- With Standard Column
Remove column as outlined under REMOVAL/INSTALLATION. The steering wheel must be straight and the column in the Lock position. Care must be taken when handling column with a live inflator module. Never point bag deploy surface toward you, and never stand column on steering wheel. Accidental deployment in these positions may cause injury. Always face bag deploy surface toward open space to allow for unrestricted expansion.
