WARNING! (Continued)
•Always make sure that objects cannot fall into the
driver footwell while the vehicle is moving. Objects
can become trapped under the brake pedal and
accelerator pedal causing a loss of vehicle control.
•If required, mounting posts must be properly
installed, if not equipped from the factory.
Failure to properly follow floor mat installation or
mounting can cause interference with the brake
pedal and accelerator pedal operation causing loss
of control of the vehicle.
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cutsand cracks. Inspect sidewalls for cuts, cracks and bulges.
Check the wheel nuts for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Door Latches
Check for positive closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid, or
brake fluid leaks are suspected, the cause should be
located and corrected immediately.
84 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

7. Electronic Throttle Control (ETC) Warning LightThis light will turn on briefly as a bulb check
when the ignition switch is placed in ON/
RUN. This light will also turn on while the
engine is running if there is a problem with the
Electronic Throttle Control (ETC) system.
If the light comes on while the engine is running, safely
bring the vehicle to a complete stop as soon as possible,
place the shift lever in PARK, and cycle the ignition key. The
light should turn off. If the light remains lit with the engine
running, your vehicle will usually be drivable. However,
see an authorized dealer for service as soon as possible.
If the light is flashing when the engine is running,
immediate service is required. In this case, you may
experience reduced performance, an elevated/rough idle
or engine stall, and your vehicle may require towing.
Also, have the system checked by an authorized dealer if
the light does not come on during starting. 8. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.
The gauge pointer will likely indicate a higher tempera-
ture 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 cooling system could damage
your vehicle. If the temperature gauge reads 240°F
(116°C) or greater, pull over and stop the vehicle. Idle
the vehicle with the air conditioner turned off until
the pointer drops back into the normal range 200–
230°F (93–110°C). If the pointer remains at 240°F
(116°C) or greater and you hear a chime, turn the
engine OFF immediately and call for service.

WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call a service center if your
vehicle overheats. If you decide to look under the
hood yourself, refer to “Maintaining Your Vehicle”
and follow the warnings under the Cooling System
Pressure Cap paragraph.
9. Turn Signal Indicators The arrow will flash with the exterior turn signal
when the turn signal lever is operated.
NOTE:
•A continuous chime will sound if the vehicle is driven
more than 1 mile (1.6 km) with either turn signal on.
•Check for an inoperative outside light bulb if either
indicator flashes at a rapid rate. 10. Air Bag Warning Light
This light will turn on for four to eight seconds
as a bulb check when the ignition switch is first
turned to the ON/RUN position. If the light is
either not on during starting, stays on, or turns
on while driving, have the system inspected at an autho-
rized dealer as soon as possible. Refer to “Occupant
Restraints” in “Things To Know Before Starting Your
Vehicle” for further information.
11. Engine Temperature Warning Light This light will turn on and a single chime will
sound to warn of an overheated engine condition.
When this light turns on, the engine temperature
is critically hot. The vehicle should be turned OFF
immediately and serviced as soon as possible.

•Most of the time, when in Automatic Operation, you
can temporarily put the system into Recirculation
Mode by pressing the Recirculation button. However,
under certain conditions, while in Automatic Mode,
the system is blowing air out the defrost vents. When
these conditions are present, and the Recirculation
button is pressed, the indicator will flash and then turn
off. This tells you that you are unable to go into
Recirculation Mode at this time. If you would like the
system to go into Recirculation Mode, you must first
move the Mode knob to Panel, Panel/Floor and then
press the Recirculation button. This feature reduces the
possibility of window fogging.
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 in air-conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. A solution of 50% ethylene
glycol antifreeze coolant and 50% water is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant selection.
Winter Operation
Use of the air Recirculation Mode during winter months is
not recommended because it may cause window fogging.
Vacation Storage
Anytime you store your vehicle, or keep it out of service
(i.e., vacation) for two weeks or more, run the air
conditioning system at idle for about five minutes in the
fresh air and high blower settings. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.

Earlier upshifts during cruise conditions (relatively
steady speeds) may result in increased fuel economy.
Higher upshift speeds may be used to obtain a desired
acceleration rate.
NOTE:
•Your vehicle is equipped with a transmission reverse
inhibitor system. When vehicle speed is greater than
3 mph (5 km/h), the reverse inhibitor activates to help
prevent shifts into REVERSE. When at a complete
stop, you may notice lighter shift efforts into REVERSE
with the ignition switch in the ON position (RUN
position for Keyless Enter-N-Go) as compared to the
LOCK position (OFF position for Keyless Enter-N-Go).
This is normal operation of the transmission reverse
inhibitor system.
•Due to the high performance nature of your drivetrain,
you may hear your transmission. This can be most
noticeable when the vehicle is idling in NEUTRAL withthe clutch engaged (clutch pedal released), but it may
also be heard when driving at low engine RPM. Also,
this may be more noticeable when the transmission is
warm. This is a normal condition and is not an indica-
tion of a problem with your clutch or transmission.
1–4 Skip Shift
There are times when you must shift the transmission
directly from first gear to fourth gear instead of from first
gear to second gear. This is to help you get the best
possible fuel economy from your vehicle. This occurs
when the engine coolant (antifreeze) is higher than 106°F
(41°C), vehicle speed is greater than 19 mph (30 km/h)
but less than 21 mph (34 km/h), and the transmission is
in first gear, and the accelerator is at 1/4 throttle or less.
The “1–4 Skip Shift Indicator Message” will be displayed
during these times.
266 STARTING AND OPERATING

•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.
CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads 240°F
(116 °C) or greater pull over and stop the vehicle. Idle
the vehicle with the air conditioner turned off until
the pointer drops back into the normal range 200–
230°F (93–110°C). If the pointer remains at 240°F
(116°C) or greater and you hear a chime, 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 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 or coolant bottle is hot.
TIREFIT KIT
Small punctures up to14in (6 mm) in the tire tread can be
sealed with TIREFIT. Foreign objects (e.g., screws or
nails) should not be removed from the tire. TIREFIT can
be used in outside temperatures down to approximately
-4°F (-20°C).
This kit will provide a temporary tire seal, allowing you
to drive your vehicle up to 100 miles (160 km) with a
maximum speed of 55 mph (88 km/h).6

366 MAINTAINING YOUR VEHICLE

To minimize the possibility of catalytic converter dam-
age:
•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 malfunctioning operating conditions.
Cooling System
WARNING!
•When working near the radiator cooling fan, dis-
connect the fan motor lead or turn the ignition
switch to the LOCK position (OFF position for
Keyless Enter-N-Go). The fan is temperature con-
trolled and can start at any time the ignition switch
is in the ON position (RUN position for Keyless
Enter-N-Go).
•You or others can be badly burned by hot coolant
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.

Coolant Checks
Check the engine coolant (antifreeze) protection every
12 months (before the onset of freezing weather, where
applicable). If coolant is dirty or rusty in appearance, the
system should be drained, flushed, and refilled with
fresh coolant. 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 coolant recovery bottle tubing for brittle rub-
ber, cracking, tears, cuts, and tightness of the connection
at the bottle and radiator. Inspect the entire system for
leaks.
With the engine at normal operating temperature (but
not running), check the cooling system pressure cap for
proper vacuum sealing by draining a small amount of
coolant from the radiator drain cock. If the cap is sealing
properly, the engine coolant (antifreeze) will begin todrain from the coolant recovery bottle. DO NOT RE-
MOVE THE COOLANT PRESSURE CAP WHEN THE
COOLING SYSTEM IS HOT.
Cooling System – Drain, Flush, And Refill
If the solution is dirty or contains a considerable 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 the old
antifreeze solution.
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
Selection Of Coolant
Use only the manufacturer’s recommended coolant.
Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information.
384 MAINTAINING YOUR VEHICLE

CAUTION!
•Mixing of coolants other than specified HOAT
engine coolants may result in engine damage and
may decrease corrosion protection. If a non-HOAT
coolant is introduced into the cooling system in an
emergency, it should be replaced with the speci-
fied coolant as soon as possible.
•Do not use plain 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 coolants. Use of propylene
glycol-based coolants is not recommended.
Adding Coolant
Your vehicle has been built with an improved engine
coolant (antifreeze) that allows extended maintenance
intervals. This engine coolant (antifreeze) can be used up
to five years or 102,000 miles (170 000 km) before
replacement. To prevent reducing this extended mainte-
nance period, it is important that you use the same
engine coolant (antifreeze) throughout the life of your
vehicle.
Please review these recommendations for using Hybrid
Organic Additive Technology (HOAT) engine coolant
(antifreeze). When adding engine coolant (antifreeze):
•The manufacturer recommends using MOPAR
Antifreeze/Coolant 5 Year/100,000 Mile Formula HOAT
(Hybrid Organic Additive Technology) or equivalent.7
