Operating Tips - Jeep 2013 Wrangler Owner's Manual

NOTE:
• When the ignition switch is turned to the
LOCK position, the recirculation feature
will be cancelled.
• In cold weather, use of the Recirculation
mode may lead to excessive window fog-
ging. The Recirculation mode is not al-
lowed in the defrost mode in order to
improve window clearing. Recirculation
will be disabled automatically if this mode
is selected.
• Extended use of recirculation may cause
the windows to fog. If the interior of the
windows begins to fog, press the Recir-
culation button to return to outside air.
Some temp/humidity
cause captured interior air to condense
on windows and hamper visibility. For
this reason, the system will not allow
Recirculation to be selected while in de-
frost mode. Attempting to use the recircu-
lation while in this mode will cause the
LED in the control button to blink and
then turn off.

• Most of the time, when in Automatic Op-
eration, you can temporarily put the sys-
tem into Recirculation Mode by pressing
the Recirculation button. However, under
certain conditions, while in Automatic
Mode, the system is blowing air out the
defrost vents. When these conditions are
present, and the Recirculation button is
pressed, the indicator will flash and then
turn off. This tells you that you are unable
to go into Recirculation Mode at this time.
If you would like the system to go into
Recirculation Mode, you must first move
the Mode knob to Panel, Panel/Bi-Level
and then press the Recirculation button.
This feature reduces the possibility of
window fogging.

Operating Tips

NOTE:
Refer to the chart at the end of this section
for suggested control settings for various
weather conditions.
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 over-
heating. A solution of 50% ethylene glycol anti-
freeze coolant and 50% water is recommended.
Refer to "Maintenance Procedures" in "Main-
taining Your Vehicle" for proper coolant selec-
tion.
Winter Operation
Use of the air Recirculation Mode during winter
months is not recommended because it may
cause window fogging.
