cooling CHRYSLER 300 LX 2007 Owners Manual

A new engine may consume some oil during its first few
thousand miles (kilometers) of operation. This should be
considered as a normal part of the break-in and not
interpreted as an indication of difficulty.
SAFETY TIPS
Transporting Passengers
NEVER TRANSPORT PASSENGERS IN THE CARGO
AREA.
WARNING!
It is extremely dangerous to ride in a cargo area,
inside or outside of a vehicle. In a collision, people
riding in these areas are more likely to be seriously
injured or killed.
Do not allow people to ride in any area of your
vehicle that is not equipped with seats and seat belts.
Be sure everyone in your vehicle is in a seat and
using a seat belt properly.
Lock Your Vehicle
Always remove the keys from the ignition and lock all
doors when leaving the vehicle unattended, even in your
own driveway or garage. Try to park your vehicle in a
well-lit area and never invite theft by leaving articles of
value exposed.
Exhaust Gas
Do not run the engine in a closed garage or in confined
areas any longer than needed to move your vehicle in or
out of the area.
If it is necessary to sit in a parked vehicle with the engine
running, adjust your heating or cooling controls to force
outside air into the vehicle. Set the blower at high speed.
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle is
damaged, have a competent mechanic inspect the com-
plete exhaust system and adjacent body areas for broken,

turn on in the event of an EBD failure. Immediate repair
of the ABS system is required in the event of an EBD
failure.
The operation of the Brake Warning Light can be checked
by turning the ignition switch from the OFF position to
the ON position. The light should turn on for approxi-
mately two seconds and then turn off. The light will
remain on if the parking brake is applied or if a brake
fault is detected. If the parking brake is not applied and
the light remains on, or if the light does not turn on, have
the light inspected by an authorized dealer.
NOTE:The light will turn on when the ignition switch
in the ON position and the parking brake is applied. This
light shows only that the parking brake is applied. It does
not show the degree of brake application. (See page 253
for more information.)
13. Electronic Stability Program (ESP)/Traction
Control System (TCS) Indicator Light
If this indicator light flashes during accelera-
tion, ease up on the accelerator and apply as
little throttle as possible. Adapt your speed
and driving to the prevailing road condi-
tions, and do not switch off the ESP or TCS — if
equipped. (See page 257 for more information.) (See
page 259 for more information.)
14. 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 engine cooling system could
damage your vehicle. If 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”, and you hear continuous chimes, 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, see Section 7 of this manual. Follow
the warnings under the Cooling System Pressure
Cap paragraph.

the controls on the climate control, from a dual sun-
sensor located in the top of the instrument panel, from an
infrared sensor located in the face of the climate control,
and from various sensors located throughout the vehicle.
The controls on the climate control provide the system
with operator input. The dual sun-sensor monitors sun
load coming through the windshield. The infrared sensor
independently measures the surface temperature of the
driver and passenger. Other sensors take account of
vehicle-speed, A/C pressure, outside temperature, and
engine cooling temperature. Using all of these inputs, the
system automatically adjusts airflow temperature, air-
flow distribution, airflow volume, and the amount of
outside air recirculation. This maintains a comfortable
temperature even under changing conditions.
Operation of the system is quite simple. Begin by turning
the Mode Control knob (on the right) to AUTO, and place
the Blower Control knob (on the left) to either LO AUTO
or HI AUTO. The LO AUTO position should be used for
front seat occupants only. The HI AUTO position should
be used when more airflow is desired, or when rear seat
occupants are present. Then, dial in the temperature youwould like the system to maintain by rotating the driver
or passenger Temperature Control knob. Once the com-
fort level is selected, the system will maintain that level
automatically using the heating system. Should the de-
sired comfort level require air conditioning, the system
will automatically make the adjustment.
You will experience the greatest efficiency by simply
allowing the system to function automatically. Selecting
the OFF position on the fan control stops the system
completely and closes the outside air intake.
72°F (22°C) is the recommended setting for maximum
comfort for the average person; however, this may vary.
NOTE:The temperature setting can be adjusted at any
time without affecting automatic operation.
Air conditioning in this system is automatic.
Pressing the Air Conditioning Control button
while in AUTO mode will cause the LED in the
control button to flash three times and then turn off.
This indicates that the system is in AUTO mode and
requesting the air conditioning is not necessary.
222 UNDERSTANDING YOUR INSTRUMENT PANEL

NOTE:To control the air conditioning manually, the
mode selector must be moved out of the AUTO position.
•Recirculation Control
This button can be used to block out smoke,
odors, dust, high humidity, or if rapid cooling
is desired. The recirculation mode should only
be used temporarily. An LED in the button
illuminates when the recirculation mode is active. You
may use this feature separately.
NOTE:Extended use of recirculation may cause the
windows to fog. If the interior of the windows begins to
fog, press the Recirculation button to return to outside
air. Some temp/humidity conditions will cause captured
interior air to condense on windows and hamper visibil-
ity. For this reason, the system will not allow Recircula-
tion to be selected while in defrost or defrost/floor mode.
Attempting to use the recirculation while in these modes
will cause the LED in the control button to blink and then
turn off.
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 50% solution of ethylene
glycol antifreeze coolant in water is recommended. Refer
to “Maintenance Procedures” in Section 7 of this manual
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 condi-
tioning system at idle for about five minutes in the fresh
air and high blower setting. This will insure adequate

Towing Tips — Autostick(If Equipped)

For vehicles equipped with Autostick.By using the
Autostickmodes, and selecting a specific gear range,
frequent shifting can be avoided. The highest gear
range should be selected that allows for adequate
performance. For example, choose “4” if the desired
speed can be maintained. Choose “3” or “2” if needed
to maintain the desired speed.
Extended driving at high RPM should be avoided to
prevent excess heat generation. A reduction in vehicle
speed may be required to avoid extended driving at
high RPM. Return to a higher gear range or vehicle
speed when road conditions and RPM level allows.
Towing Tips — Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods, put transmission in
neutral and increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
Refer to “Cooling System” under “Maintenance Pro-
cedures” in Section 7 of this manual for more informa-
tion.
RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.)
TOWING THIS VEHICLE BEHIND ANOTHER
VEHICLE (Flat towing with all four wheels on the
ground)
Recreational towing for this vehicle is not recommended.
NOTE:If the vehicle requires towing, make sure all
four wheels are off the ground.
STARTING AND OPERATING 309

ProCarManuals.com

NOTE:There are steps that you can take to slow down
an impending overheat condition. If your air conditioner
is on, turn it off. The air conditioning system adds heat to
the engine cooling system and turning off the A/C
removes this heat. You can also turn the Temperature
control to maximum heat, the Mode control to floor, and
the fan control to HI. 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 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 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, see Section 7, Maintenance, of this
manual. Follow the warnings under the Cooling
System Pressure Cap paragraph.

JUMP-STARTING PROCEDURES
WARNING!
•Take care to avoid the radiator cooling fan whenever the
hood is raised. It can start anytime the ignition switch is on.
You can be hurt by the fan.
•Do not attempt to push or tow your vehicle to get it started.
Vehicles equipped with an automatic transmission cannot
be started this way. Unburned fuel could enter the catalytic
converter and once the engine has started, ignite and
damage the converter and vehicle. If the vehicle has a
discharged battery, booster cables may be used to obtain a
start from another vehicle. This type of start can be danger-
ous if done improperly, so follow this procedure carefully.
•Battery fluid is a corrosive acid solution; do not allow
battery fluid to contact eyes, skin, or clothing. Don’t lean
over battery when attaching clamps or allow the clamps to
touch each other. If acid splashes in eyes or on skin, flush
contaminated area immediately with large quantities of
water.
•A battery generates hydrogen gas, which is flammable and
explosive. Keep flame or spark away from the vent holes.
•Do not use a booster battery or any other booster source
with an output that exceeds 12 volts.
•The battery in this vehicle has a vent hose that should not
be disconnected and should only be replaced with a battery
of the same type (vented).
NOTE:The battery is stored under an access cover in
the trunk. Remote battery terminals are located in the
engine compartment for jump-starting.
1. Wear eye protection and remove any metal jewelry
such as watchbands or bracelets that might make an
inadvertent electrical contact.
2. When boost is provided by a battery in another
vehicle, park that vehicle within booster cable reach, but
do not allow the vehicles to touch one another.
WARNING!
Do not permit vehicles to touch each other as this
could establish a ground connection and personal
injury could result.
3. Set the parking brake, place the automatic transmis-
sion in PARK, and turn the ignition switch to the OFF (or
LOCK) position on both vehicles.
4. Turn off the heater, radio, and all unnecessary electri-
cal loads.

Cooling System
WARNING!
•When working near the radiator cooling fan, dis-
connect the fan motor lead or turn the ignition
switch to the OFF position. The fan is temperature
controlled and can start at any time the ignition
switch is in the ON position.
•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, don’t 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 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 to
drain from the coolant recovery bottle. DO NOT RE-
MOVE THE COOLANT PRESSURE CAP WHEN THE
COOLING SYSTEM IS HOT.
