(Continued)
Cleaning The ParkSense System
Clean the ParkSense sensors with water, car wash soap and
a soft cloth. Do not use rough or hard cloths. Do not scratch
or poke the sensors. Otherwise, you could damage the
sensors.
ParkSense System Usage Precautions
NOTE:
• Ensure that the rear bumper is free of snow, ice, mud, dirtand debris to keep the ParkSense system operating prop -
erly.
• Jackhammers, large trucks, and other vibrations could affect the performance of ParkSense.
• When you move the gear selector into REVERSE with ParkSense turned off, the instrument cluster display will
show "Off" on the vehicle graphic arcs for as long as the
vehicle is in REVERSE.
• ParkSense, when on, will reduce the volume of the radio when it is sounding a tone. • 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 Park -
Sense 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.
• Ensure the ParkSense system is OFF if objects such as bicycle carriers, trailer hitches, etc., are placed within
18 inches (45 cm) of the rear fascia/bumper while driving
the vehicle. Failure to do so can result in the system misin -
terpreting a close obstacle as a sensor problem, causing the
"Rear ParkSense Unavailable Service Required" message
to appear in the instrument 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 317
PARKSENSE FRONT AND REAR PARK ASSIST
The ParkSense Park Assist system provides visual and
audible indications of the distance between the rear, and/or
front fascia/bumper, and a detected obstacle when backing
up or moving forward, e.g. during a parking maneuver.
Refer to “ParkSense System Usage Precautions” in this
section for limitations of this system and recommendations.
ParkSense will retain the last system state (enabled or
disabled) from the last ignition cycle when the ignition is
changed to the ON/RUN position.
ParkSense can be active only when the gear selector is in
REVERSE or DRIVE. If ParkSense is enabled at one of these
gear selector positions, the system will remain active until
the vehicle speed is increased to approximately 7 mph
(11 km/h) or above. A warning will appear in the instrument
cluster display when the vehicle is in REVERSE, indicating
the vehicle is above ParkSense operating speed. The system
will become active again if the vehicle speed is decreased to
speeds less than approximately 6 mph (9 km/h).
• 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.

318 STARTING AND OPERATING
ParkSense Sensors
For the 3500, 4500 and 5500 Chassis Cab vehicles, the rear
ParkSense sensors are shipped loose. Please refer to the Ram
Body Builders Guide for more information.
The four ParkSense sensors are to be located in the rear
fascia/bumper, and monitor the area behind the vehicle that
is within the sensors’ field of view.
The sensors can detect obstacles from approximately
18 inches (45 cm) up to 79 inches (200 cm) from the rear
fascia/bumper in the horizontal direction, depending on the
location, type and orientation of the obstacle.
NOTE:
If equipped as a dually, the ParkSense system has six rear
sensors to assist in detection around the dually flares.

The six ParkSense sensors, located in the front fascia/bumper,
monitor the area in front of the vehicle that is within the
sensors’ field of view. The sensors can detect obstacles from
approximately 12 inches (30 cm) up to 47 inches (120 cm) from
the front fascia/bumper in the horizontal direction, depending
on the location, type and orientation of the obstacle.

ParkSense Warning Display
The ParkSense Warning screen is located within the instru-
ment cluster display. It provides visual warnings to indicate
the distance between the rear fascia/bumper and/or front
fascia/bumper and the detected obstacle. Refer to “Instru-
ment Cluster Display” in “Getting To Know Your Instru-
ment Panel” for further information.
ParkSense Display
The warning display will turn on indicating the system
status when the vehicle is in REVERSE or when the vehicle is
in DRIVE and an obstacle has been detected.
The system will indicate a detected obstacle by showing a
single arc in the left and/or right rear regions based on the
obstacle’s distance and location relative to the vehicle.

322 STARTING AND OPERATING
The vehicle is close to the obstacle when the display shows one flashing arc and sounds a continuous tone. The following chart

When the Rear View Camera image is being displayed, and
the vehicle speed is below 8 mph (13 km/h) while in any
gear selector position, Zoom View is available. By pressing
the “magnifying glass” icon in the upper left of the display
screen, the image will zoom in to four times the standard
view. Pressing the icon a second time will return the view to
the standard Backup Camera display.
When Zoom View is selected while the vehicle is in
REVERSE, then shifted to DRIVE, the camera delay view will
display the standard Backup Camera view. If the vehicle is
then returned to REVERSE gear from DRIVE, the Zoom
View selection will automatically resume.
Shifting to NEUTRAL from any gear will maintain the
selected view (Zoom or Standard) as long as the vehicle is
below 8 mph (13 km/h).
If the vehicle is in PARK, Zoom View is available until the
gear selector is placed in DRIVE or REVERSE and speeds are
at or above 8 mph (13 km/h).
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.

Once activated, the image will continue to be displayed in
any gear until the vehicle speed exceeds 8 mph (13 km/h).REFUELING THE VEHICLE — GAS
NOTE:
When the fuel nozzle “clicks” or shuts off the fuel tank is full.
WARNING!
Drivers must be careful when backing up even when
using the Surround View 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, Surround View should only be used as a parking aid. The Surround View 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 Surround View 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 Surround View.
CAUTION!
• Damage to the fuel system or emissions control system could result from using an improper fuel tank filler
tube cap (fuel filler cap). A poorly fitting cap could let
impurities into the fuel system. Also, a poorly-fitted
aftermarket cap can cause the MIL (Malfunction Indi -
cator Light) to illuminate due to fuel vapors escaping
from the system.
• A poorly fitting fuel filler cap may cause the MIL to turn on.
• To avoid fuel spillage and overfilling, do not “top off” the fuel tank after filling.
WARNING!
• Never have any smoking materials lit in or near the vehicle when the gas cap is removed or the tank is
being filled.

STARTING AND OPERATING 337
NOTE:
Tighten the gas cap ¼ turn until you hear one click. This is an
indication that the cap is properly tightened.
If the gas cap is not tightened properly, the Malfunction Indi-
cator Light will come on. Be sure the gas cap is tightened
every time the vehicle is refueled.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that the
fuel filler cap is loose, improperly installed, or
damaged, a loose gascap indicator will display in the
instrument cluster telltale display area. Refer to “Instrument
Cluster Display” in “Getting To Know Your Instrument
Panel” for further information. Tighten the fuel filler cap
properly and push the RIGHT button to turn off the message.
If the problem continues, the message will appear the next
time the vehicle is started.
VEHICLE LOADING
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total permissible weight of your vehicle
including driver, passengers, vehicle, options and cargo. The
label also specifies maximum capacities of front and rear axle
systems (GAWR). Total load must be limited so GVWR and
front and rear GAWR are not exceeded.
• Never add fuel to the vehicle when the engine is
running. This is in violation of most state and federal
fire regulations and may cause the MIL to turn on.
WARNING!
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.
