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

Driving procedure

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.

When encountering flooded roads
Do not drive on a road that has flooded
after heavy rain, etc. Doing so may cause
the following serious damage to the vehi-
cle: ●
Engine stalling●
Short in electrical components●
Engine damage caused by water
immersion
In the event that you drive on a flooded
road and the vehicle is flooded, be sure
to have your Lexus dealer check the fol-
lowing: ●
Brake function●

 Instability happens more frequently
when descending steep or long
downhill grades. Before descend-
ing, slow down and downshift. Do
not make sudden downshifts while
descending steep or long downhill
grades.
 Avoid holding the brake pedal down
too long or applying the brakes too
frequently. This could cause the
brakes to overheat and result in
reduced braking efficiency.
 Due to the added load of the trailer,
your vehicle’s engine may overheat
on hot days (at temperatures over
85°F [30°C]) when driving up a
long or steep grade. If the engine
coolant temperature gauge indi-
cates overheating, immediately turn
off the air conditioning (if in use),
pull your vehicle off the road and
stop in a safe spot. ( → P.394)
 Always place wheel blocks under
both the vehicle’s and the trailer’s
wheels when parking. Put the trans-
mission in P and apply the parking
brake. Avoid parking on a slope, but
if unavoidable, do so only after per-
forming the following:
1 Apply the brakes and keep them
applied.
2 Have someone place wheel blocks
under both the vehicle’s and trailer’s
wheels. 3 When the wheel blocks are in
place, release the brakes slowly
until the blocks absorb the load.
4 Shift into P and apply the parking
brake.
5 Turn off the hybrid system.
 When restarting after parking on a
slope:
1 With the transmission in P, start the
hybrid system. Be sure to keep the
brake pedal depressed.
2 Shift into a forward gear. If revers-
ing, shift into R.
3 If the parking brake is in manual
mode, release the parking brake.
