WARNING LIGHTS AND CHIMES
Standard instrument cluster
Optional instrument cluster
Warning lights and gauges can alert you to a vehicle condition that may
become serious enough to cause expensive repairs. A warning light may
illuminate when a problem exists with one of your vehicle’s functions.
Many lights will illuminate when you start your vehicle to make sure the
bulb works. If any light remains on after starting the vehicle, refer to the
respective system warning light for additional information.

WARNING:Always remember to turn on your headlamps at
dusk or during inclement weather. The Daytime Running Light
(DRL) System does not activate your tail lamps and generally may not
provide adequate lighting during these conditions. Failure to activate
your headlamps under these conditions may result in a collision.
PANEL DIMMER CONTROL
Use to adjust the brightness of the
instrument panel during headlamp
and parking lamp operation.
•Rotate the thumbwheel from left
to right to brighten the
instrument panel.
•Rotate the thumbwheel from right
to left to dim the instrument
panel.
Dome lamp control
The panel dimmer control also controls the dome lamp operation.
•Rotate the thumbwheel fully to the right, past detent, to activate the
dome lamp.
•In order to turn off the dome lamp, rotate the thumbwheel to the left.
AIMING THE HEADLAMPS
The headlamps on your vehicle are properly aimed at the assembly plant.
If your vehicle has been in an accident, the alignment of your headlamps
should be checked by your authorized dealer.
Headlamp aim adjustment (Crown Victoria only)
The headlamps are designed to be mechanically aimed, but can also be
aimed visually by doing the following:
1. Park the vehicle directly in front of a wall or screen on a level surface,
approximately 25 feet (7.6 meters) away. Check your headlamp
alignment at night or in a dark area so that you can see the headlamp
beam pattern.

To install the new bulb:
WARNING: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.
Note:If the bulb is accidentally touched, it should be cleaned with
rubbing alcohol before being used.
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 “stop.”
3. Connect the electrical connector into the rear of the plastic base until
it snaps, locking it into position.
4. Install the headlamp assembly with two retainers.
5. Install the radiator cover locking it in place with three retainers.
6. 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.
Replacing front parking/turn signal lamp bulbs
To remove the front parking/turn signal lamp bulbs:
1. Make sure headlamp switch is in the off position, then open the hood.
2. Remove the radiator cover by turning the three retainers to the unlock
position.
3. Remove two retainers and pull
headlamp assembly forward to
expose bulb.
4. Remove the bulb socket by
rotating it counterclockwise, then
pulling it out of the lamp assembly.

WARNING: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.
Note:If the bulb is accidentally touched, it should be cleaned with
rubbing alcohol before being used.
Note:The headlamp bulb should not be removed from the headlamp
until just before a replacement bulb is installed. Removing the bulb for
an extended period of time may affect headlamp bulb performance.
Contaminants may enter the headlamp where they can settle on the lens
and reflector. Never turn the headlamps on with the bulb removed.

side of the lamp assembly, then pull
the lamp assembly away from the
vehicle.

Accessory delay
With accessory delay, the power window switches and radio may be used
for up to 10 minutes after the ignition switch is turned off or until any
door is opened.
INTERIOR MIRROR
The interior rear view mirror has two pivot points on the support arm
which lets you adjust the mirror up or down and from side to side.
WARNING:Do not adjust the mirror while the vehicle is in
motion.
Automatic dimming interior rear view mirror (if equipped)
Your vehicle may be equipped with an interior rear view mirror which
has an auto-dimming function. The electronic day/night mirror will
change from the normal (high reflective) state to the non-glare
(darkened) state when bright lights (glare) reach the mirror. When the
mirror detects bright light from behind the vehicle, it will automatically
adjust (darken) to minimize glare.
The mirror will automatically return to the normal state whenever the
vehicle is placed in R (Reverse) to ensure a bright clear view when
backing up.
Do not block the sensors on the front and back of the interior
rear view mirror since this may impair proper mirror
performance.
Do not clean the housing or glass of any mirror with harsh
abrasives, fuel or other petroleum-based cleaning products.

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 theWarning lights and
chimessection 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, contact your
authorized dealer as soon as possible. Unless serviced, the system may
not function properly in the event of a collision.
Seat-mounted side airbag system
WARNING: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.
WARNING: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.
WARNING:Do not lean your head on the door. The side airbag
could injure you as it deploys from the side of the seatback.
WARNING:Do not attempt to service, repair, or modify the
airbag SRS, its fuses or the seat cover on a seat containing an
airbag. Contact your authorized dealer as soon as possible.
