ECU DODGE GRAND CARAVAN 2019 Service Manual

Towing Requirements
To promote proper break-in of your new vehicle drivetrain
components, the following guidelines are recommended.
CAUTION!
•Do not tow a trailer at all during the first 500 miles
(805 km) the new vehicle is driven. The engine, axle
or other parts could be damaged.
• Then, during the first 500 miles (805 km) that a trailer
is towed, do not drive over 50 mph (80 km/h) and do
not make starts at full throttle. This helps the engine
and other parts of the vehicle wear in at the heavier
loads.
Perform the maintenance listed in the “Scheduled Servic-
ing”. Refer to “Scheduled Servicing” in “Servicing And
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.

priate replacement fuse with the same amp rating as
the original fuse. Never replace a fuse with another
fuse of higher amp rating. Never replace a blown
fuse with metal wires or any other material. Do not
place a fuse inside a circuit breaker cavity or vice
versa. Failure to use proper fuses may result in
serious personal injury, fire and/or property damage.
• Before replacing a fuse, make sure that the ignition is
off and that all the other services are switched off
and/or disengaged.
• If the replaced fuse blows again, contact an autho-
rized dealer.

WARNING!(Continued)
•If working on or near a roadway, be extremely
careful of motor traffic.
• To assure that spare tires, flat or inflated, are securely
stowed, spares must be stowed with the valve stem
facing the ground.
CAUTION!
Do not attempt to raise the vehicle by jacking on
locations other than those indicated in the Jacking
Instructions for this vehicle.
NOTE: Refer to the “Compact Spare Tire” section of “Tires
– General Information” in “Servicing And Maintenance”
for information about the compact spare tire, its use, and
operation.
1. Loosen (but do not remove) the wheel lug nuts by turning them to the left one turn while the wheel is still
on the ground.
2. There are two jack engagement locations on each side of the vehicle body. These locations are on the sill flange of
the vehicle body.
Jack Warning Label
304 IN CASE OF EMERGENCY

WARNING!
Being under a jacked-up vehicle is dangerous. The
vehicle could slip off the jack and fall on you. You
could be crushed. Never get any part of your body
under a vehicle that is on a jack. If you need to get
under a raised vehicle, take it to a service center where
it can be raised on a lift.
3. Place the wrench on the jack screw and turn to the right until the jack head is properly engaged in the appropri-
ate 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 by
holding down the wheel and pulling on convenient
features on the cover. Do not pry the wheel cover off.
Then pull the wheel off the hub.
6. Install the compact spare tire. Lightly tighten all the lug nuts until the wheel sits flush onto the hub and there is
no play. The nuts will have to be fully tightened once the
vehicle is lowered. Tightening an improperly seated
wheel under vehicle load can damage the threads, cause
vibration, and undermine safety.
CAUTION!
Be sure to mount the spare tire with the valve stem
facing outward. The vehicle could be damaged if the
spare tire is mounted incorrectly.
308 IN CASE OF EMERGENCY

11. Stow the cable and wheel spacer before driving thevehicle. Reassemble the winch handle extensions to
form a “T” and fit the winch T-handle over the drive
nut. Rotate the nut to the right until the winch mecha-
nism clicks at least three times.
NOTE: Refer to the “Spare Tire Tools” section for instruc-
tions on assembling the T-handle.
12. Stow the jack, jack handle and winch handle tools back in the stowage compartment.
13. Check the compact spare tire pressure as soon as possible. Correct the tire pressure, as required.
Securing The Compact Spare Tire
1. Assemble the winch handle extensions to form aT-handle and fit the winch T-handle over the drive nut.
Rotate the nut to the left until the winch mechanism
stops turning freely. This will allow enough slack in the
cable to allow you to pull the wheel spacer out from
under the vehicle.
WARNING!
A loose compact spare tire/cover assembly, thrown
forward in a collision or hard stop could endanger the
occupants of the vehicle. Always stow the compact
spare tire with the cover assembly in the place pro-
vided.
CAUTION!
The winch mechanism is designed for use with the
winch T-handle only. Use of an air wrench or other
power tools is not recommended and can damage the
winch.
2. Assemble the winch handle extensions to form the spare tire hook, and pull the wheel spacer from under the
vehicle.
3. Turn the compact spare tire so that the valve stem is down, and place the tire into the compact spare tire/
cover assembly. Slide the wheel spacer through the
center of the wheel and compact spare tire/cover assem-
bly, so that the two retainer tabs snap out and engage the
compact spare tire cover on the opposite side.
310 IN CASE OF EMERGENCY

WARNING!
Verify that both retainer tabs of the wheel spacer have
been properly extended through the center of the
wheel and compact spare tire/cover assembly. Failure
to properly engage both retainer tabs could result in
loss of the compact spare tire and cover assembly,
which will cause vehicle damage and may cause loss of
vehicle control and serious personal injury.
CAUTION!
The compact spare tire/cover assembly must be used
when the compact spare tire is stored. Failure to use
this cover could drastically reduce the life of the
compact spare tire.
4. Using the winch T-handle, rotate the drive nut to the right until the compact spare tire/cover assembly is
drawn into place against the underside of the vehicle. 5. Continue to rotate the nut to the right until you hear the
winch mechanism click three times. It cannot be over-
tightened. Check under the vehicle to ensure the com-
pact spare tire/cover assembly is positioned correctly
against the underside of the vehicle.
CAUTION!
The winch mechanism is designed specifically to stow
a compact spare tire only. Do not attempt to use the
winch to stow the full size deflated tire, or any other
full-size tire, as the tire may not be held securely.
Vehicle damage may result.
Road Tire Installation
Vehicles Equipped With Wheel Covers
1. Mount the road tire on the axle.
2. To ease the installation process for steel wheels withwheel covers, install two lug nuts on the mounting
studs which are on each side of the valve stem. Install
the lug nuts with the cone shaped end of the nut toward
the wheel. Lightly tighten the lug nuts.

IN CASE OF EMERGENCY 311

CAUTION!
•Do not use sling type equipment when towing.
Vehicle damage may occur.
• When securing the vehicle to a flatbed truck, do not
attach to front or rear suspension components. Dam-
age to your vehicle may result from improper towing.
• Do not push or tow this vehicle with another vehicle
as damage to the bumper fascia and transmission
may result.
The manufacturer recommends towing your vehicle with
all four wheels OFF the ground using a flatbed. If flatbed
equipment is not available, and the transmission is oper-
able, the vehicle may be flat towed (with all four wheels on
the ground) under the following conditions:
• The transmission must be in NEUTRAL.
• The towing distance must not exceed 15 miles (24 km).
• The towing speed must not exceed 25 mph (40 km/h). If the transmission is not operable, or the vehicle must be
towed faster than 25 mph (40 km/h) or farther than 15
miles (24 km), it must be towed with the front wheels
OFF the ground (using a flatbed truck, or wheel lift
equipment with the front wheels raised).
CAUTION!
Towing faster than 25 mph (40 km/h) or farther than 15
miles (24 km) with front wheels on the ground can
cause severe transmission damage. Damage from im-
proper towing is not covered by the New Vehicle
Limited Warranty.
ENHANCED ACCIDENT RESPONSE SYSTEM
(EARS)
This vehicle is equipped with an Enhanced Accident
Response System.
Please refer to “Occupant Restraint Systems” in “Safety”
for further information on the Enhanced Accident Re-
sponse System (EARS) function.
