JEEP GRAND CHEROKEE 2010 Owner handbook (in English)

Mode Control (Air Direction)
Push the mode control buttons to choose from
several patterns of air distribution.
PanelAir is directed through the outlets in the
instrument panel. These outlets can be
adjusted to direct airflow.
NOTE:
The center instrument panel outlets can be
aimed so that they are directed toward the
rear seat passengers for maximum airflow
to the rear.
Bi-Level Air is directed through the panel and
floor outlets.
NOTE:
For all settings except full cold or full hot,
there is a difference in temperature between
the upper and lower outlets. The warmer air
flows to the floor outlets. This feature gives
improved comfort during sunny but cool
conditions. Floor
Air is directed through the floor outlets
with a small amount flowing through the
defrost and side window demist outlets.
Mix Air is directed through the floor, defrost,
and side window demist outlets. This
setting works best in cold or snowy
conditions that require extra heat to the
windshield. This setting is good for maintaining
comfort while reducing moisture on the wind-
shield.
Defrost Air is directed through the windshield
and side window demist outlets. Use
this mode with maximum blower and
temperature settings for best windshield and
side window defrosting.
NOTE:
• In Floor, Mix and Defrost modes a small
amount of air will flow through the out-
board panel outlets for occupant comfort.
• The air conditioning compressor oper-
ates in Mix, Defrost, or a blend of these
modes, even if the Air Conditioning (A/C) button is not pressed. This dehumidifies
the air to help dry the windshield. To
improve fuel economy, use these modes
only when necessary.
Recirculation Control Pressing the Recirculation Control
button will put the system in recir-
culation mode. This can be used
when outside conditions such as
smoke, odors, dust, or high humid-
ity are present. Activating recircu-
lation will cause the LED in the control button to
illuminate.
NOTE:
• Continuous use of the recirculation mode
may make the inside air stuffy and win-
dow fogging may occur. Extended use of
this mode is not recommended.
• The use of the recirculation mode in cold
or damp weather could cause windows to
fog on the inside, because of moisture
buildup inside the vehicle. Select the Out-
side Air position for maximum defogging.
• The A/C will engage automatically to pre-
vent fogging when the recirculation but-
187

ton is pressed and the mode control is set
to panel or panel / floor.
• The A/C can be deselected manually with-
out disturbing the mode control selection.
• When the ignition switch is turned to the
LOCK position or the ignition switch
START/STOP button is cycled to OFF, the
recirculation feature will be cancelled.
Air Conditioning Control Press this button to en-
gage the Air Condition-
ing. A light will illumi-
nate when the Air
Conditioning System is
engaged. Rotating the
dial left into the blue
area of the scale indi-
cates cooler tempera-
tures while rotating right
into the red area indicates warmer tempera-
tures.
NOTE:
The air conditioning compressor will not
engage until the engine has been running
for about 10 seconds. •
MAX A/C
For maximum cooling use the A/C and recircu-
lation buttons at the same time.

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 auto-
matically.
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.
There are seven fixed
blower speeds. Use
the outer dial control
to regulate the amount
of air forced through
the system in any
mode you select. The
blower speed in-
creases 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 al-
lows 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 posi-
tions.
Panel Mode
Air comes from the outlets in the instru-
ment panel. Each of these outlets can be
individually adjusted to direct the flow of
air. The air vanes of the center outlets and
outboard outlets can be moved up and down or
side to side to regulate airflow direction. There
is a shut off wheel located below the air vanes
to shut off or adjust the amount of airflow from
these outlets.
Bi-Level Mode Air comes from the instrument panel
outlets, floor outlets and defrost outlets.
190

NOTE:
In many temperature positions, the BI-
LEVEL mode is designed to provide cooler
air out of the panel outlets and warmer air
from the floor outlets.
Floor Mode
Air comes from the floor outlets. A slight
amount of air is directed through the
defrost and side window demister outlets.
Mix ModeAir comes from the floor, defrost and
side window demist outlets. This mode
works best in cold or snowy conditions.
It allows you to stay comfortable while
keeping the windshield clear.
Defrost Mode Air comes from the windshield and side
window demist outlets. Use Defrost
mode with maximum temperature set-
tings for best windshield and side window
defrosting. When the defrost mode is selected,
the blower will automatically default to medium-
high unless the blower is controlled manually. NOTE:
While operating in the other modes, the
system will not automatically sense the
presence of fog, mist or ice on the wind-
shield. Defrost mode must be manually se-
lected to clear the windshield and side
glass.
Air Conditioning (A/C)
The Air Conditioning (A/C) button allows the
operator to manually activate or deactivate the
air conditioning system. When in A/C mode and
the ATC is set to a cool temperature, dehumidi-
fied air flows through the air outlets. If Economy
mode is desired, press the A/C button to turn
off the A/C mode in the ATC display and
deactivate the A/C system.
NOTE:
•
If the system is in Mix, Floor or Defrost
Mode, the A/C can be turned off, but the
A/C system shall remain active to prevent
fogging of the windows.
• If fog or mist appears on the windshield or
side glass, select Defrost mode and in-
crease blower speed. Recirculation Control
When 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 but-
ton. 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
Recirculation 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
Floor/Defrost Mix and Defrost modes to im-
prove window clearing operation. Recircula-
tion will be disabled automatically if these
modes are 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
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
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
Anytime 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 the fresh air and high blower
setting. This will ensure adequate system lubri-
cation to minimize the possibility of compressor
damage when the system is started again.
