Opening the fuel tank cap
●Turn the engine switch off and ensure that all the doors and windows are
closed.
●Confirm the type of fuel.
■Fuel types

P. 555
■Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your vehicle has a fuel tank opening that only accom-
modates the special nozzle on unleaded fuel pumps.
Perform the following steps to open the fuel tank cap:
Before refueling the vehicle
WA R N I N G
■When refueling the vehicle
Observe the following precautions while refu eling the vehicle. Failure to do so may
result in death or serious injury.
●After exiting the vehicle and before openin g the fuel door, touch an unpainted metal
surface to discharge any static electricity. It is important to discharge static electricity
before refueling because sparks resulting fr om static electricity can cause fuel vapors
to ignite while refueling.
●Always hold the grips on th e fuel tank cap and turn it slowly to remove it.
A whooshing sound may be heard when the fuel tank cap is loosened. Wait until the
sound cannot be heard before fully removing the cap. In hot weather, pressurized fuel
may spray out the filler neck and cause injury.
●Do not allow anyone that has not discharged static electricity from their body to come
close to an open fuel tank.
●Do not inhale vaporized fuel.
Fuel contains substances th at are harmful if inhaled.
●Do not smoke while refueling the vehicle.
Doing so may cause the fuel to ignite and cause a fire.
●Do not return to the vehicle or touch any person or object that is statically charged.
This may cause static electricity to build up, resulting in a possible ignition hazard.
■When refueling
Observe the following precautions to prevent fuel overflowing from the fuel tank:
●Securely insert the fuel nozzle into the fuel filler neck.
●Stop filling the tank after the fuel nozzle automatically clicks off.
●Do not top off the fuel tank.

face.

Interior features
■When the outside temperature exceeds 75°F (24°C) and the air conditioning system
is on
●In order to reduce the air conditioning po wer consumption, the air conditioning system
may switch to recirculated air mode automa tically. This may also reduce fuel consump-
tion.
●Recirculated air mode is selected as a default mode when the engine switch is turned
on.
●It is possible to switch to outside air mode at any time by pressing .
■Automatic mode for air intake control
In automatic mode, the system detects exhaust gas and other pollutants and automati-
cally switches between outside air and recirculated air modes.
When the dehumidification function is off, and the fan is operating, turning automatic
mode on will activate the dehumidification function.
■Operation of the air conditioning system in Eco drive mode
In the Eco drive mode, the air conditioning system is controlled as follows to prioritize
fuel efficiency:
●Engine speed and compressor operation controlled to restrict heating/cooling capac-
ity
●Fan speed restricted when automatic mode is selected
To improve air conditioning performance, perform the following operations:
●Turn off eco air conditioning mode
●Adjust the fan speed
●Turn off Eco drive mode ( P. 2 9 3 )
■Eco air conditioning mode
When Eco drive mode is selected using the drive mode select switch, eco air condition-
ing mode turns on.
When a drive mode other than Eco drive mode is selected, eco air conditioning mode
may turn off.
■When the S-FLOW mode operates
If air flows to the driver’s seat only, the temperature setting for the front passenger’s seat
is not displayed.
■When the outside temperature is low
The dehumidification function may not operat e even when “A/C” on the option control
screen is selected.
■Ventilation and air conditioning odors
●To let fresh air in, set the air conditio ning system to the outside air mode.
●During use, various odors from inside and outside the vehicle may enter into and accu-
mulate in the air conditioning system. This may then cause odor to be emitted from the
vents.
●To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air mode prior to turning the vehicle off.
• The start timing of the blower may be dela yed for a short period of time immediately
after the air conditioning system is started in automatic mode.
