2011 FORD ESCAPE HYBRID sensor

Front safety belt pretensioners
The safety belt pretensioners at the front outboard seating positions are
designed to tighten the safety belts firmly against the occupant’s body
during frontal collisions, and in side collisions and rollovers. This helps
increase the effectiveness of the safety belts. In frontal collisions, the
safety belt pretensioners can be activated alone or, if the collision is of
sufficient severity, together with the front airbags.
Safety belt energy management retractors
The front and rear outboard safety belt energy management retractors
allow webbing to be pulled out of the retractor in a gradual and
controlled manner in response to the occupant’s forward momentum.
This helps reduce the risk of force-related injuries to the occupant’s
chest by limiting the load on the occupant. Refer toEnergy
management featurein this chapter.
Determining if the Personal Safety System is operational
The Personal Safety System uses a warning light in the instrument
cluster or a back-up tone to indicate the condition of the system. Refer
to theWarning lights and chimessection in theInstrument Cluster
chapter. Routine maintenance of the Personal Safety System is not
required.
The restraints control module (RCM) monitors its own internal circuits
and the circuits for the airbag supplemental restraints, crash sensor(s),
safety belt pretensioners, front safety belt buckle sensors, driver seat
position sensor, and front passenger sensing system. In addition, the
RCM also monitors the restraints warning light in the instrument cluster.
A difficulty with the system is indicated by one or more of the following.
•The warning light will either flash or stay lit.
•The warning light 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 warning light are repaired.
If any of these things happen, even intermittently, have the Personal
Safety System serviced at an authorized dealer immediately. Unless
serviced, the system may not function properly in the event of a
collision.

WARNING:All occupants of the vehicle, including the driver,
should always properly wear their safety belts, even when an air
bag supplemental restraint system (SRS) is provided.
WARNING:When possible, all children 12 years old and under
should be properly restrained in a rear seating position.
WARNING:The National Highway Traffic Safety Administration
(NHTSA) recommends a minimum distance of at least 10 inches
(25 cm) between an occupant’s chest and the driver airbag module.
WARNING:Never place your arm over the airbag module as a
deploying airbag can result in serious arm fractures or other
injuries.
To properly position yourself away from the airbag:
•Move your seat to the rear as far as you can while still reaching the
pedals comfortably.
•Recline the seat slightly one or two degrees from the upright position.
WARNING:Do not put anything on or over the airbag module.
Placing objects on or over the airbag inflation area may cause
those objects to be propelled by the airbag into your face and torso
causing serious injury.
WARNING:Do not attempt to service, repair, or modify the
airbag supplemental restraint systems or its fuses. Contact your
authorized dealer as soon as possible.
WARNING:Modifications to the front end of the vehicle,
including frame, bumper, front end body structure, tow hooks
and B-pillar surrounding parts may affect the performance of the
airbag sensors increasing the risk of injury. Do not modify the front
end of the vehicle.
WARNING:Additional equipment may affect the performance of
the airbag sensors increasing the risk of injury.

Children and airbags
Children must always be properly
restrained. Accident statistics
suggest that children are safer when
properly restrained in the rear
seating positions than in the front
seating position. Failure to follow
these instructions may increase the
risk of injury in a collision.
WARNING:Airbags can kill
or injure a child in a child
seat.NEVERplace a rear-facing
child seat in front of an active
airbag. If you must use a
forward-facing child seat in the
front seat, move the seat all the
way back.
How does the airbag supplemental restraint system work?
The airbag SRS is designed to
activate when the vehicle sustains a
longitudinal deceleration sufficient
to cause the airbag sensors to close
an electrical circuit that initiates
airbag inflation. The fact that the
airbags did not inflate in a collision
does not mean that something is
wrong with the system. Rather, it
means the forces were not sufficient
enough to cause activation. Front
airbags are designed to inflate in
frontal and near-frontal collisions, not rollover, side-impact, or
rear-impacts unless the collision causes sufficient longitudinal
deceleration.

The airbags inflate and deflate
rapidly upon activation. After airbag
deployment, it is normal to notice a
smoke-like, powdery residue or
smell the burnt propellant. This may
consist of cornstarch, talcum
powder or sodium compounds which
may irritate the skin and eyes, but
none of the residue is toxic.
While the SRS is designed to help
reduce serious injuries, contact with
a deploying airbag may also cause
abrasions, swelling or temporary
hearing loss. Because airbags 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 airbag deployment. It is
extremely important that occupants be properly restrained as far away
from the airbag module as possible while maintaining vehicle control.
The SRS consists of:
•driver and passenger airbag modules (which include the inflators and
airbags).
•seat-mounted side airbags. Refer toSeat-mounted side airbag system
later in this chapter
•Safety CanopySystem. Refer toSafety CanopySystemlater in this
chapter.
•one or more impact and safing sensors.
•Safety belt pretensioners
•a readiness light and tone.
•diagnostic module.
•and the electrical wiring which connects the components.
•Front passenger sensing system. Refer toFront passenger sensing
systemlater in this chapter.
•“Passenger airbag off” or “pass airbag off” indicator lamp. Refer to
Front passenger sensing systemlater in this chapter.
The RCM (restraints control module) monitors its own internal circuits
and the supplemental airbag electrical system wiring (including the

impact sensors, the system wiring, the airbag system readiness light, the
airbag backup power and the airbag ignitors).
WARNING:Several air bag system components get hot after
inflation. Do not touch them after inflation.
WARNING:If the airbag has deployed,the airbag will not
function again and must be replaced immediately.If the
airbag is not replaced, the unrepaired area will increase the risk of
injury in a collision.
Front passenger sensing system
The front passenger sensing system is designed to meet the regulatory
requirements of Federal Motor Vehicle Safety Standard (FMVSS) 208
and is designed to disable (will not inflate) the front passenger’s frontal
airbag under certain conditions.
The front passenger sensing system works with sensors that are part of
the front passenger’s seat and safety belt. The sensors are designed to
detect the presence of a properly seated occupant and determine if the
front passenger’s frontal airbag should be enabled (may inflate) or
disabled (will not inflate).
The front passenger sensing system will disable (will not inflate) the
front passenger’s frontal airbag if:
•the front passenger seat is unoccupied, or has small/medium objects in
the front seat,
•the system determines that an infant is present in a rear-facing infant
seat that is installed according to the manufacturer’s instructions,
•the system determines that a small child is present in a forward-facing
child restraint that is installed according to the manufacturer’s
instructions,
•the system determines that a small child is present in a booster seat,
•a front passenger takes his/her weight off of the seat for a period of
time,
Note:When the passenger airbag off light is illuminated, the passenger
(seat mounted) side airbag may be disabled to avoid the risk of airbag
deployment injuries.

How does the side airbag system work?
The design and development of the
side airbag system included
recommended testing procedures
that were developed by a group of
automotive safety experts known as
the Side Airbag Technical Working
Group. These recommended testing
procedures help reduce the risk of
injuries related to the deployment of
side airbags.
The side airbag system consists of
the following:
•An inflatable bag (airbag) with a
gas generator concealed behind
the outboard bolster of the driver
and front passenger seatbacks.
•A special seat cover designed to
allow airbag deployment.
•The same warning light, electronic control and diagnostic unit as used
for the front airbags.
•Two crash sensors located on the lower portion of the b-pillar (one on
each side of the vehicle).
Side airbags, in combination with safety belts, can help reduce the risk of
severe injuries in the event of a significant side impact collision.
The side airbags are fitted on the outboard side of the seatbacks of the
front seats. In certain lateral collisions, the airbag on the side affected by
the collision will be inflated. The airbag was designed to inflate between
the door panel and occupant to further enhance the protection provided
occupants in side impact collisions.
The airbag SRS is designed to activate when the vehicle sustains lateral
deceleration sufficient to cause the sensors to close an electrical circuit
that initiates airbag inflation.
The fact that the airbags 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. Side airbags are designed
to inflate in side-impact collisions, not roll-over, rear-impact, frontal or
near-frontal collisions, unless the collision causes sufficient lateral
deceleration.

How does the Safety CanopySystem work?
The design and development of the
Safety Canopy System included
recommended testing procedures
that were developed by a group of
automotive safety experts known as
the Side Airbag Technical Working
Group. These recommended testing
procedures help reduce the risk of
injuries related to the deployment of
side airbags (including the Safety
Canopy).
The Safety Canopy System consists
of the following:
•An inflatable curtain with a gas
generator concealed behind the
headliner and above the doors
(one on each side of vehicle).
•A headliner designed to flex open
above the side doors to allow safety canopy deployment.
•The same warning light, electronic control and diagnostic unit as used
for the front airbags.
•Two crash sensors mounted at lower B-Pillar (one on each side).
•Two crash sensors located at the C-pillar behind the rear doors (one
on each side).
•Rollover sensor in the restraints control module (RCM).
The Safety Canopy System, in combination with safety belts, can help
reduce the risk of severe injuries in the event of a significant side impact
collision or rollover event.
Children 12 years old and under should always be properly restrained in
the second or third row seats. The safety canopy will not interfere with
children restrained using a properly installed child or booster seat
because it is designed to inflate downward from the headliner above the
doors along the side window opening.
Seating and Safety Restraints
155
2011 Escape Hybrid(ehv)
Owners Guide, 2nd Printing
USA(fus)

The Safety Canopy System is designed to active when the vehicle
sustains lateral deceleration sufficient to cause the RCM to initiate safety
canopy inflation or when a certain likelihood of a rollover event is
detected by the rollover sensor.
The safety canopy is mounted to roof side-rail sheet metal, behind the
headliner, above the first and second row seats. The safety canopy is
designed to inflate between the side window area and occupants to
further enhance protection provided in side impact collisions and rollover
events.
The fact that the safety canopy did not activate 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. The safety
canopy is designed to inflate in certain side impact collisions or rollover
events, not in rear impact, frontal or near-frontal collisions, unless the
collision causes sufficient lateral deceleration or rollover likelihood.
WARNING:Several Safety
Canopy System components
get hot after inflation. Do not
touch them after inflation.
WARNING:If the Safety Canopy System has deployed, the
safety canopy will not function again unless replaced. The Safety
Canopy System (including the A, B, C, and D pillar trim and headliner)
must be inspected and serviced by an authorized dealer. If the safety
canopy is not replaced, it will not function again, which will increase
the risk of injury in a future collision.
Determining if the system is operational
The SRS uses a readiness light in the instrument cluster or a tone to
indicate the condition of the system. Refer toWarning lights and
chimesin theInstrument Clusterchapter. Routine maintenance of the
side airbag is not required.
