WARNING

■

Installing the spare tire

Failure to follow these precautions could

cause the wheel bolts to loosen and the

tire to fall off, resulting in death or serious

injury.

●

The contact surfaces of the wheel bolt

and wheel are designed specifically to

fit together. When using wheels that

were installed when the vehicle was

shipped from the factory, use special-

ized Lexus genuine wheel bolts. Do

not use wheel bolts designed for other

models, model years or types even if

they are Lexus genuine parts. If the

vehicle does not have wheels that were

installed to the vehicle when it was

shipped from the factory, the fac-

tory-installed wheel bolts may not be

appropriate for the wheel. Contact

either the retailer where the wheels

were purchased or the manufacturer

of the wheels for proper installation

advice.

When removing the battery terminals

●

When the battery terminals are removed,

the information stored in the ECU is

cleared. Before removing the battery ter-

minals, contact your Lexus dealer.

●

If a battery terminal is disconnected, the

doors will not be able to be opened using

the door opener switches and the elec-

tronic key may become trapped in the

vehicle

To prevent the electronic key (mechanical

key) from being locked inside the vehicle,

make sure to remove it from the vehicle

before disconnecting a battery terminal.

●

If the electronic key (mechanical key) is

to be left in the vehicle, make sure to

open a window so an inside manual

release handle can be operated.

■

Charging the battery

The electricity stored in the battery will dis-

charge gradually even when the vehicle is

not in use, due to natural discharge and the

draining effects of certain electrical appli-

ances. If the vehicle is left for a long time,

the battery may discharge, and the engine

may be unable to start. (The battery

recharges automatically during driving.)

■

When recharging or replacing the bat-

tery

●

In some cases, it may not be possible to

unlock the doors using the smart access

system with push-button start when the

battery is discharged. Use the wireless

remote control or the mechanical key to

lock or unlock the doors.

●

The engine may not start on the first

attempt after the battery has recharged

but will start normally after the second

attempt. This is not a malfunction.

●

The engine switch mode is memorized by

the vehicle. When the battery is recon-

nected, the system will return to the

mode it was in before the battery was dis-

charged. Before disconnecting the bat-

tery, turn the engine switch off.

If you are unsure what mode the engine

switch was in before the battery dis-

charged, be especially careful when

reconnecting the battery.

●

If the 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 front wheels

because the front wheels will be locked.

●

Some systems may require initialization.

(



P.559)

●

The Stop & Start system may not auto-

matically stop the engine for up to an

hour.

■

When replacing the battery

●

Use a genuine battery specifically

designed for use with the Stop & Start

system or a battery with equivalent speci-

fications to a genuine battery. If an unsup-

ported battery is used, Stop & Start

system functions may be restricted to

protect the battery. Also, battery perfor-

mance may decrease and the engine may

not be able to restart. Contact your Lexus

dealer for details.

●

Use a battery that the case size is same as

the previous one (LN3), 20 hour rate

capacity (20HR) is equivalent (65Ah) or

greater, and performance rating (CCA)

is equivalent (603A) or greater.

• If the sizes differ, the battery cannot 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 battery may dis-

charge and the engine may not be able to

start.

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.

Also, it may operate for several min-

utes even after the engine switch is

turned off.

●

Do not loosen the radiator cap and the

coolant reservoir caps while the

engine and radiator are hot.

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 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.

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 position

Be careful not to shift the shift position

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 damage to the transmission

and other components

●

Avoid spinning the front wheels and

depressing the accelerator pedal

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-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.

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 war-
ranty.

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.
