For your information
Please note that this manual applies to all models and explains all equipment, including
options. Therefore, you may find some expl anations for equipment not installed on your
vehicle.
All specifications provided in this manual are current at the time of printing. However,
because of the Lexus policy of continual pr oduct improvement, we reserve the right to
make changes at any time without notice.
Depending on specifications, th e vehicle shown in the illustrations may differ from your
vehicle in terms of color and equipment.
Approximately five hours after the hybrid system is turned off, you may hear sound com-
ing 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 vehicles are cur-
rently available in the market. You should kn ow that Toyota does not warrant these prod-
ucts and is not responsible fo r their performance, repair, or replacement, or for any
damage 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 violate governmental regulations. In addition, damage or performance problems
resulting from the modification may not be covered under warranty.
The installation of a mobile two-way radio system in your vehicle could affect electronic
systems such as:
●Multiport fuel injection system/seque ntial multiport fuel injection system
●Lexus Safety System+
●Cruise control system
●Anti-lock brake system
●Vehicle dynamics integrated management
●SRS airbag system
●Seat belt pretensioner system
Be sure to check with your Lexus dealer for precautionary measures or special instruc-
tions regarding installation of a mobile two-way radio system.
High voltage parts and cables on the hybrid vehicles emit approximately the same
amount of electromagnetic waves as the co nventional gasoline powered vehicles or
home electronic appliances despite of their electromagnetic shielding.
Unwanted noise may occur in the rece ption of the mobile two-way radio.

For safety and security
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
●Do not adjust the position of the driver’s seat while driving.
Doing so could cause the driver to lose control of the vehicle.
●Do not place a cushion between the dr iver or passenger and the seatback.
A cushion may prevent correct posture from being achieved, and reduce the effec-
tiveness of the seat be lt and head restraint.
●Do not place anything under the front seats.
Objects placed under the fr ont seats may become jammed in the seat tracks and stop
the seat from locking in plac e. This may lead to an accident and the adjustment mech-
anism may also be damaged.
●Always observe the legal speed limi t when driving on public roads.
●When driving over long distances, take regular breaks before you start to feel tired.
Also, if you feel tired or sleepy while drivin g, do not force yourself to continue driving
and take a break immediately.

For safety and security
For children or smaller-than-average
people, slide the seat belt comfort
guide forward so that the shoulder belt
does not sit close to the person’s neck.
The pretensioner helps the seat belt to
quickly restrain the occupant by
retracting the seat belt when the vehi-
cle is subjected to certain types of
severe frontal collision.
The front seat pretensioners also acti-
vate when the vehicle is subjected to
certain types of severe side collision.
The pretensioner does not activate in the event of a minor frontal impact, a minor side
impact, a rear impact or a vehicle rollover.
■Emergency locking retractor (ELR)
The retractor will lock the belt during a sudden stop or on impact. It may also lock if you
lean forward too quickly. A slow, easy motion w ill allow the belt to extend so that you can
move around fully.
■Automatic locking retractor (ALR)
When a passenger’s shoulder belt is completely extended and then retracted even
slightly, the belt is locked in that position and cannot be extended. This feature is used to
hold the child restraint system (CRS) firmly. To free the belt again, fully retract the belt
and then pull the belt out once more. ( →P. 57)
