overheat CHRYSLER PACIFICA 2019 User Guide

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 you use the SET (-)button to decelerate, if the
powertrain braking power does not slow the vehicle
sufficiently to reach the set speed, the brake system will
automatically slow the vehicle.
• The ACC system decelerates the vehicle to a full stop
when following a target vehicle. If an ACC host vehicle
follows a target vehicle to a standstill, after two seconds
the driver will either have to push the RES (resume)
button, or apply the accelerator pedal to reengage the
ACC to the existing set speed.
• The ACC system maintains set speed when driving up
hill and down hill. 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 up hill and down hill, 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.

REFUELING IN EMERGENCY
The funnel for the Cap-Less Fuel System is located with the
spare tire (if equipped) or in the upper storage bin. If your
vehicle is out of fuel and an auxiliary fuel can is needed,
insert the funnel into the filler neck and proceed to fill the
vehicle.
For more information on the Cap-Less Fuel System refer to
“Refueling The Vehicle” in “Starting And Operating” in
this manual.
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.
• In city traffic — while stopped, place the transmission in
NEUTRAL, but do not increase engine idle speed.
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

IN CASE OF EMERGENCY 499

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” 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!
• 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 transmission failure during pro-
longed 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 overheating and failure. It
can also damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear (no transmis-
sion shifting occurring).
502 IN CASE OF EMERGENCY

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.

530 SERVICING AND MAINTENANCE

•Mix a minimum solution of 50% OAT engine coolant
that meets the requirements of FCA 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 (anti-
freeze) 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 prop-
erly. 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 autho-
rized dealer.
•
Mixing engine coolant (antifreeze) types is not recom-
mended and can result in cooling system damage. If HOAT and OAT coolant are mixed in an emergency, have a
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
(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.

Tires — General Information
Tire Pressure
Proper tire inflation pressure is essential to the safe and
satisfactory operation of your vehicle. Four primary areas
are affected by improper tire pressure:
•Safety and Vehicle Stability
• Economy
• Tread Wear
• Ride Comfort
Safety
WARNING!
• Improperly inflated tires are dangerous and can
cause collisions.
• Underinflation increases tire flexing and can result
in overheating and tire failure.
• Overinflation reduces a tire’s ability to cushion
shock. Objects on the road and chuckholes can cause
damage that result in tire failure.
(Continued)
WARNING! (Continued)
•Overinflated or underinflated tires can affect vehicle
handling and can fail suddenly, resulting in loss of
vehicle control.
• Unequal tire pressures can cause steering problems.
You could lose control of your vehicle.
• Unequal tire pressures from one side of the vehicle
to the other can cause the vehicle to drift to the right
or left.
• Always drive with each tire inflated to the recom-
mended cold tire inflation pressure.
Both under-inflation and over-inflation affect the stability
of the vehicle and can produce a feeling of sluggish
response or over responsiveness in the steering.
NOTE:
• Unequal tire pressures from side to side may cause
erratic and unpredictable steering response.
• Unequal tire pressure from side to side may cause the
vehicle to drift left or right.
548 SERVICING AND MAINTENANCE

MMT In Gasoline
Methylcyclopentadienyl Manganese Tricarbonyl (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. Gaso-
line 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
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.
(Continued)
CAUTION! (Continued)
•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.
