Climate Control Functions
A/C (Air Conditioning)
The Air Conditioning (A/C) button allows the operator to
manually activate or deactivate the air conditioning sys-
tem. When the air conditioning system is turned on, cool
dehumidified air will flow through the outlets into the
cabin. For improved fuel economy, push the A/C button to
turn off the air conditioning and manually 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 radiator), 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 Recirculation feature may
be unavailable if conditions exist that could create fogging
on the inside of the windshield.
Automatic Temperature Control (ATC) — If
Equipped
Automatic Operation
1. Push the AUTO button on the faceplate.
2. Next, adjust the temperature you would like the system
to maintain by adjusting the temperature control but-
tons. Once the desired temperature is displayed, the
system achieves and automatically maintains that com-
fort level.
3. When the system is set up for your comfort level, it is not necessary to change the settings. You experience the
greatest efficiency by simply allowing the system to
function automatically.

•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.
1. Apply the parking brake, place the transmission into PARK and turn the ignition to LOCK.
2. Turn off the heater, radio, and all unnecessary electrical accessories.
3. Remove the protective cover over the positive (+)bat-
tery post.
4. 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 allow vehicles to touch each other as this could
establish a ground connection and personal injury
could result.
Jump Starting Procedure
WARNING!
Failure to follow this jump starting procedure could
result in personal injury or property damage due to
battery explosion.
CAUTION!
Failure to follow these procedures could result in
damage to the charging system of the booster vehicle
or the discharged vehicle.

Power Electronics And Battery Thermal
Management Systems — Coolant Level Check
The coolant expansion bottles provides a quick visual
method for determining that the coolant level is adequate.
With the vehicle off and coolant at ambient temperature,
the level of the coolant (antifreeze) in the bottles should be
between the bottom and top lines marked “MIN-MAX
FILL RANGE”.
As long as the vehicle operating temperature is satisfactory,
the coolant bottles need only be checked once a month.When additional coolant (antifreeze) is needed to maintain
the proper level, it should be added to the coolant bottles.
Do not overfill.
Check the Power Electronics and Battery Thermal Manage-
ment Systems coolant (antifreeze) protection every 12
months (before the onset of freezing weather, where appli-
cable).
Maintain coolant (antifreeze) concentration at a minimum
of 50% Mopar Antifreeze/Coolant 10 Year/150,000 Mile
Formula OAT (Organic Additive Technology) and
distilled/deionized water for proper corrosion protection.
Check the coolant bottles tubing for brittle rubber, crack-
ing, tears, cuts and tightness of the connection at the bottles
and radiator. Inspect the entire system for leaks.
Check the front of the A/C condenser for any accumula-
tion of bugs, leaves, etc. If dirty, clean by gently spraying
water from a garden hose vertically down the face of the
condenser.
NOTE:
DO NOT REMOVE THE COOLANT PRESSURE
CAP WHEN THE COOLING SYSTEM IS HOT.

220 SERVICING AND MAINTENANCE

WARNING!
You or others can be badly burned by hot 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 is hot.
Power Electronics And Battery Thermal
Management Systems — Cooling Pressure Caps
The caps must be fully tightened to prevent loss of coolant
(antifreeze).
The caps should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
NOTE:
•The pressure caps on the reservoirs are unique and rated
at 5 PSI (34.5 kPa).
• Use only Mopar replacement parts.
WARNING!
•The warning words “DO NOT OPEN HOT” on the
cooling system pressure cap are a safety precaution.
Never add coolant (antifreeze) when the cooling
system is overheated. Do not loosen or remove the
cap to cool an overheated cooling system. Heat
causes pressure to build up in the cooling system. To
prevent scalding or injury, do not remove the pres-
sure cap while the system is hot or under pressure.

SERVICING AND MAINTENANCE 221

WARNING!(Continued)
•Do not use a pressure cap other than the one speci-
fied for your vehicle. Personal injury or vehicle
damage may result.
Selection Of Coolant
Refer to “Fluids And Lubricants” in “Technical Specifica-
tions” for further information.
CAUTION!
•Mixing of coolant (antifreeze) other than specified
Organic Additive Technology (OAT) coolant (anti-
freeze), may result in cooling system damage and
may decrease corrosion protection. Organic Additive
Technology (OAT) coolant is different and should
not be mixed with Hybrid Organic Additive Tech-
nology (HOAT) coolant (antifreeze). If a non-OAT
coolant (antifreeze) is introduced into the cooling
system in an emergency, it should be replaced with
the specified coolant (antifreeze) as soon as possible.
(Continued)
CAUTION! (Continued)
•Do not use water alone or alcohol-based coolant
(antifreeze) products. Do not use additional rust
inhibitors or antirust products, as they may not be
compatible with the radiator coolant and may plug
the radiator.
• This vehicle has not been designed for use with
propylene glycol-based coolant (antifreeze). Use of
propylene glycol-based coolant (antifreeze) is not
recommended.
Adding Coolant
Your vehicle has been built with cooling systems that allow
extended maintenance intervals. This coolant (antifreeze)
can be used up to ten years or 150,000 miles (240,000 km)
before replacement. To prevent reducing this extended
maintenance period, it is important that you use the same
coolant (antifreeze) throughout the life of your vehicle.
Please review these recommendations for using Organic
Additive Technology (OAT) coolant (antifreeze).

containers or allow it to remain in puddles on the ground.
If ingested by a child, contact a physician immediately.
Clean up any ground spills immediately.
Points To Remember
WARNING!
•Turn vehicle OFF and disconnect the fan motor lead
before working near the radiator cooling fan.
• You or others can be badly burned by hot 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 open a cooling system pressure cap when the
radiator or coolant bottle is hot.
• Do not put your hands, tools, clothing, and jewelry
near the radiator cooling fan. The fan may start at any
time, whether the ignition is on or off.
If an examination of your underhood compartment shows
no evidence of cooler or hose leaks, the vehicle may be
safely driven.
• Do not overfill the coolant recovery bottles.
• Check coolant (antifreeze) freeze point in the coolant
recovery bottles. If coolant (antifreeze) needs to be added, contents of coolant recovery bottles must also be
protected against freezing.
• If frequent coolant (antifreeze) additions are required, or
if the level in the coolant recovery bottles does not drop
when the powertrain cools, the cooling system should be
pressure tested for leaks.
• Maintain coolant (antifreeze) concentration at 50% OAT
coolant (antifreeze) (minimum) and distilled/deionized
water for proper corrosion protection of your pow-
ertrain which contains aluminum components.
• Make sure that the coolant control systems recovery
bottles overflow hoses are not kinked or obstructed.
• Keep the front of the coolant control systems clean. If
your vehicle is equipped with air conditioning, keep the
front of the condenser clean.
Air Conditioner Maintenance
For best possible performance, your air conditioner should
be checked and serviced by an authorized dealer at the
start of each warm season. This service should include
cleaning of the condenser fins and air conditioning perfor-
mance tests.
