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 4-40 .
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

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. At the same time,
the High Beam Control System (HBC)
indicator light (green) in the instrument
cluster illuminates.
The High Beam Control System (HBC)
determines that it is dark based on the
brightness of the surrounding area.
NOTE
  When the vehicle speed is 30 km/h
(18 mph) or higher, 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 Personalisation
Features on page 9-16 .

 The DSC is not malfunctioning. 

 The Smart City Brake Support (SCBS) detects a vehicle ahead by emitting a near-
infrared laser beam and receiving the beam refl ected off the refl ector of the vehicle
ahead, and then using it for the measurement. Consequently, the Smart City Brake
Support (SCBS) may not operate under the following conditions:
 


 Refl ection of the laser is poor due to the shape of the vehicle ahead.



 The vehicle ahead is signifi cantly dirty.



 Under bad weather condition, such as rain, fog and snow.



 The window washer is being used or the windscreen wipers are not used when it's
raining.
 


 The windscreen is dirty.



 The steering wheel is turned completely left or right, or the vehicle is accelerated
rapidly and comes close to the vehicle ahead.
 


 Trucks with low loading platforms and vehicles with an extremely low or high
profi le.




 Vehicles with certain shapes such as a vehicle carrier. 

 Under the following conditions, the Smart City Brake Support (SCBS) system may not
operate normally.
 


 Heavy luggage is loaded in the luggage compartment or on the rear seat.



 If there is the possibility of partial contact with a vehicle ahead.



 When driving on continuously curving roads, and entering and exiting exits.



 Elongated luggage or cargo is loaded onto installed roof rails and covers the laser
sensor (front).

Interior Features
Audio System
Signals from an FM transmitter are similar
to beams of light because they do not
bend around corners, but they do refl ect.
Unlike AM signals, FM signals cannot
travel beyond the horizon. Therefore, FM
stations cannot be received at the great
distances possible with AM reception.
AM wave FM wave
FM wave
100—200 km (60—120 miles) Ionosphere
Atmospheric conditions can also affect
FM reception. High humidity will cause
poor reception. However, cloudy days may
provide better reception than clear days.
Multipath noise
Since FM signals can be refl ected by
obstructions, it is possible to receive both
the direct signal and the refl ected signal
at the same time. This causes a slight
delay in reception and may be heard as a
broken sound or a distortion. This problem
may also be encountered when in close
proximity to the transmitter.
Reflected wave
Direct
Flutter/Skip noise
Signals from an FM transmitter move in
straight lines and become weak in valleys
between tall buildings, mountains, and
other obstacles. When a vehicle passes
through such an area, the reception
conditions may change suddenly, resulting
in annoying noise.
Weak signal noise
In suburban areas, broadcast signals
become weak because of distance from the
transmitter. Reception in such fringe areas
is characterised by sound breakup.
