AIR SUSPENSION SYSTEM
(2500/3500 MODELS) — IF
EQUIPPED
Description
This air suspension system is a rear leveling
ride height system. The main purpose of this
system is to maintain the truck’s rear ride
height level. There are two selectable heights
that can be chosen based on your operating
conditions.
The system requires that the ignition be in
ON/RUN position or the engine running with
zero vehicle speed for all user requested
changes and load leveling.
STARTING AND OPERATING
174

Normal Ride Height (NRH)– This is the stan-
dard position of the suspension and is meant
for normal driving. It will automatically adjust
to maintain the rear ride height as conditions
change.
Alternate Trailer Height (ATH) – Lowers the
vehicle approximately 1 in (25 mm) for a
level truck, to be used as required while
trailer towing. It will automatically adjust to
maintain the rear ride height as conditions
change.
Trailer Decoupling/Unloading - The air suspen-
sion system will load level (lower/exhaust
only) for up to 10 minutes after the vehicle is
turned off. This allows for easy removal of a trailer and/or load from the back of the truck
by maintaining the ride height. After 10 min-
utes you will need to turn the ignition to the
run position for the air suspension to main-
tain ride height. If the air suspension system
is disabled using the settings menu (Tire Jack
Mode, Transport Mode or Alignment Mode)
the system will remain disabled when the
vehicle is turned off. Reactivating the air
suspension can be accomplished via the set-
tings menu or driving the vehicle above
5 mph (8 km/h) for Tire Jack Mode or Align-
ment Mode and 16 mph (26 km/h) for Trans-
port Mode.
NOTE:
• Most 3500 models will not lower to Alter-
nate Trailer Height (ATH) when unloaded.
• Refer to “Trailer Towing” in “Starting And Operating” for further information.
Ignition OFF Behavior
For a predetermined amount of time after the
ignition is off the air suspension may adjust
to maintain a proper appearance.
Refer to your Owner’s Manual for further
information.
WARNING!
The air suspension system uses a high
pressure volume of air to operate the sys-
tem. To avoid personal injury or damage to
the system, see your authorized dealer for
service.

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. Re-
fer to “ParkSense System Usage Precau-
tions” in the Owner’s Manual 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 indicating the vehicle is aboveParkSense operating speed. The system will
become active again if the vehicle speed is
decreased to speeds less than approximately
6 mph (9 km/h).
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.
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 the "Backup Camera" button in the
"Controls" menu. Whenever the gear selector
is put into REVERSE, the image will be dis-
played 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.
The ParkView Camera is located to the left of
the tailgate handle.
When the vehicle is shifted out of REVERSE
(with Camera delay turned off), the rear Cam-
era mode is exited and the navigation or audio
screen appears again.
When the vehicle is shifted out of REVERSE
(with Camera delay turned on), the rear Cam-
era image will be displayed for up to 10 sec-
onds after shifting out of REVERSE unless
the forward vehicle speed exceeds 8 mph
(13 km/h), the transmission is shifted into
PARK or the ignition is switched to the OFF
position.
Whenever the Rear View Camera image is
activated through the "Backup Camera" but-
ton in the "Controls" menu, a display timer for
the image is initiated. The image will con-
tinue to be displayed until the display timer
exceeds 10 seconds and the vehicle speed is
above 8 mph (13 km/h) or the touchscreen
button "X" to disable display of the Rear View
Camera image is pressed.

REFUELING THE VEHICLE — GAS
ENGINE
The fuel filler cap (gas cap) is located behind
the fuel filler door, on the left side of the
vehicle. Open the fuel door and remove the
fuel cap by turning it counter-clockwise.
NOTE:
When removing the fuel filler cap, lay the cap
tether in the hook, located on the fuel filler
door.
WARNING!
• Never have any smoking materials lit inor near the vehicle when the gas cap is
removed or the tank is being filled.
• Never add fuel to the vehicle when the
engine is running.
• 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.
CAUTION!
• Damage to the fuel system or emissionscontrol system could result from using
an improper fuel tank filler tube cap.
• A poorly fitting fuel filler cap could let
impurities into the fuel system.
• A poorly fitting fuel filler cap may cause
the “Malfunction Indicator Light (MIL)”
to turn on.
• To avoid fuel spillage and overfilling, do
not “top off” the fuel tank after filling.
When the fuel nozzle “clicks” or shuts
off, the fuel tank is full.
NOTE:
• When the fuel nozzle “clicks” or shuts off, the fuel tank is full.
• Tighten the gas cap until you hear a “click- ing” sound. This is an indication that the
gas cap is tightened properly. The MIL in
the instrument cluster may turn on if the
gas cap is not secured properly. Make sure
that the gas cap is tightened each time the
vehicle is refueled.
WARNING!
Static electricity can cause an ignition of
flammable liquid, vapor or gas in any ve-
hicle or trailer. To reduce risk of serious
injury or death when filling containers:
• Always place container on the ground before filling.
• Keep the pump nozzle in contact with
the container when you are filling it.
• Use only approved containers for flam-
mable liquid.
• Do not leave container unattended while
filling.
• A static electric charge could cause a
spark and fire hazard.
181

The DEF injection system consists of the
following components:
• DEF tank
• DEF pump
• DEF injector
• Electronically-heated DEF lines
• NOx sensors
• Temperature sensors
• SCR catalyst
The DEF injection system and SCR catalyst
enable the achievement of diesel emissions
requirements; while maintaining outstanding
fuel economy, drivability, torque and power
ratings.
Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for
system messages and warnings.
NOTE:
• Your vehicle is equipped with a DEF injec-tion system. You may occasionally hear an
audible clicking noise from under the ve-
hicle at a stop. 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 and may
be audible from the rear of the vehicle.
Adding Diesel Exhaust Fluid
The DEF gauge (located on the instrument
cluster) will display the level of DEF remain-
ing in the tank. Refer to “Instrument Cluster”
and “Instrument Cluster Descriptions” in
“Getting To Know Your Instrument Panel” for
further information.
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 con-
ditions, 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 sys-
tem. • 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:
Refer to “Fluids And Lubricants” in “Techni-
cal Specifications” for the correct fluid type.
1. Remove cap from DEF tank (located on
drivers side of the vehicle or in fuel door).
