late the temperature, air flow, and direction of
air circulating throughout the vehicle. The
controls are located on the touchscreen (if
equipped) and on the instrument panel below
the radio.
Manual Climate Control Overview
The Manual Temperature Controls consist of a
series of three outer rotary dials (blower speed,
temperature and mode) and three inner push
buttons (Recirculation, A/C, Rear Window
Defroster).
Manual Temperature Controls
WARNING!
Sudden loss of visibility through the
windshield could lead to a collision. You might
not see other vehicles or other obstacles. To
avoid sudden icing of the windshield during
freezing weather, warm the windshield with
the defroster before and during windshield

Climate Control Functions
A/C (Air Conditioning)
The Air Conditioning (A/C) button allows the
operator to manually activate or deactivate the
air conditioning system. When the air condi -
tioning 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 manu -
ally adjust the blower and airflow mode settings.
Also, make sure to select only Panel, Bi-Level or
Floor modes.
NOTE:
For Manual Climate Controls, 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 if needed.
If your air conditioning performance seems
lower than expected, check the front of the
A/C condenser (located in front of the radi -
ator), for an accumulation of dirt or insects.
Clean with a gentle water spray from the front
of the radiator and through the condenser.
Recirculation
In cold weather, use of Recirculation mode may
lead to excessive window fogging. The Recircu -
lation feature may be unavailable if conditions
exist that could create fogging on the inside of
the windshield. On systems with Manual
Climate Controls, the Recirculation mode is not
allowed in Defrost mode to improve window
clearing operation. Recirculation is disabled
automatically if this mode is selected.
Attempting to use Recirculation while in this
mode causes the LED in the control button to
blink and then turns 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) coolant that
meets the requirements of FCA Material Stan -dard MS.90032 and 50% water is recom
-
mended. Refer to “Fluids And Lubricants” in
“Technical Specifications” for proper coolant
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 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.
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 suffi -
cient heating. If side window fogging becomes a
problem increase blower speed. Vehicle
windows tend to fog on the inside in mild but
rainy or humid weather.

34GETTING TO KNOW YOUR VEHICLE
NOTE:
Recirculate without A/C should not be used 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.
A/C Air Filter
The climate control system filters outside air
containing dust, pollen and some odors. Strong
odors cannot be totally filtered out. Refer to
“Dealer Service” in “Servicing and Mainte -
nance” for filter replacement instructions.
Operating Tips Chart
CAUTION!
Failure to follow these cautions can cause
damage to the heating elements:
Use care when washing the inside of the
rear window. Do not use abrasive window
cleaners on the interior surface of the
window. Use a soft cloth and a mild
washing solution, wiping parallel to the
heating 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 window.
Keep all objects a safe distance from the
window.WEATHER CONTROL

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 this chapter for further
information.
Odometer/Trip Odometer Display Area
US 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 odom -
eter reading the same as it was before the
repair or service. If the technician 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 displayed indicating the gear selector
position. Telltales “1,2,3,4,5,6” indicate the
manual mode has been engaged and the
gear selected is displayed. Refer to “Auto -
matic Transmission” in “Starting And Oper -
ating” for further information on Electronic
Range Select (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 temperature. Any reading within
the normal range indicates that the
engine cooling system is operating satis-
factorily.
The pointer will likely indicate a higher
temperature 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, refer to “Cooling System” in
“Servicing And Maintenance” and follow the
warnings under the Cooling System Pressure
Cap paragraph.
CAUTION!
Driving with a hot engine cooling system
could damage 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.
