7-2. Maintenance

Main

Emission inspection and maintenance (I/M) programs

The OBD system determines that a problem exists somewhere in the emission
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 12-volt 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 com-
pletely 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.

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

If the malfunction indicator lamp comes on

Your vehicle may not pass the I/M test in the following situations:

When the malfunction indicator lamp still remains on after several driv-
ing trips

If your vehicle does not pass the I/M test

If you perform maintenance by yourself, be sure to follow the correct proce-
dure as given in these sections.

WARNING

The engine compartment contains many mechanisms and fluids that may move suddenly,

become hot, or become electrically energized. To avoid death or serious injury, observe

the following precautions.

■

When working on the engine compartment

●

Make sure that the indicator on the power switch and the “READY” indicator are

both off.

●

Keep hands, clothing and tools away from the moving fan.

●

Be careful not to touch the engine, power control unit, 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 flamma-

ble.

■

When working near the electric cooling fans or radiator grille
Be sure the power switch is off.

With the power switch in ON mode, the electric cooling fans may automatically start to

run if the air conditioning is on and/or the coolant temperature is high. (

■

Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from getting in

your eyes.

NOTICE

■

If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear due to dirt

in the air.

481

Main

WARNING

■

Pre-driving check
Check that the hood is fully closed and locked.

If the hood is not locked properly, it may open while the vehicle is in motion and cause

an accident, which may result in death or serious injury.

■

After installing the support rod into the slot
Make sure the rod supports the hood securely from falling down on to your head or

body.

NOTICE

■

When closing the hood
Be sure to return the support rod to its clip before closing the hood. Closing the hood

without returning the support rod properly could cause the hood to bend.

Adding engine oil
If the oil level is below or near the
low level mark, add engine oil of the
same type as that already in the

■

Engine oil consumption
A certain amount of engine oil will be consumed while driving. In the following situations,

oil consumption may increase, and engine oil may need to be refilled in between oil

maintenance intervals.

●

When the engine is new, for example directly after purchasing the vehicle or after

replacing the engine

●

If low quality oil or oil of an inappropriate viscosity is used

●

When driving at high engine speeds or with a heavy load, or when driving while accel-

erating or decelerating frequently

●

When leaving the engine idling for a long time, or when driving frequently through

heavy traffic

WARNING

■

Used engine oil

●

Used engine oil contains potentially harmful contaminants which may cause skin dis-

orders such as inflammation and skin cancer, so care should be taken to avoid pro-

longed and repeated contact. To remove used engine oil from your skin, wash

thoroughly with soap and water.

●

Dispose of used oil and filters only in a safe and acceptable manner. Do not dispose of

used oil and filters in household trash, in sewers or onto the ground. Call your Lexus

dealer, service station or auto parts store for information concerning recycling or dis-

posal.

●

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.

●

Check the oil level on the dipstick every time you refill the vehicle.

●

Be sure the engine oil filler cap is properly tightened.

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 mixture of 50% coolant and 50% deionized water.

(Minimum temperature: -31

F [-35C])

Canada:

“Toyota Super Long Life Coolant” is a mixture of 55% coolant and 45% deionized water.

(Minimum temperature: -44

F [-42C])

For more details about coolant, contact your Lexus dealer.

■

If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine/power control unit 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.

WARNING

■

When the hybrid system is hot
Do not remove the engine/power control unit coolant reservoir caps.

The cooling system may be under pressure 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 cool-

ing. Be sure to read the antifreeze or coolant label.

■

If you spill coolant
Be sure to wash it off with water to prevent it from damaging parts or paint.

489

Main

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.

■

Checking fluid level
The brake fluid level should be
between the “MAX” and “MIN” lines
on the tank.

■

Adding fluid
Make sure to check the fluid type and prepare the necessary item.

■

Brake fluid can absorb moisture from the air
Excess moisture in the brake fluid can cause a dangerous loss of braking efficiency. Use

only newly opened brake fluid.

Radiator and condenser

WARNING

■

When the hybrid system is hot
Do not touch the radiator or condenser as they may be hot and cause serious injuries,

such as burns.

■

When the electric cooling fans are operating
Do not touch the engine compartment.

The electric cooling fans may keep rotating for about 3 minutes even after the power

switch is off.

With the power switch in ON mode, the electric cooling fans may automatically start to

run if the air conditioning is on and/or the coolant temperature is high. Be sure the

power switch is off when working near the electric cooling fans or radiator grille.
