2007 DODGE RAM 2500 DIESEL run flat

The Window Airbag System, on vehicles equipped,
consists of the following:
•AIRBAG Readiness Light (shared with the front airbag
system)
•Window Bags Above the Side Windows.
•Airbag Control Module (shared with the front airbag
system)
•Side impact sensors
•Interconnecting Wiring
How The Airbag System Works
•
The airbag control module determines if a frontal
collision is severe enough to require the airbags to
inflate.
•The airbag control module will not detect roll over, or
rear collisions.
•The airbag control module also monitors the readiness
of the electronic parts of the system whenever the
ignition switch is in the START or RUN positions.
These include all of the items listed above except the
knee bolsters, the instrument panel, and the steering
wheel and column. If the key is in the Offposition, in
the ACC position or not in the ignition, the airbags are
not on and will not inflate
•The airbag control module also turns on the AIR BAG
light in the instrument panel for 6 to 8 seconds when
the ignition is first turned on, then turns the light off.
•If it detects a malfunction in any part of the
system, it turns on the light either momen-
tarily or continuously. The instrument clus-
ter will flash the seat belt indicator if it
detects a fault with the airbag indicator.

Window Airbags Supplemental Restraint System
(SRS)—If Equipped
The window airbag control module determines if a side
collision is severe enough to require the side airbags to
inflate. The window airbag control module will not
detect roll over, front or rear collisions.
The airbag control module monitors the readiness of the
electronic parts of the system whenever the ignition
switch is in the STARTorRUN positions. These
include all of the items listed above. The airbag control
module also turns on the AIRBAG light in the instrument
panel for 6 to 8 seconds when the ignition is first turned
on as a diagnostic or system check, then turns the light
off. If it detects a malfunction in any part of the system,
it turns on the light either momentarily or continuously.
The side (window) impact SRS Airbags are designed to
activate only in certain side collisions. When the airbag
control module detects a collision requiring the window bags to inflate, it signals the inflators on the crash side of
the vehicle. A quantity of nontoxic gas is generated to
inflate the window bag. The inflating window bag
pushes the side pillar molding out of the way and covers
the window. The airbag inflates in about 30 milliseconds
(about one-quarter of the time it takes to blink your eyes)
with enough force to injure you if you are not belted and
seated properly, or if items are positioned in the area
where the window bag inflates. This especially applies to
children. The window bag is only about 3
12inches (8.9
cm) thick when it is inflated.
Enhanced Accident Response System
If the airbags deploy after an impact and the electrical
system remains functional, vehicles equipped with
power door locks will unlock automatically. In addition,
approximately 10 seconds after the vehicle has stopped
moving, the interior lights will light until the ignition
switch is turned off.
54 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
On vehicles equipped with a limited-slip differen-
tial, never run the engine with one rear wheel off the
ground, since the vehicle may drive through the rear
wheel remaining on the ground. You could lose
control of the vehicle.
Care should be taken to avoid sudden accelerations when
both rear wheels are on a slippery surface. This could
cause both rear wheels to spin, and allow the vehicle to
slide sideways on the crowned surface of a road or in a
turn.
DRIVING ON SLIPPERY SURFACES
When driving on wet or slushy roads, it is possible for a
wedge of water to build up between the tire and road
surface. This is known as hydroplaning and may cause
partial or complete loss of vehicle control and stopping
ability. To reduce this possibility, the following precau-
tions should be observed:
1. Slow down during rainstorms or when roads are
slushy.
2. Slow down if road has standing water or puddles.
3. Replace tires when tread wear indicators first become
visible.
4. Keep tires properly inflated.
5. Maintain sufficient distance between your vehicle and
the car in front to avoid a collision in a sudden stop.
288 STARTING AND OPERATING

CAUTION!
3500 Dual Rear Tires have only one approved direc-
tion of rotation. This is to accommodate the asym-
metrical design (tread pattern) of the ON/OFF road
tire and the use of Outline White Letter (OWL) tires.
•When replacing a flat, the spare tire may have to
be remounted on the rim or installed at a different
location to maintain the correct placement of the
tire on the wheel relative to the tire/wheel posi-
tion on the truck. For example, if the spare is used
to replace an outer rear tire it will have to be
remounted on the rim so that the wheel is dished
inward. That way the tread design of asymmetri-
cal tires and the white writing of the OWL tires
will maintain proper position.
ENGINE RUNAWAY
WARNING!
In case of engine runaway due to flammable fumes
from gasoline spills or turbocharger oil leaks being
sucked into the engine do the following to help
avoid personal injury and/or vehicle damage:
1. Shut off engine ignition switch.
2. Using a CO
2or dry chemical type fire extin-
guisher, direct the spray from the fire extinguisher
into the grille on the passenger side so that the spray
enters the engine air intake.
The inlet for the engine air intake is located behind the
passenger side headlamp and receives air through the
grille
