Headliner ModeAir comes from the outlets in the headliner. Each
of these outlets can be individually adjusted to
direct the flow of air. Moving the air vanes of the outlets
to one side will shut off the airflow.
Bi-Level Mode
Air comes from both the headliner outlets and the
floor outlets.
NOTE: In many temperature positions, the Bi-Level
mode is designed to provide cooler air out of the head-
liner outlets and warmer air from the floor outlets.
Floor Mode
Air comes from the floor outlets.Operating Tips
NOTE: Refer to the chart at the end of this section for
suggested control settings for various weather condi-
tions.
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corro-
sion protection and to protect against engine overheating.
OAT coolant (conforming to MS.90032) is recommended.
Refer to “Fluids Aand Lubricants” in “Technical Data”
for proper coolant selection.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is function-
ing properly and the proper amount, type, and concen-
tration of coolant is used. Refer to “Fluids Aand

shows the 3.5” EVIC OR 7” DID messages. Refer to
“Display” located in “Getting To Know Your Instru-
ment Panel” for further information.
3. Speedometer •Indicates vehicle speed.
4. Fuel Gauge •The gauge 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.
5. 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 can 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!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge
reaches “H” pull over and stop the vehicle. Idle the
vehicle with the air conditioner turned off until the

Coolant Temperature Warning Light
Red TelltaleLight What It Means
Coolant Temperature Warning Light
This light warns of an overheated engine condition. 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.
NOTE:
As the coolant temperature gauge approaches
H,this indicator will illuminate and a single
chime will sound. Further overheating will cause the temperature gauge to reach H.In this
case, a continuous chime will sound until the engine is allowed to cool or the 4 minutes du-
ration is expired, whichever come first.

•Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough
idle or malfunctioning operating conditions.
Cooling System
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If
you see or hear steam coming from under the hood,
do not open the hood until the radiator has had time
to cool. Never try to open a cooling system pressure
cap when the radiator or coolant bottle is hot.
Engine Coolant Checks
Check the engine coolant (antifreeze) protection every 12
months (before the onset of freezing weather, where
applicable). If the engine coolant (antifreeze) is dirty, the system should be drained, flushed, and refilled with
fresh OAT coolant (conforming to MS.90032) by an
authorized dealer. Check the front of the A/C condenser
for any accumulation of bugs, leaves, etc. If dirty, clean by
gently spraying water from a garden hose vertically
down the face of the condenser.
Check the engine cooling system hoses for brittle rubber,
cracking, tears, cuts, and tightness of the connection at
the coolant recovery bottle and radiator. Inspect the
entire system for leaks.
With the engine at normal operating temperature (but
not running), check the cooling system pressure cap for
proper vacuum sealing by draining a small amount of
engine coolant (antifreeze) from the radiator drain cock.
If the cap is sealing properly, the engine coolant (anti-
freeze) will begin to drain from the coolant recovery
bottle. DO NOT REMOVE THE COOLANT PRESSURE
CAP WHEN THE COOLING SYSTEM IS HOT.

CAUTION!(Continued)
rust inhibitors or antirust products, as they may not
be compatible with the radiator engine coolant and
may plug the radiator.
• This vehicle has not been designed for use with
propylene glycol-based engine coolant (antifreeze).
Use of propylene glycol-based engine coolant (an-
tifreeze) is not recommended.
Adding Coolant
Your vehicle has been built with an improved engine
coolant (OAT coolant conforming to MS.90032) that al-
lows extended maintenance intervals. This engine cool-
ant (antifreeze) can be used up to ten years or 150,000
miles (240,000 km) before replacement. To prevent reduc-
ing this extended maintenance period, it is important that
you use the same engine coolant (OAT coolant conform-
ing to MS.90032) throughout the life of your vehicle. Please review these recommendations for using Organic
Additive Technology (OAT) engine coolant (antifreeze)
that meets the requirements of FCA Material Standard
MS.90032. When adding engine coolant (antifreeze):
•
We recommend using MOPAR Antifreeze/Coolant 10
Year/150,000 Mile Formula OAT (Organic Additive
Technology) that meets the requirements of FCA Ma-
terial Standard MS.90032.
• Mix a minimum solution of 50% OAT engine coolant
that meets the requirements of FCA Material Standard
MS.90032 and distilled water. Use higher concentra-
tions (not to exceed 70%) if temperatures below 34°F
(37°C) are anticipated.
• Use only high purity water such as distilled or deion-
ized water when mixing the water/engine coolant
(antifreeze) solution. The use of lower quality water
will reduce the amount of corrosion protection in the
engine cooling system.
632 MAINTAINING AND CARING FOR YOUR VEHICLE

Please note that it is the owner’s responsibility to main-
tain the proper level of protection against freezing ac-
cording to the temperatures occurring in the area where
the vehicle is operated.
NOTE:
•Some vehicles require special tools to add coolant
properly. Failure to fill these systems properly could
lead to severe internal engine damage. If any coolant is
needed to be added to the system, please contact your
local authorized dealer.
• Mixing engine coolant (antifreeze) types is not recom-
mended and can result in cooling system damage. If
HOAT and OAT coolant are mixed in an emergency,
have a authorized dealer drain, flush, and refill with
OAT coolant (conforming to MS.90032) as soon as
possible.Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of engine
coolant (antifreeze), and to ensure that engine coolant
(antifreeze) will return to the radiator from the coolant
recovery tank.
The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
WARNING!
• Do not open hot engine cooling system. Never add
engine coolant (antifreeze) when the engine is
overheated. Do not loosen or remove the cap to cool
an overheated engine. Heat causes pressure to
build up in the cooling system. To prevent scalding
or injury, do not remove the pressure cap while the
system is hot or under pressure.

WARNING!(Continued)
•Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or en-
gine damage may result.
Disposal Of Used Engine Coolant
Used ethylene glycol-based engine coolant (antifreeze) is
a regulated substance requiring proper disposal. Check
with your local authorities to determine the disposal
rules for your community. To prevent ingestion by ani-
mals or children, do not store ethylene glycol-based
engine coolant in open containers or allow it to remain in
puddles on the ground. If ingested by a child or pet, seek
emergency assistance immediately. Clean up any ground
spills immediately.
Coolant Level
The coolant expansion bottle provides a quick visual
method for determining that the coolant level is ad-
equate. With the engine off and cold, the level of the
engine coolant (antifreeze) in the bottle should be be-
tween the “MAX” and “MIN” lines marked on the bottle.
As long as the engine operating temperature is satisfac-
tory, the coolant bottle need only be checked once a
month.
When additional engine coolant (antifreeze) is needed to
maintain the proper level, it should be added to the
coolant bottle. Do not overfill.
