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 4-36 .
While driving the vehicle at a speed of about 30 km/h (18 mph), 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.

Lane Departure Warning System (LDWS) *
The LDWS system notifi es the driver that the vehicle may be deviating from its lane.
The system detects the white or yellow lines on the traffi c lane using the forward sensing
camera and if it determines that the vehicle may be deviating from its lane, it notifi es the
driver using the active driving display (vehicles with active driving display), and by fl ashing
the LDWS warning light and activating the LDWS warning beep.
Use the LDWS when you drive the vehicle on roads with white or yellow lines.
Refer to Forward Sensing Camera on page 4-148 .

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 manoeuvres. Always pay attention to the direction in which the vehicle is
travelling 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 traffi c lane, the LDWS operates (warning sound and
indicator light). Steer the vehicle adequately to drive the vehicle to the centre of the
lane.
  When the direction indicator lever is operated for a lane change, the LDWS warning
is automatically cancelled. The LDWS warning becomes operable when the direction
indicator 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 cancelled.
  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 traffi c
lane.

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 Personalisation Features on
page 9-13 .
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 windscreen around the camera is
foggy.
 


 The windscreen around the camera is
blocked by an obstruction, causing poor
forward visibility.
For vehicles equipped with the active
driving display, the lane (border lines) is
indicated in the display. The LDWS is
enabled automatically when the operation
conditions are met, and the LDWS
warning light turns off.
Auto cancel warning
When the following operations are
performed, the LDWS determines that
the driver intends to make a lane change
and the LDWS warning is cancelled
automatically. The LDWS is enabled
automatically after the driver performs the
operation.
 


 The steering wheel is operated abruptly.



 The brake pedal is depressed abruptly.



 The accelerator pedal is depressed
abruptly.
 


 The direction indicator lever is operated
(after the direction indicator lever is
returned, the LDWS may not operate for
about 3 seconds which is the period of
time required to make a lane correction).
NOTE
After about 60 seconds have elapsed
with the direction indicator lever left
operating, the LDWS warning may
operate if the vehicle is close to a white
or yellow line.
Cancelling The System
Press the LDWS switch to cancel the
LDWS. The LDWS OFF indicator light
turns on.
For vehicles with the active driving
display, the driving lane indication in the
active driving display is not indicated
when the LDWS is cancelled.

warning beep activates and the LDWS
warning light fl ashes. Operate the steering
wheel appropriately and steer the vehicle
to the centre of the lane.
For vehicles equipped with the active
driving display, if there is the possibility of
a lane departure, the system indicates the
direction it determines that the vehicle is
deviating in the active driving display.
Indication on display
NOTE
  If the LDWS warning sound is set to
rumble, 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 diffi cult to hear the LDWS
warning beep depending on the
surrounding conditions such as
outside noise.

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 alerting 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
travelling in the forward direction at a speed of 30 km/h (19 mph) or faster and turns on
the Blind Spot Monitoring (BSM) warning lights equipped on the door mirrors depending
on the conditions. If the direction indicator lever is operated to signal a lane change 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 fl ashing 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 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 light may not fl ash 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.
