Please note that this manual applies to
all models and explains all equipment,
including options. Therefore, you may
find explanations for equipment not
installed on your vehicle and the illus-
trations used may differ from your vehi-
cle.
All specifications provided in this man-
ual are current at the time of printing.
Over time, your vehicle may receive
updates that modify the vehicle and
make material in this manual incom-
plete and/or inaccurate. Because of
Lexus’ interest in continual product
improvement, Lexus reserves the right
to make changes to this manual at any
time without notice.
If Lexus chooses to update the manual,
updated versions can be viewed by

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.
Also, remodeling like this will have an
effect on advanced safety equipment
such as Lexus Safety System + 2.0 and
there is a danger that it will not work
properly or the danger that it may work
in situations where it should not be
working.
The installation of a mobile two-way
radio system in your vehicle could
affect electronic systems such as:

into the floor mat eyelets.
2 Turn the upper knob of each retain-
ing hook (clip) to secure the floor

Installing floor mats
A
WARNING
Observe the following precautions.
Failure to do so may cause the driver’s
floor mat to slip, possibly 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 di fferent 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
lever in P, fully depress each pedal to
the floor to make sure it does not inter-
fere with the floor mat.
