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 (to lubricate the bag) or
sodium compounds (e.g., baking
soda) that result from the
combustion process that inflates the
airbag. 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, 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. Thus, it is extremely important that occupants be
properly restrained as far away from the airbag 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 airbag modules (which include the inflators and
airbags).
•side airbags and curtain (if equipped). Refer toSide airbag system
later in this chapter.
•one or more impact and safing sensors.
•a readiness light and tone.

•diagnostic module.
•and the electrical wiring which connects the components.
The diagnostic 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
back up power and the airbag ignitors.
Front passenger sensing system
The front passenger sensing system will turn off the front passenger’s
frontal airbag under certain conditions. For side airbag equipped
vehicles, the front passenger sensing system will turn off the passenger
seat side airbag if the seat is empty (unless for some reason the safety
belt is buckled). 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 not.
The front passenger sensing system is designed to meet the regulatory
requirements of Federal Motor Vehicle Safety Standard (FMVSS) 208
and is designed to turn off 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,
Even with the front passenger sensing system, children 12 and
under should be properly restrained in the back seat.

Do not lean your head on the door. The side airbag could injure
you as it deploys from the side of the seatback.
Do not attempt to service, repair, or modify the airbag SRS, its
fuses or the seat cover on a seat containing an airbag. See your
Ford or Lincoln Mercury dealer.
All occupants of the vehicle should always wear their safety belts
even when an airbag SRS is provided.
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 nylon 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.
•Crash sensors located on the B
and C pillars (one sensor on each
pillar on each side of the vehicle).
Side airbags, in combination with
seat 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. If the front passenger sensing system
detects an empty seat, the front passenger seat-mounted side airbag will
be deactivated. 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.
Several air bag system components get hot after inflation. Do not
touch them after inflation.
If the side airbag has
deployed,the airbag will
not function again. The side
airbag system (including the
seat) must be inspected and
serviced by a qualified
technician in accordance with
the vehicle service manual.If
the airbag is not replaced, the
unrepaired area will increase the
risk of injury in a collision.

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 nylon 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 readiness airbag light, electronic control and diagnostic unit
as used for the front airbags.
•Two crash sensors mounted on the B pillar (one on each side of the
vehicle).
•Two crash sensors located at the C pillar behind the rear doors (one
on each side of the vehicle).
•Rollover sensor in the restraints control module (RCM).
The Safety Canopy
system, in combination with seat 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 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.
The Safety Canopy
system is designed to activate when the vehicle
sustains lateral deceleration sufficient to cause the side crash sensor to
close an electrical circuit that initiates Safety Canopy
inflation or when
a certain likelihood of a rollover event is detected by the rollover sensor.

TRACTION CONTROL(IF EQUIPPED)
Your vehicle may be equipped with a Traction Control
system. This
system helps you maintain the stability and steerability of your vehicle. It
is especially useful on slippery road surfaces. The system operates by
detecting and controlling wheel spin. The system borrows many of the
electronic elements already present in the anti-lock braking system
(ABS).
Wheel-speed sensors allow excess wheel spin to be detected by the
Traction Control
portion of the ABS computer. Excess wheel spin is
controlled through engine torque reduction. This is realized via the fully
electronic engine control system. This process is very sensitive to driving
conditions and very fast acting. The wheels “search” for optimum
traction several times a second and adjustments are made accordingly.
The Traction Control
system will allow your vehicle to make better use
of available traction on slippery surfaces. The system is a driver aid
which makes your vehicle easier to handle primarily on snow and ice
covered roads.
During Traction Control
operation the engine will not “rev-up” when
you push further on the accelerator. This is normal system behavior.
If you should become stuck in deep
snow or on a very slippery road
surface, try switching the Traction
Control
system off. This may allow
excess wheel spin to “dig” the
vehicle out or enable a successful
“rocking” maneuver.
Aggressive driving in any road conditions can cause you to lose
control of your vehicle increasing the risk of severe personal
injury or property damage. The occurrence of a Traction Control

event is an indication that at least some of the tires have exceeded
their ability to grip the road; this may lead to an increased risk of loss
of vehicle control, vehicle rollover, personal injury and death. If you
experience a severe road event, SLOW DOWN.

The RSS automatically turns on
when the gear selector is placed in
R (Reverse) and the ignition is ON.
An RSS control on the instrument
panel allows the driver to turn the
RSS on and off. To turn the RSS off,
the ignition must be ON, and the gear selector in R (Reverse). An
indicator light on the control will illuminate when the system is turned
off. If the indicator light illuminates when the RSS is not turned off, it
may indicate a failure in the RSS.
Keep the RSS sensors (located on the rear bumper/fascia) free
from snow, ice and large accumulations of dirt (do not clean the
sensors with sharp objects). If the sensors are covered, it will
affect the accuracy of the RSS.
If your 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.
ALL WHEEL DRIVE (AWD) SYSTEM (IF EQUIPPED)
Your vehicle may be equipped with a full-time All Wheel Drive (AWD)
system. With the AWD option, power will be delivered to the front
wheels and distributed to the rear wheels as needed. The AWD system is
active all the time and requires no input from the operator.
All components of the AWD system are sealed for life and require no
maintenance.
If your vehicle is equipped with AWD, a spare tire of a different size
other than the tire provided should never be used. A dissimilar spare tire
size (other than the spare tire provided) or major dissimilar tire sizes
between the front and rear axles could cause the AWD system to stop
functioning and default to front wheel drive.
Note:Your AWD vehicle is not intended for off-road use. The AWD
feature gives your vehicle some limited off-road capabilities in which
driving surfaces are relatively level, obstruction-free and otherwise
similar to normal on-road driving conditions. Operating your vehicle
under other than those conditions could subject the vehicle to excessive
stress which might result in damage which is not covered under your
warranty.
Driving off-highway with AWD vehicles
AWD vehicles are specially equipped for driving on sand, snow, mud and
rough roads and have operating characteristics that are somewhat
different from conventional vehicles, both on and off the highway.
