ignition LINCOLN TOWN CAR 1999 Service Manual

The air suspension shut-off switch is
located on the left side of the trunk.
If this switch is in the OFF position,
the rear air suspension will not
operate.
On vehicles equipped with
Air Suspension, turn OFF
the Air Suspension switch prior to
jacking, hoisting or towing your
vehicle.
Normal vehicle operation does not
require any action by the driver.
TRANSMISSION OPERATION
Brake-shift interlock
This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift from being moved from P (Park) unless the brake pedal is
depressed.
If you cannot move the gearshift out of P (Park) with the brake pedal
depressed:
1.
Apply the parking brake, turn ignition key to LOCK, then remove the key.
2. Insert the key and turn it to OFF. Apply the brake pedal and shift to N
(Neutral).
3. Start the vehicle.
If it is necessary to use the above procedure to move the gearshift, it is
possible that a fuse has blown or the vehicle's brakelamps are not
operating properly. Refer toFuses and relaysin theRoadside
emergencieschapter.
Do not drive your vehicle until you verify that the brakelamps
are working.
If your vehicle gets stuck in mud or snow it may be rocked out by
shifting from forward and reverse gears, stopping between shifts, in a
steady pattern. Press lightly on the accelerator in each gear.

OFF
Driving
114

Do not rock the vehicle for more than a few minutes. The
transmission and tires may be damaged or the engine may
overheat.
Always set the parking brake fully and make sure the gearshift is
latched in P (Park). Turn off the ignition whenever you leave
your vehicle.
If the parking brake is fully released, but the brake warning lamp
remains illuminated, the brakes may not be working properly.
See your dealer or a qualified service technician.
Driving with a 4±speed automatic transmission
Understanding gearshift positions
Pull the gearshift lever towards you and downward to move the
automatic gearshift.
Hold the brake pedal down while you move the gearshift lever
from P (Park) to another position. If you do not hold the brake
pedal down, your vehicle may move unexpectedly and injure someone.
P (Park)
Always come to a complete stop
before shifting into P (Park). Make
sure the gearshift is securely latched
in P (Park). This position locks the
transmission and prevents the rear
wheels from turning.
Always set the parking brake fully and make sure the gearshift is
securely latched in P (Park).
Never leave your vehicle unattended while it is running.

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.
Roadside emergencies
123

Use the following procedure to reset the fuel pump shut-off switch.
1. Turn the ignition to the OFF position.
2. Check the fuel system for leaks.
3. If no fuel leak is apparent, reset the fuel pump shut-off switch by
pushing in on the reset button.
4. Turn the ignition to the ON position. Pause for a few seconds and
return the key to the OFF position.
5. Make a further check for leaks in the fuel system.
FUSES AND RELAYS
Fuses
If electrical components in the
vehicle are not working, a fuse may
have blown. Blown fuses are
identified by a broken wire within
the fuse. Check the appropriate
fuses before replacing any electrical
components.
Always replace a fuse with one that has the specified amperage
rating. Using a fuse with a higher amperage rating can cause
severe wire damage and could start a fire.

EMISSION CONTROL SYSTEM
Your vehicle is equipped with various emission control components and a
catalytic converter which will enable your vehicle to comply with
applicable exhaust emission standards. To make sure that the catalytic
converter and other emission control components continue to work
properly:
²Use only unleaded fuel.
²Avoid running out of fuel.
²Do not turn off the ignition while your vehicle is moving, especially at
high speeds.
²Have the items listed in your Scheduled Maintenance Guide performed
according to the specified schedule.
The scheduled maintenance items listed in the Scheduled Maintenance
Guide are essential to the life and performance of your vehicle and to its
emissions system.
If other than Ford, Motorcraft or Ford-authorized parts are used for
maintenance replacements or for service of components affecting
emission control, such non-Ford parts should be equivalent to genuine
Ford Motor Company parts in performance and durability.
Do not park, idle, or drive your vehicle in dry grass or other dry
ground cover. The emission system heats up the engine
compartment and exhaust system, which can start a fire.
Illumination of the charging system warning light, ªService Engine Soonº
light or the temperature warning light, fluid leaks, strange odors, smoke
or loss of oil pressure, could indicate that the emission control system is
not working properly.
Exhaust leaks may result in entry of harmful and potentially
lethal fumes into the passenger compartment.
Do not make any unauthorized changes to your vehicle or engine. By
law, vehicle owners and anyone who manufactures, repairs, services,
sells, leases, trades vehicles, or supervises a fleet of vehicles are not
permitted to intentionally remove an emission control device or prevent
it from working. Information about your vehicle's emission system is on
the Vehicle Emission Control Information Decal located on or near the
