A high electrical load occurs when
several of the following are on, such
as: headlamps, high beams, rear
window defogger, climate control fan
at high speed, heated seats, engine
cooling fans, trailer loads, and loads
plugged into accessory power
outlets.
EPM works to prevent excessive
discharge of the battery. It does this
by balancing the generator's output
and the vehicle's electrical needs.
It can increase engine idle speed to
generate more power whenever
needed. It can temporarily reduce
the power demands of some
accessories.
Normally, these actions occur in
steps or levels, without being
noticeable. In rare cases at the
highest levels of corrective action,
this action may be noticeable to the
driver. If so, a DIC battery voltage
and charging message displays, it is
recommended that the driver reduce
the electrical loads as much as
possible. SeeBattery Voltage and
Charging Messages 0124 and

C (40 °F). The system is
automatically set to outside air,
unless it is hot outside and
then the air inlet changes to
recirculation mode to help
quickly cool the vehicle. The
recirculation indicator light will
come on.
2. Set the temperature for the driver and passenger.
To find a comfortable setting,
start with a 22 °C (73 °F)
temperature setting and allow
about 20 minutes for the
system to regulate. Use the
driver side or passenger side
temperature control to adjust the temperature setting as
necessary. The system will
remain at the selected setting.
Choosing the warmest or
coolest temperatures does not
cause the vehicle to heat or
cool more quickly.
To avoid blowing cold air in
cold weather, the system
delays turning on the fan until
warm air is available. Turn the
fan knob to override this delay
and select the fan speed.
Temperature Control
The driver and passenger side
temperature controls are used to
adjust the temperature of the air
coming through the system. The
temperature can be adjusted even if
the system is turned off since
outside air still enters the vehicle,
unless the recirculation mode is
selected. See “Recirculation” later in
this section.

The A/C does not work when the
outside temperature is below 4 °C
(40 °F). If A/C is pressed the
indicator flashes three times and
turns off to show that the A/C mode
is not available. If the A/C is on and
the outside temperature drops
below a temperature which is too
cool for air conditioning to be
effective, the A/C indicator turns off
to show that the A/C mode has
been canceled.
On hot days, open the windows
briefly to let hot inside air escape.
This helps reduce the time it takes
for the interior of the vehicle to
cool down.
The air conditioning system
removes moisture from the air, so
water might drip under the vehicle
while idling or after turning off the
engine. This is normal.
@:Press to alternate between
recirculating air inside the vehicle or
pulling in outside air. An indicator
light comes on when recirculation
mode is active. With each ignition
cycle, the recirculation mode is
reset to automatic. When the engine is turned on, outside air or
recirculation is automatically
selected for better performance.
When recirculation is activated, the
air conditioning compressor comes
on and helps to quickly cool the air
inside the vehicle. This mode also
helps to reduce the outside air and
odors that may enter the vehicle.
The recirculation mode cannot be
used with floor, defog, or defrosting
modes. If recirculation is selected in
these modes, the indicator flashes
three times and turns off. While in
recirculation mode the windows can
fog when the weather is cold and
damp. To clear the fog, select either
the defog or defrost mode and
increase the fan speed.

warranty. Do not clear the inside
rear window with sharp objects.
Sensors
The solar sensor in the defrost grille
in the middle of the instrument
panel, monitors the solar heat. Do
not cover the solar sensor or the
system will not work properly.
The interior temperature sensor, on
the instrument panel to the right of
the steering column, measures the
temperature of the air inside the
vehicle.
There is also an exterior
temperature sensor behind the front
grille. This sensor reads the outside
air temperature and helps maintain
the temperature inside the vehicle.
Any cover on the front of the vehicle
could cause a false reading in the
displayed temperature.The climate control system uses the
information from these sensors to
maintain comfort settings by
adjusting the temperature, fan
speed, and air delivery mode. The
system may also supply cooler air to
the side of the vehicle facing the
sun. The recirculation mode will also
be used as needed to maintain cool
outlet temperatures.
