overheating CHRYSLER PACIFICA 2018 Owners Manual

Automatic Temperature Control (ATC) — If
Equipped
Automatic Operation
1. Push the AUTO button on the faceplate, or the AUTObutton on the touchscreen on the Automatic Tempera-
ture Control (ATC) Panel.
2. Next, adjust the temperature you would like the system to maintain by adjusting the driver and passenger
temperature control buttons. Once the desired tempera-
ture is displayed, the system will achieve and automati-
cally maintain that comfort level.
3. When the system is set up for your comfort level, it is not necessary to change the settings. You will experience
the greatest efficiency by simply allowing the system to
function automatically.
NOTE:
• It is not necessary to move the temperature settings for
cold or hot vehicles. The system automatically adjusts
the temperature, mode, and blower speed to provide
comfort as quickly as possible.
• The temperature can be displayed in U.S. or Metric units
by selecting the US/Metric customer-programmable fea- ture. Refer to the “Uconnect Settings” in “Multimedia”
for further information.
To provide you with maximum comfort in the Automatic
mode during cold start-ups, the blower fan will remain on
low until the engine warms up. The blower will increase in
speed and transition into Auto mode.
Manual Operation Override
This system offers a full complement of manual override
features. The AUTO symbol in the front ATC display will
be turned off when the system is being used in the manual
mode.
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) is recommended. Refer
to “Fluids And Lubricants” in “Technical Specifications”
for proper coolant selection.
130 GETTING TO KNOW YOUR VEHICLE

2. Press and hold the desired HomeLink button until theindicator light begins to flash after 20 seconds. Do not
release the button.
3. Without releasing the button, proceed with “Program- ming A Non-Rolling Code” step 2 and follow all remain-
ing steps.
Canadian/Gate Operator Programming
For programming transmitters in Canada/United States
that require the transmitter signals to “time-out” after
several seconds of transmission.
Canadian radio frequency laws require transmitter signals
to time-out (or quit) after several seconds of transmission –
which may not be long enough for HomeLink to pick up
the signal during programming. Similar to this Canadian
law, some U.S. gate operators are designed to time-out in
the same manner.
It may be helpful to unplug the device during the cycling
process to prevent possible overheating of the garage door
or gate motor.
1. Cycle the ignition to the ON/RUN position. 2. Place the hand-held transmitter 1 to 3 inches (3 to 8 cm)
away from the HomeLink button you wish to program
while keeping the HomeLink indicator light in view.
3. Continue to press and hold the HomeLink button, while you press and release (“cycle”) your hand-held trans-
mitter every two seconds until HomeLink has success-
fully accepted the frequency signal. The indicator light
will flash slowly and then rapidly when fully trained.
4. Watch for the HomeLink indicator to change flash rates. When it changes, it is programmed. It may take up to 30
seconds or longer in rare cases. The garage door may
open and close while you are programming.
5. Press and hold the programmed HomeLink button and observe the indicator light.
NOTE: •If the indicator light stays on constantly, programming
is complete and the garage door/device should acti-
vate when the HomeLink button is pressed.
• To program the two remaining HomeLink buttons,
repeat each step for each remaining button. DO NOT
erase the channels.
158 GETTING TO KNOW YOUR VEHICLE

CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can cause
severe transmission damage.
Refer to “Recreational Towing” in “Starting And Op-
erating” and “Towing A Disabled Vehicle” in “In Case
Of Emergency” for further information.
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and downshifts,
and the best fuel economy. The transmission automatically
upshifts through all forward gears. The DRIVE position
provides optimum driving characteristics under all normal
operating conditions.
If the transmission temperature exceeds normal operating
limits, the transmission controller may modify the trans-
mission shift schedule, reduce engine torque, and/or ex-
pand the range of torque converter clutch engagement.
This is done to prevent transmission damage due to
overheating.If the transmission becomes extremely hot, the
Transmis-
sion Temperature Warning Light will illuminate, a warn-
ing message will appear in the instrument cluster, and the
transmission may operate differently until the transmission
cools down.
During cold temperatures, transmission operation may be
modified depending on engine and transmission tempera-
ture as well as vehicle speed. This feature improves warm
up time of the engine and transmission to achieve maxi-
mum efficiency. Engagement of the torque converter
clutch, and shifts into 8th or 9th gear, are inhibited until the
transmission fluid is warm (refer to the “Note” under
“Torque Converter Clutch” in this section). Normal opera-
tion will resume once the transmission temperature has
risen to a suitable level.
LOW (L)
Use this range for engine braking when descending very
steep grades. In this range, the transmission will downshift
for increased engine braking. To access the LOW position,
push down on the gear selector and rotate it fully clock-
wise.

STARTING AND OPERATING 323

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
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.

IN CASE OF EMERGENCY 479

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
(Continued)
CAUTION! (Continued)
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).
TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled
vehicle using a commercial towing service.
482 IN CASE OF EMERGENCY

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!
•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,
(Continued)
WARNING! (Continued)
do not open the hood until the radiator has had time
to cool. Never open a cooling system pressure cap
when the radiator or coolant bottle is hot.
• Keep hands, tools, clothing, and jewelry away from
the radiator cooling fan when the hood is raised. The
fan starts automatically and may start at any time,
whether the engine is running or not.
• When working near the radiator cooling fan, discon-
nect the fan motor lead or turn the ignition to the
OFF mode. The fan is temperature controlled and can
start at any time the ignition is in the ON mode.
Engine Coolant Checks
Check the engine coolant (antifreeze) protection every 12
months (before the onset of freezing weather, where appli-
cable). If the engine coolant (antifreeze) is dirty, the system
should be drained, flushed, and refilled with fresh OAT
coolant (conforming to MS.90032) by an authorized dealer.
Check the front of the A/C condenser for any accumula-
tion of bugs, leaves, etc. If dirty, clean by gently spraying
water from a garden hose vertically down the face of the
condenser.
510 SERVICING AND MAINTENANCE

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.
