The steering wheel and column components include the following components:

    • The steering wheel
    • The supplemental inflatable restraint (SIR) system inflator module, which also functions as a horn pad
    • The steering column
    • The mounting brackets

The steering column includes three important features in addition to the steering function.

    • The steering column is energy-absorbing. The column is designed to compress in a front-end collision in order to minimize the possibility of injury to the driver of the vehicle.
    • The ignition switch and the lock are mounted conveniently on the column.
    • With the column-mounted lock, the ignition, steering, and gearshifting operation can be locked in order to inhibit a theft of the vehicle.

The steering column may be disassembled and reassembled. In order to ensure the energy-absorbing action, use only the specified screws, bolts, and nuts as the fasteners are designated. Tighten the fasteners to the specified torque. Apply a thin coat of lithium grease to all friction points during assembly of the steering column components.

When the steering column is removed from the vehicle, the following types of actions may shear or loosen the plastic fasteners that maintain the steering column's rigidity:

    • Applying a sharp blow on the end of the steering shaft
    • Leaning on the column assembly
    • Dropping the assembly
