Low Oil Pressure Warning
Should the oil pressure drop to a dangerously low
level, the SystemCheck engine monitor will sound
the horn and turn on   the “NO OIL” light. Also,  the
EMM  will  immediately  limit  the  engine  speed  to
3000 RPM. This additional protective feature is re-
ferred to as S.L.O.W. If the engine was running fast-
er  than  3000  RPM   when  the  S.L.O.W.  system
activated, it will shake noticeable.
If  the  warning  light  stays  on  after  two  minutes,
STOP the engine and see your Dealer.
In case of low oil pressure:
IMPORTANT: You must restore cooling to the en-
gine to avoid serious engine damage.
Shut OFF engine.
If tilted, place the engine in vertical position.
After any overheat, have your Dealer:
Torque the cylinder head screws.
Inspect the water pump for excessive wear or dam-
age.
Inspect the thermostats.
Inspect the engine for leaks.
Inspect water pressure valve.
Check engine oil level.
Check the oil level on the dipstick and add oil, if
needed.  Refer  to  Crankcase  Oil  and  Filter  and
Engine Specifications.
Examine the oil fill cap, filter, and drain screw for ev-
idence of leakage. Make sure each is tight.
If dipstick shows that the oil level is okay, leave the
engine  upright  and  shut  off  for  10  minutes,  then
start it. If the engine still limits itself to about 3000
RPM, see your Dealer.
IMPORTANT: DO NOT attempt to run your engine
if it repeatedly loses oil pressure. See your Dealer.
