2010 JEEP GRAND CHEROKEE climate control

Do not run the engine in a closed garage or in confined
areas any longer than needed to move your vehicle in or
out of the area.
If it is necessary to sit in a parked vehicle with the engine
running, adjust your heating or cooling controls to force
outside air into the vehicle. Set the blower at high speed.
If you are required to drive with the trunk/liftgate open,
make sure that all windows are closed and the climate
control BLOWER switch is set at high speed. DO NOT
use the recirculation mode.
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle isdamaged, have a competent mechanic inspect the com-
plete exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open
seams or loose connections could permit exhaust fumes
to seep into the passenger compartment. In addition,
inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required.
Safety Checks You Should Make Inside the
Vehicle
Seat Belts
Inspect the belt system periodically, checking for cuts,
frays, and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Front seat belt assemblies must be replaced after a
collision. Rear seat belt assemblies must be replaced after
a collision if they have been damaged (i.e., bent retractor,
torn webbing, etc.). If there is any question regarding belt
or retractor condition, replace the belt.
72 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Rotate the switch upward to the “On” position to
activate the rear wiper.
NOTE: The rear wiper operates in an intermittent mode
only.
Rotate the switch upward to the “washer” position
to activate that rear washer. The washer pump will
continue to operate as long as the lever or ring is
engaged. Upon release, the wipers will cycle two times
before returning to the set position.
If the rear wiper is operating when the ignition is turned
OFF, the wiper will automatically return to the “park”
position if power accessory delay is active. Power acces-
sory delay can be cancelled by opening the door; if this
happens, the rear wiper will stop at its current position
and will not go to “park”. If the liftgate flipper glass is open, connection to the rear
window wiper is interrupted preventing activation of the
rear wiper blade. When the liftgate flipper glass is closed,
the rear wiper switch, or the ignition switch, needs to be
turned OFF and ON to restart the rear wiper.
Rear Window Defroster
The rear window defroster button is located on the
climate control panel. Press this button to turn on
the rear window defroster and the heated outside mirrors
(if equipped). An indicator in the button will illuminate
when the rear window defroster is on. The rear window
defroster automatically turns off after approximately
10 minutes. For an additional five minutes of operation,
press the button a second time.
NOTE: To prevent excessive battery drain, use the rear
window defroster only when the engine is operating.

lar disc, it may be damaged (i.e., scratched, reflective
coating removed, a hair, moisture or dew on the disc)
oversized, or have protection encoding. Try a known
good disc before considering disc player service.
RADIO OPERATION AND CELLULAR PHONES
Under certain conditions, the cellular phone being on in
your vehicle can cause erratic or noisy performance from
your radio. This condition may be lessened or eliminated
by relocating the cellular phone antenna. This condition
is not harmful to the radio. If your radio performance
does not satisfactorily “clear” by the repositioning of the
antenna, it is recommended that the radio volume be
turned down or off during cellular phone operation.

The system will automatically control re-
circulation. However, pressing this but-
ton will temporarily put the system in
“Recirculation” mode. This can be used
when outside conditions such as smoke,
odors, dust, or high humidity are present. This will cause
the LED to illuminate.
NOTE:
•The surface of the climate control panel, and the top
center of the instrument panel should be kept free of
debris due to the climate control sensor’s location.
Mud on the windshield may also cause poor operation
of this system.
•To provide you with maximum comfort in the auto-
matic mode, during cold start-ups the blower fan will
remain off until the engine warms up. However, the
fan will engage immediately if the defrost mode is
selected or if you manually select a blower speed.
•Under certain conditions (after the vehicle is turned
off) the climate control system may recalibrate and a
noise may be heard for 20 seconds. This is part of
normal operation.
•Most of the time, when in Automatic operation, you
can temporarily put the system into Recirculation
mode by pressing the “Recirculation” button. How-
ever, under certain conditions in automatic the system
is blowing air out of the defrost vents. When these
conditions are present, and the “Recirculation” button
is pressed, the indicator will flash and remain off. This
tells you that you are unable to go into Recirculation
mode at this time. If you would like to go to Recircu-
lation mode, you must first move your mode knob to
Panel, Panel/Floor, or Floor, then press the “Recircu-
lation” button. This feature will reduce the possibility
of window fogging.

HAZARD WARNING FLASHERS
The Hazard Warning flasher switch is located on the
switch bank just above the climate controls.Press the switch to turn on the Hazard Warning
flasher. When the switch is activated, all directional

Hazard Warning flasher will continue to operate with the
ignition key removed and the vehicle locked.
NOTE: With extended use, the Hazard Warning flasher
may run down your battery.
