■Driving position adjustment
1 Insert the key into the ignition switch
and then turn the key to the “ACC”
position.
2 Use the seat adjustment switches (A)
to move the driver seat. You should
be able to fully depress the brake
pedal with your knees slightly bent.
3 Adjust the height of the seat and the
position of the steering wheel. You
should be able to grip the top of the steering wheel with your elbows slightly bent
and your back at a comfortable angle.
4 If necessary, readjust the seat position.
5 Adjust the mirrors to ensure that you have a good view of the area behind the
vehicle.
■
■Starting the engine
1 With the brake pedal depressed, turn the key to the “ON” position.
2 Pull both paddle shift switches at the same time to select Neutral.
3 Press the “ENGINE START” switch to start the engine.

Basic operations
■
■Starting off
1 With the brake pedal depressed, pull the right paddle shift switch to select 1st gear.
2 Pull the parking brake switch to release the parking brake.
3 Release the brake pedal and then slowly depress the accelerator pedal.
■
■Reversing
1 With the vehicle stationary, depress the brake pedal and check the gear indicator
in the meter to ensure that Neutral is selected.
2 Pull the reverse selector switch to select Reverse.
3 Release the brake pedal and then slowly depress the accelerator pedal.
It is not possible to change directly from Reverse to any of the forward gears. Select Neutral first
and then select a forward gear.
■
■Parking
1 Depress the brake pedal until the vehicle comes to a complete stop.
2 Press the parking brake switch to set the parking brake.
3 Ensure that “D1”, “1” or “R” is displayed on the gear indicator.
4 Push in the key and turn it to the “LOCK” position to stop the engine.
The “ENGINE START” switch is for starting the engine. It cannot be used to stop the engine.

■Brake caliper
The LFA features front 6-piston and rear
4-piston aluminum alloy monoblock
calipers with dif ferential piston bore
sizing. This design takes advantage of
what is known as the 'self-servo effect',
allowing pressure from the unequally
sized pistons to push the pad against the
rotor in a progressive pattern, with the
leading piston applying the least force
and the trailing edge applying the most.
This wedge shape uses the rotational
movement of the disc to help the brake
p a d s ' b i t e ' i n t o t h e d i s c w i t h m o r e
effective pressure distribution, optimized
pressure equalization that helps realize
a more consistent supply of stopping
power. The LFA also features track-bred brake cooling ducts in the front bumper and
aerodynamic under covers designed to channel fresh, cool air to the brake system.
Each brake caliper piston (Front: 12
Rear: 8) employs a thermally insulated
aluminum construction with cooling
holes to help prevent the brake fluid from
boiling for enhanced high-temperature
endurance.
Parking brake calipers have been adopted
in order to lower vehicle weight. A switch-
operated EPB (Electric Parking Brake)
function has been adopted.

The shape of the cooling ducts in the
front bumper and contours of the under
covers have been designed to direct
cool air directly at the brake discs.

■Brake discs
Each brake disc is made from CCM (Carbon Ceramic Material) and features a two-
piece floating construction with an aluminum center hat. With this construction, disc
deformation due to expansion at high temperatures is more effectively mitigated;
thereby enabling a more consistent application of pressure from the brake pads for
stable and confidence-inspiring brake performance under any circumstances.
CCM discs provide the high stopping

power and thermal capacity needed
to provide consistent braking at high
speeds.
The discs are impregnated with silicone
material to ensure outstanding stopping
power and endurance when they are not
yet at optimal operating temperature or
in wet conditions. However, one should
avoid spraying water directly onto a hot
brake disc. Fur thermore, CCM discs
are susceptible to microscopic cracking
and local damage resulting from a direct
impact. Care is required when installing a
tire and wheel as accidental contact may
result in damage.

Bedding-in new brake pads or rotors:
In order to ensure maximum performance from a set of replacement CCM discs
or brake pads, it is necessary to bed them in. Please consult your Lexus dealer
regarding the appropriate bedding procedure. The LFA is shipped from the factory
with pre-bedded CCM discs and brake pads.
The disc diameters are 15.35 in. (390
mm) for the front and 14.17 in. (360 mm)
for the rear. Both front and rear discs are
ventilated with 0.20 in. (5 mm) diameter
d r i l l e d c o o l i n g h o l e s . T h e a d o p t i o n o f
CCM as opposed to conventional cast-iron
results in a reduction in unsprung weight of
approximately 11.03 lb. (5 kg) per wheel.
