1999 Mercury Grand Marquis ignition

²Optional instrument cluster
This gauge indicates the temperature of the engine coolant, not the
coolant level. If the coolant is not at its proper level the gauge indication
will not be accurate. If the gauge enters the red section, the engine
coolant andCheck Engine/Service Engine Soonindicators illuminate,
refer toWhat you should know about fail-safe coolingin the
Maintenance and care chapter.
Battery voltage gauge (if equipped)
This gauge shows the battery
voltage when the ignition is in the
ON position. If the pointer moves
and stays outside the normal
operating range (as indicated), have
the vehicle's electrical system
checked as soon as possible.
Engine oil pressure gauge (if equipped)
This shows the engine oil pressure
in the system. Sufficient pressure
exists as long as the needle remains
in the normal range (the area
between the ªHº and ªLº).
If the gauge indicates low pressure,
stop the vehicle as soon as safely
possible and switch off the engine
immediately. Check the oil level.

dealership or by a qualified technician.
ELECTRONIC MESSAGE CENTER
The electronic message center only
works when the ignition is in the
ON position.
The message center allows you to:
²see problems such as door ajar,
air suspension, trunk ajar, washer
fluid low
²see how many kilometers/miles
you can drive before running out
of fuel
²see when overdrive has been deactivated
²monitor the average fuel economy
²check the distance traveled during a trip on either Trip A or Trip B
²monitor the average speed

Remember to turn the ignition OFF when refueling your vehicle.
Otherwise, the display will not show the addition of fuel for a few miles.
At least 9.5 liters (2.5 gallons) of fuel must be added for the fuel gauge
to immediately show the new fuel level.
The DTE function will flash for 5 seconds and sound a tone for 1 second
when you have approximately:
²80 km (50 miles) left before you run out of fuel
²40 km (25 miles)
²16 km (10 miles)
The message center will remain in
the DTE function until the SELECT
control is pressed to change
functions.
Displayed DTE will not be equal to
AVG ECON multiplied by the FUEL
REMAIN value. DTE is calculated
using a method that considers the
fuel economy of the last 800 km
(500 miles) driven.
If ªCOº or ªCSº is displayed, there is a problem with the fuel indication
system and you should contact your dealer for service as soon as
possible.
AVG ECON (average fuel economy)
Select this function to display your
average fuel economy in liters/
100 km or miles/gallon.
If you calculate your average fuel
economy by dividing miles traveled by gallons used, your figure may be
different than displayed for the following reasons:
²your vehicle was not perfectly level during fill-up
²differences in the automatic shut-off points on the fuel pumps at
service stations
²variations in top-off procedure from one fill-up to another
²rounding of the displayed values to the nearest 0.1 liter (gallons)

Message center indicator lights
Check air suspension
Briefly illuminates when the ignition
is turned ON. This light will remain
on to indicate that the air
suspension switch is off or to
indicate a possible system fault. For
more information on the air
suspension system, refer to the
Drivingchapter.
Overdrive off
Illuminates when the transmission
control switch (TCS) has been
pushed. When the light is on, the
transmission does not shift into
overdrive. If the light does not come
on when the TCS is depressed or if
the light flashes when you are
driving, have your vehicle serviced.
Door ajar
Illuminates when one of the doors is
not completely shut and the ignition
is turned to ON. With the ignition
ON, this light will flash five times
and sound a tone for one second,
then remain on (if a door is open).
Low washer fluid
Momentarily illuminates when the
ignition is turned to ON and will
stay on when the windshield washer
fluid is low.

Trunk ajar
If the trunk is not completely
closed, this light comes on when
you turn the ignition to ON. With
the ignition ON, this light will flash
five times and sound a tone for one
second, then remain on (if the trunk
is open).
INDICATOR LAMP MODULE
The indicator lamp module contains the following lamps:
Traction ControlYactive (if equipped)
Flashes when the Traction Controly
system begins applying and
releasing the brakes and adjusting
the engine characteristics to limit a
wheelspin condition. It will be lit for
a minimum of four seconds or for
the duration of the Traction
Controlyevent.
If the Traction Controlyindicator
comes on or stays lit, either:
²the Traction Controlysystem needs service, or
²the customer has disabled the system using the traction control
switch.
For more information, refer to theDrivingchapter.
Anti-lock brake system (ABS) (If equipped)
Momentarily illuminates when the
ignition is turned on and the engine
is off. If the light does not illuminate
momentarily at start up, remains on
or continues to flash, the ABS needs
to be serviced. With the ABS light on, the anti-lock brake system is
disabled and normal braking is still effective unless the brake warning
light also remains illuminated with parking brake released.CHECK

Brake system warning
Momentarily illuminates when the
ignition is turned to the ON position
and the engine is off. If brake
warning lamp does not illuminate at
this time, seek service immediately.
Also illuminates when the parking brake is engaged. Illumination after
releasing the parking brake indicates low brake fluid level and the brake
system should be inspected immediately.

Autolamp control (if equipped)
The autolamp system provides light
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.
Daytime running lamps (DRL) (if equipped)
Turns the highbeam headlamps on with a reduced output. To activate:
²the key must be in the ON position,
²the parking brake released, and
²the headlamp control is in the OFF or Parking lamps position.
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.
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.
²The 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 ten minutes have passed, push the control again.
CLIMATE CONTROL SYSTEM
Manual heating and air conditioning system (if equipped)
Fan speed control
Controls the volume of air circulated
in the vehicle.
Temperature control knob
Controls the temperature of the
airflow inside the vehicle.
Mode selector control
Controls the direction of the airflow
to the inside of the vehicle.
The air conditioning compressor will operate in all modes except VENT
and FLR. However, the air conditioning will only function if the outside
temperature is about 10ÉC (50ÉF) or above.
Since the air conditioner removes considerable moisture from the air
during operation, it is normal if clear water drips on the ground under
the air conditioner drain while the system is working and even after you
have stopped the vehicle.
