Driver and Passenger Front Air Bag Features
The Advanced Front Air Bag system has multistage driver
and front passenger air bags. This system provides output
appropriate to the severity and type of collision as deter-
mined by the Occupant Restraint Controller (ORC), which
may receive information from the front impact sensors (if
equipped) or other system components.
The first stage inflator is triggered immediately during an
impact that requires air bag deployment. A low energy
output is used in less severe collisions. A higher energy
output is used for more severe collisions. This vehicle may be equipped with a driver and/or front
passenger seat belt buckle switch that detects whether the
driver or front passenger seat belt is buckled. The seat belt
buckle switch may adjust the inflation rate of the Advanced
Front Air Bags.
• 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.
WARNING! (Continued)
WARNING!
• No objects should be placed over or near the air bag on the instrument panel or steering wheel because any
such objects could cause harm if the vehicle is in a colli -
sion severe enough to cause the air bag to inflate.
• Do not put anything on or around the air bag covers or attempt to open them manually. You may damage the
air bags and you could be injured because the air bags
may no longer be functional. The protective covers for
the air bag cushions are designed to open only when
the air bags are inflating.
• 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, air
bags won’t deploy at all. Always wear your seat belts
even though you have air bags.

124 SAFETY
Front Air Bag Operation
Front Air Bags are designed to provide additional protection
by supplementing the seat belts. Front air bags are not
expected to reduce the risk of injury in rear, side, or rollover
collisions. The front air bags will not deploy in all frontal
collisions, including some that may produce substantial
vehicle damage — for example, some pole collisions, truck
underrides, and angle offset collisions.
On the other hand, depending on the type and location of
impact, front air bags may deploy in crashes with little
vehicle front-end damage but that produce a severe initial
deceleration.
Because air bag sensors measure vehicle deceleration over
time, vehicle speed and damage by themselves are not good
indicators of whether or not an air bag should have
deployed.
Seat belts are necessary for your protection in all collisions,
and also are needed to help keep you in position, away from
an inflating air bag.When the ORC detects a collision requiring the front air bags,
it signals the inflator units. A large quantity of non-toxic gas
is generated to inflate the front air bags.
The steering wheel hub trim cover and the upper passenger
side of the instrument panel separate and fold out of the way
as the air bags inflate to their full size. The front air bags fully
inflate in less time than it takes to blink your eyes. The front
air bags then quickly deflate while helping to restrain the
driver and front passenger.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees of the driver
and front passenger, and position the front occupants for
improved interaction with the front air bags.
WARNING!
• Do not drill, cut, or tamper with the knee impact bolsters in any way.
• Do not mount any accessories to the knee impact bolsters such as alarm lights, stereos, citizen band
radios, etc.

SAFETY 127
and seated properly, or if items are positioned in the area
where the SABICs inflate. Children are at an even greater
risk of injury from a deploying air bag.
The SABICs may help reduce the risk of partial or complete
ejection of vehicle occupants through side windows in
certain side impact events.Side Impacts
The Side Air Bags are designed to activate in certain side
impacts. The Occupant Restraint Controller (ORC) deter
-
mines whether the deployment of the Side Air Bags in a
particular impact event is appropriate, based on the severity
and type of collision. The side impact sensors aid the ORC in
determining the appropriate response to impact events. The
system is calibrated to deploy the Side Air Bags on the
impact side of the vehicle during impacts that require Side
Air Bag occupant protection. In side impacts, the Side Air
Bags deploy independently; a left side impact deploys the
left Side Air Bags only and a right-side impact deploys the
right Side Air Bags only. Vehicle damage by itself is not a
good indicator of whether or not Side Air Bags should have
deployed.
The Side Air Bags will not deploy in all side collisions,
including some collisions at certain angles, or some side
collisions that do not impact the area of the passenger
compartment. The Side Air Bags may deploy during angled
or offset frontal collisions where the front air bags deploy.
Side Air Bags are a supplement to the seat belt restraint
system. Side Air Bags deploy in less time than it takes to
blink your eyes.
WARNING!
• Do not mount equipment, or stack luggage or other cargo up high enough to block the deployment of the
SABICs. The trim covering above the side windows
where the SABIC and its deployment path are located
should remain free from any obstructions.
• In order for the SABICs to work as intended, do not install any accessory items in your vehicle which could
alter the roof. Do not add an aftermarket sunroof to
your vehicle. Do not add roof racks that require perma -
nent attachments (bolts or screws) for installation on
the vehicle roof. Do not drill into the roof of the vehicle
for any reason.

SAFETY 129
Rollover Events
Side Air Bags and seat belt pretensioners are designed to
activate in certain rollover events. The Occupant Restraint
Controller (ORC) determines whether deployment in a
particular rollover event is appropriate, based on the
severity and type of collision. Vehicle damage by itself is not
a good indicator of whether or not Side Air Bags and seat belt
pretensioners should have deployed.
The Side Air Bags and seat belt pretensioners will not deploy
in all rollover events. The rollover sensing system deter-
mines if a rollover event may be in progress and whether
deployment is appropriate. In the event the vehicle experi -
ences a rollover or near rollover event, and deployment is
appropriate, the rollover sensing system will deploy the side
air bags and seat belt pretensioners on both sides of the
vehicle.
The SABICs may help reduce the risk of partial or complete
ejection of vehicle occupants through side windows in
certain rollover or side impact events. Air Bag System Components

158 STARTING AND OPERATING
Cold Weather Operation
To ensure reliable starting at low temperatures, use of an
externally powered electric engine block heater (available
from your authorized dealer) is recommended.
To prevent possible engine damage while starting at low
temperatures, this vehicle will inhibit engine cranking when
the ambient temperature is less than -31°F (-35° C) and the oil
temperature sensor reading indicates an engine block heater
has not been used. The message “plug in engine heater” will
be displayed in the instrument cluster when the ambient
temperature is below -25°F (-32° C) at the time the engine is
shut off as a reminder.
Extended Park Starting
NOTE:
Extended Park condition occurs when the vehicle has not
been started or driven for at least 30 days.
1. Install a battery charger or jumper cables to the battery toensure a full battery charge during the crank cycle.
2. Cycle the ignition to the AVV/”START” position and release it when the engine starts. 3. If the engine fails to start within ten seconds, cycle the
ignition to the STOP (OFF/LOCK) position, wait five
seconds to allow the starter to cool, then repeat the
Extended Park Starting procedure.
4. If the engine fails to start after eight attempts, allow the starter to cool for at least 10 minutes, then repeat the
procedure.
If Engine Fails To Start

If the engine fails to start after you have followed the "Normal
Starting" or "Extreme Cold Weather" procedure, and has not
experienced an extended park condition as identified in
"Extended Park Starting" procedure it may be flooded. Push
the accelerator pedal all the way to the floor and hold it there.
Crank the engine for no more than 15 seconds. This should
clear any excess fuel in case the engine is flooded. Leave the
ignition key in the MAR position, release the accelerator pedal
and repeat the “Normal Starting” procedure.
CAUTION!
To prevent damage to the starter, do not crank
continuously for more than 10 seconds at a time. Wait 10
to 15 seconds before trying again.

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.

176 STARTING AND OPERATING
ParkSense Rear Park Assist Sensors

The four ParkSense sensors, located in the rear fascia/bumper,
monitor the area behind the vehicle that is within the sensors’
field of view. The sensors can detect obstacles, in the horizontal
direction, from approximately 12 inches (30 cm) up to 55 inches
(140 cm) from the center of the rear fascia/bumper and up to
24 inches (60 cm) from the corners of the rear fascia/bumper,
depending on the location, type and orientation of the obstacle.

ParkSense Rear Park Assist Sensors Locations If several obstacles are detected, the ParkSense system indi
-
cates the nearest obstacle.
The minimum height of a detectable obstacle corresponds to
the maximum height of an obstacle that would clear the
underside of the vehicle during the parking maneuver.
ParkSense Rear Park Assist Alerts
If an obstacle is behind the vehicle when REVERSE gear is
engaged, an audible alert is activated.
The tones emitted by the loudspeaker inform the driver that
the vehicle is approaching an obstacle. The pauses between
the tones are directly proportional to the distance from the
obstacle. Pulses emitted in quick succession indicate the
presence of a very close obstacle. A continuous tone indicates
that the obstacle is less than 12 inches (30 cm) away.
2020_RAM_PROMASTER_CITY_OM_USA=GUID-7B6A7FCA-79B0-423F-95C5-ED2A949C3D13=1=en=.book Page 176

STARTING AND OPERATING 177
While audible signals are emitted, the audio system is
muted.
The audible signal is turned off immediately if the distance
increases. The tone cycle remains constant if the distance
measured by the inner sensors is constant. If this condition occurs
for the external sensors, the signal is turned off after three seconds
(stopping warnings during maneuvers parallel to walls).

ParkSense Rear Park Assist Failure Indications
A malfunction of the ParkSense sensors or system is indi
-
cated, during REVERSE gear engagement, by the instrument
panel warning icon.
The warning icon is illuminated and a message is
displayed on the instrument cluster display (if
equipped). Refer to “Warning Lights And
Messages” in “Getting To Know Your Instrument Panel” for
further information.

The sensors and wiring are tested continuously when the
ignition is in the MAR (ACC/ON/RUN) position. Failures are
indicated immediately if they occur when the system is on.

Even if the system is able to identify that a specific sensor is
in failure condition, the instrument cluster display shall
indicate that the ParkSense system is unavailable, without
reference to the sensor in failure condition. If even a single
sensor fails, the entire system must be disabled. The system
is turned off automatically.

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.
