Automatic climate control system (if equipped) NOTE Operate the automatic climate control system when the engine is
running. When the engine coolant is cold, for instance in cold weather, the
air flows through the windshield defroster outlets and the blowerruns at the lowest speed to prevent cold air from blowing directly
against the driver and front passenger. In the “AUTO” mode, if the air temperature in the passenger
compartment is cooled down to the specified temperature, the air
conditioner compressor stops automatically. For efficient defogging
or dehumidifying in cold weather, press the “A/C” switch on.
Even when cooling is not necessary, setting the temperature
much lower than the current outlet air temperature turns on the airconditioner compressor automatically and the “A/C” indicator light
on the control panel comes on.
The automatic c limate c ontrol system automatic ally c ontrols outlet air
temp erature, fan sp eed , air flow d istrib ution air-i nlet c ontrol, and air c on-
d itioner c omp ressor op eration. It ac tivates when th e “AUTO ” switc h is
p ressed , and is used in c onjunc tion with the Temp er ature c ontrol d ial to
maintain a c onstant, c omfortab le c limate within the p asseng er c omp art-
ment.
The temp erature c an b e set within a rang e of 65 – 85 F (18 – 32 C).
NOTE
The temperature is shown in units of Fahrenheit for US model and in Centigrade for Canadian model.

AUTO mode operation:
The Automatic Climate Control system automatic ally c ontrols the air
temp erature of the p asseng er c omp artment in the AUT O mod e. When
the “AUTO ” switc h is p ressed , the ind ic ator lig ht “AUTO ” on the c on-
trol p anel c omes on. In this state, outlet air temp erature, fan sp eed , air
flow d istrib ution, air-inlet c ontrol, and air c ond i tioner c omp ressor op -
eration are automatic ally c ontrolled . ECON (economy) mode:
When you p ress the “AUTO ” switc h while the system is in the AUTO
mod e, it selec ts the ECON (ec onomy) mod e, turning o n the

” ind ic ator lig ht. In the ECON mod e, the c omp ressor runs to
b e thrifty with energ y c onsump tion. Interior wind ow s tend to fog in this
energ y-saving op eration. It is therefore rec ommend e d that the AUTO
mod e b e used only in hig h humid ity c ond itions. Manual mode operation:
When the Automatic Climate Control system is op erat ing in the AUTO
mod e, p ressing the “
”, “”, “MODE ”, “A/C ” or
“
” switc h shifts the op eration into the “MANUAL ” mod e and the
ind ic ator lig ht “AUTO ” on the c ontrol p anel will g o out.
When the “

switc h is p ressed , the c orresp ond ing func tion c an b e c ontrolled ind e-
p end ently, while automatic c ontrol of the other fun c tions are main-

To c hang e the system b ac k to the AUTO mod e, p ress t he “AUTO ”
switc h. n OFF switch
The Automatic Climate Control system turns off (the air c ond itioner
c omp ressor and fan turn off) when the “OFF ” switc h is p ressed .
When the “OFF ” switc h is p ressed , the outsid e air introd uc tion mo d e
( “
” p osition) is automatic ally selec ted .
NOTE Setting the light switch to the “p ” or “ a ” position causes the
illuminating icons on the display panel to dim. When traveling with the lights on in gloomy daylight or in twilight, press the OFFswitch for 1 second or longer if you feel it is too hard to identify
the icons clearly. The brightness comes back to normal. n OUT.TEMP switch
To c hec k the outsid e air temp erature, p ush the “OUT.TEMP ” switc h.
The outsid e air temp erature will b e d isp layed for f ive sec ond s, and
then the d isp lay automatic ally c hang es b ac k to the insid e air temp er-
ature.
The d isp lay c hang es over from the insid e air temp er ature to the out-
sid e air temp erature as its normal ind ic ation if yo u keep the switc h
p ressed for more than 2 sec ond s.

4-14NOTE
You can check the outside air temperature even when the Au-
tomatic Climate Control is off. (The ignition switch should be in the “ON” position.)
In the following cases, the display can indicate a higher tem-
perature than the actual outside air temperature: – In direct sunlight
– When the vehicle is parked for a long period of time with the
engine kept running.– During stop and go driving

HB5023BB
NOTE A setting of about 77 F (25 C) throughout the year is recom-
mended. The temperature setting remains even after the ignition switch
is turned to the “OFF”. However, if the battery cables are discon-
nected, the temperature will be set to 77 F (25 C) automatically.
Set d esired temp erature b y turning the temp erature c ontrol d ial; turn
the d ial c loc kwise to raise the temp erature setting and turn it c ounter-
c loc kwise to lower it.
The temp erature c an b e set in inc rements of 1 F within a rang e of 65
– 85 F for US mod els and in inc rements of 0.5 C within a rang e of 18
– 32 C for Canad ian mod els.
Even when q uic k c ooling or warming is nec essary, yo u d o not have to
c hang e the temp erature setting . The Automatic Clima te Control sys-
tem op erates at maximum p erformanc e until the air i n the p asseng er

Temperature sensors
This Automatic Climate Control system emp loys the s everal sensors.
These are very d elic ate p arts. Therefore, if these sensors are d am-
ag ed , it is p ossib le that the Automatic Climate Con trol system will not
p rop erly c ontrol the air temp erature in the p asseng er c omp artment.
To p revent p ossib le d amag e to the sensors, p lease o b serve the fol-
lowing :
–Do not allow anything to imp ac t the sensors.
– Be c areful not to let water c ontac t the sensors.
– Do not c over the sensors.
The sensors are found at the following loc ations: – Sun-load sensor (b esid e the wind shield d efroster g r ille)
– In-vehic le temp erature sensor (b esid e the temp eratu re c ontrol
d ial.)
– Amb ient sensor (at the b ac ksid e of the front g rille )
