ECU RAM PROMASTER 2022 Owner's Manual

110STARTING AND OPERATING
RIM SIZE
This is the rim size that is appropriate for the tire
size listed.
INFLATION PRESSURE
This is the cold tire inflation pressure for your
vehicle for all loading conditions up to full Gross
Axle Weight Rating (GAWR).
CURB WEIGHT
The curb weight of a vehicle is defined as the total
weight of the vehicle with all fluids, including
vehicle fuel, at full capacity conditions, and with
no occupants or cargo loaded into the vehicle. The
front and rear curb weight values are determined
by weighing your vehicle on a commercial scale
before any occupants or cargo are added.
OVERLOADING
The load carrying components (axle, springs,
tires, wheels, etc.) of your vehicle will provide
satisfactory service as long as you do not exceed
the Gross Vehicle Weight Rating (GVWR) and the
front and rear Gross Axle Weight Rating (GAWR).
The best way to figure out the total weight of your
vehicle is to weigh it when it is fully loaded and
ready for operation. Weigh it on a commercial scale
to ensure that it is not over the GVWR. Figure out the weight on the front and rear axle of
the vehicle separately. It is important that you
distribute the load evenly over the front and rear
axles.
Overloading can cause potential safety hazards
and shorten useful service life. Heavier axles or
suspension components do not necessarily
increase the vehicle's GVWR.
LOADING
To load your vehicle properly, first figure out its
empty weight, axle-by-axle and side-by-side. Store
heavier items down low and be sure you distribute
their weight as evenly as possible. Stow all loose
items securely before driving. If weighing the
loaded vehicle shows that you have exceeded
either Gross Axle Weight Rating (GAWR), but the
total load is within the specified Gross Vehicle
Weight Rating (GVWR), you must redistribute the
weight. Improper weight distribution can have an
adverse effect on the way your vehicle steers and
handles and the way the brakes operate.
NOTE:Refer to the Vehicle Certification Label affixed to
the rear of the driver's door for your vehicle's GVWR
and GAWRs.
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 Ú
page 109.
Gross Combination Weight Rating (GCWR)
The GCWR is the total allowable weight of your
vehicle and trailer when weighed in combination.

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.

Proper tire inflation pressures are essential to the
safe and satisfactory operation of your vehicle.

Check the trailer tires for proper tire inflation
pressures before trailer usage.
Check for signs of tire wear or visible tire
damage before towing a trailer.
Replacing tires with a higher load carrying
capacity will not increase the vehicle's GVWR
and GAWR limits.
For further information Ú page 225.
Towing Requirements — Trailer Brakes
Do not interconnect the hydraulic brake system
or vacuum system of your vehicle with that of
the trailer. This could cause inadequate braking
and possible personal injury.
An electronically actuated trailer brake
controller is required when towing a trailer with
electronically actuated brakes. When towing a
trailer equipped with a hydraulic surge actuated
brake system, an electronic brake controller is
not required.
Trailer brakes are recommended for trailers
over 1,000 lb (453 kg) and may be required for
any trailer, for example trailers in excess of
2,000 lb (907 kg). Trailer brake requirements
vary by local law, consult local legal require -
ments where the trailer is to be towed for trailer
brake requirements.
WARNING!
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, transmis -
sion, steering, suspension, 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.
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 :
GVWR
GTW
GAWR
Tongue weight rating for the trailer hitch
utilized.
WARNING!
WARNING!

Do not connect trailer brakes to your vehicle's
hydraulic brake lines. It can overload your brake
system and cause it to fail. You might not have
brakes when you need them and could have an
accident.

22_VF_OM_EN_USC_t.book Page 114

STARTING AND OPERATING117
RECREATIONAL TOWING
Recreational towing is allowed ONLY if the
front wheels are OFF the ground. This may be
accomplished using a tow dolly or vehicle trailer.
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. Firmly apply the parking brake. Place the transmission in PARK.
4. Properly secure the front wheels to the dolly, following the dolly manufacturer's instructions.
5. Release the parking brake.
DRIVING TIPS
DRIVING ON SLIPPERY SURFACES
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.
Traction
When driving on wet or slushy roads, it is possible
for a wedge of water to build up between the tire
and road surface. This is hydroplaning and may
cause partial or complete loss of vehicle control
and stopping ability. To reduce this possibility, the
following precautions should be observed:
Slow down during rainstorms or when the roads
are slushy.
Slow down if the road has standing water or
puddles.
Replace the tires when tread wear indicators
first become visible.
Keep tires properly inflated.
Maintain sufficient distance between your
vehicle and the vehicle in front of you to avoid a
collision in a sudden stop.CAUTION!
DO NOT flat tow this vehicle. Damage to the
drivetrain will result. If this vehicle requires
towing, make sure the drive wheels are OFF
the ground.

Towing this vehicle in violation of the above
requirements can cause severe transmission
damage. Damage from improper towing is not
covered under the New Vehicle Limited Warranty.

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 carefully whenever there is likely to be
poor traction (ice, snow, wet, mud, loose sand, etc.).

OCCUPANT RESTRAINT SYSTEMS
Some of the most important safety features in your
vehicle are the restraint systems:
OCCUPANT RESTRAINT SYSTEMS
F
EATURES
Seat Belt Systems
Supplemental Restraint Systems (SRS) Air Bags
Child Restraints
Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on others.
If you are not sure, ask an authorized dealer.
IMPORTANT SAFETY PRECAUTIONS
Please pay close attention to the information in
this section. It tells you how to use your restraint
system properly, to keep you and your passengers
as safe as possible.
Here are some simple steps you can take to
minimize the risk of harm from a deploying air bag:

1. Children 12 years old and under should always ride buckled up in the rear seat of a
vehicle with a rear seat.

2. A child who is not big enough to wear the vehicle seat belt properly must be secured in
the appropriate child restraint or belt-positioning booster seat in a rear seating
position Ú
page 168.
3. If a child from 2 to 12 years old (not in a rear-facing child restraint) must ride in the
front passenger seat, move the seat as far
back as possible and use the proper child
restraint Ú page 168.
4. Never allow children to slide the shoulder belt behind them or under their arm.
5. You should read the instructions provided with your child restraint to make sure that you are
using it properly.
6. All occupants should always wear their lap and shoulder belts properly.
7. The driver and front passenger seats should be moved back as far as practical to allow the
front air bags room to inflate.
8. Do not lean against the door or window. If your vehicle has side air bags, and deployment
occurs, the side air bags will inflate forcefully
into the space between occupants and the
door and occupants could be injured.
9. If the air bag system in this vehicle needs to be modified to accommodate a disabled person,
see Úpage 253 for customer service contact
information.
SEAT BELT SYSTEMS
Buckle up even though you are an excellent driver,
even on short trips. Someone on the road may be
a poor driver and could cause a collision that
includes you. This can happen far away from home
or on your own street.
Research has shown that seat belts save lives, and
they can reduce the seriousness of injuries in a
collision. Some of the worst injuries happen when
people are thrown from the vehicle. Seat belts
reduce the possibility of ejection and the risk of
injury caused by striking the inside of the vehicle.
Everyone in a motor vehicle should be belted at all
times.
WARNING!
Never place a rear-facing child restraint in
front of an air bag. A deploying passenger
front air bag can cause death or serious injury
to a child 12 years or younger, including a
child in a rear-facing child restraint.
Never install a rear-facing child restraint in the
front seat of a vehicle. Only use a rear-facing
child restraint in the rear seat. If the vehicle
does not have a rear seat, do not transport a
rear-facing child restraint in that vehicle.

Enhanced Seat Belt Use Reminder System
(BeltAlert)
Driver And Passenger BeltAlert — If Equipped BeltAlert is a feature intended to remind
the driver and outboard front seat
passenger (if equipped with outboard
front passenger seat BeltAlert) to buckle
their seat belts. The BeltAlert feature is active
whenever the ignition switch is in the AVV (START)
or MAR (ACC/ON/RUN) position.
Initial Indication
If the driver is unbuckled when the ignition switch
is first in the AVV (START) or MAR (ACC/ON/RUN)
position, a chime will signal for a few seconds.
If the driver or outboard front seat passenger
(if equipped with outboard front passenger seat
BeltAlert) is unbuckled when the ignition switch is
first in the AVV (START) or MAR (ACC/ON/RUN)
position the Seat Belt Reminder Light will turn on
and remain on until both outboard front seat belts
are buckled. The outboard front passenger seat
BeltAlert is not active when an outboard front
passenger seat is unoccupied.
BeltAlert Warning Sequence
The BeltAlert warning sequence is activated when
the vehicle is moving above a specified vehicle
speed range and the driver or outboard front seat
passenger is unbuckled (if equipped with outboard
front passenger seat BeltAlert) (the outboard front passenger seat BeltAlert is not active when the
outboard front passenger seat is unoccupied).
The BeltAlert warning sequence starts by blinking
the Seat Belt Reminder Light and sounding an
intermittent chime. Once the BeltAlert warning
sequence has completed, the Seat Belt Reminder
Light will remain on until the seat belts are
buckled. The BeltAlert warning sequence may
repeat based on vehicle speed until the driver
and occupied outboard front seat passenger seat
belts are buckled. The driver should instruct all
occupants to buckle their seat belts.
Change Of Status
If the driver or outboard front seat passenger
(if equipped with outboard front passenger seat
BeltAlert) unbuckles their seat belt while the
vehicle is traveling, the BeltAlert warning sequence
will begin until the seat belts are buckled again.
The outboard front passenger seat BeltAlert is not
active when the outboard front passenger seat is
unoccupied. BeltAlert may be triggered when an
animal or other items are placed on the outboard
front passenger seat or when the seat is folded flat
(if equipped). It is recommended that pets be
restrained in the rear seat (if equipped) in pet
harnesses or pet carriers that are secured by seat
belts, and cargo is properly stowed.
BeltAlert can be activated or deactivated by
an authorized dealer. FCA US LLC does not
recommend deactivating BeltAlert.
NOTE:If BeltAlert has been deactivated and the driver or
outboard front seat passenger (if equipped with
outboard front passenger seat BeltAlert) is
unbuckled the Seat Belt Reminder Light will turn
on and remain on until the driver and outboard
front seat passenger seat belts are buckled.
Lap/Shoulder Belts
All seating positions in your vehicle are equipped
with lap/shoulder belts.
The seat belt webbing retractor will lock only during
very sudden stops or collisions. This feature allows
the shoulder part of the seat belt to move freely
with you under normal conditions. However, in a
collision the seat belt will lock and reduce your risk
of striking the inside of the vehicle or being thrown
out of the vehicle.
WARNING!
Relying on the air bags alone could lead to
more severe injuries in a collision. The air
bags work with your seat belt to restrain you
properly. In some collisions, the air bags won’t
deploy at all. Always wear your seat belt even
though you have air bags.

Seat Belts And Pregnant Women

Seat Belts And Pregnant Women

Seat belts must be worn by all occupants including
pregnant women: the risk of injury in the event of
an accident is reduced for the mother and the
unborn child if they are wearing a seat belt.
Position the lap belt snug and low below the
abdomen and across the strong bones of the hips.
Place the shoulder belt across the chest and away
from the neck. Never place the shoulder belt
behind the back or under the arm.
Seat Belt Pretensioner
The front seat belt system is equipped with
pretensioning devices that are designed to remove
slack from the seat belt in the event of a collision.
These devices may improve the performance of
the seat belt by removing slack from the seat belt
early in a collision. Pretensioners work for all size
occupants, including those in child restraints.
NOTE:These devices are not a substitute for proper seat
belt placement by the occupant. The seat belt still
must be worn snugly and positioned properly.
The pretensioners are triggered by the Occupant
Restraint Controller (ORC). Like the air bags, the
pretensioners are single use items. A deployed
pretensioner or a deployed air bag must be
replaced immediately.
Energy Management Feature
The front seat belt system is equipped with an
Energy Management feature that may help further
reduce the risk of injury in the event of a collision.
The seat belt system has a retractor assembly that
is designed to release webbing in a controlled
manner.
Switchable Automatic Locking
Retractor (ALR)
The seat belt in the passenger seating position is
equipped with a Switchable Automatic Locking
Retractor (ALR) which is used to secure a child
restraint system Ú page 171. The figure below
illustrates the locking feature for each seating
position.

for a short period of time, typically 30 seconds or
less. The EDR in this vehicle is designed to record
such data as:

How various systems in your vehicle were oper -
ating;
Whether or not the driver and passenger safety
belts were buckled/fastened;
How far (if at all) the driver was depressing the
accelerator and/or brake pedal; and,
How fast the vehicle was traveling.
These data can help provide a better
understanding of the circumstances in which
crashes and injuries occur.
NOTE:EDR data are recorded by your vehicle only if a
non-trivial crash situation occurs; no data are
recorded by the EDR under normal driving condi -
tions and no personal data (e.g., name, gender,
age, and crash location) are recorded. However,
other parties, such as law enforcement, could
combine the EDR data with the type of personally
identifying data routinely acquired during a crash
investigation.
To read data recorded by an EDR, special equipment
is required, and access to the vehicle or the EDR is
needed. In addition to the vehicle manufacturer,
other parties, such as law enforcement, that have
the special equipment, can read the information if
they have access to the vehicle or the EDR.

CHILD RESTRAINTS
Everyone in your vehicle needs to be buckled up at
all times, including babies and children. Every
state in the United States, and every Canadian
province, requires that small children ride in
proper restraint systems. This is the law, and you
can be prosecuted for ignoring it.
Children 12 years or younger should ride properly
buckled up in a rear seat, if available. According to
crash statistics, children are safer when properly
restrained in the rear seats rather than in the front.
There are different sizes and types of restraints for
children from newborn size to the child almost
large enough for an adult safety belt. Always check
the child seat Owner’s Manual to make sure you
have the correct seat for your child. Carefully read
and follow all the instructions and warnings in the
child restraint Owner’s Manual and on all the
labels attached to the child restraint.
Before buying any restraint system, make sure that
it has a label certifying that it meets all applicable
Safety Standards. You should also make sure that
you can install it in the vehicle where you will use it.
NOTE:
For additional information, refer to http://
www.nhtsa.gov/parents-and-caregivers or

Canadian residents should refer to Transport
Canada’s website for additional information:
http://www.tc.gc.ca/en/services/road/
child-car-seat-safety.htmlWARNING!
In a collision, an unrestrained child can become
a projectile inside the vehicle. The force required
to hold even an infant on your lap could become
so great that you could not hold the child, no
matter how strong you are. The child and others
could be badly injured or killed. Any child riding
in your vehicle should be in a proper restraint for
the child’s size.

22_VF_OM_EN_USC_t.book Page 168

170SAFETY
(Continued)
All children whose weight or height is above the
forward-facing limit for the child seat should use a
belt-positioning booster seat until the vehicle’s
seat belts fit properly. If the child cannot sit with
knees bent over the vehicle’s seat cushion while
the child’s back is against the seatback, they
should use a belt-positioning booster seat.
The child and belt-positioning booster seat are
held in the vehicle by the seat belt.
Children Too Large For Booster Seats
Children who are large enough to wear the
shoulder belt comfortably, and whose legs are long
enough to bend over the front of the seat when
their back is against the seatback, should use the
seat belt in a rear seat. Use this simple 5-step test
to decide whether the child can use the vehicle’s
seat belt alone:

1. Can the child sit all the way back against the
back of the vehicle seat?

2. Do the child’s knees bend comfortably over the front of the vehicle seat while the child is
still sitting all the way back?
3. Does the shoulder belt cross the child’s shoulder between the neck and arm? 4. Is the lap part of the belt as low as possible,
touching the child’s thighs and not the
stomach?

5. Can the child stay seated like this for the whole trip?

If the answer to any of these questions was “no,”
then the child still needs to use a booster seat in
this vehicle. If the child is using the lap/shoulder
belt, check seat belt fit periodically and make sure
the seat belt buckle is latched. A child’s squirming
or slouching can move the belt out of position.
If the shoulder belt contacts the face or neck, move
the child closer to the center of the vehicle, or use
a booster seat to position the seat belt on the child
correctly.
WARNING!
Improper installation can lead to failure of an
infant or child restraint. It could come loose in
a collision. The child could be badly injured or
killed. Follow the child restraint manufac -
turer’s directions exactly when installing an
infant or child restraint.
After a child restraint is installed in the
vehicle, do not move the vehicle seat forward
or rearward because it can loosen the child
restraint attachments. Remove the child
restraint before adjusting the vehicle seat
position. When the vehicle seat has been
adjusted, reinstall the child restraint.
When your child restraint is not in use, secure
it in the vehicle with the seat belt or LATCH
anchorages, or remove it from the vehicle.
Do not leave it loose in the vehicle. In a
sudden stop or accident, it could strike the
occupants or seatbacks and cause serious
personal injury.
WARNING!
WARNING!
Never allow a child to put the shoulder belt
under an arm or behind their back. In a crash,
the shoulder belt will not protect a child properly,
which may result in serious injury or death.
A child must always wear both the lap and
shoulder portions of the seat belt correctly.

Installing Child Restraints In Commercial
Vehicles

This commercial vehicle is not designed for use as
a family vehicle and is not intended for carrying
children in the front passenger seat(s). Never install
rear-facing child restraints in this vehicle. Although
the seat belt can be locked to secure a child
restraint, there are no tether anchorages to
complete the proper installation of a forward-facing
child restraint. If you must carry a child in a
forward-facing child restraint, the passenger seat
should be moved to the full rearward position and
the child must be in a proper restraint system based
on its age, size and weight. Follow the instructions
below to secure the child restraint using the
seat belt.

Installing Child Restraints Using The
Vehicle Seat Belt
Child restraint systems are designed to be secured
in vehicle seats by lap belts or the lap belt portion
of a lap/shoulder belt.

The seat belts in the passenger seating positions are
equipped with a Switchable Automatic Locking
Retractor (ALR). This seat belt is designed to keep
the lap portion of the seat belt tight around the child
restraint so that it is not necessary to use a locking
clip. The ALR retractor can be “switched” into a
locked mode by pulling all of the webbing out of the
retractor and then letting the webbing retract back
into the retractor. If it is locked, the ALR will make a
clicking noise while the webbing is pulled back into
the retractor. See the “Automatic Locking Mode”
description in “Switchable Automatic Locking
Retractors (ALR)”

passenger air bag. In a collision, a passenger air
bag may deploy causing severe injury or death to
infants riding in rear-facing infant restraints.
WARNING!
Improper installation or failure to properly
secure a child restraint can lead to failure of
