System Status messages displays in the EVIC:
•
System OK
• System Warnings Displayed (will display all
currently active System Warnings)
• Tire Pressure Monitor System (shows the
current pressure of all four road tires). For
additional information, refer to “Tire Pressure
Monitor System” in “Starting And Operating”.Tire Pressure Display
173

NOTE:
•Tires heat up during normal driving con-
ditions. Heat will cause the tire pressure
to increase from 2 to 6 psi (14 to 41 kPa)
during normal driving conditions. Refer to
“Tires-General Information/Tire Inflation
Pressures” in “Starting And Operating”
for additional information.
• Your system can be set to display pres-
sure units in PSI, kPa, or BAR.
Keyless Enter-N-Go Display —
If Equipped
When the ENGINE START/STOP button is
pressed to change ignition switch positions, the
Keyless Enter-N-Go icon momentarily appears
in the lower right corner of the EVIC display
showing the new ignition switch position.
Refer to “Keyless Enter-N-Go” in “Starting And
Operating” for more information. NOTE:
Under certain conditions, the display may
be superseded by another display of higher
priority. But when the ignition switch posi-
tion is changed, the display always re-
appears.
Compass / Temperature DisplayThe compass readings indicate the direction
the vehicle is facing. The EVIC will display one
of eight compass readings and the outside
temperature.
NOTE:
The system will display the last known out-
side temperature when starting the vehicle
and may need to be driven several minutes
before the updated temperature is dis-
played. Engine temperature can also affect
the displayed temperature, therefore tem-
perature readings are not updated when the
vehicle is not moving.Automatic Compass Calibration
This compass is self-calibrating, which elimi-
nates the need to manually reset the compass.
When the vehicle is new, the compass may
appear erratic and the EVIC will display CAL
until the compass is calibrated. You may also
calibrate the compass by completing one or
more 360–degree turns (in an area free from
large metal or metallic objects) until the CAL
indicator displayed in the EVIC turns off. The
compass will now function normally.
NOTE:
A good calibration requires a level surface
and an environment free from large metallic
objects such as buildings, bridges, under-
ground cables, railroad tracks, etc.

ton is pressed and the mode control is set
to panel or panel / floor.
• The A/C can be deselected manually with-
out disturbing the mode control selection.
• When the ignition switch is turned to the
LOCK position or the ignition switch
START/STOP button is cycled to OFF, the
recirculation feature will be cancelled.
Air Conditioning Control Press this button to en-
gage the Air Condition-
ing. A light will illumi-
nate when the Air
Conditioning System is
engaged. Rotating the
dial left into the blue
area of the scale indi-
cates cooler tempera-
tures while rotating right
into the red area indicates warmer tempera-
tures.
NOTE:
The air conditioning compressor will not
engage until the engine has been running
for about 10 seconds. •
MAX A/C
For maximum cooling use the A/C and recircu-
lation buttons at the same time.
• ECONOMY MODE
If economy mode is desired, press the A/C
button to turn OFF the indicator light and the
A/C compressor. Then, move the temperature
control to the desired temperature.
Dual-Zone Automatic Temperature
Control (ATC) — If Equipped
• The Automatic Temperature Control (ATC)
allows both driver and front passenger seat
occupants to select individual comfort set-
tings.
• When occupants in the vehicle select an
Auto mode operation, Auto blower operation
is set by using a push button on the control
unit and a comfort temperature setting by
using the temperature up and down buttons.
• The system provides set-and-forget opera-
tion for optimum comfort and convenience.
• The system can be controlled manually, if
desired. The ATC system automatically maintains the
interior comfort level desired by the driver and
passenger.
1. A/C Button
Press and release to change the current Air
Conditioning (A/C) setting, the indicator illumi-
nates when A/C is ON. Performing this function
will cause the ATC to switch into manual mode.
2. Recirculation Control Button
Press and release to change the current set-
ting, the indicator illuminates when ON.

2. Next, adjust the temperature you would like
the system to maintain by adjusting the driver
and front passenger temperature control but-
tons. Once the desired temperature is dis-
played, the system will achieve and automati-
cally maintain that comfort level.
3. When the system is set up for your comfort
level, it is not necessary to change the settings.
You will experience the greatest efficiency by
simply allowing the system to function auto-
matically.
NOTE:
•It is not necessary to move the tempera-
ture settings for cold or hot vehicles. The
system automatically adjusts the tem-
perature, mode and fan speed to provide
comfort as quickly as possible.
• The temperature can be displayed in U.S.
or Metric units by selecting the US/M
customer-programmable feature. Refer to
the “Electronic Vehicle Information Cen-
ter (EVIC) — Customer-Programmable
Features (SETUP)” in this section of the
manual. To provide you with maximum comfort in the
Automatic mode, during cold start-ups the
blower fan will remain on low until the engine
warms up. The blower will increase in speed
and transition into Auto mode.
Manual Operation
This system offers a full complement of manual
override features.
NOTE:
Each of these features operate indepen-
dently from each other. If any one feature is
controlled manually, temperature control
will continue to operate automatically.
There are seven fixed
blower speeds. Use
the outer dial control
to regulate the amount
of air forced through
the system in any
mode you select. The
blower speed in-
creases as you move
the control clockwise
and decreases when you move the control
counter-clockwise. The blower fan speed can be set to any fixed
speed by adjusting the blower control outer
dial. The fan will now operate at a fixed speed
until additional speeds are selected. This al-
lows the front occupants to control the volume
of air circulated in the vehicle and cancel the
Auto mode.
The operator can also select the direction of the
airflow by selecting one of the following posi-
tions.
Panel Mode
Air comes from the outlets in the instru-
ment panel. Each of these outlets can be
individually adjusted to direct the flow of
air. The air vanes of the center outlets and
outboard outlets can be moved up and down or
side to side to regulate airflow direction. There
is a shut off wheel located below the air vanes
to shut off or adjust the amount of airflow from
these outlets.
Bi-Level Mode Air comes from the instrument panel
outlets, floor outlets and defrost outlets.

Operating Tips
Window Fogging
Windows will fog on the inside when the humid-
ity inside the vehicle is high. This often occurs
in mild or cool temperatures when it’s rainy or
humid. In most cases, turning the air condition-
ing (pressing the A/C button) on will clear the
fog. Adjust the temperature control, air direc-
tion, and blower speed to maintain comfort.
As the temperature gets colder, it may be
necessary to direct air onto the windshield.
Adjust the temperature control and blower
speed to maintain comfort. Higher blower
speeds will reduce fogging. Interior fogging on
the windshield can be quickly removed by
selecting the DEFROST mode.Regular cleaning of the inside of the windows
with a non-filming cleaning solution (vinegar
and water works very well) will help prevent
contaminates (cigarette smoke, perfumes, etc.)
from sticking to the windows. Contaminates
increase the rate of window fogging.
Summer Operation
NOTE:
In some cases during high temperature
trailer tow operation the Air Conditioning
system performance may be reduced. This
is to help protect the engine from overheat-
ing during the high load condition.
Your air conditioning system is also equipped
with an automatic recirculation system. When
the system senses a heavy load or high heat
conditions, it may use partial Recirculation A/C
mode to provide additional comfort.Winter Operation
When operating the system during the winter
months, make sure the air intake, located di-
rectly in front of the windshield, is free of ice,
slush, snow, or other obstructions.
Vacation Storage
Anytime you store your vehicle, or keep it out of
service (i.e. vacation) for two weeks or more,
run the air conditioning system at idle for about
five minutes in the fresh air and high blower
setting. This will ensure adequate system lubri-
cation to minimize the possibility of compressor
damage when the system is started again.
