For safety and security
NX300h_U_OM78007U ■
If a warning light comes on, a warning message is displayed, or the 12-volt battery is dis-
connected
The hybrid system may not start. In this case, try to start the system again. If the “READY”
indicator does not come on, contact your Lexus dealer. ■
Running out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be started, refuel the
vehicle with at least enough gasoline to make the low fuel level warning light (  P. 5 6 7 )
go off. If there is only a small amount of fu el, the hybrid system may not be able to start.
(The standard amount of fuel is about 2.7 gal. [10.1 L, 2.2 Imp.gal.], when the vehicle is on
a level surface. This value may vary when the vehicle is on a slope. Add extra fuel when
the vehicle is inclined.) ■
Electromagnetic waves ●
High voltage parts and cables on hybrid ve hicles incorporate electromagnetic shield-
ing, and therefore emit approximately the same amount of electromagnetic waves as
conventional gasoline powered vehicl es or home electronic appliances.●
Your vehicle may cause sound interference in some third party-produced radio parts. ■
Hybrid battery (traction battery)
The hybrid battery (traction battery) has a limited service life. The lifespan of the hybrid
battery (traction battery) can change in accordance with driving style and driving condi-
tions.

High voltage precautions
This vehicle has high voltage DC and AC systems as well as a 12-volt system. DC and
AC high voltage is very dangerous and can cause severe burns and electric shock that
may result in death or serious injury. ●
Never touch, disassemble, remove or replace the high voltage parts, cables or their
connectors. ●
The hybrid system will become hot after star ting as the system uses high voltage. Be
careful of both the high voltage and the hi gh temperature, and always obey the warn-
ing labels attached to the vehicle. ●
Never try to open the service plug access
hole located underneath the rear seats. The
service plug is used only when the vehicle is
serviced and is subject to high voltage.

Off-road driving precautions
Always observe the following precautions to minimize the risk of death or serious
injury or damage to your vehicle: ●
Drive carefully when off the road. Do not ta ke unnecessary risks by driving in danger-
ous 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. ●
Always check your brakes for effectivenes s 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, et c. adhering or trap ped to the underbody.
Clear off any such matter from the underbody. If the vehicle is used with these materi-
als trapped or adhering to the underb ody, a breakdown or fire could occur.●
When driving off-road or in rugged terrai n, do not drive at excessive speeds, jump,
make sharp 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 vehi-
cle’s suspension and chassis.
NOTICE ■
To prevent water damage
Take all necessary safety measures to ensure that water damage to the hybrid battery
(traction battery), hybrid system or other components does not occur. ●
Water entering the engine compartment may cause severe damage to the hybrid
system. Water entering the interior may cause the hybrid battery stowed under the
rear seats to short circuit. ●
Water entering the hybrid transmission and rear electric motor (traction motor) will
cause deterioration in transmission qualit y. The malfunction indicator may come on,
and the vehicle may not be drivable. ●
Water can wash the grease from wheel be arings, causing rusting and premature fail-
ure, and may also enter the hybrid transmission case, reducing the gear oil’s lubricat-
ing 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 system components. ●
Always perform a maintenance inspection after each day of off-road driving that has
taken you through rough terr ain, sand, mud, or water. For scheduled maintenance
information, refer to the “Warranty and Services Guide/Owner’s Manual Supple-
ment/Scheduled Maintenance”.

Maintenance and care
NX300h_U_OM78007UEmission inspection and maintenance (I/M) programsThe OBD system determines that a problem exists somewhere in the emission
control system. Your vehicle may not pa ss the I/M test and may need to be
repaired. Contact your Lexus dealer to service the vehicle. ●
When the 12-volt battery is disconnected or discharged
Readiness codes that are set during ordinary driving are erased.
Also, depending on your driving habits, the readiness codes may not be com-
pletely set. ●
When the fuel tank cap is loose
The malfunction indicator lamp comes on indicating a temporary malfunction
and your vehicle may not pass the I/M test.
The error code in the OBD system will not be cleared unless the vehicle is driven
40 or more times.
Contact your Lexus dealer to prepare the vehicle for re-testing.Some states have vehicle emission inspection programs which include OBD
(On Board Diagnostics) checks. The OBD system monitors the operation of
the emission control system.
If the malfunction indicator lamp comes on
Your vehicle may not pass the I/M test in the following situations:
When the malfunction indicator lamp s till remains on af ter several driv-

Recommendation of the use of cleaner burning gasoline
Cleaner burning gasoline, including reformul ated gasoline that contains oxygenates
such as ethanol or MTBE (Methyl Tertiary Butyl Ether) is ava ilable in many areas.
Lexus recommends the use of cleaner bu rning gasoline and appropriately blended
reformulated gasoline. These types of gaso line provide excellent vehicle performance,
reduce vehicle emissions and improve air quality. ■
Non-recommendation of the use of blended gasoline
●
If you use gasohol in your vehicle, be sure th at it has an octane rating no lower than 87.●
Lexus does not recommend the use of gasoline containing methanol.■
Non-recommendation of the use of gasoline containing MMT
Some gasoline contains an octane enhancing additive called MMT
(Methylcyclopentadienyl Manganese Tricarbonyl).
Lexus does not recommend the use of gasolin e that contains MMT. If fuel containing
MMT is used, your emission control system may be adversely affected.
The malfunction indicator lamp on the instru ment cluster may come on. If this happens,
contact your Lexus dealer for service. ■
If your engine knocks ●
Consult your Lexus dealer. ●
You may occasionally notice light knocking fo r a short time while accelerating or driv-
ing uphill. This is normal and there is no need for concern. ●
Use only gasoline containing up to 15% etha-
nol.
DO NOT use any flex-fuel or gasoline that
could contain more than 15% ethanol, includ-
ing from any pump labeled E30, E50, E85
(which are only some examples of fuel con-
taining more than 15% ethanol). DO NOT use gasoline
containing more than
15% ethanol.
(30% ethanol)
(50% ethanol)
(85% ethanol)
