Driving assist systems
To help enhance driving safety and performance, the following systems oper-
ate automatically in response to various driving situations. Be aware, however,
that these systems are supplementary and should not be relied upon too
heavily when operating the vehicle.
■ ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the br akes are applied suddenly, or if the
brakes are applied while driving on a slippery road surface.
■ Brake assist
Generates an increased level of braking force after the brake pedal is
depressed when the system de tects a panic stop situation.
■VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning on
slippery road surfaces.
■ TRAC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from spinning
when starting the vehicle or accelerating on slippery roads.
■Hill-start assist control
Helps to reduce the vehicle’s rolling backward distance when starting on an
incline or slippery slope.
■EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn the
steering wheel.
■VDIM (Vehicle Dynamics Integrated Management)
Provides integrated control of the ABS, brake assist, VSC, TRAC, and hill-
start assist control systems.
Helps to maintain vehicle stability when swerving on slippery road surfaces
by controlling the brakes and engine output.
When switched to SPORT driving mode, the control characteristics of the
VDIM system are altered.

When driving
Active rear wing
The LFA is equipped with an active rear wing that operates automatically
while the vehicle is being driven. This active rear wing enhances aerodynamic
performance especially at high speeds, contributing to a more stable ride.
The active rear wing can be controlled using a switch while the vehicle is
stopped.
■ Manual operation
Up
Down
■Automatic operation
The active rear wing will activate automatically as follows according to the selected
driving mode (P. 1 0 4 ) :
mph (km/h)
Always observe the legal speed limit when driving on public roads.
■Manual operating conditions
The active rear wing can be operated manu ally when the vehicle is stopped and the
ignition switch is in the “ON” position.

Launch control
When set, launch control enables the vehicle to accelerate from a standing
start at 4000 rpm. Launch control uses overall optimized control that consid-
ers vehicle acceleration performance, st ability and clutch durability. (Do not
use launch control on public roads.)
■ Setting the system
Ensure that you are seated well ba ck in the driver’s seat with the
seat belt fastened.
Make sure that the passenger is al so seated well back with their seat
belt fastened.
Start the engine. Firmly depress the brake pedal with your left
foot and release the parking brake.
Continue to depress the brake pedal.
Select SPORT driving mode.
Select shift speed level 7.
Pull the “+” paddle shift switch to select 1st gear.
Pull the “-” paddle shift swit ch and hold it for 5 seconds.
“LAUNCH” will be displayed on the meter.
Release the “-” paddle shift switch.
Depress the accelerator pedal firmly.
Continue to depress the accelerato r pedal. The engine speed will be
automatically maintained at 4000 rpm. The vehicle is then ready for
launch.
Release the brake pedal.
The vehicle will launch forward.
Once the accelerator pedal is released completely, launch control will be
canceled and SPORT driving mode will be engaged.
