2018 CHRYSLER PACIFICA automatic transmission

4. The STOP/START system will reset itself back to an ONcondition every time the ignition is turned off and back
on.
Automatic Shutdown
This vehicle is equipped with an automatic shutdown
feature. If the vehicle is left in READY mode (vehicle
running) with the gear selector in PARK for one hour after
the driver exits, this feature will automatically turn the
vehicle off. Notifications have been added into this feature
to raise awareness of the timed event:
• In the interior of the vehicle, the instrument cluster will
display “Ready To Drive”, and will be accompanied by
three audible chimes while exiting. These interior warn-
ings will occur regardless of whether the key fob re-
mains in the vehicle or is removed.
• For the exterior of the vehicle, the horn will sound three
times if the fob is removed from the vehicle and the
vehicle is in the “READY” mode.
Please consider this feature when intentionally running the
vehicle for extended periods of time over one hour. To
restart the vehicle, follow the normal vehicle starting
process. NOTE:
If the vehicle is left in the ACC or RUN (engine not
running) position and the transmission is in PARK, the
system will automatically time out (shut down) after an
initial 30 minutes of inactivity, followed by the additional
amount of time for power accessory delay selected in the
radio settings menu. Once the vehicle times out, it will
switch to the OFF position.
To Manually Turn On The Stop/Start System
After turning off the STOP/START system, push the
STOP/START OFF switch again (located on the instrument
panel). The light on the switch will turn off.
System Malfunction
If there is a malfunction in the STOP/START system, the
system will not shut down the engine. A “SERVICE STOP/
START SYSTEM” message will appear in the instrument
cluster display and the Stop/Start telltale will remain
yellow. Refer to “Instrument Cluster Display” in “Getting
To Know Your Instrument Panel” for further information.
If the “SERVICE STOP/START SYSTEM” message appears
in the instrument cluster display, have the system checked
by your authorized dealer.

PARKSENSE REAR PARK ASSIST — IF EQUIPPED
The ParkSense Rear Park Assist system provides visual and
audible indications of the distance between the rear fascia
and a detected obstacle when backing up, e.g. during a
parking maneuver. If your vehicle is equipped with an
Automatic Transmission, the vehicle brakes may be auto-
matically applied and released when performing a reverse
parking maneuver if the system detects a possible collision
with an obstacle.
NOTE:
•The driver can override the automatic braking function
by pressing the gas pedal, turning ParkSense off via
ParkSense switch, or changing the gear while the auto-
matic brakes are being applied.

STARTING AND OPERATING 351

WARNING!
•Drivers must be careful when backing up even when
using ParkSense. Always check carefully behind
your vehicle, look behind you, and be sure to check
for pedestrians, animals, other vehicles, obstructions,
and blind spots before backing up. You are respon-
sible for safety and must continue to pay attention to
your surroundings. Failure to do so can result in
serious injury or death.
• Before using ParkSense, it is strongly recommended
that the ball mount and hitch ball assembly is
disconnected from the vehicle when the vehicle is
not used for towing. Failure to do so can result in
injury or damage to vehicles or obstacles because the
hitch ball will be much closer to the obstacle than the
rear fascia when the loudspeaker sounds the con-
tinuous tone. Also, the sensors could detect the ball
mount and hitch ball assembly, depending on its size
and shape, giving a false indication that an obstacle
is behind the vehicle.
CAUTION!
•ParkSense is only a parking aid and it is unable to
recognize every obstacle, including small obstacles.
Parking curbs might be temporarily detected or not
detected at all. Obstacles located above or below the
sensors will not be detected when they are in close
proximity.
• The vehicle must be driven slowly when using
ParkSense in order to be able to stop in time when an
obstacle is detected. It is recommended that the
driver looks over his/her shoulder when using
ParkSense.
PARKSENSE FRONT AND REAR PARK ASSIST —
IF EQUIPPED
The ParkSense Park Assist system provides visual and
audible indications of the distance between the rear and/or
front fascia and a detected obstacle when backing up or
moving forward, e.g. during a parking maneuver. If your
vehicle is equipped with an Automatic Transmission, the
vehicle brakes may be automatically applied and released
when performing a reverse parking maneuver if the sys-
tem detects a possible collision with an obstacle.

Towing Tips
Before setting out on a trip, practice turning, stopping, and
backing up the trailer in an area located away from heavy
traffic.
Automatic Transmission
Select the DRIVE range when towing. The transmission
controls include a drive strategy to avoid frequent shifting
when towing. For increased engine braking on steep down-
hill grades, select the LOW range.
Speed Control — If Equipped
•Do not use on hilly terrain or with heavy loads.
• When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
• Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission overheat-
ing, take the following actions:
City Driving
•In city traffic — while stopped, place the transmission in
NEUTRAL, but do not increase engine idle speed.
Highway Driving
• Reduce speed.
• Temporarily turn off air conditioning.

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.
