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.

When driving
Starting on a steep uphillThe hill-start assist control ( P. 166) operates to help reduce the dis-
tance that the vehicle rolls backward when starting on an incline. How-
ever, under certain conditions hill-start assist control may not work. In that
case, follow the procedure below.
Make sure that the parking brake is set and select 1st gear.
Gently depress the accelerator pedal.
Release the parking brake.
■Shifting gears
P. 1 0 2
■Breaking in your new LFA
To extend the life of the vehicle, observing the following precautions is recom-
mended:
●For the first 186 miles (300 km):
Avoid sudden stops.
●For the first 621 miles (1000 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in low gears.
• Do not drive at a constant speed for extended periods.

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.
