GETTING TO KNOW YOUR INSTRUMENT PANEL 87
If the light continues to flash when the vehicle is running,
immediate service is required and you may experience
reduced performance, an elevated/rough idle, or engine
stall and your vehicle may require towing. The light will
come on when the ignition is placed in the ON/RUN or
MAR/ON/RUN position and remain on briefly as a bulb
check. If the light does not come on during starting, have the
system checked by an authorized dealer.
Engine Coolant Temperature Warning Light This warning light warns of an overheated engine
condition. If the engine coolant temperature is too
high, this indicator will illuminate and a single
chime will sound. If the temperature reaches the upper limit,
a continuous chime will sound for four minutes or until the
engine is able to cool, whichever comes first.
If the light turns on while driving, safely pull over and stop
the vehicle. If the A/C system is on, turn it off. Also, shift the
transmission into NEUTRAL (N) and idle the vehicle. If the
temperature reading does not return to normal, turn the
engine off immediately and call for service.
Refer to “If Your Engine Overheats” in “In Case Of Emer -
gency” for further information. Oil Pressure Warning Light
This warning light will illuminate to indicate low
engine oil pressure. If the light turns on while
driving, stop the vehicle, shut off the engine as soon
as possible, and contact an authorized dealer. A chime will
sound when this light turns on.
Do not operate the vehicle until the cause is corrected. This
light does not indicate how much oil is in the engine. The
engine oil level must be checked under the hood.
Transmission Temperature Warning Light — If Equipped
This warning light will illuminate to warn of a high
transmission fluid temperature. This may occur with
strenuous usage such as trailer towing. If this light
turns on, stop the vehicle and run the engine at idle or
slightly faster, with the transmission in PARK (P) or
NEUTRAL (N), until the light turns off. Once the light turns
off, you may continue to drive normally.
WARNING!
If you continue operating the vehicle when the
Transmission Temperature Warning Light is illuminated
you could cause the fluid to boil over, come in contact
with hot engine or exhaust components and cause a fire.

GETTING TO KNOW YOUR INSTRUMENT PANEL 89
Low Fuel Warning LightWhen the fuel level reaches approximately 2–3 gal
(9–11 L) this light will turn on, and remain on until
fuel is added.
Generic Warning Light The Generic Warning Light will illuminate if any of
the following conditions occur: Engine Oil Pressure
Sensor Failure, External Light Failure, Parking
Sensor Failure, Fuel Cut-Off Fail/Intervention, Generic
Failure on Trailer, or Air Bag telltale recovery.
The telltale will blink in case of an Air Bag Warning Light
Failure. Contact an authorized dealer immediately for
service.
Tire Pressure Monitoring System (TPMS) Warning Light
The warning light switches on and a message is
displayed to indicate that the tire pressure is lower
than the recommended value and/or that slow pres -
sure loss is occurring. In these cases, optimal tire duration
and fuel consumption may not be guaranteed. Should one or more tires be in the condition mentioned
above, the display will show the indications corresponding
to each tire.
Each tire, including the spare (if provided), should be
checked monthly when cold and inflated to the inflation
pressure recommended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label. If your vehicle
has tires of a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those tires.
As an added safety feature, your vehicle has been equipped
with a Tire Pressure Monitoring System (TPMS) that illumi
-
nates a low tire pressure telltale when one or more of your
tires is significantly under-inflated. Accordingly, when the
low tire pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate them to the
CAUTION!
Do not continue driving with one or more flat tires as
handling may be compromised. Stop the vehicle,
avoiding sharp braking and steering. If a tire puncture
occurs, repair immediately using the dedicated tire
repair kit and contact an authorized dealer as soon as
possible.

98 SAFETY
When you are in a severe braking condition involving the
use of the ABS, you will experience some pedal drop as the
vehicle comes to a stop. This is the result of the system
reverting to the base brake system.
Engagement of the ABS may be accompanied by a pulsing
sensation. You may also hear a clicking noise. These occur-
rences are normal and indicate that the system is functioning
properly.
Electronic Brake Control (EBC) System
Your vehicle is equipped with an advanced Electronic Brake
Control (EBC) system that includes the Brake Assist System
(BAS), Traction Control System (TCS), Hill Start Assist
(HSA), Electronic Stability Control (ESC), Electronic Roll
Mitigation (ERM) and Trailer Sway Control (TSC). All
systems work together to enhance vehicle stability and
control in various driving conditions and are commonly
referred to as ESC.
Brake Assist System (BAS)
The Brake Assist System (BAS) is designed to optimize the
vehicle’s braking capability during emergency braking
maneuvers. The system detects an emergency braking situa -
tion by sensing the rate and amount of brake application and
then applies optimum pressure to the brakes. This can help
reduce braking distances. The BAS complements the
Anti-Lock Brake System (ABS). Applying the brakes very
quickly results in the best BAS assistance. To receive the
benefit of the system, you must apply continuous braking
pressure during the stopping sequence, (do not “pump” the
brakes). Do not reduce brake pedal pressure unless braking
is no longer desired. Once the brake pedal is released, the
BAS is deactivated.
• The ABS cannot prevent collisions, including those
resulting from excessive speed in turns, following
another vehicle too closely, or hydroplaning.
• The capabilities of an ABS equipped vehicle must never be exploited in a reckless or dangerous manner
that could jeopardize the user’s safety or the safety of
others.
WARNING! (Continued)

102 SAFETY
Traction Control System (TCS)
The Traction Control System (TCS) monitors the amount of
wheel spin of each of the driven wheels. If wheel spin is
detected, brake pressure is applied to the slipping wheel(s)
and engine power is reduced to provide enhanced accelera-
tion and stability. A feature of the TCS system, Brake Limited
Differential (BLD), functions similar to a limited slip differ -
ential and controls the wheel spin across a driven axle. If one
wheel on a driven axle is spinning faster than the other, the
system will apply the brake of the spinning wheel. This will
allow more engine torque to be applied to the wheel that is
not spinning. This feature remains active even if TCS and
ESC are in the Partial Off mode. Refer to “Electronic Stability
Control (ESC)” in this section for further information. Trailer Sway Control (TSC) — If Equipped
Trailer Sway Control (TSC) uses sensors in the vehicle to
recognize an excessively swaying trailer and will take the
appropriate actions to attempt to stop the sway. The system
may reduce engine power and apply the brake of the appro
-
priate wheel(s) to counteract the sway of the trailer. TSC will
become active automatically once an excessively swaying
trailer is recognized.
NOTE:
TSC cannot stop all trailers from swaying. Always use
caution when towing a trailer and follow the trailer tongue
weight recommendations. Refer to “Trailer Towing” in
“Starting And Operating” for further information.
When TSC is functioning, the “ESC Activation/Malfunction
Indicator Light” will flash, the engine power may be reduced
and you may feel the brakes being applied to individual
wheels to attempt to stop the trailer from swaying. TSC is
disabled when the ESC system is in the “Partial Off” mode.
WARNING!
There may be situations on minor hills with a loaded
vehicle, or while pulling a trailer, when the system will
not activate and slight rolling may occur. This could
cause a collision with another vehicle or object. Always
remember the driver is responsible for braking the
vehicle.
WARNING!
If TSC activates while driving, slow the vehicle down,
stop at the nearest safe location, and adjust the trailer
load to eliminate trailer sway.

168 STARTING AND OPERATING
NEUTRAL (N)
Use this range when the vehicle is standing for prolonged
periods with the engine running. Apply the parking brake
and shift the transmission into PARK if you must exit the
vehicle.DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and downshifts,
and the best fuel economy. The transmission automatically
upshifts through all forward gears. The DRIVE position
provides optimum driving characteristics under all normal
operating conditions.
When frequent transmission shifting occurs (such as when
operating the vehicle under heavy loading conditions, in
hilly terrain, traveling into strong head winds, or while
towing a heavy trailer), use the Electronic Range Select (ERS)
shift control refer to “Electronic Range Select (ERS) Opera
-
tion” in this section for further information to select a lower
gear range. Under these conditions, using a lower gear range
will improve performance and extend transmission life by
reducing excessive shifting and heat buildup.
If the transmission temperature exceeds normal operating
limits, the transmission controller may modify the transmis -
sion shift schedule, reduce engine torque, and/or expand the
range of torque converter clutch engagement. This is done to
prevent transmission damage due to overheating.
WARNING!
Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe practices
that limit your response to changing traffic or road
conditions. You might lose control of the vehicle and
have a collision.
CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can cause
severe transmission damage.
Refer to “Recreational Towing” in “Starting And
Operating” and “Towing A Disabled Vehicle” in “In
Case Of Emergency” for further information.

STARTING AND OPERATING 175
To Resume Speed

To resume a previously set speed, push the RES (+) button and
release. Resume can be used at any speed above 20 mph
(32 km/h) up to the maximum speed of 100 mph (160 km/h).

To Deactivate
A soft tap on the brake pedal, pushing the CAN button, or
normal brake pressure while slowing the vehicle will deacti-
vate the Speed Control without erasing the set speed from
memory.
Pushing the on/off button or turning the ignition switch off
erases the set speed from memory.
PARKSENSE REAR PARK ASSIST — IF EQUIPPED
The ParkSense system provides an audible indication of the
distance between the rear fascia/bumper and a detected
obstacle when backing up (e.g. during a parking maneuver).
Refer to “ParkSense Rear Park Assist System Usage Precau-
tions” in this section for limitations of this system and recom -
mendations.
The ParkSense system is automatically activated when the
transmission is placed into REVERSE. As the distance from
an obstacle behind the vehicle decreases, the audible alert
becomes more frequent.
Interaction With Trailer Towing
The ParkSense system is automatically deactivated when a
trailer equipped by Mopar is hitched to the vehicle. The
system will be automatically activated as soon as the trailer
is removed. If it does not happen, turning the key ignition
switch to OFF and then to ON again would be needed. If a
non-Mopar trailer hitch is mounted, the sensor deactivation
cannot be guaranteed.

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.
