When the TJA switch is pressed while the TJA is operating, the TJA turns o ff.
▼ Stop Hold Control
While in headway control using the
Tra
ffic Jam Assist (TJA), your vehicle will
stop when a vehicle ahead stops.
When the vehicle is stopped and the
stop hold control operates, the TJA
indicator light turns on.
NOTE
The parking brake is automatically
applied and the vehicle is held in its
stopped position when 10 minutes or
longer have passed since the stop hold
control operated. When this occurs,
the TJA is temporarily canceled.
Resuming driving
While in stop hold control, if the
vehicle ahead starts moving and the
distance from the vehicle increases, the
stop hold control will be canceled and
your vehicle will resume driving by
performing any of the following
operations.

Lane-keep Assist System(LAS)
*
▼Lane-keep Assist System (LAS)
The LAS provides steering 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.
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.
The functions of the LAS have
limitations. Always stay on course
using the steering wheel and drive
with care.
Do not use the LAS under the
following circumstances, otherwise it
may result in an accident.
The vehicle is driven on slippery
roads such as icy or snow-covered
roads, and unpaved roads.
Tires of a
different
speci fied size
are used, such as a temporary
spare tire.
The vehicle is being used to tow a
camper or boat trailer.
Tire chains are used.
The vehicle is driven on roads with
lane lines other than white (yellow)
lines, such as an expressway.
NOTE
The system may not operate normally
under the following conditions.
A condition under which the forward
sensing camera (FSC) cannot detect
a target object is met.
Refer to Forward Sensing Camera
(FSC) on page 4-71.
The visibility of white (yellow) lines is
poor (due to paint flaking or dirt, or
being hidden by vehicles ahead).
There are multiple white (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 a lane is excessively
narrow.
The vehicle is shaken after hitting a
road bump.
The vehicle is driven on a section
with a closed lane or temporary lane
due to construction.

▼System Operation
Operation conditions
The Lane-keep Assist System (LAS)
becomes operational when all of the
following conditions are met.
The vehicle speed is about 64 km/h
(40 mph) or faster.
The system detects white (yellow)
lane lines.
NOTE
When the system does not detect a
white (yellow) lane line on one side
only, the system does not operate on
the side that is not being detected.
When temporarily canceling the
system
The LAS goes on stand-by when any of
the following condit
ions is met. The
LAS is automatically restored when its
operation conditions are met.
The system cannot detect white
(yellow) lane lines.
The vehicle speed is less than about
56 km/h (35 mph).
The turn signal lever is operated.The accelerator pedal is depressed
abruptly.
The TCS/DSC is operating.The TCS is turned off.The steering wheel is operated.The brake pedal is operated.
The function is temporarily stopped.
The LAS stops functioning in the
following cases:
The temperature in the forward
sensing camera (FSC) is too high or
too low.
The windshield around the forward
sensing camera (FSC) is foggy.
The windshield around the forward
sensing camera (FSC) is blocked by
an obstruction, causing poor forward
visibility.
Strong light (such as sunlight, or
headlights (high-beam) of
on-coming vehicles) is directed at
the forward sensing camera (FSC).
▼ Steering Wheel Operation Assist
When the system determines that the
vehicle might be deviating from its
lane, the steering wheel operation
assist operates.

using [Settings] in Mazda Connect, the
LAS is not automatically enabled.
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
4-129.
Refer to Road Keep Assist on page
4-133.
▼
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.
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 speci fied 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.

alert the driver of the possibility of a
road departure. Furthermore, if the
possibility of a road departure
increases, a warning sound and display
indications alert the driver of the
