5-2. Using the air conditioning system and defogger
defog the windshield effectively.
●
If you turn "A/C" off, the windows
may fog up more easily.
●
The windows may fog up if the
recirculated 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 recommended 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 recom-
mended in preventing dirty air
from entering the vehicle interior
and helping to cool the vehicle
when the outside air temperature
is high.
●
Outside/recirculated air mode may
automatically switch depending on
the temperature setting or the
inside temperature.
■
Operation of the air condition-
ing system in Eco drive mode
●
In Eco drive mode, the air condi-
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)
■
When the outside temperature
is low
The dehumidification function may
not operate even when the "A/C"
switch is pressed.
■
Ventilation and air conditioning
odors
●
To let fresh air in, set the air condi-
HIGHLANDER_U
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.
■
Air conditioning system opera-
tions when the engine is
stopped due to the Stop & Start
system (vehicles with Stop &
Start system)
When the engine is stopped due to
Stop & Start system operations, the
automatic air conditioning cooling,
heating and dehumidification func-
tions turn off and the fan speed is
decreased according to the outside
temperature etc. or air blowing
stops. To stop the air conditioning
system from turning off, press the
Stop & Start cancel switch and
refrain from using the Stop & Start
system.
■
When the windshield is fogged
up and the engine is stopped
due to the Stop & Start system
(vehicles with Stop & Start sys-
