Preparation for winter
WARNING
■
Driving with snow tires
Observe the following precautions to
reduce the risk of accidents.
Failure to do so may result in a loss of
vehicle control and cause death or seri-
ous injury.
●
Use tires of the specified size.
●
Maintain the recommended level of air
pressure. ●
Do not drive in excess of 75 mph (120
km/h), regardless of the type of snow
tires being used. ●
Use snow tires on all, not just some
wheels. ■
Driving with tire chains
Observe the following precautions to
reduce the risk of accidents.
Failure to do so may result in the vehicle
being unable to be driven safely, and may
cause death or serious injury. ●
Do not drive in excess of the speed
limit specified for the tire chains being
used, or 30 mph (50 km/h), which-
ever is lower. ●
Avoid driving on bumpy road surfaces
or over potholes. ●
Avoid sudden acceleration, abrupt
steering, sudden br aking and shifting
operations that cause sudden engine
braking. ●
Slow down sufficiently before entering
a curve to ensure that vehicle control is
maintained.
NOTICE■
Repairing or replacing snow tires
Request repairs or replacement of snow
tires from Lexus dealers or legitimate tire
retailers.
This is because the removal and attach-
ment of snow tires affects the operation
of the tire pressure warning valves and
transmitters.
Before driving the vehicle

260 4-6. Driving tips
LEXUS NX300h Owners Manu-
al_USA_OM78212U Your vehicle is not designed to be
driven off-road. However, in the event
that off-road driving cannot be
avoided, please observe the following
precautions to help avoid the areas
prohibited to vehicles.
 Drive your vehicle only in areas
where off-road vehicles are permit-
ted to travel.
 Respect private property. Get
owner’s permission before entering
private property.
 Do not enter areas that are closed. Honor gates, barriers and signs that
restrict travel.
 Stay on established roads. When
conditions are wet, driving tech-
niques should be changed or travel
delayed to prevent damage to
roads.
 Avoid driving on very steep, slippery
roads and other surfaces, such as
sand, where the tires are liable to
lose traction. Your vehicle may not
perform as well as conventional
AWD on-road vehicles on these
surfaces. ■
Additional informatio n for off-road driv-
ing 
For owners in U.S. mainland, Hawaii and
Puerto Rico:
To obtain additional information pertaining
to driving your vehicle off-road, consult the
following organizations. ●
State and Local Parks and Recreation
Departments ●
State Motor Vehicle Bureau ●
Recreational Vehicle Clubs ●
U.S. Forest Service and Bureau of Land
ManagementWARNING●
Avoid sharp turns or abrupt maneu-
vers, if at all possible.
Failure to operate this vehicle correctly
may result in loss of control or vehicle
rollover causing death or serious
injury.●
Loading cargo on the roof luggage
carrier (if equipped ) will make the cen-
ter of the vehicle gravity higher. Avoid
high speeds, sudden starts, sharp
turns, sudden braking or abrupt
maneuvers, otherwise it may result in
loss of control or vehicle rollover due
to failure to operate this vehicle cor-
rectly.●
Always slow down in gusty crosswinds.
Because of its profile and higher cen-
ter of gravity, your vehicle is more sen-
sitive to side winds than an ordinary
passenger car. Slowing down will allow
you to have better control.●
Do not drive horizontally across steep
slopes. Driving straig ht up or straight
down is preferred. Your vehicle (or any
similar off-road vehicle) can tip over
sideways much more easily than for-
ward or backward.
Off-road driving WARNING
■
Off-road driving precautions
Always observe the following precau-
tions to minimize the risk of death or seri-
ous injury or damage to your vehicle:
●
Drive carefully when off the road. Do
not take unnecessary risks by driving in
dangerous places.
●
Do not grip the steering wheel spokes
when driving off-road. A bad bump
could jerk the wheel and injure your
hands. Keep both hands and especially
your thumbs on the outside of the rim.

LEXUS NX300h Owners Manu-
al_USA_OM78212U 4
Driving WARNING●
Always check your brakes for effec-
tiveness immediately after driving in
sand, mud, water or snow.●
After driving through tall grass, mud,
rock, sand, water, etc., check that there
is no grass, bush, paper, rags, stone,
sand, etc. adhering or trapped to the
underbody. Clear off any such matter
from the underbody. If the vehicle is
used with these materials trapped or
adhering to the underbody, a break-
down or fire could occur.●
When driving off-road or in rugged
terrain, do not drive at excessive
speeds, jump, make sh arp turns, strike
objects, etc. This may cause loss of
control or vehicle rollover causing
death or serious injury. You are also
risking expensive damage to your
vehicle’s suspension and chassis.
NOTICE■
To prevent water damage
Take all necessary sa fety measures to
ensure that water da mage to the hybrid
battery (traction battery), hybrid system
or other components does not occur. ●
Water entering the engine compart-
ment may cause severe damage to the
hybrid system. Water entering the inte-
rior may cause the hybrid battery
stowed under the rear seats to short
circuit.
●
Water entering the hybrid transmis-
sion and rear electr ic motor (traction
motor) will cause deterioration in
transmission quality. The malfunction
indicator may come on, and the vehi-
cle may not be drivable.
●
Water can wash the grease from wheel
bearings, causing rusting and prema-
ture failure, and may also enter the
hybrid transmission case, reducing the
gear oil’s lubricating qualities. ■
When you drive through water
If driving through water, such as when
crossing shallow streams, first check the
depth of the water and the bottom of the
riverbed for firmness. Drive slowly and
avoid deep water. ■
Inspection after off-road driving ●
Sand and mud that has accumulated
around brake discs may affect braking
efficiency and may damage brake sys-
tem components. ●
Always perform a maintenance
inspection after each day of off-road
driving that has taken you through
rough terrain, sand, mud, or water. For
scheduled maintena nce information,
refer to the “Warranty and Services
Guide/Owner’s Manual Supplement/
Scheduled Maintenance”.
