Traffic Jam Assist (TJA)*
The TJA is a system which consists of a headway control function and a steering assist
function for reducing driver fatigue during traffic jams when driving on expressways or
highways.
This system performs headway control to maintain a constant distance between your vehicle
and a vehicle ahead at a preset vehicle speed without you having to use the accelerator or
brake pedal. Even further, with the steering assist function, when vehicle lane lines are
detected, the function assists the driver in k eeping the vehicle within the lane lines. If lane
lines are not detected, the function provides th e driver driving assistance in keeping the
vehicle along the motion path with the vehicle ahead.
WA R N I N G
Do not rely completely on TJA:
 The TJA is not an automated driving system. In addition, the functions have limitations. Do
not rely completely on the system and always stay on course using the steering wheel.
 Set a vehicle speed within the speed limit acco rding to the road conditions and the weather
conditions.
 The TJA may not be able to detect a vehicle ahead depending on the type of vehicle ahead
and its conditions, the weather conditions, and the road conditions. Add\
itionally, the
system might be unable to decelerate suffic iently if a vehicle ahead applies the brakes
suddenly, another vehicle cuts into the driving lane, or the difference in vehicle speed
between your vehicle and the vehicle ahead is larger, which could result in an accident.
Check the surrounding conditions and always drive carefully while keeping a safe distance
from vehicles ahead and on-coming vehicles.

For the purposes of safety, switch the TJA off when it is not being used.
Leaving the TJA turned on when it is not in us e is dangerous as it could operate unexpectedly,
resulting in an accident.

Do not use the TJA under the following conditions. Otherwise, it may result in an accident.
 General roads other than expressways or high ways (Driving under these conditions using
the TJA is not possible.)
 Roads with sharp curves and where vehicle tr affic is heavy with insufficient space between
vehicles, or roads where frequent and repet itive acceleration and deceleration occur
(Driving under these conditions using the TJA is not possible).

When entering and exiting interchanges, servic e areas, and parking areas of expressways (If
you exit an expressway while headway control is in use, the vehicle ahead will no longer be
tracked and your vehicle may a ccelerate to the set speed).
 Slippery roads such as icy or snow-covered roads and unpaved roads (Tires could spin
causing you to lose vehicle control, or the stop hold control may not operate.)
 Long, descending slopes (to maintain distance between vehicles, the system automatically
and continuously applies the brakes which could result in the loss of brake power.)
 Two-wheeled vehicles such as mo torcycles or bicycles are ahead.
 Slopes with a steep gradient (The vehicle ahea d may not be detected correctly, your vehicle
may slip while stopped by the stop hold control, or it may accelerate suddenly after it starts
moving.)
 Driving under bad weather conditions (rain, fog, and snow).
 Tires of a
different
specified size are used, such as a temporary spare tire.
 Tires with insufficient tread are used.
 The tire pressures are not adjusted to the
specified pressure.
 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.

Do not get out of the vehicle while the stop hold control is operating.
Getting out of the vehicle while the stop hold co ntrol is operating is dangerous as the vehicle
may move unexpectedly and result in an accident . Before getting out of the vehicle, switch the
TJA off, apply the parking brake, and then sh ift the selector lever to the P position.

CAUTION
Heed the following cautions so th at the TJA can operate normally.
 Turn the system off when the vehicle is running on a chassis roller.
 Do not modify the vehicle's suspensions.
 Always use wheels of the specified size for th e front and rear wheels. Consult an Authorized
Mazda Dealer for tire replacement.

NOTE
The headway control does not detect the following as physical objects.
Vehicles approaching in the opposite direction

Pedestrians
Stationary objects (stopped vehicles, obstructions)
If a vehicle ahead is traveling at an extremely low speed, the system may not detect it
correctly.
If there is a structure on the road or an object (such as a monorail) at a low height off the
ground in front of the vehicle, the system may operate. Therefore, do not use the TJA.
Do not use the TJA under conditions in which close proximity warnings are frequently
activated.
If it is necessary to accelerate for a lane change or the vehicle ahead brakes suddenly
causing you to close in on the vehicle rapidly, accelerate using the accelerator pedal or
decelerate using the brake pedal depending on the conditions.
While the TJA is in use, any intended engine braking does not occur even if you shift the
selector lever. If deceleration is required, lower the vehicle speed setting or depress the
brake pedal.
While braking by the TJA control is operating, you might hear an operation sound,
however, this does not indicate a problem.
The brake lights turn on while braking by the TJA control is operating, however, they may
not turn on while the vehicle is on a down slope at the set vehicle speed or traveling at a
constant speed and following a vehicle ahead.
Under the following conditions, the TJA may no t be able to detect white (yellow) lines or
vehicles ahead correctly and the TJA may not operate normally.
The forward sensing camera (FSC) cannot recognize the area in front of the vehicle due
to soiling or fog.
The white (yellow) lane lines are less vi sible because of dirt or paint flaking.
White (yellow) lane lines or vehicles ahe ad 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 grooves filled with water.
The road surface is wet and shiny after rain, or there are puddles on the road.
Heavy luggage is loaded in the luggage compartment or on the rear seat causing the
vehicle to tilt.
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.
The vehicle is driven through an intersection, a junction, or a fork in the road.
While white (yellow) lane lines cannot be detected due to road or weather conditions.
The surrounding brightness suddenly changes such as when entering or exiting a
tunnel.

Advanced Smart City Brake Support (Advanced SCBS)*
The Advanced SCBS alerts the driver of a possible collision using the display and a warning
sound when the Forward Sensing Camera (FSC) detects a vehicle ahead or pedestrian and
determines that a collision with the object is unavoidable while the vehicle is driven at a
vehicle speed of about 4 to 80 km/h (2 to 50 m ph) if the object is a vehicle ahead and about
10 to 80 km/h (6.2 to 50 mph) if the object is a pedestrian. In addition, the system reduces
damage in the event of a collision by operating the brake control (Advanced SCBS brake)
when the system determines that a collision is unavoidable. In addition, when the driver
depresses the brake pedal, the brakes are appl ied firmly and quickly to assist. (Brake Assist

Smart City Brake Support [Forward] (SCBS F)*
The SCBS F system alerts the driver of a possible collision using an indication in the
display and a warning sound when the Forward Sensing Camera (FSC) detects a vehicle
ahead and determines that a collision with a vehicle ahead is unavoidable while the vehicle
is being driven at a vehicle speed of about 4 to 80 km/h (2 to 50 mph). In addition, the
system reduces damage in the event of a collis ion by operating the brake control (Smart City
Brake Support (SCBS) brake) when the system determines that a collision is unavoidable
while the vehicle is being driven at a vehicle speed of about 4 to 30 km/h (2 to 18 mph). It
may also be possible to avoid a collision if the relative speed between your vehicle and the
vehicle in front of you is less than about 20 km/h (12 mph). In addition, when the driver
depresses the brake pedal while the system is in the operation range at about 4 to 30 km/h (2
to 18 mph), the brakes are applied firmly and quickly to assist. (Brake Assist (Smart City
Brake Support (SCBS) brake assist))
