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 illuminates or flashes when the system has a malfunction.
Refer to Warning/Indicator 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 insufficient 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 Distance Recognition Support System (DRSS) measures the distance between your vehicle and a vehicle ahead using a radar sensor (front) while the vehicle speed is 30 km/h or faster (19 mph or faster), and indicates a recommended distance to maintain between the vehicles. Furthermore, if your vehicle approaches a vehicle ahead more closely than the appropriate distance to maintain between the vehicles, the vehicle-ahead indication in the multi-information display or the active driving display (with active driving display) is flashed to advise the driver to keep a safer distance from the vehicle ahead.
Do not rely completely on the Distance Recognition Support System (DRSS) and always drive carefully:
The Distance Recognition Support System (DRSS) provides advice for safer driving and notifies the driver of a recommended, safer distance to maintain with a vehicle ahead. The ability to detect a vehicle ahead is limited depending on the type of vehicle ahead, the weather conditions, and the traffic conditions. Therefore, if the accelerator and brake pedals are not operated correctly it could lead to an accident. Always verify the safety of the surrounding area and depress the brake pedal or accelerator pedal while keeping a safer distance from vehicles ahead or on-coming vehicles.
The Distance Recognition Support System (DRSS) operates when all of the following conditions are met:
The ignition is switched ON.
The Distance Recognition Support System (DRSS) is on.
The selector lever is in a position other than reverse (R).
The vehicle speed is 30 km/h or faster (19 mph or faster).
The objects which activate the system are 4-wheeled vehicles.
The Distance Recognition Support System (DRSS) may also operate in the presence of motorcycles and bicycles.
The Distance Recognition Support System (DRSS) may not operate normally under the following conditions:
The Dynamic Stability Control (DSC) has a malfunction.
The vehicle ahead is travelling at an extremely slow speed.
The system does not operate with the following objects:
Vehicles approaching in the opposite direction.
Stationary objects (stopped vehicles, obstructions)
The Distance Recognition Support System (DRSS) operation status is displayed in the multi-information display or the active driving display (with active driving display).
Problems are indicated in the centre display. If there is a problem, take appropriate action according to the displayed message.
Refer to Warning/Indicator Lights (Search).
When the ignition is switched off, the operation status before the system was turned off is maintained. For example, if the ignition is switched off with the Distance Recognition Support System (DRSS) operable, the system will be operable when the ignition is switched ON the next time.
The Distance Recognition Support System (DRSS) can be turned on/off and the system's sensitivity can be changed.
