7-2. Steps to take in an emergency

Start the engine and turn the air
conditioning system on to check
that the radiator cooling fan oper-
ates and to check for coolant leaks
from the radiator or hoses.

The fan operates when the air conditioning

system is turned on immediately after a

cold start. Confirm that the fan is operating

by checking the fan sound and air flow. If it

is difficult to check these, turn the air con-

ditioning system on and off repeatedly.

(The fan may not operate in freezing tem-

peratures.)

If the fan is not operating:
Stop the engine immediately and
contact your Lexus dealer.
If the fan is operating:
Have the vehicle inspected at the
nearest Lexus dealer.

WARNING

■

When inspecting under the hood of

your vehicle

Observe the following precautions.

Failure to do so may result in serious

injury such as burns.

●

If 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.

●

Keep hands and clothing (especially a

tie, a scarf or a muffler) away from the

fan and belts. Failure to do so may

cause the hands or clothing to be

caught, resulting in serious injury.

●

While the engine and radiator are hot,

do not loosen or remove the coolant

inlet cap or coolant reservoir cap.

High temperature steam or coolant

could spray out.

NOTICE

■

When adding engine coolant

Add coolant slowly after the engine has

cooled down sufficiently. Adding cool

coolant to a hot engine too quickly can

cause damage to the engine.

■

To prevent damage to the cooling

system

Observe the following precautions:

●

Avoid contaminating the coolant with

foreign matter (such as sand or dust

etc.).

●

Do not use any coolant additive.

7-2. Steps to take in an emergency

n t

ris

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

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

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

Restart the engine.

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 procedures
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 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.

■

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..

394

8-1. Specifications

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.
