air conditioning JEEP WRANGLER 2010 Owners Manual

NOTE:If your air conditioning performance seems
lower than expected, check the front of the A/C con-
denser: located in front of the radiator, for an accumula-
tion of dirt or insects. Clean with a gentle water spray
from behind the radiator and through the condenser.
Fabric front fascia protectors may reduce air flow to the
condenser, reducing air conditioning performance.
Recirculation Control
Press this button to choose be-
tween outside air intake or recir-
culation of the air inside the ve-
hicle. A light will illuminate when
you are in “Recirculation” mode.
Only use the “Recirculation”
mode to temporarily block out
any outside odors, smoke, or dust
and to cool the interior rapidly
upon initial start up in very hot or humid weather. NOTE:
Continuous use of the “Recirculation” mode
may make the inside air stuffy and window fogging may
occur. Extended use of this mode is not recommended.
In cold or damp weather, the use of the “Recirculation”
mode will cause windows to fog on the inside because of
moisture buildup inside the vehicle. For maximum de-
fogging, select the Outside Air position.
NOTE: The “Recirculation” mode will not operate in the
floor, mix or defrost modes.

Operating Tips
Window Fogging
Windows will fog on the inside when the humidity inside
the vehicle is high. This often occurs in mild or cool
temperatures when it’s rainy or humid. In most cases
turning on the air-conditioning (pressing the snowflake
button) will clear the fog. Adjust the temperature control,
air direction 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
Air conditioned vehicles must be protected with a high
quality antifreeze coolant during summer to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50 %
concentration is recommended. Refer to Fluids and
Genuine Parts in “Maintaining Your Vehicle” for the
proper coolant type.
324 UNDERSTANDING YOUR INSTRUMENT PANEL

The automatic transmission fluid and filter should be
changed if you REGULARLY tow a trailer for more than
45 minutes of continuous operation. Refer to “Mainte-
nance Schedule” for the proper maintenance intervals.
NOTE:Check the automatic transmission fluid level
before towing.
O/D Off
To reduce the potential for automatic transmission over-
heating, select the “O/D OFF” feature when driving in
hilly areas or shift the transmission to DRIVE position 2
on more severe grades. Refer to “Automatic Transmis-
sion” in “Starting and Operating” for further
information.
Electronic Speed Control – If Equipped

Do not use in hilly terrain or with heavy loads.
When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
434 STARTING AND OPERATING

Refrigerant Recovery and Recycling
R-134a Air Conditioning Refrigerant is a hydrofluoro-
carbon (HFC) that is endorsed by the Environmental
Protection Agency (EPA) and is an ozone-saving product.
However, the manufacturer recommends that air condi-
tioning service be performed by authorized dealers or
other service facilities using recovery and recycling
equipment.
Body Lubrication
Locks and all body pivot points, including such items as
seat tracks, door hinge pivot points and rollers, liftgate,
tailgate, sliding doors and hood hinges, should be lubri-
cated periodically with a lithium-based grease, such as
MOPARSpray White Lube or equivalent, to assure
quiet, easy operation and to protect against rust and
wear. Prior to the application of any lubricant, the parts
concerned should be wiped clean to remove dust and
grit; after lubricating, excess oil and grease should be
removed. Particular attention should also be given to hood latching components to ensure proper function.
When performing other underhood services, the hood
latch, release mechanism and safety catch should be
cleaned and lubricated.
The external lock cylinders should be lubricated twice a
year, preferably in the Fall and Spring. Apply a small
amount of a high quality lubricant, such as MOPAR
Lock Cylinder Lubricant or equivalent, directly into the
lock cylinder.Windshield Wiper Blades
Clean the rubber edges of the wiper blades and the
windshield periodically with a sponge or soft cloth and a
mild non-abrasive cleaner. This will remove accumula-
tions of salt or road film.
Operation of the wipers on dry glass for long periods
may cause deterioration of the wiper blades. Always use
washer fluid when using the wipers to remove salt or dirt
from a dry windshield. Avoid using the wiper blades to
