2002 Mercury Grand Marquis air condition

If the selected temperature is changed while the outside temperature is
displayed, the new temperature will be displayed for four seconds after it
is changed, then the outside temperature will return to the window.
If a manual override function is selected while the outside temperature is
displayed, the new function will be displayed for four seconds after it is
changed, then the outside temperature will return to the window along
with the override selection.
The outside temperature reading is most accurate when the vehicle is
moving. Higher readings may be obtained when the vehicle is not
moving. The readings that you get may not agree with temperatures
given on the radio due to differences in vehicle and station locations.
Operating tips
²In humid weather conditions, place the climate control system in DEF
before driving. This will reduce fogging on your windshield. Once the
windshield has been cleared, operate the climate control system as
desired.
²To reduce humidity buildup inside the vehicle in cold weather
conditions, don't drive with the climate control system in the OFF or
MAX A/C position.
²To reduce humidity buildup inside the vehicle in warm weather
conditions, don't drive with the climate control system in the OFF
position.
²Under normal weather conditions, your vehicle's climate control
system should be left in any position other than MAX A/C or OFF
when the vehicle is parked. This allows the vehicle to ªbreatheº
through the outside air inlet duct.
²Under snowy or dirty weather conditions, your vehicle's climate
control system should be left in the OFF position when the vehicle is
parked. This allows the climate control system to be free from
contamination of outside pollutants.
²If your vehicle has been parked with the windows closed during warm
weather conditions, the air conditioner will perform more efficiently in
cooling the vehicle if driven for two or three minutes with the
windows open. This will force most of the hot, stale air out of the
vehicle. Once the vehicle has been ªaired outº, operate the climate
control system as desired.

²Don't put objects under the front seat that will interfere with the
airflow to the rear seats.
²Remove any snow, ice or leaves from the air intake area at the area at
the base of the windshield.
²Do not place objects over the defroster outlets. These objects can
block airflow and reduce your ability to see through your windshield.
Avoid placing small objects on top of the instrument panel. These
objects may fall down into the defroster outlets and block airflow, in
addition to damaging the climate control system.
To aid in side window defogging/demisting in cold weather conditions:
1. Select VENT
2. Set the temperature control to full heat
3. Set the fan speed to HI
4. Direct the outer panel vents towards to side windows
To increase airflow to the outer panel vents, close the central panel
vents.
Do not place objects on top of the instrument panel, as these
objects may become projectiles in a collision or sudden stop.
REAR WINDOW DEFROSTER
The rear defroster control is located
on the instrument panel.
Press the rear defroster control to
clear the rear window of thin ice
and fog.
²A small LED will illuminate when
the rear defroster is activated.
The ignition must be in the ON position to operate the rear window
defroster.
The defroster turns off automatically after 10 minutes or when the
ignition is turned to the OFF position. To manually turn off the defroster
before 10 minutes have passed, push the control again.
Activating the rear window defroster will also activate the heated mirrors
(if equipped). For more information refer toHeated outside mirrorsin
theDriver controls chapter.

Adjusting the power seats ± seat mounted controls
Never adjust the driver's seat or seatback when the vehicle is
moving.
Always drive and ride with your seatback upright and the lap
belt snug and low across the hips.
Reclining the seatback can reduce the effectiveness of the seat's
safety belt in the event of a collision.
The power seat controls are located
on the side of the driver's seat.
Press to raise or lower the seat, or
to move the seat forward or
backward.
SAFETY RESTRAINTS
Personal Safety System
The Personal Safety System provides an improved overall level of frontal
crash protection to front seat occupants and is designed to help further
reduce the risk of air bag-related injuries. The system is able to analyze
different occupant conditions and crash severity before activating the
appropriate safety devices to help better protect a range of occupants in
a variety of frontal crash situations.
Your vehicle's Personal Safety System consists of:
²Driver and passenger dual-stage air bag supplemental restraints.
²Front safety belts with pretensioners, energy management retractors,
and safety belt usage sensors.
²Driver's seat position sensor.
²Passenger occupant classification sensor (if equipped).
²Front crash severity sensor.
Seating and Safety Restraints

²Restraints Control Module (RCM) with impact and safing sensors.
²Restraint system warning light and back-up tone.
²The electrical wiring for the air bags, crash sensor(s), safety belt
pretensioners, front safety belt usage sensors, driver seat position
sensor, passenger occupant classification sensor (if equipped), and
indicator lights.
How does the personal safety system work?
The Personal safety system can adapt the deployment strategy of your
vehicle's safety devices according to crash severity and occupant
conditions. A collection of crash and occupant sensors provides
information to the Restraints control module (RCM). During a crash, the
RCM activates the safety belt pretensioners and/or either one or both
stages of the dual-stage air bag supplemental restraints based on crash
severity and occupant conditions.
The fact that the pretensioners or air bags did not activate for both front
seat occupants in a collision does not mean that something is wrong with
the system. Rather, it means the Personal safety system determined the
accident conditions (crash severity, belt usage, etc.) were not
appropriate to activate these safety devices. Front air bags and
pretensioners are designed to activate only in frontal and near-frontal
collisions, not rollovers, side-impacts, or rear-impacts unless the collision
causes sufficient longitudinal deceleration.
Driver and passenger dual-stage air bag supplemental restraints
The dual-stage air bags offer the capability to tailor the level of air bag
inflation energy. A lower, less forceful energy level is provided for more
common, moderate-severity impacts. A higher energy level is used for
the most severe impacts. Refer toAir bag supplemental restraints
section in this chapter.
Front crash severity sensor
The front crash severity sensor enhances the ability to detect the
severity of an impact. Positioned up front, it provides valuable
information early in the crash event on the severity of the impact. This
allows your Personal safety system to distinguish between different levels
of crash severity and modify the deployment strategy of the dual-stage
air bags and safety belt pretensioners.

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 to tailor the air bag deployment and
safety belt pretensioner activation depending upon safety belt usage.
Refer toSafety beltsection in this chapter.
Front safety belt pretensioners
The safety belt pretensioners are designed to tighten the safety belts
firmly against the occupant's body during a collision. This maximizes the
effectiveness of the safety belts and helps properly position the occupant
relative to the air bag to improve protection. The safety belt
pretensioners can be either activated alone or, if the collision is of
sufficient severity, together with the air bags.
Front safety belt energy management retractors
The front 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 toSafety beltsection in this chapter.
Determining if the Personal safety system is operational
The Personal safety system uses a warning light in the instrument cluster
or a back-up tone to indicate the condition of the system. Refer to the
Warning lightsection in theInstrument clusterchapter. 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 air bag supplemental restraints, crash sensor(s),
safety belt pretensioners, front safety belt buckle sensors, driver seat
position sensor, and passenger occupant classification sensor (if
equipped). 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.
²The warning light will either flash or stay lit.
²The warning light will not illuminate immediately after ignition is
turned on.
²A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and warning light are repaired.

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.
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 toAir bag readinesssection
in theInstrument clusterchapter. Routine maintenance of the air bag is
not required.
A difficulty with the system is indicated by one or more of the following:
²The readiness light will either
flash or stay lit.
²The readiness light will not
illuminate immediately after
ignition is turned on.
²A 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.
Disposal of air bags and air bag equipped vehicles
(including pretensioners)
For disposal of air bags or air bag equipped vehicles, see your local
dealership or qualified technician. Air bags MUST BE disposed of by
qualified personnel.

Guarding against exhaust fumes
Although odorless and colorless, carbon monoxide is present in exhaust
fumes. Take precautions to avoid its dangerous effects.
If you ever smell exhaust fumes of any kind inside your vehicle,
have your dealer inspect and fix your vehicle immediately. Do
not drive if you smell exhaust fumes. These fumes are harmful and
could kill you.
Have the exhaust and body ventilation systems checked whenever:
²the vehicle is raised for service
²the sound of the exhaust system changes
²the vehicle has been damaged in a collision
WARNING:Engine exhaust, some of its constituents, and
certain vehicle components contain or emit chemicals known to
the State of California to cause cancer and birth defects or other
reproductive harm. In addition, certain fluids contained in vehicles and
certain products of component wear contain or emit chemicals known
to the State of California to cause cancer and birth defects or other
reproductive harm.
Important ventilating information
If the engine is idling while the vehicle is stopped in an open area for
long periods of time, open the windows at least 2.5 cm (one inch).
Adjust the heating or air conditioning (if equipped) to bring in fresh air.
Improve vehicle ventilation by keeping all air inlet vents clear of snow,
leaves and other debris.
BRAKES
Your service brakes are self-adjusting. Refer to the scheduled
maintenance guide for scheduled maintenance.
Occasional brake noise is normal and often does not indicate a
performance concern with the vehicle's brake system. In normal
operation, automotive brake systems may emit occasional or intermittent
squeal or groan noises when the brakes are applied. Such noises are
usually heard during the first few brake applications in the morning;
however, they may be heard at any time while braking and can be
