Time LINCOLN MARK VIII 1997 Service Manual

170Have the exhaust and body ventilation systems
checked whenever:q
your vehicle is raised for service
q
the sound of the exhaust system changes
q
your vehicle has been damaged in a collision
Improve your ventilation by keeping all air inlet
vents clear of snow, leaves, and other debris.If the engine is idling while you are stopped in an
open area for long periods of time, open the
windows at least one inch (2.5 cm). Also, adjust
the heating or air conditioning system to bring in
outside air.
If you use the Electronic Automatic Climate
Control, set the fan speed selector dial to a medium
or high blower speed with the VENT or PNL-FLR
function buttons pressed.

174Manual parking brake release leverThe parking brake is not designed to stop a moving
vehicle, but you can use the parking brake to stop
your vehicle in an emergency if the normal brakes
fail. However, since the parking brake applies only
the rear brakes, the stopping distance will increase
greatly and the handling of your vehicle will be
adversely affected.Always check the Brake Warning Light each time
you start your engine. Driving with the parking
brake on will cause the brakes to wear out quickly
and will reduce the fuel economy.
Traction Control
TM
(If equipped)
Your vehicle may be equipped with the optional
Traction Control
TM
system. This system helps
prevent wheel spin in order to improve tire traction
and is an especially useful feature when you drive
in hilly areas or on slippery, icy or snowy roads.
When the Traction Control system is controlling
wheelspin, an electric motor sound may be heard
from the engine compartment and engine
acceleration may seem slower. This is normal.
Traction Control
TM
works automatically by rapidly
applying and releasing the brakes and reducing
engine torque to prevent one or both of the rear
drive wheels from spinning during acceleration.

175
NOTE:Engine torque reduction isNOTactive
when engine coolant temperature is below-10ÊF
(-23ÊC).
During the Traction Control
TM
function, which most
often occurs during low speed acceleration on
slippery surfaces, a noise may be heard coming from
the engine compartment. This is normal and may
last for a few seconds during the acceleration of the
vehicle.
In general, this system improves your vehicle's
stability and acceleration performance when road
conditions warrant. Traction Control
TM
is fully
effective at all vehicle speeds.
If the Traction Control
TM
system is cycled
excessively, the brake portion of the system will
shut down to prevent the rear brakes from
overheating. A limited Traction Control
TM
function
using engine torque will still control wheels from
spinning. A cooling down period is required to
prevent damage to the brakes. This time periodvaries and depends on brake usage during the
cooling down period. Anti-Lock braking is not
affected and will function normally during the cool
down period.
After the cool down period, the full Traction
Control
TM
function is restored.
Air Suspension SystemYour vehicle is equipped with an automatic load
leveling air suspension system. This system
maintains the vehicle height at a constant level by
automatically adding air or releasing air from the air
springs to offset changes in vehicle loads.
A shutoff switch is located in the trunk behind the
left hand vertical trim panel. If this switch is in the
OFF position, the automatic leveling system will not
operate. The switch should be OFF whenever
jacking up the vehicle. ªAIR RIDE SWITCH OFFº
will appear in the Message Center when the

180R (Reverse)With the gearshift in the R (Reverse) position, the
vehicle will move backward. You should always
come to a complete stop before shifting into or out
of R (Reverse).N (Neutral)With the gearshift in the N (Neutral) position, the
vehicle can be started and is free to roll. Hold the
brake pedal down while in this position.DrivingYour vehicle's gearshift is console-mounted on the
floor. The Transmission Control Switch (TCS) is
located on the gearshift handle. The Transmission
Control Indicator Light is located on the instrument
panel. You can put the gearshift lever in any of the
several positions.The O/D OFF light is off (not illuminated) during
normal vehicle operation. This allows the
transmission to upshift and downshift from 1st
through 4th gears. When the TCS is pressed, the
Transmission Control Indicator Light will illuminate
(O/D OFF) on the instrument panel. When this
O/D OFF is illuminated, the transmission will
upshift and downshift from 1st through 3rd gears.
If O/D OFF light does not come ªONº when TCS
is depressed or if the light flashes when you are
driving, have your vehicle serviced at the first
opportunity. If this condition persists, damage could
occur to the transmission.
To return the transmission to normal operation (1st
through 4th gear) depress the TCS again. This
switch may be used to cancel overdrive any time
the vehicle is being driven. Each time your vehicle
is started, the overdrive system will automatically be
in the normal overdrive mode and the light will not
be illuminated.

When to use D (Overdrive)Overdrive is the usual driving position for an
automatic overdrive transmission. It works the same
way Drive works, automatically upshifting or
downshifting as the vehicle speeds or slows.
However, Overdrive also shifts into a fourth gear Ð
an overdrive gear Ð when your vehicle cruises at
an appropriate consistent speed for any length of
time. This fourth gear will increase your fuel
economy when you travel at cruising speeds.When to use Drive (D Ð with
Transmission Control Switch activated)Overdrive may not be appropriate for certain
terrain. If the transmission shifts back and forth
between Third and Fourth gears while you are
driving on hilly roads or if your vehicle does not
have adequate power for climbing hills, depress the
TCS.
You can depress the TCS at any speed.
When to use 2 (Second)Use 2 (Second) for start-up on slippery roads or to
give you more engine braking to slow your vehicle
on downgrades.When to use 1 (Low)Use 1 (Low) when driving down steep grades. It
gives more engine braking to slow your vehicle than
2 (Second) on the downgrades. You can upshift
from 1 (Low) to 2 (Second) or from 1 (Low) to
Overdrive at any speed.P (Park)Always come to a complete stop before you shift
into P (Park). Make sure that the gearshift is
securely latched in P (Park). This locks the
transmission and prevents the rear wheels from
rotating.
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.

Checking and Adding Engine OilSince the proper amount of engine oil is important
for safe engine operation, check the oil using the
dipstick each time you put fuel in your vehicle.
Remember the engine must be off, the oil must be
warm and the vehicle must be parked on level
ground.
Checking the engine oil level:
1. Turn the engine off after it has warmed up and
allow a few minutes for the engine oil to drain
back into the oil pan.
2. Set the parking brake, making sure the gearshift
is securely latched in P (Park).
3. Open the hood. Protect yourself from engine
heat.
4. Locate the engine oil dipstick (highlighted in
yellow) and carefully pull it out of the engine.5. Wipe the dipstick clean and put it back into
position, making sure it is fully seated.
Engine oil dipstick
6. Carefully, pull the dipstick out again and read
it. If the oil level is below the MIN line, add a
half quart of engine oil as necessary. If the oil
level is above the MAX line, engine damage or
high oil consumption may occur and some oil
must be removed from the engine.
7. Put the dipstick back in and make sure it is
fully seated.

224It may be necessary to add some oil between oil
changes. Make sure you use a CERTIFIED engine
oil of the preferred viscosity. Your vehicle's
warranty coverage may not apply if engine damage
is caused by the use of improper engine oil.
Add engine oil through the oil filler cap highlighted
in yellow. To add oil, remove the filler cap and use
a funnel to pour oil into the opening. Be careful not
to overfill the engine. Recheck the oil level after
you finish adding oil.Changing the Engine Oil and the Oil
FilterYour vehicle has an OIL LIFE LEFT function as part
of the Vehicle Message Center (M/C). This device
displays the percent of useful engine oil life left and
when an oil change is required. Use of a
CERTIFIED oil of the preferred viscosity is required
for this device to work properly. Change your
engine oil and oil filter when the message centerdisplaysCHANGE OIL SOON or OIL CHANGE
REQUIRED. If the Message Center malfunctions,
you may determine your oil change interval based
on the following guidelines.
Change your engine oil and oil filter according to
these mileage and time requirements, whichever
occurs first.

Power Steering FluidCheck the level of the power steering fluid at least
twice a year (i.e., every Spring and Fall).Checking and Adding Power Steering
Fluid1. Start the engine and let it run until the power
steering fluid reaches normal operating
temperature. The power steering fluid will be at
the right temperature when the engine coolant
temperature gauge in the instrument cluster is
near the center of the NORMAL operating
temperature range.
2. While the engine idles, turn the steering wheel
back and forth several times. Make sure that
the cap assembly is installed at this time.3. Turn the engine off and check the level on the
power steering reservoir.
4. The fluid level is viewed through the sight
window on the power steering reservoir. If the
power steering fluid is below the middle line,
add fluid in small amounts, continuously
checking the level. Do not overfill.

234Fluid level for power steeringUse only MERCONHATF power steering fluid.If the power steering fluid is low, do not drive your
vehicle for a long period of time before adding fluid.
This can damage the power steering pump.
Automatic Transmission FluidUnder normal circumstances, you do not need to
check the fluid level of the transmission, since your
vehicle does not use up transmission fluid. Refer to
theMaintenance Schedulebooklet for replacement
intervals. However, if the transmission is not
working properly Ð for instance, the transmission
may slip or shift slowly, or you may notice some
sign of fluid leakage Ð the fluid level should be
checked.
It is preferable to check the transmission fluid level
at normal operating temperature150ÊF-170ÊF
(66ÊC-77ÊC),after approximately 20 miles (30 km)
of driving. However, if necessary, you can check
the fluid level without having to drive 20 miles
(30 km) to obtain a normal operating temperature if
outside temperatures are above50ÊF(10ÊC).

NOTE:If the vehicle has been operated for an
extended period at high speeds or in city traffic
during hot weather, or pulling a trailer, the vehicle
should be turned off for about 30 minutes to allow
the fluid to cool before checking.Checking the Automatic Transmission
FluidWith the vehicle on a level surface and the brake
fully applied, start the engine and move the gear
shift selector through all of the gears allowing
sufficient time for each position to engage. Securely
latch the gear shift selector in the P (Park) position.
Fully set the parking brake and leave the engine
running.
NOTE:Your vehicle should not be driven if the
fluid level does not appear on the dipstick tip and
outside temperatures are above50ÊF(10ÊC).
Wipe off the dipstick cap and pull the dipstick out.
Wipe the indicator end clean. Put the dipstick back
into the filler tube and make sure it is fully seated.Pull the dipstick out and read the fluid level.
When checking fluid at normal operating
temperatures150ÊF-170ÊF (66ÊC-77ÊC), thefluid
level should be within the ªHOTº notched area on
the dipstick. When the vehicle has not been driven,
and outside temperatures are above68ÊF(20ÊC),
the fluid levels should be between the ªHOTº
notch and the tip end of the dipstick.
Adding Automatic Transmission FluidBefore adding any fluid, be sure that the correct
type will be used. Use only MerconHFluid, as
shown on handle.
Add fluid in 1/2 pint (250ML) increments through
the filler tube to bring the level to the correct area
on the dipstick. DO NOT OVERFILL. If the level is
above the top hole on the dipstick, excess fluid
should be removed by a qualified technician.
