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.

facility that generates strong radio waves or electrical noise, an audio or other
radio wave emitting device or a large display
●When carrying a portable radio, cellular phone, cordless phone or other wire-
less communication device

Safety information for Safety ConnectImportant! Read this information before using Safety Connect.
■ Exposure to radio frequency signals
The Safety Connect sy stem installed in your ve hicle is a low-power
radio transmitter and receiver. It receives and also sends out radio fre-
quency (RF) signals.
In August 1996, the Federal Communications Commission (FCC)
adopted RF exposure guidelines with safety levels fo r mobile wireless
phones. Those guidelines are consistent with the safety standards pre-
viously set by the following U.S. and international standards bodies.
● ANSI (American National Standards Institute) C95.1 [1992]
● NCRP (National Council on Radi ation Protection and Measure-
ment) Report 86 [1986]
● ICNIRP (International Commission on Non-Ionizing Radiation Pro-
tection) [1996]
Those standards were based on co mprehensive and periodic evalua-
tions of the relevant scientific literature. Over 120 scientists, engineers,
and physicians from universities, an d government health agencies and
industries reviewed the available body of research to develop the
ANSI Standard (C95.1).
The design of Safety Connect co mplies with the FCC guidelines in
addition to those standards.
