Some states have vehicle emission in-
spection programs which include OBD
(On−Board Diagnostics) che cks.
The OBD system monitors the operation
of the emission control system. When the
OBD system determines that a problem
exists somewhere in the emission control
system, the malfunction indicator lamp
comes on. In this case, your vehicle may
not pass the I/M test and need to be
repaired. Contact your Toyota dealer to
service the vehicle.
Even if the malfunction indicator lamp
does not come on, your vehicle may not
pass the I/M test as readiness codes
have not been set in the OBD system.
Readiness codes are automatically set
during ordinary driving. However, when the
battery is disconnected or run down, the
codes are erased. Also, depending on
your driving habits, the codes may not be
completely set.
Also, if the malfunction indicator lamp had
come on recently due to temporary mal-
function such as a loose fuel tank cap,
your vehicle may not pass the I/M test. The malfunction indicator lamp will go off
after taking several driving trips, but the
error code in the OBD system will not be
cleared unless about 40 trips or more are
taken.
If your vehicle does not pass the I/M test
even the malfunction indicator lamp does
not come on, contact your Toyota dealer
to prepare the vehicle for re
−testing.

CAUTION
When the engine is running, keep
hands, clothing, and tools away
from the moving fan and engine
drive belts. (Removing rings,
watches, and ties is advisable.)
Right after driving, the engine
compartment—the engine, radiator,
exhaust manifold, power steering
fluid reservoir and spark plug
boots, etc.—will be hot. So be care-
ful not to touch them. Oil, fluids
and spark plugs may also be hot.
If the engine is hot, do not remove
the radiator cap or loosen the drain
plugs to prevent burning yourself.
Do not leave anything that may
burn easily, such as paper or rags,
in the engine compartment.
Do not smoke, cause sparks or al-
low open flames around fuel or the
battery. Their fumes are flammable.
Do not get under your vehicle with
just the body jack supporting it. Al-
ways use automotive jack stands or
other solid supports.
Be sure that the ignition is off if
you work near the electric cooling
fans or radiator grille. With the
ignition on, the electric cooling fans
will automatically start to run if the
engine coolant temperature is high
and/or the air conditioning is on.
Use eye protection whenever you
work on or under your vehicle
where you may be exposed to flying
or falling material, fluid spray, etc.
Used engine oil contains potentially
harmful contaminants which may
cause skin disorders such as in-
flammation or skin cancer, so care
should be taken to avoid prolonged
and repeated contact with it. To re-
move used engine oil from your
skin, wash thoroughly with soap
and water.
Do not leave used oil within the
reach of children.
Dispose of used oil and filter only
in a safe and acceptable manner.
Do not dispose of used oil and fil-
ter in household trash, in sewers or
onto the ground. Call your dealer or
a service station for information
concerning recycling or disposal.
Be extremely cautious when work-
ing on the battery. It contains poi-
sonous and corrosive sulfuric acid.
NOTICE
Remember that battery and ignition
cable carry high currents or volt-
ages. Be careful of accidentally
causing a short circuit.
 Add only “Toyota Super Long Life
Coolant” or similar high quality eth-
ylene glycol based nonsilicate,
nonamine, nonnitrite, and nonbo-
rate coolant with longlife hybrid
organic acid technology to fill the
radiator. “Toyota Super Long Life
Coolant” is a mixture of 50% cool-
ant and 50% deionized water (for
the U.S.A.) or 55% coolant and 45%
deionized water (for Canada).

Tire pressure gauge
INSPECTION AND ADJUSTMENT
PROCEDURE 1. Remove the tire valve cap.
2. Press the tip of the tire pressure gauge to the tire valve.
3. Read the pressure using the grad- uations of the gauge.
4. In case the tire inflation pressure
is not within the prescribed range,
insert the compressed air from the
valve. In case of applying too
much air, press the center of the
valve and release the air to adjust. 5. After completing the tire inflation
pressure measurement and ad-
justment, apply soapy water to the
valve and check for leakage.
6. Install the tire valve cap.
If a gauge and air pump are not avail-
able, have your vehicle checked by
your Toyota dealer.
CAUTION
Be sure to reinstall the tire valve
caps. Without the valve caps, dirt
or moisture could get into the
valve core and cause air leakage.
If the caps have been lost, have
new ones put on as soon as pos-
sible.
Incorrect tire infl ation pressure may
waste fuel, reduce the comfort of driv-
ing, reduce tire life and make your ve-
hicle less safe to drive.
If a tire frequently needs refilling,
have it checked by your Toyota deal-
er.
CAUTION
Keep your tires properly inflated.
Otherwise, the following condi-
tions may occur and cause an ac-
cident resulting in death or seri-
ous injuries.
Low tire pressure ( underinfla-
tion)—
 Excessive wear
 Uneven wear
 Poor handling
 Possibility of blowouts from an
overheated tire
 Poor sealing of the tire bead
 Wheel deformation and/or tire
separation
 A greater possibility of tire
damage from road hazards
