242 3-1. Using the air conditioning system and defogger
■Operation of the air conditio ning system in Eco drive mode
In Eco drive mode, the air conditioning system is controlled as follows to pri-
oritize fuel efficiency:
● Heating/cooling capacity is restricted.
● Outside/recirculated air mode may automatically switch depending on
the temperature setting or the inside temperature.
● Fan speed restricted when automatic mode is selected
To improve air conditioning performance, perform the following operations:
● Adjust the fan speed or the temperature setting
● Turn off Eco drive mode
■ Using automatic mode
Fan speed is adjusted automatically according to the temperature setting
and the ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow
immediately after is pressed.
■ 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.

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, and check that the
indicator is off.
