2004 DODGE RAM 1500 GAS sensor

Airbag System Components
The airbag system consists of the following:
²Airbag Control Module
²AIRBAG Readiness Light
²Driver Airbag
²Passenger Airbag
²Steering Wheel and Column
²Instrument Panel
²Crash Sensor
²Interconnecting Wiring
²Knee Impact Bolsters
²Passenger Side Frontal Airbag ON/OFF Switch (Stan-
dard Cab Vehicles Only)The Window Airbag System, on vehicles equipped,
consists of the following:
²AIRBAG Readiness Light (shared with the front airbag
system)
²Window Bags Above the Side Windows.
²Airbag Control Module (shared with the front airbag
system)
²Side impact sensors
²Interconnecting Wiring
How The Airbag System Works
²
The airbag control module determines if a frontal
collision is severe enough to require the airbags to
inflate.
²The airbag control module will not detect roll over, or
rear collisions.
48 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

To set the variance: Turn the ignition ON and set the
display to ªCompass/Temperature.º Press the RESET
button approximately five seconds. The last variance
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.

Automatic Transmission Oil Temperature Warning
Light
All vehicles with automatic transmissions are equipped
with a transmission sump oil temperature sensor and
warning light. If elevated transmission temperatures are
encountered, the engine controller will select the most
desirable gear until the transmission temperatures are
reduced. If transmission oil temperatures continue to
rise, a warning light located in the instrument cluster will
illuminate. If this should occur, stop the vehicle, shift to
Neutral, and run the engine at idle or faster until the light
goes off.
Towing With An Automatic Transmission
Vehicles equipped with an automatic transmission may
shift into and out of Overdrive, or a lower gear, when
driving in hilly areas, when heavily loaded, or when
towing into heavy winds.
When this condition occurs, select TOW/HAUL mode or
shift into a lower gear to prevent excessive transmission
wear and/or overheating, and to provide better engine
braking.
NOTE:Do not exceed the following RPM while manu-
ally downshifting:
²5800 rpm with 3.7L engines.
²5800 rpm with 4.7L engines.
²5600 rpm with 5.7L engines.

If your vehicle has an automatic transmission and you
tow a trailer frequently, change transmission fluid and
filter every 30,000 miles (48 000 km)
SNOWPLOW
Snowplow Prep Packages are available as a factory
installed option. These packages include components
necessary to equip your vehicle with a snowplow.
Dodge Ram 1500 Models
NOTE:Do not use Dodge Ram 1500 Models for snow-
plow applications.
WARNING!
On 1500 Models, snowplows, winches, and other
aftermarket equipment should not be added to the
front end of your vehicle. The airbag crash sensors
may be affected by the change in the front end
structure. The airbags could deploy unexpectedly or
could fail to deploy during a collision resulting in
serious injury or death.
CAUTION!
Using 1500 Model vehicles for snowplow applica-
tions can cause damage to the vehicle.
NOTE:Before installation of a snowplow it is highly
recommended that the owner / installer obtain and
follow the recommendations contained within the Dodge
280 STARTING AND OPERATING

conditions permit. Do not exceed 40 mph (64 km/h). The
operator should always maintain a safe stopping distance
and allow adequate passing clearance.
Methods For Removing SnowOperating Tips
Under ideal snow plowing conditions, 20 mph (32 km/h)
should be maximum operating speed. The operator
should be familiar with the area and surface to be
cleaned. Reduce speed and use extreme caution when
plowing unfamiliar areas or under poor visibility.
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.

2. Remove the three (3) bolts from the headlight housing.
NOTE:The lower bolt on the driver side headlight also
retains the ambient temperature sensor between the
headlight assembly and the frame.
