2007 DODGE RAM 1500 GAS sensor

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 bags, they also need
room to inflate. Do not lean against the door or
window. Sit upright in the center of the seat.
Air Bag System Components
The airbag system consists of the following:
•Occupant Restraint Controller
•Side Remote Acceleration Sensors (If Equipped)
•Airbag Warning Light
•Driver Airbag
•Passenger Airbag
•Window Bags above Side Windows (If Equipped)
•Steering Wheel and Column
•Instrument Panel
•Interconnecting Wiring
•Knee Impact Bolsters
•Front Acceleration Sensors
50 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

•Driver and Front Passenger Seat Belt Pretensioners
•Driver Seat Track Position Sensor (If Equipped)
•Passenger Side Frontal Airbag ON/OFF Switch (Stan-
dard Cab Vehicles Only)
•Passenger Airbag Disable (PAD) Indicator Light (Stan-
dard Cab Vehicles Only)
How the Airbag System Works
•
TheOccupant Restraint Controller (ORC)determines
if a frontal collision is severe enough to require the
airbags to inflate. The front airbag inflators are de-
signed to provide different rates of airbag inflation
from direction provided by the ORC. The ORC will not
detect roll over.
The ORC 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 theitems listed above except the steering wheel and
column, and knee bolsters. If the key is in the OFF
position, in the ACC position, or not in the ignition,
the airbags are not on and will not inflate.
During a moderate-to-severe rear impact the ORC may
deploy the seat belt pretensioners alone.
Also, the ORC turns on the AIRBAG warning
light in the instrument panel for 6 to 8 seconds
for a self-check when the ignition is first turned
on. After the self-check, the AIRBAG warning
light will turn off. If the ORC detects a malfunction in any
part of the system, it turns on the AIRBAG warning light
either momentarily or continuously. A single chime will
sound if the light comes on again after initial start up.

WARNING!
Whenever an airbag is turned off, even a lap/
shoulder belted passenger may hit their head, neck,
or chest on the dashboard (instrument panel) or
windshield in a crash. This may result in serious
injury or death.
To Shut Off the Passenger Airbag (Standard Cab Ve-
hicles Only)
Place the ignition key in the Passenger Airbag On/Off
Switch, push the key in and turn clockwise, and remove
the key from the switch. This will shut off the passenger
side airbag. The “Off” light near the switch will illumi-
nate when the ignition switch is turned to the ON
position.To Turn On the Passenger Airbag (Standard Cab Ve-
hicles Only)
Place the ignition key in the Passenger Airbag On/Off
Switch, push the key in and turn counterclockwise, and
remove the key from the switch. This will turn on the
passenger airbag. The “Off” light near the switch will be
off when the ignition switch is turned to the ON position.If A Deployment Occurs
The airbag system is designed to deploy the airbags
when the impact sensors detect a moderate-to-severe
frontal collision, to help restrain the driver and front
passenger, and then immediately deflate.
NOTE:A frontal collision that is not severe enough to
need airbag protection will not activate the system. This
does not mean something is wrong with the airbag
system.

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 theOffposition, 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.
90 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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 HomeLinkUniversal Transceiver replaces up to
three remote controls (hand held transmitters) that oper-
ate 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 vehicle’s battery and charging system; no batteries
are needed.
186 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

WARNING!
Many factors, such as vehicle loading, road condi-
tions and driving conditions, influence the chance
that wheel lift or rollover may occur. ERM can not
prevent all wheel lift or rollovers, especially those
that involve leaving the roadway or striking objects
or other vehicles. Only a safe, attentive, and skillful
driver can prevent accidents. The capabilities of an
ERM-equipped vehicle must never be exploited in a
reckless or dangerous manner which could jeopar-
dize the user’s safety or the safety of others.
ESP (Electronic Stability Program)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESP cor-
rects for over/under steering of the vehicle by applyingthe brake of the appropriate wheel to assist in counter-
acting the over/under steer condition. Engine power
may also be reduced to help the vehicle maintain the
desired path.
ESP uses sensors in the vehicle to determine the vehicle
path intended by the driver and compares it to the actual
path of the vehicle. When the actual path does not match
the intended path, ESP applies the brake of the appropri-
ate wheel to assist in counteracting the oversteer or
understeer condition.
•Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
•Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
352 STARTING AND OPERATING

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 cur-
rent Dodge BODY BUILDER’S GUIDE. See your dealer,
installer or snowplow manufacture for this information.
There are unique electrical systems that must be con-
nected to properly assure operator safety and prevent
overloading vehicle systems.
