Repair and replacement

It is recommended that genuine Lexus parts

be used for repairs to ensure performance

of each system. If non-Lexus parts are used

in replacement or if a repair shop other than

a Lexus dealer performs repairs, confirm

the warranty coverage.

■

Allow inspection and repairs to be per-

formed by a Lexus dealer

●

Lexus technicians are well-trained spe-

cialists and are kept up to date with the

latest service information. They are well

informed about the operations of all sys-

tems on your vehicle.

●

Keep a copy of the repair order. It proves

that the maintenance that has been per-

formed is under warranty coverage. If

any problem should arise while your vehi-

cle is under warranty, your Lexus dealer

will promptly take care of it.

General maintenance should be per-
formed on a daily basis. This can be
done by yourself or by a Lexus dealer.

Scheduled maintenance should be
performed at specified intervals
according to the maintenance sched-
ule.

■

Resetting the message indicating main-

tenance is required

■

Handling of the battery

●

Engine exhaust, some of its constitu-

ents, and a wide variety of automobile

components contain or emit chemicals

known to the State of California to

cause cancer and birth defects and

other reproductive harm. Work in a

well ventilated area.

●

Oils, fuels and fluids contained in vehi-

cles as well as waste produced by

component wear contain or emit

chemicals known to the State of Cali-

fornia to cause cancer and birth

defects or other reproductive harm.

Avoid exposure and wash any affected

area immediately.

●

Battery posts, terminals and related

accessories contain lead and lead

compounds which are known to cause

brain damage. Wash your hands after

handling. (

The OBD system determines that a
problem exists somewhere in the emis-
sion control system. Your vehicle may
not pass the I/M test and may need to
be repaired. Contact your Lexus
dealer to service the vehicle.



When the battery is disconnected
or discharged
Readiness codes that are set during
ordinary 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

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 or the battery.

Fuel and battery fumes are flammable.

■

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. (

tion and skin cancer, so care should be

taken to avoid prolonged and

repeated contact. To remove used

engine oil from your skin, wash thor-

oughly with soap and water.

ground.

Call your Lexus dealer, service station

or auto parts store for information

concerning recycling or disposal.

●

Do not leave used engine oil within the

reach of children.

NOTICE

■

To prevent serious engine damage

Check the oil level on a regular basis.

■

When replacing the engine oil

●

Be careful not to spill engine oil on the

vehicle components.

●

Avoid overfilling, or the engine could

be damaged.

●

■

Coolant selection

Only use “Toyota Super Long Life Coolant”

or a similar high quality ethylene glycol

based non-silicate, non-amine, non-nitrite,

and non-borate coolant with long-life

hybrid organic acid technology.
U.S.A.:

“Toyota Super Long Life Coolant” is a mix-

ture of 50% coolant and 50% deionized

water. (Minimum temperature: -31°F [-

35°C])
Canada:

“Toyota Super Long Life Coolant” is a mix-

ture of 55% coolant and 45% deionized

water. (Minimum temperature: -44°F [-

42°C])
For more details about engine coolant, con-

tact your Lexus dealer.

■

If the coolant level drops within a short

time of replenishing

Visually check the radiator, hoses, engine

coolant reservoir cap, 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 and condenser and
clear away any foreign objects.
If either of the above parts is extremely
dirty or you are not sure of their condi-
tion, have your vehicle inspected by
your Lexus dealer.

WARNING

■

When the engine is hot

Do not remove the engine coolant reser-

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.

WARNING

■

When filling the reservoir

Take care as brake fluid can harm your

hands and eyes and damage painted sur-

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.
