5-1. Using the air conditioning system and defogger
Interior features
windshield effectively.
●If you turn “A/C” off, the windows may fog up more easily.
●The windows may fog up if the recir-culated air mode is used.
■When driving on dusty roads
Close all windows. If dust thrown up by the vehicle is still drawn into the vehicle after closing the windows, it is recom-
mended 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 pre-
venting dirty air from entering the vehicle interior and helping to cool the vehicle when the outside air tempera-
ture is high.
●Outside/recirculated air mode may
automatically switch depending on the temperature setting or the inside tem-perature.
■Operation of the air conditioning
system in Eco drive mode
●In Eco drive mode, the air conditioning
system is controlled as follows to pri- oritize fuel efficiency:• Engine speed and compressor opera-
tion controlled to restrict heating/cool- ing capacity• Fan speed restricted when automatic
mode is selected
●To improve air conditioning perfor-
mance, perform the following opera- tions:• Adjust the fan speed
• Turn off Eco drive mode ( P.275)
●Even when the drive mode is set to
Eco drive mode, the air conditioning eco mode can be turned off by press-ing the “FAST/ECO” switch. ( P.290)
■When the outside temperature falls
to nearly 0°C (32°F)
The dehumidification function may not operate even when “A/C” switch is
pressed.
■Ventilation and air conditioning
odors
●To let fresh air in, set the air condition-
ing system to the outside air mode.
●During use, various odors from inside
and outside the vehicle may enter into and accumulate in the air conditioning system. This may then cause odor to
be emitted from the vents.
●To reduce potential odors from occur-
ring: • It is recommended that the air condi-tioning system be set to outside air
mode prior to turning the vehicle off. • The start timing of the blower may be delayed for a short period of time
immediately after the air conditioning system is started in automatic mode.
●When parking, the system automati-cally switches to outside air mode to encourage better air circulation
throughout the vehicle, helping to reduce odors that occur when starting the vehicle.

■Customization
Some functions can be customized. ( P.431)
WARNING
■To prevent the windshield from fogging up
Do not use the windshield defogger
switch during cool air operation in extremely humid weather. The differ-ence between the temperature of the
outside air and that of the windshield can cause the outer surface of the windshield to fog up, blocking your
vision.
■When the outside rear view mir-
ror defoggers are operating
Do not touch the outside rear view mirror surfaces, as they can become
very hot and burn you.

6-3. Do-it-yourself maintenance
The 12-volt battery is located in the
right-hand side of the rear seats.
1 Remove the screws.
2 Remove the clips from the
claws.
3 Slide the tabs out of the
notches.
■Before recharging
When recharging, the 12-volt battery produces hydrogen gas which is flam-mable and explosive. Therefore,
observe the following precautions before recharging:
●If recharging with the 12-volt battery installed on the vehicle, be sure to dis-connect the ground cable.
●Make sure the power switch on the charger is off when connecting and
disconnecting the charger cables to the 12-volt battery.
■After recharging/reconnecting the 12-volt battery (vehicles with a
smart entry & start system)
●Unlocking the doors using the smart
entry & start system may not be possi- ble immediately after reconnecting the 12-volt battery. If this happens, use
the wireless remote control or the mechanical key to lock/unlock the doors.
●Start the hybrid system with the power switch in ACC. The hybrid system
may not start with the power switch turned off. However, the hybrid sys-tem will operate normally from the
second attempt.
●The power switch mode is recorded
by the vehicle. If the 12-volt battery is reconnected, the vehicle will return the power switch mode to the status it
was in before the 12-volt battery was disconnected. Make sure to turn off the power before disconnecting the
12-volt battery. Take extra care when connecting the 12-volt battery if the power switch mode prior to discharge
is unknown.
If the system will not start even after multiple attempts, contact any autho-
rized Toyota retailer or Toyota autho- rized repairer, or any reliable repairer.
