2022 CHRYSLER 300 engine overheat

STARTING AND OPERATING97
The transmission will automatically downshift to
FIRST gear when coming to a stop. After a stop,
the driver should manually upshift (+) the trans -
mission as the vehicle is accelerated.
You can start out, from a stop, in FIRST or
SECOND gear. Tapping (+) at a stop will allow
starting in SECOND gear. Starting out in
SECOND gear can be helpful in snowy or icy
conditions.
If a requested downshift would cause the
engine to over-speed, that shift will not occur.
The system will ignore attempts to upshift at too
low of a vehicle speed.
Holding the (-) paddle pressed will downshift the
transmission to the lowest gear possible at the
current speed.
Transmission shifting will be more noticeable
when AutoStick is enabled.
The system may revert to automatic shift mode
if a fault or overheat condition is detected.
To disengage AutoStick mode, press and hold the
(+) shift paddle until "D" or "S" is once again
indicated in the instrument cluster. Shifting out of
SPORT mode will also disable AutoStick. You can
shift in or out of AutoStick mode at any time
without taking your foot off the accelerator pedal.
SPORT MODE — IF EQUIPPED

SPORT Mode Button

If your vehicle is equipped with SPORT mode, this mode
is a configuration set up for typical enthusiast driving.
The engine, transmission and steering systems are all
set to their SPORT settings. SPORT mode will provide
improved throttle response and modified shifting for an
enhanced driving experience, as well the greatest
amount of steering feel. This mode may be activated
and deactivated by pushing the SPORT button on the
instrument panel switch bank.

FUEL SAVER TECHNOLOGY 5.7L ONLY —
IF EQUIPPED
This feature offers improved fuel economy by
shutting off four of the engine's eight cylinders
during light load and cruise conditions. The system
is automatic with no driver inputs or additional
driving skills required.
NOTE:This system may take some time to return to full
functionality after a battery disconnect.
POWER STEERING
The Electric Power Steering system provides
increased vehicle response and ease of
maneuverability in tight spaces. The system
adapts to different driving conditions. If the electric
steering system experiences a fault that prevents
it from providing assist, you will still have the ability
to steer the vehicle manually.
WARNING!
Do not downshift for additional engine braking
on a slippery surface. The drive wheels could
lose their grip and the vehicle could skid,
causing a collision or personal injury.
WARNING!
Continued operation with reduced assist could
pose a safety risk to yourself and others. Service
should be obtained as soon as possible.

104STARTING AND OPERATING
Metric Speed (km/h)
Pushing the SET (+) , or SET (-) button once will
result in a 1 km/h speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 km/h.

If the button is continually pushed, the set speed
will continue to adjust in 10 km/h increments
until the button is released. The new set speed is
reflected in the instrument cluster display.

NOTE:When you override and push the SET (+) button or
SET (-) buttons, the new set speed will be the
current speed of the vehicle.
When ACC Is Active:
NOTE:
When you use the SET (-) button to decelerate, if
the engine’s braking power does not slow the
vehicle sufficiently to reach the set speed, the
brake system will automatically slow the
vehicle.
The ACC will bring the vehicle to a complete stop
while following a vehicle in front and hold the
vehicle for two seconds in the stop position. If
the vehicle in front does not start moving within
two seconds, the ACC system will display a
message that the system will release the brakes
and that the brakes must be applied manually.
An audible chime will sound when the brakes
are released.
The ACC system maintains set speed when
driving uphill and downhill. However, a slight
speed change on moderate hills is normal. In
addition, downshifting may occur while climbing
uphill or descending downhill. This is normal
operation and necessary to maintain set speed.
When driving uphill and downhill, the ACC
system will cancel if the braking temperature
exceeds normal range (overheated).
Setting The Following Distance In ACC
The specified following distance for ACC can be set
by varying the distance setting between four bars
(longest), three bars (long), two bars (medium) and
one bar (short). Using this distance setting and the
vehicle speed, ACC calculates and sets the
distance to the vehicle ahead. This distance
setting displays in the instrument cluster display.
Distance Settings

To increase the distance setting, push the
Distance Setting Increase button and release.
Each time the button is pushed, the distance
setting increases by one bar (longer).
To decrease the distance setting, push the
Distance Setting Decrease button and release.
Each time the button is pushed, the distance
setting decreases by one bar (shorter). 1 — Longest Distance Setting (Four Bars)
2 — Medium Distance Setting (Two Bars)
3 — Long Distance Setting (Three Bars)
4 — Short Distance Setting (One Bar)

(Continued)
NOTE:In certain cold conditions, ice may prevent the fuel
door from opening. If this occurs, lightly push on
the fuel door to break the ice buildup and
re-release the fuel door using the inside release
button. Do not pry on the door.
Refueling Funnel

Emergency Gas Can Refueling
Most gas cans will not open the flapper doors. A
funnel is provided to allow emergency refueling
with a gas can.
See below steps for refueling:

1. Retrieve funnel from the spare tire storage area.

2. Insert funnel into same filler pipe opening as the fuel nozzle.
Inserting Funnel

3. Ensure funnel is inserted fully to hold flapper doors open.
4. Pour fuel into funnel opening.
5. Remove funnel from filler pipe, clean off prior to putting back in the spare tire storage area.
IF YOUR ENGINE OVERHEATS
If the vehicle is overheating, it will need to be
serviced by an authorized dealer.
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 trans -
mission in NEUTRAL, but do not increase the
engine idle speed while preventing vehicle
motion with the brakes.
CAUTION!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
WARNING!
Never have any smoking materials lit in or
near the vehicle when the fuel door is open or
the tank is being filled.
Never add fuel when the engine is running.
This is in violation of most state and federal
fire regulations and may cause the Malfunc -
tion Indicator Light to turn on.
A fire may result if fuel is pumped into a
portable container that is inside of a vehicle.
You could be burned. Always place fuel
containers on the ground while filling.
WARNING!

22_LX_OM_EN_USC_t.book Page 204

IN CASE OF EMERGENCY205
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.
MANUAL PARK RELEASE
To move the vehicle in cases where the
transmission will not shift out of PARK (such as a
depleted battery), a Manual Park Release is
available.
Follow these steps to use the Manual Park
Release:

1. Firmly apply the parking brake.

2. Remove the console storage bin to access the
Manual Park Release lever.

Manual Park Release Cover

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.
WARNING!
Always secure your vehicle by fully applying the
parking brake before activating the Manual Park
Release. In addition, you should be seated in the
driver's seat with your foot firmly on the brake
pedal when activating the Manual Park Release.
Activating the Manual Park Release will allow
your vehicle to roll away if it is not secured by the
parking brake, or by proper connection to a tow
vehicle. Activating the Manual Park Release on
an unsecured vehicle could lead to serious
injury or death for those in or around the vehicle.

(Continued)
NOTE:
For vehicles with automatic transmission: Shifts
between DRIVE and REVERSE can only be
achieved at wheel speeds of 5 mph (8 km/h) or
less. Whenever the transmission remains in
NEUTRAL for more than two seconds, you must
press the brake pedal to engage DRIVE or
REVERSE.
Push the ESC OFF button to place the Electronic
Stability Control (ESC) system in “Partial OFF”
mode, before rocking the vehicle Ú page 147.
Once the vehicle has been freed, push the ESC
OFF button again to restore “ESC On” mode.
CAUTION!
Racing the engine or spinning the wheels may
lead to transmission overheating and failure.
Allow the engine to idle with the transmission in
NEUTRAL for at least one minute after every five
rocking-motion cycles. This will minimize
overheating and reduce the risk of clutch or
transmission failure during prolonged efforts to
free a stuck vehicle.
WARNING!
Fast spinning tires can be dangerous. Forces
generated by excessive wheel speeds may
cause damage, or even failure, of the axle and
tires. A tire could explode and injure someone.
Do not spin your vehicle's wheels faster than
30 mph (48 km/h) or for longer than 30
seconds continuously without stopping when
you are stuck and do not let anyone near a
spinning wheel, no matter what the speed.
CAUTION!
Racing the engine or spinning the wheels may
lead to transmission overheating and failure.
Allow the engine to idle with the transmission
in NEUTRAL for at least one minute after every
five rocking-motion cycles. This will minimize
overheating and reduce the risk of transmis -
sion failure during prolonged efforts to free a
stuck vehicle.
When “rocking” a stuck vehicle by shifting
between DRIVE and REVERSE, do not spin the
wheels faster than 15 mph (24 km/h), or
drivetrain damage may result.

Revving the engine or spinning the wheels
too fast may lead to transmission over -
heating and failure. It can also damage the
tires. Do not spin the wheels above 30 mph
(48 km/h) while in gear (no transmission
shifting occurring).

CAUTION!

SERVICING AND MAINTENANCE223
(Continued) Under normal operating conditions, the catalytic
converter will not require maintenance. However, it
is important to keep the engine properly tuned to
ensure proper catalyst operation and prevent
possible catalyst damage.
NOTE:Intentional tampering with emission control
systems can result in civil penalties being
assessed against you. In unusual situations involving grossly
malfunctioning engine operation, a scorching odor
may suggest severe and abnormal catalyst
overheating. If this occurs, stop the vehicle, turn off
the engine and allow it to cool. Service, including a
tune-up to manufacturer's specifications, should
be obtained immediately.
To minimize the possibility of catalytic converter
damage:
Do not shut off the engine or interrupt the igni-
tion 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 diag
-
nostic testing, or for prolonged periods during
very rough idle or malfunctioning operating
conditions.
NOTE:Your vehicle’s exhaust system may be equipped
with an Electronic Exhaust Valve (EEV) system, if
the exhaust system is replaced with aftermarket
products a Malfunction Indicator Lamp (MIL) will
illuminate.
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you uncon -
scious and can eventually poison you. To
avoid breathing CO Ú page 191.

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.

CAUTION!
The catalytic converter requires the use of
unleaded fuel only. Leaded gasoline will
destroy the effectiveness of the catalyst as an
emissions control device and may seriously
reduce engine performance and cause
serious damage to the engine.
Damage to the catalytic converter can result if
your vehicle is not kept in proper operating
condition. In the event of engine malfunction,
particularly involving engine misfire or other
apparent loss of performance, have your
vehicle serviced promptly. Continued opera -
tion of your vehicle with a severe malfunction
could cause the converter to overheat,
resulting in possible damage to the converter
and vehicle.
CAUTION!

SERVICING AND MAINTENANCE225
Adding Coolant

Your vehicle has been built with an improved engine
coolant (OAT coolant conforming to MS.90032) that
allows extended maintenance intervals. This engine
coolant (antifreeze) can be used up to 10 years or
150,000 miles (240,000 km) before replacement.
To prevent reducing this extended maintenance
period, it is important that you use the same engine
coolant (OAT coolant conforming to MS.90032)
throughout the life of your vehicle.

Please review these recommendations for using
Organic Additive Technology (OAT) engine coolant
that meets the requirements of the manufacturer
Material Standard MS.90032. When adding
engine coolant:
We recommend using Mopar® Antifreeze/
Coolant 10 Year/150,000 Mile (240,000 km)
Formula OAT that meets the requirements of the
manufacturer Material Standard MS.90032.
Mix a minimum solution of 50% OAT engine
coolant that meets the requirements of the
manufacturer Material Standard MS.90032
and distilled water. Use higher concentrations
(not to exceed 70%) if temperatures below
−34°F (−37°C) are anticipated. Please contact
an authorized dealer for assistance.
Use only high purity water such as distilled or
deionized 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.
NOTE:
It is the owner's responsibility to maintain the
proper level of protection against freezing
according to the temperatures occurring in the
area where the vehicle is operated.
Some vehicles require special tools to add
coolant properly. Failure to fill these systems
properly could lead to severe internal engine
damage. If any coolant is needed to be added to
the system, please contact a local authorized
dealer.
Mixing engine coolant types is not recom -
mended and can result in cooling system
damage. If HOAT and OAT coolant are mixed in
an emergency, have an authorized dealer drain,
flush, and refill with OAT coolant (conforming to
MS.90032) as soon as possible.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of
engine coolant (antifreeze), and to ensure that
engine coolant will return to the radiator from the
coolant expansion bottle/recovery tank if
equipped. The cap should be inspected and cleaned if there
is any accumulation of foreign material on the
sealing surfaces.
Disposal Of Used Coolant
Used ethylene glycol-based 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 animals or children, do not store
ethylene glycol-based coolant in open containers
or allow it to remain in puddles on the ground,
clean up any ground spills immediately. If ingested
by a child or pet, seek emergency assistance
immediately.
WARNING!
Do not open a hot engine cooling system.
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
engine damage may result.

METHYLCYCLOPENTADIENYL
M
ANGANESE TRICARBONYL (MMT) IN
G
ASOLINE
MMT is a manganese-containing metallic additive
that is blended into some gasoline to increase
octane. Gasoline blended with MMT provides no
performance advantage beyond gasoline of the
same octane number without MMT. Gasoline
blended with MMT reduces spark plug life and
reduces emissions system performance in some
vehicles. The manufacturer recommends that
gasoline without MMT be used in your vehicle. The
MMT content of gasoline may not be indicated on
the gasoline pump; therefore, you should ask your
gasoline retailer whether the gasoline contains
MMT. MMT is prohibited in Federal and California
reformulated gasoline.
FUEL SYSTEM CAUTIONS
NOTE:Intentional tampering with the emissions control
system can result in civil penalties being assessed
against you.
CAUTION!
Follow these guidelines to maintain your
vehicle’s performance:
The use of leaded gasoline is prohibited by
Federal law. Using leaded gasoline can impair
engine performance and damage the emis -
sions control system.
An out-of-tune engine or certain fuel or ignition
malfunctions can cause the catalytic
converter to overheat. If you notice a pungent
burning odor or some light smoke, your engine
may be out of tune or malfunctioning and may
require immediate service. Contact an autho -
rized dealer for service assistance.
The use of fuel additives, which are now being
sold as octane enhancers, is not recom -
mended. Most of these products contain high
concentrations of methanol. Fuel system
damage or vehicle performance problems
resulting from the use of such fuels or addi -
tives is not the responsibility of the manufac-
turer and may void or not be covered under
the New Vehicle Limited Warranty.
