sensor Mercury Mariner 2008 s User Guide

The RCM (restraints control 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).
Several air bag system components get hot after inflation. Do not
touch them after inflation.
If the airbag has deployed,the airbag will not function again
and must be replaced immediately.If the airbag is not
replaced, the unrepaired area will increase the risk of injury in a
collision.
Front passenger sensing system
The front passenger sensing system is designed to meet the regulatory
requirements of Federal Motor Vehicle Safety Standard (FMVSS) 208
and is designed to disable (will not inflate) the front passenger’s frontal
airbag under certain conditions.
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
disabled (will not inflate).
The front passenger sensing system will disable (will not inflate) 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,
The front passenger sensing system will turn off the passenger seat side
airbag if:
•the seat is empty and safety belt is unbuckled.

Do not attempt to service, repair, or modify the airbag SRS, its
fuses or the seat cover on a seat containing an airbag. See an
authorized 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 on the lower portion of the b-pillar (one on
each side of the vehicle).
Side airbags, in combination with safety 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 airbag 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 an authorized
dealer.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 authorized dealer immediately. Unless serviced, the system may
not function properly in the event of a collision.

How does the Safety Canopy™ system 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 warning light, electronic control and diagnostic unit as used
for the front airbags.
•Two crash sensors mounted at lower B-Pillar (one on each side).
•Two crash sensors located at the c-pillar behind the rear doors (one
on each side).
•Rollover sensor in the restraints control module (RCM).
The Safety Canopy™ system, in combination with safety 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 or third 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 active when the vehicle
sustains lateral deceleration sufficient to cause the RCM to initiate Safety
Canopy™ inflation or when a certain likelihood of a rollover event is
detected by the rollover sensor.

When mounting replacement tires and wheels, you should not
exceed the maximum pressure indicated on the sidewall of the
tire to set the beads without additional precautions listed below. If the
beads do not seat at the maximum pressure indicated, re-lubricate and
try again.
When inflating the tire for mounting pressures up to 20 psi (1.38 bar)
greater than the maximum pressure on the tire sidewall, the following
precautions must be taken to protect the person mounting the tire:
1. Make sure that you have the correct tire and wheel size.
2. Lubricate the tire bead and wheel bead seat area again.
3. Stand at a minimum of 12 ft. (366 cm) away from the tire wheel
assembly.
4. Use both eye and ear protection.
For a mounting pressure more than 20 psi (1.38 bar) greater than the
maximum pressure, a Ford Dealer or other tire service professional
should do the mounting.
Always inflate steel carcass tires with a remote air fill with the person
inflating standing at a minimum of 12 ft. (366 cm) away from the tire
wheel assembly.
Important:Remember to replace the wheel valve stems when the road
tires are replaced on your vehicle.
It is recommended that the two front tires or two rear tires generally be
replaced as a pair.
The tire pressure sensors mounted in the wheels (originally installed on
your vehicle) are not designed to be used in aftermarket wheels.
The use of wheels or tires not recommended by Ford Motor Company
may affect the operation of your Tire Pressure Monitoring System.
If the TPMS indicator is flashing, your TPMS is malfunctioning. Your
replacement tire might be incompatible with your TPMS, or some
component of the TPMS may be damaged.
Safety practices
Driving habits have a great deal to do with your tire mileage and safety.
•Observe posted speed limits
•Avoid fast starts, stops and turns
•Avoid potholes and objects on the road
•Do not run over curbs or hit the tire against a curb when parking

following two conditions: (1) This device may not cause harmful
interference, and (2) This device must accept any interference received,
including interference that may cause undesired operation.
The Tire Pressure Monitoring System is NOT a substitute for
manually checking tire pressure. The tire pressure should be
checked periodically (at least monthly) using a tire gauge, see
Inflating your tiresin this chapter. Failure to properly maintain your
tire pressure could increase the risk of tire failure, loss of control,
vehicle rollover and personal injury.
Changing tires with TPMS
Each road tire is equipped with
a tire pressure sensor fastened
to the inside rim of the wheel.
The pressure sensor is covered
by the tire and is not visible
unless the tire is removed. The
pressure sensor is located
opposite (180 degrees) from the
valve stem. Care must be taken
when changing the tire to avoid
damaging the sensor.It is
recommended that you always have
your tires serviced by an authorized
dealer.
The tire pressure should be checked
periodically (at least monthly) using
an accurate tire gauge, refer to
Inflating your tiresin this chapter.
Understanding your Tire Pressure Monitoring System (TPMS)
The Tire Pressure Monitoring System measures pressure in your four
road tires and sends the tire pressure readings to your vehicle. The Low
Tire Pressure Warning Lamp will turn ON if the tire pressure is
significantly low. Once the light is illuminated, your tires are under
inflated and need to be inflated to the manufacturer’s recommended tire
pressure. Even if the light turns ON and a short time later turns OFF,
your tire pressure still needs to be checked. Visit www.checkmytires.org
for additional information.

The RSS automatically turns on
when the gear selector is placed in
R (Reverse) and the ignition is on.
An RSS control allows the driver to
turn the RSS on and off. To turn the
RSS off, the ignition must be on.
The system will remain off until
either the RSS control is pressed again or the ignition is turned off, then
on again. 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.
FOUR WHEEL DRIVE (4WD) SYSTEM (IF EQUIPPED)
For important information regarding safe operation of this type
of vehicle, seePreparing to drive your vehiclein this chapter.
Your vehicle is equipped with an intelligent 4WD System that
continuously monitors vehicle conditions and automatically adjusts the
power distribution between the front and rear wheels. It combines
transparent all-surface operation with highly capable four-wheel drive.
The 4WD system is always active and requires no driver input. It is
capable of handling all road conditions, including street and highway
driving as well as off-road and winter driving.
Driving off-road with truck and utility vehicles
4WD vehicles are specially equipped for driving on sand, snow, mud and
rough terrain and have operating characteristics that are somewhat
different from conventional vehicles, both on and off the road.
How your vehicle differs from other vehicles
Truck and utility vehicles can differ from some other vehicles. Your
vehicle may be higher to allow it to travel over rough terrain without
getting hung up or damaging underbody components.

CHANGING A FLAT TIRE
If you get a flat tire while driving:
•do not brake heavily.
•gradually decrease the vehicle’s speed.
•hold the steering wheel firmly.
•slowly move to a safe place on the side of the road.
Your vehicle may be equipped with a conventional spare tire that is
different in one or more of the following: type, brand, size, speed rating
and tread design. If this is the case, this dissimilar spare tire is still rated
for your vehicle loads (GAWR and GVWR). This temporary spare tire is
not equipped with a Tire Pressure Monitor System (TPMS) sensor.
Note:The tire pressure monitoring system (TPMS) indicator light will
illuminate when the spare is in use. To restore the full functionality of
the TPMS system, all road wheels equipped with the tire pressure
monitoring sensors must be mounted on the vehicle.
Have a flat tire serviced by an authorized dealer in order to prevent
damage to the TPMS sensor, refer toTire Pressure Monitoring System
(TPMS)in theTires, Wheels, and Loadingchapter. Replace the spare
tire with a road tire as soon as possible. During repairing or replacing of
the flat tire, have the authorized dealer inspect the TPMS sensor for
damage.
The use of tire sealants may damage your Tire Pressure
Monitoring System and should not be used.
Refer toTire Pressure Monitoring System (TPMS)in theTire,
Wheels and Loadingchapter for important information. If the
tire pressure monitor sensor becomes damaged, it will no longer
function.
