1

Stop the engine. Set the parking
brake and shift the shift lever to P.

2

Remove the mud, snow or sand
from around the rear wheels.

3

Place wood, stones or some other
material under the rear wheels to
help provide traction.

4

Restart the engine.

5

Shift the shift lever to D or R and
release the parking brake. Then,
while exercising caution, depress
the accelerator pedal.

■

When it is difficult to free the vehicle

Press the

switch to turn off TRAC.

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 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 rear 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.

Vehicle identification number

The vehicle identification number
(VIN) is the legal identifier for your
vehicle. This is the primary identifica-

registering the ownership of your vehi-
cle.
This number is stamped on the top left
of the instrument panel and in the
engine compartment.

: The engine oil capacity is a reference quantity to be used when changing the engine oil.

Warm up 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 additives 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 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

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 while accelerating or

Fuel information

You must only use unleaded gaso-
line.

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 rating 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..

driving uphill. This is normal and there is

no need for concern.

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.

■

When refueling with gasohol

Take care not to spill gasohol. It can dam-

age your vehicle’s paint.

■

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.
