experience the greatest efficiency by simply allowing
the system to function automatically.
• 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-
To provide you with maximum comfort in the Auto-

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.

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-
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is func-

If the coolant (antifreeze) is dirty or contains a consid-
erable amount of sediment, clean and flush with a
reliable cooling system cleaner. Follow with a thorough
rinsing to remove all deposits and chemicals. Properly
dispose of old coolant (antifreeze) solution.
It is recommended to have the cooling systems
serviced at your authorized dealer. Failure to do so
could result in poor cooling system performance
and/or vehicle damage.
Disposal Of Used Power Electronics And
Battery Thermal Management Systems Coolant
Used 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 animals or children, do not store
antifreeze in open containers or allow it to remain inpuddles on the ground. If ingested by a child, contact a
physician immediately. Clean up any ground spills
Points To Remember
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 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 open a cooling system
pressure cap when the radiator or coolant bottle is
• Keep hands, tools, clothing, and jewelry away
from the radiator cooling fan when the hood is
raised. The fan may start without warning,
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 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.
• 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
• 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).
