The light comes on briefly when you turn the
ignition key toON, but it should turn off when
the engine starts. If the light does not come on
when you turn the ignition toONor if it comes
on and stays on when you are driving, have
your vehicle serviced as soon as possible. This
indicates a possible problem with one of the
vehicle's emission control systems. You do not
need to have your vehicle towed in.
*
[LG27815( GV)04/95]
If the light turns on and off at one (1) second
intervals while you are driving the vehicle, it
means that the engine is misfiring. If this
condition persists, damage could occur to the
engine or catalytic convertor. Have your vehicle
serviced at the first opportunity. You do not
need to have your vehicle towed in.
*
[LG27820( GV)03/95]
If the light turns on and off on rare occasions
while you are driving, it means that a
malfunction occurred and the condition corrected
itself.
*
[LG27825( GV)03/95]
An example of a condition which corrects itself
occurs when an engine running out of fuel
begins to misfire. In this case, the Check Engine
Warning Light may turn on and will then set a
Diagnostic Trouble Code indicating that the
engine was misfiring while the last of the fuel
was being consumed. After refueling, the Check
Engine Warning Light will turn off after the
vehicle has completed three consecutive warm
up cycles without a misfire condition occurring.
A warm up cycle consists of engine start from a
cold condition (engine at ambient temperature)
and running until the engine reaches normal
operating temperature.
*
[LG27850( GV)03/95]
On the fourth engine start up, the Check Engine
Warning Light will turn off as soon as the
engine begins to crank. It is not necessary to
have the engine serviced.

Air Bag Readiness Light
[LG28102( GV)02/93]
The Air Bag Readiness light will go on each
time you start your vehicle and will remain on
for about 6-8 seconds indicating normal air bag
operation. If this light stays on continuously or
flashes, or if the light never comes on at all,
there is something wrong with the Air Bag
Supplemental Restraint System and your vehicle
should be taken in for service to the nearest
Lincoln-Mercury dealer as soon as possible.
Unless serviced, the Air Bag Supplemental
Restraint System may not function properly in
the event of a collision.

This light indicates the engine oil pressure, not
the oil level. However, if your engine's oil level
is low, it could affect the oil pressure. The light

[LG28112( GV)03/95]
1. Pull off the road as soon as safely possible.
*
[LG28113( GV)01/95]
2. Shut off the engine immediately. If you do
not stop the engine as soon as safely
possible, severe engine damage could result.
[LG28114( GV)07/94]
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.
[LG28115( GV)06/93]
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.

(If equipped)
*
[LG54300( GV)01/95]
This warning light will go on each time you
start your vehicle. If it remains on for longer
than 5 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.
*
[LG54400( GV)01/95]
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.
