INSTRUMENT CLUSTER DESCRIPTIONS
1. Fuel Gauge
The fuel gauge shows the level of fuel in the fuel tank
when ignition switch is in the ON position.
2. 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 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!
Do not leave your vehicle unattended with the en-
gine running as you would not be able to react to the
temperature gauge if the engine overheats.3. Turn Signal Indicators
When a turn signal is activated, a right-pointing or
left-pointing arrow lights up and flashes to indicate the
direction of the turn. These indicators also indicate
proper operation of the front and rear turn signal lights.
If either indicator flashes at a faster rate than normal,
check for a defective bulb. If either indicator fails to light
up when the lever is moved, check for a defective fuse or
turn signal LED. A single chime is activated when the
left/right turn signal is left on, with the vehicle speed
greater than 15 mph (24 km/h) for more than 1 mile
(1.6 km).
4. Low Fuel Warning Light
The low fuel warning light will illuminate when the
fuel gauge reads 1/8 of a tank or less. There is a
pointer on the side of this symbol that indicates the
side that your fuel filler door is located.

Mode or Recirculation Mode Bi-level position. When a
comfortable condition has been reached, choose a mode
position and adjust the temperature control knob and
blower speed as necessary to maintain comfort. For high
humidity conditions it may be necessary to remain in the
Recirculation mode to maintain comfort.
Window Fogging
Windows will fog on the inside when the humidity inside
the vehicle is high. This often occurs in mild or cool
temperatures when it’s rainy or humid. In most cases
turning on the Air-conditioning (pressing the SNOW-
FLAKE button) will clear the fog. Adjust the temperature
control, air direction and blower speed to maintain
comfort.
As the temperature gets colder it may be necessary to
direct air onto the windshield by using MIX Mode
position on the control. Adjust the temperature control
and blower speed to maintain comfort. High blowerspeeds will reduce fogging. Interior fogging on the
windshield can be quickly removed by selecting the
defrost mode.
Regular cleaning of the inside of the windows with a
non-filming cleaning solution (vinegar and water works
very well) will help prevent contaminates (cigarette
smoke, perfumes, etc.) from sticking to the windows.
Contaminates on the inside of windows can increase the
rate of window fogging.
Summer Operation
Air conditioned vehicles must be protected with a high
quality antifreeze coolant during summer, to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50%
concentration of engine coolant to distilled water is
recommended. Refer to “Cooling System” under “Main-
tenance Procedures” in “Maintaining Your Vehicle”.

gear (Overdrive). The transmission will automatically
shift from Drive to Overdrive, if the following conditions
are present:
•the shift lever is in DRIVE;
•the engine coolant has reached normal operating tem-
perature;
•vehicle speed is above approximately 30 mph
(48 km/h);
•the TOW/HAUL switch has not been activated;
•transmission has reached normal operating
temperature.
NOTE:
•If the vehicle is started in extremely cold temperatures,
the transmission may not shift into Overdrive and will automatically select the most desirable gear for opera-
tion at this temperature. Normal operation will re-
sume when the transmission fluid temperature has
risen to a suitable level. Refer to “Torque Converter
Clutch” in this section.
•If the transmission temperature gets extremely hot, the
transmission will automatically select the most desir-
able gear for operation at this temperature. If the
transmission temperature becomes hot enough, the
“Transmission Temperature Warning Light” may illu-
minate and the transmission may downshift out of
Overdrive until the transmission cools down. After
cool down, the transmission will resume normal
operation.
The transmission will downshift from Overdrive to
DRIVE if the accelerator pedal is fully pressed at vehicle
speeds above approximately 35 mph (56 km/h).

STARTING AND OPERATING 255
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.
•Mix a minimum solution of 50% HOAT engine coolant
(antifreeze) and distilled water. Use higher concentra-
tions (not to exceed 70%) if temperatures below -34° F
(-37° C) are anticipated.
•Use only high purity water such as distilled or deion-
ized 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.Please note that it is the owner’s responsibility to main-
tain the proper level of protection against freezing ac-
cording to the temperatures occurring in the area where
the vehicle is operated.
NOTE:
Mixing engine coolant (antifreeze) types will
decrease the life of the engine coolant (antifreeze) and
will require more frequent engine coolant (antifreeze)
changes.
Cooling System Pressure Cap
The cap must be fully tightened to prevent the loss of
engine coolant (antifreeze), and to ensure that the engine
coolant (antifreeze) will return to the radiator from the
coolant recovery bottle.
The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.

MAINTAINING YOUR VEHICLE 371
WARNING!
•The warning words “DO NOT OPEN HOT” on
the cooling system pressure cap are a safety pre-
caution. Never add engine coolant (antifreeze)
when the engine is overheated. 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 remove 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 en-
gine damage may result.
Disposal of Used Engine Coolant
Used ethylene glycol-based engine coolant (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 ani-
mals 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 recovery bottle provides a quick visual
method for determining that the engine coolant (anti-
freeze) level is adequate. With the engine cold, the level
of the engine coolant (antifreeze) in the coolant recovery
bottle should be between the ranges indicated on the
bottle.
372 MAINTAINING YOUR VEHICLE
The radiator normally remains completely full, so there is
no need to remove the radiator cap unless checking for
the engine coolant (antifreeze) freeze point or replacing
the engine coolant (antifreeze). Advise your service at-
tendant of this. As long as the engine operating tempera-
ture is satisfactory, the coolant recovery bottle need only
be checked once a month.
When additional engine coolant (antifreeze) is needed to
maintain the proper level, it should be added to the
coolant recovery bottle. Do not overfill.
Points to Remember
NOTE:When the vehicle is stopped after a few miles
(kilometers) of operation, you may observe vapor coming
from the front of the engine compartment. This is nor-
mally a result of moisture from rain, snow, or high
humidity accumulating on the radiator and being vapor-
ized when the thermostat opens, allowing hot coolant to
enter the radiator. If an examination of your engine compartment shows no
evidence of radiator or hose leaks, the vehicle may be
safely driven. The vapor will soon dissipate.
•Do not overfill the coolant recovery bottle.
•Check the coolant freeze point in the radiator and in
the coolant recovery bottle. If antifreeze needs to be
added, the contents of the coolant recovery bottle must
also be protected against freezing.
•If frequent engine coolant (antifreeze) additions are
required, or if the level in the coolant recovery bottle
does not drop when the engine cools, the cooling
system should be pressure tested for leaks.
•Maintain engine coolant (antifreeze) concentration at
50% HOAT engine coolant (antifreeze) (minimum)
and distilled/deionized water for proper corrosion
protection of your engine, which contains aluminum
components.
7
MAINTAINING YOUR VEHICLE 373
•Make sure that the radiator and coolant recovery
bottle overflow hoses are not kinked or obstructed.
•Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, also keep the front of
the condenser clean.
•Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory engine coolant (antifreeze)
performance, poor gas mileage, and increased
emissions.
Brake System
Fluid Level Check – Brake Master Cylinder
The fluid level in the master cylinder should be checked
whenever the vehicle is serviced, or immediately if the
“Brake Warning Light” is on. If necessary, add fluid to
bring level to the full mark on the side of the reservoir of
the brake master cylinder. Be sure to clean the top of the
master cylinder area before removing the cap. With disc
brakes, the fluid level can be expected to fall as the brake
pads wear. Brake fluid level should be checked when
pads are replaced. If the brake fluid level is abnormally
low, check the system for leaks.
Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information.
374 MAINTAINING YOUR VEHICLE
•Check the fluid levels of the coolant reservoir, brake
master cylinder, power steering and transmission, and
add as needed.
•Check all lights and other electrical items for correct
operation.
At Each Oil Change
•Change the engine oil filter.
•Inspect the brake hoses and lines.
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
