Driving
After refueling, turn the fuel tank
cap until you hear a click. Once
the cap is released, it will turn
slightly in the opposite direction.
Closing the fuel tank cap
WARNING
■When replacing the fuel tank cap

Interior features
■Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high.
Turning on will dehumidify the air from the outlets and defog the
windshield effectively.
● If you turn off, the windows may fog up more easily.
● The windows may fog up if the recirculated air mode is used.
■ When driving on dusty roads
Close all windows. If dust thrown up by the vehicle is still drawn into the vehi-
cle after closing the windows, it is recommended that the air intake mode be
set to outside air mode and the fan speed to any setting except off.
■ Outside/recirculated air mode
●Setting to the recirculated air mode temporarily is recommended in prevent-
ing dirty air from entering the vehicle interior and helping to cool the vehicle
when the outside air temperature is high.
● Outside/recirculated air mode may automatically switch dependin g on the
temperature setting or the inside temperature.
■ Fresh air intake system while parking
When parking, the system automatically switches to outside air mode to
encourage better air circulation throughout the vehicle, helpin g to reduce
odors that occur when starting the vehicle.
■ Operation of the air conditioning system in the air conditionin g eco
mode
● In the air conditioning eco mode, the air conditioning system i s controlled as
follows to prioritize fuel efficiency:
• Engine speed and compressor operation controlled to restrict h eating/
cooling capacity
• Fan speed restricted when automatic mode is selected
● To improve air conditioning performance, perform the following operations:
• Adjust the fan speed
• Adjust the temperature setting
• Turn off the air conditioning eco mode
● When the driving mode is set to Eco driving mode, the air condi tioning eco
mode will be turned on automatically. Even in this case, the ai r conditioning
eco mode can be turned off by pressing . ( P. 342)
■ When the outside tempera ture falls to nearly 32F (0 C)
The dehumidification function may not operate even when is pressed.

Maintenance and care
Emission inspection and maintenance (I/M)
programs
The OBD system determines that a problem exists somewhere in th e
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 12-volt 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 tan k cap is loose
The malfunction indicator lamp comes on indicating a temporary
malfunction and your vehicle m ay not pass the I/M test.
The error code in th e OBD system will not be cleared unless the vehi-
cle is driven 40 or more times.
Contact your Toyota dea ler to prepare the vehicle for re-testin g.
Some states have vehicle emission inspection programs which
include OBD (On Board Diagnostics) checks. The OBD system
monitors the operation of t he 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

6-3. Do-it-yourself maintenance
Tire valve
Tire pressure gauge
Remove the tire valve cap.
Press the tip of the tire pressure gauge onto the tire valve.
Read the pressure using the gauge gradations.
If the tire inflation pressure is not at the recommended level, adjust
the pressure.
If you add too much air, press the center of the valve to defla te.
After completing the tire inflation pressure measurement and
adjustment, apply soapy water to the valve and check for leakage.
Put the tire valve cap back on.
■Tire inflation pressure check interval
You should check tire inflation p ressure every two weeks, or at least once
a month.
Do not forget to check the spare.
■Effects of incorrect tire inflation pressure
Driving with incorrec t tire inflation pressure may result in th e following:
●Reduced fuel economy
●Reduced driving comfort and poor handling
●Reduced tire life due to wear
●Reduced safety
●Damage to the drive train
If a tire needs frequent inflating , have it checked by your Toyota dealer.

5947-2. Steps to take in an emergency
PRIUS_OM_OM47F01U_(U)
■SRS warning light
This warning light system monitors the airbag sensor assembly, front impact
sensors, side impact sensors (front door), side impact sensors (front), side
impact sensors (rear), driver’s seat belt buckle switch, front passenger occu-
pant classification system (ECU and sensors), “AIR BAG ON” indi cator light,
“AIR BAG OFF” indicator light, front passenger’s seat belt buck le switch, seat
belt pretensioners, airbags, interconnecting wiring and power s ources.
( P. 35)
■ Front passenger detection sensor, seat belt reminder and warnin g
buzzer
● If luggage is placed on the front passenger seat, the front pas senger detec-
tion sensor may cause the warning light to flash and the warnin g 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 wa rning light (warning buzzer)
When the 12-volt battery charge becomes insufficient or the vol tage tempo-
rarily drops, the electric power steering system warning light may come on
and the warning buzzer may sound.
■ If the malfunction indicator lamp 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 drivin g trips.
If the malfunction indicator lamp does not go off even after several trips, con-
tact your Toyota dealer as soon as possible.
