•Continuous use of the Recirculation mode may make the inside air stuffy and window fog-
ging 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 outside air position for
maximum defogging.

mild washing solution, wiping parallel to the heat-
ing elements. Labels can be peeled off after soaking
with warm water.
• Do not use scrapers, sharp instruments, or abrasive
window cleaners on the interior surface of the win-

Climate Control Functions
A/C (Air Conditioning)
The Air Conditioning (A/C) button allows the operator to
manually activate or deactivate the air conditioning sys-
tem. When the air conditioning system is turned on, cool
dehumidified 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 increase 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. MAX A/C
MAX A/C sets the control for maximum cooling perfor-
mance.
Press and release to toggle between MAX A/C and the prior
settings. The button illuminates when MAX A/C is on.
In MAX A/C, the blower level and mode position can be
adjusted to desired user settings. Pressing other settings
will cause the MAX A/C operation to switch to the selected
setting and MAX A/C to exit.
Recirculation
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.
The Recirculation indicator will illuminate when this but-
ton is selected. Press the button a second time to turn off
the Recirculation mode and allow outside air into the
vehicle.
NOTE:
In cold weather, use of Recirculation mode may
lead to excessive window fogging. The Recirculation fea-
ture may be unavailable (button on the touchscreen greyed
out) if conditions exist that could create fogging on the
inside of the windshield.

Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corrosion
protection and to protect against engine overheating. OAT
coolant (conforming to MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is functioning
properly and the proper amount, type, and concentration
of coolant is used. Use of the Air Recirculation mode
during Winter months is not recommended, 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 adequate system
lubrication to minimize the possibility of compressor dam-
age 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 De-
frost 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 an authorized dealer to service your cabin
air filter, and to have it replaced when needed.

WINDOWS
Power Windows — If Equipped
The power window controls located on the driver’s door
trim panel have up-down switches that give you fingertip
control of all power windows. There is a single opening
and closing switch on the front passenger door for passen-
ger window control and on the rear doors of the Quad Cab
and Crew Cab models. The windows will operate when theignition switch is turned to the ON/RUN or ACC position,
and for up to 10 minutes after the ignition is turned OFF or
until a front door is opened.
NOTE:
The Key Off Power Delay feature will allow the
power windows to operate for up to 10 minutes after the
ignition is turned OFF. This feature is cancelled when
either front door is opened.
WARNING!
Never leave children unattended in a vehicle. Do not
leave the key fob in or near the vehicle or in a location
accessible to children, and do not leave the ignition of
a vehicle equipped with Keyless Enter-N-Go in the
ACC or ON/RUN mode. Occupants, particularly unat-
tended children, can become entrapped by the win-
dows while operating the power window switches.
Such entrapment may result in serious injury or death.
Auto-Down
Both the driver and front passenger window switch have
an Auto-Down feature. Push the window switch past the

first detent, release, and the window will go down auto-
matically. To cancel the Auto-Down movement, operate the
switch in either the up or down direction and release the
switch.
To stop the window from going all the way down during
the Auto-Down operation, pull up on the switch briefly.
To open the window part way, push to the switch to the
first detent and release it when you want the window to
stop.
Auto-Up Feature With Anti-Pinch Protection (4-Door
Models Driver And Front Passenger Door Only) —
If Equipped
Pull the window switch fully upward to the second detent,
release, and the window will go up automatically.
To stop the window from going all the way up during the
Auto-Up operation, push down on the switch briefly.
To close the window part way, lift the window switch to
the first detent and release when you want the window to
stop.NOTE:
If the window runs into any obstacle during the
Auto-Closure, it will reverse direction and then go back
down. Remove the obstacle and use the window switch
again to close the window. Any impact due to rough road
conditions may trigger the auto reverse function unexpect-
edly during auto closure. If this happens, pull the switch
lightly to the first detent and hold to close the window
manually.
WARNING!
There is no anti-pinch protection when the window is
almost closed. Be sure to clear all objects from the
window before closing.
Reset Auto-Up
Should the Auto-Up feature stop working, the window
may need to be reset. To reset Auto-Up:
1. Make sure the door is fully closed.
2. Pull the window switch up to close the window com- pletely and continue to hold the switch up for an
additional two seconds after the window is closed.

hold the switch down for an additional two seconds
after the window is fully open.
Window Lockout Switch (4–Door Models Only)
The window lockout switch on the driver’s door allows
you to disable the window control on the rear passenger
doors. To disable the window controls on the rear passen-
ger doors, push the window lock switch into the latched or
down position. To enable the window controls, push the
window lock switch again and return the switch to the
released or up position.
Wind Buffeting
Wind buffeting can be described as the perception of
pressure on the ears or a helicopter-type sound in the ears.
Your vehicle may exhibit wind buffeting with the windows
down, or the sunroof (if equipped) in certain open or
partially open positions. This is a normal occurrence and
can be minimized. If the buffeting occurs with the rear
windows open, open the front and rear windows together
to minimize the buffeting. If the buffeting occurs with the
sunroof open, adjust the sunroof opening to minimize the
buffeting or open any window.
