Traffic Jam Assist (TJA)*
▼ Tra
ffic 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 fo llowing 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
suffi ciently 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 tra ffic
where su fficient 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.

▼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

▼Smart Brake Support (SBS)
The SBS is a system designed to detect
target objects using sensors and
cameras equipped on the vehicle, and
to reduce damage in the event of a
collision by operating the brake control
if there is the possibi
lity of your vehicle
colliding with a target object.
One part of the SBS functions when
you are driving forward and the other
part functions when you are driving in
reverse.
Refer to Forward drive detection on
page 4-136.
Refer to Reverse drive detection on
page 4-138.
▼ Forward drive detection
When you are driving forward, the
following functions of the Smart Brake
Support (SBS) operate.
Forward detection function
WARNING
Do not rely completely on the
SBS:
The SBS is only designed to reduce
damage in the event of a collision.
The system may not operate normally
depending on the target object,
weather conditions, or tra ffic
conditions. Over reliance on the
system leading to the accelerator pedal
or brake pedal being mistakenly
operated could result in an accident.
CAUTION
In the following cases, turn the SBS o ff
to prevent a mis-operation.
 The vehicle is being towed.
 The vehicle is driven on rough roads
such as in areas where there is grass
and foliage or o ff-road.

Support (SBS) System Operation on
page 4-143.
Forward detection function
The forward detection function is
designed to reduce damage in the
event of a collision with target objects
at the front.
The forward detection function detects
target objects (vehicles ahead,
pedestrians, and bicycles) using the
front radar sensor and the Forward
Sensing Camera (FSC). If there is a
possibility of your vehicle colliding with
a target object at the front, you are
noti fied of possible danger by a
warning sound and a warning
indication on the display.
Furthermore, if the possibility of a
collision increases, the brake control is
performed to reduce damage in the
event of a collision. In addition, when
the driver depresses the brake pedal,
the brakes are applied firmly and
quickly to assist.
