TOYOTA PRIUS 2005 2.G Owners Manual

181
The automatic air conditioning automat-
ically maintains the set temperature.
This air conditioning features automatic
fan speed and air flow control which auto-
matically selects the most suitable fan
speed and air flow to control the tempera-
ture. The hybrid system must be in the
“IG−ON” mode.
CLIMATE: Push this button to display
switches for automatic air conditioning
controls.
NOTICE
To prevent the battery from being dis-
charged, do not leave the air condi-
tioning on longer than necessary
when the hybrid system is not operat-
ing.

1. Touch the “AUTO” switch.
The indicator located in the instrument
cluster will come on.
Air conditioning is turned on if not oper-
ated.
Air flow quantity, switching of the diffus-
ers, and switching of the air intake be-
tween RECIRCULATED AIR and OUTSIDE
AIR are automatically adjusted. The opera-
tion status is shown by each indicator.
However, if the RECIRCULATED AIR
mode is selected manually, automatic con-
trol of air intake cannot be activated. When one of the manual control buttons
is depressed while operating in automatic
mode, the mode relevant to the depressed
button is set. Other conditions continue to
be adjusted automatically. However, oper-
ating the air flow outlets or fan speed will
turn off the automatic control.

SETTING OPERATION—manual control
When one of the manual control
switches is touched while operating in
automatic mode, the mode relevant to
the touched switch is set. Other condi-
tions continue to be adjusted automati-
cally.If manual air flow selection is desired—
27p113a
The outlets from which air is delivered
can be selected manually by touching the
switch. The function of each mode is as
follows:
1. Panel— Air flows mainly from the
instrument panel vents.
2. Bilevel— Air flows from both the floor
vents and the instrument panel vents.
3. Floor— Air flows mainly from the floor
vents.
4. Floor/Windshield— Air flows mainly
from the floor vents and windshield
vents.
The selected mode is highlighted in green. If quick heating or cooling is desired—
27p112a
Touch the “TEMP” switch and hold it until
the maximum figure or minimum figure ap-
pears.

184
If manual fan speed control is desired—
27p114a
1. Fan speed at low
2. Fan speed at high
The fan speed can be set to your desired
speed by touching the appropriate air flow
control switch. The higher the fan speed
is, the more air is delivered. Touching the
“OFF” switch turns off the fan.
To remove exterior windshield frost, use the
high speed setting.
The selected mode is highlighted in green.
If manual switching of air intake is de-
sired—
27p115a
The air intake control switch is used to
switch the air intake between the OUT-
SIDE AIR mode and RECIRCULATED AIR
mode.
With the switch in the OUTSIDE AIR
mode, the system will take fresh outside
air into the vehicle.
If quick circulation of cooled air is de-
sired, touch the air intake control switch
for RECIRCULATED AIR.
The indicator will come on in the instru-
ment cluster while the RECIRCULATED
AIR mode is selected.If recirculated air is used during heating,
the windows will fog up more easily.
If the hybrid system is turned off in the
OUTSIDE AIR mode, the automatic control
of the air intake is activated when the
hybrid system is turned on again.
2way air intake control
To improve fuel economy, OUTSIDE AIR
mode control changes when the air in-
take selector is set in OUTSIDE AIR on
the following conditions:
When the maximum heating is needed
with the air flow in “Floor” or “Floor/
Windshield”, fresh air flows in the up-
per compartment, while air is recircu-
lated in the lower compartment.
When cooling is needed, both fresh
and recirculate modes turns on.

185
If manual onoff of the air conditioning
is desired—
Touch the “A/C” switch to turn the air
conditioning on and touch it again to turn
the air conditioning off.
If the system is used for ventilation, heat-
ing in dry weather or removing frost or
exterior fog on the windshield, turn the air
conditioning off once it is no longer re-
quired. This will improve fuel economy.
The air conditioning can be used for year−
round automatic temperature control in-
cluding cooling and dehumidifying opera-
tion.
27p116a
To remove interior fog on the wind-
shield—
Touch the front windshield switch.
To remove frost or exterior fog on the
windshield— 1. Touch the upper side of the tempera- ture control switch until maximum fig-
ure appears on the temperature dis-
play.
2. Touch the front windshield switch.
3. Push the “HI” of the air flow control switch to obtain a maximum air flow.
4. Leave the air conditioning on −off button
off. When the front windshield switch is
touched, the air conditioning is set to op-
erate and the OUTSIDE AIR mode is set.
If you touch the front windshield switch
once again while in the FRONT WIND-
SHIELD mode, the mode then returns to
the last mode used.
The indicator will come on in the instru-
ment cluster while the FRONT WIND-
SHIELD mode is on.
CAUTION
Do not use the front windshield
switch during cooled air operation in
extremely humid weather. The differ-
ence between the temperature of the
outside air and that of the windshield
could cause the outer surface of the
windshield to fog up blocking your
vision.

The light sensor is located on the driv-
er ’s side edge of the instrument panel.
If you put anything on this area or
cover the area, the sensor function
may be adversely affected.
To cool off your Toyota after it has
been parked in the hot sun, drive with
the windows open for a few minutes.
This vents the hot air, allowing the air
conditioning to cool the interior more
quickly.
Make sure the air intake grilles in front
of the windshield are not blocked (by
leaves or snow, for example).
On humid days, do not blow cold air
on the windshield. The windshield could
fog up because of the difference in air
temperature on the inside and outside
of the windshield.
Keep the area under the front seats
clear to allow air to circulate through-
out the vehicle.
On cold days, set the fan speed to
high for a minute to help clear the
intake ducts of snow or moisture. This
can reduce the amount of fogging on
the windows.
When driving on dusty roads, close all
windows. If dust thrown up by the ve-
hicle is still drawn into the vehicle after
closing the windows, it is recommended
that the air intake selector be set to
OUTSIDE AIR and the fan speed se-
lector to any setting except “OFF”.
If following another vehicle on a dusty
road, or driving in windy and dusty
conditions, it is recommended that the
air intake selector be temporarily set to
RECIRCULATE, which will close off the
outside passage and prevent outside
air and dust from entering the vehicle
interior.

The air conditioning filter information
label is placed on the left side of the
glove box as shown and indicates that
a filter has been installed.
The air conditioning filter prevents dust
from entering the vehicle through the air
conditioning vent.

82p006b
The air conditioning filter is set behind
the glove box.The air conditioning filter may clog af-
ter long use. The filter may need to be
replaced if the air flow of the air condi-
tioning and heater experiences extreme
reductions in operating efficiency, or if
the windows begin to fog up easily.
To maintain the air conditioning efficiency,
inspect and replace the air conditioning
filter according to the maintenance sched-
ule. In dusty areas or areas with heavy
traffic flow, such as inner city or desert
areas, early replacement may be required.
(For scheduled maintenance information,
please refer to the “Owner ’s Manual Sup-
plement/Scheduled Maintenance”.)

tioning with the air filter removed
may cause deteriorated dustproof per-
formance and then affect air condi-
tioning performance.
