Mercury 2000 Grand Marquis - Manual (Page 19)

• Optional instrument cluster
This gauge indicates the temperature of the engine coolant, not the
coolant level. If the coolant is not at its proper level the gauge indication
will not be accurate. If the gauge enters the red section, the engine
coolant and Check Engine/Service Engine Soon indicators illuminate,
refer to What you should know about fail-safe cooling in the
Maintenance and care chapter.
Battery voltage gauge (if equipped)
This shows the battery voltage when
the ignition is in the ON position. If
the pointer moves and stays outside
the normal operating range (as
indicated), have the vehicle’s
electrical system checked as soon as
possible.
Engine oil pressure gauge (if equipped)
This shows the engine oil pressure
in the system. Sufficient pressure
exists as long as the needle remains
in the normal range (the area
between the “H” and “L”).
If the gauge indicates low pressure,
stop the vehicle as soon as safely
possible and switch off the engine
immediately. Check the oil level.
