•and the electrical wiring which connects the components
The diagnostic module monitors its own internal circuits and the
supplemental air bag electrical system wiring (including the impact
sensors), the system wiring, the air bag system readiness light, the air
bag back up power, the air bag ignitors and safety belt pretensioners.
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 to theAir bag readiness
section in theInstrument clusterchapter. Routine maintenance of the
air bag is not required.
Any difficulty with the system is indicated by one or more of the
following:
•The readiness light will either
flash or stay lit
•The readiness light will not
illuminate immediately after
ignition is turned to the RUN position
•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.
Side air bag system
Do not place objects or mount equipment on or near the air bag
cover on the side of the seatbacks of the front seats or in front
seat areas that may come into contact with a deploying air bag. Failure
to follow these instructions may increase the risk of personal injury in
the event of a collision.
Do not use accessory seat covers. The use of accessory seat
covers may prevent the deployment of the side air bags and
increase the risk of injury in an accident.

Do not lean your head on the door. The side air bag could injure
you as it deploys from the side of the seatback.
Do not attempt to service, repair, or modify the air bag SRS, its
fuses or the seat cover on a seat containing an air bag. See your
Ford or Lincoln Mercury dealer.
All occupants of the vehicle should always wear their safety belts
even when an air bag SRS is provided.
How does the side air bag system work?
The side air bag system consists of
the following:
•An inflatable nylon bag (air bag)
with a gas generator concealed
behind the outboard bolster of
the driver and front passenger
seatbacks.
•A special seat cover designed to
allow air bag deployment.
•The same warning light,
electronic control and diagnostic unit as used for the front air bags.
•Two crash sensors located under the outboard side of the front seats,
attached near the floor.
Side air bags, in combination with seat belts, can help reduce the risk of
severe injuries in the event of a significant side impact collision.
The side air bags are fitted on the outboard side of the seatbacks of the
front seats. In certain lateral collisions, the air bag on the side affected
by the collision will be inflated, even if the respective seat is not
occupied. The air bag was designed to inflate between the door panel
and occupant to further enhance the protection provided occupants in
side impact collisions.
The air bag SRS is designed to activate when the vehicle sustains lateral
deceleration sufficient to cause the sensors to close an electrical circuit
that initiates air bag inflation.
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

All occupants of the vehicle, including the driver, should always
wear their safety belts even when an inflatable curtain is
provided.
To reduce the risk of injury, do not obstruct or place objects in
the deployment of the inflatable curtain.
How does the side air curtain system work?
The design and development of the
side air curtain 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 air bags (including side air
curtain systems).
The side air curtain system consists
of the following:
•An inflatable nylon curtain with a
gas generator concealed behind
the headliner and above the
doors.
•The headliner will flex to open
above the side doors to allow air curtain deployment.
•The same warning light, electronic control and diagnostic unit as used
for the front airbags.
•Two crash sensors located under the outboard side of the front seats,
attached near the floor.
•Two crash sensors located at the base of the“C”pillars above the
wheel house.
•An inflatable nylon bag (airbag) with a gas generator concealed behind
the outboard bolster of the driver and front passenger seatbacks.
•A special seat cover to allow airbag deployment (front seats only).

Side air curtains and side air bags, in combination with seat belts, can
help reduce the risk of severe injuries in the event of a significant side
impact collision.
The side air curtains are mounted to the sheet metal above the first and
second row seats. In certain lateral collisions, the air curtain and
seat-mounted side air bag on the side affected by the collision will be
inflated, even if the respective seat is not occupied. The air curtain was
designed to inflate between the side window area and occupant to
further enhance the head protection provided to occupants in side
impact collisions. The seat-mounted side air bag was designed to inflate
between the door panel and occupant to further enhance the protection
provided occupants in side impact collision.
The side air curtain system SRS is designed to activate when the vehicle
sustains lateral deceleration sufficient to cause the sensors to close an
electrical circuit that initiates air curtain and seat-mounted side air bag
inflation.
The fact that the side air curtain and seat-mounted side air bag 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. The side air curtain system is designed to inflate in side
impact collisions, not roll-over, rear impact, frontal or near-frontal
collisions, unless the collision causes sufficient lateral deceleration.
Several air bag system components get hot after inflation. Do not
touch them after inflation.
If the side air curtain has
deployed,the air curtain
will not function again. The
side air curtain system
(including the A, B and C
pillar trim and headliner) must
be inspected and serviced by a
qualified technician in
accordance with the vehicle
service manual.If the air curtain
is not replaced, the unrepaired
area will increase the risk of injury
in a collision.

The rear park assist is automatically
enabled when the gear selector is
placed in R (Reverse) and the
ignition is ON. A park assist control
allows the driver to disable the
system only when the ignition is
ON, and the gear selector is in R
(Reverse).
The OFF indicator remains
illuminated when the system is
disabled. Press the control to
disable or enable the system. Once disabled, the system will remain
disabled until the control is pressed or until the next ignition cycle.
The indicator will remain illuminated to indicate a failure of the rear park
assist.
Always keep the sensors (located on the rear bumper/fascia) free
from snow, ice and large accumulations of dirt (do not clean the
sensors with sharp objects). These elements may cause the
system to operate inaccurately.
If the vehicle sustains damage to the rear bumper/fascia, leaving
it misaligned or bent, the sensing zone may be altered causing
inaccurate measurement of obstacles or false alarms.
DRIVING THROUGH WATER
If driving through deep or standing water is unavoidable, proceed very
slowly especially when the depth is not known. Never drive through
water that is higher than the bottom of the hubs (for trucks) or the
bottom of the wheel rims (for cars). When driving through water,
traction or brake capability may be limited. Also, water may enter your
engine’s air intake and severely damage your engine or your vehicle may
stall.Driving through deep water where the transmission vent
tube is submerged may allow water into the transmission and
cause internal transmission damage.
Once through the water, always dry the brakes by moving your
vehicle slowly while applying light pressure on the brake pedal.
Wet brakes do not stop the vehicle as quickly as dry brakes.
