What is a feature that provides adjustability in the QX55?

The feature that provides adjustability in the QX55 is the power-adjustable steering column. This feature allows drivers to easily modify the position of the steering wheel to suit their comfort and driving preferences, enhancing overall driving experience and ergonomics.

In contrast, a manual steering column does not offer the same convenience and flexibility as the power-adjustable option since it requires physical effort to adjust and lacks the precision of electric controls. A fixed steering column provides no adjustability at all, limiting drivers to a single position that may not be ideal for everyone. Adjustable seat height could contribute to comfort as well, but it specifically pertains to the driver's seating position rather than the steering column, which is a distinct part of vehicle control and driving comfort. Therefore, the power-adjustable steering column stands out as the primary feature that provides adjustability.
