For fuel-efficient driving
Keep in mind that hybr id vehicles are similar
to conventional vehicles, and it is necessary
to refrain from activi ties such as sudden
acceleration. ( → P.255)■
Driving in the rain ●
Drive carefully when it is raining, because
visibility will be reduced, the windows
may become fogged-up, and the road
will be slippery. ●
Drive carefully when it starts to rain,
because the road surface will be espe-
cially slippery.
●
Refrain from high speeds when driving on
an expressway in the rain, because there
may be a layer of wa ter between the tires
and the road surface, preventing the
steering and brakes from operating prop-
erly.
■
Restraining the hybrid system output
(Brake Override System)
●
When the accelerato r and brake pedals
are depressed at the same time, the
hybrid system output may be restrained.
●
A warning message is displayed on the Driving the vehicle The specified procedures should be
observed to ensure safe driving:
Driving procedure

152 4-1. Before driving
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.

154 4-1. Before driving
LEXUS NX300h Owners Manu-
al_USA_OM78212U WARNING●
Always apply the parking brake, shift
the shift lever to P, stop the hybrid sys-
tem and lock the vehicle.
Do not leave the vehicle unattended
while the “READY” indicator is illumi-
nated.
If the vehicle is parked with the shift
lever in P but the parking brake is not
set, the vehicle may start to move, pos-
sibly leading to an accident.●
Do not touch the exhaust pipes while
the “READY” indicator is illuminated
or immediately after turning the hybrid
system off.
Doing so may cause burns.■
When taking a nap in the vehicle
Always turn the hybrid system off. Other-
wise, if you accidentally move the shift
lever or depress the accelerator pedal,
this could cause an accident or fire due
to hybrid system overheating. Addition-
ally, if the vehicle is parked in a poorly
ventilated area, exha ust gases may col-
lect and enter the ve hicle, leading to
death or a serious health hazard. ■
When braking●
When the brakes are wet, drive more
cautiously.
Braking distance increases when the
brakes are wet, and this may cause one
side of the vehicle to brake differently
than the other side. Also, the parking
brake may not securely hold the vehi-
cle.
●
If the electronically controlled brake
system does not operate, do not follow
other vehicles closely and avoid hills or
sharp turns that require braking.
In this case, braking is still possible, but
the brake pedal should be depressed
more firmly than usual. Also, the brak-
ing distance will increase. Have your
brakes fixed immediately. ●
The brake system consists of 2 or more
individual hydraulic systems; if one of
the systems fails, the other(s) will still
operate. In this case, the brake pedal
should be depressed more firmly than
usual and the braking distance will
increase. Have your brakes fixed
immediately. ■
If the vehicle becomes stuck
Do not spin the wheels excessively when
any of the tires is up in the air, or the vehi-
cle is stuck in sand, mud, etc. This may
damage the driveline components or
propel the vehicle forward or backward,
causing an accident.
NOTICE■
When driving the vehicle ●
Do not depress the accelerator and
brake pedals at the same time during
driving, as this may restrain the hybrid
system output. ●
Do not use the accelerator pedal or
depress the accelerator and brake
pedals at the same time to hold the
vehicle on a hill. ■
Avoiding damage to vehicle parts ●
Do not turn the steering wheel fully in
either direction and hold it there for an
extended period of time.
Doing so may damage the power
steering motor.
●
When driving over bumps in the road,
drive as slowly as possible to avoid
damaging the wheels, underside of the
vehicle, etc.
■
If you get a flat tire while driving
A flat or damaged tire may cause the fol-
lowing situations. Hold the steering
wheel firmly and gradually depress the
brake pedal to slow down the vehicle.
●
It may be difficult to control your vehi-
cle.
