## Feature

This intelligent feature dynamically adjusts the side bolsters of the seat to provide optimal support and comfort, particularly during cornering.

## How it Works

### Normal Driving (Steering Wheel at Rest)

When the steering wheel is in its original, straight-ahead position (no significant turning angle), the inner airbags/chambers of the main seatback side bolsters remain deflated and inactive. The seat provides its standard level of lateral support.

### Turning

As the driver turns the steering wheel to the left by 50° or more, the inner chamber on the right side of the main seatback immediately begins to inflate. This creates an opposing lateral support against the driver's body, helping to brace them firmly against the centrifugal force of the turn. The faster the turning speed, the quicker the inflation rate, ensuring quick and effective support until the airbag is fully inflated.

Similarly, when the driver turns the steering wheel to the right by 50° or more, the inner chamber on the left side of the main seat back starts to inflate, providing support against the forces of the right turn. Again, inflation speed is proportional to turning speed.

### Returning to Straight

Once the steering wheel returns to the center or a less extreme angle, the inflated airbags automatically deflate, allowing the side bolsters to return to their normal, relaxed state.

## Benefits

### Enhanced Lateral Support

Keeps the driver and front passenger securely in place during spirited driving or sharp turns, reducing body sway.

### Improved Comfort

Minimizes fatigue on long journeys by providing dynamic support that adapts to driving conditions.

### Greater Control

By stabilizing the occupant, it allows the driver to maintain better control of the vehicle.

This feature ensures that you remain comfortably and securely cradled in your seat, adapting proactively to your driving maneuvers.
