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
 If your vehicle deviates from its traffic lane, the LDWS operates (warning sound and
indicator light). Steer the vehicle adequately to drive the vehicle to \
the center of the lane. 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.
 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.
 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.
 The LDWS does not operate if it does not detect the white or ye llow lines of the traffic
lane.

Blind Spot Monitoring (BSM) System
The Blind Spot Monitoring (BSM) system is designed to assist the driver in checking the
area to the rear of the vehicle on both sides during lane changes by ale\
rting the driver to the
presence of vehicles approaching from the rear in an adjacent lane.
The Blind Spot Monitoring (BSM) system 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 on the
Blind Spot Monitoring (BSM) warning lights equipped on the door mirrors depending on
the conditions. If the turn signal lever is operated to signal a lane ch\
ange in the direction
in which the Blind Spot Monitoring (BSM) warning light is illuminated, the system warns
the driver of a vehicle in the detection area by flashing the Blind Spot Monitoring (BSM)
warning light and activating a beep sound.
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 th\
e vehicle.
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
Blind Spot Monitoring (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 Blind Spot Monitoring (BSM) system will operate when all of the fo\
llowing
conditions are met:
 The ignition is switched ON. The Blind Spot Monitoring (BSM) switch is pressed and the Blind Spot Monitoring
(BSM) OFF indicator light in the instrument cluster is turned off. The vehicle speed is about 10 km/h (6.3 mph) or faster .

 The Blind Spot Monitoring (BSM) system will not operate under the foll\
owing
circumstances.
 The vehicle speed falls below about 10 km/h (6.3 mph) even though the \
Blind Spot
Monitoring (BSM) OFF indicator light is turned off. The shift lever (manual transaxle)/selector lever (automatic transaxl\
e) is shifted to
reverse (R) and the vehicle is reversing.
 In the following cases, the Blind Spot Monitoring (BSM) OFF indicator light flashes and
operation of the system is stopped. If the Blind Spot Monitoring (BSM)\
OFF indicator
light remains flashing, have the vehicle inspected at an Authorized Mazda Dealer as soon
as possible.
 Some problem with the system including the Blind Spot Monitoring (BSM) warnin\
g
lights is detected. 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). Remove any snow, ice or mud on the rear bumper. Driving on snow-covered roads for long periods. The temperature near the radar sensors (rear) becomes extremely hot due to driving
for long periods on slopes during the summer. The battery voltage has decr eased.
 Under the following conditions, the radar sensors (r ear) cannot detect target objects or it
may be difficult to detect them.
 A vehicle is in the detection area at the rear in an adjacent driving lane but it does not
approach. The Blind Spot Monitoring (BSM) system determines the condition \
based on
radar detection data.
 A vehicle is traveling alongside your vehicle at nearly the same speed fo\
r 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 radar sensors (rear) is set at the road width of expressways.
 In the following cases, the activation of the Blind Spot Monitoring (BS\
M) warning lights
and the warning beep 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. The turning radius is small (making a sharp turn, turning at intersecti\
ons). When there is a difference in the height between your driving lane and the adjacent
lane. Directly after pressing the Blind Spot Monitoring (BSM) switch and the system
becomes operable.

 If the road width is extremely narrow, vehicles two lanes over may be detected.
The detection area of the radar sensors (rear) is set according to the road width of
expressways.
 The Blind Spot Monitoring (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.
The walls at the entrance and exits of tunnels, turnouts.
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.

activated several times when making a turn at a city intersection. Turn off the Blind Spot Monitoring (BSM) system 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 difficult to view the illumination/flashing of the Blind
Spot Monitoring (BSM) warning lights equipped on the door mirrors.
 Snow or ice is adhering to the door mirrors. The front door glass is fogged or covered in snow, frost or dirt.
 The system switches to the Rear Cross Traffic Alert function when the shift lever (manual
