ground clearance
• If a vehicle ahead is carrying a load which protrudes past its rear bumper
• If a vehicle ahead is irregularly shaped, such as a tractor or side car
• If a vehicle ahead is a child sized bicycle, a bicycle that is carrying a large load, a
bicycle ridden by more than one person,
or a uniquely shaped bicycle (bicycle with
a child seat, tandem bicycle, etc.)
• If a pedestrian/or the riding height of a
bicyclist ahead is shorter than approxi-
mately 3.2 ft. (1 m) or taller than approxi-
mately 6.5 ft. (2 m)
• If a pedestrian/bicyclist is wearing over- sized clothing (a rain coat, long skirt,
etc.), making their silhouette obscure
• If a pedestrian is bending forward or squatting or bicyclist is bending forward
• If a pedestrian/bicyclist is moving fast
• If a pedestrian is pushing a stroller, wheel-
chair, bicycle or other vehicle
• When driving in incl ement weather such
as heavy rain, fog, snow or a sandstorm
• When driving through steam or smoke
• When the surrounding area is dim, such as at dawn or dusk, or while at night or in
a tunnel, making a detectable object
appear to be nearly the same color as its
surroundings
• When driving in a place where the sur- rounding brightness changes suddenly,
such as at the entrance or exit of a tunnel
• After the engine has started the vehicle has not been driven for a certain amount
of time
• While making a left/right turn and for a few seconds after makin g a left/right turn
• While driving on a curve and for a few
seconds after driving on a curve
• If your vehicle is skidding

• If a wiper blade is blocking the front cam-
era
• The vehicle is being driven at extremely high speeds
• When driving on a hill
• If the radar sensor or front camera is mis-
aligned
●In some situations su ch as the following,
sufficient braking force may not be
obtained, preventing the system from
performing properly:
• If the braking functions cannot operate to their full extent, such as when the brake
parts are extremely cold, extremely hot,
or wet
• If the vehicle is not properly maintained
(brakes or tires are excessively worn,
improper tire inflation pressure, etc.)
• When the vehicle is being driven on a
gravel road or other slippery surface
■If VSC is disabled
●If VSC is disabled ( P.261), the pre-col-
lision brake assist and pre-collision brak-
ing functions are also disabled.
●The PCS warning light will turn on and
“VSC Turned Off Pre-Collision Brake
System Unavailable” will be displayed on
the multi-information display.

lane
●Vehicles with small rear ends (trailers
with no load on board, etc.)
●Motorcycles travelin
g in the same lane
●When water or snow thrown up by the
surrounding vehicles hinders the detect-
ing of the sensor
●When your vehicle is pointing upwards
(caused by a heavy load in the luggage
compartment, etc.)
●Preceding vehicle has an extremely high
ground clearance
■Conditions under which the vehicle-to-
vehicle distance control mode may not
function correctly
In the case of the following conditions,
operate the brake pedal (or accelerator
pedal, depending on the situation) as nec-
essary.
As the sensor may not be able to correctly
detect vehicles ahead, the system may not
operate properly.
●When the road curves or when the lanes are narrow
●When steering wheel operation or your
position in the lane is unstable
●When the vehicle ahead of you deceler-
ates suddenly
●When driving on a road surrounded by a
structure, such as in a tunnel or on a
bridge
●While the vehicle speed is decreasing to
the set speed after the vehicle acceler-
ates by depressing the accelerator pedal

■Operation starting conditions
When the PKSB OFF indicator is not illumi-
nated or flashing ( P.242, 378) and all of
the following conditions are met, the system
operates.
●Engine output restriction control
• The Parking Support Brake function (for static objects) is on.
• The vehicle speed is 10 mph (15 km/h) or
less.
• There is a static ob ject in the traveling
direction of the vehicle (6 to 13 ft. [2 to 4
m] ahead).
• The system determined that a stronger than-normal brake operation was neces-
sary to avoid a collision.
●Brake control
•Engine output restrict ion control is being
performed.
• The system determined that an emer- gency brake operation was necessary to
avoid a collision.
■Operation ending conditions
In any of the following situations, the system
stops operating.
●Engine output restriction control
• The Parking Support Brake function (for static objects) ha s been turned off
(stopped).
• The collision became avoidable with nor- mal brake operation.
• The static object is no longer in the travel-
ing direction of the vehicle (6 to 13 ft. [2 to 4 m] ahead).
●Brake control
• The Parking Support Brake function (for static objects) has been turned off
(stopped).
• Approximately 2 seconds elapsed after the vehicle was stopped by brake control.
• The brake pedal was depressed after the
vehicle was stopped by brake control.
• The static object is no longer in the travel- ing direction of the vehicle (6 to 13 ft. [2
to 4 m] ahead).
■Sensor detection range
The detection range of the Parking Support
Brake function (for static objects) differs
from the detection range of the clearance
sonar ( P.239).
Therefore, even if the clearance sonar
detects a static object and provides a warn-
ing, the Parking Support Brake function (for
static objects) may not start operating.
■Static objects not detected by the sen-
sors
The following static objects may not be
detected by the sensors.
●Objects such as people, cloth and snow,
that are difficult for sonic waves to reflect
off of. (In particular, people may also not
be detected depending on the type of
clothing they are wearing.)
●Objects not perpendicular with the
ground, objects not at a right angle to the
traveling direction of the vehicle, uneven

Driving
Specific design characteristics give
it a higher center of gravity than
ordinary passenger cars. This vehi-
cle design feature causes this type
of vehicle to be more likely to roll-
over. Utility vehicles have a signifi-
cantly higher rollover rate than
other types of vehicles.
 An advantage of the higher ground
clearance is a better view of the
road allowing you to anticipate
problems.
 It is not designed for cornering at
the same speeds as ordinary pas-
senger cars anymore than low-slung
sports cars designed to perform sat-
isfactorily under of f-road conditions.
Therefore, sharp turns at excessive
speeds may cause rollover. Your vehicle is not designed to be
driven off-road. However, in the event
that off-road driving cannot be
avoided, please observe the following
precautions to help avoid the areas
prohibited to vehicles.

Drive your vehicle only in areas
where off-road vehicles are permit-
ted to travel.
 Respect private property. Get
owner’s permission before entering
private property.
 Do not enter areas that are closed.
Honor gates, barriers and signs that
Utility vehicle precautions
This vehicle belongs to the utility
vehicle class, which has higher
ground clearance and narrower
tread in relation to the height of its
center of gravity.
Utility vehicle feature
WARNING
■Utility vehicle precautions
Always observe the following precau-
tions to minimize the risk of death or seri-
ous injury or damage to your vehicle:
●In a rollover crash, an unbelted person
is significantly more likely to die than a
person wearing a seat belt. Therefore,
the driver and all passengers should
always fasten th eir seat belts.
●Avoid sharp turns or abrupt maneu-
vers, if at all possible.
Failure to operate this vehicle correctly
may result in loss of control or vehicle
rollover causing death or serious
injury.
●Loading cargo on the roof luggage
carrier (if equipped) will make the cen-
ter of the vehicle gravity higher. Avoid
high speeds, sudd en starts, sharp
turns, sudden braking or abrupt
maneuvers, otherwise it may result in
loss of control or vehicle rollover due
to failure to operate this vehicle cor-
rectly.
●Always slow down in gusty crosswinds.
Because of its profile and higher cen-
ter of gravity, your vehicle is more sen-
sitive to side winds than an ordinary
passenger car. Slowing down will allow
you to have better control.
●Do not drive horizontally across steep
slopes. Driving straight up or straight
down is preferred. Your vehicle (or any
similar off-road vehicle) can tip over
sideways much more easily than for-
ward or backward.

3707-2. Steps to take in an emergency
LEXUS NX300 Owners Manual_USA_M78389_en
The following may indicate a problem
with your transmission. Contact your
Lexus dealer or commercial towing
service before towing. (P.369)
 The engine is running but the vehi-
cle does not move.
 The vehicle makes an abnormal
sound.
Do not tow with a sling-type truck to
prevent body damage.
WARNING
●Do not turn the engine switch off.
There is a possibility that the steering
wheel is locked and cannot be oper-
ated.
■Installing towing eyelets to the vehi-
cle
Make sure that towing eyelets are
installed securely.
If not securely installed, towing eyelets
may come loose during towing.
NOTICE
■To prevent damage to the vehicle
when towing using a wheel-lift type
truck
●Do not tow the vehicle from the rear
when the engine switch is off.
The steering lock mechanism is not
strong enough to hold the front wheels
straight.
●When raising the vehicle, ensure ade-
quate ground clearance for towing at
the opposite end of the raised vehicle.
Without adequate clearance, the vehi-
cle could be damaged while being
towed.
■To prevent damage to the vehicle
when towing with a sling-type truck
Do not tow with a sling-type truck, either
from the front or rear.
■Recreational towing (behind motor
home, etc.)
Never dinghy tow your vehicle to pre-
vent causing serious damage to the
Dynamic Torque Control AWD system
(AWD models) and transmission.
