For your information
Main Owner’s Manual
Please note that this manual applies to all models and explains all equipment, includ-
ing options. Therefore, you may find some explanations for equipment not installed
on your vehicle.
All specifications provided in this manual are current at the time of printing. How-
ever, because of the Lexus policy of continual product improvement, we reserve the
right to make changes at any time without notice.
Depending on specifications, the vehicle sh own in the illustration may differ from
your vehicle in terms of color and equipment.
Noise from under vehicle after turning off the engine
Approximately five hours after the engine is turned off, you may hear sound coming
from under the vehicle for several minutes. This is the sound of a fuel evaporation
leakage check and, it does not indicate a malfunction.
Installation of a mobile two-way radio system
As the installation of a mobile two-way radio system in your vehicle could affect
electronic systems such as the multiport fuel injection system/sequential multiport
fuel injection system, anti-lock brake syst em, SRS airbag system and seat belt pre-
tensioner system, be sure to check with your Lexus dealer for precautionary mea-
sures or special instructions regarding installation.
Grounding of the LFA
Since the LFA is composed of CFRP (Carbo n Fiber Reinforced Plastics) body parts,
the body cannot be used as a ground terminal. As such, this vehicle has specialized
ground terminals. Consult with your Lexus dealer for the locations of the special-
ized ground terminals available for this vehicle. Do not use any portion other than
the specialized ground terminals for grounding, as doing so may cause a fire hazard.

1-6. Theft deterrent system
Tilt sensorThe tilt sensor detects changes in vehicle inclination, such as when the
vehicle is towed away.
This system is designed to deter and p revent vehicle theft but does not
guarantee absolute security against all tilts.
The tilt sensor can be canceled using the cancel switch.
Canceling the tilt sensor
Remove the key from the ignition
switch and press the tilt sensor
cancel switch in the glove box.
To set the alarm with the tilt sensor
disabled, the alarm must be set
within 5 minutes after canceling
the sensor.
The tilt sensor will revert to on each
time the ignition switch is turned to
the “ON” position.
To cancel the tilt sensor, perform the necessary procedure each time
canceling the sensors is desired.

2-1. Driving procedures
■Engine speed restrictions
The following restrictions exist for engine protection:
●The engine speed is limited to 7400 rpm if the total mileage shown on the
odometer is less than 310 miles (500 km).
●The engine speed is limited when the engine is not sufficiently warmed-up, such
as immediately after the engine is started or during the engine warm-up period.
The variable red zone shows the maximum engine speed currently available.
(  P. 1 1 9 )
●The engine speed is limited to 4400 rpm for approximately 8 minutes when the
engine is started with the coolant temperature at 5 F (-15 C) or lower.
●The engine speed may be limited when either the coolant temperature gauge
or oil temperature gauge is flashing.
■Idling with five cylinders
To improve fuel consumption, the engine may idle at a reduced speed using five cyl-
inders on one side of the engine whil e stopped or immediately before stopping
when 1st gear is selected in AUTO driving mode. During this time, “5 cylinders
idling” will be displayed on the meter an d vibration or a change in engine sound
may occur. This is normal and does not indicate a malfunction.
■ASG (Automated Sequential Gearbox) operating sounds
 P. 1 1 0
■Braking sound
●As the LFA uses CCM (Carbon Ceramic Material) brake discs with high-fric-
tion pads, it may be possible to hear the sound of the brakes operating (such as
a rubbing or squealing sound). This is normal and does not indicate a malfunc-
tion.
●The sound of a motor operating may be heard after the engine is stopped. This
does not indicate a malfunction.
■Driving in the rain
●Drive carefully when it is raining, because visibility will be reduced, the windows
may become fogged-up, and the road will be slippery.
●Drive carefully when it starts to rain, because the road surface will be especially
slippery.
●Refrain from driving at high speeds on wet surfaces such as on an expressway in
the rain, as the LFA is fitted with wide-t read tires that may increase the risk of
hydroplaning.

When driving
Shift speed selectionOne of seven different shift speeds can be selected for SPORT, NOR-
MAL, and WET driving modes using the shift speed selector. The
selected shift speed level is indicated on the meter.
Fast (shorter shifting time)
Slow (longer shifting time)
The shift speed is shown below the
speedometer. The more indicator
lights that are illuminated, the
faster the shift speed (less time
required for gear changes).

■Starting off control
The ASG does not have the creep function of a conventional automatic transmis-
sion. The vehicle can be driven by selecting 1st gear or Reverse and depressing the
accelerator pedal.
■Maximum speed for each gear
To avoid over-revving the engine, do not exceed the maximum speed for each gear
as shown below.
mph (km/h)
*: Always observe the legal speed limit when driving on public roads.
■Gear shift control
To ensure safety and driving performance, the following restrictions exist:
●Gear shifting with the paddle shift swit ches may not be possible under certain
driving conditions.
●Even while driving with a gear manually selected in SPORT, NORMAL, or
WET driving mode, the gears may change automatically under certain driving
conditions.
●If the paddle shift switches are operated repeatedly in a short space of time, a
temporary restriction of gear shifting may be activated. In this case, “Transmis-
sion pump overheat Shift rejected” will be displayed on the meter. ( P. 3 2 7 )
●Gear shifting with the paddle shift swit ches may not be possible when the trans-
mission fluid temperature is low. In this case, “Transmission temp low Shift
restricted” will be disp layed on the meter. (P. 3 2 7 )
