The Automatic High Beam can be operated when
The power switch is in ON mode. ■
Camera sensor dete ction information●
High beam may not be automatically tu rned off in the following situations:
• When oncoming vehicles sudd enly appear from a curve
• When the vehicle is cut in front of by another
• When oncoming or preceding vehicles are hidden from sight due to repeated
curves, road dividers or roadside trees ●
High beam may be turned off if an oncoming vehicle that is using fog lights without
using the headlights is detected. ●
House lights, street lights, red traffic sign als, and illuminated billboards or signs may
cause the high beam to turn off. ●
The following factors may affect the amount of time taken to turn high beam on or off:
• The brightness of headlights, fog lights, and tail lights of oncoming and preceding
vehicles
• The movement and direction of oncoming and preceding vehicles
• When a oncoming or preceding vehicle on ly has operational lights on one side
• When a oncoming or preceding vehicle is a two-wheeled vehicle
• The condition of the road (gradient, curve, condition of the road surface, etc.)
• The number of passengers and amount of luggage ●
High beam may be turned on or off when unexpected by the driver.●
In the situations below, you should consider turning the high beams on or off manually
rather than relying on the Automatic High Beam system.
• The system is not able to correctly dete ct the surrounding brightness levels, and
flashes or exposes nearby pe destrians to the high beam.
• In bad weather (rain, snow , fog, sandstorms, etc.)
• The windshield is obscured by fog, mist, ice, dirt, etc.
• The windshield is cracked or damaged.
• The camera sensor is deformed or dirty.
• The camera sensor temperature is extremely high.
• Surrounding brightness levels are equal to those of headlights, ta il lights or fog lights.
• Vehicles ahead have headlights or tail lights that are either switched off, dirty, are
changing color, or are not aimed properly.
• When driving through an area of intermit tently changing brightness and darkness.
• When frequently and repeatedly driving ascending/descending roads, or roads with
rough, bumpy or uneven surfaces (such as stone-paved roads, gravel tracks, etc.).
• When frequently and repeat edly taking curves or driving on a winding road.
• There is a highly reflective object ahead of the vehicle, such as a sign or a mirror.
• The back of a vehicle ahead is highly reflective, such as a container on a truck.
• The vehicle’s headlights are damaged or dirty.
• The vehicle is listing or titling, due to a flat tire, a trailer being towed, etc.
• The driver believes that the high beam may be causing problems or distress to other
drivers or pedestrians nearby.

NX300h_U_OM78007ULDA (Lane Departure Alert with steering control) While driving on a highway or freeway that has white (or yellow) lane markers
and few curves, a camera, which is located on the upper part of the windshield,
uses this system to recognize the white (yellow) lane markers and when the
driver has deviated from the lane. If the system judges that the vehicle has devi-
ated from the current traffic lane, along with alerting the driver with a buzzer and
indications in the multi-information display, it will provide assistance by operating
the steering wheel to avoid further deviation from the marker lines.

NX300h_U_OM78007U ◆ Lane deviation alert function
When the system judges that the vehicle is deviating from the current traffic lane,
an alert buzzer sounds and it prompts cautions from the display screen of the
multi-information display. When the alert buzzer sounds, please ch eck the surrounding road situation and
return near the center of the white (yello w) lane markers by safely operating the
steering wheel.
◆ Steering control function
If the system judges that the vehicle has de viated from the current traffic lane, it is
displayed in the multi-information displa y and steering force is supplied to the
steering wheel by the steering control, pr oviding required assistance in steering
wheel operation to avoid further deviation from the marker lines. In order to prevent over relying on the system, when the system does not operate the
steering wheel and driving where hands are lightly supporting the steering wheel
continues, a warning message is displa yed on the multi-information display.Functions included with LDA Alert buzzer
