average, you will prefer the shoulder belt
anchorage in a higher position. After you
release the anchorage button, try to move it up
or down to make sure that it is locked in
position. NOTE:
The adjustable upper shoulder belt anchorage
is equipped with an Easy Up feature. This
feature allows the shoulder belt anchorage to
be adjusted in the upward position without
pushing or squeezing the release button. To
verify the shoulder belt anchorage is latched,
pull downward on the shoulder belt anchorage
until it is locked into position.
WARNING!

Wearing your seat belt incorrectly could
make your injuries in a collision much worse.
You might suffer internal injuries, or you
could even slide out of the seat belt. Follow
these instructions to wear your seat belt
safely and to keep your passengers safe, too.

Position the shoulder belt across the
shoulder and chest with minimal, if any
slack so that it is comfortable and not
resting on your neck. The retractor will with
-
draw any slack in the shoulder belt.
Misadjustment of the seat belt could
reduce the effectiveness of the safety belt
in a crash.
Always make all seat belt height adjust -
ments when the vehicle is stationary.

Summary Of Recommendations For Restraining Children In Vehicles
Infant And Child Restraints
Safety experts recommend that children ride
rear-facing in the vehicle until they are two years
old or until they reach either the height or
weight limit of their rear-facing child restraint.
Two types of child restraints can be used
rear-facing: infant carriers and convertible child
seats.
The infant carrier is only used rear-facing in the
vehicle. It is recommended for children from
birth until they reach the weight or height limit of the infant carrier. Convertible child seats can be
used either rear-facing or forward-facing in the
vehicle. Convertible child seats often have a
higher weight limit in the rear-facing direction
than infant carriers do, so they can be used
rear-facing by children who have outgrown their
infant carrier but are still less than at least two
years old. Children should remain rear-facing
until they reach the highest weight or height
allowed by their convertible child seat.
Child Size, Height, Weight Or Age Recommended Type Of Child Restraint
Infants and Toddlers
Children who are two years old or younger and
who have not reached the height or weight limits of their child restraint Either an Infant Carrier or a Convertible Child
Restraint, facing rearward in a rear seat of the vehicle
Small Children Children who are at least two years old or who
have outgrown the height or weight limit of their rear-facing child restraint Forward-Facing Child Restraint with a five-point
Harness, facing forward in a rear seat of the vehicle
Larger Children Children who have outgrown their forward-facing
child restraint, but are too small to properly fit the vehicle’s seat belt Belt Positioning Booster Seat and the vehicle
seat belt, seated in a rear seat of the vehicle
Children Too Large for Child Restraints Children 12 years old or younger, who have
outgrown the height or weight limit of their booster seat Vehicle Seat Belt, seated in a rear seat of the
vehicle
WARNING!
Never place a rear-facing child restraint in
front of an air bag. A deploying passenger
front air bag can cause death or serious
injury to a child 12 years or younger,
including a child in a rear-facing child
restraint.

20_DJD2_OM_EN_USC_t.book Page 192

SAFETY193
Older Children And Child Restraints
Children who are two years old or who have
outgrown their rear-facing convertible child seat
can ride forward-facing in the vehicle.
Forward-facing child seats and convertible child
seats used in the forward-facing direction are
for children who are over two years old or who
have outgrown the rear-facing weight or height
limit of their rear-facing convertible child seat.
Children should remain in a forward-facing child
seat with a harness for as long as possible, up
to the highest weight or height allowed by the
child seat.
All children whose weight or height is above the
forward-facing limit for the child seat should use
a belt-positioning booster seat until the
vehicle’s seat belts fit properly. If the child
cannot sit with knees bent over the vehicle’s
seat cushion while the child’s back is against
the seatback, they should use a belt-positioning
booster seat. The child and belt-positioning
booster seat are held in the vehicle by the seat
belt.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!
Do not install a rear-facing car seat using a
rear support leg in this vehicle. The floor of
this vehicle is not designed to manage the
crash forces of this type of car seat. In a
crash, the support leg may not function as it
was designed by the car seat manufacturer,
and your child may be more severely injured
as a result.
WARNING! (Continued)WARNING!
Improper installation can lead to failure of
an infant or child restraint. It could come
loose in a collision. The child could be badly
injured or killed. Follow the child restraint
manufacturer’s directions exactly when
installing an infant or child restraint.
After a child restraint is installed in the
vehicle, do not move the vehicle seat
forward or rearward because it can loosen
the child restraint attachments. Remove
the child restraint before adjusting the
vehicle seat position. When the vehicle seat
has been adjusted, reinstall the child
restraint.
When your child restraint is not in use,
secure it in the vehicle with the seat belt or
LATCH anchorages, or remove it from the
vehicle. Do not leave it loose in the vehicle.
In a sudden stop or accident, it could strike
the occupants or seatbacks and cause
serious personal injury.

256STARTING AND OPERATING
AIR SUSPENSION SYSTEM — 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 the
ON/RUN position or the engine running with
zero vehicle speed for all user requested
changes and load leveling.

Rear Leveling Ride Height Switch
Normal Ride Height (NRH)
– This is the standard
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 inch (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
suspension system will continue to load level
after the vehicle has been turned off for
10 minutes without compressor activation. This
allows for easy removal of a trailer and/or load
from the back of the truck by maintaining the
ride height. After 10 minutes you will need to
turn the ignition to the run position for the air
suspension to re-level due to addition/removal
of load in the vehicle. If the air suspension
system is disabled using the settings menu (Tire
Jack Mode, Transport Mode, Alignment Mode,
or Bed Lowering Mode) the system will remain
disabled when the vehicle is turned off.
Reactivating the air suspension can be
accomplished via the settings menu or driving the vehicle above 5 mph (8 km/h) for Tire Jack
Mode, Alignment Mode, Transport Mode and
Bed Lowering Mode.
NOTE:
Most 3500 models will not lower to Alternate
Trailer Height (ATH) when unloaded.
Refer to “Trailer Towing” in “Starting And
Operating” for further information.
AIR SUSPENSION MODES
The air suspension system has multiple modes
to protect the system in unique situations:
Tire/Jack Mode
To assist with changing a tire, the air
suspension system has a feature which allows
the automatic leveling to be disabled. This
mode is intended to be enabled with the engine
running. Refer to “Instrument Cluster Display”
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 an authorized dealer for service.
