2013 JEEP GRAND CHEROKEE engine

Automatic Operation
1. Press the AUTO button on the Automatic
Temperature Control (ATC) Panel.
2. Next, adjust the temperature you would like
the system to maintain by adjusting the driver
and front passenger temperature control but-
tons. Once the desired temperature is dis-
played, the system will achieve and automati-
cally maintain that comfort level.
3. When the system is set up for your comfort
level, it is not necessary to change the settings.
You will experience the greatest efficiency by
simply allowing the system to function automati-
cally.
NOTE:
•It is not necessary to move the tempera-
ture settings for cold or hot vehicles. The
system automatically adjusts the tem-
perature, mode and fan speed to provide
comfort as quickly as possible. •
The temperature can be displayed in U.S.
or Metric units by selecting the US/M
customer-programmable feature. Refer to
the “Electronic Vehicle Information Cen-
ter (EVIC) — Customer-Programmable
Features (SETUP)” in this section of the
manual.
To provide you with maximum comfort in the
Automatic mode, during cold start-ups, the
blower fan will remain on low until the engine
warms up. The blower will increase in speed
and transition into Auto mode.
Manual Operation
This system offers a full complement of manual
override features.
NOTE:
Each of these features operate indepen-
dently from each other. If any one feature is
controlled manually, temperature control
will continue to operate automatically. Blower Control
There are seven fixed
blower speeds. Use the
outer dial control to regu-
late the amount of air
forced through the sys-
tem in any mode you se-
lect. The blower speed
increases as you move
the control clockwise and
decreases when you move the control counter-
clockwise.
The blower fan speed can be set to any fixed
speed by adjusting the blower control outer dial.
The fan will now operate at a fixed speed until
additional speeds are selected. This allows the
front occupants to control the volume of air
circulated in the vehicle and cancel the Auto
mode.
The operator can also select the direction of the
airflow by selecting one of the following
positions.

Recirculation ControlWhen outside air contains smoke,
odors, or high humidity, or if rapid
cooling is desired, you may wish to
recirculate interior air by pressing
the Recirculation control button.
Recirculation mode should only be
used temporarily. The recirculation LED will
illuminate when this button is selected. Push the
button a second time to turn off the Recircula-
tion mode LED and allow outside air into the
vehicle.
NOTE:
In cold weather, use of Recirculation mode
may lead to excessive window fogging. The
Recirculation mode is not allowed in the
Defrost mode to improve window clearing
operation. Recirculation will be disabled au-
tomatically if this mode is selected.Operating Tips
Window Fogging
Windows will fog on the inside when the humid-
ity inside the vehicle is high. This often occurs in
mild or cool temperatures when it’s rainy or
humid. In most cases, turning the air condition-
ing (pressing the A/C button) on will clear the
fog. Adjust the temperature control, air direc-
tion, 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 se-
lecting 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
NOTE:
In some cases during high temperature
trailer tow operation the Air Conditioning
system performance may be reduced. This
is to help protect the engine from overheat-
ing during the high load condition.
Your air conditioning system is also equipped
with an automatic recirculation system. When
the system senses a heavy load or high heat
conditions, it may use partial Recirculation A/C
mode to provide additional comfort.
Winter Operation
When operating the system during the winter
months, make sure the air intake, located di-
rectly in front of the windshield, is free of ice,
slush, snow, or other obstructions.
Vacation/Storage
Any time 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
in high. This will ensure adequate system lubri-
cation to minimize the possibility of compressor
damage when the system is started again.
