Mercury Mountaineer (2010 year). Manual — part 12

WARNING: Air bags can kill or injure a child in a child seat.
NEVER place a rear-facing child seat in front of an active air

bag. If you must use a forward-facing child seat in the front seat, move
the seat all the way back.

WARNING: Always transport children 12 years old and under in
the back seat and always properly use appropriate child

restraints.

The front passenger sensing system can automatically turn off the front
passenger airbag and passenger seat-mounted side airbag. The system is
designed to help protect small (child size) occupants from frontal airbag
deployments when they are seated or restrained in the front passenger
seat contrary to proper child-seating or restraint usage
recommendations. Even with this technology, parents are STRONGLY
encouraged to always properly restrain children in a rear seating
position. The sensor also turns off the passenger front airbag and
passenger seat-mounted side airbag when the passenger seat is empty.

Front safety belt usage sensors

The front safety belt usage sensors detect whether or not the driver and
front outboard passenger safety belts are fastened. This information
allows your Personal Safety System

威 to tailor the airbag deployment and

safety belt pretensioner activation depending upon safety belt usage.

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.

Front safety belt energy management retractors

The front 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 to Energy management feature
section in this chapter.

Determining if the Personal Safety System

姞 is operational

The Personal Safety System

威 uses a warning light in the instrument

cluster or a back-up tone to indicate the condition of the system. Refer
to the Warning lights and chimes section in the Instrument Cluster
chapter. Routine maintenance of the Personal Safety System

威 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, front
passenger sensing system, and the driver seat position sensor. 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 the 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, contact your
authorized dealer as soon as possible. Unless serviced, the system may
not function properly in the event of a collision.

Safety restraints precautions

WARNING: Always drive and ride with your seatback upright
and the lap belt snug and low across the hips.

WARNING: To reduce the risk of injury, make sure children sit
in a rear seating position where they can be properly restrained.

WARNING: Never let a passenger hold a child on his or her lap
while the vehicle is moving. The passenger cannot protect the

child from injury in a collision.

WARNING: All occupants of the vehicle, including the driver,
should always properly wear their safety belts, even when an

airbag supplemental restraint system (SRS) is provided.

WARNING: It is extremely dangerous to ride in a cargo area,
inside or outside of a vehicle. In a collision, people riding in

these areas are more likely to be seriously injured or killed. Do not
allow people to ride in any area of your vehicle that is not equipped
with seats and safety belts. Be sure everyone in your vehicle is in a
seat and using a safety belt properly.

WARNING: In a rollover crash, an unbelted person is
significantly more likely to die than a person wearing a safety

belt.

WARNING: Each seating position in your vehicle has a specific
safety belt assembly which is made up of one buckle and one

tongue that are designed to be used as a pair. 1) Use the shoulder belt
on the outside shoulder only. Never wear the shoulder belt under the
arm. 2) Never swing the safety belt around your neck over the inside
shoulder. 3) Never use a single belt for more than one person.

WARNING: When possible, all children 12 years old and under
should be properly restrained in a rear seating position.

WARNING: Safety belts and seats can become hot in a vehicle
that has been closed up in sunny weather; they could burn a

small child. Check seat covers and buckles before you place a child
anywhere near them.

WARNING: Front and rear seat occupants, including pregnant
women, should wear safety belts for optimum protection in an

accident.

Energy management feature
• This vehicle has a safety belt system with an energy management

feature at the front seating positions to help further reduce the risk of
injury in the event of a head-on collision.

• This safety belt system has a retractor assembly that is designed to

extend the safety belt webbing in a controlled manner. This helps
reduce the belt force acting on the user’s chest.

WARNING: BELT AND RETRACTOR ASSEMBLY MUST BE
REPLACED if the safety belt assembly automatic locking

retractor feature or any other safety belt function is not operating
properly when checked by an authorized dealer. Failure to replace the
Belt and Retractor assembly could increase the risk of injury in
collisions.

Combination lap and shoulder belts

1. Insert the belt tongue into the proper buckle (the buckle closest to
the direction the tongue is coming from) until you hear a snap and feel it
latch. Make sure the tongue is securely fastened in the buckle.
• Front and rear seats

2. To unfasten, push the release button and remove the tongue from the
buckle.
• Front and rear seats

All safety restraints in the vehicle are combination lap and shoulder
belts. All of the passenger combination lap and shoulder belts have three
types of locking modes described below:

Vehicle sensitive mode

This is the normal retractor mode, which allows free shoulder belt length
adjustment to your movements and locking in response to vehicle
movement. For example, if the driver brakes suddenly or turns a corner
sharply, or the vehicle receives an impact of approximately 5 mph
(8 km/h) or more, the combination safety belts will lock to help reduce
forward movement of the driver and passengers.

Webbing extraction sensitive mode

The webbing sensitive locking mode locks the webbing and prevents
more belt from being pulled out if the belt is pulled out too quickly. The
belt will unlock when you stop pulling on it.

Automatic locking mode

When to use the automatic locking mode

In this mode, the shoulder belt is automatically pre-locked. The belt will
still retract to remove any slack in the shoulder belt. The automatic
locking mode is not available on the driver safety belt.

This mode should be used any time a child safety seat, except a
booster, is installed in passenger front or rear seating positions. Children
12 years old and under should be properly restrained in a rear seating
position whenever possible. Refer to Safety restraints for children or
Safety seats for children later in this chapter.

How to use the automatic locking mode
• Buckle the combination lap and

shoulder belt.

Seating and Safety Restraints

181

2010 Mountaineer (mnt)
Owners Guide (own2002), 1st Printing
USA (fus)

• Grasp the shoulder portion and

pull downward until the entire
belt is pulled out.

• Allow the belt to retract. As the belt retracts, you will hear a clicking

sound. This indicates the safety belt is now in the automatic locking
mode.

How to disengage the automatic locking mode

Unbuckle the combination lap and shoulder belt and allow it to retract
completely to disengage the automatic locking mode and activate the
vehicle sensitive mode.

WARNING: After any vehicle collision, the combination lap and
shoulder belt system at all passenger seating positions must be

checked by an authorized dealer to verify that the “automatic locking
retractor” feature for child seats is still functioning properly, in addition
to other checks for proper safety belt system function.

WARNING: BELT AND RETRACTOR ASSEMBLY MUST BE
REPLACED if the safety belt assembly “automatic locking

retractor” feature or any other safety belt function is not operating
properly. In addition, all safety belts should be checked for proper
function. Failure to replace the belt and retractor assembly could
increase the risk of injury in collisions.

Safety belt pretensioner

Your vehicle is equipped with safety belt pretensioners at the driver and
right front passenger seating positions.

The safety belt pretensioner tightens the safety belts firmly against the
occupant’s body at the start of the crash.

When the Safety Canopy

威 system, seat-mounted side airbags, and/or the

front airbags are activated, the safety belt pretensioners for the driver
and right front passenger seating positions will be activated when the
respective seatbelt is properly buckled.

WARNING: The driver and front passenger safety belt system
(including retractors, buckles and height adjusters) must be

replaced if the vehicle is involved in a collision that results in
deployment of front airbags, seat-mounted side airbags and Safety
Canopy

威, and safety belt pretensioners.

Refer to the Safety belt maintenance section in this chapter.

Front safety belt height adjustment

Your vehicle has safety belt height
adjustments at the front outboard
seating positions. Adjust the height
of the shoulder belt so the belt rests
across the middle of your shoulder.

To adjust the shoulder belt height,
squeeze and hold the buttons on the
side and slide the height adjuster up
or down. Release the buttons and
pull down on the height adjuster to
make sure it is locked in place.

WARNING: Position the safety belt height adjusters so that the
belt rests across the middle of your shoulder. Failure to adjust

the safety belt properly could reduce the effectiveness of the safety
belt and increase the risk of injury in a collision.

Second row comfort guide

The second row outboard
lap/shoulder belt is equipped with a
belt comfort guide. This guide is
attached to the quarter trim panel
and is used to adjust the comfort of
the shoulder belt for smaller
occupants in the outboard second
row seats.

To adjust the comfort guide:

1. Slip the shoulder belt into the
belt guide.

2. Slide the guide up or down along
the webbing so that the belt is
centered on the occupant’s shoulder.

WARNING: Position the safety belt comfort guide so that the
belt rests across the middle of your shoulder. Failure to adjust

the safety belt properly could reduce the effectiveness of the safety
belt and increase the risk of injury in a collision.

Safety belt extension assembly

If the safety belt is too short when fully extended, there is an 8 inch
(20 cm) safety belt extension assembly that can be added (part number
611C22). This assembly can be obtained from an authorized dealer.

Use only extensions manufactured by the same supplier as the safety
belt. Manufacturer identification is located at the end of the webbing on
the label. Also, use the safety belt extension only if the safety belt is too
short for you when fully extended.

WARNING: Do not use extensions to change the fit of the
shoulder belt across the torso.

Safety belt warning light and indicator chime

The safety belt warning light illuminates in the instrument cluster and a
chime sounds to remind the occupants to fasten their safety belts.

Belt-Minder

姞

The Belt-Minder

威 feature is a supplemental warning to the safety belt

warning function. This feature provides additional reminders by
intermittently sounding a chime and illuminating the safety belt warning
light in the instrument cluster when the driver’s and front passenger’s
safety belt is unbuckled.

The Belt-Minder

威 feature uses information from the front passenger

sensing system to determine if a front seat passenger is present and
therefore potentially in need of a warning. To avoid activating the
Belt-Minder

威 feature for objects placed in the front passenger seat,

warnings will only be given to large front seat occupants as determined
by the front passenger sensing system.

The following are reasons most often given for not wearing safety belts
(All statistics based on U.S. data):

Reasons given...

Consider...

“Crashes are rare events”

36700 crashes occur every day. The
more we drive, the more we are
exposed to “rare” events, even for
good drivers. 1 in 4 of us will be
seriously injured in a crash during
our lifetime.

“I’m not going far”

3 of 4 fatal crashes occur within 25
miles (40 km) of home.

“Belts are uncomfortable”

We design our safety belts to enhance
comfort. If you are uncomfortable -
try different positions for the safety
belt upper anchorage and seatback
which should be as upright as
possible; this can improve comfort.

“I was in a hurry”

Prime time for an accident.
Belt-Minder

威 reminds us to take a few

seconds to buckle up.

“Safety belts don’t work”

Safety belts, when used properly,
reduce risk of death to front seat
occupants by 45% in cars, and by
60% in light trucks.

“Traffic is light”

Nearly 1 of 2 deaths occur in
single-vehicle crashes, many when
no other vehicles are around.

“Belts wrinkle my clothes”

Possibly, but a serious crash can do
much more than wrinkle your clothes,
particularly if you are unbelted.

“The people I’m with don’t
wear belts”

Set the example, teen deaths occur 4
times more often in vehicles with
TWO or MORE people. Children and
younger brothers/sisters imitate
behavior they see.

Seating and Safety Restraints

187

2010 Mountaineer (mnt)
Owners Guide (own2002), 1st Printing
USA (fus)

Reasons given...

Consider...

“I have an airbag”

Airbags offer greater protection when
used with safety belts. Frontal airbags
are not designed to inflate in rear and
side crashes or rollovers.

“I’d rather be thrown clear”

Not a good idea. People who are
ejected are 40 times more likely
to DIE. Safety belts help prevent
ejection, WE CAN’T “PICK OUR
CRASH”.

WARNING: Do not sit on top of a buckled safety belt or insert a
latchplate into the buckle to avoid the Belt-Minder

威 chime. To

do so may adversely affect the performance of the vehicle’s airbag
system.

One-time disable

If at any time the driver/front passenger quickly buckles then unbuckles
the safety belt for that seating position, the Belt-Minder

威 is disabled for

the current ignition cycle. The Belt-Minder

威 feature will enable during

the same ignition cycle if the occupant buckles and remains buckled for
approximately 30 seconds. Confirmation is not given for the one time
disable.

Deactivating/activating the Belt-Minder

姞 feature

The driver and front passenger Belt-Minder

威 are

deactivated/activated independently. When deactivating/activating
one seating position, do not buckle the other position as this will
terminate the process.

Read Steps 1 - 4 thoroughly before proceeding with the
deactivation/activation programming procedure.

Note: The driver and front passenger Belt-Minder

威 features must be

disabled/enabled separately. Both cannot be disable/enabled during the
same key cycle.

The driver and front passenger Belt-Minder

威 features can be

deactivated/activated by performing the following procedure:

Before following the procedure, make sure that:
• The parking brake is set
• The gearshift is in P (Park)
• The ignition switch is in the off position
• The driver and front passenger safety belts are unbuckled

WARNING: While the design allows you to deactivate your
Belt-Minder

威, this system is designed to improve your chances of

being safely belted and surviving an accident. We recommend you
leave the Belt-Minder

威 system activated for yourself and others who

may use the vehicle. To reduce the risk of injury, do not
deactivate/activate the Belt-Minder

威 feature while driving the vehicle.

1. Turn the ignition switch to the on position. DO NOT START THE
ENGINE.

2. Wait until the safety belt warning light turns off (Approximately one
minute).
• Step 3 must be completed within 50 seconds after the safety belt

warning light turns off.

3. For the seating position being disabled, buckle then unbuckle the
safety belt nine times at a moderate speed, ending in the unbuckled
state. Step 3 must be completed within 50 seconds after the safety belt
warning light turns off.
• After Step 3, the safety belt warning light will be turned on for three

seconds.

4. Within approximately seven seconds of the light turning off, buckle
then unbuckle the safety belt.
• This will disable the Belt-Minder威 feature for that seating position if it

is currently enabled. As confirmation, the safety belt warning light will
flash four times per second for three seconds.

• This will enable the Belt-Minder威 feature for that seating position if it

is currently disabled. As confirmation, the safety belt warning light will
flash four times per second for three seconds, followed by three
seconds with the light off, then followed by the safety belt warning
light flashing four times per second for three seconds again.

AIRBAG SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

Important SRS precautions

The SRS is designed to work with
the safety belt to help protect the
driver and right front passenger
from certain upper body injuries.
Airbags DO NOT inflate slowly;
there is a risk of injury from a
deploying airbag.

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.

Seating and Safety Restraints

190

2010 Mountaineer (mnt)
Owners Guide (own2002), 1st Printing
USA (fus)

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 and non-Ford

tow hooks may effect the performance of the airbag sensors increasing
the risk of injury. Do not modify the front end of the vehicle with
anything other than authorized Ford accessories for your vehicle.

WARNING: Additional equipment may affect the performance of
the airbag sensors increasing the risk of injury.

191

2010 Mountaineer (mnt)
Owners Guide (own2002), 1st Printing

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. NEVER place 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
longitudinal 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. Front airbags are designed to activate in frontal and
near-frontal collisions, not rollover, side-impact, or rear-impacts unless
the collision causes sufficient longitudinal deceleration.
