engine overheat CHRYSLER PACIFICA HYBRID 2019 Owners Manual

Operating Tips
NOTE:Refer to the chart at the end of this section for
suggested control settings for various weather conditions.
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corrosion
protection and to protect against engine overheating. OAT
coolant (conforming to MS.90032) with deionized, or dis-
tilled water for proper corrosion protection is recom-
mended.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is functioning
properly and the proper amount, type, and concentration
of coolant is used. Use of the Air Recirculation mode
during Winter months is not recommended, because it may
cause window fogging.
Vacation/Storage
Before you store your vehicle, or keep it out of service (i.e.,
vacation) for two weeks or more, run the air conditioning
system at idle for about five minutes, in fresh air with the blower setting on high. This will ensure adequate system
lubrication to minimize the possibility of compressor dam-
age when the system is started again.
Window Fogging
Vehicle windows tend to fog on the inside in mild, rainy,
and/or humid weather. To clear the windows, select De-
frost or Mix mode and increase the front blower speed. Do
not use the Recirculation mode without A/C for long
periods, as fogging may occur.
CAUTION!
Failure to follow these cautions can cause damage to
the heating elements:
•
Use care when washing the inside of the rear win-
dow. Do not use abrasive window cleaners on the
interior surface of the window. Use a soft cloth and a
mild washing solution, wiping parallel to the heat-
ing elements. Labels can be peeled off after soaking
with warm water.
• Do not use scrapers, sharp instruments, or abrasive
window cleaners on the interior surface of the win-
dow.
• Keep all objects a safe distance from the window.
122 GETTING TO KNOW YOUR VEHICLE

Vehicles equipped with the Anti-Lock Brake System (ABS)
are also equipped with Electronic Brake Force Distribution
(EBD). In the event of an EBD failure, the Brake Warning
Light will turn on along with the ABS Light. Immediate
repair to the ABS system is required.
Operation of the Brake Warning Light can be checked by
turning the ignition switch from the OFF position to the
ON/RUN position. The light should illuminate for ap-
proximately two seconds. The light should then turn off
unless the parking brake is applied or a brake fault is
detected. If the light does not illuminate, have the light
inspected by an authorized dealer.
The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN position.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake application.
— Battery Charge Warning Light
This warning light illuminates when the 12 volt battery is
not charging properly. If it stays on while the vehicle is
running, there may be a malfunction with the charging
system. Contact an authorized dealer as soon as possible.
This indicates a possible problem with the electrical system
or a related component.
— Engine Coolant Temperature Warning Light
This warning light warns of an overheated engine condi-
tion. If the engine coolant temperature is too high, this
indicator will illuminate and a single chime will sound. If
the temperature reaches the upper limit, a continuous
chime will sound for four minutes or until the engine is
able to cool: whichever comes first.
If the light turns on while driving, safely pull over and stop
the vehicle. If the A/C system is on, turn it off. Also, shift
the transmission into NEUTRAL and idle the vehicle. If the
temperature reading does not return to normal, turn the
engine off immediately and call for service.
Refer to “If Your Engine Overheats” in “In Case Of
Emergency” for further information.
— Electronic Throttle Control (ETC) Warning
Light
This warning light will illuminate to indicate a problem
with the Electronic Throttle Control (ETC) system. If a
problem is detected while the vehicle is running, the light
will either stay on or flash depending on the nature of the
problem. Cycle the ignition when the vehicle is safely and
completely stopped and the transmission is placed in the
PARK position. The light should turn off. If the light

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.
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.
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 temperature gauge reads “H”, pull over and
stop the vehicle. Idle the vehicle with the air condi-
tioner turned off until the pointer drops back into the
normal range. If the pointer remains on the “H”, turn
the vehicle off immediately, and call for service.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or snow, it can
often be moved using a rocking motion. Turn the steering
wheel right and left to clear the area around the front
wheels. Then shift back and forth between DRIVE and
REVERSE while gently pressing the accelerator.
NOTE: 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 half a second, you must press the brake pedal to
engage DRIVE or REVERSE.
Use the least amount of accelerator pedal pressure that will
maintain the rocking motion without spinning the wheels
or holding down the accelerator pedal.
436 IN CASE OF EMERGENCY

NOTE:Push the ESC Off switch to place the Electronic
Stability Control (ESC) system in Partial Offmode, before
rocking the vehicle. Refer to “Electronic Brake Control
System” in “Safety” for further information. Once the
vehicle has been freed, push the ESC Offswitch again to
restore ESC On mode.
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!
•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.
• Spinning the wheels too fast may lead to transmis-
sion overheating 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).
• Allow the engine to idle with the transmission in
NEUTRAL for at least one minute after every five
rocking-motion cycles. This will minimize overheat-
ing and reduce the risk of transmission failure dur-
ing prolonged efforts to free a stuck vehicle.

IN CASE OF EMERGENCY 437

CAUTION!
•The catalytic converter requires the use of unleaded
fuel only. Leaded gasoline will destroy the effective-
ness 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 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
vehicle.
Under normal operating conditions, the catalytic converter
will not require maintenance. However, it is important to
keep the engine properly tuned to assure proper catalyst
operation and prevent possible catalyst damage.
NOTE: Intentional tampering with emissions control sys-
tems 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 interrupt the ignition when the transmission is in
gear and the vehicle is in motion.
• Do not try to start the vehicle by pushing or towing the
vehicle.
• Do not idle the engine with any ignition components
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough idle
or malfunctioning operating conditions.
Cooling System
WARNING!
• Turn vehicle OFF and disconnect the fan motor lead
before working near the radiator cooling fan.

SERVICING AND MAINTENANCE 463

Please note that 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.
NOTE:
•Mixing coolant (antifreeze) types is not recommended
and can result in cooling system damage. If HOAT and
OAT coolant are mixed in an emergency, have a autho-
rized dealer drain, flush, and refill with OAT coolant
(conforming to MS.90032) as soon as possible.
• Low pressure expansion bottles for power electronics
and battery cooling require a special tool for removing
the cap from the expansion bottle. For the battery
coolant bottle, it is important to not add coolant if level
is low. The vehicle should be taken to an authorized
dealer for proper servicing of the battery coolant loop if
this should occur.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of engine
coolant (antifreeze), and to ensure that engine coolant
(antifreeze) will return to the radiator from the coolant
expansion bottle/recovery tank if so equipped. The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
WARNING!
•
Do not open hot engine cooling system. Never add
engine coolant (antifreeze) when the engine is over-
heated. 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 speci-
fied for your vehicle. Personal injury or engine
damage may result.
Disposal Of Used Coolant
Used ethylene glycol-based coolant (antifreeze) is a regu-
lated 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 contain-
ers 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.

SERVICING AND MAINTENANCE 467

Fuel System Cautions
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 perfor-
mance and damage the emissions 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 authorized dealer for service assistance.
• The use of fuel additives, which are now being sold
as octane enhancers, is not recommended. Most of
these products contain high concentrations of metha-
nol. Fuel system damage or vehicle performance
problems resulting from the use of such fuels or
additives is not the responsibility of the manufac-
turer and may void or not be covered under the New
Vehicle Limited Warranty. NOTE:
Intentional tampering with the emissions control
system can result in civil penalties being assessed against
you.Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon mon-
oxide poisoning:
• Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas, which can
kill. Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for an extended period. If the vehicle
is stopped in an open area with the engine running
for more than a short period, adjust the ventilation
system to force fresh, outside air into the vehicle.
• Guard against carbon monoxide with proper main-
tenance. Have the exhaust system inspected every
time the vehicle is raised. Have any abnormal condi-
tions repaired promptly. Until repaired, drive with
all side windows fully open.
