Driving
Assists acceleration response by con-
trolling the hybrid system and steering.
Suitable for when precise handling is desir-
able, for example when driving on moun-
tain roads.
When not in Sport mode and the driving
mode select switch is turned to the right,
“Sport” indicator will be shown on the
multi-information display and the hybrid
system indicator changes to the tachome-
ter. ( P.79)
■Operation of the air conditioning sys-
tem in Eco mode
Eco mode controls the heating/cooling
operations and fan speed of the air condi-
tioning system to enhance fuel efficiency. To
improve air conditio ning performance,
adjust the fan speed or turn off Eco mode.
■When canceling Eco mode/Sport mode
●Select another driving mode. Also, Sport
mode will be canceled automatically
when the power switch is turned off.
●Normal mode and Eco mode will not be
canceled automatically until another driv-
ing mode is selected, even if the power
switch is turned off.
■ECB (Electronically Controlled
Brake System)
The electronically controlled system
generates braking force correspond-
ing to the brake operation
■ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the
brakes are applied suddenly, or if the
brakes are applied while driving on a
slippery road surface
■Brake assist
Generates an increased level of brak-
ing force after the brake pedal is
depressed when the system detects a
panic stop situation
■VSC (Vehicle Stability Control)
Helps the driver to control skidding
when swerving sudden ly or turning on
slippery road surfaces
■Enhanced VSC (Enhanced Vehi-
cle Stability Control)
Provides cooperative control of the
ABS, TRAC, VSC and EPS.
Driving assist systems
To keep driving safety and perfor-
mance, the following systems oper-
ate automatically in response to
various driving situations. Be aware,
however, that these systems are
supplementary and should not be
relied upon too heavily when oper-
ating the vehicle.
Summary of the driving assist
systems

2524-5. Using the driving support systems
LEXUS NX300h Owners Manu-
al_USA_M78287_enTRAC will turn on when vehicle speed
increases
●If only the TRAC system is turned off, the
TRAC will turn on when vehicle speed
increases
If both the TRAC and VSC systems are
turned off, automatic re-enabling will not
occur when vehicle speed increases.
■Operating conditions of hill-start assist
control
When the following four conditions are met,
the hill-start assist control will operate:
●The shift lever is in a position other than P
or N (when starting off forward/back-
ward on an upward incline).
●The vehicle is stopped.
●The accelerator pedal is not depressed.
●The parking brake is not engaged.
■Automatic system cancelation of hill-
start assist control
The hill-start assist control will turn off in any
of the following situations:
●The shift lever is shifted to P or N.
●The accelerator pedal is depressed.
●The parking brake is engaged.
●2 seconds at maximum elapsed after the
brake pedal is released
WARNING
■The ABS does not operate effectively
when
●The limits of tire gripping performance
have been exceeded (such as exces-
sively worn tires on a snow covered
road).
●The vehicle hydroplanes while driving
at high speed on wet or slick road.
■Stopping distance when the ABS is
operating may exceed that of normal
conditions
The ABS is not designed to shorten the
vehicle’s stopping di stance. Always main-
tain a safe distance from the vehicle in
front of you, especially in the following
situations:
●When driving on dirt, gravel or snow-
covered roads
●When driving with tire chains
●When driving over bumps in the road
●When driving over roads with potholes
or uneven surfaces
■TRAC/VSC may not operate effec-
tively when
Directional control and power may not
be achievable while driving on slippery
road surfaces, even if the TRAC/VSC
system is operating.
Drive the vehicle carefully in conditions
where stability and po wer may be lost.
■Hill-start assist control does not oper-
ate effectively when
●Do not overly rely on the hill-start
assist control. Hill-start assist control
may not operate effectively on steep
inclines and roads covered with ice.
●Unlike the parking brake, hill-start
assist control is not intended to hold
the vehicle stationary for an extended
period of time. Do not attempt to use
hill-start assist control to hold the vehi-
cle on an incline, as doing so may lead
to an accident.
■When the TRAC/ABS/VSC/Trailer
Sway Control is activated
The slip indicator light flashes. Always
drive carefully. Reckless driving may
cause an accident. Exercise particular
care when the indicator light flashes.

Driving
WARNING
■When the TRAC/VSC/Trailer Sway
Control systems are turned off
Be especially careful and drive at a speed
appropriate to the road conditions. As
these are the system s to help ensure
vehicle stability and driving force, do not
turn the TRAC/VSC/Trailer Sway Con-
trol systems off unless necessary.
Trailer Sway Control is part of the VSC
system and will not operate if VSC is
turned off or experiences a malfunction.
■Replacing tires
Make sure that all ti res are of the speci-
fied size, brand, tread pattern and total
load capacity. In addition, make sure that
the tires are inflated to the recom-
mended tire inflation pressure level.
The ABS, TRAC, Trailer Sway Control
and VSC systems will not function cor-
rectly if different tire s are installed on the
vehicle.
Contact your Lexus dealer for further
information when replacing tires or
wheels.
■Handling of tires and the suspension
Using tires with any kind of problem or
modifying the suspension will affect the
driving assist systems, and may cause a
system to malfunction.
■Trailer Sway Control precaution
The Trailer Sway Control system is not
able to reduce trailer sway in all situa-
tions. Depending on many factors such
as the conditions of the vehicle, trailer,
road surface and driving environment,
the Trailer Sway Control system may not
be effective. Refer to your trailer owner’s
manual for information on how to tow
your trailer properly.
■If trailer sway occurs
Observe the following precautions.
Failing to do so may cause death or seri-
ous injury.
●Firmly grip the steering wheel. Steer
straight ahead. Do not try to control
trailer sway by turning the steering
wheel.
●Begin releasing the accelerator pedal
immediately but very gradually to
reduce speed.
Do not increase speed. Do not apply
vehicle brakes.
If you make no extreme correction with
the steering or brakes, your vehicle and
trailer should stabilize. ( P.250)

4-6.Driving tips
When using Eco mode, the torque cor-
responding to the accelerator pedal
depression amount can be generated
more smoothly than it is in normal con-
ditions. In addition, the operation of the
air conditioning system (heating/cool-
ing) will be minimized, improving the
fuel economy. (P.248)
The Eco-friendly driving is possible by
keeping the indicator needle of Hybrid
System Indicator within Eco area.
(  P.82)
Shift the shift lever to D when stopped
at a traffic light, or driving in heavy traf-
fic, etc. Shift the shift lever to P when
parking. When using the N, there is no
positive effect on fuel consumption. In
the N, the gasoline engine operates
but electricity cannot be generated.
Also, when using the air conditioning
system, etc., the hybrid battery (trac-
tion battery) power is consumed. 
Drive your vehicle smoothly. Avoid
abrupt acceleration and decelera-
tion. Gradual acceleration and
deceleration will make more effec-
tive use of the electric motor (trac-
tion motor) without having to use
gasoline engine power.
 Avoid repeated acceleration.
Repeated acceleration consumes
hybrid battery (traction battery)
power, resulting in poor fuel con-
sumption. Battery power can be
restored by driving with the acceler-
ator pedal slightly released.
Make sure to operate the brakes gently
and in a timely manner. A greater
amount of electrical energy can be
regenerated when slowing down.
Repeated acceleration and decelera-
tion, as well as long waits at traffic
lights, will lead to bad fuel economy.
Check traffic reports before leaving
and avoid delays as much as possible.
When driving in a traffic jam, gently
release the brake pedal to allow the
vehicle to move forward slightly while
avoiding overuse of the accelerator
pedal. Doing so can help control
excessive gasoline consumption.

Driving
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
restrict travel.
 Stay on established roads. When
conditions are wet, driving tech-
niques should be changed or travel
delayed to prevent damage to
roads.
 Avoid driving on very steep, slippery
roads and other surfaces, such as
sand, where the tires are liable to
lose traction. Your vehicle may not
perform as well as conventional
AWD on-road vehicles on these
surfaces.
■Additional informatio n for off-road driv-
ing
For owners in U.S. mainland, Hawaii and
Puerto Rico:
To obtain additional information pertaining
to driving your vehicle off-road, consult the
following organizations.
●State and Local Parks and Recreation
Departments
●State Motor Vehicle Bureau
●Recreational Vehicle Clubs
●U.S. Forest Service and Bureau of Land
Management
WARNING
●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, sudden 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 straig ht 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.
Off-road driving
WARNING
■Off-road driving precautions
Always observe the following precau-
tions to minimize the risk of death or seri-
ous injury or damage to your vehicle:
●Drive carefully when off the road. Do
not take unnecessary risks by driving in
dangerous places.
●Do not grip the steering wheel spokes
when driving off-road. A bad bump
could jerk the wheel and injure your
hands. Keep both hands and especially
your thumbs on the outside of the rim.
