2008 CHRYSLER 300 C engine overheat

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.
JACKING AND TIRE CHANGING
WARNING!
•Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off
the road to avoid the danger of being hit when
operating the jack or changing the wheel.
•Getting under a jacked-up vehicle is dangerous.
The vehicle could slip off the jack and fall on you.
You could be crushed. Never get any part of your
body under a vehicle that is on a jack. Never start
or run the engine while the vehicle is on a jack. If
you need to get under a raised vehicle, take it to a
service center where it can be raised on a lift.
•The jack is designed to use as a tool for changing
tires only. The jack should not be used to lift the
vehicle for service purposes. The vehicle should
be jacked on a firm level surface only. Avoid ice or
slippery areas.
394 WHAT TO DO IN EMERGENCIES

CAUTION!
•When “rocking” a stuck vehicle by moving be-
tween “First” and R (Reverse), do not spin the
wheels faster than 15 mph (24 km/h), or drivetrain
damage may result.
•Racing the engine or spinning the wheels too fast
may lead to transmission overheating and failure.
It can also damage the tires. Do not spin the
wheels above 35 mph (55 km/h).
WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause tire dam-
age or failure. A tire could explode and injure some-
one. Do not spin your vehicle’s wheels faster than 35
mph (55 km/h) when you are stuck, and don’t let
anyone near a spinning wheel, no matter what the
speed.
TOWING A DISABLED VEHICLE
WITHOUT THE IGNITION KEY
Special care must be taken when the vehicle is towed
with the ignition in the LOCK position. The only ap-
proved method of towing without the ignition key is
with a flat bed truck. Proper towing equipment is neces-
sary to prevent damage to the vehicle.
408 WHAT TO DO IN EMERGENCIES

Catalytic Converter
The catalytic converter requires the use of unleaded fuel
only. Leaded gasoline will destroy the effectiveness of the
catalyst as an emission control device.
Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is im-
portant to keep the engine properly tuned to assure
proper catalyst operation and prevent possible catalyst
damage.CAUTION!
Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In
the event of engine malfunction, particularly involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Contin-
ued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and the
vehicle.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.

WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your exhaust
system. Do not park or operate your vehicle in areas
where your exhaust system can contact anything that
can burn.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may indicate severe
and abnormal catalyst overheating. If this should occur,
safely bring the vehicle to a complete stop, shut the
engine off, and allow the vehicle to cool. Thereafter,
obtain service, including a tune-up to manufacturer’s
specifications immediately.To minimize the possibility of catalyst 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 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
idling or malfunctioning operating conditions.
Maintenance-Free Battery
The top of the MAINTENANCE-FREE battery is perma-
nently sealed. You will never have to add water, nor is
periodic maintenance required.
NOTE:The battery is stored under an access cover in
the trunk. Remote battery terminals are located in the
engine compartment for jump-starting.
428 MAINTAINING YOUR VEHICLE

•Use only high purity water such as distilled or deion-
ized water when mixing the water/engine coolant
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 coolant types will decrease the life of the
engine coolant and will require more frequent coolant
changes.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of
coolant, and to insure that coolant 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.
WARNING!
•The warning words “DO NOT OPEN HOT” on
the cooling system pressure cap are a safety pre-
caution. Never add coolant 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 scald-
ing 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.
