GETTING TO KNOW YOUR VEHICLE33
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.

42GETTING TO KNOW YOUR INSTRUMENT PANEL
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.

SAFETY89
(Continued)
(Continued)
Transporting Pets
Air Bags deploying in the front seat could harm
your pet. An unrestrained pet will be thrown
about and possibly injured, or injure a
passenger during panic braking or in a collision.
Pets should be restrained in the rear seat (if
equipped) in pet harnesses or pet carriers that
are secured by seat belts.
SAFETY TIPS
Transporting Passengers
NEVER TRANSPORT PASSENGERS IN THE
CARGO AREA.
Exhaust Gas The best protection against carbon monoxide
entry into the vehicle body is a properly main
-
tained 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 is damaged,
have a competent mechanic inspect the
complete 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 addi -
tion, inspect the exhaust system each time the
vehicle is raised for lubrication or oil change.
Replace as required.
WARNING!
Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury or
death.
It is extremely dangerous to ride in a cargo
area, inside or outside of a vehicle. In a
collision, people riding in these areas are
more likely to be seriously injured or killed.
Do not allow people to ride in any area of
your vehicle that is not equipped with seats
and seat belts.
Be sure everyone in your vehicle is in a seat
and using a seat belt properly.
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you
unconscious and can eventually poison you.
To avoid breathing (CO), follow these safety
tips:
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 you are required to drive with the trunk/
liftgate/rear doors 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.
WARNING!
(Continued)

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.

STARTING AND OPERATING119
Automatic Transmission
The DRIVE range can be selected when towing.
The transmission controls include a drive
strategy to avoid frequent shifting when towing.
However, if frequent shifting does occur while in
DRIVE, select TOW/HAUL mode or select a lower
gear range (using the Electronic Range Select
(ERS) shift control).
NOTE:
Using TOW/HAUL mode or selecting a lower
gear range (using the ERS shift control) while
operating the vehicle under heavy loading
conditions will improve performance and
extend transmission life by reducing excessive
shifting and heat build up. This action will also
provide better engine braking.
When towing a loaded trailer up steep grades at
low speeds, holding your vehicle in first gear
(using the ERS shift control) can help to avoid
transmission overheating.
Tow/Haul Mode
To reduce potential for automatic transmission
overheating, activate TOW/HAUL mode when
driving in hilly areas, or select a lower gear
range (using the Electronic Range Select (ERS)
shift control) on more severe grades.
Speed Control — If Equipped
Do not use on hilly terrain or with heavy
loads.
When using the speed control, if you experi -
ence speed drops greater than 10 mph
(16 km/h), disengage until you can get back
to cruising speed.
Use speed control in flat terrain and with light
loads to maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission
overheating, take the following actions:
City Driving
In city traffic — while stopped, place the trans -
mission in NEUTRAL, but do not increase engine
idle speed.
Highway Driving
Reduce speed.
Temporarily turn off air conditioning.

IN CASE OF EMERGENCY145
JUMP STARTING
If your vehicle has a discharged battery, it can
be jump started using a set of jumper cables
and a battery in another vehicle or by using a
portable battery booster pack. Jump starting
can be dangerous if done improperly, so please
follow the procedures in this section carefully.
NOTE:
When using a portable battery booster pack,
follow the manufacturer’s operating instruc -
tions and precautions.
Preparations For Jump Start
The vehicle’s jump starting remote posts are
located under the hood, in the engine compart -
ment on the driver's side.
The Remote Positive (+) Post is covered with a
protective cap located on the side of the Front
Power Distribution Center.
The Remote Negative (-) Post is located on the
core support closest to the front of the vehicle.
Jump Starting Locations 1. Apply the parking brake, shift the automatic
transmission into PARK (P) and turn the
ignition to the OFF position.
2. Turn off the heater, radio, and all unneces -
sary electrical accessories.
3. If using another vehicle to jump start the battery, park the vehicle within the jumper
cables reach, apply the parking brake and
make sure the ignition is OFF.
WARNING!
Do not attempt jump starting if the battery is
frozen. It could rupture or explode and cause
personal injury.
CAUTION!
Do not use a portable battery booster pack or
any other booster source with a system
voltage greater than 12 Volts or damage to
the battery, starter motor, alternator or
electrical system may occur.(+) — Remote Positive Post
(-) — Remote Negative Post
WARNING!
Take care to avoid the radiator cooling fan
whenever the hood is raised. It can start
anytime the ignition switch is ON. You can
be injured by moving fan blades.
Remove any metal jewelry such as rings,
watch bands and bracelets that could
make an inadvertent electrical contact. You
could be seriously injured.
Batteries contain sulfuric acid that can
burn your skin or eyes and generate
hydrogen gas which is flammable and
explosive. Keep open flames or sparks
away from the battery.

IN CASE OF EMERGENCY147
3. Disconnect the positive end (+) of the
jumper cable from the positive (+) post of
the booster battery.
4. Disconnect the opposite end of the positive (+) jumper cable from the remote positive
(+) post of the discharged vehicle.
5. Close the cover of the Front Power Distribu -
tion Center.
If frequent jump starting is required to start your
vehicle you should have the battery and
charging system inspected at an authorized
dealer.Battery Location
There are two remote jump starting posts under
the hood which is the recommended jump start
location. If access to the battery is needed, an
access panel on the driver’s side floor will allow
for battery access.

Battery Location
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can
reduce the potential for overheating by taking
the appropriate action.
On the highways — slow down.
In city traffic — while stopped, place the trans -
mission in NEUTRAL (N), but do not increase
the engine idle speed while preventing
vehicle motion with the brakes.
NOTE:
There are steps that you can take to slow down
an impending overheat condition:
If your Air Conditioner (A/C) is on, turn it off.
The A/C system adds heat to the engine
cooling system and turning the A/C off can
help remove this heat.
You can also turn the temperature control to
maximum heat, the mode control to floor and
the blower control to high. This allows the
heater core to act as a supplement to the
radiator and aids in removing heat from the
engine cooling system.
CAUTION!
Accessories plugged into the vehicle power
outlets draw power from the vehicle’s battery,
even when not in use (i.e., cellular devices,
etc.). Eventually, if plugged in long enough
without engine operation, the vehicle’s
battery will discharge sufficiently to degrade
battery life and/or prevent the engine from
starting.
