Engine Oil Pressure Gauge
[LG16500( ALL)05/94]
This gauge indicates the engine oil pressure, not
the oil level. However, if your engine's oil level
is low, it could affect the oil pressure. With the
engine running, the pointer should move into
the NORMAL band. If the pointer drops below
the NORMAL band while the engine is running,
you have lost oil pressure and continued
operation will cause severe engine damage.
*
[LG16600( ALL)03/95]
If you lose engine oil pressure:
*
[LG16700( ALL)01/95]
1. Pull off the road as soon as safely possible.
*
[LG16800( ALL)04/95]
2. Shut off the engine immediately or severe
engine damage could result.
[LG16900( ALL)05/94]
3. Check the engine's oil level, following the
instructions on checking and adding engine
oil, see theEngine Oilin the Index. If you do
not follow these instructions, you or others
could be injured. To assure an accurate
reading, your car should be on level ground.
[LG17000( ALL)05/94]
4. If the level is low, add oil as necessary
before you start the engine again. Do not
overfill. Do not operate the engine if the
pointer is below the NORMAL band,
regardless of the oil level. Contact your
nearest dealer for further service actions.

Check Engine Warning Light
*
[LG27650( GV)03/95]
The Powertrain On-Board Diagnostic II (OBD II)
system consists of the hardware and software
necessary to monitor the operation of the
powertrain. The OBD II system is designed to
check the function of the vehicle's powertrain
control system during normal operation. If an
emission problem is detected, the Check Engine
Warning Light (in the cluster) is turned on.
*
[LG27750( GV)03/95]
Modification or additions to the vehicle may
cause incorrect operation of the OBD II system.
Additions such as burglar alarms, cellular
phones, and CB radios must be carefully
installed. Do not install these devices by tapping
into or running wires close to powertrain control
system wires or components.

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

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.

is low, it could affect the oil pressure. The light
should come on every time your ignition key is
