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 shift the shift lever with 

the accelerator pedal depressed. 

This may lead to unexpected rapid accel-

eration of the vehicle that may cause an 

accident resulting in death or serious 

injury.

NOTICE

■

To avoid damaging 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.

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 follow-
ing grade and viscosity.
Oil grade: 

ILSAC GF-6B multigrade engine oil
Recommended viscosity:
SAE 0W-16
SAE 0W-16 is the best choice for 
good fuel economy and good starting 
in cold weather.
If SAE 0W-16 is not available, SAE 
0W-20 oil may be used. However, it 
must be replaced with SAE 0W-16 at 
the next oil change.

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.

■

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 additives concentration 

program.

●

Lexus 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.

■

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% 

ethanol [

]), E85 (85% ethanol [

]) 

(which are only some examples of fuel 
containing 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 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.

NOTICE

■

Notice on fuel quality

●

Do not use improper fuels. If improper 

fuels are used, the engine will be dam-

aged.

●

Do not use leaded gasoline. 

Leaded gasoline can cause damage to 

your vehicle’s three-way catalytic con-

verters causing the emission control 

system to malfunction.

●

Do not use gasohol other than the type 

previously stated. 

Other gasohol may cause fuel system 

damage or vehicle performance prob-

lems.

●

Using unleaded gasoline with an 

octane number or rating lower than 

the level previously stated may cause 

persistent heavy knocking. 

At worst, this may lead to engine dam-

age and will void the vehicle warranty.

■

Fuel-related poor driveability

If poor driveability (poor hot starting, 

vaporization, engine knocking, etc.) is 

encountered after using a different type 

of fuel, discontinue the use of that type of 

fuel.

■

When refueling with gasohol

Take care not to spill gasohol. It can 

damage your vehicle’s paint.

This information has been prepared in

the National Highway Traffic Safety 
Administration of the 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.

■

DOT 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

■

Treadwear

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.

■

Traction 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.

■

Temperature 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.
