Press and release this button to change the system between recirculation mode and outside air
mode. Recirculation can be used when outside conditions such as smoke, odors, dust, or high
humidity are present.
NOTE:
•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.
•Recirculation can be used in all modes except for Defrost.
•The A/C can be deselected manually without disturbing the mode control selection.
Front Defrost Mode
Turn the Knob to the Front Defrost position. Air comes from the windshield and side window
demist outlets. When the defrost button is selected, the blower level will increase. Use Defrost

Additional Rear Climate Control — If Equipped
This switch, mounted on the instrument panel to the left of
the steering column, activates the additional rear heating/
air conditioning system vent.
NOTE:The switch must be enabled for operation by the
Upfitter.
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.
Recirculation

interior air by pressing the Recirculation control button.
The recirculation indicator will illuminate when this button
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. On systems with Manual
Climate Controls, the Recirculation mode is not allowed in
Defrost mode to improve window clearing operation.
Recirculation will be disabled automatically if this mode is
selected. Attempting to use Recirculation while in this
mode will cause the LED in the control button to blink and
then turn off.
Operating Tips
NOTE: Refer to the chart at the end of this section for
suggested control settings for various weather conditions.
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. A
solution of 50% OAT (Organic Additive Technology) cool-
ant that meets the requirements of FCA Material Standard MS.90032 and 50% water is recommended. Refer to “Dealer
Service” in “Servicing And Maintenance” for proper cool-
ant selection.
Winter Operation
Use of the air Recirculation mode during winter months is
not recommended because it may cause window fogging.
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 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 compressor dam-
age when the system is started again.
Window Fogging
Interior fogging on the windshield can be quickly removed
by turning the mode selector to Defrost. The Defrost/Floor
mode can be used to maintain a clear windshield and
provide sufficient heating. If side window fogging be-
comes a problem increase blower speed. Vehicle windows
tend to fog on the inside in mild but rainy or humid
weather.

Instrument Cluster Descriptions
1. Speedometer•Indicates vehicle speed.
2. Instrument Cluster Display •When the appropriate conditions exist, this display
shows instrument cluster display messages. Refer to
“Instrument Cluster Display” in “Getting To Know
Your Instrument Panel” for further information.
• Odometer/Trip Odometer Display Area
U.S. Federal regulations require that upon transfer of
vehicle ownership, the seller certify to the purchaser
the correct mileage that the vehicle has been driven. If
your odometer needs to be repaired or serviced, the
repair technician should leave the odometer reading
the same as it was before the repair or service. If s/he
cannot do so, then the odometer must be set at zero,
and a sticker must be placed in the door jamb stating
what the mileage was before the repair or service. It is
a good idea for you to make a record of the odometer
reading before the repair/service, so that you can be
sure that it is properly reset, or that the door jamb
sticker is accurate if the odometer must be reset at zero. •
Gear Selector Status (PRND)
The gear selector status “P,R,N,D,1,2,3,4,5,6” are dis-
played indicating the gear selector position. Telltales
“1,2,3,4,5,6” indicate the manual mode has been en-
gaged and the gear selected is displayed. Refer to
“Automatic Transmission” in “Starting And Operat-
ing” for further information on ERS.
3. Tachometer •This gauge measures engine revolutions per minute
(RPM x 1000). Before the pointer reaches the red area,
ease up on the accelerator to prevent engine damage.
4. Temperature Gauge •The temperature gauge shows engine coolant tem-
perature. Any reading within the normal range indi-
cates that the engine cooling system is operating
satisfactorily.
• The gauge pointer will likely indicate a higher tem-
perature when driving in hot weather or up mountain
grades. It should not be allowed to exceed the upper
limits of the normal operating range.

WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer for
service if your vehicle overheats. If you decide to look
under the hood yourself, see “Servicing And Mainte-
nance.” Follow the warnings under the Cooling System
Pressure Cap paragraph.
CAUTION!
Driving with a hot engine cooling system could dam-
age your vehicle. If the temperature gauge reads “H,”
pull over and stop the vehicle. Idle the vehicle with the
air conditioner turned off until the pointer drops back
into the normal range. If the pointer remains on the
“H,” turn the engine off immediately and call an
authorized dealer for service.5. Fuel Gauge
•The pointer shows the level of fuel in the fuel tank
when the ignition switch is in the ON/RUN position.
•
The fuel pump symbol points to the side of the
vehicle where the fuel door is located.
INSTRUMENT CLUSTER DISPLAY
Your vehicle may be equipped with an instrument cluster
display, which offers useful information to the driver. With
the ignition in the STOP/OFF mode, opening/closing of a
door will activate the display for viewing, and display the
total miles, or kilometers, in the odometer. Your instrument
cluster display is designed to display important informa-
tion about your vehicle’s systems and features. Using a
driver interactive display located on the instrument panel,
your instrument cluster display can show you how sys-
tems are working and give you warnings when they are
not. The steering wheel mounted controls allow you to
scroll through the main menus and submenus. You can
access the specific information you want and make selec-
tions and adjustments.

— Engine Temperature Warning Light
This light warns of an overheated engine condition. If the
engine coolant temperature is too high, this indicator will
illuminate and a single chime will sound.
If the light turns on while driving, safely pull over and stop
the vehicle. If the A/C system is on, turn it off. Also, shift
the transmission into NEUTRAL and idle the vehicle. If the
temperature reading does not return to normal, turn the
engine off immediately and call for service. Refer to “If
Your Engine Overheats” in “In Case Of Emergency” for
further information.
— Brake Warning Light
This light monitors various brake functions, including
brake fluid level and parking brake application. If the
brake light turns on it may indicate that the parking brake
is applied, that the brake fluid level is low, or that there is
a problem with the anti-lock brake system reservoir.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS) / Electronic Stability Control (ESC) system.In this case, the light will remain on until the condition has
been corrected. If the problem is related to the brake
booster, the ABS pump will run when applying the brake,
and a brake pedal pulsation may be felt during each stop.
The dual brake system provides a reserve braking capacity
in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.
NOTE:
The light may flash momentarily during sharp
cornering maneuvers, which change fluid level conditions.
The vehicle should have service performed, and the brake
fluid level checked.
If brake failure is indicated, immediate repair is necessary.
WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed. It
will take longer to stop the vehicle. You could have a
collision. Have the vehicle checked immediately.
76 GETTING TO KNOW YOUR INSTRUMENT PANEL

Vehicles equipped with the Anti-Lock Brake System (ABS)
are also equipped with Electronic Brake Force Distribution
(EBD). In the event of an EBD failure, the Brake Warning
Light will turn on along with the ABS Light. Immediate
repair to the ABS system is required.
Operation of the Brake Warning Light can be checked by
turning the ignition switch from the OFF position to the
ON/RUN position. The light should illuminate for ap-
proximately two seconds. The light should then turn off
unless the parking brake is applied or a brake fault is
detected. If the light does not illuminate, have the light
inspected by your authorized dealer.
The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN position.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake application.
— Oil Pressure Warning Light
This light indicates low engine oil pressure. If the light
turns on while driving, stop the vehicle and shut off the
engine as soon as possible. A chime will sound when this
light turns on. Do not operate the vehicle until the cause is corrected. This
light does not indicate how much oil is in the engine. The
engine oil level must be checked under the hood.
Yellow Warning Lights
— Vehicle Security Warning Light
This telltale will illuminate when the vehicle security alarm
system has detected an attempt was made to break into the
vehicle.
— Tire Pressure Monitoring System (TPMS)
Warning Light
The warning light switches on and a message is displayed
to indicate that the tire pressure is lower than the recom-
mended value and/or that slow pressure loss is occurring.
In these cases, optimal tire duration and fuel consumption
may not be guaranteed.
Should one or more tires be in the condition mentioned
above, the display will show the indications corresponding
to each tire in sequence.
