JEEP GRAND CHEROKEE 2013 WK2 / 4.G SRT Owners Manual

Floor ModeAir comes from the floor outlets. A slight amount
of air is directed through the defrost and side
window demister outlets.
Mix Mode
Air 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 settings 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 windshield. Defrost mode must be manually
selected 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, dehumidified 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. Also, make sure to select only
Panel, Bi-Level or Floor modes.

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 increase 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 button. Re-
circulation 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 Defrost modes to improve
window clearing operation. Recirculation will be dis-
abled automatically if Defrost is selected.
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 the air conditioning (pressing the A/C button) on
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
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
overheating 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 directly in front of the
windshield, is free of ice, slush, snow, or other obstruc-
tions.
Vacation Storage
Anytime you store your vehicle, or keep it out of service
(i.e. vacation) for two weeks or more, run the air condi-
tioning system at idle for about five minutes in the fresh
air and high blower setting. This will ensure adequate
system lubrication to minimize the possibility of com-
pressor damage when the system is started again.4

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust the
inside and outside mirrors, fasten your seat belt, and if
present, instruct all other occupants to buckle their seat
belts.
WARNING!
•When leaving the vehicle, always remove the key
fob from the ignition and lock your vehicle.
• Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured. Children should be
warned not to touch the parking brake, brake pedal
or the shift lever.
(Continued)
WARNING! (Continued)
•Do not leave the key fob in or near the vehicle (or
in a location accessible to children), and do not
leave a vehicle equipped with Keyless Enter-N-
Go™ in the ACC or ON/RUN mode. A child could
operate power windows, other controls, or move
the vehicle.
Automatic Transmission
The shift lever must be in the NEUTRAL or PARK
position before you can start the engine. Apply the brakes
before shifting into any driving gear.5
STARTING AND OPERATING 447

CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•Do not shift from REVERSE, PARK, or NEUTRAL
into any forward gear when the engine is above
idle speed.
• Shift into PARK only after the vehicle has come to
a complete stop.
• Shift into or out of REVERSE only after the vehicle
has come to a complete stop and the engine is at
idle speed.
• Before shifting into any gear, make sure your foot
is firmly on the brake pedal.
Using Fob With Integrated Key (Tip Start)
NOTE: Normal starting of either a cold or a warm
engine is obtained without pumping or pressing the
accelerator pedal. Do not
press the accelerator. Use the Fob with Integrated
Key to briefly turn the ignition switch to the START
position and release it as soon as the starter engages. The
starter motor will continue to run, and it will disengage
automatically when the engine is running. If the engine
fails to start, the starter will disengage automatically in 10
seconds. If this occurs, turn the ignition switch to the
LOCK position, wait 10 to 15 seconds, then repeat the
“Normal Starting” procedure.
Keyless Enter-N-Go™
This feature allows the driver to oper-
ate the ignition switch with the push
of a button, as long as the ENGINE
START/STOP button is installed and
the Remote Start/Keyless Enter-N-
Go™ FOBIK is in the passenger
compartment.
