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.

Accelerating
■
■Driving mode-linked variable throttle response
The ratio between how far the accelerator pedal is depressed and the amount that the
throttle valves open is varied to suit the individual driving modes chosen by the driver
using the driving mode selector switch.
In AUTO mode, the maximum throttle valve angle is lowered in order to better
facilitate conservative engine speeds. This control logic was designed to promote
more efficient driving in urban situations and on long distance trips. In SPORT,
NORMAL or WET mode, the maximum throttle valve angle is unrestricted.

Regarding launch control:
Designed to make the most of the LFA’s abilities, launch control has been
adopted to automatically hold the engine speed at 4,000 rpm when starting off.
Prior to enjoying launch control,
make absolutely certain to read the appropriate
section in the Owner’s Manual.

Advice for long-term storage
■
■Battery
Removing the specified fuse helps to suppress parasitic current.
However, as the battery naturally loses its charge over time, it may become discharged
if the vehicle is stored for more than several months.
If the vehicle battery is discharged ( "

■Remove the fuse
1 Turn the ignition switch to the “LOCK” position.
2 Open the hood.

3 Open the fuse box lid in the engine
compartment.
Push the tabs in and lift the lid off.
4 While referring to the back of the fuse
box lid for the location, use the pull-
out tool A to remove the “D/C CUT”
fuse B and put it into C.
Make sure that the fuse is firmly inserted.
