Ideal Driving Position; Seat Slide Adjustment; Seat Angle Adjustment - Lexus LFA Owner's Manual

Ideal driving position

An ideal driving position allows for smooth operational inputs and also helps to
reduce injuries in the event of a collision. Although the driving position employed by
racing drivers in competition offers maximum car control, it is not always practical for
use on public roads.
While the ideal driving position will vary depending on individual requirements and
driving conditions, please observe the following points in order to ensure a safe and
comfortable driving position:
■ ■

Seat slide adjustment

When sliding your seat back and forth, aim for a position that allows you to fully
depress the brake pedal with your knees slightly bent. Also, to ensure that you have
enough leverage to depress the brake pedal, make sure that your back rests firmly
against the seatback.
If your leg is fully extended to depress the brake pedal and a collision occurs, your
knee will not be able to help absorb any impact force. Instead, the full force of the
impact will be transferred to your lower back, possibly resulting in spinal injuries.
■ ■

Seat angle adjustment

When adjusting the seatback, aim for an angle that allows you to rest your back firmly
against the seatback with your hands gripping the top of the steering wheel and your
elbows slightly bent. Resting your back firmly against the seatback offers better body
support.
To maintain an adequate level of support, it is essential to make sure that your arms are
not over-reaching to touch the top of the steering wheel. Sitting too far away will force
you to lean forward when turning, compromising the support offered by the seatback.
Finally, make sure that the seatback is not reclined excessively, as this may result in
your body slipping under the seat belt in the event of a collision.
The seats in the LFA employ a racing bucket seat-inspired design and frames made
from CFRP (Carbon Fiber Reinforced Plastics) to ensure a highly rigid and supportive
construction.
To ensure that the seats are used to their maximum potential, always maintain an
appropriate driving position.
