1999 Mercury Grand Marquis battery

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.
Turn signal
Illuminates when the left or right turn
signal or the hazard lights are turned
on. If one or both of the indicators
stay on continuously or flash faster,
check for a burned-out turn signal
bulb. Refer toExterior bulbsin theMaintenance and carechapter.
High beams
Illuminates when the high beam
headlamps are turned on.
Charging system
Illuminates when the ignition is
turned to the ON position and the
engine is off. The light also
illuminates when the battery is not
charging properly, requiring
electrical system service.
Engine oil pressure (if equipped)
Illuminates when the oil pressure falls
below the normal range. Stop the
vehicle as soon as safely possible and
switch off the engine immediately.
Check the oil level and add oil if
needed. Refer toEngine oilin theMaintenance and Carechapter.

Instrumentation

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.

Changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to
operate the equipment.
Illuminated entry
The interior lamps illuminate when the remote entry system is used to
unlock the door(s) or sound the personal alarm.
The system automatically turns off after 25 seconds or when the ignition
is turned to the START or ACC position.
The inside lights will not turn off if:
²they have been turned on with the dimmer control or
²any door is open.
The battery saver will shut off the interior lamps 30 minutes after the
last door is closed.
Replacing the battery
The remote transmitter is powered by one coin type three-volt lithium
battery CR2032 or equivalent. Typical operating range will allow you to
be up to 10 meters (33 feet) away from your vehicle. A decrease in
operating range can be caused by:
²weather conditions
²nearby radio towers
²structures around the vehicle
²other vehicles parked next to the vehicle
To replace the battery:
1. Twist a thin coin between the two
halves of the transmitter near the
key ring. DO NOT TAKE THE
FRONT PART OF THE
TRANSMITTER APART.
2. Place the positive (+) side of new
battery in the same orientation.
Refer to the diagram inside the
transmitter unit.
3. Snap the two halves back
together.
Controls and features

Replacement of the battery willnotcause the remote transmitter to
become deprogrammed from your vehicle. The remote transmitter should
operate normally after battery replacement.
Replacing lost transmitters
Take all your vehicle's transmitters
to your dealer if service is required.
If you purchase additional
transmitters (up to four may be
programmed), perform the following
procedure:
To reprogram the transmitters
yourself, place the key in the
ignition and turn from OFF to ON
four times in rapid succession within
3 seconds. After doors lock/unlock, press any control on all transmitters
(up to four). When completed, turn the ignition to OFF.
All transmitters must be programmed at the same time.
SECURILOCKYPASSIVE ANTI-THEFT SYSTEM
Your vehicle is equipped with a coded-key anti-theft system. Only the
correct key will be able to start your vehicle. If your keys are lost or
stolen, you must take your vehicle to your dealership for key
reprogramming.
The SecuriLockypassive anti-theft system provides an advanced level of
vehicle theft protection. Your vehicle's engine can only be started with
the two special SecuriLockyelectronically coded keys provided with
your vehicle. Each time you start your vehicle, the SecuriLockykey is
read by the SecuriLockypassive anti-theft system. If the SecuriLocky
key identification code matches the code stored in the SecuriLocky
passive anti-theft system, the vehicle's engine is allowed to start. If the
SecuriLockykey identification code does not match the code stored in
the system or if a SecuriLockykey is not detected (vehicle theft
situation), the vehicle's engine will not operate.
The SecuriLockypassive anti-theft system is not compatible with
aftermarket remote start systems. Use of these systems may result in
vehicle starting problems and a loss of security protection. Large metallic
objects or devices such as the Mobil Speedpassyon the same key ring
as your SecuriLockykey may cause vehicle starting problems. These

Power distribution box
The power distribution box is located in the engine compartment. The
power distribution box contains high-current fuses that protect your
vehicle's main electrical systems from overloads.
Always disconnect the battery before servicing high current
fuses.
Always replace the cover to the Power Distribution Box before
reconnecting the battery or refilling fluid reservoirs.
If the battery has been disconnected and reconnected, refer to the
Batterysection of theMaintenance and Carechapter.

Removing the anti-theft lug nut
1. Insert the key over the locking lug nut. Make sure you hold the key
square to the lug nut. If you hold the key at an angle, you could damage
the key and the lug nut.
2. Place the lug nut wrench over the lug nut key and apply pressure on
the key with the wrench.
3.
Turn the wrench in a counterclockwise direction to remove the lug nut.
Reinstalling the anti-theft lug nut
1. Insert the key over the locking lug nut.
2. Place the lug nut wrench over the lug nut key and apply pressure on
the key with the wrench.
3. Install the lug nut.
JUMP STARTING YOUR VEHICLE
The gases around the battery can explode if exposed to flames,
sparks, or lit cigarettes. An explosion could result in injury or
vehicle damage.
Do not push start your vehicle. You could damage the catalytic
converter.
Batteries contain sulfuric acid which can burn skin, eyes, and
clothing, if contacted.
Do not attempt to push start your vehicle. Automatic
transmissions do not have push-start capability.
Preparing your vehicle
1.Use only a 12±volt supply to start your vehicle.
2. Do not disconnect the battery of the disabled vehicle as this could
damage the vehicle's electrical system.
3. Park the booster vehicle close to the hood of the disabled vehicle
making sure the two vehiclesdo nottouch. Set the parking brake on
both vehicles and stay clear of the engine cooling fan and other moving
parts.

4. Check all battery terminals and remove any excessive corrosion before
you attach the battery cables. Ensure that vent caps are tight and level.
5. Turn the heater fan on in both vehicles to protect any electrical
surges. Turn all other accessories off.
Connecting the jumper cables
1. Connect the positive (+) booster cable to the positive (+) terminal of
the discharged battery.
Note:In the illustrations,lightning boltsare used to designate the
assisting (boosting) battery.
2. Connect the other end of the positive (+) cable to the positive (+)
terminal of the assisting battery.

3. Connect the negative (-) cable to the negative (-) terminal of the
assisting battery.
4. Make the final connection of the negative (-) cable to an exposed
metal part of the stalled vehicle's engine, away from the battery and the
carburetor/fuel injection system.
The preferred locations of an exposed metal part (togroundthe circuit)
are the alternator mounting brackets or an engine liftingeye.Do not
use fuel lines, engine rocker covers or the intake manifold asgrounding
points.
Do not connect the end of the second cable to the negative (-)
terminal of the battery to be jumped. A spark may cause an
explosion of the gases that surround the battery.
5. Be sure that the cables are clear of fan blades, belts and other moving
parts of both engines.
