Tachometer:
Indicates the engine
speed in revolutions per minute.
Driving with your tachometer
pointer continuously at the top of
the scale may damage the engine.
Battery voltage gauge:
Indicates
the battery voltage when the
ignition is in the ON position. If the
pointer moves and stays outside the
normal operating range (as
indicated by arrows), have the
vehicle’s electrical system checked
as soon as possible.
Engine oil pressure gauge:
Indicates engine oil pressure. The
needle should stay in the normal
operating range (as indicated by the
arrows). If the needle falls below
the normal range, stop the vehicle,
turn off the engine and check the
engine oil level. Add oil if needed. If
the oil level is correct, have your
vehicle checked at your dealership
or by a qualified technician.
Air filter restriction gauge:
Measures the vacuum inside the air
cleaner. The more the air cleaner is
restricted (dirty, clogged), the
higher the vacuum reading. Change
the air filter when the gauge reads
25 inches. After installation of the
new filter element, reset the gauge
to 0.
