Climate Controls 7-3
If the airflow seems low when the
fan speed is at the highest setting,
the passenger compartment air filter
might need to be replaced. For more
information, see Passenger
Compartment Air Filter
on
page 76
and Scheduled
Maintenance on page 103.
H G (Air Delivery Mode Control):
Press the buttons to change the
direction of the airflow. The current
mode appears in the display screen.
Changing the mode cancels the
automatic air delivery. Press AUTO
to return to automatic operation.
The outboard air outlets always
receive some airflow in every mode,
except defrost.
To change the current mode, select
one of the following:
Y (Vent): Air is directed to the
instrument panel outlets.
\ (Bi-Level): Air is divided
between the instrument panel
outlets and the floor outlets. In
automatic operation, cooler air is
directed to the upper outlets and
warmer air to the floor outlets.
[ (Floor): Air is directed to the
floor outlets, with some air directed
to the windshield and outboard
outlets.
- (Defog): This mode clears the
windows of fog or moisture. Air is
directed to the windshield, floor and
side window outlets. When this
mode is selected, the system turns
off recirculation and runs the
air-conditioning compressor unless
the outside temperature is at or
below freezing. If recirculation is
selected while in defog mode, it is
cancelled after 10 minutes.
0 (Defrost): This mode clears the
windshield of fog or frost more
quickly. Air is directed to the
windshield, with some air directed to
the side windows. In this mode, the
system automatically turns off
recirculation and runs the
air-conditioning compressor, unless
the outside temperature is at or
below freezing.
This mode can also cause the fan
speed and air temperature to
increase.
# (Air Conditioning): Press to
turn the air conditioning system on
or off and override the automatic
system. When in AUTO, the air
conditioning compressor comes on
automatically, as needed.
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.
M (Recirculation): Press to turn
on recirculation. An indicator light
comes on. Air is recirculated inside
the vehicle. It helps to quickly cool
the air inside the vehicle or prevent
outside air and odors from entering.
Press the auto button to have the
system select the best air delivery
mode for the temperature setting.
