How To Engage The Automatic Locking Mode
1. Buckle the combination lap and shoulder belt.
2. Grasp the shoulder portion and pull downward until theentire seat belt is extracted.
3. Allow the seat belt to retract. As the seat belt retracts, you will hear a clicking sound. This indicates the seat belt is
now in the Automatic Locking Mode.
How To Disengage The Automatic Locking Mode
Unbuckle the combination lap/shoulder belt and allow it to
retract completely to disengage the Automatic Locking
Mode and activate the vehicle sensitive (emergency) locking
mode.
Supplemental Restraint Systems (SRS)
Some of the safety features described in this section may be
standard equipment on some models, or may be optional
equipment on others. If you are not sure, ask an authorized
dealer.
• Never install a rear-facing child restraint in the front
seat of a vehicle. Only use a rear-facing child restraint
in the rear seat. If the vehicle does not have a rear seat,
do not transport a rear-facing child restraint in that
vehicle.
WARNING! (Continued)WARNING!
• The seat belt assembly must be replaced if the switch -
able Automatic Locking Retractor (ALR) feature or any
other seat belt function is not working properly when
checked according to the procedures in the Service
Manual.
• Failure to replace the seat belt assembly could increase the risk of injury in collisions.
• Do not use the Automatic Locking Mode to restrain occupants who are wearing the seat belt or children
who are using booster seats. The locked mode is only
used to install rear-facing or forward-facing child
restraints that have a harness for restraining the child.

322 STARTING AND OPERATING
NOTE:
If equipped with a touch screen radio all enabling/disabling
of air suspension features must be done through the radio.
Refer to “Uconnect Settings” in “Multimedia” for further
information.
Air Suspension Modes
The Air Suspension system has multiple modes to protect the
system in unique situations:
Automatic AERO Mode
To improve aerodynamics, the air suspension system has a
feature which will put the vehicle into AERO height auto-
matically. Refer to “Instrument Cluster Display” in “Getting
To Know Your Instrument Panel” for further information.
Automatic Aero Mode may be disabled through vehicle
settings in the instrument cluster display or through your
Uconnect Radio if equipped. Refer to “Instrument Cluster Display” in “Getting To Know Your Instrument Panel” or
“Uconnect Settings” in “Multimedia” for further information.
NOTE:
This mode is intended to be enabled with engine running.
Tire Jack Mode
To assist with changing a tire, the air suspension system has
a feature which allows the automatic leveling to be disabled.
Refer to “Instrument Cluster Display” in “Getting To Know
Your Instrument Panel” or “Uconnect Settings” in “Multi
-
media” if equipped with a touch screen radio for further
information.
NOTE:
This mode is intended to be enabled with engine running.
Transport Mode
For towing your vehicle with four wheels off the road, the air
suspension system has a feature which will put the vehicle
into Entry/Exit height and disable the automatic load
leveling system. Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” or “Uconnect
Settings” in “Multimedia” if equipped with a touch screen
radio for further information.
NOTE:
This mode is intended to be enabled with engine running.
WARNING!
The air suspension system uses a high pressure volume
of air to operate the system. To avoid personal injury or
damage to the system, see your authorized dealer for
service.
2020_DT_1500_OM_US.book Page 322
324 STARTING AND OPERATING
The indicator lamps 1 through 5 will illuminate to show the
current position of the vehicle. Flashing indicator lamps will
show a position which the system is working to achieve.
When raising, if multiple indicator lamps are flashing, the
highest flashing indicator lamp is the position the system is
working to achieve. When lowering, if multiple indicators
are flashing, the lowest solid indicator lamp is the position
the system is working to achieve.
Pushing the height selector up once will move the suspen-
sion one position higher from the current position, assuming
all conditions are met (i.e. key in ON/RUN position, engine
running, speed below threshold, etc). The height selector
switch can be pushed up multiple times, each push will raise
the requested level by one position up to a maximum posi -
tion of OR2 or the highest position allowed based on current
conditions (i.e. vehicle speed, etc).
Pushing the height selector down once will move the suspen -
sion one position lower from the current level, assuming all
conditions are met (i.e. key in ON/RUN position, engine
running, doors closed, speed below threshold, etc). The
height selector switch can be pushed down multiple times,
each push will lower the requested level by one position
down to a minimum of Entry/Exit Mode or the lowest posi -
tion allowed based on current conditions (i.e. vehicle speed,
etc.) Automatic height changes will occur based on vehicle speed
and the current vehicle height. The indicator lamps and
instrument cluster display messages will operate the same
for automatic changes and user requested changes.
• Off-Road 2 (OR2) – Indicator lamps 5, 4, 3, 2 and 1 will be
illuminated when the vehicle is in OR2.
• Off-Road 1 (OR1) – Indicator lamps 5, 4, 3 and 2 will be illuminated when the vehicle is in OR1.
• Normal Ride Height (NRH) – Indicator lamps 5, 4 and 3 will be illuminated when the vehicle is in this position.
• Aero Mode – Indicator lamps 5 and 4 will be illuminated when the vehicle is in this position.
• Entry/Exit Mode – Indicator lamp 5 will be illuminated when the vehicle is in Entry Exit Mode. Entry/Exit mode
can be requested up to 33 mph (53 km/h). If vehicle speed
is reduced to, and kept below, 15 mph (24 km/h) indicator
lamp 4 will flash and indicator lamp 5 will remain solid
until Entry/Exit Mode is achieved at which point indicator
lamp 4 will turn off.
• Transport Mode – No indicator lamps will be illuminated. Transport Mode is disabled by driving the vehicle.
