Warning and Indicator Lights (cont'd)
Oil Pressure Warning Light
A severe fluctuation in engine oil pressure will cause this light to
flash on and off. You should stop as soon as possible, check the oil
level, and add oil if necessary.
The oil pressure warning light will come on, and remain on, if there is
insufficient oil pressure or when the ignition switch is turned on
with the engine not running. If the light should come on while driving,
get the car off the road as soon as you can, turn the engine off and
check the engine oil level (see page
Even if the oil level is correct, the engine should be checked by a
Honda dealer before the car is driven again.
NOTE:
The oil pressure warning light will only light as a result of low oil
pressure. It is not directly an oil level indicator.
CAUTION:
Running the engine while the oil pressure warning light is on
constantly may cause immediate and severe engine damage.
