Oil Pressure Gage Digital Cluster Standard a I I Cluster I The oil pressure gage shows the engine oil pressure in psi (pounds per square inch) when theengine is running. Canadian vehiclesindicate pressure in kPa (kilopascals). Oil pressure may vary with engine speed, outside temperature and oil viscosity, but readings above the low pressure zone indicate the normal operating range. A reading in the low pressure zone may be causedby a dangerously lowoil level or other problems causing low oil pressure. On the digital cluster, a box around oil pressure symbol will beginto the flash when the oil pressure is low. 2-62
