The hazard

When turning the key to the ON position, the two gauges on the instrument cluster may not display the correct air pressure for the primary and secondary air tanks. When this occurs, the air gauges would remain zeroed and would not display the actual system air pressure correctly, contrary to the requirements of the standard. Correction: Dealers will perform a software update to rectify the issue.
