2005 JEEP WRANGLER Owners Manual

RADIO OPERATION AND CELLULAR PHONES
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 “clear” by the repositioning of the
antenna, it is recommended that the radio volume be
turned down or off during cellular phone operation.
CLIMATE CONTROLS
The controls for the heating and ventilation system in this
vehicle consist of three rotary control knobs.
NOTE:For the HVAC to operate efficiently and reduce
the possibility of fog build up on the interior of the
windows, the air exhausters should be kept clear at all
times. The air exhausters are the slots located on the rear
tailgate.
Heater Only — If Equipped
In snowy weather, always clear the air inlet grille at the
base of the windshield before driving your vehicle.

Blower Switch
The blower switch is the rotary knob to the left of the
controls. The blower speed will increase as the knob
is turned clockwise. There are four blower speeds.
NOTE:The blower motor will run until the mode
control knob is turned to the “Off” (“O”) position or the
ignition is turned OFF.
Temperature Control
The temperature control is the center knob located on the
climate controls. It controls the temperature of the air
delivered to the passenger compartment.
You can choose your degree of comfort by rotating the
knob. The coldest setting is to the extreme left (blue
region) and the warmest setting is to the extreme right
(red region).
Mode Selection
The mode selector is the right knob located on the climate
controls. It can be set in any of the following positions:
Off
This position turns off the blower motor. In this
mode, there may be some slight air flow from the
floor outlets, side window outlets, and defrost outlet
located at the base of the windshield.
Panel
Outside air comes from the outlets in the instrument
panel. Each of these outlets can be individually
adjusted to direct the flow of air. Also, a slight amount of
airflow may be noticed at the defrost outlet located at the
base of the windshield.

floor outlets. Also, a slight amount of airflow may
be noticed at the defrost outlet located at the base of the
windshield.

Outside air comes from the floor outlets. Also, a
slight amount of airflow may be noticed at the
defrost outlet located at the base of the windshield.

Recirculation
Select this position when the outside air contains
smoke, odors, high humidity, or if rapid cooling is
desired. This feature allows for recirculation of
interior air only. Air flows through the panel outlets in
this mode. Also, a slight amount of airflow may be
noticed at the defrost outlet located at the base of the
windshield.
Panel
Outside air flows through the air conditioning
system, and then through the outlets located in the
instrument panel. Also, a slight amount of airflow
may be noticed at the defrost outlet located at the base of
the windshield.

Outside air flows through the air conditioning
system, and then through the outlets located in the
instrument panel and those located on the floor. Also, aslight amount of airflow may be noticed at the defrost
outlet located at the base of the windshield.

Defrost
Outside air comes from the windshield outlets
with a small amount being directed through the
floor outlets. Use this setting when necessary to defrost
your windshield.
NOTE:For improved safety, the A/C compressor is
activated when “Mix” or “Defrost” modes are selected.
This is done to assist in drying the air and it will help in
keeping the windshield from fogging.
Operating Tips
Summer Operation
The engine cooling system in air conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. A 50% solution of ethylene
glycol antifreeze coolant in water is recommended.
Winter Operation
The air from the heater system will heat faster in cold
weather if you use lower blower speeds until the engine
warms up. When operating the system during the winter
months, make sure the air intake, located directly in front
of the windshield, is free of ice, slush, snow, or other
obstructions.
Window Fogging
In mild but rainy or humid weather, the windows might
fog on the inside. To clear the fog off all of the windows,
turn the mode control knob to the “Panel” position (with
snowflake). Adjust the temperature control and blower
speed to maintain comfort. Direct the panel outlets
toward the side windows. Interior fogging on the wind-
shield can be quickly removed by selecting the “Defrost”
position.
