i-ACTIVSENSE*
i-ACTIVSENSE is a collective term covering a series of advanced safety and driver support
systems which make use of a Forward Sensing Camera (FSC) and radar sen\
sors.
Because each system has its limitations, always drive carefully and do not rely solely on the
systems.

High Beam Control System (HBC)*
The High Beam Control System (HBC) determines the conditions in front of the vehicle
using the Forward Sensing Camera (FSC) while driving in darkness to au\
tomatically switch
the headlights between high and low beams.
Refer to Warning/Indicator Lights on page 4-16.
While driving the vehicle at a speed of about 30 km/h (18 mph), the he\
adlights are switched
to high beams when there are no vehicles ahead or approaching in the opp\
osite direction.
The system switches the headlights to low beams when one of the followin\
g occurs:
 The system detects a vehicle or the headlights/lights of a vehicle appro\
aching in the
opposite direction. The vehicle is driven on roads lined with streetlamps or on roads in wel\
l-lit cities and
towns. The vehicle is driven at less than about 20 km/h (12 mph).
F orward Sensing
Camera (FSC)
The recognition distance of the
F
orward Sensing Camera (FSC)

*Some models.
Lane Departure Warning System (LDWS)*
The LDWS system notifies the driver that the vehicle may be deviating from its lane.
The system detects the white or yellow lines on the traffic lane using the Forward Sensing
Camera (FSC) and if it determines that the vehicle may be deviating from its lane, it notifies
the driver by flashing the LDWS warning light and activating the LDWS warning beep.
Use the LDWS when you drive the vehicle on roads with white or yellow li\
nes.
Refer to Forward Sensing Camera on page 4-84.
Forward Sensing Camera

LD WS warning light
The warning light illuminates when the system has a malfunction.
Refer to Warning Lights on page 4-16.
WARNING
Do not use the LDWS under the following conditions:
The system may not operate adequately according to the actual driving conditions,
resulting in an accident.
 Driving on roads with tight curves. Driving under bad weather conditions (rain, fog, and snow).
The functions of the LDWS have limitations:
Always stay on course using the steering wheel and drive with care. The system is not
designed to compensate for a driver’s lack of caution and if you rely too much on the
LDWS it could lead to an accident. The driver is responsible for assuring lane changes and
other maneuvers. Always pay attention to the direction in which the vehicle is traveling
and the vehicle’s surroundings.

CAUTION
Do not modify the suspension. If the vehicle height or the damping force of the
suspensions is changed, the LDWS may not operate correctly.
NOTE
 If your vehicle deviates from its traffic lane, the LDWS operates (warning sound and
indicator light). Steer the vehicle adequately to drive the vehicle to \
the center of the lane. When the turn signal lever is operated for a lane change, the LDWS warni\
ng is
automatically canceled. The LDWS warning becomes operable when the turn \
signal lever
is returned and the system detects the white or yellow lines. If the steering wheel, accelerator pedal, or brake pedal is operated abr\
uptly and the
vehicle moves close to a white or yellow line, the system determines tha\
t the driver is
making a lane change and the LDWS warning is automatically canceled. The LDWS may not operate during the period immediately after the vehicle\
has deviated
from its lane and the LDWS has operated, or the vehicle deviates from its lane repeatedly
within a short period of time. The LDWS does not operate if it does not detect the white or yellow lines of the traffic
lane.

when the LDWS switch is pressed and
the LDWS OFF indicator light in the
instrument cluster turns off.
2. Drive the vehicle in the center of the
driving lane while the LDWS OFF
indicator light is turned off. The system
becomes operational when all of the
following conditions are met.
 The vehicle is driven in the center
of the driving lane with the white or
yellow lines on the left and right sides,
or on either side. The vehicle speed is 65 km/h (41 mph)
or faster. The vehicle is driven on a straight road
or road with gentle curves.
The LDWS does not operate in the
following cases:
 The system cannot detect white or
yellow lines. The vehicle speed is less than 60 km/h
(37 mph). The vehicle is making a sharp turn. The vehicle is making a curve at an
inadequate speed.
NOTE
 The LDWS does not operate until the
system detects a white or yellow line on
either the left or right. When the system detects a white or
yellow line on one side only, the system
will activate the warning only when the
vehicle deviates on the side where the
white or yellow line is being detected. The distance and warning sensitivity
(likelihood of a warning) which the
system uses to determine the possibility
of a lane departure can be changed.
Refer to Personalization Features on
page 9-9.
Auto cancel
In the following cases, the LDWS cancels
automatically and the LDWS warning
light in the instrument cluster turns on.
 The temperature inside the camera is
high or low. The windshield around the camera is
foggy. The windshield around the camera is

wheel appropriately and steer the vehicle
to the center of the lane.
NOTE
 If the LDWS warning sound is set to
rumble*1, the sound will be heard from
the vehicle speaker on the side which
the system determined the vehicle may
be deviating from its lane. It may be difficult to hear the LDWS
warning beep depending on the
surrounding conditions such as outside
noise. The volume of the LDWS warning sound
can be changed.
Refer to Personalization Features on
page 9-9. The type of warning sound (rumble*1/
beep) on the LDWS can be changed.

*1 A rumble strip is a series of grooves
in the road pavement surface
positioned at specific intervals,
and when the vehicle passes over
it a vibration and rumble sound is
produced which alerts the driver
that the vehicle is departing from the
lane.
The rumble sound is a reproduction
of the sound which occurs when a
vehicle passes over a rumble strip.

Blind Spot Monitoring (BSM) System*
The Blind Spot Monitoring (BSM) system is designed to assist the driver in checking the
area to the rear of the vehicle on both sides during lane changes by ale\
rting the driver to the
presence of vehicles approaching from the rear in an adjacent lane.
The Blind Spot Monitoring (BSM) system 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 turns on the
Blind Spot Monitoring (BSM) warning lights equipped on the door mirrors depending on
the conditions. If the turn signal lever is operated to signal a lane ch\
ange in the direction
in which the Blind Spot Monitoring (BSM) warning light is illuminated, the system warns
the driver of a vehicle in the detection area by flashing the Blind Spot Monitoring (BSM)
warning light and activating a beep sound.
The detection area on this system covers the driving lanes on both sides\
of the vehicle and
from the rear part of the doors to about 50 m (164 ft) behind the vehi\
cle.
Detection areas Your v ehicle
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
Blind Spot Monitoring (BSM) warning light may not flash or it 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.
