2003 FORD F150 sensor

One touch down
Allows the driver’s window to open
fully without holding the control
down. Press completely down on
AUTO and release quickly. Press
again to stop.
Accessory delay (if equipped)
With accessory delay, the window switches may be used for up to ten
minutes after the ignition switch is turned to the OFF position or until
any door is opened.
MIRRORS
Automatic dimming rear view mirrors (if equipped)
Your vehicle is equipped with an inside rear view mirror with an
auto-dimming function. The electronic day/night mirror will change from
the normal state to the non-glare state when bright lights (glare) reach
the inside rear view mirror. When the inside rear view mirror detects
bright light from behind the vehicle, the inside rear view mirror will
automatically adjust (darken) to minimize glare.
Do not block the sensor on the backside of the inside rear view mirror
since this may impair proper system performance.
Press the control to turn the mirror
OFF or AUTO.
The mirror will automatically return
to the normal state whenever the
vehicle is placed in R
(Reverse)(when the mirror is on) to ensure a bright clear view when
backing up.

Additional equipment may affect the performance of the air bag
sensors increasing the risk of injury. Please refer to the Body
Builders Layout Book for instructions about the appropriate installation
of additional equipment.
Children and air bags
For additional important safety information, read all information on
safety restraints in this guide.
Children must always be properly restrained. Failure to follow these
instructions may increase the risk of injury in a collision.
An infant in a rear-facing seat faces a high risk of serious or fatal
injuries from a deploying passenger air bag. Rear facing infant
seats should NEVER be placed in the front seats, unless the passenger
air bag is turned off. SeePassenger air bag ON/OFF switch.
How does the air bag supplemental restraint system work?
The air bag SRS is designed to
activate when the vehicle sustains
sufficient longitudinal deceleration.
The fact that the air bags did not
inflate in a collision does not mean
that something is wrong with the
system. Rather, it means the forces
were not of the type sufficient to
cause activation. Air bags are
designed to inflate in frontal and
near-frontal collisions, not rollover,
side-impact, or rear-impacts.
Seating and Safety Restraints

The air bags inflate and deflate
rapidly upon activation. After air bag
deployment, it is normal to notice a
smoke-like, powdery residue or
smell the burnt propellant. This may
consist of cornstarch, talcum
powder (to lubricate the bag) or
sodium compounds (e.g., baking
soda) that result from the
combustion process that inflates the
air bag. Small amounts of sodium
hydroxide may be present which
may irritate the skin and eyes, but
none of the residue is toxic.
While the system is designed to help
reduce serious injuries, it may also
cause minor abrasions, swelling or temporary hearing loss. Because air
bags must inflate rapidly and with considerable force, there is the risk of
death or serious injuries such as fractures, facial and eye injuries or
internal injuries, particularly to occupants who are not properly
restrained or are otherwise out of position at the time of air bag
deployment. Thus, it is extremely important that occupants be properly
restrained as far away from the air bag module as possible while
maintaining vehicle control.
Several air bag system components get hot after inflation. Do not
touch them after inflation.
If the air bag has deployed,the air bag will not function
again and must be replaced immediately.If the air bag is not
replaced, the unrepaired area will increase the risk of injury in a
collision.
The SRS consists of:
•driver and passenger air bag modules (which include the inflators and
air bags),
•one or more impact and safing sensors, passenger air bag deactivation
switch and diagnostic monitor (RCM)
•a readiness light and tone,
•and the electrical wiring which connects the components.
Seating and Safety Restraints
114

The RCM (restraints control module) monitors its own internal circuits
and the supplemental air bag electrical system warning (including the
passenger air bag deactivation switch, the impact sensors, the system
wiring, the air bag system readiness light, the air bag back up power and
the air bag ignitors).
Determining if the system is operational
The SRS uses readiness lights in the instrument cluster and the
passenger air bag deactivate switch or a tone to indicate the condition of
the system. Refer to theAir bag readinesssection in theInstrument
clusterchapter orPassenger air bag on/off switchsection in this
chapter. Routine maintenance of the air bag is not required.
A difficulty with the system is indicated by one or more of the following:
•The readiness lights will either
flash or stay lit.
•The readiness lights will not
illuminate immediately after
ignition is turned on.
•A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and/or light are repaired.
If any of these things happen, even intermittently, have the SRS serviced
at your dealership or by a qualified technician immediately. Unless
serviced, the system may not function properly in the event of a
collision.
Disposal of air bags and air bag equipped vehicles (including
pretensioners)
See your local dealership or qualified technician. Air bags MUST BE
disposed of by qualified personnel.

Removing snowplow
After removing a snowplow from the vehicle, ensure the vehicle’s front
toe alignment and front ride height are within specification (reset if
required).
Snowplowing with your air bag equipped vehicle
Your vehicle is equipped with a driver and passenger air bag
Supplemental Restraint System (SRS) The SRS is designed to activate in
certain frontal and offset frontal collisions when the vehicle sustains
sufficient longitudinal deceleration.
Careless or high speed driving while plowing snow which results in
sufficient vehicle decelerations can deploy the air bag. Such driving also
increases the risk of accidents.
All occupants of the vehicle, including the driver, should always
properly wear their safety belts, even when an air bag (SRS) is
provided.
Never remove or defeat the“tripping mechanisms”designed into the
snow removal equipment by its manufacturer. Doing so may cause
damage to the vehicle and the snow removal equipment as well as
possible air bag deployment.
Do not attempt to service, repair, or modify the Air Bag
Supplemental Restraint System or its fuses. See your Ford or
Lincoln Mercury dealer.
Additional equipment such as snowplow equipment may effect
the performance of the air bag sensors increasing the risk of
injury. Please refer to the Body Builders Layout Book for instructions
about the appropriate installation of additional equipment.
Engine temperature while plowing
When driving with a plow, your engine may run at a higher temperature
than normal because the attached snowplow blade will restrict airflow to
the radiator.
If you are driving more than 24 km (15 miles) at temperatures above
freezing, angle the plow blade either full left or full right to provide
maximum airflow to the radiator.
If you are driving less than 24 km (15 miles) at speeds up to 64 km/h
(40 mph) in cold weather, you will not need to worry about blade
position to provide maximum airflow.
