mode (the engine is not running) for more than an hour with the shift lever in P, the engine
switch will automatically turn off. However, this function cannot entirely prevent battery
discharge. Do not leave the vehicle with the engine switch in ACCESSORY or IGNI-
TION ON mode for long periods of ti me when the engine is not running.

will be locked due to the stee ring lock function. Operating the engine switch again auto-
matically cancels the steering lock.
■When the steering lock cannot be released
■Steering lock motor overheating prevention
To prevent the steering lock motor from over heating, operation of the motor may be sus-
pended if the engine is turned on and off repeat edly in a short period of time. In this case,
refrain from running the engine. After about 10 seconds, the steering lock motor will
resume functioning.

■Operation of the engine switch
●When operating the engine switch, one short, firm press is enough. If the switch is
pressed improperly, the engine may not start or the engine switch mode may not
change. It is not necessary to press and hold the switch.
●If attempting to restart the engine immediat ely after turning the engine switch off, the
engine may not start in some cases. After tu rning the engine switch off, please wait a
few seconds before re starting the engine.

■When starting the engine
Always start the engine while sitting in the driver’s seat. Do not depress the accelerator
pedal while starting the engine under any circumstances.
Doing so may cause an accident resu lting in death or serious injury.
■Caution while driving
If engine failure occurs while the vehicle is moving, do not lock or open the doors until
the vehicle reaches a safe and complete stop. The steering lock function will activate
and this may lead to an accident, resulting in death or serious injury.
■Stopping the engine in an emergency
If you want to stop the engine in an emergency while driving the vehicle, press and hold
the engine switch for more than 2 seconds, or press it briefly 3 times or more in succes-
sion. ( P. 5 4 1 )
However, do not touch the engine switch while driving except in an emergency. Turning
the engine off while driving will not cause lo ss of steering or braking control, however,
power assist to the steering will be lost. This will make it more difficult to steer smoothly,
so you should pull over and stop the vehi cle as soon as it is safe to do so.

2124-3. Operating the lights and wipers
NX200t_OM_USA_OM78081U
When the following conditions are met, while the headlights (low beam) are on,
the cornering lights will additionally turn on and light up the direction of move-
ment for the vehicle. This is to ensure excellent visibility when either driving at
intersections or parking at night.
●The steering wheel is operated
●The turn signal lever is operated
●The shift lever is in R
However, when vehicle speed is 40 km/h (25 mph) or above, the cornering
lights do not turn on.
When the cornering lights ar e on for more than 30 minutes, they will automati-
cally turn off.
■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 increased intensity) whenever the engine is
started and the parking brake is released 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 engine 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 engine
switch is turned to ACCESSORY mode or turned off and the driver’s door is opened.
To turn the lights on again, turn the engine switch to IGNITION ON mode, or turn the
light switch off once and then back to or .
Cornering lights (if equipped)
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.

■Conditions under which the vehicle-to-vehic le distance control mode may not func-
tion correctly
Operate the brake pedal (or accelerator pe dal operation depending on the situation)
as necessary in the following conditions as the radar sensor may not be able to cor-
rectly detect vehicles ahead, which may lead to an accident resulting in death or seri-
ous injury.
●When the vehicle ahead of you decelerates suddenly
●When your vehicle is pointing upwards
(caused by a heavy load in the luggage com-
partment, etc.)
●When the road curves or when the lanes are
narrow
●When steering wheel operation or your posi-
tion in the lane is unstable

LDA (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.

◆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.
