2008 Mercury Mountaineer Owner's Manuals

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, 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, 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.
Safety restraints precautions
Always drive and ride with your seatback upright and the lap
belt snug and low across the hips.
To reduce the risk of injury, make sure children sit in the back
seat where they can be properly restrained.
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.
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.

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.
In a rollover crash, an unbelted person is significantly more likely
to die than a person wearing a safety belt.
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.
Always transport children 12 years old and under in the back
seat and always properly use appropriate child restraints.
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.
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.
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 two
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.

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 usedany timea 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 the rear seat
whenever possible. Refer toSafety restraints for childrenorSafety
seats for childrenlater in this chapter.
How to use the automatic locking mode
•Buckle the combination lap and
shoulder belt.
•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.
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.
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™ 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.
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™, and safety
belt pretensioners.
Refer to theSafety belt maintenancesection 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.
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.
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 a 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.
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.
Conditions of operation
If... Then...
The driver’s safety belt is not
buckled before the ignition
switch is turned to the ON
position...The safety belt warning light
illuminates 1-2 minutes and the
warning chime sounds 4-8 seconds.
The driver’s safety belt is
buckled while the indicator
light is illuminated and the
warning chime is sounding...The safety belt warning light and
warning chime turn off.
The driver’s safety belt is
buckled before the ignition
switch is turned to the ON
position...The safety belt warning light and
indicator chime remain off.
Belt-Minder
The Belt-Minder
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
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
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.
Both the driver’s and passenger’s safety belt usages are monitored and
either may activate the Belt-Minder
feature. The warnings are the same
for the driver and the front passenger. If the Belt-Minder
warnings have
expired (warnings for approximately 5 minutes) for one occupant (driver
or front passenger), the other occupant can still activate the
Belt-Minder
feature.
