5-2. Using the air conditioning system and defogger
HIGHLANDER_U
tioning system is controlled as fol-
lows to prioritize fuel efficiency:
• Engine speed and compressor
operation controlled to restrict
heating/cooling capacity
• Fan speed restricted when auto-
matic mode is selected
● To improve air conditioning perfor-
mance, perform the following
operations:
• Adjust the fan speed
• Turn off Eco drive mode (P.306)
• Turn off Eco air conditioning 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 air conditioning eco mode can
be turned off by pressing the Eco
air conditioning mode switch.
■ When the outside temperature
is low
The dehumidification function may
not operate even when “A/C” is
pressed.
■ Ventilation and air conditioning
odors
● To let fresh air in, set the air condi-
tioning 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
occurring:
• It is recommended that the air
conditioning system be set to out-
side 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 con-
ditioning system is started in auto-
matic mode.
● When parking, the system auto-
matically switches to outside air
mode to encourage better air cir-
culation throughout the vehicle,
helping to reduce odors that occur
when starting the vehicle.
1 Press the automatic mode
switch.
The dehumidification function
begins to operate. Air outlets and
fan speed are automatically
adjusted according to the tempera-
ture setting and humidity.
2 Adjust the temperature set-
ting.
3 To stop the operation, press
the “OFF” switch.
If the fan speed setting or air
flow modes are operated, the
automatic mode indicator goes
off. However, automatic mode
for functions other than that
operated is maintained.
■ Using automatic mode
Fan speed is adjusted automati-
cally 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 the auto-
matic mode switch is pressed.
This function automatically con-
trols the air conditioning airflow
so that priority is given to the
front seats. When the front pas-
senger seat is not occupied, air-
flow may switch to only the
driver’s seat. Unnecessary air
