SURROUND VIEW CAMERA SYSTEM — IF
EQUIPPED

Your vehicle may be equipped with the Surround
View Camera system that allows you to see an
on-screen image of the surroundings and Top
View of your vehicle whenever the gear selector is
put into REVERSE or manually activated via the
Uconnect system. The Top View of the vehicle will
show which doors are open. The image will be
displayed on the touchscreen display along with
a caution note “Check Entire Surroundings”
across the top of the screen. After five seconds,
this note will disappear. The Surround View
Camera system is comprised of three sequential
cameras located in the front grille and side
mirrors, in addition to a fourth Rear Back Up
Camera.
NOTE:

For the 3500, 4500, and 5500 Chassis Cab vehi
-
cles, the Rear Backup Camera is shipped loose
and not installed. Please refer to the Ram Body
Builder’s Guide for more information.

The Surround View Camera system has
programmable settings that may be selected
through the Uconnect system Ú page 228.
Press this button on the touchscreen
to enter the Surround View Camera
menu in the Uconnect system.
When the vehicle is shifted into REVERSE, the
Rear View and Top View is the default view of
the system.
If the camera delay is turned on, the camera
image will display for up to 10 seconds after
shifting out of REVERSE. The camera image will
not display for 10 seconds if the vehicle speed
exceeds 8 mph (13 km/h), the vehicle is shifted
into PARK, or the ignition is placed in the OFF
position. The “X” button on the touchscreen
disables the display of the camera image.
If the camera delay is turned off, the camera
image will close and display the previous screen
after shifting out of REVERSE. If active guidelines are enabled, the lines are
overlaid on the image in the Rear View to
illustrate the width of the vehicle. The view
will also include the side view mirrors and its
projected back up path based on the steering
wheel position.
There are different colored zones to indicate the
distance to the rear of the vehicle. Refer to the
chart below:
Modes Of Operation
Standard Rear View can be manually activated
by selecting “Back Up Camera” through the
Controls menu within the Uconnect system.

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 Ú page 90. 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.
REFUELING THE VEHICLE — DIESEL ENGINE
NOTE:
When the fuel nozzle “clicks” or shuts off, the
fuel tank is full.
Tighten the fuel filler cap until you hear a
“clicking” sound. This is an indication that the
fuel filler cap is properly tightened.
Make sure that the fuel filler cap is tightened
each time the vehicle is refueled.
DIESEL EXHAUST FLUID
Your vehicle is equipped with a Selective
Catalytic Reduction (SCR) system to meet the
very stringent diesel emissions standards
required by the Environmental Protection
Agency.

The purpose of the SCR system is to reduce levels
of NOx (oxides of nitrogen emitted from engines)
that are harmful to our health and the
environment to a near-zero level. A small quantity
of Diesel Exhaust Fluid (DEF) is injected into the
exhaust upstream of a catalyst where, when
vaporized, it converts smog-forming nitrogen
oxides (NOx) into harmless nitrogen (N2) and
water vapor (H2O), two natural components of
the air we breathe. You can operate with the
comfort that your vehicle is contributing to a
cleaner, healthier world environment for this and
generations to come.

System Overview
This vehicle is equipped with a Diesel Exhaust
Fluid (DEF) injection system and a Selective
Catalytic Reduction (SCR) catalyst to meet the
emission requirements.
The DEF injection system consists of the
following components:
DEF tank
DEF pump
DEF injector
Electronically-heated DEF lines
DEF control module
NOx sensors
Temperature sensors
SCR catalyst
UQS Sensor
For system messages and warnings Úpage 90.
CAUTION!
To avoid fuel spillage and overfilling, do not
“top off” the fuel tank after filling.
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.

21_DPF_OM_EN_USC_t.book Page 196

STARTING AND OPERATING197
NOTE:

Your vehicle is equipped with a DEF injection
system. You may occasionally hear an audible
clicking noise. This is normal operation.

The DEF pump will run for a period of time
after engine shutdown to purge the DEF
system. This is normal operation.
Diesel Exhaust Fluid Storage

Diesel Exhaust Fluid (DEF) is considered a very
stable product with a long shelf life. If DEF is kept
in temperatures between 10° and 90°F (-12°
and 32°C), it will last a minimum of one year.

DEF is subject to freezing at the lowest
temperatures. For example, DEF may freeze
at temperatures at or below 12°F (-11°C).
The system has been designed to operate in
this environment.
NOTE:

When working with DEF, it is important to know that:

Any containers or parts that come into contact
with DEF must be DEF compatible (plastic or
stainless steel). Copper, brass, aluminum, iron or non-stainless steel should be avoided as
they are subject to corrosion by DEF.

If DEF is spilled, it should be wiped up
completely.
Adding Diesel Exhaust Fluid (DEF)
The DEF gauge (located on the instrument
cluster) will display the level of DEF remaining in
the tank Ú
page 90.
NOTE:
Driving conditions (altitude, vehicle speed,
load, etc.) will effect the amount of DEF that
is used in your vehicle.
Another factor is that outside temperature
can affect DEF consumption. In cold condi -
tions, 12°F (-11°C) and below, the DEF
gauge needle can stay on a fixed position and
may not move for extended periods of time.
This is a normal function of the system.
There is an electric heater inside the DEF
tank that automatically works when neces -
sary. And if the DEF supply does freeze, the
truck will operate normally until it thaws. DEF Fill Procedure
NOTE:
For the correct fluid type Ú
page 440.
Remove cap from DEF tank (located on drivers
side of the vehicle or in fuel door).
