Mercury Grand Marquis 2005 Owner's Manuals

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.
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.
Always transport children 12 years old and under in the back
seat and always properly use appropriate child restraints.
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.
Never place your arm over the air bag module as a deploying air
bag can result in serious arm fractures or other injuries.
Ford Motor Company recommends that a certified technician
inspect all steering column assemblies in use in vehicles involved
in a collision. Failure to inspect and if necessary replace the steering
column assembly could result in severe injury or death in the event of
a collision.

Do not attempt to service, repair, or modify the steering column,
its adaptive module, or its fuses. See your Ford or
Lincoln/Mercury dealer.
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.
Do not put anything on or over the air bag module. Placing
objects on or over the air bag inflation area may cause those
objects to be propelled by the air bag into your face and torso causing
serious injury.
Do not attempt to service, repair, or modify the airbag
supplemental restraint systems or its fuses. See your Ford or
Lincoln/Mercury dealer.
The front passenger airbag is not designed to offer protection to
an occupant in the center front seating position.
Modifying or adding equipment to the front end of the vehicle
(including frame, bumper, front end body structure and tow
hooks) may affect the performance of the airbag system, increasing the
risk of injury. Do not modify the front end of the vehicle.

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.
Airbags can kill or injure a
child in a child seat.
NEVERplace 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. Driver and passenger airbags are designed to inflate in
frontal and near-frontal collisions, not rollover, side-impact, or
rear-impacts unless the collision causes sufficient longitudinal
deceleration.

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.
The SRS consists of the following items:
•Driver and passenger airbag modules (which include the inflators and
airbags)
•Front passenger sensing system
•Driver and passenger side airbags (if equipped)
•One or more impact and safing sensors
•A readiness light and tone
•A diagnostic module
•The electrical wiring which connects the components
The diagnostic module monitors its own internal circuits as well as 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.

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.
If the safety belt pretensioners deploy in an accident, they will
not function again ( belt will not extract or retract) and must be
replaced immediately. Failure to replace the retractor assemblies will
increase the risk of injury.
Front passenger sensing system
The front passenger sensing system will turn off the front passenger’s
frontal airbag under certain conditions. The driver’s airbag is not part of
the front passenger sensing system. 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,
•A smaller person, such as a child who has outgrown child restraints,
or a small adult occupies the front passenger seat.

Even with the front passenger sensing system, children 12 and
under should be properly restrained in the back seat.
When the front passenger seat is
occupied and the sensing system
has turned off the passenger’s
frontal airbag, thepassenger airbag
offorpass airbag offindicator will
light and stay lit to remind you that
the front passenger frontal airbag is off. When the front passenger seat is
not occupied (empty seat) or in the event that the front passenger
frontal airbag is enabled (may inflate), the indicator light will be unlit.
The indicator light is located on the instrument panel to the right of the
radio over the glove box.
The front passenger sensing system is designed to turn off the front
passenger’s frontal airbag when a rear facing infant seat, a forward-facing
child restraint, or a booster seat is detected. If the child restraint has
been installed and the indicator is not lit, then turn the vehicle off,
remove the child restraint from the vehicle and reinstall the restraint
following the child restraint manufacturer’s directions.
The front passenger sensing system is designed to enable (may inflate)
the right front passenger’s frontal airbag anytime the system senses that
a person of adult size is sitting properly in the front passenger seat.
When the passenger sensing system has allowed the airbags to be
enabled, the indicator will be unlit and stay unlit to remind you that the
airbag is enabled (may inflate).
If a person of adult-size is sitting in the front passenger’s seat, but the
passenger airbag offorpass airbag offindicator is lit, it could be that
the person isn’t sitting properly in the seat. If this happens, turn the
vehicle off and ask the person to place the seatback in the full upright
position, then sit upright in the seat, centered on the seat cushion, with
the person’s legs comfortably extended. Restart the vehicle and have the
person remain in this position for about two minutes. This will allow the
system to detect that person and then enable the passenger’s airbag. If
the indicator lamp remains lit even after this, then the occupant should
be advised to ride in the back seat.
After all occupants have adjusted their seats and put on safety belts, it’s
very important that they continue to sit upright, with their back against
the seatback, with their feet comfortably extended on the floor while the
vehicle is still in motion. Sitting improperly can increase the chance of

injury in a crash event. For example, if an occupant slouches, lies down,
turns sideways, sits forward, leans forward or sideways, or puts one or
both feet up, the chance of injury during a crash is greatly increased.
Sitting improperly out of position or with the seat back reclined
too far can take off weight from the seat cushion and affect the
decision of the passenger sensing system, resulting in serious injury or
death in a crash. Always sit upright against your seatback, with your
feet on the floor.
The front passenger sensing system may detect small or medium objects
placed on the seat cushion. For most objects that are in the front
passenger seat, the passenger airbag will be disabled. Even though the
passenger airbag is disabled, thepass airbag offlight may or may not
be illuminated according to the table below.

instrument cluster will stay lit. DO
NOT attempt to repair or service the system; take your vehicle
immediately to the dealer.

Any alteration/modification to the front passenger seat may
affect the performance of the front passenger sensing system.
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 toAirbag readinesssection
in theInstrument Clusterchapter. Routine maintenance of the airbag is
not required.
A 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 on.
•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 airbag system (if equipped)
Do not place objects or mount equipment on or near the airbag
cover on the side of the seatbacks of the front seats or in front
seat areas that may come into contact with a deploying airbag. 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 airbags and
increase the risk of injury in an accident.
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.
•Two crash sensors located near the 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. 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.
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 theAirbag readiness
section in theInstrument Clusterchapter. Routine maintenance of the
side airbag is not required.
A difficulty with the system is indicated by one or more of the following:
•The readiness light (same light as for front airbag system) will either
flash or stay lit.
•The readiness light will not illuminate immediately after ignition is
turned on.
•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.
