2015 Ram ProMaster City sensor

Mode and activate the vehicle sensitive (emergency)
locking mode.
WARNING!
•The seat belt assembly must be replaced if the
switchable Automatic Locking Retractor (ALR) fea-
ture or any other seat belt function is not working
properly when checked according to the proce-
dures in the Service Manual.
• Failure to replace the seat belt assembly could
increase the risk of injury in collisions.
• Do not use the Automatic Locking Mode to restrain
occupants who are wearing the seat belt or children
who are using booster seats. The locked mode is
only used to install rear-facing or forward-facing
child restraints that have a harness for restraining
the child.

46 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
•Being too close to the steering wheel or instrument
panel during Advanced Front Air Bag deployment
could cause serious injury, including death. Air
bags need room to inflate. Sit back, comfortably
extending your arms to reach the steering wheel or
instrument panel.
• Never place a rear-facing child restraint in front of
an air bag. A deploying Passenger Advanced 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.
• Only use a rear-facing child restraint in a vehicle
with a rear seat.
Advanced 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
determined by the Occupant Restraint Controller (ORC),
which may receive information from the front impact
sensors 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.
48 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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 colli-
sions, and also are needed to help keep you in position,
away from an inflating air bag.
When the ORC detects a collision requiring the Ad-
vanced Front Air Bags, it signals the inflator units. A large
quantity of non-toxic gas is generated to inflate the
Advanced Front Air Bags.
The steering wheel hub trim cover and the upper right
side of the instrument panel separate and fold out of the
way as the air bags inflate to their full size. The Advanced
Front Air Bags fully inflate in less time than it takes to
blink your eyes. The 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 occu-
pants for improved interaction with the Advanced 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.
Supplemental Driver Knee Air Bag
This vehicle is equipped with a Supplemental Driver
Knee Air Bag mounted in the instrument panel below the
steering column. The Supplemental Driver Knee Air Bag
50 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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 Advanced
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. Occupants, including children, who are
up against or very close to Side Air Bags can be seriously
injured or killed. Occupants, including children, should
never lean on or sleep against the door, side windows, or
area where the Side Air Bags inflate, even if they are in an
infant or child restraint.
Seat belts (and child restraints where appropriate) are
necessary for your protection in all collisions. They also
help keep you in position, away from inflating Side Air
Bags. To get the best protection from the Side Air Bags,
occupants must wear their seat belts properly and sit
upright with their backs against the seats. Children must
be properly restrained in a child restraint or booster seat
that is appropriate for the size of the child.

The ParkSense® Rear Park Assist is automatically acti-
vated when the transmission is placed into REVERSE. As
the distance from an obstacle behind the vehicle de-
creases, the audible alert becomes more frequent.
Interaction With Trailer Towing
The Rear Park Assist system is automatically deactivated
when a trailer is hitched to the vehicle. The system will be
automatically activated as soon as the trailer is removed.
ParkSense® Rear Park Assist Sensors
The four ParkSense® Rear Park Assist sensors, located in
the rear fascia/bumper, monitor the area behind the ve-
hicle that is within the sensors’ field of view. The sensors
can detect obstacles, in the horizontal direction, from
approximately 12 in (30 cm) up to 55 in (140 cm) from the
center of the rear fascia/bumper and up to 24 in (60 cm)
from the corners of the rear fascia/bumper, depending on
the location, type and orientation of the obstacle.

(dashboard loudspeaker)
• Sound pulses emitted at a rate that increases as
the distance decreases.
• Emits continuous tone at 12 in (30 cm).

While audible signals are emitted, the audio system is not
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® Rear Park Assist sen-
sors or system is indicated, during REVERSE gear en-
gagement, by the instrument panel warning icon.The warning icon is illuminated and a message
is displayed on the multifunction display (if
equipped). Refer to “Instrument Cluster De-
scriptions” in “Understanding Your Instrument
Panel” for further information. The sensors and wiring are tested continuously when the
ignition is in the ON/RUN position. Failures are indi-
cated 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® Rear Park Assist
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® Rear Park Assist sensors with
water, car wash soap and a soft cloth. Do not use rough
or hard cloths. In washing stations, clean sensors quickly
keeping the vapor jet/high pressure washing nozzles at
least 4 in (10 cm) from the sensors. Do not scratch or poke
the sensors. Otherwise, you could damage the sensors.
