3. When the system is set up for your comfort level, it isnot necessary to change the settings. You 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 fea-
ture.
To provide you with maximum comfort in the Automatic
mode during cold start-ups, the blower fan remains on low
until the engine warms up. The blower increases in speed
and transition into Auto mode.Manual Operation Override
This system offers a full complement of manual override
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 pres-
ence of fog, mist or ice on the windshield. Defrost 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 conditions.
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corrosion
protection and to protect against engine overheating. OAT
coolant (conforming to MS.90032) is recommended.

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 reads
“H” pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on the “H,” turn the engine off immediately
and call an authorized dealer for service.
• A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer
for service if your vehicle overheats. If you decide to
look under the hood yourself, see “Servicing And
Maintenance.” Follow the warnings under the Cool-
ing System Pressure Cap paragraph.

WARNING!
Continued operation with reduced assist could pose a
safety risk to yourself and others. Service should be
obtained as soon as possible.
— Electronic Throttle Control (ETC) Warning
Light
This warning light will illuminate to indicate a problem
with the Electronic Throttle Control (ETC) system. If a
problem is detected while the vehicle is running, the light
will either stay on or flash depending on the nature of the
problem. Cycle the ignition when the vehicle is safely and
completely stopped and the transmission is placed in the
PARK position. The light should turn off. If the light
remains on with the vehicle running, your vehicle will
usually be drivable; however, see an authorized dealer for
service as soon as possible.
NOTE: This light may turn on if the accelerator and brake
pedals are pressed at the same time.
If the light continues to flash when the vehicle is running,
immediate service is required and you may experience reduced performance, an elevated/rough idle, or engine
stall and your vehicle may require towing. The light will
come on when the ignition is placed in the ON/RUN or
ACC/ON/RUN position and remain on briefly as a bulb
check. If the light does not come on during starting, have
the system checked by an authorized dealer.
— Engine Coolant Temperature Warning Light
This light warns of an overheated engine condition. If the
engine coolant temperature is too high, this indicator will
illuminate and a single chime will sound.
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. Refer to “If
Your Engine Overheats” in “In Case Of Emergency” for
further information.
— Hood Open Warning Light — If Equipped
This warning light will illuminate when the hood is left
open and not fully closed.
88 GETTING TO KNOW YOUR INSTRUMENT PANEL

When frequent transmission shifting occurs (such as when
operating the vehicle under heavy loading conditions, in
hilly terrain, or traveling into strong head winds), use the
AutoStick shift control (refer to AutoStick in this section for
further information) to select a lower gear. Under these
conditions, using a lower gear will improve performance
and extend transmission life by reducing excessive shifting
and heat buildup.
If the transmission temperature exceeds normal operating
limits, the transmission controller will expand the range of
torque converter clutch engagement. This is done to pre-
vent transmission damage due to overheating.
During cold temperatures, transmission operation may be
modified depending on engine coolant temperature. Nor-
mal operation will resume once the engine temperature has
risen to a suitable level.
Instrument Cluster Messages
Dedicated messages will be displayed in the instrument
cluster to alert the driver when certain unusual conditions
occur.Transmission Limp Home Mode
Transmission function is monitored electronically for ab-
normal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission remains
in a fixed gear regardless of which forward gear is selected.
The Malfunction Indicator Light (MIL) may be illuminated.
Limp Home Mode allows the vehicle to be driven to an
authorized dealer for service without damaging the trans-
mission.
In the event of a momentary problem, the transmission can
be reset to regain all forward gears by performing the
following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition OFF.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is nolonger detected, the transmission will return to normal
operation.

STARTING AND OPERATING 173

IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate action.
•On the highways — slow down.
• In city traffic — while stopped, place the transmission in
NEUTRAL, but do not increase engine idle speed.
NOTE: There are steps that you can take to slow down an
impending overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C
system adds heat to the engine cooling system and
turning the A/C off can help remove this heat.
• You can also turn the temperature control to maximum
heat, the mode control to floor and the blower control to
high. This allows the heater core to act as a supplement
to the radiator and aids in removing heat from the
engine 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
(Continued)
WARNING! (Continued)
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.
CAUTION!
Driving with a hot cooling system could damage your
vehicle. If the pointer rises to the H (red) mark, the
instrument cluster will sound a chime. When safe, pull
over and stop the vehicle with the engine at idle. Turn
off the air conditioning and wait until the pointer
drops back into the normal range. If the pointer
remains on the H (red) mark for more than a minute,
turn the engine off immediately and call for service.
GEAR SELECTOR OVERRIDE
If a malfunction occurs and the gear selector cannot be
moved out of the PARK position, you can use the following
procedure to temporarily move the gear selector:
1. Turn the engine OFF.
2. Firmly apply the parking brake.
216 IN CASE OF EMERGENCY

keep the engine properly tuned to assure proper catalyst
operation and prevent possible catalyst damage.
NOTE:Intentional tampering with emissions control sys-
tems can result in civil penalties being assessed against
you.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe and
abnormal catalyst overheating. If this occurs, stop the
vehicle, turn off the engine and allow it to cool. Service,
including a tune-up to manufacturer’s specifications,
should be obtained immediately.
To minimize the possibility of catalytic converter damage:
• Do not interrupt the ignition when the transmission is in
gear and the vehicle is in motion.
• Do not try to start the vehicle by pushing or towing the
vehicle.
• Do not idle the engine with any ignition components
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 open a cooling system pressure cap
when the radiator or coolant bottle is hot.
• Keep hands, tools, clothing, and jewelry away from
the radiator cooling fan when the hood is raised. The
fan starts automatically and may start at any time,
whether the engine is running or not.
• When working near the radiator cooling fan, discon-
nect the fan motor lead or turn the ignition to the
OFF mode. The fan is temperature controlled and can
start at any time the ignition is in the ON mode.
Coolant Checks
Check engine coolant (antifreeze) protection every 12
months (before the onset of freezing weather, where appli-
cable). If the engine coolant (antifreeze) is dirty or rusty in
appearance, the system should be drained, flushed and
refilled with fresh engine coolant (antifreeze). Check the
front of the A/C condenser for any accumulation of bugs,
242 SERVICING AND MAINTENANCE

Adding Coolant
Your vehicle has been built with an improved engine
coolant (OAT coolant conforming to MS.90032) that allows
extended maintenance intervals. This engine coolant (anti-
freeze) 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 engine coolant (OAT coolant conforming 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 (240,000 km) Formula OAT (Organic
Additive Technology) that meets the requirements of
FCA Material 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 concentrations
(not to exceed 70%) if temperatures below 34°F (37°C)
are anticipated. Please contact an authorized dealer for
assistance. •
Use only high purity water such as distilled or deionized
water when mixing the water/engine coolant (anti-
freeze) solution. The use of lower quality water will
reduce the amount of corrosion protection in the engine
cooling system.
NOTE:
• 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.
• Some vehicles require special tools to add coolant prop-
erly. 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 a local autho-
rized 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 pos-
sible.
