Basic operations
■
■Starting off

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.

■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.

covers have been designed to direct
cool air directly at the brake discs.

Refer to the following points in order to preserve the performance and appearance
of the LFA during long-term storage. These points are only guidelines. To ensure that
appropriate steps are taken in consideration of the storage duration and environment,
consult your Lexus dealer in advance.
■
■Storage environment
A dry, covered, flat location away from natural elements such as wind, rain and direct
sunlight is ideal.
Exposure to the elements can cause corrosion and scratches, while long-term
exposure to direct sunlight can cause the interior and exterior finish to fade or become
discolored. Additionally, as moisture from the ground may cause corrosion even if the
vehicle is stored in a covered location, a dry place is ideal.
■
■Cleaning
As dirt becomes harder to remove with time, both the vehicle’s interior and exterior
should be cleaned before the vehicle is put into long-term storage.
■
■Tires
Inflate the tires to approximately 44 psi (300 kPa, 3.0 kgf/cm2 or,bar,) and use wheel
chocks to prevent the vehicle from moving.
In order to help reduce flat spots from occurring during storage, regularly rotate the
tires so that the same point is n’ot always resting on the ground. Additionally, if the
tires develop flat spots during the storage interval, drive the vehicle slowly until any flat
spot-induced vibrations are no longer felt before resuming normal use.
■
■Parking brake
Use wheel chocks to prevent the vehicle from moving as it should be stored with the
parking brake disengaged.
Advice for long-term storage

If the battery is fully discharged or has insufficient charge, perform the following
procedures to gain vehicle access, release the parking brake and use another live
battery to start the engine:
■
■Unlocking the doors
The doors can be unlocked using the
master or valet keys.
If the vehicle battery is discharged

■
■Manually releasing the parking brake
Apply wheel chocks before manually releasing the parking brake.
1 Open the rear hatch and remove the
cover.

7 Select Neutral, engage the parking
brake, and turn the ignition switch to
the “LOCK” position.
8 When the LFA is completely loaded
onto the transport vehicle, secure it
with tire belts and chocks.
Be careful not to damage the tires with the
edge of the chocks.

Disabling the tilt sensor
If the tilt sensor is left on when loading the LFA onto a transport vehicle, the auto
alarm may activate.
1 Stop the engine and remove the
key.
2 Press the tilt sensor cancel switch
located inside the glove box.
