Oil Pressure Indicator (3.1L V6 Engine)
H
/
Your vehicle is equipped with an oil pressure indicator
rather than an oil pressure gage. Your oil pressure
indicator lets you know when you may have a problem
with your engine oil pressure.
When the engine is running, readings within the white
area indicate the normal operating range. Readings in or
below the red area indicate that the engine's oil level
may be dangerously low, or there may be another
problem causing low oil pressure.
Driving your vehicle with low oil pressure can cause
extensive engine damage. Have your vehicle serviced
immediately.

NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by your
warranty.
