CLIMATE CONTROLS
The Air Conditioning and Heating System is designed to
make you comfortable in all types of weather.
Dual-Zone Automatic Temperature Control
The Dual Zone Automatic Temperature Control (ATC)
System automatically maintains the interior comfort level
desired by the driver and front seat passenger. This is
accomplished by using two infrared sensors located in
the center of the instrument panel. The two infrared
sensors independently measure the surface temperature
of the driver and front seat passenger. Based on the
sensor input, the system automatically adjusts the airtemperature, the airflow volume, the airflow distribu-
tion, and amount of inside air recirculation to maintain
front seat occupant comfort, even under changing out-
side weather conditions.
To operate the system, press either theAUTO HIor
AUTO LObuttons. The system now automatically

regulates the heating and air conditioning system includ-
ing blower speed, outlet air temperature, and airflow
distribution through the various outlets within the in-
strument panel. Using theTEMPbuttons, adjust the
temperature you would like the system to maintain.
When the system is set to your comfort level, it is not
necessary to change the settings. You will experience the
greatest efficiency by allowing the system to function
automatically. The system will operate fully automati-
cally in eitherAUTO HIorAUTO LO. TheAUTO
LOsetting will limit the maximum fan speed and should
be used when more quiet operation is desired. Use the
AUTO HIsetting when the quickest cool-down or
warm-up performance is desired.
NOTE:
•It is not necessary to move the temperature settings for
cold or hot vehicles. The system automatically adjusts
the temperature, mode and fan speed to provide
comfort as quickly as possible.
•The temperature can be displayed in U.S. or Metric by
selecting the US/M customer programmable feature.
Refer to the “Electronic Vehicle Information Center-
Customer Programmable Features” in Section 3 of this
manual.
To provide you with maximum comfort in the automatic
mode, during cold start-ups the blower fan will remain
off and “DELAY” will appear in the display until the
engine warms up. An estimate of the time remaining
until the “DELAY” is complete will appear periodically
in the display. However, the fan will engage immediately
if the defrost mode is selected or by pushing the blower
switch and manually adjusting the fan speed.
This feature may be disabled using the following proce-
dure:
•Press and hold the Heated Rear Window and Auto LO
buttons for 5 seconds.

NOTE:While operating inAUTO HIorAUTO LO,
the system will not automatically sense the presence fog,
mist, or ice on the windshield. The defrost button must be
pressed to clear the windshield and side glass.
Depress the “A/C” button to turn on and off the
air conditioning during manual operation only.
Cool dehumidified air comes through the outlets
selected by the Mode Control. To turn off the air condi-
tioning, press the A/C button a second time. The A/C
symbol in the display will turn off.
NOTE:If a fog or mist appears on the windshield or
side glass, press the “A/C” button to engage the com-
pressor or press the defrost button. If a fog or mist on the
windshield or side glass starts to impair visibility, press
the front blower button and increase the fan speed to
maximum.Recirculation Control
When the outside air contains smoke, odors,
high humidity, or if rapid cooling is desired
you may wish to recirculate interior air by
pressing the recirculation button. The recircu-
lation mode should only be used temporarily. The recir-
culate symbol will illuminate in the display when this
button is selected. Push the button a second time to allow
outside air into the vehicle.
NOTE:In cold weather, use of the recirculation mode
may lead to excessive window fogging. The recirculation
mode is not allowed in the Mix and Defrost modes to
improve window clearing operation. Recirculation will
be disabled automatically if these modes are selected.
A/C Recirculation Programming
The recirculation control is programmed to cancel the
recirculation mode when the ignition key is turned OFF
and will reset to the outside air mode when the ignition

Window Fogging
Vehicle windows tend to fog on the inside in mild rainy
or humid weather. To clear the windows, use the A/C
button to reduce the humidity inside the vehicle.
Fogging on the inside of the windshield can be quickly
removed by pressing the defrost button and increasing
the blower speed.
Do not use the Recirculation mode without the A/C
button for long periods as fogging may occur.
Outside Air Intake
Before driving, always make sure the air intake located
directly in front of the windshield is free of obstructions
such as leaves, ice, or snow, which could reduce airflow
and/or plug the water drain tube inside the plenum.
A/C Air Filter
The climate control system filters out dust, pollen and
some odors from the air. Strong odors can not be totally
filtered out. Refer to section 7 “Air Conditioning” for
filter replacement instructions.
Outside Temperature Display
The outside temperature can be shown in the ATC
display by pressing theOUTSIDE TEMPbutton. After
pressing this button, the front seat passenger’s tempera-
ture setting display will be replaced with the current
outside temperature. Press theOUTSIDE TEMPbutton
again or press the passenger’sTEMPbutton to return
the display to the passenger’s temperature setting.

IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate ac-
tion.
•On the highways — Slow down.
•In city traffic — While stopped, put transmission in
neutral, but do not increase engine idle speed.
NOTE:There are steps that you can take to slow down
an impending overheat condition. If your air conditioner
is on, turn it off. The air conditioning system adds heat to
the engine cooling system and turning off the A/C
removes this heat. You can also turn the Temperature
control to maximum heat, the Mode control to floor, and
the fan control to High. This allows the heater core to act
as a supplement to the radiator and aids in removing heat
from the engine cooling system.
CAUTION!
Driving with a hot cooling system could damage
your vehicle. If temperature gauge reads “H”, pull
over and stop the vehicle. Idle the vehicle with the
air conditioner turned off until the pointer drops
back into the normal range. If the pointer remains on
the “H”, turn the engine off immediately, and call for
service.
WHAT TO DO IN EMERGENCIES 263

Air Conditioner Maintenance
For best possible performance, your air conditioner
should be checked and serviced by an Authorized Dealer
at the start of each warm season. This service should
include cleaning of the condenser fins and a system
performance check. Drive belt tension should also be
checked at this time.WARNING!
•Use only refrigerants approved by the manufac-
turer for your air conditioning system. Some un-
approved refrigerants are flammable and can ex-
plode, injuring you. Other unapproved
refrigerants can cause the system to fail, requiring
costly repairs.
•The air conditioning system contains refrigerant
under high pressure. To avoid risk of personal
injury or damage to the system, adding refrigerant
or any repair requiring lines to be disconnected
should be done by an experienced repairman.

Refrigerant Recovery And Recycling
R-134a Air Conditioning Refrigerant is a hydrofluorocar-
bon (HFC) that is endorsed by the Environmental Pro-
tection Agency and is an ozone-saving product. How-
ever, the manufacturer recommends that air conditioning
service be performed by dealers or other service facilities
using recovery and recycling equipment.
NOTE:Air Conditioning systems found to be contami-
nated with A/C System Sealers, Stop Leak Products, Seal
Conditioners, Compressor Oil, or Refrigerants not ap-
proved by the manufacturer, voids the warranty for the
Air Conditioning system.
A/C Air Filter
The filter access door is located under the instrument
panel on the passenger side. To replace the filter slide the
lock toward the rear of the vehicle (unlock position).
Remove the access door and pull the filter downward.When installing a new filter, ensure its proper orienta-
tion. Align the black arrow on the bottom of the filter
frame with the direction of airflow (away from the
blower motor and towards the center of the car).
Refer to the “Maintenance Schedules” section of this
manual for the recommended air conditioning filter
replacement intervals.
Power Steering — Fluid Check
Checking the power steering fluid level at a defined
service interval is not required. The fluid should only be
checked if a leak is suspected, abnormal noises are
apparent, and/or the system is not functioning as antici-
pated. Coordinate inspection efforts through a certified
DaimlerChrysler Dealership.
294 MAINTAINING YOUR VEHICLE

CAUTION!
•When installing the Integrated Power Module
cover, it is important to ensure the cover is prop-
erly positioned and fully latched. Failure to do so
may allow water to get into the Integrated Power
Module, and possibly result in a electrical system
failure.
•When replacing a blown fuse, it is important to
use only a fuse having the correct amperage
rating. The use of a fuse with a rating other than
indicated may result in a dangerous electrical
system overload. If a properly rated fuse contin-
ues to blow, it indicates a problem in the circuit
that must be corrected.
VEHICLE STORAGE
If you are leaving your vehicle dormant for more than 21
days you may want to take steps to protect your battery.
You may:
•Disconnect the negative cable from the battery.
•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
insure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.
