■

Starting the hybrid system when the

12-volt battery is discharged

The hybrid system cannot be started by

push-starting.

■

To prevent 12-volt battery discharge

●

Turn off the headlights and the audio sys-

tem while the hybrid system is off.

●

Turn off any unnecessary electrical com-

ponents when the vehicle is running at a

low speed for an extended period, such

as in heavy traffic.

■

When the 12-volt battery is removed or

discharged

●

Information stored in the ECU is cleared.

When the 12-volt battery is depleted,

have the vehicle inspected at your Lexus

dealer.

●

Some systems may require initialization.

(



P.524)

■

When removing the 12-volt battery ter-

minals

When the 12-volt battery terminals are

removed, the information stored in the

ECU is cleared. Before removing the

12-volt battery terminals, contact your

Lexus dealer.

■

Charging the 12-volt battery

The electricity stored in the 12-volt battery

will discharge gradually even when the

vehicle is not in use, due to natural dis-

charge and the draining effects of certain

electrical appliances. If the vehicle is left for

a long time, the 12-volt battery may dis-

charge, and the hybrid system may be

unable to start. (The 12-volt battery

recharges automatically while the hybrid

system is operating.)

■

When recharging or replacing the

12-volt battery

●

In some cases, it may not be possible to

unlock the doors using the smart access

system with push-button start when the

12-volt battery is discharged. Use the

wireless remote control or the mechani-

cal key to lock or unlock the doors.

●

The hybrid system may not start on the

first attempt after the 12-volt battery has

recharged but will start normally after the

second attempt. This is not a malfunction.

●

The power switch mode is memorized by

the vehicle. When the 12-volt battery is

reconnected, the system will return to the

mode it was in before the 12-volt battery

was discharged. Before disconnecting

the 12-volt battery, turn the power switch

off.

If you are unsure what mode the power

switch was in before the 12-volt battery

discharged, be especially careful when

reconnecting the 12-volt battery.

●

If the 12-volt battery discharges, it may

not be possible to shift the shift position to

other positions. In this case, the vehicle

cannnot be towed without lifting both

rear wheels because the rear wheels will

be locked.

481

7-2. Steps to take in an emergency

n t

ris

■

When replacing the 12-volt battery

●

Use a Central Degassing type 12-volt

battery (European Regulations).

●

Use a 12-volt battery with the same case

size as the previous 12-volt battery and an

equivalent 20 hour rate capacity (20HR)

or greater.

• If the sizes differ, the 12-volt battery can-

not be properly secured.

• If the 20 hour rate capacity is low, even if

the time period where the vehicle is not

used is a short time, the 12-volt battery

may discharge and the hybrid system

may not be able to start.

●

Use a 12-volt battery with a handle. If a

12-volt battery without a handle is used,

removal is more difficult.

●

After replacing, firmly attach the follow-

ing items to the exhaust hole of the

12-volt battery.

• Use the exhaust hose that was attached

to the 12-volt battery before replacing

and confirm that it is firmly connected to

the hole section of the vehicle.

• Use the exhaust hole plug included with

the 12-volt battery replaced or the one

installed on the 12-volt battery prior to

the replacement. (Depending on the

12-volt battery to be replaced, the

exhaust hole may be plugged.)

For details, consult your Lexus dealer.

WARNING

■

When removing the 12-volt battery

terminals

Always remove the negative (-) terminal

first. If the positive (+) terminal contacts

any metal in the surrounding area when

the positive (+) terminal is removed, a

spark may occur, leading to a fire in addi-

tion to electrical shocks and death or

serious injury.

■

Avoiding 12-volt battery fires or

explosions

Observe the following precautions to

prevent accidentally igniting the flamma-

ble gas that may be emitted from the

12-volt battery:

●

Make sure each jumper cable is con-

nected to the correct terminal and that

it is not unintentionally in contact with

any other than the intended terminal.

WARNING

●

Do not allow the other end of the

jumper cable connected to the “+” ter-

minal to come into contact with any

other parts or metal surfaces in the

area, such as brackets or unpainted

metal.

●

Do not allow the + and - clamps of the

jumper cables to come into contact

with each other.

●

Do not smoke, use matches, cigarette

lighters or allow open flame near the

12-volt battery.

■

12-volt battery precautions

The 12-volt battery contains poisonous

and corrosive acidic electrolyte, while

related parts contain lead and lead com-

pounds. Observe the following precau-

tions when handling the 12-volt battery:

482

7-2. Steps to take in an emergency

●

When working with the 12-volt battery,

always wear safety glasses and take

care not to allow any battery fluids

(acid) to come into contact with skin,

clothing or the vehicle body.

●

Do not lean over the 12-volt battery.

●

In the event that battery fluid comes

into contact with the skin or eyes,

immediately wash the affected area

with water and seek medical attention.

Place a wet sponge or cloth over the

affected area until medical attention

can be received.

●

Always wash your hands after handling

the 12-volt battery support, terminals,

and other battery-related parts.

●

Do not allow children near the 12-volt

battery.

■

After recharging the 12-volt battery

Have the 12-volt battery inspected at

your Lexus dealer as soon as possible.

If the 12-volt battery is deteriorating, con-

tinued use may cause the 12-volt battery

to emit a malodorous gas, which may be

detrimental to the health of passengers.

■

When replacing the 12-volt battery

●

When the vent plug and indicator are

close to the hold down clamp, the bat-

tery fluid (sulfuric acid) may leak.

●

For information regarding 12-volt bat-

tery replacement, contact your Lexus

dealer.

●

After replacing, securely attach the

exhaust hose and exhaust hole plug to

the exhaust hole of the replaced

12-volt battery. If not properly installed,

gases (hydrogen) may leak into the

vehicle interior, and there is the possi-

ble danger of the gas igniting and

exploding.

NOTICE

■

When handling jumper cables

When connecting the jumper cables,

ensure that they do not become entan-

gled in the cooling fan or engine drive

belt.

■

When connecting jumper cables

Make sure to connect jumper cables to

the specified terminals and connecting

point. Failure to do so may adversely

affect the electronic devices or damage

to them.

■

To prevent damaging the vehicle

The exclusive jump starting terminal is to

approved “Toyota Genuine Motor Oil”
or equivalent to satisfy the following
grade and viscosity.
Oil grade: ILSAC GF-6A 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.

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..

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.

This information has been prepared in
accordance with regulations issued by
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 condi-
tions 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.
