*1 The recognition distance of the ForwardSensing Camera (FSC) varies according to
the surrounding conditions.
The warning light turns on when the
system has a malfunction.
Refer to High Beam Control System
(HBC) Warning Indication/Warning
Light (Amber) on page 7-34.
CAUTION
Do not adjust the vehicle height,
modify the headlight units, or
remove the camera, otherwise the
system will not operate normally.
 Do not rely excessively on the HBC
and drive the vehicle while paying
su fficient attention to safety. Switch
the headlights between the high
beams and low beams manually if
necessary.
NOTE
The timing in which the system
switches the headlights changes under
the following conditions. If the system
does not switch the headlights
appropriately, manually switch
between high and low beams
according to the visibility as well as
road and tra ffic conditions.
When there are sources of light in
the area such as street lamps,
illuminated signboards, and tra ffic
signals.
When there are re flective objects in
the surrounding area such as
re flective plates and signs.
When visibility is reduced under rain,
snow and foggy conditions.
When driving on roads with sharp
turn or hilly terrain.
When the headlights/rear lamps of
vehicles in front of you or in the
opposite lane are dim or not
illuminated.
When there is insu fficient darkness
such as at dawn or dusk.
When the trunk/luggage
compartment is loaded with heavy
objects or the rear passenger seats
are occupied.
When visibility is reduced due to a
vehicle in front of you spraying water
from its tires onto your windshield.
▼ To Operate the System
The HBC operates to switch the
headlights automatically between high
and low beams after the ignition is
switched ON and the headlight switch
is in the AUTO and low beam position.
The HBC determines that it is dark
based on the brightness of the
surrounding area. At the same time,
the HBC indicator light (green) in the
instrument cluster illuminates.

NOTE
Operation of the HBC function can be
disabled.
Refer to the Settings section in the

Blind Spot Monitoring(BSM)
*
▼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
presence of vehicles approaching from
the rear in an adjacent lane.
BSM operation
The BSM detects vehicles approaching
from the rear while traveling in the
forward direction at a speed of 10
km/h (6.3 mph) or faster and noti
fies
the driver by turning on the BSM
warning indicator light and displaying
the vehicle detection screen.
If the turn signal lever is operated to
signal a turn in the direction in which
the BSM warning indicator light is
illuminated while the approaching
vehicle is detected, the BSM notifies
the driver of possible danger flashing
on the BSM warning indicator light,
and by activating the warning sound
and the warning screen indicator
display.
The detection area on this system
covers the driving lanes on both sides
of the vehicle and from the rear part of
the front doors to about 50 m (164 ft)
behind the vehicle.
1. Your vehicle
2. Detection areas
WARNING
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, th e 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.
NOTE
The BSM will operate when all of the
following conditions are met:
The ignition is switched ON.The i-ACTIVSENSE warning
indication/warning light in the

The DM is a system which detects
driver fatigue and sleepiness, and
encourages the driver to take a rest.
While driving the vehicle at about 5
km/h (3 mph) or faster, the DM
detects changes in the driver's facial
features using the driver monitoring
camera. The system then estimates the
amount of accumulated fatigue and
sleepiness of the driver and encourages
the driver to take a rest using a warning
indication in the instrument cluster and
a warning sound.
Two types of warning indication
patterns are set for notifying the driver
based on the estimated amount of
accumulated fatigue and sleepiness of
the driver.
Fatigue and sleepiness are detected:
Warning pattern (caution)
Much more fatigue and sleepiness
are detected: Warning pattern
