1. Tachometer•Indicates the engine speed in revolutions per minute
(RPM x 1000).
2. Instrument Cluster Display •When the appropriate conditions exist, this display
shows the Instrument Cluster Display messages. Refer
to “Instrument Cluster Display” in “Understanding
Your Instrument Panel” for further information.
3. Speedometer •Indicates vehicle speed.
4. Fuel Gauge •The pointer shows the level of fuel in the fuel tank
when the ignition is in the ON/RUN position.
•
The fuel pump symbol points to the side of the
vehicle where the fuel door is located.
5. Temperature Gauge
•The temperature gauge shows engine coolant tem-
perature. Any reading within the normal range indi-
cates that the engine cooling system is operating
satisfactorily. •
The gauge pointer will likely indicate a higher tem-
perature 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.
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 an authorized dealer for
service if your vehicle overheats. If you decide to look
under the hood yourself, see “Maintaining Your Ve-
hicle”. Follow the warnings under the Cooling System
Pressure Cap paragraph.
CAUTION!
Driving with a hot engine cooling system could dam-
age 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.

panel together with a dedicated message and/or acoustic
signal when applicable. These indications are indicative
and precautionary and as such must not be considered as
exhaustive and/or alternative to the information contained
in the Owner ’s Manual, which you are advised to read
carefully in all cases. Always refer to the information in this
chapter in the event of a failure indication.
All active telltales will display first if applicable. The
system check menu may appear different based upon
equipment options and current vehicle status. Some tell-
tales are optional and may not appear.

HAZARD WARNING FLASHERS
The Hazard Warning flasher switch is located on the upper
switch bank just below the radio.Push 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. Push 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 assistance, the
Hazard Warning flashers will continue 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 increase the engine idle speed
while preventing vehicle motion with the brakes.
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.
580 WHAT TO DO IN EMERGENCIES

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.
CAUTION!
Driving with a hot cooling system could damage your
vehicle. If the temperature gauge reads HOT (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 HOT
(H), and you hear continuous chimes, turn the engine
off immediately and call for service.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure that
the wheel is properly mounted to the vehicle. Any time a
wheel has been removed and reinstalled on the vehicle, the
lug nuts/bolts should be torqued using a properly cali-
brated torque wrench.

Air Conditioner Maintenance
For best possible performance, your air conditioner should
be checked and serviced by an authorized dealer at the
start of each warm season. This service should include
cleaning of the condenser fins and a performance test.
Drive belt tension should also be checked at this time.
WARNING!
•Use only refrigerants and compressor lubricants ap-
proved by the manufacturer for your air conditioning
system. Some unapproved refrigerants are flam-
mable and can explode, injuring you. Other unap-
proved refrigerants or lubricants can cause the sys-
tem to fail, requiring costly repairs. Refer to
Warranty Information Book, located on the DVD, for
further warranty information.
• The air conditioning system contains refrigerant un-
der high pressure. To avoid risk of personal injury or
damage to the system, adding refrigerant or any
repair requiring lines to be disconnected should be
done by an experienced technician.
CAUTION!
Do not use chemical flushes in your air conditioning
system as the chemicals can damage your air condition-
ing components. Such damage is not covered by the
New Vehicle Limited Warranty.
Refrigerant Recovery And Recycling R134a —
If Equipped
R-134a Air Conditioning Refrigerant is a hydrofluoro-
carbon (HFC) that is endorsed by the Environmental
Protection Agency and is an ozone-saving product. How-
ever, the manufacturer recommends that air conditioning
service be performed by authorized dealer or other service
facilities using recovery and recycling equipment.
NOTE: Use only manufacturer approved A/C system PAG
compressor oil and refrigerants.

•For tough stains, apply MOPAR Total Clean, or a mild
soap solution to a clean, damp cloth and remove stain.
Use a fresh, damp towel to remove soap residue.
• For grease stains, apply MOPAR Multi-Purpose Cleaner
to a clean, damp cloth and remove stain. Use a fresh,
damp towel to remove soap residue.
• Do not use any harsh solvents or any other form of
protectants on Stain Repel products.
Interior Care
Use MOPAR Total Clean to clean fabric upholstery and
carpeting.
Use MOPAR Total Clean to clean vinyl upholstery.
MOPAR Total Clean is specifically recommended for
leather upholstery.
Your leather upholstery can be best preserved by regular
cleaning with a damp soft cloth. Small particles of dirt can
act as an abrasive and damage the leather upholstery and
should be removed promptly with a damp cloth. Stubborn
soils can be removed easily with a soft cloth and MOPAR
Total Clean. Care should be taken to avoid soaking your
leather upholstery with any liquid. Please do not use
polishes, oils, cleaning fluids, solvents, detergents, or ammonia-based cleaners to clean your leather upholstery.
Application of a leather conditioner is not required to
maintain the original condition.
WARNING!
Do not use volatile solvents for cleaning purposes.
Many are potentially flammable, and if used in closed
areas they may cause respiratory harm.
CAUTION!
Direct contact of air fresheners, insect repellents, sun-
tan lotions, or hand sanitizers to the plastic, painted, or
decorated surfaces of the interior may cause permanent
damage. Wipe away immediately.
CAUTION!
Damage caused by these type of products may not be
covered by your New Vehicle Limited Warranty.
