4067-2. Steps to take in an emergency
LEXUS NX300 Owners Manual_USA_M78389_en
1Stop the engine. Shift the shift lever
to P and set the parking brake.
2
Remove the mud, snow or sand
from around the front wheels.
3
Place wood, stones or some other
material under the front wheels to
help provide traction.
4
Restart the engine.
5
Shift the shift lever to D or R,
release the parking brake. Then,
while exercising caution, depress
the accelerator pedal.
■When it is difficult to free the vehicle
Press to turn off TRAC. ( P.261)
If the vehicle becomes stuck
Carry out the following proce-
dures if the tires spin or the vehicle
becomes stuck in mud, dirt or snow:
Recovering procedure
WARNING
■When attempting to free a stuck vehi-
cle
If you choose to push the vehicle back
and forth to free it, make sure the sur-
rounding area is clear to avoid striking
other vehicles, objects or people. The
vehicle may also lunge forward or lunge
back suddenly as it becomes free. Use
extreme caution.
■When shifting the shift lever
Be careful not to shif t the shift lever with
the accelerator pedal depressed.
This may lead to un expected rapid accel-
eration of the vehicle that may cause an
accident resulting in death or serious
injury.
NOTICE
■To avoid damage to the transmission
and other components
●Avoid spinning the front wheels and
depressing the accelerator pedal
more than necessary.
●If the vehicle remains stuck even after
these procedures are performed, the
vehicle may require towing to be freed.

■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 engine, 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
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.

■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
91.
●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
Fuel information
You must only use unleaded gaso-
line in your vehicle.
Select premium unleaded gasoline
with an octane rating of 91
(Research Octane Number 96) or
higher required for optimum
engine performance and fuel econ-
omy. If the octane ra ting is less than
91,damage to the engine may occur
and may void the vehicle warranty.
At minimum, the gasoline you use
should meet the specifications of
ASTM D4814 in the U.S.A.
