■Daytime running light system
●To make your vehicle more visible to other drivers during daytime driving, the daytime
running lights turn on automatically (at an in creased intensity) whenever the hybrid sys-
tem is started and the parking brake is releas ed with the headlight switch off or in the
“AUTO” position. (Illuminate brighter than the front parking lights.) Daytime running
lights are not designed for use at night.
Type A only: Daytime running lights can be turned off by operating the switch.
●If a turn signal light is in use, the daytime running light, on the same side, is turned off.
For emergency flashers, both are turned off.
●Compared to turning on the headlights, the daytime running light system offers greater
durability and consumes less electricity, so it can help improve fuel economy.
■Headlight control sensor
■Automatic light off system
●When the headlights come on: The headlights and tail lights turn off 30 seconds after a
door is opened and closed if the power switch is turned to ACCESSORY mode or
turned off. (The lights turn off immediately if on the key is pressed after all the doors
are locked.)
●When only the tail lights come on: The tail lights turn off automatically if the power
switch is turned to ACCESSORY mode or turned off and the driver’s door is opened.
To turn the lights on again, turn the power switch to ON mode, or turn the light switch off
once and then back to or .
■Automatic headlight leveling system (if equipped)
The level of the headlights is automatically ad justed according to the number of passen-
gers and the loading condition of the vehicle to ensure that the headlights do not inter-
fere with other road users.
■Light reminder buzzer
A buzzer sounds when the power switch is turned off or turned to ACCESSORY mode
and the driver’s door is opened while the lights are turned on.
■12-volt battery-saving function
In order to prevent the 12-volt battery of the vehicle from discharging, if the headlights
and/or tail lights are on when the power switch is turned off the 12-volt battery saving
function will operate and automatically turn off all the lights after approximately 20 min-
utes. When the power switch is turned to ON mode, the 12-volt battery-saving function
will be disabled.
When any of the following are performed, the 12-volt battery-saving function is canceled
once and then reactivated. All the lights w ill turn off automatically 20 minutes after the
12-volt battery-saving function has been reactivated:
●When the headlight switch is operated
●When a door is opened or closed
The sensor may not function properly if an
object is placed on the sensor, or anything that
blocks the sensor is affixed to the windshield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.

■The Automatic High Beam can be operated when
The power switch is in ON mode.
■Camera sensor detection 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 signals, 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, the system may not be able to correctly detect the surrounding
brightness levels, and may flash or expose nearby pedestrians to the high beam. There-
fore, you should consider turning the high be ams on or off manually rather than relying
on the Automatic High Beam system.
• 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.

Driving
NX300h_OM_USA_OM78082U
This mode employs a radar sensor to detect the presence of vehicles up to
approximately 400 ft. (120 m) ahead, determines the current vehicle-to-vehicle
following distance, and operates to maintain a suitable following distance from
the vehicle ahead.
Note that vehicle-to-vehicle distance will close in when traveling on long downhill
slopes.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-to-vehicle dis-
tance can also be set by operating the vehicle-to-vehicle distance control.
Example of deceleration cruising
When a preceding vehicle is driving slower than the set speed appears
When a vehicle is detected running ahead of you, the system automatically deceler-
ates your vehicle. When a greater reduction in vehicle speed is necessary, the system
applies the brakes (the stop lights will come on at this time). A warning tone warns you
when the system cannot decelera te sufficiently to prevent your vehicle from closing in
on the vehicle ahead.
Example of follow-up cruising
When following a preceding vehicle is driving slower than the set speed
The system continues follow-up cruising wh ile adjusting for changes in the speed of
the vehicle ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Example of acceleration
When there are no longer any preceding vehicles driving slower than the set
speed
The system accelerates until the set speed is reached. The system then returns to con-
stant speed cruising.
