4-2. Maintenance
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 th e emission control system.
■If the malfunction indicator lamp comes on
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.
■ Your vehicle may not pass the I/M test:
●When the battery is disconnected or discharged
Readiness codes that are se t 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 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 prepare the vehicle for re-testing.

If you perform maintenance yourself, be sure to follow the correct
procedures as given in these sections.
ItemsParts and tools
Battery condition ( P. 378)•Warm water
• Baking soda
• Grease
• Conventional wrench
(for terminal clamp bolts)
Brake fluid level ( P. 375)• FMVSS No.116 DOT 3 or SAE
J1703 brake fluid

Maintenance and care
CAUTION
●
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.
● Take care because brake fluid can harm your hands or eyes and damage
painted surfaces.
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.
■ When working near the electric c ooling fans or radiator grille
Vehicles with smart key system: Be sure the “ENGINE START STOP” 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 conditioning is on
and/or the coolant temperature is high. ( P. 374)
Vehicles without smart key system: Be sure the engine switch is OFF. With
the engine switch in the “ON” position, the electric cooling fans may auto-
matically start to run if the air conditioning is on and/or the coolant tempera-
ture is high. ( P. 374)
■ 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
Driving with the air cleaner removed may cause excessive engine wear due
to dirt in the air. Also, a backfire could cause a fire in the engine compart-
ment.

Type B
Green: Good condition
Dark: Charging is necessary.
Have the vehicle inspected by
your Toyota dealer.
Clear or light yellow: Not
working properly. Have the
battery checked by your
Toyota dealer.
■Before recharging
When recharging, the battery produces hydrogen gas which is flammable
and explosive. Therefore, before recharging:
●If recharging with the battery installed on the vehicle, be sure to discon-
nect the ground cable.
● Make sure the power switch on the charger is off when connecting and
disconnecting the charger cables to the battery.
■ After recharging/reconnect ing the battery (vehicles with smart key sys-
tem)
The engine may not start. Follow the procedure below to initialize the sys-
tem.
Shift the shift lever to P.
Open and close any of the doors.
Start the engine. (If the engine does not start first time, repeat the
procedure.)
If the engine will not start even after multiple attempts at the above method,
contact your Toyota dealer.
