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 + A
 Lexus Safety System + 2.0
 Anti-lock brake system
 Vehicle dynamics integrated man-
agement
 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.

pose of an EDR is to record, in certain
crash or near crash-like situations, such
as an air bag deployment or hitting a
road obstacle, data that will assist in
understanding how a vehicle’s systems
performed. The EDR is designed to
record data related to vehicle dynam-
ics and safety systems for a short
period of time, typically 30 seconds or
less.

Installing floor mats
A
WARNING
Observe the following precautions.
Failure to do so may cause the driver’s
floor mat to slip, poss ibly interfering with
the pedals while driving. An unexpect-
edly high speed may result or it may
become difficult to stop the vehicle. This
could lead to an accident, resulting in
death or serious injury.
■When installing the driver’s floor mat
●Do not use floor mats designed for
other models or different model year
vehicles, even if they are Lexus Genu-
ine floor mats.
●Only use floor mats designed for the
driver’s seat.
●Always install the floor mat securely
using the retaining hooks (clips) pro-
vided.
●Do not use two or more floor mats on
top of each other.
●Do not place the floor mat bot-
tom-side up or upside-down.
■Before driving
●Check that the floor mat is securely
fixed in the correct place with all the
provided retaining hooks (clips). Be
especially careful to perform this
check after cleaning the floor.
●With the engine stopped and the shift
position in P, fully depress each pedal
to the floor to make sure it does not
interfere with the floor mat.
