Energy Absorbing Mechanism (Models with Manual Tilt and Manual Telescopic Steering Column)
The energy absorbing mechanism in the steering column assembly consists of a main shaft column tube and No. 2 steering intermediate shaft assembly.

The steering column assembly is mounted on the instrument panel reinforcement assembly via a breakaway bracket. The steering column assembly and the power steering link assembly are connected with a contractile No. 2 steering intermediate shaft assembly.
When the power steering link assembly moves during a collision (primary collision), the No. 2 steering intermediate shaft assembly contracts, thus helping reduce the possibility of the steering column assembly and the steering wheel assembly protruding into the cabin.
When a collision impact is transmitted to the steering wheel assembly (secondary collision), the steering wheel assembly and the driver's airbag help absorb the impact. In addition, the breakaway bracket separates, and the column tube contracts. At this time, the friction resistance of the sliding portion absorbs the energy. This sequential energy absorbing mechanism helps absorb the impact of the secondary collision.

Energy Absorbing Mechanism (Models with Power Tilt and Power Telescopic Steering Column)
The energy absorbing mechanism mainly consists of a breakaway bracket, energy absorbing plate, No. 2 steering intermediate shaft assembly and column tube. The tilt steering gear with motor assembly is mounted on the instrument panel reinforcement assembly via a breakaway bracket. The tilt steering gear with motor assembly and the power steering link assembly are connected with a contractile No. 2 steering intermediate shaft assembly.

When the power steering link assembly moves during a collision (primary collision), the No. 2 steering intermediate shaft assembly contracts, thus helping reduce the possibility of the tilt steering gear with motor assembly and the steering wheel assembly protruding into the cabin.
When a collision impact is transmitted to the steering wheel assembly (secondary collision), the steering wheel assembly and the driver's airbag help absorb the impact.
The energy absorbing plate deforms, and the column tube contracts.
