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 (Search).
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).
The warning light flashes when the system has a malfunction.
Refer to Warning Lights (Search).
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.
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 traffic conditions.
When there are sources of light in the area such as street lamps, illuminated signboards, and traffic signals.
When there are reflective objects in the surrounding area such as reflective plates and signs.
When visibility is reduced under rain, snow and foggy conditions.
When driving on roads with sharp curves 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 sufficient 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 tyres onto your windscreen.
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.
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 (Search).
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.
The system goes on operation standby when the LDWS switch is pressed and the LDWS OFF indicator light in the instrument cluster turns off. For vehicles equipped with the active driving display, the driving lane (border lines) is indicated in the display.
Indication on display
Drive the vehicle in the centre of the driving lane while the LDWS OFF indicator light is turned off. The system becomes operational when all of the following conditions are met.
The vehicle is driven in the centre of the driving lane with the white or yellow lines on the left and right sides, or on either side.
The vehicle speed is 70 km/h (44 mph) or faster.
The vehicle is driven on a straight road or road with gentle curves.
For vehicles equipped with the active driving display, the driving lane is indicated in the display.
Indication on display
The LDWS does not operate in the following cases:
The system cannot detect white or yellow lines.
The vehicle speed is less than 65 km/h (40 mph).
The vehicle is making a sharp curve.
The vehicle is making a curve at an inadequate speed.
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 (Search).
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).
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.
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.
If the system determines that there is the possibility of a lane departure, the LDWS warning beep activates and the LDWS warning light flashes. 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
If the LDWS warning sound is set to rumble*1, 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 difficult to hear the LDWS warning beep depending on the surrounding conditions such as outside noise.
The volume of the LDWS warning sound can be changed.
Refer to Personalisation Features (Search).
The type of warning sound (rumble*1/beep) on the LDWS can be changed.
Refer to Personalisation Features (Search).
A rumble strip is a series of grooves in the road pavement surface positioned at specific intervals, and when the vehicle passes over it a vibration and rumble sound is produced which alerts the driver that the vehicle is departing from the lane.
The rumble sound is a reproduction of the sound which occurs when a vehicle passes over a rumble strip.
