i-ACTIVSENSE*
i-ACTIVSENSE is a collective term covering a series of advanced safety and driver support
systems which make use of a Forw ard Sensing Camera (FSC) and radar sensors. These
systems consist of active safety and pre-crash safety systems.
These systems are designed to ass ist the driver in safer driving by reducing the load on the
driver and helping to avert col lisions or reduce their severity. However, because each system
has its limitations, always drive carefully and do not rely sol ely on the systems.

Blind Spot Monitoring (BSM)*
The BSM is designed to assist the driver in checking the area to the rear of the vehicle on
both sides during lane changes by notifying the driver of the p resence of vehicles
approaching from the rear in an adjacent lane.
The BSM detects vehicles approaching from the rear while travel ing in the forward
direction at a speed of 10 km/h (6.3 mph) or faster and notifie s the driver by turning on the
BSM warning indicator light and displaying the vehicle detectio n screen (vehicles with
multi-information display and active driving display).
If the turn signal lever is operated to signal a turn in the direction in which the BSM
warning indicator light is illumi nated while the approaching vehicle is detected, the BSM
notifies the driver of possible danger by turning on the BSM wa rning indicator light, and by
activating the warning sound and the warning screen indicator display (vehicles with
multi-information display and active driving display).
The detection area on this system covers the driving lanes on b oth sides of the vehicle and
from the rear part of the front d oors to about 50 m (164 ft) behind the vehicle.
Detection areas
Your vehicle
WA R N I N G
Always check the surrounding area visually before making an actual lane change:
The system is only designed to assist you in checking for vehicles at your rear when making a
lane change. Due to certain limitations with
the operation of this system, the BSM warning
indicator light, the warning sound and the warning screen indicator display may not activate
or they might be delayed even though a vehicle is in an adjacent driving lane. Always make it
your responsibility as a driver to check the rear.

Lane-keep Assist System (LAS) & Lane DepartureWarning System (LDWS)
*
The LAS&LDWS alerts the driver th at the vehicle may be deviating from its lane and it
provides steering assistance to help the driver stay within the vehicle lanes.
The Forward Sensing Camera (FSC) detects the white lines (yello w lines) of the vehicle
lane in which the vehicle is traveling and if the system determ ines 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 activating a la ne departure warning sound,
vibrating the steering wheel, and indicating an alert in the di splay. Use the system when you
drive the vehicle on ro ads with white (yellow) lines such as ex pressways and highways.
Refer to Forward Sensing Camera (FSC) on page 4-145.

Do not rely completely on the LAS&LDWS:
 The LAS&LDWS is not an automatic driving syst em. 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 detection ability of the LAS&LDWS is limite d. Always stay on course using the steering
wheel and drive with care.
Do not use the LAS&LDWS in the following cases:
The system may not operate adequately accordin g to the actual driving conditions, resulting
