1With the headlights on, push the
lever away from you to turn on the
high beams.
Pull the lever toward you to the center
position to turn the high beams off.
2Pull the lever toward you and
release it to flash the high beams

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
movement 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
■Cornering light control
●However, when vehicle speed is 25 mph
(40 km/h) or above, the cornering lights
do not turn on.
●After the lights remain illuminated for 30
minutes, they automatically turn off.
AFS (Adaptive Front-lighting System)
secures excellent visibility at intersec-
tions and on curves by automatically
adjusting the direction of the light axis
of the headlights according to vehicle
speed and the degree of the tire’s angle
as controlled by steering input.
AFS operates at speeds of 6 mph (10
km/h) or higher.
NOTICE

2024-5. Using the driving support systems
LEXUS NX300 Owners Manual_USA_M78389_en
■Operational conditions
The pre-collision system is enabled and the system determines that the possibility of a frontal
collision with a detect ed object is high.
Each function is operational at the following speed
●Pre-collision warning
●Pre-collision brake assist
●Pre-collision braking
The system may not operate in the following situations:
●If a battery terminal has been disconnected and reconnected and then the vehicle has not
been driven for a certain amount of time
●If the shift lever is in R
●When the VSC OFF indicator is illuminated (only the pre-collision warning function will
be operational)
■Object detection function
The system detects ob jects based on their
size, profile, motion, etc. However, an object
may not be detected depending on the sur-
rounding brightness and the motion, pos-
ture, and angle of the detected object,
preventing the system from operating prop- erly. (
P.204) The illustration shows an
image of detectable objects.

Driving
• The vehicle is driven on a gravel road or
in an area with tall grass
• Ice, snow, dirt, etc., has adhered to the sensor (if removed, the system returns to
normal)
• Heavy rain or water strikes the vehicle
• In severe weather such as fog, snow or a sand storm
●Influence from other sonic waves
• An ultrasonic wave source is nearby, such
as the horn or clearance sonar of another
vehicle, a vehicle detector, a motorcycle
engine or the air brake of a large vehicle
• Electronic components (such as a backlit license plate (especially fluorescent
types), fog lights, a fender pole or a wire-
less antenna) are installed near the sen-
sors
●Changes in the vehicle
• The vehicle is tilted a large amount
• The height of the vehicle has drastically changed due to the carried load (the
nose tilts up or down)
• The direction of the sensor has deviated
due to a collision or other impact
■When “Parking Support Brake Unavail-
able” is displayed on the multi-informa-
tion display and the PKSB OFF indicator
flashes
●Ice, snow, dirt, etc., may have adhered to
the sensor. If this occurs, remove the ice,
snow, dirt, etc., from the sensor to return
the system to normal. Also, a warning message may be dis-
played at low temperatures due to ice
forming on the sensor, and the sensor
may not detect static objects. Once the
ice melts, the system will return to normal.
●If this message is
shown even after
removing dirt from the sensor, or shown
when the sensor was not dirty to begin
with, have the vehicle inspected by your
Lexus dealer.
●System initialization may not have been
performed after remova l and installation
of the battery. Perform system initializa-
tion.
■When removing and installing the bat-
tery
The system needs to be initialized.
The system can be initialized by driving the
vehicle straight ahead for 5 seconds or
more at a speed of approximately 22 mph
(35 km/h) or higher.
■When “Parking Support Brake Mal-
function Visit Your Dealer” is displayed
on the multi-information display, the
PKSB OFF indicator flashes and the
buzzer sounds
The system may not be operating properly.
Have the vehicle inspected by your Lexus
dealer.
WARNING
■In order for the system to operate
properly
Make sure to observe the following pre-
cautions regarding the sensors
(  P.239). Failure to observe these pre-
cautions may cause the sensors not to
operate properly, and may result in an
unexpected accident.
●Do not perform work such as modifi-
cation, disassembly or painting
●Only perform replacements using
genuine parts
●Do not subject the area around the
sensors to any impacts

4-6.Driving tips
Use fluids that are appropriate to
the prevailing outside temperatures.
• Engine oil
• Engine coolant
• Washer fluid
Have a service technician inspect
the condition of the battery.
 Have the vehicle fitted with four
snow tires or purchase a set of tire
chains for the front tires
*.
Ensure that all tires are the same size and
brand, and that chains match the size of the
tires.
*: Tire chains cannot be mounted on the
225/60R18 tires.
Snow tires should be used instead.
Perform the following according to the
Winter driving tips
Carry out the necessary prepara-
tions and inspections before driving
the vehicle in winter. Always drive
the vehicle in a manner appropriate
to the prevailing weather condi-
tions.
Preparation for winter
WARNING
■Driving with snow tires
Observe the following precautions to
reduce the risk of accidents.
Failure to do so may result in a loss of
vehicle control and cause death or seri-
ous injury.
●Use tires of the specified size.
●Maintain the recommended level of air
pressure.
●Do not drive in excess of 75 mph (120
km/h), regardless of the type of snow
tires being used.
●Use snow tires on all, not just some
wheels.
■Driving with tire chains
Observe the following precautions to
reduce the risk of accidents.
Failure to do so may result in the vehicle
being unable to be driven safely, and may
cause death or serious injury.
●Do not drive in excess of the speed
limit specified for the tire chains being
used, or 30 mph (50 km/h), which-
ever is lower.
●Avoid driving on bumpy road surfaces
or over potholes.
●Avoid sudden acceleration, abrupt
steering, sudden br aking and shifting
operations that cause sudden engine
braking.
●Slow down sufficiently before entering
a curve to ensure that vehicle control is
maintained.
●Do not use LDA (Lane Departure
Alert with steering control) (if
equipped).
●Do not use LTA (Lane Tracing Assist)
(if equipped).
NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow
tires from Lexus dealers or legitimate tire
retailers.
This is because the removal and attach-
ment of snow tires affects the operation
of the tire pressure warning valves and
transmitters.

■When the outside temperature is low
The dehumidification function may not
operate even when “A/C” is pressed or
“A/C” is selected.
■Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning
system to the outside air mode.
●During use, various odors from inside and
outside the vehicle may enter into and
accumulate in the air conditioning sys-
tem. This may then cause odor to be
emitted from the vents.
●To reduce potential odors from occur-
ring:
• It is recommended that the air condition-
ing system be set to outside air mode
prior to turning the vehicle off.
• The start timing of the blower may be
delayed for a short period of time imme-
diately after the air conditioning system is
started in automatic mode.

WARNING
■To prevent the windshield from fog-
ging up
●Do not use the front windshield defog-
ger switch during cool air operation in
extremely humid weather. The differ-
ence between the temperature of the
outside air and that of the windshield
can cause the outer surface of the
windshield to fog up, blocking your
vision.
■To prevent burns
●Do not touch the rear view mirror sur-
faces when the outside rear view mir-
ror defoggers are on.
●Vehicles with windshield wiper de-
icer: Do not touch the glass at lower
part of the windshield or to the side of
the front pillars when the windshield
wiper de-icer is on.
