When Driving
i-ACTIVSENSE
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 Personalisation
Features on page 9-13 .
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.
Adaptive LED Headlights (ALH) *
The Adaptive LED Headlights (ALH) are a system which uses the Forward Sensing Camera
(FSC) to determine the situation of a vehicle ahead or a vehicle approaching in the opposite
direction while driving at night to automatically switch the illumination range of the
headlights, the illuminated area, or the illumination brightness.
Refer to Forward Sensing Camera (FSC) on page 4-179 .
The Adaptive LED Headlights (ALH) are controlled between high and low beams as follows
to assure the driver’s visibility without dazzling a vehicle ahead or a vehicle approaching in
the opposite direction.
Glare-Free High Beam
This feature dims only the high-beam light shone on the vehicle ahead.
The high beams will dim while driving at a speed of about 40 km/h (25 mph) or faster.
When the vehicle speed is less than about 30 km/h (18 mph), the beams switch to the low
beams.


NOTE
The headlight high-beam indicator light turns on while the high beams are on.

When Driving
i-ACTIVSENSE
Wide-Range Low Beam
This feature extends the illumination range of the light cast by the low beams while driving
at a speed less than about 40 km/h (25 mph).


Highway Mode
This feature shifts the illumination angle of the light cast by the headlights upward while
driving on highways.


The distance in which the Adaptive LED Headlights (ALH) can detect objects varies
depending on the surrounding conditions.
CAUTION
  Do not modify the suspensions or headlight units, or remove the camera. Otherwise,
the Adaptive LED Headlights (ALH) may not operate normally.
  Do not rely excessively on the Adaptive LED Headlights (ALH) and drive the vehicle
while paying suf¿ cient attention to safety. Switch the headlights between the high
beams and low beams manually if necessary.

When Driving
i-ACTIVSENSE
NOTE
Under the following conditions, the Adaptive LED Headlights (ALH) may not operate
normally. Manually switch between the high and low beams according to the visibility,
and the road and traf¿ c conditions.


 When there are other sources of light in the area such as street lamps, illuminated
signboards, and traf¿ c signals.

 When there are reÀ ective objects in the surrounding area such as reÀ ective plates and
signs.
  When visibility is reduced under rain, snow and foggy conditions. 
 When driving on roads with sharp curves or undulations. 
 When the headlights/rear lamps of vehicles ahead or in the opposite lane are dim or not
illuminated.
  When there is insuf¿ 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 ahead spraying water from its tyres onto
your windscreen.
To Operate the System
The system switches the headlights to the
high beams after the ignition is switched
ON and the headlight switch is in the

position. The Adaptive LED Headlights
(ALH) indicator light (green) in the
instrument cluster turns on simultaneously.


The Adaptive LED Headlights (ALH)
determine that it is nighttime based on the
brightness of the surrounding area.
The system cancels operation when the
headlight switch is turned to a position
other than
, the headlights are
manually switched to low beams, or the
high beams are À ashed on and off.
NOTE
The system can be changed so that the
Adaptive LED Headlights (ALH) do not
operate.
Refer to Personalisation Features on
page 9-13 .
Manual Switching
Switching to low beams
Shift the lever to the low beam position.
The Adaptive LED Headlights (ALH)
indicator light (green) turns off.
Switching to high beams
Turn the headlight switch to the

position.
The Adaptive LED Headlights (ALH)
indicator light (green) turns off and the

is illuminated.

Forward Sensing Camera (FSC)

The Forward Sensing Camera (FSC) determines the conditions ahead of the vehicle while
travelling at night and detects traf¿ c lanes. The distance in which the Forward Sensing
Camera (FSC) can detect objects varies depending on the surrounding conditions.
WARNING
Do not modify the suspension:
If the vehicle height or inclination is changed, the system will not be able to correctly
detect vehicles ahead. This will result in the system not operating normally or
mistakenly operating, which could cause a serious accident.
