AUTO (Automatic Climate Control): Press the AUTO
button when you want the system to automatically
maintain a set temperature. When the system is set for
automatic operation, air will come from the floor ducts,
instrument panel outlets or windshield outlets depending
on the temperature inside the vehicle, the outside
temperature and the sun load. Sun and temperature
sensors automatically adjust the air temperature, the
airflow direction and the fan speed to maintain your
comfort setting. The system may supply cooler air to the
side of the vehicle toward the sun. Be careful not to put
anything over the sensors on top of the dash.
To find your preferred temperature setting, start with the
system in AUTO mode and the temperature set at 75
F
(24
C). Give the vehicle about 20 minutes to stabilize,
and adjust your the temperature setting, if necessary,
using the TEMP button. The display will show the
selected temperature, fan speed and airflow direction for
a few seconds, and then it will display the outside
temperature. If you choose a temperature setting of 60
F
(15
C), the system will remain at the maximum cooling
setting and fan speed. If you choose a temperature
setting of 90
F (33
C), the system will remain at the
maximum heat setting and fan speed. Choosing either
maximum setting will not cause the system to heat or
cool any faster.In cold weather, the system will delay turning the fan
on high, to avoid blowing cold air into the vehicle. The
length of the delay depends on the engine coolant
temperature and the outside temperature. Pressing the
FAN, AIR FLOW or FRONT buttons will override
this delay, turn off the AUTO setting and change the
fan speed.
Air Conditioning
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for your
vehicle to cool down. Then keep your windows closed
for the air conditioner to work its best.
On very hot days, the automatic system will enter the
recirculation mode and the temperature door will be
positioned at the full cold position for maximum cooling
for as long as necessary to reach the set temperature.
You can choose the extreme temperature setting of
60
F (15
C), but the system will not cool any faster.

Main and Auxiliary Instrument Panel Fuse Blocks
The main and auxiliary instrument panel fuse blocks are
located on the passenger's side of the vehicle, under the
instrument panel. Lamps, connectors and the HVAC
duct temperature sensors may need to be disconnected
and removed to allow access to these fuse blocks.
Remove the hush panel on the passenger's side to reveal
the fuses by performing the following steps:
1. Remove the two screws located along the front edge
of the panel.
2. Lower the hush panel.
3. Remove the fuse block cover.
4. Place the wide end of the fuse puller over the plastic
end of the fuse.
5. Squeeze the ends over the fuse and pull it out.
When finished, reinstall the fuse block cover and the
hush panel. Reinstall lamps, connectors and HVAC duct
temperature sensors if they were removed.Main Instrument Panel Fuse Block
