2017 JEEP GRAND CHEROKEE air conditioning

IconDescription
Mix Mode
Mix Mode
Air is directed through the floor, defrost, and side window demister outlets. This setting works best in cold or snowy con-
ditions that require extra heat to the windshield. This setting is good for maintaining comfort while reducing moisture on
the windshield.
Climate Control OFF Button
This button turns the Climate Control System off.
CAUTION!
Failure to follow these cautions can cause
damage to the heating elements:
•
Usecarewhenwashingtheinsideofthe
rear window. Do not use abrasive window
cleaners on the interior surface of the
window. Use a soft cloth and a mild wash-
ing solution, wiping parallel to the heating
elements. Labels can be peeled off after
soaking with warm water.
• Do not use scrapers, sharp instru- ments, or abrasive window cleaners on
the interior surface of the window.
• Keep all objects a safe distance from
the window.
Climate Control Functions
A/C (Air Conditioning)
The Air Conditioning (A/C) button allows the
operator to manually activate or deactivate
the air conditioning system. When the air
conditioning system is turned on, cool dehu-
midified air will flow through the outlets into
the cabin. For improved fuel economy, press
the A/C button to turn off the air conditioning
and manually adjust the blower and airflow
mode settings. Also, make sure to select only
Panel, Bi-Level or Floor modes. NOTE:
• If fog or mist appears on the windshield or
side glass, select Defrost mode and in-
crease blower speed if needed.
• If your air conditioning performance seems lower than expected, check the
front of the A/C condenser (located in front
of the radiator), for an accumulation of dirt
or insects. Clean with a gentle water spray
from the front of the radiator and through
the condenser.

warms up. The blower will increase in speed
and transition into Auto mode.
Manual Operation Override
This system offers a full complement of
manual override features. The AUTO symbol
in the front ATC display will be turned off
when the system is being used in the manual
mode.
NOTE:
The system will not automatically sense the
presence of fog, mist or ice on the wind-
shield. DEFROST mode must be manually
selected to clear the windshield and side
glass.
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 must be protected
with a high-quality antifreeze coolant to pro-
vide proper corrosion protection and to pro-
tect against engine overheating. OAT coolant
(conforming to MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and de-
froster performance, make sure the engine
cooling system is functioning properly and
the proper amount, type, and concentration
of coolant is used. Use of the air Recircula-
tion mode during Winter months is not rec-
ommended, because it may cause window
fogging.
Vacation/Storage
Before 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 fresh air with the
blower setting on high. This will ensure ad-
equate system lubrication to minimize the
possibility of compressor damage when the
system is started again.
Window Fogging
Vehicle windows tend to fog on the inside in
mild, rainy and/or humid weather. To clear
the windows, select Defrost or Mix mode and
increase the front blower speed. Do not use
the Recirculation mode without A/C for long
periods, as fogging may occur.
Outside Air Intake
Make sure the air intake, located directly in
front of the windshield, is free of obstructions
such as leaves. Leaves collected in the air
intake may reduce airflow, and if they enter
the plenum, they could plug the water drains.
In winter months, make sure the air intake is
clear of ice, slush, and snow.
Cabin Air Filter
The climate control system filters out dust
and pollen from the air. Contact your autho-
rized dealer to service your cabin air filter,
and to have it replaced when needed.

Air Conditioner Maintenance
For best possible performance, your air con-
ditioner 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!
• Use only refrigerants and compressorlubricants approved by the manufac-
turer for your air conditioning system.
Some unapproved refrigerants are flam-
mable and can explode, injuring you.
Other unapproved refrigerants or lubri-
cants can cause the system to fail, re-
quiring costly repairs. Refer to Warranty
WARNING!
Information Book, for further warranty
information.
• The air conditioning system contains re-
frigerant 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 tech-
nician.
CAUTION!
Do not use chemical flushes in your air
conditioning system as the chemicals can
damage your air conditioning components.
Such damage is not covered by the New
Vehicle Limited Warranty.

Air Conditioning Filter Replacement (A/C Air
Filter)
Refer to “Scheduled Servicing” in this sec-
tion for the proper maintenance intervals.
WARNING!
Do not remove the cabin air filter while the
vehicle is running, or while the ignition is
in the ACC or ON/RUN mode. With the
cabin air filter removed and the blower
operating, the blower can contact hands
and may propel dirt and debris into your
eyes, resulting in personal injury.
The A/C air filter is located in the fresh air
inlet behind the glove compartment. Perform
the following procedure to replace the filter:
1. Open the glove compartment and remove all contents. 2. There are glove compartment travel stops
on both sides of the glove compartment
door, partially close the glove compart-
ment door and push inward to release the
glove compartment travel stop on one side
and repeat this procedure for the opposite
side. 3. Pull the right hand side of the glove com-
partment door toward the rear of the ve-
hicle to disengage the glove compartment
door from its hinges.
NOTE:
When disengaging the glove compartment
door from its hinges, there will be some
resistance.
4. With the glove compartment door loose, remove the glove compartment tension
tether and tether clip by sliding the clip
toward the face of the glove compartment
door and lifting the clip out of glove com-
partment door.
5. Remove the filter cover by disengaging the retaining tab and mid way snap that
secures the filter cover to the HVAC hous-
ing. Disengage the mid way snap by pull-
ing the door outward. Unhinge the filter
cover on the right side to fully remove the
cover.
