3. When the system is set up for your comfort level, itis not necessary to change the settings. You will
experience the greatest efficiency by simply allowing
the system to function automatically.
NOTE:
• It is not necessary to move the temperature settings
for cold or hot vehicles. The system automatically
adjusts the temperature, mode, and blower speed to
provide comfort as quickly as possible.
• The temperature can be displayed in U.S. or Metric
units by selecting the US/Metric customer-
programmable feature.
To provide you with maximum comfort in the Auto-
matic mode during cold start-ups, the blower fan will
remain on low until the engine warms up. The blower
will increase in speed and transition into Auto mode.
Manual Operation Override
This system offers a full complement of manual over-
ride features. The AUTO symbol in the front ATC
display will be turned off when the system is being
used in the manual mode. NOTE:
The system will not automatically sense the
presence of fog, mist or ice on the windshield. DE-
FROST mode must be manually selected to clear the
windshield and side glass.
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 overheat-
ing. OAT coolant (conforming to MS.90032) is recom-
mended. Refer to “Maintenance Procedures” in
“Maintaining Your Vehicle” for proper coolant selec-
tion.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is func-
tioning properly and the proper amount, type, and

CAUTION!(Continued)
•Your vehicle has been built with improved fluids
that protect the performance and durability of
your vehicle and also allow extended mainte-
nance intervals. Do not use chemical flushes in
these components as the chemicals can damage
them. Such damage is not covered by the New
Vehicle Limited Warranty. If a flush is needed
because of component malfunction, use only the
specified fluid for the flushing procedure.
Power Electronics And Battery Thermal
Management Systems
The Power Electronics and Battery Thermal Manage-
ment Systems are completely separate and designed to
regulate temperature for the high voltage battery and
the electric components.
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 ad-
equate. 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 satis-
factory, the coolant bottles need only be checked once a
month.
When additional coolant (antifreeze) is needed to main-
tain the proper level, it should be added to the coolant
bottles. Do not overfill.
Coolant MIN/MAX

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 Or-
ganic Additive Technology (OAT) coolant (antifreeze). When adding coolant (antifreeze):
•
The manufacturer recommends using Mopar
Antifreeze/Coolant 10 Year/150,000 Mile Formula
OAT (Organic Additive Technology).
• Mix a minimum solution of 50% OAT coolant (anti-
freeze) and distilled water. Use higher concentrations
(not to exceed 70%) if temperatures below -34ºF
(-37ºC) are anticipated.
• Use only high purity water such as distilled or
deionized water when mixing the water and coolant
(antifreeze) solution. The use of lower quality water
will reduce the amount of corrosion protection in the
cooling systems.
Please note that it is the owner ’s responsibility to
maintain the proper level of protection against freezing
according to the temperatures occurring in the area
where the vehicle is operated.
NOTE: Mixing coolant (antifreeze) types will decrease
the life of the Power Electronics and Battery Thermal
Management Systems coolant (antifreeze) and will re-
quire more frequent coolant (antifreeze) changes.

MAINTAINING YOUR VEHICLE 245

•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 re-
quired, or if the level in the coolant recovery bottles
does not drop when the engine 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 engine 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.
Maintenance-Free Battery 12 Volt
Your vehicle is equipped with a maintenance-free 12
Volt battery. You will never have to add water, nor is
periodic maintenance required.
WARNING!
• Battery fluid is a corrosive acid solution and can
burn or even blind you. Do not allow battery
fluid to contact your eyes, skin, or clothing. Do
not lean over a battery when attaching clamps. If
acid splashes in eyes or on skin, flush the area
immediately with large amounts of water. Refer
to “Jump-Starting Procedures” in “What To Do In
Emergencies” for further information.
• Battery gas is flammable and explosive. Keep
flame or sparks away from the battery. Do not use
a booster battery or any other booster source with
an output greater than 12 Volts. Do not allow
cable clamps to touch each other.
• Battery posts, terminals, and related accessories
contain lead and lead compounds. Wash hands
after handling.
• The battery in this vehicle has a vent hose that
should not be disconnected and should only be
replaced with a battery of the same type (vented).

Adding Washer Fluid
The windshield washer fluid reservoir is located in the
underhood compartment, and the fluid level should be
checked at regular intervals. Fill the reservoir with
windshield washer solvent (not coolant/antifreeze).
Refer to “Underhood Compartment” in “Maintaining
Your Vehicle” for further information.
WARNING!
Commercially available windshield washer sol-
vents are flammable. They could ignite and burn
you. Care must be exercised when filling or work-
ing around the washer solution.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically.
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure and
possibly a collision. Driving with your foot resting
or riding on the brake pedal can result in abnor-
mally high brake temperatures, excessive lining
wear, and possible brake damage. Riding the
brakes may also reduce braking capacity in an
emergency.
Brake Master Cylinder
The fluid level in the master cylinder should be checked
when performing under hood services, or immediately
if the “Brake Warning Light” is on and the parking
brake is not applied.
Be sure to clean the top of the master cylinder area
before removing the cap. If necessary, add fluid to bring
the fluid level up to the requirements described on the
brake fluid reservoir. Fluid level can be expected to fall
as the brake pads wear. The brake fluid level should be
checked when the pads are replaced. However, low
fluid level may be caused by a leak and a checkup may
be needed.7

VEHICLE STORAGE
The preferred way of storing your vehicle for a long
period of time is to leave it attached to a Level 1 or Level
2 charger. The vehicle has a wake-up feature that will
wake the system every 3 weeks and do a maintenance
charge on the 12 Volt battery and also top off the high
voltage battery if necessary. Anytime you store your vehicle, or keep it out of service
(e.g., 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 lubrication to minimize the possibility
of compressor damage when the air conditioning sys-
tem is started again.
