7-2. Steps to take in an emergency

After the hybrid system has cooled
down, inspect the hoses and radia-
tor core (radiator) for any leaks.

Radiator

Cooling fan

If a large amount of coolant leaks, immedi-
ately contact your Lexus dealer.

The coolant level is satisfactory if it
is between the “FULL” and “LOW”
lines on the reservoir.

Reservoir

“FULL” line

“LOW” line

Add coolant if necessary.

Water can be used in an emergency if

power control unit coolant is unavailable.

After stopping the hybrid system
and waiting for 5 minutes or more,
start the hybrid system again and
check if “Hybrid system overheated
Output power reduced” is shown
on the multi-information display.

If the message does not disappear:

Stop the hybrid system and contact your

Lexus dealer.
If the message is not displayed:

The hybrid system temperature has

dropped and the vehicle may be driven

normally.
However, if the message appears again fre-

quently, contact your 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.

391

7-2. Steps to take in an emergency

When trouble

ari

ses

Stop the hybrid system. 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 hybrid system.

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.

WARNING

●

After 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.

●

Do 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

■

When 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.

■

To prevent damage to the cooling sys-

tem

Observe the following precautions:

●

Avoid contaminating the coolant with

foreign matter (such as sand or dust

etc.).

●

Do not use any coolant additive.

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

7-2. Steps to take in an emergency

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 following
grade and viscosity.
Oil grade: API SN/RC 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.

Oil viscosity (0W-16 is explained here
as an example):

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.

■

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.

■

Gasoline quality standards

●

Automotive manufacturers in the U.S.A.,

Europe and Japan have developed a

specification for fuel quality called the

World-Wide Fuel Charter (WWFC),

which is expected to be applied world-

wide.

●

The WWFC improves air quality by low-

ering emissions in vehicle fleets, and

improves customer satisfaction through

better performance.

■

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).

Fuel information

You must only use unleaded gaso-
line.

Select premium unleaded gasoline
with an octane rating of 87
(Research Octane Number 91) or
higher required for optimum
engine performance and fuel econ-
omy. If the octane rating is less than
87, damage to the engine may
occur and may void the vehicle war-
ranty.

At minimum, the gasoline you use
should meet the specifications of
ASTM D4814 in the U.S.A.

402

8-1. Specifications

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.

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 dam-

age your vehicle’s paint.
