2018 CHRYSLER PACIFICA ECU

The entire vehicle should first be weighed on a commercial
scale to insure that the GVWR has not been exceeded. The
weight on the front and rear of the vehicle should then be
determined separately to be sure that the load is properly
distributed over the front and rear axle. Weighing the
vehicle may show that the GAWR of either the front or rear
axles has been exceeded but the total load is within the
specified GVWR. If so, weight must be shifted from front to
rear or rear to front as appropriate until the specified
weight limitations are met. Store the heavier items down
low and be sure that the weight is distributed equally. Stow
all loose items securely before driving.
Improper weight distributions can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate.
CAUTION!
Do not load your vehicle any heavier than the GVWR
or the maximum front and rear GAWR. If you do, parts
on your vehicle can break, or it can change the way
your vehicle handles. This could cause you to lose
control. Also overloading can shorten the life of your
vehicle.
TRAILER TOWING
In this section you will find safety tips and information on
limits to the type of towing you can reasonably do with
your vehicle. Before towing a trailer, carefully review this
information to tow your load as efficiently and safely as
possible.
To maintain the New Vehicle Limited Warranty coverage,
follow the requirements and recommendations in this
manual concerning vehicles used for trailer towing.
Common Towing Definitions
The following trailer towing related definitions will assist
you in understanding the following information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, cargo and tongue weight.
The total load must be limited so that you do not exceed
the GVWR. Refer to “Vehicle Loading/Vehicle Certification
Label” in “Starting And Operating” for further informa-
tion.

Maintenance” for the proper maintenance intervals. When
towing a trailer, never exceed the GAWR or GCWR ratings.
WARNING!
Improper towing can lead to a collision. Follow these
guidelines to make your trailer towing as safe as
possible:
•Make certain that the load is secured in the trailer
and will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have a collision.
• When hauling cargo or towing a trailer, do not
overload your vehicle or trailer. Overloading can
cause a loss of control, poor performance or damage
to brakes, axle, engine, transmission, steering, sus-
pension, chassis structure or tires.
• Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
hook retainers of the vehicle hitch. Cross the chains
under the trailer tongue and allow enough slack for
turning corners.
(Continued)
WARNING! (Continued)
•Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on the
tow vehicle. Put the tow vehicle transmission in
PARK. For four-wheel drive vehicles, make sure the
transfer case is not in NEUTRAL. Always, block or
chock the trailer wheels.
• GCWR must not be exceeded.
• Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR
4. Tongue weight rating for the trailer hitch utilized.
Towing Requirements — Tires
• Do not attempt to tow a trailer while using a compact
spare tire.
• Do not drive more than 50 mph (80 km/h) when towing
while using a full size spare tire.
414 STARTING AND OPERATING

Recreational towing is allowed ONLY if the front wheels
areOFF the ground. This may be accomplished using a tow
dolly (front wheels off the ground) or vehicle trailer (all
four wheels off the ground). If using a tow dolly, follow this
procedure:
1. Properly secure the dolly to the tow vehicle, following the dolly manufacturer’s instructions.
2. Drive the front wheels onto the tow dolly.
3. Apply the park brake.
4. Place the transmission in PARK.
5. Turn the ignition OFF.
6. Properly secure the front wheels to the dolly, following the dolly manufacturer’s instructions.
7. Turn the ignition to the ON/RUN mode, but do not start the vehicle.
8. Press and hold the brake pedal.
9. Release the park brake.
10. Turn the ignition OFF.
11. Release the brake pedal.DRIVING TIPS
Driving On Slippery Surfaces
Information in this section will aid in safe controlled
launches in adverse conditions.
Acceleration
Rapid acceleration on snow covered, wet, or other slippery
surfaces may cause the driving wheels to pull erratically to
the right or left. This phenomenon occurs when there is a
difference in the surface traction under the front (driving)
wheels.
WARNING!
Rapid acceleration on slippery surfaces is dangerous.
Unequal traction can cause sudden pulling of the front
wheels. You could lose control of the vehicle and
possibly have a collision. Accelerate slowly and care-
fully whenever there is likely to be poor traction (ice,
snow, wet, mud, loose sand, etc.).

Fuse Location
The fuses are grouped into a controller located in the
engine compartment.
Underhood Fuses
The Power Distribution Center is located in the engine
compartment near the battery. This center contains car-
tridge fuses, mini-fuses, micro-fuses, circuit breakers and
relays. A label that identifies each component is printed on
the inside of the cover.
Before any procedure is done on the PDC, make sure
engine is turned off.
Remove the cover by unlatching the two locks located at
each side of the PDC cover, avoid the usage of screw
drivers or any other tool to remove the cover, since they
may apply excessive force and result in a broken/damaged
part.After service is done, secure the cover with its two locks.

CAUTION!
Do not attempt to raise the vehicle by jacking on
locations other than those indicated.
3. Place the wrench on the jack screw and turn to the right until the jack head is properly engaged in the described
location. Do not raise the vehicle until you are sure the
jack is securely engaged.
4. Raise the vehicle by turning the jack screw to the right, using the swivel wrench. Raise the vehicle only until the
tire just clears the surface and enough clearance is obtained to install the compact spare tire. Minimum tire
lift provides maximum stability.
WARNING!
Raising the vehicle higher than necessary can make the
vehicle less stable. It could slip off the jack and hurt
someone near it. Raise the vehicle only enough to
remove the tire.
5. Remove the wheel lug nuts, for vehicles with wheel covers, remove the cover from the wheel by hand. Do
not pry the wheel cover off. Then pull the wheel off the
hub.
6. Install the inflatable spare on the vehicle, located in the rear cargo area of the vehicle.
WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the wheel nuts fully until the vehicle has
been lowered. Failure to follow this warning may
result in serious injury.

CAUTION!
Be sure to mount the inflatable spare tire with the
valve stem facing outward. The vehicle could be dam-
aged if the inflatable spare tire is mounted incorrectly.
NOTE: Do not install the wheel cover on the inflatable
spare tire. 7. Leave the vehicle on the jack and start inflating the
inflatable spare after the tire has been mounted to the
vehicle. Secure the wheel to the hub by tightening the
nuts with wrench. After inflation, once the vehicle is
lowered you will have a second opportunity to “torque”
the lug nuts.
8. Inflate the tire to the prescribed pressure 60 psi (4.2 Bar) using the Portable Air Compressor or Tire Service Kit if
equipped. Refer to “Portable Air Compressor” in this
section for usage procedure if equipped. Refer to “Tire
Service Kit For Inflating Tire” in this section for usage
procedure if equipped.
Inflate the tire to the prescribed pressure 60 psi (4.2 Bar)
using the Portable Air Compressor. Refer to “Portable Air
Compressor” in this section for usage procedure.
9. Lower the vehicle once the inflatable Spare has reached its pressure and the compressor-hose has been removed
from the tire valve.
