2019 CHRYSLER PACIFICA overheat

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 339

NOTE:Any chassis/suspension or tire size modifications
to the vehicle will effect the performance of the Adaptive
Cruise Control and Forward Collision Warning System.
Activating Adaptive Cruise Control (ACC)
You can only engage ACC if the vehicle speed is above
0 mph (0 km/h).
The minimum set speed for the ACC system is 20 mph
(32 km/h).
When the system is turned on and in the READY state, the
instrument cluster displays “ACC Ready.”
When the system is OFF, the instrument cluster display
“Adaptive Cruise Control (ACC) Off.”
NOTE: You cannot engage ACC under the following con-
ditions:
• When you apply the brakes.
• When the parking brake is applied.
• When the automatic transmission is in PARK, REVERSE
or NEUTRAL.
• When the vehicle speed is outside of the speed range.
• When the brakes are overheated. •
When the driver door is open at low speed.
• When the driver seat belt is unbuckled at low speed.
To Activate/Deactivate
Push and release the Adaptive Cruise Control (ACC)
on/off button. The ACC menu in the instrument cluster
displays “ACC Ready.”
To turn the system off, push and release the Adaptive
Cruise Control (ACC) on/off button again. At this time, the
system will turn off and the instrument cluster display will
show “Adaptive Cruise Control (ACC) Off.”

STARTING AND OPERATING 351

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

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.
