In order to prevent the windshield from fogging up when the outside air is
cold, the following may occur:
• Outside air mode does not switch to recirculated air mode.
• The air conditioning system operates automatically.
• The operation cancels after 1 minute.
In rainy weather, the windows may fog up. Press .
Outside temperature display
In the following situations, the correct outside temperature may not be dis-
played, or the display may take longer than normal to change.
When stopped, or driving at low speeds (less than 25 km/h [16 mph])
When the outside temperature has changed suddenly (at the entrance/
exit of a garage, tunnel, etc.)
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 capacity
Fan speed restricted when automatic mode is selected
To improve air conditioning performance, perform the following operations:
Adjust the fan speed and temperature
Turn off Eco drive mode (P. 226)
Customize the air conditioning control of Eco drive mode. (P. 554)

CAUTION
Burns
Use caution when seating the following persons in a seat with the seat
heater on to avoid the possibility of burns:
• Babies, small children, the elderly, the sick and the physically chal-
lenged
• Persons with sensitive skin
• Persons who are fatigued
• Persons who have taken alcohol or drugs that induce sleep (sleeping
drugs, cold remedies, etc.)
Do not cover the seat with anything when using the seat heater.
Using the seat heater with a blanket or cushion increases the temperature
of the seat and may lead to overheating.
Do not use the seat heater more than necessary. Doing so may cause
minor burns or overheating.
NOTICE
To prevent seat heater damage
Do not put heavy objects that have an uneven surface on the seat and do
not stick sharp objects (needles, nails, etc.) into the seat.
To prevent 12-volt battery discharge
Turn the seat heaters off when the hybrid system is off.
