Please note that this manual applies to
all models and explains all equipment,
including options. Therefore, you may
find some explanations for equipment
not installed on your vehicle.
All specifications provided in this man-
ual are current at the time of printing.
However, 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 vehi-
cle shown in the illustrations may differ
from your vehicle in terms of color and
equipment.
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.
A wide variety of non-genuine spare
parts and accessories for Lexus vehi-
cles are currently available in the mar-
ket. You should know that Toyota does
not warrant these products and is not
responsible for their performance, repair, or replacement, or for any dam-
age they may cause to, or adverse
effect they may have on, your Lexus
vehicle.
This vehicle should not be modified
with non-genuine Lexus products.
Modification with non-genuine Lexus
products could affect its performance,
safety or durability, and may even vio-
late governmental regulations. In addi-
tion, damage or performance
problems resulting from the modifica-
tion may not be covered under war-
ranty.
The installation of a mobile two-way
radio system in your vehicle could
affect electronic systems such as:

Multiport fuel injection sys-
tem/sequential multiport fuel injec-
tion system
 Lexus Safety System+ 2.0
 Anti-lock brake system
 SRS airbag system
 Seat belt pretensioner system
Be sure to check with your Lexus
dealer for precautionary measures or
special instructions regarding installa-
tion of a mobile two-way radio system.
The vehicle is equipped with sophisti-
cated computers that will record cer-
tain data, such as:

puters do not record conversations or
sounds, and only record images out-
side of the vehicle in certain situations.
• Engine speed/Electric motor speed
(traction motor speed)
• Accelerator status
•Brake status
• Vehicle speed
• Operation status of the driving assist systems, such as the ABS and
pre-collision system

Your vehicle may transmit the data
recorded in these computers to Lexus
without notification to you.
Data usage
Lexus may use the data recorded in this
computer to diagnose malfunctions, con-
duct research and development, and
improve quality.

a third party except:
• With the consent of the vehicle owner or with the consent of the lessee if the vehi-
cle is leased
• In response to an of ficial request by the
police, a court of law or a government
agency
• For use by Lexus in a lawsuit
• For research purposes where the data is not tied to a specific vehicle or vehicle owner


data recorder (EDR). The main pur-
pose of an EDR is to record, in certain
