light LINCOLN TOWN CAR 1999 Service Manual

Do not exceed the GVWR or the GAWR specified on the Safety
Compliance Certification Label.
Do not use replacement tires with lower load carrying capacities than the
originals because they may lower the vehicle's GVWR and GAWR
limitations. Replacement tires with a higher limit than the originals do
not increase the GVWR and GAWR limitations.
The Certification Label, found on the inside pillar of the driver's door,
lists several important vehicle weight rating limitations. Before adding
any additional equipment, refer to these limitations. If you are adding
weight to the front of your vehicle, (potentially including weight added
to the cab), the weight added should not exceed the Front Axle Reserve
Capacity (FARC). Additional frontal weight may be added to the front
axle reserve capacity provided you limit your payload in other ways
(i.e. restrict the number of passengers or amount of cargo carried).
You may add equipment throughout your vehicle if the total weight
added is equal to or less than the Total Axle Reserve Capacity (TARC)
weight. You should NEVER exceed the Total Axle Reserve Capacity.
Always ensure that the weight of passengers, cargo and equipment being
carried is within the weight limitations that have been established for
your vehicle including both Gross Vehicle Weight and Front and Rear
Gross Axle Weight Rating limits. Under no circumstance should these
limitations be exceeded. Exceeding any vehicle weight rating limitation
could result in serious damage to the vehicle and/or personal injury.
The weight of your loaded trailer should not exceed 907 kg (2 000 lbs). The
GCW of your vehicle and trailer should not exceed 2 993 kg (6 600 lbs).
TRAILER TOWING
Your vehicle is classified as a light duty towing vehicle. Do not tow a
trailer until your vehicle has been driven at least 3 200 km (2 000 miles).
Towing a trailer places an additional load on your vehicle's engine,
transmission, brakes, tires and suspension. Inspect these components
carefully after towing.
Your loaded trailer should weigh no more than 907 kg (2 000 lbs.).
Do not exceed the GVWR or the GAWR specified on the Safety
Compliance Certification Label.

²Do not allow waves to break higher than 15 cm (six inches) above the
bottom edge of the rear bumper.
Exceeding these limits may allow water to enter critical vehicle
components, adversely affecting driveability, emissions, reliability and
causing internal transmission damage.
Replace the rear axle lubricant anytime the axle has been submerged in
water. Rear axle lubricant quantities are not to be checked or changed
unless a leak is suspected or repair required.
Disconnect the wiring to the trailer before backing the trailer into the
water. Reconnect the wiring to the trailer after the trailer is removed
from the water.
DRIVING THROUGH WATER
Do not drive quickly through standing water, especially if the depth is
unknown. Traction or brake capability may be limited and if the ignition
system gets wet, your engine may stall. Water may also enter your
engine's air intake and severely damage your engine.
If driving through deep or standing water is unavoidable, proceed very
slowly. Never drive through water that is higher than the bottom of the
hubs.
Once through the water, always try the brakes. Wet brakes do not stop
the vehicle as effectively as dry brakes. Drying can be improved by
moving your vehicle slowly while applying light pressure on the brake
pedal.
Driving through deep water where the transmission is submerged
may allow water into the transmission and cause internal
transmission damage.

HAZARD FLASHER
Use only in an emergency to warn traffic of vehicle breakdown,
approaching danger, etc. The hazard flashers can be operated when the
ignition is off.
²The hazard lights control is
located on top of the steering
column.
²Depress hazard lights control to
activate all hazard flashers
simultaneously.
²Depress control again to turn the
flashers off.
RESETTING THE FUEL PUMP SHUT-OFF SWITCH
After a collision, if the engine cranks but does not start, the fuel pump
shut-off switch may have been activated. The shut-off switch is a device
intended to stop the electric fuel pump when your vehicle has been
involved in a substantial jolt.
The fuel pump shut-off switch is
located on the left side of the trunk
behind the trunk liner.

SERVICE RECOMMENDATIONS
To help you service your vehicle:
²We highlight do-it-yourself items in the engine compartment for easy
location.
²We provide a Scheduled Maintenance Guide which makes tracking
routine service easy.
If your vehicle requires professional service, your dealership can provide
necessary parts and service. Check your ªWarranty Guideº to find out
which parts and services are covered.
Use only recommended fuels, lubricants, fluids and service parts
conforming to specifications. Motorcraft parts are designed and built to
provide the best performance in your vehicle.
PRECAUTIONS WHEN SERVICING YOUR VEHICLE
Be especially careful when inspecting or servicing your vehicle.
²Do not work on a hot engine.
²When the engine is running, keep loose clothing, jewelry or long hair
away from moving parts.
²Do not work on a vehicle with the engine running in an enclosed
space, unless you are sure you have enough ventilation.
²Keep all lit cigarettes, open flames and other lit material away from
the battery and all fuel related parts.
If you disconnect the battery, the engine must ªrelearnº its idle
conditions before your vehicle will drive properly, as explained in the
Batterysection in this chapter.

What you should know about fail-safe cooling
If the engine coolant supply is depleted, this feature allows the vehicle to
be driven temporarily before incremental component damage is incurred.
The ªfail-safeº distance depends on ambient temperatures, vehicle load
and terrain.
How fail-safe cooling works
If the engine begins to overheat:
²the engine coolant temperature
gauge will move to the H (hot)
area.
²the
symbol will illuminate.
²a tone will sound 3 times.
²theService Engine Soon
indicator light will illuminate.
If the engine reaches a preset over-temperature condition, the engine
will automatically switch to alternating cylinder operation. Each disabled
cylinder acts as an air pump and cools the engine.
When this occurs the vehicle will still operate, however:
²the engine power will be limited.
²the air conditioning system will be disabled.
Continued operation will increase the engine temperature:
²the
symbol will begin to flash.
²a tone will sound 5 times.
²the engine will completely shut down, causing steering and braking
effort to increase.
Once the engine temperature cools, the engine can be re-started. Take
your vehicle to a service facility as soon as possible to minimize engine
damage.

If your battery has a cover/shield, make sure it is reinstalled
after the battery has been cleaned or replaced.
For longer, trouble-free operation, keep the top of the battery clean and
dry. Also, make certain the battery cables are always tightly fastened to
the battery terminals.
If you see any corrosion on the battery or terminals, remove the cables
from the terminals and clean with a wire brush. You can neutralize the
acid with a solution of baking soda and water.
Batteries normally produce explosive gases which can cause
personal injury. Therefore, do not allow flames, sparks or lighted
substances to come near the battery. When working near the battery,
always shield your face and protect your eyes. Always provide proper
ventilation.
When lifting a plastic-cased battery, excessive pressure on the
end walls could cause acid to flow through the vent caps,
resulting in personal injury and/or damage to the vehicle or battery.
Lift the battery with a battery carrier or with your hands on opposite
corners.
Keep batteries out of reach of children. Batteries contain sulfuric
acid. Avoid contact with skin, eyes or clothing. Shield your eyes
when working near the battery to protect against possible splashing of
acid solution. In case of acid contact with skin or eyes, flush
immediately with water for a minimum of 15 minutes and get prompt
medical attention. If acid is swallowed, call a physician immediately.
Because your vehicle's engine is electronically controlled by a computer,
some control conditions are maintained by power from the battery. When
the battery is disconnected or a new battery is installed, the engine must
relearn its idle and fuel trim strategy for optimum driveability and
performance. To begin this process:
1. Set your parking brake.
2. Put the gearshift in P (Park), turn off all accessories and start the
engine.
3. Let the engine idle for at least one minute.
