Cleaning The ParkSense Rear Park Assist System
Clean the ParkSense sensors with water, car wash soap and
a soft cloth. Do not use rough or hard cloths. In washing
stations, clean sensors quickly while keeping the vapor jet/
high pressure washing nozzles at least 4 inches (10 cm) from
the sensors. Do not scratch or poke the sensors. Otherwise,
you could damage the sensors.
ParkSense Rear Park Assist System Usage
Precautions
NOTE:
• Ensure that the outer surface and the underside of the rearbumper is clean and clear of snow, ice, mud, dirt or other
obstruction to keep the ParkSense Rear Park Assist system
operating properly.
• Jackhammers, large trucks, and other vibrations could affect the performance of the ParkSense system.
• Clean the ParkSense sensors regularly, taking care not to scratch or damage them. The sensors must not be covered
with ice, snow, slush, mud, dirt or debris. Failure to do so
can result in the system not working properly. The ParkSense system might not detect an obstacle behind the
fascia/bumper, or it could provide a false indication that
an obstacle is behind the fascia/bumper.
• Objects such as bicycle carriers, etc., must not be placed within 12 inches (30 cm) from the rear fascia/bumper
while driving the vehicle. Failure to do so can result in the
system misinterpreting a close object as a sensor problem,
causing a failure indication to be displayed in the instru -
ment cluster display.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 responsible for
safety and must continue to pay attention to your
surroundings. Failure to do so can result in serious
injury or death.

STARTING AND OPERATING 179
If it’s necessary to keep the ball mount and hitch ball
assembly mounted for a long period, it is possible to filter out
the ball mount and hitch ball assembly presence in sensor
field of view. The filtering operation must be performed only
by an authorized dealer.
PARKVIEW REAR BACK UP CAMERA
Your vehicle is equipped with the ParkView Rear Back Up
Camera that allows you to see an on-screen image of the rear
surroundings of your vehicle whenever the gear selector is
put into REVERSE. The image will be displayed on the
touchscreen display along with a caution note to “check
entire surroundings” across the top of the screen. After five
seconds this note will disappear. The ParkView camera is
located on the rear of the vehicle above the rear license plate.

The Rear Back Up Camera can also be activated when the
vehicle is not in REVERSE through the Uconnect System. Refer
to “Uconnect Settings” in “Multimedia” for further information.

NOTE:
If one of the rear cargo doors is not completely closed, the
Back Up Camera cannot provide an accurate image of the
area behind the vehicle. A dedicated message will appear on
the Uconnect display indicating the camera is not in the
correct position.
• Before using ParkSense, it is strongly recommended
that the ball mount and hitch ball assembly is discon -
nected 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 continuous 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 Park -
Sense 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.

180 STARTING AND OPERATING
The Camera Delay setting can be set to on/off in the rear
camera settings menu. When the vehicle is shifted out of
REVERSE and the Camera Delay is turned off, the rear
camera mode is exited and the navigation or audio screen
appears on display again.
When the transmission is shifted out of REVERSE, and
Camera Delay is activated in the menu screen, the camera
image will continue to be displayed for up to 10 seconds,
unless the speed of the vehicle is greater than 8 mph (13 km/h), the transmission is in PARK, or the ignition is placed in
the OFF position.
When displayed, static grid lines will illustrate the width of
the vehicle and will show separate zones that will help
indicate the distance to the rear of the vehicle. The following
table shows the approximate distances for each zone:
NOTE:
If snow, ice, mud, or any foreign substance builds up on the
camera lens, clean the lens, rinse with water, and dry with a
soft cloth. Do not cover the lens.
Zone
Distance To The Rear Of The
Vehicle
Red 0 - 1 ft (0 - 30 cm)
Yellow 1 ft - 3 ft (30 cm - 1 m)
Green 3 ft or greater (1 m or greater)WARNING!
Drivers must be careful when backing up even when
using the ParkView Rear Back Up Camera. Always check
carefully behind your vehicle, and be sure to check for
pedestrians, animals, other vehicles, obstructions, or
blind spots before backing up. You are responsible for
the safety of your surroundings and must continue to
pay attention while backing up. Failure to do so can
result in serious injury or death.
CAUTION!
• To avoid vehicle damage, ParkView should only be used as a parking aid. The ParkView camera is unable
to view every obstacle or object in your drive path.
• To avoid vehicle damage, the vehicle must be driven slowly when using ParkView to be able to stop in time
when an obstacle is seen. It is recommended that the
driver look frequently over his/her shoulder when
using ParkView.

REFUELING THE VEHICLE
The gas cap is located behind the fuel filler door on the left
side of the vehicle. If the gas cap is lost or damaged, be sure
the replacement cap is for use with this vehicle.
1. Open the fuel filler door.
2. Remove the fuel cap by rotating it counterclockwise.Fuel Filler Cap NOTE:
The driver's side sliding door cannot be opened while the
fuel door is open. This feature operates only when the sliding
door is in a closed position prior to opening the fuel door.
3. Fully insert the gasoline nozzle into the filler pipe.
4. Fill the vehicle with fuel.
NOTE:
When the fuel nozzle “clicks” or shuts off, the fuel tank is
full.
5. Remove gasoline nozzle, reinstall fuel cap and close fuel
filler door.
WARNING!
• Never have any smoking materials lit in or near the vehicle when the gas cap is removed or the tank is
being filled.
• Never add fuel when the engine is running. This is in violation of most state and federal fire regulations and
may cause the “Malfunction Indicator Light (MIL)”to
turn on.

182 STARTING AND OPERATING
NOTE:
• Tighten the fuel filler cap until you hear a “clicking”sound. This is an indication that the fuel filler cap is prop -
erly tightened.
• If the gas cap is not tightened properly, the MIL may come on. Be sure the gas cap is tightened every time the vehicle
is refueled.
VEHICLE LOADING
As required by National Highway Traffic Safety Administra -
tion regulations, your vehicle has a certification label affixed
to the driver's side door or B-Pillar.
If seats are removed for carrying cargo, do not exceed the
specified GVWR and GAWR.
Vehicle Certification Label
Your vehicle has a Vehicle Certification Label affixed to the
drivers side B-Pillar or the rear of the driver’s door.
The label contains the following information:
• Name of manufacturer
• Month and year of manufacture
• Gross Vehicle Weight Rating (GVWR)
• Gross Axle Weight Rating (GAWR) front
• Gross Axle Weight Rating (GAWR) rear
• Vehicle Identification Number (VIN)
• Type of vehicle
• Month, Day, and Hour of manufacture (MDH)
The bar code allows a computer scanner to read the VIN.
• A fire may result if gasoline is pumped into a portable
container that is inside of a vehicle. You could be
burned. Always place gas containers on the ground
while filling.
CAUTION!
• Damage to the fuel system or emissions control system could result from using an improper fuel tank filler
tube cap. A poorly fitting cap could let impurities into
the fuel system and may cause the “Malfunction Indi -
cator Light (MIL)” to turn on, due to fuel vapors
escaping from the system.
• To avoid fuel spillage and overfilling, do not “top off” the fuel tank after filling.

STARTING AND OPERATING 183
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
2020_RAM_PROMASTER_CITY_OM_USA=GUID-7B6A7FCA-79B0-423F-95C5-ED2A949C3D13=1=en=.book Page 183

184 STARTING AND OPERATING
Figure out the weight on the front and rear 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 GAWR, but the total load is within the specified
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
B-Pillar or 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 infor-
mation 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 this chapter for further information.
2020_RAM_PROMASTER_CITY_OM_USA=GUID-7B6A7FCA-79B0-423F-95C5-ED2A949C3D13=1=en=.book Page 184

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.

2020_RAM_PROMASTER_CITY_OM_USA=GUID-7B6A7FCA-79B0-423F-95C5-ED2A949C3D13=1=en=.book Page 185

186 STARTING AND OPERATING
If equipped, the electronic Trailer Sway Control (TSC) recog-
nizes a swaying trailer and automatically applies individual
wheel brakes and/or reduces engine power to attempt to
eliminate the trailer sway.
Weight-Carrying Hitch
A weight-carrying hitch supports the trailer tongue weight,
just as if it were luggage located at a hitch ball or some other
connecting point of the vehicle. These kinds of hitches are the
most popular on the market today and they are commonly
used to tow small and medium sized trailers.
Weight-Distributing Hitch
The weight-distributing hitch works by applying leverage
through spring (load) bars. They are typically used for
heavier loads to distribute trailer tongue weight to the tow
vehicle's front axle and the trailer axle(s). When used in
accordance with the manufacturer's directions, it provides
for a more level ride, offering more consistent steering and
brake control thereby enhancing towing safety. The addition
of a friction/hydraulic sway control also dampens sway caused by traffic and crosswinds and contributes positively
to tow vehicle and trailer stability. Trailer sway control and
a weight distributing (load equalizing) hitch are recom
-
mended for heavier Tongue Weights (TW) and may be
required depending on vehicle and trailer configuration/
loading to comply with Gross Axle Weight Rating (GAWR)
requirements.
WARNING!
• An improperly adjusted Weight Distributing Hitch system may reduce handling, stability, braking perfor -
mance, and could result in a collision.
• Weight Distributing Systems may not be compatible with Surge Brake Couplers. Consult with your hitch
and trailer manufacturer or a reputable Recreational
Vehicle dealer for additional information.
