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.
Air Suspension Modes
The air suspension system has multiple
modes to protect the system in unique situa-
tions:
Tire/Jack Mode
To assist with changing a tire, the air suspen-
sion system has a feature which allows the
automatic leveling to be disabled. This mode
is intended to be enabled with engine run-
ning. Refer to “Instrument Cluster Display”
in “Getting To Know Your Instrument Panel”
or “Uconnect Settings” in “Multimedia” if
equipped with a touch screen radio, in your

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.
