25. Temperature Gauge
The temperature gauge shows engine coolant
temperature. Any reading within the normal
range indicates that the engine cooling system
is operating satisfactorily. The gauge pointer will likely indicate a higher
temperature when driving in hot weather, up
mountain grades, or when towing a trailer. It
should not be allowed to exceed the upper limits
of the normal operating range.
CAUTION!
Driving with a hot engine cooling system
could damage your vehicle. If the tempera-
ture gauge reads “H” pull over and stop the
vehicle. Idle the vehicle with the air condi-
tioner turned off until the pointer drops back
into the normal range. If the pointer remains
on the “H” and you hear continuous chimes,
turn the engine off immediately and call an
authorized dealer for service.

Engine Idling – In Cold Weather
Avoid prolonged idling in ambient temperatures
below 0°F (-18°C). Long periods of idling may
be harmful to your engine because combustion
chamber temperatures can drop so low that the
fuel may not burn completely. Incomplete com-
bustion allows carbon and varnish to form on
piston rings and injector nozzles. Also, the
unburned fuel can enter the crankcase, diluting
the oil and causing rapid wear to the engine.
Stopping The Engine
Before turning off your turbo diesel engine,
always allow the engine to return to normal idle
speed and run for several seconds. This as-
sures proper lubrication of the turbocharger.
This is particularly necessary after any period of
hard driving.
Idle the engine a few minutes before routine
shutdown. After full load operation, idle the
engine three to five minutes before shutting it
down. This idle period will allow the lubricating
oil and coolant to carry excess heat away from
the combustion chamber, bearings, internal
components, and turbocharger. This is espe-
cially important for turbocharged, charge air
cooled engines.AUTOMATIC TRANSMISSION
CAUTION!
Damage to the transmission may occur if the
following precautions are not observed:
•Shift into PARK only after the vehicle has
come to a complete stop.
• Shift into or out of REVERSE only after the
vehicle has come to a complete stop and
the engine is at idle speed.
• Do not shift between PARK, REVERSE,
NEUTRAL, or DRIVE when the engine is
above idle speed.
•
Before shifting into any gear, make sure your
foot is firmly pressing the brake pedal.
NOTE:
You must press and hold the brake pedal
while shifting out of PARK.
WARNING!
• Unintended movement of a vehicle could
injure those in or near the vehicle. As with
all vehicles, you should never exit a ve-
hicle while the engine is running. Before
exiting a vehicle, always apply the parking
brake, shift the transmission into PARK,
turn the engine OFF, and remove the key
fob. When the ignition is in the OFF posi-
tion, the shift lever is locked in PARK,
securing the vehicle against unwanted
movement.
• It is dangerous to shift out of PARK or
NEUTRAL if the engine speed is higher
than idle speed. If your foot is not firmly
pressing the brake pedal, the vehicle could
accelerate quickly forward or in reverse.
You could lose control of the vehicle and
hit someone or something. Only shift into
gear when the engine is idling normally
and your foot is firmly pressing the brake
pedal.

Overdrive Operation
The automatic transmission includes an elec-
tronically controlled Overdrive (fourth and fifth
gears). The transmission will automatically shift
into Overdrive if the following conditions are
present:
•the shift lever is in the DRIVE position,
• the transmission fluid has reached an ad-
equate temperature,
• the engine coolant has reached an adequate
temperature,
• vehicle speed is sufficiently high,
• the driver is not heavily pressing the accel-
erator, and
•
the TOW/HAUL switch has not been activated.
When To Use TOW/HAUL Mode
When driving in hilly areas, towing a trailer,
carrying a heavy load, etc., and frequent trans-
mission shifting occurs, press the TOW/HAUL
switch to activate TOW/HAUL mode. This will
improve performance and reduce the potential
for transmission overheating or failure due to
excessive shifting. When operating in TOW/ HAUL mode, transmission upshifts are delayed,
and the transmission will automatically down-
shift (for engine braking) during steady braking
maneuvers.
The “TOW/HAUL Indicator Light” will illuminate
in the instrument cluster to indicate that TOW/
HAUL mode has been activated. Pressing the
switch a second time restores normal operation.
Normal operation is always the default at en-
gine start-up. If TOW/HAUL mode is desired,
the switch must be pressed each time the
engine is started.
Torque Converter Clutch
A feature designed to improve fuel economy
has been included in the automatic transmis-
sion on your vehicle. A clutch within the torque
converter engages automatically at calibrated
speeds. This may result in a slightly different
feeling or response during normal operation in
the upper gears. When the vehicle speed drops
or during some accelerations, the clutch auto-
matically disengages.
NOTE:
•
The torque converter clutch will not en-
gage, and the transmission will not shift
into the top overdrive gear, until the trans-
mission fluid and engine coolant are
warm [usually after 1 to 3 miles (2 to 5 km)
of driving]. Because top gear is disabled,
and engine speed is higher when the
torque converter clutch is not engaged, it
may seem as if the transmission is not
shifting properly when cold. This is nor-
mal. Using the Electronic Range Select
(ERS) shift control, when the transmis-
sion is sufficiently warm, will demon-
strate that the transmission is able to shift
into and out of Overdrive.

HAZARD WARNING FLASHERS
The Hazard Warning flasher switch is located
on the switch bank just above the climate
controls.Press the switch to turn on the Hazard
Warning flasher. When the switch is
activated, all directional turn signals
will flash on and off to warn oncoming traffic of
an emergency. Press the switch a second time
to turn off the Hazard Warning flashers.
This is an emergency warning system and it
should not be used when the vehicle is in
motion. Use it when your vehicle is disabled and
it is creating a safety hazard for other motorists.
When you must leave the vehicle to seek assis-
tance, the Hazard Warning flashers will con-
tinue to operate even though the ignition is
placed in the OFF position.
NOTE:
With extended use the Hazard Warning
flashers may wear down your battery.
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 in-
crease the 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 supple-
ment to the radiator and aids in removing
heat from the engine cooling system.CAUTION!
Driving with a hot cooling system could dam-
age your vehicle. If the temperature gauge
reads HOT (H), pull over and stop the ve-
hicle. Idle the vehicle with the air conditioner
turned off until the pointer drops back into the
normal range. If the pointer remains on
HOT (H), and you hear continuous chimes,
turn the engine off immediately and call for
service.
WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam com-
ing 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.

NOTE:
Intentional tampering with emissions con-
trol systems can result in civil penalties
being assessed against you.
In unusual situations involving grossly malfunc-
tioning engine operation, a scorching odor may
suggest severe and abnormal catalyst over-
heating. If this occurs, stop the vehicle, turn off
the engine and allow it to cool. Service, includ-
ing a tune-up to manufacturer’s specifications,
should be obtained immediately.
To minimize the possibility of catalytic converter
damage:
•Do not shut off the engine or interrupt the
ignition, when the transmission is in gear and
the vehicle is in motion.
• Do not try to start the engine by pushing or
towing the vehicle.
• 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 malfunction-
ing 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 com-
ing 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) protec-
tion every 12 months (before the onset of
freezing weather, where applicable). If the en-
gine coolant (antifreeze) is dirty, the system
should be drained, flushed, and refilled with
fresh OAT coolant (conforming to MS-12106) 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 tight-
ness 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 pres-
sure 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 (antifreeze) will begin
to drain from the coolant recovery bottle. DO NOT
REMOVE THE COOLANT PRESSURE CAP
WHEN THE COOLING SYSTEM IS HOT.
Cooling System – Drain, Flush, And Refill
If the engine coolant (antifreeze) is dirty or
contains visible sediment, clean and flush with
OAT coolant (antifreeze) that meets the require-
ments of Chrysler Material Standard MS-12106.
Refer to the “Maintenance Schedule” for the
proper maintenance intervals.
321

Selection Of Coolant
Refer to “Fluids, Lubricants, and Genuine Parts”
in “Maintaining Your Vehicle” for further informa-
tion.
CAUTION!
•
Mixing of engine coolant (antifreeze) other
than specified Organic Additive Technology
(OAT) engine coolant (antifreeze), may re-
sult in engine damage and may decrease
corrosion protection. Organic Additive Tech-
nology (OAT) engine coolant is different and
should not be mixed with Hybrid Organic
Additive Technology (HOAT) engine coolant
(antifreeze) or any “globally compatible”
coolant (antifreeze). If a non-OAT engine
coolant (antifreeze) is introduced into the
cooling system in an emergency, it should be
flushed with OAT coolant and replaced with
the specified OAT engine coolant (anti-
freeze) as soon as possible.
(Continued)
CAUTION!(Continued)
•Do not use water alone or alcohol-based
engine coolant (antifreeze) products. Do
not use additional 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 cool-
ant (antifreeze). Use of propylene glycol-
based engine coolant (antifreeze) is not
recommended.
Adding Coolant
Your vehicle has been built with an improved
engine coolant (OAT coolant conforming to
MS-12106) that allows extended maintenance
intervals. This engine 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 engine coolant
(OAT coolant conforming to MS-12106) through-
out the life of your vehicle.
Please review these recommendations for us-
ing Organic Additive Technology (OAT) engine
coolant (antifreeze) that meets the require-
ments of Chrysler Material Standard MS-12106.
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 Chrysler Material Standard
MS-12106.
• Mix a minimum solution of 50% OAT engine
coolant that meets the requirements of
Chrysler Material Standard MS-12106 and
distilled water. Use higher concentrations
(not to exceed 70%) if temperatures below
34° F (37° C) are anticipated.
• Use only high purity water such as distilled or
deionized 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.
322

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 engine coolant (antifreeze) types is
not recommended and can result in cooling
system damage. Drain, flush, and refill as
soon as possible to avoid damage if coolant
types are mixed in an emergency.
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!
•The warning words “DO NOT OPEN HOT”
on the cooling system pressure cap are a
safety precaution. Never add engine cool-
ant (antifreeze) when the engine is over-
heated. 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 re-
move the pressure cap while the system is
hot or under pressure.
• Do not use a pressure cap other than the
one specified for your vehicle. Personal
injury or engine damage may result.
Disposal Of Used Engine Coolant
Used ethylene glycol-based engine coolant (an-
tifreeze) is a regulated substance requiring
proper disposal. Check with your local authori-
ties to determine the disposal rules for your
community. To prevent ingestion by animals or
children, do not store ethylene glycol-based
engine coolant (antifreeze) 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 bottle provides a quick visual
method for determining that the coolant level is
adequate. With the engine OFF and cold, the
level of the engine coolant (antifreeze) in the
bottle should be between the ranges indicated
on the bottle.
The radiator normally remains completely full,
so there is no need to remove the radiator cap
unless checking for engine coolant (antifreeze)
freeze point or replacing coolant. Advise your
service attendant of this. As long as the engine
operating temperature is satisfactory, the cool-
ant bottle need only be checked once a month.
When additional engine coolant (antifreeze) is
needed to maintain the proper level, only OAT
coolant that meets the requirements of Chrysler
Material Standard MS-12106 should be added
to the coolant bottle. Do not overfill.
