If the driver safety belt is buckled while the warning indicator is illuminated and the reminder
chime is sounding, then the safety belt warning indicator and reminder chime turn off.
z If the driver safety belt is buckled before the ignition switch is turned to ON, then the safety belt
warning light will turn on for 3 seconds and then off. The indicator chime will remain off.
Belt Minder (if equipped)
The Belt Minder feature is a supplemental warning to the safety belt warning function. This feature
provides additional reminders to the driver that the driver's safety belt is unbuckled by intermittently
sounding a chime and illuminating the safety belt warning lamp in the instrument cluster.
Safety Belt Extension
A safety belt that is too short even when fully extended can be lengthened. The safety belt extension
(611C22) is available. This assembly will add approximately 20 cm (8 inches) to the length of the
safety belt. Use the safety belt extension only if the safety belt is too short when fully extended. Do not
use the safety belt extension to alter the fit of the shoulder belt across the torso. Safety belt extensions
are available at no cost from any authorized Ford or Lincoln- Mercury dealer.
Lower Anchors and Tethers for Children (LATCH)
The lower anchors and tethers for children (LATCH) system is a standarized and uniform attachment
system for installing child safety seats in passenger vehicles. LATCH- equipped child safety seats have
two lower attachments that connect to the vehicle portion of the LATCH system.
The vehicle portion of the system consists of two attachment points (6- mm wires) bolted to the floor
pan at both second row outboard seating positions. The attachment points protrude from the biteline
between the seat cushion and seat backrest.
If a child safety seat was in use during a collision, inspect the vehicle portion of the system for
damage. If any of the attachment points (6- mm wires) are damaged, a new one must be installed. See
the appropriate removal and installation procedure in this section for service.
Attaching Safety Seats with Tether Straps
Some manufacturers make child safety seats that include a tether strap that goes over the back of the
vehicle seat and attaches to an anchoring point. Other manufacturers offer the tether strap as an
accessory. Contact the manufacturer of the child safety seat for information about ordering a tether
strap. If... Then...

Functional Test III (System Road Test Inspection)
1. NOTE: If the RH or the rear safety belts are to be tested, the assistance of a passenger is
required.
Fasten the safety belts and proceed to a safe area.
2. Attain a speed of 8 km/h (5 mph).
3. WARNING: The driver and passenger must be prepared to brace themselves if the
retractor does not lock.
Test the safety belts. 1. Grasp the shoulder harness and prepare to lean forward.
2. WARNING: The maximum brake application should be on dry concrete or
equivalent hard surface, NEVER on wet pavement or gravel.
WARNING: The driver and passenger must be prepared to brace themselves
in the event the retractor does not lock.
Make a maximum brake application without a skid.
3. NOTE: Do not jerk on the safety belt webbing when carrying out this test. Lean forward slightly when the brake application is made.
4. The safety belts should lock up with minimum webbing extension.
5. If there is a lockup of both shoulder straps, the safety belt assemblies are functioning correctly. Should either or both retractors fail to lock up at the 8 km/h (5 mph) speed, repeat the test at a
constant 24 km/h (15 mph) speed. (This test must be carried out with the assistance of a RH
front or rear passenger if the RH front or rear safety belts are to be tested).
6. CAUTION: Before installing a new safety belt assembly, inspect the mounting area
for damage and distortion. If the retractor of a new safety belt assembly has been bolted
into a damaged or distorted mounting area, the retractor could be warped and may not
function. If this is the case, remove the retractor and return the sheet metal to the
original configuration and install another complete safety belt assembly.
If the retractors do not lock up at the 24 km/h (15 mph) test, return the vehicle for service of
malfunctioning safety belts.
Functional Test IV (Automatic Locking Retractor) WARNING: After any vehicle collision, the safety belt system at all outboard seating
positions (except driver, which has no "automatic locking retractor" feature) must be checked
by a qualified technician to verify that the "automatic locking" feature for child seats is still
functioning correctly, in addition to other checks for correct safety belt system function. A new
safety belt and retractor assembly must be installed if the safety belt assembly's "automatic
locking retractor" feature or any other safety belt function is not operating correctly when
checked according to the procedures in the workshop manual. Failure to install a new safety
belt and retractor assembly could increase the risk of injury in collisions.

Most air bag supplemental restraint system (SRS) diagnostic procedures will require the use of the
deactivation and reactivation procedures in this section.
The deactivation and reactivation require the installation and removal of restraint system diagnostic
tools. These procedures require removal of driver air bag module, and the disconnection of the
passenger air bag module. This reduces the risk of deployment of air bag modules and safety belt
pretensioners while diagnostics are being carried out.
Restraint system diagnostic tools are required to carry out diagnosis and testing of the supplemental
restraint system (SRS). It is not acceptable to short-circuit the air bag module connections with a
jumper wire. If a jumper wire is used to short- circuit the air bag module connections, a lamp fault code
(LFC) will be displayed.
WARNING: The restraint system diagnostic tool is for restraint system service only.
Remove from vehicle prior to road use. Failure to remove could result in injury and possible
violation of vehicle safety standards.
The reactivation procedure requires the removal of any restraint system diagnostic tools installed and
the reconnection of any air bag modules disconnected.
Deactivation Procedure
WARNING: If the supplemental restraint system (SRS) is being serviced, the system must
be deactivated and restraint system diagnostic tools must be installed. Refer to Air Bag Supplemental Restraint System (SRS) in this section.
The air bag restraint system diagnostic tools must be removed and the air bag modules
reconnected when the system is reactivated to avoid non- deployment in a collision, resulting in
possible personal injury.
NOTE: Diagnostics or repairs are not to be performed on a seat equipped with a seat side air bag with
the seat in the vehicle. Prior to attempting to diagnose or repair a seat concern when equipped with a
seat side air bag, the seat must be removed from the vehicle and the restraint system diagnostic tools
must be installed in the seat side air bag electrical connectors. The restraint system diagnostic
tools must be removed prior to operating the vehicle over the road.
NOTE: After diagnosing or repairing an SRS, the restraint system diagnostic tools must be
removed before operating the vehicle over the road.
NOTE: After diagnosing or repairing a seat system, the restraint system diagnostic tools must be
