For safety and security
When the power switch is turned to
ON mode, the red indicator light
comes on for 2 seconds then turns off.
Afterward, the gree n indicator light
comes on, indicating that the service is
active.
The following indicator light patterns
indicate specific system usage condi-
tions:
 Green indicator light on = Active
service
 Green indicator light flashing =
Safety Connect call in process
 Red indicator light (except at vehi-
cle start-up) = System malfunction
(contact your Lexus dealer)
 No indicator light (off) = Safety
Connect service not active
■Automatic Collision Notification
In case of either airbag deployment or
severe rear-end collision, the system is
designed to automatically call the
response center. The responding agent
receives the vehicle’s location and
attempts to speak with the vehicle
occupants to assess the level of emer-
gency. If the occupants are unable to
communicate, the ag ent automatically
treats the call as an emergency, con-
tacts the nearest emergency services
provider to describe the situation, and
requests that assistance be sent to the
location.
■Stolen Vehicle Location
If your vehicle is stolen, Safety Connect
can work with local authorities to assist
them in locating and recovering the
vehicle. After filing a police report, call
the Safety Connect response center at
1-800-25-LEXUS (1-800-255-
3987) in the United States, 1-877-
539-8777 in Puerto Rico or 1-800-
265-3987 in Canada, and follow the
prompts for Safety Connect to initiate
this service.
In addition to assisting law enforce-
ment with recovery of a stolen vehicle,
Safety-Connect-equipped vehicle
location data may, under certain cir-
cumstances, be shared with third par-
ties to locate your vehicle. Further
information is available at Lexus.com.
■Emergency Assistance Button
(“SOS”)
In the event of an emergency on the
road, push the “SOS” button to reach
the Safety Connect response center.
The answering agent will determine
your vehicle’s location, assess the
emergency, and dispatch the neces-
sary assistance required.
If you accidentally press the “SOS” button,
tell the response-center agent that you are
not experiencing an emergency.
■Enhanced Roadside Assistance
Enhanced Roadside Assistance adds
GPS data to the already included war-
ranty- based Lexus roadside service.
Subscribers can press the “SOS” but-
ton to reach a Safety Connect
response-center agent, who can help

Driving
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
Management
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.
●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, et c., check that there
is no grass, bush, paper, rags, stone,
sand, etc. adhering or trapped to the
underbody. Clear of f 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 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
vehicle’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 compart-
ment may cause seve re damage to the
hybrid system. Water entering the inte-
rior may cause the hybrid battery
stowed under the re ar seats to short
circuit.
●Water entering the hybrid transmis-
sion and rear electric 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.

4308-1. Specifications
LEXUS NX300h Owners Manual_USA_M78530_en
■Gasoline quality
In very few cases, driveability problems may
be caused by the brand of gasoline you are
using. If driveability problems persist, try
changing the brand of gasoline. If this does
not correct the problem, consult your Lexus
dealer.
■Recommendation of the use of gasoline
containing detergent additives
●Lexus recommends the use of gasoline
that contains detergent additives to avoid
the build-up of engine deposits.
●All gasoline sold in the U.S.A. contains
minimum detergent additives to clean
and/or keep clean intake systems, per
EPA’s lowest additive s concentration pro-
gram.
●Lexus strongly recommends the use of
Top Tier Detergent Gasoline. For more
information on Top Tier Detergent Gaso-
line and a list of marketers, please go to
the official websit e www.toptiergas.com.
■Recommendation of the use of low
emissions gasoline
Gasolines containing oxygenates such as
ethers and ethanol, as well as reformulated
gasolines, are available in some cities.
These fuels are typically acceptable for use,
providing they meet other fuel require-
ments. Lexus recommends these fuels, since the
formulations allow for reduced vehicle
emissions.
■Non-recommendation of the use of
blended gasoline
●Use only gasoline containing up to 15%
ethanol.
DO NOT use any flex-fuel or gasoline
that could contain more than 15% etha-
nol, including from
any pump labeled
E30 (30% ethanol ), E50 (50% etha-
nol ), E85 (85% ethanol ) (which
are only some examples of fuel contain-
ing more than 15% ethanol).
●If you use gasohol in your vehicle, be sure
that 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 gas-
oline containing MMT
Some gasoline contains an octane enhanc-
ing additive called MMT (Methylcyclopen-
tadienyl Manganese Tricarbonyl).
Lexus does not recommend the use of gas-
oline that contains MMT. If fuel containing
MMT is used, your emission control system
may be adversely affected.
The malfunction indicator lamp on the
instrument cluster may come on. If this hap-
pens, contact your Lexus dealer for service.
■If your engine knocks
●Consult your Lexus dealer.
●You may occasionally notice light knock-
ing for a short time wh ile accelerating or
driving uphill. This is normal and there is
no need for concern.
Fuel information
You must only use unleaded gaso-
line in your vehicle.
Select octane rating 87 (Research
Octane Number 91) or higher. Use
of unleaded gasoline with an octane
rating lower than 87 may result in
engine knocking. Persistent knock-
ing can lead to engine damage.
At minimum, the gasoline you use
should meet the specifications of
ASTM D4814 in the U.S.A.
