speed and transition into Auto mode.
Manual Operation Override
This system offers a full complement of
manual override features. The AUTO symbol
in the front ATC display will be turned off
when the system is being used in the manual
mode.
Operating Tips
NOTE:
For suggested control settings for various
weather conditions, refer to “Climate
Controls” in “Getting To Know Your Vehicle”
in the Owner’s Manual.
Summer Operation
The engine cooling system must be
protected with a high-quality antifreeze
coolant to provide proper corrosion protec -
tion and to protect against engine over -
heating. OAT coolant (conforming to
MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and
defroster performance, make sure the engine
cooling system is functioning properly and
the proper amount, type, and concentration
of coolant is used. Use of the Air Recircula -
tion 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 damage 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 Defrost 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.
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 inte-
rior surface of the window.
Keep all objects a safe distance from the
window.

Outside Air Intake
Make sure the air intake, located directly in
front of the windshield, is free of obstruc-
tions, 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 autho -
rized dealer to service your cabin air filter,
and to have it replaced when needed.
Stop/Start System — If Equipped
While in an Autostop, the Climate Control
system may automatically adjust airflow to
maintain cabin comfort. Customer settings
will be maintained upon return to an engine
running condition.
Windshield Wiper De-icer — If Equipped
The windshield wiper de-icer is a heating
element located at the base of the wind -
shield.
It operates automatically once the following
conditions are met:
Activation By Front Defrost
The wiper de-icer activates automatically
during a cold weather manual start with
full defrost, and when the ambient tem-
perature is below 33°F (0.6°C) .
Activation By Rear Defrost
The wiper de-icer activates automatically
when the Rear Defrost is operating and
the ambient temperature is below 33°F
(0.6°C) .
Activation By Remote Start Operation
When the Remote Start is activated and
the outside ambient temperature is less
than 33°F (0.6°C) the windshield wiper
de-icer is activated. Upon exiting Remote
Start, the climate control functions will
resume their previous operation except, if
the de-icer is active, the de-icer timer
and operation will continue.

Exhaust GasThe best protection against carbon monoxide
entry into the vehicle body is a properly
maintained 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
addition, inspect the exhaust system each
time the vehicle is raised for lubrication or oil
change. Replace as required.
Safety Checks You Should Make Inside
The Vehicle
Seat Belts

Inspect the seat belt system periodically,
checking for cuts, frays, and loose parts.
Damaged parts must be replaced immediately.
Do not disassemble or modify the system.
Front seat belt assemblies must be replaced
after a collision. Rear seat belt assemblies
must be replaced after a collision if they
have been damaged (i.e., bent retractor, torn
webbing, etc.). If there is any question
regarding seat belt or retractor condition,
replace the seat belt.
Air Bag Warning Light
The Air Bag warning light will turn on for
four to eight seconds as a bulb check when
the ignition switch is first turned to ON/RUN.
If the light is either not on during starting,
stays on, or turns on while driving, have the
system inspected at an authorized dealer as
soon as possible. After the bulb check, this
light will illuminate with a single chime when
a fault with the Air Bag System has been
detected. It will stay on until the fault is
removed. If the light comes on intermittently
or remains on while driving, have an autho
-
rized dealer service the vehicle immediately.
Refer to “Occupant Restraint Systems” in
“Safety” for further information.
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 recircula-
tion mode.
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.

Normal Starting — Diesel Engine
Before starting your vehicle, adjust your seat,
both inside and outside mirrors, and fasten
your seat belts.
The starter is allowed to crank for up to
30-second intervals. Waiting a few minutes
between such intervals will protect the
starter from overheating.NOTE:
Engine start up in very low ambient tempera-
ture could result in evident white smoke.
This condition will disappear as the engine
warms up.
Battery Blanket Usage
A battery loses 60% of its cranking power as
the battery temperature decreases to 0°F
(-18°C). For the same decrease in tempera -
ture, the engine requires twice as much
power to crank at the same RPM. The use of
battery blankets will greatly increase starting
capability at low temperatures. Suitable
battery blankets are available from your
authorized Mopar dealer.
Normal Starting Procedure — Keyless
Enter-N-Go
Observe the instrument panel telltales when
starting the engine.
NOTE:
Normal starting of either a cold or a warm
engine is obtained without pumping or
pressing the accelerator pedal.
1. Always apply the parking brake.
2. Press and hold the brake pedal while pushing the ENGINE START/STOP
button once.
NOTE:
A delay of the start of up to five seconds is
possible under very cold conditions. The
“Wait to Start” telltale will be illuminated
WARNING!
Before exiting a vehicle, always come to
a complete stop, then shift the auto-
matic transmission into PARK and apply
the parking brake.
Always make sure the keyless ignition
node is in the OFF mode, key fob is
removed from the vehicle and vehicle is
locked.
Never leave children alone in a vehicle,
or with access to an unlocked vehicle.
Leaving children 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 gear selector.
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. A child could operate power
windows, other controls, or move the
vehicle.
Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury or
death.
CAUTION!
The engine is allowed to crank as long as
30 seconds. If the engine fails to start
during this period, please wait at least two
minutes for the starter to cool before
repeating start procedure.
