6-2. Maintenance

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 Toyota 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 vehi-
cle is driven 40 or more times.

Contact your Toyota 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 sev-
eral driving trips

If your vehicle does not pass the I/M test

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

●

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 bat-
tery. Fuel and battery fumes are flammable.

●

Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.

■

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.

Hood

Pull the hood lock release lever.

The hood will pop up slightly.

Pull up the auxiliary catch lever
and lift the hood.

Hold the hood open by inserting
the supporting rod into the slot.

Release the lock from the inside of the vehicle to open the hood.

418

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 with the support rod up could cause the hood to bend.

With the engine at operating temperature and turned off, check the oil
level on the dipstick.

■

Checking the engine oil

Park the vehicle on level ground. After warming up the engine
and turning it off, wait more than 5 minutes for the oil to drain
back into the bottom of the engine.
Holding a rag under the end, pull the dipstick out.

Wipe the dipstick clean.
Reinsert the dipstick fully.
Holding a rag under the end,

■

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.

Make sure to check the oil type and prepare the items needed
before adding oil.

Remove the oil filler cap by turning it counterclockwise.
Add engine oil slowly, checking the dipstick.
Install the oil filler cap by turning it clockwise.

■

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, when towing, or
when driving while accelerating 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 disorders such as inflammation and skin cancer, so care
should be taken to avoid prolonged 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 Toyota 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.

●

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

●

Be sure the engine oil filler cap is properly tightened.

Engine coolant

424

■

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% deion-
ized water. (Minimum temperature: -31



F [-35



C])

Canada:
“Toyota Super Long Life Coolant” is a mixture of 55% coolant and 45% deion-
ized water. (Minimum temperature: -44



F [-42



C])

For more details about coolant, contact your Toyota 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 Toyota dealer test the cap and check for
leaks in the cooling system.

WARNING

■

When the engine is hot

Do not remove the radiator cap and engine coolant reservoir cap. (



P. 534)

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 cooling. 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.

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 condition, have your vehicle inspected by your Toyota dealer.

■

Checking fluid level

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