2020 MAZDA MODEL CX-9 lane assist

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.
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 notifies 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 by turnin g 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.

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
indicator light, the 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.

Lane-keep Assist System (LAS) & Lane Departure
Warning System (LDWS)
*
The LAS & LDWS alerts the driver that the vehicle may be deviating from its lane and it
provides steering assistance to help the driver stay within the vehicle lanes.
The Forward Sensing Camera (FSC) detects the white lines (yellow lines) of the vehicle
lane in which the vehicle is traveling and if the system determines that the vehicle may
deviate from its lane, it operates the electric power steering to assist the driver's steering
operation. The system also alerts the driver by activating a lane departure warning sound,
vibrating the steering wheel, and indicating an alert in the display. Use the system when you
drive the vehicle on roads with white (yello w) lines such as expressways and highways.
Refer to Forward Sensing Camera (FSC) on page 4-201.

WA R N I N G
Do not rely completely on the LAS & LDWS:
 The LAS & LDWS is not an automatic driving system. In addition, the system is not designed
to compensate for a driver's lack of caution, and over-reliance on the system could lead to
an accident.
 The detection ability of the LAS & LDWS is limited. Always stay on course using the steering
wheel and drive with care.
Do not use the LAS & LDWS in the following cases:
The system may not operate adequately accordin g to the actual driving conditions, resulting
in an accident.

If the indication on the active driving
display has been turned off using the
personalization features, the LAS & LDWS
indication on the multi-information
display is displayed in gray and the system
goes on standby.
The LAS & LDWS goes on stand-by
status in the following cases:
The system cannot detect white (yellow)
lane lines.
The vehicle speed is less than about 60
km/h (37 mph).
The ABS/TCS is operating.
The TCS is turned off.
(If the TCS is turned off while the
system is operational, a warning beep is
heard and the system goes on standby.)
The vehicle is making a sharp curve.
The brake pedal is depressed.
The steering wheel is operated abruptly.
The width of a lane is excessively
narrow or wide.
NOTE
The LAS & LDWS does not operate until
the system detects white (yellow) lane
lines on either the left or right.
When the system detects a white
(yellow) lane line on one side only, the
system will not operate the steering
wheel operation assist and the warning
for the lane line on the side that is not
being detected. The steering wheel
operation assist and the warning is only
for a lane deviation on the side that is
being detected.
If the driver takes his or her hands off
the steering wheel (not holding the
steering wheel), the warning sound is
activated and an alert is indicated in the
multi-information display or the active
driving display.

Active Driving Display Multi-information Display
If the steering wheel is held lightly, or
depending on the road conditions, the
system may detect that you have
released the steering wheel (not holding
the steering wheel) even if you are
holding it, and display a message in the
multi-information display or the active
driving display.

▼Lane Departure Warning
If the system determines that the vehicle ma
y deviate from its lane, the lane departure
warning (beep sound, rumble sound
*1, or steering wheel vibration) is activated and the
direction in which the system determines that the vehicle may deviate is indicated in the
multi-information display and the active driving display.
If the system determines that the vehicle may de viate from its lane, the color of the lane line
on the side being detected by the system changes from white to amber, and flashes.
Multi-information Display Active Driving Display
NOTE
If you have set the lane departure warning sound to the beep sound/rumble sound*1
setting, the warning sound may not be heard depending on the surrounding noise
conditions.
If you have set the lane departure warning system to the steering wheel vibrations setting,
the vibration may not be felt depending on the road surface conditions.
When the setting for the steering operation assist is changed to operational, the warnings
can be set to activate/not activate. (When the setting for the steering operation assist is
changed to non-operational, the warnings cannot be set to not activate.)
Refer to Setting Change (Personalization Features) on page 9-9.
The LAS & LDWS can be changed to the following settings regardless of whether the
steering operation assist has been set to operational/non-operational. Always check the
setting status when driving the vehicle and make setting changes if necessary.
Refer to Setting Change (Persona lization Features) on page 9-9.
Steering wheel vibration: Strong/weak
Warning sound volume
Types of warnings (steering wheel vibration/beep sound/rumble sound*1)
*1 A rumble strip is a series of grooves in the road pavement surface positioned at specific

Forward Sensing Camera (FSC)*
Your vehicle is equipped with a Forward Sensing Camera (FSC). The Forward Sensing
Camera (FSC) is positioned near the rearvi ew mirror and used by the following systems.
High Beam Control System (HBC)
Lane-keep Assist System (LAS) & Lane Departure Warning System (LDWS)
Traffic Sign Recognition System (TSR)
Advanced Smart City Brake Support (Advanced SCBS)
Smart City Brake Support (SCBS)
Mazda Radar Cruise Control with Stop & Go function (MRCC with Stop & Go function)
Smart Brake Support (SBS)
The Forward Sensing Camera (FSC) determines the conditions ahead of the vehicle while
traveling at night and detects traffic lanes. The distance in which the Forward Sensing
Camera (FSC) can detect objects varies depending on the surrounding conditions.
WA R N I N G
Do not modify the suspension:
If the vehicle height or inclination is changed, the system will not be able to correctly detect
vehicles ahead. This will result in the system not operating normally or mistakenly operating,
which could cause a serious accident.
CAUTION
 Do not apply accessories, stickers or film to the windshield near the Forward Sensing
Camera (FSC).
If the area in front of the Forward Sensing Came ra (FSC) lens is obstructed, it will cause the
system to not operate correctly. Consequently, each system may not operate normally
which could lead to an unexpected accident.
