Maintenance and care
Emission inspection and maintenance (I/M)
programs
The OBD system determin es that a problem exists somewhere in the
emission control system. Your vehi cle 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 duri ng 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 Diagnos tics) 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 la mp still remains on after sev-
eral driving trips
If your vehicle does not pass the I/M test

When trouble arises
■SRS warning light
This warning light system monitors the airbag sensor assembly, front impact
sensors, side impact sensors, driver’s seat belt buckle switch, front passen-
ger occupant classification system (ECU and sensors), “AIR BAG ON” indica-
tor, “AIR BAG OFF” indicator, front passenger’s seat belt buckle switch, seat
belt pretensioner assemblies, airbags, interconnecting wiring and power
sources. ( →P. 34)
■ Front passenger detection sensor, passenger seat belt reminder and
warning buzzer
● If luggage is placed on the front passenger seat, the front passenger de\
tec-
tion sensor may cause the warning light to flash and the warning buzzer to
sound even if a passenger is not sitting in the seat.
● If a cushion is placed on the seat, the sensor may not detect a passenger,
and the warning light may not operate properly.
■ Electric power steering system warning light (warning buzzer)
When the battery charge becomes insufficient or the voltage temporarily
drops, the electric power steering system warning light may come on and \
the
warning buzzer may sounds.
■ If the malfunction indicator la mp comes on while driving
First check the following:
● Is the fuel tank empty?
If it is, fill the fuel tank immediately.
● Is the fuel tank cap loose?
If it is, tighten it securely.
The malfunction indicator lamp will go off after several driving trips.
If the malfunction indicator lamp does not go off even after several trips, con-
tact your Toyota dealer as soon as possible.
■
When the tire pressure warning light comes on (vehicles with a tire
pressure warning system)
Check the tire inflation pressure and adjust to the appropriate level. Push-
ing the tire pressure warning reset switch will not turn off the tire pressure
warning light.

3488-1. Specifications
■Recommendation of the use of low emissions gasoline
Gasolines containing oxygenates such as ethers and ethanol, as well as
reformulated gasolines, are available in some cities. These fuels are typically
acceptable for use, providing they meet other fuel requirements.
Toyota recommends these fuels, since the formulations allow for reduced
vehicle emissions.
■ Non-recommendation of the use of blended gasoline
●If you use gasohol in your vehicle, be sure that it has an octane rating no
lower than 87.
● Toyota does not recommend the use of gasoline containing methanol.
■ Non-recommendation of the use of gasoline containing MMT
Some gasoline contains an octane enhancing additive called MMT (Methylcy-
clopentadienyl Manganese Tricarbonyl).
Toyota does not recommend the use of gasoline that contains MMT. If fuel
containing MMT is used, your emission control system may be adversely
affected.
The malfunction indicator lamp on the instrument cluster may come on. If this
happens, contact your Toyota dealer for service. ● Use only gasoline containing up to 15%
ethanol.
DO NOT use any flex-fuel or gasoline
that could contain more than 15% etha-
nol, including from any pump labeled
E30, E50, E85 (which are only some
examples of fuel containing more than
15% ethanol).
DO NOT use gasoline
containing more than
15% ethanol.
(30% ethanol)
(50% ethanol)
(85% ethanol)
