LEXUS NX300h Owners Manu-
al_USA_OM78212U 4
Driving  Use fluids that are appropriate to
the prevailing outside temperatures. •Engine oil
• Engine/power control unit coolant
•Washer fluid
 Have a service technician inspect
the condition of the 12-volt battery.
 Have the vehicle fitted with four
snow tires or purchase a set of tire
chains for the front tires *
.Ensure that all tires are the same size and
brand, and that chains match the size of the
tires. *
: Tire chains cannot be mounted on the
225/60R18 tires.
Perform the following according to the
driving conditions:
 Do not try to forcibly open a window
or move a wiper that is frozen. Pour
warm water over the frozen area to
melt the ice. Wipe away the water Winter driving tips Carry out the necessary prepara-
tions and inspections before driving
the vehicle in winter. Always drive
the vehicle in a manner appropriate
to the prevailing weather condi-
tions.
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.

Checking the oil type and prepar-
ing the items needed
Make sure to check the oil type and
prepare the items needed before add-
ing oil.
 Engine oil selection → P.402
 Oil quantity (Low Full) 1.6 qt. (1.5 L, 1.3 Imp.qt.)
 Items Clean funnel
■
Adding engine oil
If the oil level is below or near the low
level mark, add engine oil of the same
type as that already in the engine. 1 Remove the oil filler cap by turning
it counterclockwise.
2 Add engine oil slowly, checking the
dipstick.
3 Install the oil filler cap by turning it
clockwise. ■
Engine oil consumption
A certain amount of engine oil will be con-
sumed while driving. In the following situa-
tions, oil consumption may increase, and
engine oil may need to be refilled in
between oil maintenance intervals. ●
When the engine is new, for example
directly after purchasing the vehicle or
after replacing the engine ●
If low quality oil or oil of an inappropriate
viscosity is used ●
When driving at high engine speeds or
with a heavy load, when towing, or when
driving while accelera ting or decelerat-
ing frequently ●
When leaving the engine idling for a long
time, or when driving frequently through
heavy traffic
■
After changing the engine oil
The engine oil maintenance data should be
reset. Perform the fo llowing procedures:

Oil capacity (Drain and refill [Reference*]) *
: The engine oil capacity is a reference quantity to be used when changing the engine oil.
Warm up the engine and turn off the hybrid system, wait more than 5 minutes, and check
the oil level on the dipstick.■
Engine oil selection
“Toyota Genuine Motor Oil” is used in
your Lexus vehicle. Use Lexus
approved “Toyota Genuine Motor Oil”
or equivalent to satisfy the following
grade and viscosity.
Oil grade: ILSAC GF-5 multigrade
engine oil
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice for
good fuel economy and good starting
in cold weather.
If SAE 0W-20 is not available, SAE 5W-20 oil may be used. However, it
must be replaced with SAE 0W-20 at
the next oil change.
Outside temperature
Oil viscosity (0W-20 is explained here Type Permanent magnet synchronous motor
Maximum output 50 kW
Maximum torque 103 ft•lbf (139 N•m, 14.2 kgf•m)
Hybrid battery (traction battery) Type Nickel-Metal hydride battery
Voltage 7.2 V/module
Capacity 6.5 Ah (3HR)
Quantity 34 modules
Overall voltage 244.8 V
Lubrication system With filter 4.6 qt. (4.4 L, 3.9 Imp.qt.)
Without filter 4.2 qt. (4.0 L, 3.5 Imp.qt.)

Vehicle specifications as an example):
• The 0W in 0W-20 indicates the
characteristic of the oil which allows
cold startability. Oils with a lower
value before the W allow for easier
starting of the engine in cold
weather.
• The 20 in 0W-20 indicates the vis-
cosity characteristic of the oil when
the oil is at high temperature. An oil
with a higher viscosity (one with a
higher value) may be better suited if
the vehicle is operated at high
speeds, or under extreme load con-
ditions. How to read oil container label:
The International Lubricant Specifica-
tion Advisory Committee (ILSAC)
Certification Mark is added to some oil
containers to help you select the oil you
should use.
