[IS02000( BCGV)01/96]
The following warning lights and gauges are on
the mechanical cluster. All of the warning lights
and gauges alert you to possible problems with
your vehicle. Some of the lights listed are
optional. The following sections detail what each
of these indicators means.

[IS02600( ALL)01/96]
Brake System Warning Light
*
[IS02700( ALL)03/96]
The warning light for the brakes can show two
things Ð that the parking brake is not fully
released, or that the brake fluid level is low in
the master cylinder reservoir. If the fluid level is
low, the brake system should be checked by a
qualified service technician.
[IS02800( BC )04/96]

The brake system warning light
[IS03100( ALL)12/95]
This light comes on when the parking brake is
set, or if it is not set, it comes on briefly when
you turn the ignition key to START. It normally
goes off shortly after the engine starts and you
release the parking brake. If the light stays on
after you have fully released the parking brake,
have the hydraulic brake system serviced.
*
[IS03200( ALL)03/96]
RWARNING
The BRAKE light indicates that the brakes
may not be working properly. Have the
brakes checked immediately.

Anti-Lock Brake System Light
(If equipped)
[IS03400( ALL)12/95]
This warning light will go on each time you
start your vehicle. If it remains on for longer
than five seconds, you should shut off your
engine and restart. If the anti-lock brake light
stays on, this indicates that the anti-lock feature
is disabled and should receive immediate
attention by a qualified service technician.
Normal braking is not affected unless the brake
warning light is also lit.
*
[IS03500( ALL)03/96]
The Anti-Lock Brake System has self-check
capabilities. As previously described, the system
turns on the anti-lock light each time you start
your engine. After the engine is started and the
anti-lock light is out, the system performs
another test the first time the vehicle reaches
14 mph (22 km/h). The system turns on the
Anti-Lock Brake System (ABS) pump motor for
approximately 1/2 second. At this time a
mechanical noise may be heard. This is a normal
part of the self-check feature. If a malfunction is
found during this check the anti-lock light will
come on.

Air Bag Readiness Light
*
[IS06400( ALL)04/96]
The air bag system uses a readiness light and a
tone to indicate the condition of the system. The
readiness light is in the instrument cluster. When
you turn the ignition key to the ON position,
this light will light up for six (6) seconds and
then turn off. This indicates that the system is
operating normally. NOTE: Regularly scheduled
maintenance of the air bag system is not
required.
*
[IS06500( ALL)04/96]
If the light fails to illuminate, continues to flash,
remains on, or you hear a beeping sound, have
the system serviced at your Ford or
Lincoln-Mercury dealer immediately.

This light tells you that the coolant is low inside
the coolant recovery bottle and that you should
add more coolant.
[IS07300(MBC )04/96]
This light comes on for a few seconds when
your ignition key is turned to start, but should
turn off when the engine starts. If this light stays
on, check the level of coolant inside the recovery
bottle. SeeEngine Coolantin the Index.

3. Check the engine's oil level, following the
instructions on checking and adding engine
oil, seeEngine Oilin the Index. If you do
not follow these instructions, you or others
could be injured. To assure an accurate
reading, your vehicle should be on level
ground.
[IS13600( BC )03/96]
4. If the level is low, add only as much oil as
necessary before you start the engine again.
Do not overfill. Do not operate the engine if
the light is on, regardless of the oil level.
Contact your nearest dealer for service as
soon as possible.

[TO03600( ALL)01/96]
A computer system controls the engine's idle
speed. When you start your vehicle, the engine's
idle speed normally runs higher than when it's
warmed up. These faster engine speeds will
make your vehicle move slightly faster than its
normal idle speed. It should, however, slow
down after a short time. If it does not, have the
idle speed checked.
*
[TO03700( ALL)01/96]
If the engine idle speed does not slow down
automatically, do not allow your vehicle to idle
for more than 10 minutes. Have the vehicle
checked.
*
[TO03800( ALL)01/96]
RWARNING
Extended idling at high engine speeds can
produce very high temperatures in the
engine and exhaust system, creating the
risk of fire or other damage.
*
[TO03900( ALL)01/96]
RWARNING
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.
*
[TO04000( ALL)01/96]
If you consistently start your vehicle in subzero
temperatures, use an engine block heater (if
your vehicle has this option).
%*
[TO04100( ALL)01/96]
Engine Block Heater (If equipped)
*
[TO04200( ALL)01/96]
Engine block heaters are strongly recommended
if you live in a region where temperatures reach
-10ÊF (-23ÊC) orbelow. An engine block heater
warms the engine coolant, which improves
starting, warms up the engine faster, and allows
the heater-defrost system to respond quickly.

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.
[GF03300( BC )12/95]
To release the parking brake, press down on the
pedal until you hear a click. Lift your foot off
the pedal. The brake is now released and will
reset to lock the next time you press the pedal,
located below the lower left corner of the
instrument panel. The Brake System Warning
Light will glow if the parking brake is not fully
released when the engine is running.
*
[GF03600( ALL)01/96]
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.

RWARNING
If the parking brake is fully released, but
the Brake System light remains on, have
the brakes checked immediately. They
may not be working properly.
[GF03800( ALL)12/95]
The parking brake system is designed for static
parking only and 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.
% [GF03900( ALL)12/95]Traction-Lok Axle (If equipped)
[GF04000( ALL)12/95]
This axle provides added traction on slippery
surfaces, particularly when one wheel is on a
poor traction surface. Under normal conditions
the Traction-Lok axle functions as a standard
rear axle.
*
[GF04100( ALL)03/96]
Extended use of other than matching size tires
on a Traction-Lok rear axle could result in a
permanent reduction in effectiveness. This loss of
effectiveness does not affect normal driving and
should not be noticeable to the driver.
*
[GF04200( ALL)05/96]
RWARNING
To avoid injury, never run the engine
with one wheel off the ground, such as
when changing a tire.

Changing a Tire
*
[ER09400( ALL)02/96]
If you get a flat tire while you are driving, do
not apply the brake heavily. Instead, gradually
decrease the speed. Hold the steering wheel
firmly and slowly move to a safe place on the
side of the road. Park on a level spot, turn off
the ignition, set the parking brake, and turn on
the hazard flashers.

The Temporary Spare Tire
[ER09700(MBC )02/96]
You have a high pressure temporary spare tire.
This spare tire is smaller than a regular tire and
is designed for emergency use only. Use it only
when you get a flat tire and replace it as soon
as you can. This spare tire is marked with the
words ªTEMPORARY USE ONLYº so that you
can easily identify it.

Turning on the fan helps protect the
electrical system from voltage surges. Turn
off all other switches and lights in both

1. Connect one end of the first jumper cable to
the positive (+) terminal of the discharged
battery. (You can connect either jumper cable
to the positive (+) terminal, as long as you
use the same cable for both positive
terminals.) Most jumper cables have a red
cable and a black cable. The red cable is
generally used for the positive terminals and
the black for the negative ones.
