2002 Mercury Grand Marquis Owner's Manuals

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.

sensitive automatic on-off control of
the exterior lights normally
controlled by the headlamp control.
The autolamp system also keeps the
lights on for a preselected period of
time after the ignition switch is
turned to OFF.
²To turn autolamps on, rotate the
control counterclockwise. The preselected time lapse is adjustable up
to approximately three minutes by continuing to rotate the control
counterclockwise.
²To turn autolamps off, rotate the control clockwise to OFF.

Using the right bulbs
Replacement bulbs are specified in the chart below. Headlamp bulbs
must be marked with an authorized ªD.O.T.º for North America and an

and safe visibility. The correct bulbs will not damage the lamp assembly
or void the lamp assembly warranty and will provide quality bulb burn

3. Disconnect the electrical
connector from the bulb by pulling
rearward.
4. Remove the bulb retaining ring by
rotating it counterclockwise (when
viewed from the rear) to free it
from the bulb socket, and slide the
ring off the plastic base. Keep the
ring to retain the new bulb.
5. Without turning, remove the old
bulb from the lamp assembly by
gently pulling it straight back out of
the lamp assembly.
To install the new bulb:
Handle a halogen headlamp bulb carefully and keep out of
children's reach. Grasp the bulb only by its plastic base and do
not touch the glass. The oil from your hand could cause the bulb to
break the next time the headlamps are operated.
1. With the flat side of the new bulb's plastic base facing upward, insert
the glass end of the bulb into the lamp assembly. Turn the bulb left or
right to align the grooves in the plastic base with the tabs in the lamp
assembly. When the grooves are aligned, push the bulb into the lamp
assembly until the plastic base contacts the rear of the lamp assembly.
2. Install the bulb retaining ring over the plastic base until it contacts the
rear of the socket by rotating it clockwise until you feel a ªstop.º
3. Connect the electrical connector into the rear of the plastic base until
it snaps, locking it into position.
4. Install the protective cover over headlamps locking it in place with
three knobs.
5. Turn the headlamps on and make sure they work properly. If the
headlamp was correctly aligned before you changed the bulb, you should
not need to align it again.
