Automutic Ekctronic
Climate Control (OPTION)
With this system, you can control the
ventilation, heating
and air conditioning
in your vehicle, or you can use the
automatic setting.
Your vehicle also has
the flow-through ventilation system
described later
in this section.
The digital screen displays the outside
temperature, the inside temperature
setting, and the fan speed.
If the inside
temperature is changed,
or if the system
is changed from
OFF to any mode, the
inside temperature setting will be
displayed for several seconds before the
outside temperature is again displayed.
The
air conditioner compressor operates
in all air conditioning positions, and in
(@ (Defrost) when the outside
temperature is above freezing.
When
the air conditioner is on, you may
sometimes notice slight changes in your
vehicle's engine speed and power. This
is normal, because the Automatic
EIectronic Climate Control system
is
designed to cycle the compressor on
and off to keep the desired cooling and
to
help your vehicle's fuel economy.
TEMP SET: This control sets the
interior temperature you want. Press
V to lower the inside temperature
setting; press
A to raise the setting.
The temperature
you set will be
displayed on the digital screen.
Once you set the temperature you want,
the system will try to maintain this temperature,
whether
you are using the
heating
or the cooling controls.
However, if you set the temperature for
60°F (16°C) or 90°F (3Z°C), the fan will
stay on 3p udess you select a
different speed.
Your Automatic Electronic Climate
Control system
has three sensors. The
sun load sensor on top of the dashboard
detects increased interior temperature
caused by sunlight.
To keep you
comfortable, it reduces the interior
temperature
by as much as 5°F (3°C)
below the setting on the digital screen.
The outside air temperature sensor,
located on the right
side of the upper
radiator support
in the grille opening,
reads the outside temperature.
This is
what you usually see on the display.

The outside ternperatufe sensor reading
is filtered (to minimize false readings)
as follows:
If- the outside temperature decreases,

(such as when stopped in traffic), the
displayed temperature will not update
until one
of the following eonditiom

Vehicle speed is above 25 mph
Vehicle speed 'is above 45 mph
Updates will occur continuously as long
as the vehicle speed remains above
25 mph (40 Wh).
zf the ignition is turned off for more
than three hours, the current outside air
tempepature when the vehicle is restarted
will be stored in the system immediately.

you use this setting, the controller
chooses the fan speed based on the
input signals.
In the AUTO mode
during hot weather (after the vehicle
has not been running for a period of
time) the-fan speed will be
low when
the vehicle is initially
started. This

initial low fan speed is used to purge
the vehicle of hot interior air. In the

reaches
an adequate temperature to
provide heat.

the automatic fan speed. To increase
fan speed, press the A button and

Air Conditioning System
If a light above a button flashes when
you turn
on the ignition, it may indicate
an electrical problem with your air
conditioning system. The flashing will
continue for one minute, then go but. It
means you should have your system
checked
and serviced if needed.
It may
also mean the rekigerant level is
too low in your air conditioner system.
The. light will still flash after rebigerant
is added. This means your system will
not cool the air until it is reset.
