1484-1. Before driving
LEXUS NX300 Owners Manual_USA_M78389_en
WARNING
■When driving the vehicle
●Do not drive if you are unfamiliar with
the location of the brake and accelera-
tor pedals to avoid depressing the
wrong pedal.
• Accidentally depressing the accelera- tor pedal instead of the brake pedal
will result in sudden acceleration that
may lead to an accident.
• When backing up, you may twist your body around, leading to difficulty in
operating the pedals. Make sure to
operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the vehicle
only slightly. This allows you to depress
the brake and accelerator pedals
properly.
• Depress the brake pedal using your right foot. Depressing the brake pedal
using your left foot may delay
response in an emergency, resulting in
an accident.
●Do not drive the vehicle over or stop
the vehicle near flammable materials.
The exhaust system and exhaust gases
can be extremely hot. These hot parts
may cause a fire if there is any flamma-
ble material nearby.
●During normal driving, do not turn off
the engine. Turning the engine off
while driving will not cause loss of
steering or braking control, but the
power assist to these systems will be
lost. This will make it more difficult to
steer and brake, 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.366
●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.168)
●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.
●AWD models: 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 short circuit, damage
the engine or cause other serious
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 failure, 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.

Driving
WARNING
●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 cause the engine to stall
or lead to poor brake and steering
performance, resulting in an accident
or damage to the vehicle.
●Do not shift the shift 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.
●Do not shift the shift lever to a driving
position while the vehicle is moving
backward.
Doing so can damage the transmission
and may result in a loss of vehicle con-
trol.
●Shifting the shift lever to N while the
vehicle is moving will disengage the
engine.
Engine braking is not available when N
is selected.
●Be careful not to shift the shift lever
with the accelerator pedal depressed.
Shifting the shift lever to any position
other than P or N may lead to unex-
pected rapid acceleration of the vehi-
cle that may cause an accident and
result in death or serious injury.
■If you hear a squealing or scraping
noise (brake pad wear limit indica-
tors)
Have the brake pads checked and
replaced by your Lexus dealer as soon as
possible. Rotor damage may result if the
pads are not replaced when needed.
It is dangerous to drive the vehicle when
the wear limits of the brake pads and/or
those of the brake discs are exceeded.
■When the vehicle is stopped
●Do not race the engine.
If the shift lever is in any position other
than P or N, the vehicle may acceler-
ate suddenly and unexpectedly, caus-
ing an accident.
●In order to prevent accidents due to
the vehicle rolling away, always keep
depressing the brake pedal while the
engine is running, and apply the park-
ing brake as necessary.
●If the vehicle is stopped on an incline,
in order to prevent accidents caused
by the vehicle rolling forward or back-
ward, always depress the brake pedal
and securely apply the parking brake
as needed.
●Avoid revving or racing the engine.
Running the engine at high speed
while the vehicle is stopped may cause
the exhaust system to overheat, which
could result in a fire if combustible
material is nearby.

1504-1. Before driving
LEXUS NX300 Owners Manual_USA_M78389_en
WARNING
■When the vehicle is parked
●Do not leave glasses, cigarette lighters,
spray cans, or soft drink cans in the
vehicle when it is in the sun.
Doing so may result in the following:
• Gas may leak from a cigarette lighter or spray can, and may lead to a fire.
• The temperature inside the vehicle may cause the plastic lenses and plas-
tic material of glasses to deform or
crack.
• Soft drink cans may fracture, causing the contents to spray over the interior
of the vehicle, and may also cause a
short circuit in the vehicle’s electrical
components.
●Do not leave cigarette lighters in the
vehicle. If a cigarette lighter is in a
place such as the glove box or on the
floor, it may be lit accidentally when
luggage is loaded or the seat is
adjusted, causing a fire.
●Do not attach adhesive discs to the
windshield or windows. Do not place
containers such as air fresheners on
the instrument pane l or dashboard.
Adhesive discs or containers may act
as lenses, causing a fire in the vehicle.
●Do not leave a door or window open if
the curved glass is coated with a met-
allized film such as a silver-colored
one. Reflected sunlight may cause the
glass to act as a lens, causing a fire.
●Always apply the parking brake, shift
the shift lever to P, stop the engine and
lock the vehicle.
Do not leave the vehicle unattended
while the engine is running.
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 engine is running or immediately
after turning the engine off.
Doing so may cause burns.
■When taking a nap in the vehicle
Always turn the engine off. Otherwise, if
you accidentally move the shift lever or
depress the accelerator pedal, this could
cause an accident or fire due to engine
overheating. Additionally, if the vehicle is
parked in a poorly ventilated area,
exhaust gases may collect and enter the
vehicle, 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 brake booster device 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.
●Do not pump the brake pedal if the
engine stalls.
Each push on the brake pedal uses up
the reserve for the power-assisted
brakes.
●The brake system consists of 2 individ-
ual hydraulic systems; if one of the sys-
tems fails, the other w ill 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 (AWD
models)
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.
