LEXUS NX300h Owners Manu-
al_USA_OM78212U WARNING●
During normal driving, do not turn off
the hybrid system. Turning the hybrid
system off while driving will not cause
loss of steering or braking control,
however, power assist to the steering
will be lost. This will make it more diffi-
cult to steer smoothly, so you should
pull over and stop the vehicle as soon
as it is safe to do so.
In the event of an emergency, such as if
it becomes impossible to stop the vehi-
cle in the normal way: → P.358●
Use engine braking (downshift) to
maintain a safe speed when driving
down a steep hill.
Using the brakes continuously may
cause the brakes to overheat and lose
effectiveness. ( → P.176)●
Do not adjust the positions of the
steering wheel, the seat, or the inside
or outside rear view mirrors while driv-
ing.
Doing so may result in a loss of vehicle
control.●
Always check that all passengers’
arms, heads or other parts of their
body are not outside the vehicle.●
Do not drive the vehicle off-road.
This is not an AWD vehicle designed
for off-road driving. Proceed with all
due caution if it becomes unavoidable
to drive off-road.
●
Do not drive across a river or through
other bodies of water.
This may cause electric/electronic
components to shor t circuit, damage
the hybrid system or cause other seri-
ous damage to the vehicle. ●
Do not drive in excess of the speed
limit. Even if the legal speed limit per-
mits it, do not drive over 85 mph (140
km/h) unless your vehicle has high-
speed capability tires.
Driving over 85 mph (140 km/h) may
result in tire failur e, loss of control and
possible injury. Be sure to consult a tire
dealer to determine whether the tires
on your vehicle are high-speed capa-
bility tires or not befo re driving at such
speeds. ■
When driving on slippery road sur-
faces ●
Sudden braking, acceleration and
steering may cause tire slippage and
reduce your ability to control the vehi-
cle. ●
Sudden acceleration, engine braking
due to shifting, or changes in engine
speed could cause the vehicle to skid. ●
After driving through a puddle, lightly
depress the brake pedal to make sure
that the brakes are functioning prop-
erly. Wet brake pads may prevent the
brakes from functioning properly. If the
brakes on only one side are wet and
not functioning properly, steering con-
trol may be affected.
■
When shifting the shift lever ●
Do not let the vehicle roll backward
while the shift lever is in a driving posi-
tion, or roll forward while the shift lever
is in R.
Doing so may result in an accident or
damage to the vehicle.
●
Do not shift the shif t lever to P while
the vehicle is moving.
Doing so can damage the transmission
and may result in a loss of vehicle con-
trol.
●
Do not shift the shift lever to R while
the vehicle is moving forward.
Doing so can damage the transmission
and may result in a loss of vehicle con-
trol.

Contact your Lexus dealer for further
information about additional require-
ments such as a towing kit, etc. ■
Matching trailer ball height to trailer
coupler height
No matter which class of tow hitch applies,
for a more safe trailer hookup, the trailer
ball setup must be the proper height for the
coupler on the trailer. Coupler
Trailer ball ■
Before towing
Check that the following conditions are
met: ●
Ensure that your vehicle’s tires are prop-
erly inflated. ( → P.406)●
Trailer tires are inflated according to the
trailer manufacturer’s recommendation. ●
All trailer lights work as required by law. ●
All lights work each time you connect
them. ●
The trailer ball is set at the proper height
for the coupler on the trailer. ●
The trailer is level when it is hitched.
Do not drive if the trailer is not level, and
check for improper tongue weight, over-
loading, worn suspension, or other possi-
ble causes.
●
The trailer cargo is securely loaded.
●
The rear view mirrors conform to all
applicable federal, state/provincial or
local regulations. If they do not, install
rear view mirrors appropriate for towing
purposes.

Break-in schedule
If your vehicle is new or equipped with any
new power train components (such as an
engine, transmission, di fferential or wheel
bearing), Lexus recommends that you do
not tow a trailer until the vehicle has been Trailer towing (vehicles with
towing package) Your vehicle is de signed primarily
as a passenger-and-load-carrying
vehicle. Towing a trailer can have an
adverse impact on handling, per-
formance, braking, durability, and
fuel consumption. For your safety
and the safety of others, you must
not overload your vehicle or trailer.
You must also ensure that you are
using appropriate towing equip-
ment, that the towing equipment
has been installed correctly and
used properly, and that you employ
the requisite driving habits.
Vehicle-trailer stability and braking
performance are affected by trailer
stability, brake performance and
setting, trailer brakes, the hitch and
hitch systems (if equipped).
To tow a trailer safely, use extreme
care and drive the vehicle in accor-
dance with your trailer’s character-
istics and operating conditions.
Lexus warranties do not apply to
damage or malfunction caused by
towing a trailer for commercial pur-
poses. A

High beam may be turned on or off when
unexpected by the driver.●
In the situations below, the system may
not be able to correctly detect the sur-
rounding brightness levels, and may flash
or expose nearby pedestrians to the high
beam. Therefore, you should consider
turning the high beams on or off manually
rather than relying on the Automatic
High Beam system.
• In bad weather (rain, snow, fog, sand-
storms, etc.)
• The windshield is obscured by fog, mist,
ice, dirt, etc.
• The windshield is cracked or damaged.
• The camera sensor is deformed or dirty.
• The camera sensor temperature is
extremely high.
• Surrounding brightness levels are equal
to those of headlights, tail lights or fog
lights.
• Vehicles ahead have headlights or tail
lights that are either switched off, dirty,
are changing color, or are not aimed
properly.
• When driving through an area of inter-
mittently changing brightness and dark-
ness.
• When frequently and repeatedly driving
ascending/descending roads, or roads
with rough, bumpy or uneven surfaces
(such as stone-paved roads, gravel
tracks, etc.).
• When frequently and repeatedly taking
curves or driving on a winding road.
• There is a highly re flective object ahead
of the vehicle, such as a sign or a mirror.
• The back of a vehicle ahead is highly
reflective, such as a container on a truck.
• The vehicle’s headlights are damaged or
dirty. • The vehicle is listing or titling, due to a flat
tire, a trailer being towed, etc.
• The driver believes that the high beam
may be causing problems or distress to
other drivers or pedestrians nearby.
