WARNING
Do not rely completely on DAA and
always drive carefully:
The DAA detects driver fatigue and
decreased attentiveness and
encourages the driver to take a rest,
however, it is not designed to prevent
the vehicle from straying. If you rely too
much on the DAA it could lead to an
accident. Drive carefully and operate
the steering wheel appropriately.
In addition, the system may not be
able to detect driver fatigue and
decreased attentiveness correctly
depending on the traffic and driving
conditions. The driver must take
suffi cient rest in order to drive safely.
NOTE
The DAA operates when all of the
following conditions are met.
The vehicle speed is about 65 to
140 km/h (41 to 86 mph).
The system detects white (yellow)
lane lines.
The system has completed learning
of the driver’s driving data after 60
minutes have passed since the
driver began driving vehicle.
The DAA does not operate under the
following conditions.
The vehicle speed is less than
about 65 km/h (41 mph).
The vehicle speed exceeds about
140 km/h (86 mph).
The vehicle is making a sharp turn.The vehicle is changing lanes.The system cannot detect white
(yellow) lane lines.
The DAA may not operate normally
under the following conditions.
White (yellow) lane lines are less
visible because of dirt or fading/
patchiness.
The vehicle is jolted or swayed
continuously by strong winds or
rough roads.
The vehicle is driven aggressively.When making frequent lane
changes.
The vehicle is making a curve.The DAA detects driver fatigue and
decreased attentiveness based on
the driving data when the vehicle is
driven at about 65 to 140 km/h (41
to 86 mph) for about 20 minutes.
The driving data will be reset under
the following conditions.
The vehicle is stopped for 15
minutes or longer.
The vehicle is driven at less than
about 65 km/h (41 mph) for
about 30 minutes.
The power switch is switched
off.After the DAA has displayed the first
message encouraging rest, it does
not display the next one until 60
minutes have passed.

WARNING
Do not rely completely on the DM
and always drive carefully:
The DM is a system which detects
driver fatigue and sleepiness, and
encourages the driver to take a rest.
This is not designed to prevent driver
fatigue and sleepiness, and
over-reliance on the system could lead
to an accident. Drive carefully and turn
the steering wheel appropriately.
In addition, the system may not be
able to detect driver fatigue and
sleepiness correctly depending on the
traffic and driving conditions. The
driver must take sufficient rest in order
to drive safely.
Operation conditions
The DM begins monitoring after 20
minutes have passed since the driver
began driving the vehicle and when
the vehicle speed is about 5 km/h (3
mph) or faster.
NOTE
If the vehicle speed decreases to less
than about 5 km/h (3 mph) while
the DM is monitoring , the DM stops
monitoring for 6 mi nutes even if the
vehicle speed returns to about 5
km/h (3 mph) or faster.
If the driver monitoring camera does
not recognize the driver correctly, the
DM may not monitor correctly.
Refer to Driver Monitoring Camera
on page 4-81.
After the DM has displayed the first
message encouraging the driver to
take a rest, it does not display it
again during the following periods.
After displaying the warning
pattern (caution), the next warning
pattern (caution) is not displayed
until 45 minutes have passed.
After displaying the warning
pattern (warning), the next
warning pattern (warning) is not
displayed until 15 minutes have
passed.
After displaying the warning
pattern (warning), the next
warning pattern (caution) is not
displayed until 45 minutes have
passed.

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.
A two-wheeled vehicle such as a
motorcycle or bicycle is traveling
ahead.
The vehicle is being towed.
Proximity warnings activate
frequently.

control using the Tra
ffic Jam Assist
(TJA), a warning sound is activated and
a brake warning is indicated on the
multi-information display. Check the
surrounding conditions and keep a
safe distance from the vehicle ahead.

CAUTION
While the accelerator pedal is being
depressed, the warnings and brake
control do not operate even if your
vehicle approaches the vehicle
ahead.
In the following cases, the warnings
and brakes may not operate even if
your vehicle approaches the vehicle
ahead.
Your vehicle is being driven at the

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.
