver is responsible for assuring
lane changes and other maneuvers. Always pay attention to the direction in which the
vehicle is traveling and the vehicle's surroundings.
NOTE
 y The detectability of the radar sensors has its limitations. The Blind Sp\
ot Monitoring
(BSM) System may not operate properly under the following conditions:
 y Ice, snow, or soil adheres to the rear bumper surface around the radar sensors. y During adverse weather conditions such as rain or snow, or under conditions where
water is sprayed.
 y The rear bumper area around the radar sensors is blocked by foreign material (such as
stickers or a bicycle carrier).
 y The radar sensors do not detect human, animal, shopping cart, bicycle, o\
r static objects
such as fences.
 y The radar sensors may not detect all types of vehicles around your vehicle, especially the
following types of vehicles:
 y Motorcycles y Vehicles with body shapes that radar may not refl ect such as a fl atbed trailer with no
cargo.
 y Vehicles with lower body height such as sports cars.
 y Although the system may detect objects on the road side such as parked vehicles or
guardrails and operate the warning light/beep, it does not indicate a malfun\
ction.
 y If the vehicle is driven on a road with less traffi c and few vehicles that the radar sensors
can detect, the system may pause (the Blind Spot Monitoring (BSM) OFF\
indicator light
in the instrument cluster fl ashes). However, it does not indicate a malfunction.

When Driving
Blind Spot Monitoring (BSM) System
 y The following conditions may affect the visibility of the Blind Spot Mon\
itoring (BSM)
warning lights on the outside mirror, making it diffi cult to confi rm the illumination of the
lights:
 y Ice or snow adheres to the surface of the outside mirrors. y The door window glass is tinted.
 y The radar sensors are equipped inside the rear bumper (page 4-114 ). y Have the radar sensors inspected at an Authorized Mazda Dealer if any shock is applied
to the rear bumper, even in a minor accident. If the vehicle is driven with a damaged
radar sensor, the system may not operate properly resulting in an accident.
 y For repairs or paintwork around the radar sensors, or replacement of the bumper, consult
an Authorized Mazda Dealer.
 y The radar sensors of the Blind Spot Monitoring (BSM) system may be regulated under
the radio wave related laws of the country where the vehicle is driven. The sensors in this
system are approved for use in the U.S.A. (including territories), Canada, and Mexico\
.
If a vehicle with a Blind Spot Monitoring (BSM) system is driven in a \
country other
than the U.S.A., Canada, or Mexico, the system has to be turned off usin\
g the Blind Spot
Monitoring (BSM) OFF switch.
Blind Spot Monitoring (BSM)
The Blind Spot Monitoring (BSM) system monitors the detection areas on\
both sides of
the vehicle to the rear and when there are vehicles in the detection are\
a it notifi es the driver
by illuminating the Blind Spot Monitoring (BSM) warning light while th\
e vehicle speed is
about 10 km/h (6.2 mph) or faster and driving forward.
If the turn signal lever is operated to the side the Blind Spot Monitori\
ng (BSM) warning
light is illuminated, the Blind Spot Monitoring (BSM) warning light fl\
ashes and the system
warns the driver of the vehicle in the detection area using a BSM warnin\
g beep sound.

When Driving
Blind Spot Monitoring (BSM) System
NOTE
 y The Blind Spot Monitoring (BSM) does not operate when the vehicle spee\
d is lower than
about 10 km/h (6.2 mph).
 y The detection area of the Blind Spot Monitoring (BSM) has been determined based on
the lane width of general freeways. Therefore on a road with a narrower lane width, the
system may detect vehicles on a lane next to the adjacent lane and opera\
te the warning
light/beep. On a road with wider lane width, the system may not detect vehicles on the
adjacent lane and may not operate the warning light/beep.
 y Under the following conditions, the system may be unable to detect vehic\
les, or detection
may be delayed.
 y The vehicle accelerates from a standing-start with a vehicle alongside. y A vehicle moves from a lane two lanes over to the adjacent lane. y The difference in vehicle speed between your vehicle and another vehicle is larger
when passing or being passed, and the vehicle passes the detection area within a short
period of time.
 y On a steep incline, or when there is a difference in height between lanes. y Immediately after the system has been activated by pressing the Blind Spot Monitoring
(BSM) OFF switch again after it has been turned off (Blind Spot Monit\
oring (BSM)
OFF indicator light in instrument cluster illuminates) by pressing the switch.
 y (Automatic transaxle vehicles) The shift lever is shifted to the R position, or directly after being shifted from the R
position.
 y The system may not operate normally when towing a trailer. Turn off the system by
operating the Blind Spot Monitoring (BSM) OFF switch when towing a tra\
iler.
 y The system switches to the Rear Cross Traffi c Alert function when the shift lever (Manual
transaxle) or the selector lever (Automatic transaxle) is shifted to \
the R position.

Lane Departure Warning System (LDWS)
Lane Departure Warning System (LDWS) *
The LDWS notifi es the driver that the vehicle may be deviating from its lane.
The system detects the white or yellow lines on the traffi c lane using the Forward Sensing
Camera (FSC). If it determines that the vehicle may be deviating from \
its lane, it notifi es
the driver by fl ashing the LDWS indicator light (green) and operating the LDWS warning\

sound.
Refer to Forward Sensing Camera on page 4-62 .
Use the LDWS when you drive the vehicle on roads with white or yellow li\
nes.

When Driving
Lane Departure Warning System (LDWS)
CAUTION
Do not modify the suspension. If the vehicle height or the damping force of the
suspensions is changed, the LDWS may not operate correctly.
NOTE
 y If your vehicle deviates from its traffi c lane, the LDWS operates (warning sound and
indicator light). Steer the vehicle adequately to drive the vehicle to \
the center of the lane.
 y When the turn signal lever is operated for a lane change, the LDWS warni\
ng is
automatically canceled. The LDWS warning becomes operable when the turn \
signal lever
is returned and the system detects the white or yellow lines.
 y If the steering wheel, accelerator pedal, or brake pedal is operated abr\
uptly and the
vehicle moves close to a white or yellow line, the system determines tha\
t the driver is
making a lane change and the LDWS warning is automatically canceled.
 y The LDWS may not operate during the period immediately after the vehicle\
has deviated
from its lane and the LDWS has operated, or the vehicle deviates from its lane repeatedly
within a short period of time.
 y The LDWS does not operate if it does not detect the white or yellow line\
s of the traffi c
lane.
