Tra ffi c Ja m A s s i s t ( TJ A )*
▼Tra ffi c
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 keeping the vehicle within the lane
lines. If lane lines are not detected, the
function provides the driver driving
assistance in keeping the vehicle along
the motion path with the vehicle
ahead.
WARNING
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 according to the road
conditions and the weather
conditions.

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.
(Automatic transmission vehicle)
Getting out of the vehicle while the
stop hold control 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 shift the selector lever
to the P position.

CAUTION
Turn the system off when the vehicle is
running on a chassis roller.
Heed the following cautions so that
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 the 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
Pe de st ri a ns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 shift lever (manual
transmission) or th e selector lever
(automatic transmission). 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 not 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
