be repaired. Contact your Lexus
dealer to service the vehicle.



When the battery is disconnected
or discharged

Readiness codes that are set during ordi-
nary driving are erased.
Also, depending on your driving habits, the
readiness codes may not be completely
set.



When the fuel tank cap is loose

The malfunction indicator lamp comes on
indicating a temporary malfunction and
your vehicle may not pass the I/M test.

The error code in the OBD system will
not be cleared unless the vehicle is
driven 40 or more times.

Contact your Lexus dealer to prepare
the vehicle for re-testing.

Emission inspection and
maintenance (I/M) pro-
grams

Some states have vehicle emission
inspection programs which include
OBD (On Board Diagnostics)
checks. The OBD system monitors
the operation of the emission con-
trol system.

If the malfunction indicator lamp
comes on

Your vehicle may not pass the
I/M test in the following situa-
tions:

When the malfunction indicator
lamp still remains on after sev-

WARNING

The engine compartment contains many

mechanisms and fluids that may move

suddenly, become hot, or become elec-

trically energized. To avoid death or seri-

ous injury, observe the following

precautions.

■

When working on the engine com-

partment

●

Keep hands, clothing and tools away

from the moving fan and engine drive

belt.

●

Be careful not to touch the engine,

radiator, exhaust manifold, etc. right

after driving as they may be hot. Oil

and other fluids may also be hot.

●

Do not leave anything that may burn

easily, such as paper and rags, in the

engine compartment.

●

Do not smoke, cause sparks or expose

an open flame to fuel. Fuel fumes are

flammable.

Parts and tools

■

When working near the electric cool-

ing fan or radiator grille

Be sure the engine switch is off.

With the engine switch in IGNITION

ON mode, the electric cooling fan may

automatically start to run if the air condi-

tioning is on and/or the coolant tempera-

ture is high. (

Safety glasses

Wear safety glasses to prevent flying or

falling material, fluid spray, etc. from get-

ting in your eyes.

NOTICE

■

If the coolant level drops within a short

time of replenishing

Visually check the radiator, hoses, engine

coolant reservoir caps, drain cock and

water pump.

If you cannot find a leak, have your Lexus

dealer test the cap and check for leaks in

the cooling system.

Check the radiator, condenser, inter-
cooler radiator and intercooler sub
radiator and clear away any foreign
objects. If either of the above parts is
extremely dirty or you are not sure of

their condition, have your vehicle
inspected by your Lexus dealer.

The cooling system may be under pres-

sure and may spray hot coolant if the cap

is removed, causing serious injuries, such

as burns.

NOTICE

■

When adding coolant

Coolant is neither plain water nor

straight antifreeze. The correct mixture

of water and antifreeze must be used to

provide proper lubrication, corrosion

protection and cooling. Be sure to read

the antifreeze or coolant label.

■

If you spill coolant

Be sure to wash it off with water to pre-

vent it from damaging parts or paint.

a dangerous loss of braking efficiency. Use

only newly opened brake fluid.

If any washer does not work or the
warning message appears on the
multi-information display, the washer
tank may be empty. Add washer fluid.

WARNING

■

When filling the reservoir

Take care as brake fluid can harm your

hands and eyes and damage painted sur-

faces.

If fluid gets on your hands or in your eyes,

flush the affected area with clean water

immediately.
If you still experience discomfort, see a

doctor.

NOTICE

■

If the fluid level is low or high

It is normal for the brake fluid level to go

down slightly as the brake pads wear out

or when the fluid level in the accumulator

is high.

If the reservoir needs frequent refilling,

there may be a serious problem.

Adding the washer fluid

WARNING

■

When adding washer fluid

Do not add washer fluid when the engine

is hot or running as washer fluid contains

alcohol and may catch fire if spilled on

the engine, etc.

NOTICE

■

Do not use any fluid other than

washer fluid

Do not use soapy water or engine anti-

freeze instead of washer fluid.

Doing so may cause streaking on the

vehicle’s painted surfaces, as well as

damaging the pump leading to problems

of the washer fluid not spraying.

■

Diluting washer fluid

Dilute washer fluid with water as neces-

sary.

Refer to the freezing temperatures listed

on the label of the washer fluid bottle.

Before recharging

When recharging, the battery produces

hydrogen gas which is flammable and

explosive. Therefore, observe the following

precautions before recharging:

●

If recharging with the battery installed on

the vehicle, be sure to disconnect the

ground cable.

●

Make sure the charger is off when con-

necting and disconnecting the charger

cables to the battery.

■

After recharging/reconnecting the bat-

tery

●

Unlocking the doors using the smart

access system with push-button start may

not be possible immediately after recon-

necting the battery. If this happens, use

the wireless remote control or the

mechanical key to lock/unlock the doors.

●

Start the engine with the engine switch in

ACCESSORY mode. The engine may

not start with the engine switch turned off.

However, the engine will operate nor-

mally from the second attempt.

●

The engine switch mode is recorded by

the vehicle. If the battery is reconnected,

the vehicle will return the engine switch

mode to the status it was in before the

battery was disconnected. Make sure to

turn off the engine switch before discon-

necting the battery. Take extra care when

connecting the battery if the engine

switch mode prior to discharge is

unknown.

If the system will not start even after multiple

attempts, contact your Lexus dealer.

■

When to replace your vehicle’s tires

Tires should be replaced if:

●

The treadwear indicators are showing on

a tire.

●

You have tire damage such as cuts, splits,

cracks deep enough to expose the fabric,

and bulges indicating internal damage

●

A tire goes flat repeatedly or cannot be

properly repaired due to the size or loca-

tion of a cut or other damage

If you are not sure, consult with your Lexus

dealer.

■

Tire life

Any tire over 6 years old must be checked

by a qualified technician even if it has sel-

dom or never been used or damage is not

obvious.

■

Maximum load of tire

Check that the maximum load of the

replacement tire is greater than 1/2 of the

Gross Axle Weight Ratings (GAWR) of

either the front axle or the rear axle, which-

ever is greater.
For the GAWR, see the Certification Label.

For the maximum load of the tire, see the

load limit at maximum cold tire inflation

pressure mentioned on the sidewall of the

tire. (

Summer tires

Summer tires are high-speed performance
tires best suited to highway driving under
dry conditions. Since summer tires do not
have the same traction performance as
snow tires, summer tires are inadequate for
