1. Press the TJA switch.The TJA standby indication (white) turns on. In addition, the TJA display
indication is displayed on the multi-information display at the same time.
2. Adjust the vehicle speed to the desired setting using the accelerator pedal andpress the RES switch up (SET+) or down (SET-) to start headway control.
The set speed is indicated on the display. At the same time, the TJA standby
indication (white) changes to the TJA set indication (green).
3. The headway control is operable when all of the conditions for it to operate aremet, or the steering assist function is op erable when all of the conditions for it to
operate are met.
NOTE
If a vehicle ahead is detected while traveling at a constant speed, the
vehicle-ahead indication is displayed and headway control is performed.
Additionally, when a vehicle ahead is no longer detected, the vehicle-ahead
indication turns off and the system switches back to travel at constant speed.
Headway control is not possible if the vehicle ahead is driving faster than your

Lane-keep Assist System (LAS)
*
▼Lane-keep Assist System (LAS)
The LAS provides stee
ring assistance to
help the driver stay within the vehicle
lane if the vehicle might be deviating.
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 displaying an alert on the
multi-information display and the
active driving display. Use the system
when you drive the vehicle on roads
with white (yellow) lines such as
expressways and highways.
1. Forward sensing camera (FSC)
WARNING
Do not rely completely on the LAS:
 The LAS is not an automated 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.

visible because of dirt or paint
flaking.
White (yellow) lane lines are less
visible because of bad weather (rain,
fog, or snow).
The vehicle is driven on a temporary
lane or section with a closed lane
resulting from construction where
there might be multiple white
(yellow) lane lines, or they are
interrupted.
The camera picks up an obscure line,
such as a temporary line being used
for construction, or because of
shade, unmelted snow, or groovesfilled with water.
The surrounding brightness suddenly
changes such as when entering or
exiting a tunnel.
Back-light is reflected off the road
surface.
The road surface is wet and shiny
after rain, or there are puddles on
the road.
The width of a lane is excessively
narrow.
The vehicle is driven on roads with
tight curves.
Heavy luggage is loaded in the
luggage compartment or on the rear
seat causing the vehicle to tilt.

the road or a junction.
The shade of a guardrail parallel to a
white (yellow) lane line is cast on the
road.
The illumination of the headlights is
weakened because of dirt or the
optical axis is deviated at night.
The road is excessively uneven.The vehicle is shaken after hitting a
road bump.
A vehicle in front of your vehicle is
running near a white (yellow) lane
line making it less visible.
The windshield is dirty or foggy.Strong light is directed from the front
of the vehicle (such as sunlight, or
headlights (high-beam) of
on-coming vehicles).

Emergency Lane Keeping(ELK)
*
▼Emergency Lane Keeping (ELK)
The ELK is a system designed to assist
the driver’s steering wheel operation to
avoid danger.
The ELK consists of the Blind Spot
Assist function to prevent your vehicle
from colliding with vehicles on
adjacent lanes, and the Road Keep
Assist function to prevent your vehicle
from deviating from the road.
Refer to Blind Spot Assist on page
4-141.
Refer to Road Keep Assist on page
4-144.
▼
Blind Spot Assist*
The Blind Spot Assist
function assists
the driver in avoiding collisions with
vehicles in adjacent lanes (excluding
vehicles approaching in the opposite
direction).
The Blind Spot Assist function detects
white lines (yellow lines) on the vehicle
lane using the Forward Sensing Camera
(FSC) and detects vehicles on adjacent
lanes using the rear side radar sensors.
If there is a possibility of a collision
with a vehicle in an adjacent lane
when you try to change lanes or if you
may deviate from your lane, it assists
your steering wheel operation to keep
you in the driving lane.
When the steering wheel operation
assist operates, a warning sound and
warning indications on displays alert
the driver of the possibility of a
collision. Furthermore, if the possibility
of a collision increases, a warning
sound and display indications alert the
driver of the danger.
WARNING
Do not rely completely on the Blind
Spot Assist function and always drive
carefully:
 The Blind Spot Assist function has
limitations. Do not rely completely
on the system and always stay on
course using the steering wheel.
 The Blind Spot Assist function is not
an autonomous 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.
When Driving
i-ACTIVSENSE
*Some models.4-141
CX-50_8KB8-EA-22A_Edition2_new 2022-1-6 14:55:18

The detection area of the camera
and sensors is limited. If the steering
wheel operation assist is operated
without detecting a two-wheeled
vehicle near the detecting vehicle, it
could result in an accident.
Do not use the system under the
following conditions. Otherwise, it
may result in an accident:
The vehicle is driven on slippery
roads such as icy roads,
snow-covered roads, and unpaved
roads.
 Tires other than the specified size are
used, such as when tire chains or
temporary spare tires are used.
 The vehicle is towing a camping
trailer or boat trailer.
 The vehicle is driven on roads other
than expressways and highways.
 The rear bumper around a rear side
radar sensor is deformed.
Operation conditions
The Blind Spot Assist function becomes
operational when all of the following
conditions are met.
The vehicle speed is about 64 km/h
(40 mph) or faster.
The vehicle is driven on a straight
road or gentle curve.
The system detects white (yellow)
lane lines on both sides.
There is a vehicle on the rear sides.A Mazda genuine trailer hitch is not
being used.
NOTE
If a Mazda genuine trailer hitch is
used, the Blind Spot Assist is
automatically turned off.
The Blind Spot Assist function may
not operate normally when any of
the following conditions is met.
A condition under which the
Forward Sensing Camera (FSC)
cannot detect a target object is
met.
Refer to Forward Sensing Camera
(FSC) on page 4-189.
The visibility of vehicles in adjacent
lanes is poor.
A vehicle in an adjacent lane
rapidly approaches at a high
speed.
Vehicles in adjacent lanes have any
of the following shapes.
The vehicle size is very small.The vehicle height is extremely
low or high.
A special type of vehicle with a
complex shape.
The visibility of white lines (yellow
lines) is poor (due to paint flaking
or dirt, or being hidden by vehicles
ahead).
There are multiple white lines
(yellow lines) or they are
interrupted.
A misleading line on the road is
picked up (such as temporary line
for construction, shadow, lingering
snow, or grooves filled with water).
The width of the vehicle lane is
narrow or wide.
