3867-2. Steps to take in an emergency
One of the following may be the cause
of the problem:
The electronic key may not be func-
tioning properly. ( P.390)
 There may not be sufficient fuel in
the vehicle’s tank.
Refuel the vehicle. ( P.174)
 There may be a malfunction in the
immobilizer system. ( P.67)
 There may be a malfunction in the
steering lock system.
 The hybrid system may be malfunc-
tioning due to an electrical problem
such as electronic key battery
depletion or a blown fuse. However,
depending on the type of malfunc-
tion, an interim measure is available
to start the hybrid system.
 For vehicles sold in except Canada:
There is a possibility that the tem-
perature of the hybrid battery (trac-
tion battery) is extremely low
(approximately below -22°F [-
30°C]). ( P.63, 148)
WARNING
QSpeed limit when using the compact
spare tire
Do not drive at speeds in excess of 50
mph (80 km/h) when a compact spare
tire is installed on the vehicle.
The compact spare tire is not designed
for driving at high speeds. Failure to
observe this precaution may lead to an
accident causing death or serious injury.
QAfter using the tools and jack
Before driving, make sure all the tools
and jack are securely in place in their
storage location to reduce the possibility
of personal injury during a collision or
sudden braking.
NOTICE
QBe careful when driving over bumps
with the compact spare tire installed
on the vehicle
The vehicle becomes lower when driving
with the compact spare tire compared to
when driving with standard tires. Be
careful when driving over uneven road
surfaces.
QDriving with tire chains and the com-
pact spare tire
Do not fit tire chains to the compact
spare tire.
Tire chains may damage the vehicle
body and adversely affect driving perfor-
mance.
QWhen replacing the tires
When removing or fitting the wheels,
tires or the tire pressure warning valve
and transmitter, contact your Lexus
dealer as the tire pressure warning valve
and transmitter may be damaged if not
handled correctly.
If the hybrid system will not
start
Reasons for the hybrid system not
starting vary depending on the situ-
ation. Check the following and per-
form the appropriate procedure:
The hybrid system will not start
even though the correct starting
procedure is being followed.

dropped and the vehicle may be driven
normally.
However, if the message appears again
frequently, contact your Lexus dealer.
WARNING
QWhen inspecting under the hood of
your vehicle
Observe the following precautions.
Failure to do so may result in serious
injury such as burns.
OIf steam is seen coming from under the
hood, do not open the hood until the
steam has subsided. The engine com-
partment may be very hot.
OAfter the hybrid system has been
turned off, check that the “READY”
indicator are off.
When the hybrid system is operating,
the gasoline engine may automatically
start, or the cooling fan may suddenly
operate even if the gasoline engine
stops. Do not touch or approach rotat-
ing parts such as the fan, which may
lead to fingers or clothing (especially a
tie, a scarf or a muffler) getting caught,
resulting in serious injury.
ODo not loosen the coolant inlet cap or
coolant reservoir caps while the hybrid
system and radiator are hot.
High temperature steam or coolant
could spray out.
NOTICE
QWhen adding engine/power control
unit coolant
Add coolant slowly after the hybrid sys-
tem has cooled down sufficiently. Adding
cool coolant to a hot hybrid system too
quickly can cause damage to the hybrid
system.
QTo prevent damage to the cooling
system
Observe the following precautions:
OAvoid contaminating the coolant with
foreign matter (such as sand or dust
etc.).
ODo not use any coolant additive.

Outside temperature
Oil viscosity (0W-16 is explained here
as an example):
• The 0W in 0W-16 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 16 in 0W-16 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:
API registered mark is added to some
oil containers to help you select the oil
you should use.

QGasoline quality
In very few cases, dr iveability 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.
QRecommendation of the use of gasoline
containing detergent additives
OLexus recommends the use of gasoline
that contains detergent additives to avoid
the build-up of engine deposits.
OAll gasoline sold in the U.S.A. contains
minimum detergent additives to clean
and/or keep clean intake systems, per
EPA’s lowest additives concentration
program.
OLexus strongly recommends the use of
Top Tier Detergent Gasoline. For more
information on Top Tier Detergent Gas-
oline and a list of marketers, please go to
the official website www.toptiergas.com.
QRecommendation 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.
QNon-recommendation of the use of
blended gasoline
OUse 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%
ethanol [ ]), E85 (85% ethanol [ ])
(which are only some examples of fuel
containing more than 15% ethanol).
OIf you use gasohol in your vehicle, be sure
that it has an octane rating no lower than
87.
OLexus does not recommend the use of
gasoline containing methanol.
QNon-recommendation of the use of gas-
oline containing MMT
Some gasoline contains an octane enhanc-
ing additive called MMT (Methylcyclo-
pentadienyl 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.
QIf your engine knocks
OConsult your Lexus dealer.
OYou may occasionally notice light knock-
ing for a short time while accelerating or
driving uphill. This is normal and there is
no need for concern.
Fuel information
You must only use unleaded gaso-
line.
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.

Chafer This information has been prepared in
accordance with regulations issued by
the National Highway Traffic Safety
Administration of th
e U.S. Department
of Transportation.
It provides the purchasers and/or pro-
spective purchasers of Lexus vehicles
with information on uniform tire quality
grading.
Your Lexus dealer will help answer any
questions you may have as you read this
information.
QDOT quality grades
All passenger vehicle tires must con-
form to Federal Safety Requirements
in addition to these grades. Quality
grades can be found where applicable
on the tire sidewall between tread
shoulder and maximum section width.
For example: Treadwear 200 Traction AA
Temperature A
QTreadwear
The treadwear grade is a comparative
rating based on the wear rate of the
tire when tested under controlled con-
ditions on a specified government test
course.
For example, a tire graded 150 would
wear one and a half (1 - 1/2) times as well
on the government course as a tire graded
100.
The relative performance of tires depends
upon the actual conditions of their use.
Performance may differ significantly from
the norm due to variations in driving habits,
service practices and differences in road
characteristics and climate.

Uniform Tire Quality Grading

4168-1. Specifications
QTraction AA, A, B, C
The traction grades, from highest to
lowest, are AA, A, B and C, and they
represent the tire’s ability to stop on
wet pavement as measured under con-
trolled conditions on specified govern-
ment test surfaces of asphalt and
concrete.
A tire marked C may have poor traction
performance.
Warning: The traction grade assigned to
this tire is based on braking (straight
ahead) traction tests and does not include
cornering (turning) traction.
QTemperature A, B, C
The temperature grades are A (the
highest), B, and C, representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat when tested under controlled condi-
tions on a specified indoor laboratory
test wheel.
Sustained high temperature can cause the
material of the tire to degenerate and
reduce tire life, and excessive temperature
can lead to sudden tire failure.
Grade C corresponds to a level of perfor-
mance which all passenger car tires must
meet under the Federal Motor Vehicle
Safety Standard No. 109.
Grades B and A represent higher levels of
performance on the laboratory test wheel
than the minimum required by law.
Warning: The temperature grades of a tire
assume that it is properly inflated and not
overloaded.
Excessive speed, underinflation, or exces-
sive loading, either separately or in combi-
nation, can cause heat buildup and
possible tire failure.
