WARNING!
•Relying on the airbags alone could lead to more
severe injuries in a collision. The airbags work
with your seat belt to restrain you properly. In
some collisions the airbags won’t deploy at all.
Always wear your seat belts even though you
have airbags.
•Being too close to the steering wheel or instru-
ment panel during airbag deployment could cause
serious injury. Airbags need room to inflate. Sit
back, comfortably extending your arms to reach
the steering wheel or instrument panel.
•If the vehicle has window airbags, they also need
room to inflate. Do not lean against the door or
window. Sit upright in the center of the seat.
Airbag System Components
The airbag system consists of the following:
•Airbag Control Module
•AIRBAG Readiness Light
•Driver Airbag
•Passenger Airbag
•Steering Wheel and Column
•Instrument Panel
•Crash Sensor
•Interconnecting Wiring
•Knee Impact Bolsters
•Passenger Side Frontal Airbag ON/OFF Switch (Stan-
dard Cab Vehicles Only)
48 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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.

NOTE:The default for the compass variance is zone 8.
To set the variance: Turn the ignition ON and set the
display to “Compass/Temperature.” Press and hold the
RESET button approximately five seconds. The last vari-
ance zone number will be displayed. Press the STEP
button to select the new variance zone and press the
RESET button to resume normal operation.
Outside Temperature
Because the ambient temperature sensor is located un-
derhood, engine temperature can influence the displayed
temperature, therefore, temperature readings are slowly
updated when the vehicle speed is below 20 mph (30
km/h) or during stop and go driving.
GARAGE DOOR OPENER — IF EQUIPPED
The HomeLink Universal Transceiver replaces up to
three remote controls (hand held transmitters) that operate
devices such as garage door openers, motorized gates, or
home lighting. It triggers these devices at the push of a
button. The Universal Transceiver operates off your vehi-
cle’s battery and charging system; no batteries are needed.

NOTE:During snowplow usage on vehicles equipped
with an overhead console module, the outside tempera-
ture display will show higher temperatures than the
outside ambient temperature. The higher displayed tem-
perature is due to blocked or reduced airflow to the
underhood ambient temperature sensor by the snow-
plow. This is common and outside temperature display
operation will return to normal when the snowplow is
removed.
General Maintenance
Snowplows should be maintained in accordance with the
plow manufacturer’s instructions.
Keep all snowplow electrical connections and battery
terminals clean and free of corrosion. When plowing snow, to avoid transmission and driv-
etrain damage, the following precautions should be ob-
served.
•Operate with transfer case in 4L when plowing small
or congested areas where speeds are not likely to
exceed 15 mph (24 km/h). At higher speeds operate in
4H.
•Vehicles with 48RE transmissions should use 4L range
when plowing deep or heavy snow for extended
periods of time to avoid transmission overheating.
•Do not shift the transmission unless the engine has
returned to idle and wheels have stopped. Make a
practice of stepping on the brake pedal before shifting
the transmission.
344 STARTING AND OPERATING

Disposing Of Used Engine Oil And Filter
Care should be taken in disposing of the used engine
fluids from your vehicle. Used fluids, indiscriminately
discarded, can present a problem to the environment.
Contact your local dealer, service station, or governmen-
tal agency for advice on recycling programs and where
used fluids and filters can be safely discarded in your
area.
Drive Belt
Inspection
Check the belt for intersecting cracks.
•Transverse (across the belt width) cracks are accept-
able.
•Longitudinal (direction of belt length) cracks that
intersect with transverse cracks are NOT acceptable.
Replace the belt if it has unacceptable cracks, is frayed or
has pieces of material missing. The engine speed sensor, located near the damper, should
be inspected for damage if a belt is frayed.
Engine Air Cleaner Filter
CAUTION!
All air entering the engine intake must be filtered.
The abrasive particles in unfiltered air will cause
rapid wear to engine components.
The air filter housing on your Diesel Ram is equipped
with a Filter Minder™. This is an air flow restriction
gauge that will indicate when the filter element needs to
be replaced.
