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,
dirt and debris to keep the ParkSense system operating
properly.
• Jackhammers, large trucks, and other vibrations could
affect the performance of ParkSense.
• When you turn ParkSense off, the instrument cluster
display will show  PARKSENSE OFF  . Furthermore,
once you turn ParkSense off, it remains off until you turn
it on again, even if you cycle the ignition key.
• When you move the gear selector to the REVERSE
position and ParkSense is turned off, the instrument
cluster display will show the  PARKSENSE OFF  mes-
sage 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 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.
• Ensure the ParkSense system is OFF if objects such as
bicycle carriers, trailer hitches, etc., are placed within 18
inches (45 cm) from the rear fascia/bumper while driv-
ing the vehicle. Failure to do so can result in the system
misinterpreting a close obstacle as a sensor problem,
causing the  PARKSENSE UNAVAILABLE SERVICE
REQUIRED  message to appear in the instrument cluster
display.
• On vehicles equipped with a tailgate, ParkSense should
be disabled when the tailgate is in the lowered or open
position and the vehicle is in REVERSE. A lowered
tailgate could provide a false indication that an obstacle
is behind the vehicle.148 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

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 respon-
sible for safety and must continue to pay attention to
your surroundings. Failure to do so can result in
serious injury or death.
• Before using ParkSense, it is strongly recommended
that the ball mount and hitch ball assembly is
disconnected 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 con-
tinuous 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
ParkSense 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. 3UNDERSTANDING THE FEATURES OF YOUR VEHICLE 149

PARKSENSE FRONT AND REAR PARK ASSIST —
IF EQUIPPED
The ParkSense Park Assist system provides visual and
audible indications of the distance between the rear and/or
front fascia 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 instru-
ment cluster display 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). 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, 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
from approximately 18 inches (45 cm) up to 79 inches (200
cm) from the rear fascia/bumper in the horizontal direc-
tion, depending on the location, type and orientation of the
obstacle.
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.150 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

PARKVIEW REAR BACK UP CAMERA — IF
EQUIPPED
Your vehicle may be equipped with the ParkView Rear
Back Up Camera that allows you to see a image of the rear
surroundings of your vehicle whenever the gear selector is
put into REVERSE or whenever it is initiated through
 Backup Camera  button in the  Controls  menu. Whenever
the gear selector is put into REVERSE, the image will be
displayed in the rearview mirror display (if equipped) or
Uconnect screen (if equipped) along with a caution note to
“check entire surroundings” across the top of the screen.
After five seconds this note will disappear.156 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver ’s responsibility to main-
tain correct tire pressure, even if under-inflation has not
reached the level to trigger illumination of the TPMS low
tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunc-
tion indicator to indicate when the system is not operating
properly. The TPMS malfunction indicator is combined
with the low tire pressure telltale. When the system detects
a malfunction, the telltale will flash for approximately one
minute and then remain continuously illuminated. This
sequence will continue upon subsequent vehicle start-ups
as long as the malfunction exists. When the malfunction
indicator is illuminated, the system may not be able to
detect or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons, including
the installation of replacement or alternate tires or wheels
on the vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction telltale after
replacing one or more tires or wheels on your vehicle, to
ensure that the replacement or alternate tires and wheels
allow the TPMS to continue to function properly. CAUTION!The TPMS has been optimized for the original equip-
ment tires and wheels. TPMS pressures and warning
have been established for the tire size equipped on
your vehicle. Undesirable system operation or sensor
damage may result when using replacement equip-
ment that is not of the same size, type, and/or style.
Aftermarket wheels can cause sensor damage. Using
aftermarket tire sealants may cause the Tire Pressure
Monitoring System (TPMS) sensor to become inoper-
able. After using an aftermarket tire sealant it is
recommended that you take your vehicle to an autho-
rized dealership to have your sensor function checked. 4UNDERSTANDING YOUR INSTRUMENT PANEL 209

Battery Saver On/Battery Saver Mode Message —
Electrical Load Reduction Actions — If Equipped
This vehicle is equipped with an Intelligent Battery Sensor
(IBS) to perform additional monitoring of the electrical
system and status of the vehicle battery.
In cases when the IBS detects charging system failure, or
the vehicle battery conditions are deteriorating, electrical
load reduction actions will take place to extend the driving
time and distance of the vehicle. This is done by reducing
power to or turning off non-essential electrical loads. Load reduction is only active when the engine is running.
It will display a message if there is a risk of battery
depletion to the point where the vehicle may stall due to
lack of electrical supply, or will not restart after the current
drive cycle.
When load reduction is activated, the message “Battery
Saver On” or “Battery Saver Mode” will appear in the
instrument cluster.
These messages indicate the vehicle battery has a low state
of charge and continues to lose electrical charge at a rate
that the charging system cannot sustain.
NOTE:
• The charging system is independent from load reduc-
tion. The charging system performs a diagnostic on the
charging system continuously.
• If the Battery Charge Warning Light is on it may indicate
a problem with the charging system. Refer to “Battery
Charge Warning Light” in “Understanding Your Instru-
ment Panel” for further information.232 UNDERSTANDING YOUR INSTRUMENT PANEL
