2020 Ram ProMaster City load capacity

GETTING TO KNOW YOUR VEHICLE 73
(Continued)
Distribute cargo weight evenly on the roof rack crossbars.
The roof rack does not increase the total load carrying
capacity of the vehicle. Be sure the total load of cargo inside
the vehicle plus that on the external rack does not exceed the
maximum vehicle load capacity.
To move the crossbars, loosen the attachments, located at the
upper edge of each crossbar, approximately eight turns
using the anti-theft wrench provided with the Mopar cross-
bars. Then, move the crossbar to the desired position,
keeping the crossbars parallel to the rack frame. Once the
crossbar is in the desired position, re-tighten the with the
wrench to lock the crossbar into position.
NOTE:
• To help control wind noise when the crossbars are not in use, place the front and rear crossbars approximately
24 inches (61 cm) apart. Optimal noise reduction can then
be achieved by adjusting the front crossbar forward or aft
using increments of 1 inch (2.5 cm). • If (or any metallic object) is placed over the satellite radio
antenna (if equipped), you may experience interruption of
satellite radio reception. For improved satellite radio
reception, avoid placing the rear crossbar over the satellite
radio antenna.
WARNING!
Cargo must be securely tied down before driving your
vehicle. Improperly secured loads can fly off the vehicle,
particularly at high speeds, resulting in personal injury
or property damage. Follow the roof rack cautions when
carrying cargo on your roof rack.
CAUTION!
• To prevent damage to the roof of your vehicle, DO NOT carry any loads on the roof rack without the crossbars
deployed. The load should be secured and placed on
top of the crossbars, not directly on the roof. If it is
necessary to place the load on the roof, place a blanket
or other protective layer between the load and the roof
surface.

(Continued)
• To avoid damage to the roof rack and vehicle, do notexceed the maximum roof rack load capacity of 150 lb
(68 kg). Always distribute heavy loads as evenly as
possible and secure the load appropriately.
• Load should always be secured to cross bars first, with tie down loops used as additional securing points if
needed. Tie loops are intended as supplementary tie
down points only. Do not use ratcheting mechanisms
with the tie loops. Check the straps and thumb wheels
frequently to be sure that the load remains securely
attached. CAUTION!
(Continued)• Long loads that extend over the windshield, such as
wood panels or surfboards, or loads with large frontal
area should be secured to both the front and rear of the
vehicle.
• Travel at reduced speeds and turn corners carefully when carrying large or heavy loads on the roof rack.
Wind forces, due to natural causes or nearby truck
traffic, can add sudden upward lift to a load. This is
especially true on large flat loads and may result in
damage to the cargo or your vehicle. CAUTION!

Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle. This
includes driver, passengers, and cargo. The total load must
be limited so that you do not exceed the GVWR.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles evenly.
Make sure that you do not exceed either front or rear GAWR.
Tire Size
The tire size on the Vehicle Certification Label represents the
actual tire size on your vehicle. Replacement tires must be
equal to the load capacity of this tire size.
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 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 GVWR and the front and rear
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.
WARNING!
Because the front wheels steer the vehicle, it is important
that you do not exceed the maximum front or rear
GAWR. A dangerous driving condition can result if
either rating is exceeded. You could lose control of the
vehicle and have a collision.5

STARTING AND OPERATING 185
Gross Combination Weight Rating (GCWR)
The GCWR is the total allowable weight of your vehicle and
trailer when weighed in combination.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the weight of all
cargo, consumables and equipment (permanent or tempo-
rary) loaded in or on the trailer in its "loaded and ready for
operation" condition.
The recommended way to measure GTW is to put your fully
loaded trailer on a vehicle scale. The entire weight of the
trailer must be supported by the scale.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles evenly.
Make sure that you do not exceed either front or rear GAWR.
Refer to “Vehicle Loading/Vehicle Certification Label” in
this chapter for further information. Tongue Weight (TW)
The tongue weight is the downward force exerted on the
hitch ball by the trailer. You must consider this as part of the
load on your vehicle.
Trailer Frontal Area
The frontal area is the maximum height multiplied by the
maximum width of the front of a trailer.
Trailer Sway Control
The Trailer Sway Control can be a mechanical telescoping
link that can be installed between the hitch receiver and the
trailer tongue that typically provides adjustable friction asso
-
ciated with the telescoping motion to dampen any unwanted
trailer swaying motions while traveling.WARNING!
It is important that you do not exceed the maximum front
or rear GAWR. A dangerous driving condition can result
if either rating is exceeded. You could lose control of the
vehicle and have a collision.

Towing Requirements — Tires
• Do not attempt to tow a trailer while using a compact sparetire.
• 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. Refer to “Tires” in
“Servicing And Maintenance” for proper tire inflation
procedures.
• 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. Refer to “Tires” in “Servicing And Main -
tenance” for the proper inspection procedure.
• When replacing tires, refer to “Tires” in “Servicing And Maintenance” for the proper tire replacement procedures.
Replacing tires with a higher load carrying capacity will
not increase the vehicle's GVWR and GAWR limits. 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 actu -
ated 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 lbs (453 kg) and required for trailers in excess of 2,000 lbs (907 kg).

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.
• Towing any trailer will increase your stopping distance. When towing, you should allow for addi -
tional space between your vehicle and the vehicle in
front of you. Failure to do so could result in an accident.

Towing Requirements — Trailer Lights And Wiring
Whenever you pull a trailer, regardless of the trailer size,
stoplights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may include a four- and seven-pin
wiring harness. Use a factory approved trailer harness and
connector.
NOTE:
Do not cut or splice wiring into the vehicle’s wiring harness.
The electrical connections are all complete to the vehicle but
you must mate the harness to a trailer connector. Refer to the
following illustrations.NOTE:
• Disconnect trailer wiring connector from the vehicle
before launching a boat (or any other device plugged into
vehicle’s electrical connect) into water.
• Be sure to reconnect once clear from water area.
Four-Pin Connector
CAUTION!
If the trailer weighs more than 1,000 lbs (453 kg) loaded,
it should have its own brakes and they should be of
adequate capacity. Failure to do this could lead to
accelerated brake lining wear, higher brake pedal effort,
and longer stopping distances.
