Under certain conditions, the cellular phone being On in
your vehicle can cause erratic or noisy performance from
your radio. This condition may be lessened or eliminated
by relocating the cellular phone antenna. This condition
is not harmful to the radio. If your radio performance
does not satisfactorily ªclearº by the repositioning of the
antenna, it is recommended that the radio volume be
turned down or off during cellular phone operation.

Air Conditioning
The controls for the heating/air conditioning and venti-
lation system in this vehicle consist of a series of rotary
knobs. These comfort controls can be set to obtain desired
interior conditions.The instrument panel features four dual-vane airflow
registers. Two registers are located on the outer ends of
the instrument panel and two are located in the center of
the instrument panel. These registers can be closed to
partially block airflow.
Press this button to turn on and off the air condi-
tioning. Cool dehumidified air comes through the
outlets selected by the mode selector. Press the button a
second time to turn off the air conditioning. The button
includes an LED that illuminates when compressor op-
eration is selected.

LO AUTO position should be used for front seat occu-
pants only. The HI AUTO position should be used when
more air flow is desired, or when rear seat occupants are
present. Dial in the temperature you would like the
system to maintain by rotating the driver's or passenger's
control knob. Once the comfort level is selected the
system will maintain that level automatically using the
heating system. Should the desired comfort level require
air conditioning, the system will automatically make the
adjustment.
You will experience the greatest efficiency by simply
allowing the system to function automatically. Selecting
the OFF position on the fan control stops the system
completely and closes the outside air intake.
72ÉF (22ÉC) is the recommended setting for maximum
comfort for the average person, however, this may vary.
NOTE:The temperature setting can be adjusted at any
time without affecting automatic control operation.The air conditioning in this system is automatic.
Pressing this button while in AUTO mode will
cause an audible beep and the LED will flash three
times and remain off. This indicates that the system is in
AUTO and requesting the air conditioning is not neces-
sary.
The system will automatically control recircu-
lation. However, pressing this button will tem-
porarily put the system in recirculation mode
(ten minutes). This can be used when outside
conditions such as smoke, odors, dust, or high humidity
are present. This will cause an audible beep, and the LED
will illuminate. After ten minutes the system will return
to normal AUTO mode function and the LED will turn
off.

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 ªHº, 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 ªHº, turn the engine off immediately, and call for
service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call a service center if your
vehicle overheats. If you decide to look under the
hood yourself, see Section 7, Maintenance, of this
manual. Follow the warnings under the Cooling
System Pressure Cap paragraph.
JACKING AND TIRE CHANGING
WARNING!
Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off
the road to avoid the danger of being hit when
operating the jack or changing the wheel.
WHAT TO DO IN EMERGENCIES 265

CAUTION!
²It is essential when replacing the cables on the
battery that the positive cable is attached to the
positive post and the negative cable is attached to
the negative post. Battery posts are marked posi-
tive (+) and negative (-) and identified on the
battery case. Cable clamps should be tight on the
terminal posts and free of corrosion.
²If a ªfast chargerº is used while battery is in
vehicle, disconnect both vehicle battery cables
before connecting the charger to battery. Do not
use a ªfast chargerº to provide starting voltage.
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 performance
test. Drive belt tension should also be checked at this
time.
WARNING!
²Use only refrigerants and compressor lubricants
approved by the manufacturer for your air condi-
tioning system. Some unapproved refrigerants are
flammable and can explode, injuring you. Other
unapproved refrigerants or lubricants can cause
the system to fail, requiring costly repairs.
²The 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:NOTE: Air Conditioning systems found to be
contaminated with A/C System Sealers, Stop Leak Prod-
ucts, Seal Conditioners, Compressor Oil, or Refrigerants
not approved by the manufacturer, voids the warranty
for the Air Conditioning system.
A/C Air Filter
The filter is located in the fresh air inlet under the hood,
behind a removable panel in the cowl on the passenger
side of the vehicle, next to the windshield wipers. When
installing a new filter, ensure its proper orientation. To
replace the filter remove the access door in the cowl
screen by pressing the retaining clips. Slide the lid on the
filter adapter forward and down and remove used filter.
Install new filter with arrows pointing in the direction of
airflow, which is toward the rear of the vehicle (text and
arrows on the filter indicate this).
Refer to the ªMaintenance Schedulesº section of this
manual for the recommended air conditioning filter
replacement intervals.
Power Steering Ð 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.9
WARNING!
Fluid level should be checked on a level surface and
with the engine off to prevent injury from moving
parts and to insure accurate fluid level reading. Do
not overfill. Use only manufacturers recommended
power steering fluid.
If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from all
surfaces. Refer to Recommended Fluids, Lubricants, and
Genuine Parts for correct fluid type.

If you are leaving your vehicle dormant for more than 21
days you may want to take steps to protect your battery.
You may:
²Disconnect the negative cable from the battery.
²Anytime 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.
