WARNING
■Cautions regarding the use of the sys-
tem
The driver is solely responsible for safe
driving. Always driv e safely, taking care
to observe your surroundings.
The Rear Cross Traffic Alert function is
only an assist and is not a replacement for
careful driving. Driver must be careful
when backing up, even when using Rear
Cross Traffic Alert function. The driver’s
own visual confirmation of behind you
and your vehicle is necessary and be sure
there are no pedestrians, other vehicles,
etc., before backing up. Failure to do so
could cause death or serious injury.
According to conditions, the system may
not function correctly. Therefore the
driver’s own visual confirmation of safety
is necessary.

Helps to maintain directional stability
when swerving on slippery road sur-
faces by controlling steering perfor-
mance.
■Trailer Sway Control
Helps the driver to control trailer sway
by selectively applying brake pressure
for individual wheels and reducing
driving torque when trailer sway is
detected.
■TRAC (Traction Control)
Helps to maintain drive power and pre-
vent the drive wheels from spinning
when starting the vehicle or accelerat-
ing on slippery roads
■Hill-start assist control
Helps to reduce the backward move-
ment of the vehicle when starting on an
uphill
■EPS (Electric Power Steering)
Employs an electric motor to reduce
the amount of effort needed to turn the
steering wheel
■E-Four
Electronic On-Demand AWD system.
Automatically switches from front-
wheel drive to all-wheel drive (AWD)
according to the driving conditions,
helping to ensure reliable handling and
stability. Examples of conditions where
the system will switch to AWD are
when cornering, goin g uphill, starting
off or accelerating, and when the road
surface is slippery due to snow, rain,
etc.

■When the TRAC/VSC/ABS/Trailer
Sway Control systems are operating
The slip indicator light will flash while the
TRAC/VSC/ABS/Trailer Sway Control
systems are operating.
■Disabling the TRAC system
If the vehicle gets stuck in mud, dirt or snow,
the TRAC system may reduce power from
the hybrid system to the wheels. Pressing to turn the system off may make it eas-
ier for you to rock the vehicle in order to
free it.
To turn the TRAC system off, quickly press
and release .

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.

3847-2. Steps to take in an emergency
LEXUS NX300h Owners Manu-
al_USA_M78287_en
1Remove any dirt or foreign matter
from the wheel contact surface.
If foreign matter is on the wheel contact
surface, the wheel nuts may loosen while
the vehicle is in motion, causing the tire to come off.
2
Install the spare tire and loosely
tighten each wheel nut by hand by
approximately the same amount.
Tighten the wheel nuts until the tapered
portion comes into loose contact with
the disc wheel seat .
3Install the wheel nut wrench in jack
handle.
WARNING
●Failure to follow these precautions
could cause the wheel nuts to loosen
and the tire to fall of f, resulting in death
or serious injury.
• Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel
nuts to be excessively tightened, lead-
ing to bolt or disc wheel damage. In
addition, the oil or grease can cause
the wheel nuts to loosen and the wheel
may fall off, causing a serious accident.
Remove any oil or grease from the
wheel bolts or wheel nuts.
• Have the wheel nuts tightened with a torque wrench to 76 ft•lbf (103 N•m,
10.5 kgf•m) as soon as possible after
changing wheels.
• When installing a tire, only use wheel nuts that have been specifically
designed for that wheel.
• If there are any cracks or deformations in the bolt screws, nut threads or bolt
holes of the wheel, have the vehicle
inspected by your Lexus dealer.
• Do not attach a heavily damaged wheel ornament, as it may fly off the
wheel while the vehicle is moving.
■Replacing a flat tire for vehicles with
power back door
In cases such as when replacing tires,
make sure to turn off the power back
door main switch ( P.117). Failure to do
so may cause the back door to operate
unintentionally if the power back door
switch is accidentally touched, resulting
in hands and fingers being caught and
injured.

■The compact spare tire
●The compact spare tire is identified by the
label “TEMPORARY USE ONLY” on
the tire sidewall.
Use the compact spare tire temporarily,
and only in an emergency.
●Make sure to check the tire inflation pres-
sure of the compact spare tire. ( P.408)
■After completing the tire change
The tire pressure warning system must be
reset. ( P.343)
■When using the compact spare tire
As the compact spare tire is not equipped
with a tire pressure warning valve and trans-
mitter, low inflation pressure of the spare
tire will not be indicated by the tire pressure warning system. Also, if you replace the
compact spare tire afte
r the tire pressure
warning light comes on, the light remains
on.
■When the compact spare tire is
equipped
The vehicle becomes lower when driving
with the compact spare tire compared to
when driving with standard tires.
■If you have a flat front tire on a road cov-
ered with snow or ice
Install the compact spare tire on one of the
rear wheels of the vehicle. Perform the fol-
lowing steps and fit tire chains to the front
tires:
1 Replace a rear tire with the compact
spare tire.
2 Replace the flat front tire with the tire
removed from the rear of the vehicle.
3 Fit tire chains to the front tires.
WARNING
■When using the compact spare tire
●Remember that the sp are tire provided
is specifically designed for use with
your vehicle. Do not use your spare
tire on another vehicle.
●Do not use more than one spare tire
simultaneously.
●Replace the spare tire with a standard
tire as soon as possible.
●Avoid sudden acceleration, abrupt
steering, sudden br aking and shifting
operations that cause sudden engine
braking.
