i-ACTIVSENSE*
▼i-ACTIVSENSE
i-ACTIVSENSE is a collective term
covering a series of advanced safety and
driver support systems which make use of
cameras and sensors. T
he systems consist
of active safety and pre-crash safety
systems.
These systems are designed to assist the
driver in safer driving by reducing the load
on the driver and helping to avert
collisions or reduce their severity.
However, because each system has its
limitations, always dri ve carefully and do
not rely solely on the systems.
▼ Active Safety Technology
Active Safety Technology supports safer
driving by helping the driver to recognize
potential hazards and avert accidents.

Traffic Sign Recognition System (TSR)*
▼Traffic Sign Recognition System (TSR)
The TSR helps prevent the driver
from overlooking traffic signs, and provides support for
safer driving by displaying traffic signs on the active driving display/instrument cluster
which are recognized by the Forward Sensing Camera (FSC) or rec orded in the navigation
system while the v ehicle is driven.
The TSR displays the speed limit (including auxiliary signs), do not enter, and traffic stop
signs.
If the vehicle speed exceeds the speed limit sign indicated in the active driving display/
instrument cluster while the vehicle is driven, the system noti fies the driver using the
indication in the active driving display/instrument cluster and a warning sound.

Distance & Speed Alert(DSA)
*
▼Distance & Speed Alert (DSA)
The DSA is a system which provides
advice for maintai
ning the appropriate
distance between vehicles and notifies the
driver of the recommended, safe distance
to maintain with a vehicle ahead. The
system measures the distance between
your vehicle and a vehicle ahead while the
vehicle speed is about 30 km/h (19 mph)
or faster. If the distance between your
vehicle and a vehicle ahead is close, the
system alerts the driver of a possible
collision using an indication on the
display.
WA R N I N G
Do not rely completely on the DSA:
The ability of the system to detect a vehicle
ahead is limited depending on the type of
vehicle ahead, weather conditions, or
traffic conditions. In addition, the system is
not for maintaining the distance between
your vehicle and a vehicle ahead. If you
neglect to operate the accelerator and
brake pedals correctly, it could lead to an
accident. Always check the safety of the
surrounding area and depress the brake
pedal or accelerator pedal while keeping a
safe distance from vehicles ahead or
on-coming vehicles.
Operation conditions
The DSA operates when the following
conditions are all met.
The ignition is switched ON.
The DSA is turned on.
The shift lever (manual transmission
vehicle) or the selector lever (automatic
transmission vehicle) is in a position
other than R.
The vehicle speed is about 30 km/h (19
mph) or faster.
i-ACTIVSENSE status symbol
(warning/risk avoidance support system)
(green) is displayed.
NOTE
The objects which activate the system
are four-wheeled vehicles.
The DSA may also operate in the
presence of motorcycles and bicycles.
The DSA may not operate normally
when the speed of a vehicle ahead is too
slow.
The system does not operate with the
following objects.
Vehicles approaching in the opposite
direction.
Stationary objects (stopped vehicles,
obstructions)
The DSA can be set to inoperable.

automatically enabled the next time the
ignition is switched ON. However, if the
system is canceled using the
personalization features, the system is not
automatically enabled.
Rear Cross Traffic Alert
(RCTA)
*
▼Rear Cross Traffic Alert (RCTA)
The RCTA system is des
igned to assist the
driver in checking the area to the rear left
and right sides of your vehicle while your
vehicle is reversing by alerting the driver
to the presence of vehicles approaching
the rear of your vehicle.
The RCTA system detects vehicles
approaching from the rear left and right
sides of your vehicle and the rear of your
vehicle while your vehicle is being
reversed out of a parking space, and
notifies the driver of possible danger using
the Blind Spot Monitoring (BSM) warning
indicator lights and the warning buzzer.

To resume driving
After the vehicle ahead starts moving
while your vehicle is stopped under stop
hold control, press the RE S switch or
depress the accelerator pedal to cancel the
stop hold control and start driving.
NOTE
When you resume driving by pressing
the RES switch, your vehicle does not
start moving until the distance between
your vehicle and the vehicle ahead
lengthens to the specified distance or
farther.
If the TJA is temporarily canceled,
depress the accelerator pedal and start
driving the vehicle. If the TJA is
temporarily canceled, you cannot
resume driving by pressing the RES
switch when there are no vehicles in
front of your vehicle.
If the vehicle ahead starts moving within
3 seconds after your vehicle is stopped
by the stop hold control, headway
control will continue even if you do not
resume driving your vehicle, such as by
depressing the accelerator pedal.

Vehicle departur e information
If you do not resume driving within a few
seconds after the vehicle ahead starts
moving during stop hold control, the
multi-information display vehicle-ahead
indication flashes to urge the driver to
resume driving. If you do not resume
driving after the indicator light flashes, a
sound is activated to urge you to resume
driving.
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 (ye
llow 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.
1. Forward sensing camera (FSC)
WA R N I N G
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.

1. Forward Sensing Camera (FSC)

The Forward Sensing Camera (FSC)
determines the conditions ahead of the
vehicle while traveling at night and detects
traffic lanes. The distance in which the
Forward Sensing Camera (FSC) can detect
objects varies depending on the
surrounding conditions.
WA R N I N G
Do not modify the suspension:
If the vehicle height or inclination is
changed, the system will not be able to
correctly detect vehicles ahead. This will
result in the system not operating normally
or mistakenly operating, which could cause
a serious accident.
CAUTION
 Do not apply accessories, stickers or film
to the windshield near the Forward
Sensing Camera (FSC).
If the area in front of the Forward
Sensing Camera (FSC) lens is obstructed,
it will cause the system to not operate
correctly. Consequently, each system
may not operate normally which could
lead to an unexpected accident.
 Do not disassemble or modify the
Forward Sensing Camera (FSC).
Disassembly or modification of the
Forward Sensing Camera (FSC) will cause
a malfunction or mistaken operation.
Consequently, each system may not
operate normally which could lead to an
unexpected accident.
