Traffic Jam Assist (TJA)
The TJA is a system designed to reduce
driver fatigue during traffic jams when
driving on expressways or highways.
The TJA consists of a headway control
function and a steering assist function.
Headway control function
The function performs headway
control to maintain a constant distance
between your vehicle and a vehicle
ahead at a preset vehicle speed
without you having to depress the
accelerator or brake pedal.
Steering assist function
When vehicle lane lines are detected,
the function assists your steering
operation to follow the vehicle lane
lines.
When vehicle lane lines are not
detected, the function assists your
steering operation to follow the
trajectory of the vehicle ahead.
Also refer to the following information
before using the TJA.

Refer to Forward Sensing Camera
(FSC) on page 4-71.

Refer to Front Radar Sensor on page
4-77.
WARNING
Do not rely completely on the TJA and
always drive carefully:

The TJA is not an automated driving
system. Therefore, the function has
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 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. Additionally, the system
might be unable to decelerate
sufficiently if the vehicle ahead
applies the brakes suddenly or
another vehicle cuts into your lane,
which 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 roads other
than expressways and highways.

The vehicle is driven on roads with
sharp curves or with heavy traffic
where sufficient distances between
vehicles cannot be kept.

The vehicle is driven on roads where
acceleration and deceleration are
frequently repeated.

The vehicle is exiting the main lane
on an expressway to enter an
interchange, a rest area, or a parking
area.

The vehicle is driven on slippery
roads such as icy roads,
snow-covered roads, and unpaved
roads.

The vehicle is driven on a long
downslope.

The vehicle is driven on a steep
slope.

A two-wheeled vehicle such as a
motorcycle or bicycle is traveling
ahead.

The vehicle is being towed.

Proximity warnings activate
frequently.
