*Some models.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 darknes s to automatically switch
the headlights between high and low beams.
Refer to Warning/Indicator Lights on page 4-18 .
While driving the vehicle at a speed of about 30 km/h (19 mph) or more, the headlights are
switched to high beams when there are no vehicles ahead or approaching in the opposite
direction.
The system switches the headlights to low beams when one of the following occurs: 
The system detects a vehicle or the headlights/lights of a vehicle approaching in the
opposite direction. 
The vehicle is driven on roads lined with streetlamps or on roads in well-lit cities and
towns. 
The vehicle is driven at less than about 20 km/h (12 mph).
Forward Sensing
Camera (FSC)The recognition distance of the
Forward Sensing Camera (FSC)
varies according to the
surrounding conditions.
The warning light turns on when the system has a malfunction.
Refer to Warning Indication/Warning Lights on page 4-26 .
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 High Beam Control System (HBC) and drive the vehicle while
paying sufficient attention to safety. Switch the headlights between the high beams and
low beams manually if necessary.

*Some models.Lane Departure Warning System (LDWS) *
The LDWS system notifies the driver that the vehicle may be devi ating 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 devia ting from its lane, it notifies
the driver by flashing the LDWS warning light and activating the LDWS warning beep, and
by the multi-information display (vehicles with multi-information display).
Use the LDWS when you drive the vehicle on roads with white or yellow lines.
Refer to Forward Sensing Camera on page 4-95 . Forward Sensing Camera
(FSC)
The warning light illuminates when the system has a malfunction.
Refer to Warning Indication/Warning Lights on page 4-26 .
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 warning 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 abruptly and the
vehicle moves close to a white or yellow line, the system determines that 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 ye llow lines of the traffic
lane.

*Some models.Blind Spot Monitoring (BSM) System *
The Blind Spot Monitoring (BSM) is designed to assist the drive r in checking the area to the
rear of the vehicle on both sides during lane changes by alerting the driver to the presence of
vehicles approaching from the rear in an adjacent lane.
The Blind Spot Monitoring (BSM) detects vehicles approaching fr om 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 change in the direction
in which the Blind Spot Monitoring (BSM) warning light is illum inated, the system warns
the driver of a vehicle in the detection area by flashing the Bl ind 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 vehicle.
Detection areasYour vehicle
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.
