2008 DODGE RAM 3500 CHASSIS CAB ECU

Airbags inflate in moderate to high speed impacts. Along
with the seatbelts, front airbags work with the instrument
panel knee bolsters to provide improved protection for
the driver and front passenger.
The seat belts are designed to protect you in many types
of collisions. The front airbags deploy in moderate to
severe frontal collisions. In certain types of collisions, the
front airbags may be triggered. But even in collisions
where the airbags work, you need the seat belts to keep
you in the right position for the airbags to protect you
properly.
Here are some simple steps you can follow to minimize
the risk of harm from a deploying airbag.
²Children 12 years and under should ride buckled up in
a rear seat, if available.
²Infants in rear facing child restraints mustNEVER
ride in the front seat of a vehicle with a passenger frontairbagunless the airbag is turned off(Standard Cab
Vehicles Only). An airbag deployment can cause se-
vere injury or death to infants in that position. See the
Passenger Airbag On/Off Switch (If Equipped) sec-
tion.
²If your vehicle does not have a rear seat, see the
Passenger Airbag On/Off Switch (If Equipped) sec-
tion.
²Children that are not big enough to properly wear the
vehicle seat belt (see section on Child Restraints)
should be secured in the rear seat in child restraints or
belt-positioning booster seats. Older children who do
not use child restraints or belt-positioning booster
seats should ride properly buckled up in the rear seat.
Never allow children to slide the shoulder belt behind
them or under their arm.
²All occupants should use their seat belts properly.

²Airbag deployment level (if applicable)
²Impact acceleration and angle
²Seatbelt status
²Brake status (service and parking brakes)
²Accelerator status (including vehicle speed)
²Engine control status (including engine speed)
²Transmission gear selection
²Cruise control status
²Traction/stability control status
²Tire pressure monitoring system status (if equipped)
Child Restraint
Everyone in your vehicle needs to be buckled up all the
time Ð babies and children, too. Every state in the United
States and all Canadian provinces require that small
children ride in proper restraint systems. This is the law,
and you can be prosecuted for ignoring it.
Children 12 years and under should ride properly buck-
led up in a rear seat, if available. According to crash
statistics, children are safer when properly restrained in
the rear seats rather than in the front.

around, and insert the latch plate into the buckle
again. If you still can't make the child restraint secure,
try a different seating position.
²Buckle the child into the seat according to the child
restraint manufacturer's directions.
²When your child restraint is not in use, secure it in the
vehicle with the seat belt or remove it from the vehicle.
Do not leave it loose in the vehicle. In a sudden stop or
collision, it could strike the occupants or seat backs
and cause serious personal injury.
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 manufacturer's directions exactly when installing
an infant or child restraint.
Lower Anchors and Tether for CHildren (LATCH)
Each vehicle is equipped with the child restraint anchor-
age system called LATCH, which stands for Lower
Anchors and Tether for CHildren. LATCH child restraint
anchorage systems are installed in the Standard Cab
passenger seat position and the Quad Cab rear seat
outboard positions. LATCH equipped seating positions
feature both lower anchor bars, located at the back of the
seat cushion, and tether strap anchorages, located behind
the seatback (refer to Child Restraint Tether Anchor later
in this section).
Identification dots are located above the standard cab
front seat lower anchorages as a guide for locating lower
anchors.

Child Restraint Tether Anchor
Child restraints having tether straps and hooks for con-
nection to tether anchors have been available for some
time. In fact, many child restraint manufacturers will
provide add-on tether strap kits for their older products.
Regular Cab models of Ram Pickups have two tether
anchorages, one each behind the front center and right
seats. Quad Cab and Mega Cab models have three
anchorages, one behind each of the rear seats.WARNING!
An incorrectly anchored tether strap could lead to
seat failure and injury to the child. In a collision, the
seat could come loose and allow the child to crash
into the inside of the vehicle or other passengers, or
even be thrown from the vehicle. Use only the anchor
positions directly behind the child seat to secure a
child restraint top tether strap. Follow the instruc-
tions below. See your dealer for help if necessary.
Tether Anchorage Points at the Right and Center
Front Seat (Regular Cab - All Seats)
1.Place the child restraint on the seat and adjust the tether
strap so that it will reach over the seat back under the head
restraint to the tether anchor directly behind the seat.
2. Lift the cover (if so equipped), and attach the hook to
the square opening in the sheet metal.

CAUTION!
Do not leave your vehicle unattended with the en-
gine running as you would not be able to react to the
temperature indicator if the engine overheats.
NOTE:Engine idle speed will automatically increase to
1000 rpm at elevated coolant temperatures to improve
engine cooling.
NOTE:If the gauge pointer moves to either extreme of
the gauge, the ªCheck Gagesº indicator will illuminate
and a single chime will sound.
14. Security Light
The light will flash rapidly for approximately 16 seconds
when the vehicle theft alarm is arming. The light willflash at a slower rate after the alarm is set. The security
light will also come on for about two seconds when the
ignition is first turned ON.
15. Transmission Range Indicator (Automatic
Transmissions Only)
When the gear selector lever is moved, this indicator
shows the automatic transmission gear range selected.
16. Odometer/Trip Odometer
The odometer shows the total distance the vehicle has
been driven. U.S. federal regulations require that upon
transfer of vehicle ownership, the seller certify to the
purchaser the correct mileage that the vehicle has been
driven. Therefore, if the odometer reading is changed
during repair or replacement, be sure to keep a record of
the reading before and after the service so that the correct
mileage can be determined.

Inflation Pressure
This is the cold tire inflation pressure for your vehicle for
all loading conditions up to full GAWR.
Curb Weight
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo
loaded into the vehicle. The front and rear curb weight
values are determined by weighing your vehicle on a
commercial scale before any occupants or cargo are
added.
Loading
The actual total weight and the weight of the front and
rear of your vehicle at the ground can best be determined
by weighing it when it is loaded and ready for operation.The entire vehicle should first be weighed on a commer-
cial scale to insure that the GVWR has not been exceeded.
The weight on the front and rear of the vehicle should
then be determined separately to be sure that the load is
properly distributed over front and rear axle. Weighing
the vehicle may show that the GAWR of either the front
or rear axles has been exceeded but the total load is
within the specified GVWR. If so, weight must be shifted
from front to rear or rear to front as appropriate until the
specified weight limitations are met. Store the heavier
items down low and be sure that the weight is distributed
equally. Stow all loose items securely before driving.
Improper weight distributions can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate.
