Emission inspection and maintenance (I/M) programs
Some states have vehicle emission inspection programs which
include OBD (On Board Diagnostics) checks. The OBD system moni-
tors the operation of the emission control system.
■ If the malfunction i ndicator lamp comes on
The OBD system determines that a problem exists somewhere
in the emission control system. Y our vehicle may not pass the I/
M test and may need to be repaired. Contact your Toyota dealer
to service the vehicle.
■ Your vehicle may not pass the I/M test:
●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 t ank cap is loose
The malfunction indicator lamp comes on as a temporary mal-
function and your vehicle may not pass the I/M test.
■ When the malfunction indicator lamp goes off after several
driving trips
The error code in the OBD system will not be cleared unless the
vehicle is driven 40 or more times.
■ If your vehicle does not pass the I/M test
Contact your Toyota dealer to pr epare the vehicle for re-testing.

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 or ra gs, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel or t he bat-
tery. Fuel and battery fumes are flammable.
● Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
■ When working near the electric cooling fans or radiator grille
Vehicles without a smart key system: Be sure the engine switch is off. With
the engine switch in the “ON” position, the electric cooling fa ns may auto-
matically start to run if the air conditioning is on and/or the coolant tempera-
ture is high. ( P. 337)
Vehicles with a smart key system: Be sure the “ENGINE START STO P”
switch is off. With the “ENGINE START STOP” switch in IGNITION ON
mode, the electric cooling fans may automatically start to run if the air condi-
tioning is on and/or the coolant temperature is high. ( P. 337)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the 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.

Battery
Check the battery as follows.
■ Battery exterior
Make sure that the battery terminals are not corroded and that
there are no loose connections, cracks, or loose clamps.
Hold-down clamp
Te r m i n a l s
■ Checking battery fluid
Check that the level is between
“UPPER LEVEL” and “LOWER
LEVEL”.
“UPPER LEVEL”
“LOWER LEVEL”
If the fluid level is at or below
“LOWER LEVEL”, add distilled
water.

■Adding distilled water
Remove the vent plug.
Add distilled water.
If the “UPPER LEVEL” line cannot be seen, check the fluid level by
looking directly at the cell.
Put the vent plug back on and close securely.
Low O.K.
■Before recharging
When recharging, the battery produces hydrogen gas which is fla mmable
and explosive. Therefore, before recharging:
● If recharging with the battery installed on the vehicle, be sur e to discon-
nect the ground cable.
● Make sure the power switch on the charger is off when connectin g and
disconnecting the charger cables to the battery.

Maintenance and care
■
After recharging/reconnecting the battery (vehicles with a smar t key
system)
● Unlocking the doors using the smart key system may not be possi ble
immediately after reconnecting the battery. If this happens, use the wire-
less remote control or the mechanical key to lock/unlock the do ors.
● Start the engine with the “ENGINE START STOP” switch in ACCES-
SORY mode. The engine may not start with the “ENGINE START STOP ”
switch turned off. However, the engine will operate normally from the sec-
ond attempt.
● The “ENGINE START STOP” switch mode is recorded by the vehicle. If
the battery is reconnected, the vehicle will return the “ENGINE START
STOP” switch mode to the status it was in before the battery was discon-
nected. Make sure to turn off the engine before disconnect the battery.
Take extra care when connecting the battery if the “ENGINE STAR T
STOP” switch mode prior to discharge is unknown.
If the engine will not start even after multiple attempts, cont act your Toyota
dealer.
