NOTE:
• If fog or mist appears on the windshield orside glass, select Defrost mode and in-
crease 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 ra-
diator), for an accumulation of dirt or in-
sects. Clean with a gentle water spray from
the front of the radiator and through the
condenser.
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 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
Summer Operation
The engine cooling system must be protected
with a high-quality antifreeze coolant to pro-
vide proper corrosion protection and to pro-
tect against engine overheating. A solution of
50% OAT (Organic Additive Technology) cool-
ant that meets the requirements of FCA Ma-
terial Standard MS.90032 and 50% water is
recommended. Refer to “Dealer Service” in
“Servicing And Maintenance” 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 ad-
equate system lubrication 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 pro-
vide sufficient heating. If side window fog-
ging becomes a problem increase blower
speed. Vehicle windows tend to fog on the
inside in mild but rainy or humid weather.

bing retracts, you will hear a clicking
sound. This means the seat belt is now in
the Automatic Locking mode.
6. Try to pull the webbing out of the retractor. If it is locked, you should not be able to
pull out any webbing. If the retractor is not
locked, repeat step 5.
7. Finally, pull up on any excess webbing to tighten the lap portion around the child
restraint while you push the child restraint
rearward and downward into the vehicle
seat.
8. Test that the child restraint is installed tightly by pulling back and forth on the
child seat at the belt path. It should not
move more than 1 inch (25.4 mm) in any
direction.
Any seat belt system will loosen with time, so
check the belt occasionally, and pull it tight if
necessary.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 colli-
sion.
Pets should be restrained in the rear seat in
pet harnesses or pet carriers that are secured
by seat belts.
SAFETY TIPS
Transporting Passengers
NEVER TRANSPORT PASSENGERS IN THE
CARGO AREA.
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.
WARNING!
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.
Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They con-
tain carbon monoxide (CO), which is col-
orless and odorless. Breathing it can make
you unconscious and can eventually poi-
son you. To avoid breathing (CO), follow
these safety tips:
• Do not run the engine in a closed garageor in confined areas any longer than
needed to move your vehicle in or out of
the area.
69

WARNING!
• If you are required to drive with thetrunk/liftgate/rear doors open, make sure
that all windows are closed and the cli-
mate 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 out-
side air into the vehicle. Set the blower
at high speed.
The 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 com-
plete exhaust system and adjacent body ar-
eas 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 immedi-
ately. Do not disassemble or modify the sys-
tem.
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 web-
bing, etc.). If there is any question regarding
seat belt or retractor condition, replace the
seat belt.
Air Bag Warning Light
The Air Bag warning lightwill 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 your 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
cleared. If the light comes on intermittently
or remains on while driving, have your autho-
rized dealer service the vehicle immediately.
Refer to “Occupant Restraint Systems” in
“Safety” for further information.
