*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 darkness to automatically switch
the headlights between high and low beams.
Refer to Warning/Indicator Lights on page 4-31 .
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 fl ashes when the system has a malfunction.
Refer to Warning Indication/Warning Lights on page 4-32 .
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 suffi cient 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 traffi c
conditions.
 


 When there are sources of light in the area such as street lamps, illuminated signboards,
and traffi c signals.




 When there are refl ective objects in the surrounding area such as refl ective 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 suffi cient darkness such as at dawn or dusk.



 When the 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 High Beam Control System (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 high beam position.
The High Beam Control System (HBC)
determines that it is dark based on the
brightness of the surrounding area. At the
same time, the High Beam Control System
(HBC) indicator light (green) in the
instrument cluster illuminates.



NOTE
  When the vehicle speed is about
30 km/h (19 mph) or more, the
headlights automatically switch to
high beams when there are no vehicles
ahead or approaching in the opposite
direction.
 When the vehicle speed is less than
about 20 km/h (12 mph), the High Beam
Control System (HBC) switches the
headlights to low beams.
 


 The low beams may not switch to high
beams when cornering.
 


 Operation of the High Beam Control
System (HBC) function can be disabled.
Refer to Personalization Features on
page 9-11 .

Manual Switching
Switching to low beams
Shift the lever to the low beam position.
The High Beam Control System (HBC)
indicator light (green) turns off.
Switching to high beams
Turn the headlight switch to the

position.
The High Beam Control System (HBC)
indicator light (green) turns off and the

is illuminated.

*Some models.
Blind Spot Monitoring (BSM) *
The Blind Spot Monitoring (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.
The Blind Spot Monitoring (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 notifi es
the driver by turning on the Blind Spot Monitoring (BSM) warning indicator light and
displaying the vehicle detection 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 Blind Spot
Monitoring (BSM) warning indicator light is illuminated while the approaching vehicle is
detected, the Blind Spot Monitoring (BSM) notifi es the driver of possible danger by turning
on the Blind Spot Monitoring (BSM) warning 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 both sides of the vehicle and
from the rear part of the front doors to about 50 m (164 ft) behind the vehicle.

Detection areas Your 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 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.
