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 y
our vehicle.
All specifications provided in this manual are current at the time of printing. How -
ever, because of the Lexus policy of contin ua
l product improvement, we reserve the
right to make changes at any time without notice.
Depending on specifications, the vehicle show n in
the illustration may differ from
your vehicle in terms of color and equipment.
Accessories, spare parts and modification of your Lexus
A wide variety of non-genuine spare parts and accessories for Lexus vehicles are
currently available in the market. You should know that Toyota does not warrant
these products and is not responsible for 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 regula tions. In addition, damage or perfor-
mance problems resulting from the modi fication may not be
covered under war-
ranty.
Installation of a mobile two-way radio system
As the installation of a mobile two-way ra dio system in your vehicle could affect
electronic systems such as the hybrid system, multiport fuel injection system/
sequential multiport fuel injection system , cruise control system, vehicle dynamics
integrated management, SRS airbag system and seat belt pretensioner system, be
sure to check with your Lexus dealer for precautionary measures or special instruc -
tions regarding installation.
High voltage parts and cables on the hybr i
d vehicles emit approximately the same
amount of electromagnetic waves as the conventional gasoline powered vehicles or
home electronic appliances despite of their electromagnetic shielding.
Unwanted noise may occur in the reception of the mobile two-way radio.

xvii
Scrapping of your Lexus
The SRS airbag and seat belt pretensioner devices in your Lexus contain explosive
chemicals. If the vehicle is scrapped with the airbags and seat belt pretensioners left
as they are, this may cause an accident such as fire. Be sure to have the systems of
the SRS airbag and seat belt pretensioner removed and disposed of by a qualified
service shop or by your Lexus deal er before you scrap your vehicle.
Smart access system with push-button start
Users of any electrical medical devices such as implanted pacemakers should con -
sult the manufacturer of the device for information about its operation under the
influence
of radio waves. Radio waves could have unexpected effects on the opera -
tion of such me dical de
vices. (P. 1 2 , 14 )
Leak detection pump (for the U.S.A. and Canada)
This pump performs fuel evaporation leakage check. This check is conducted sev -
eral hours after the hybrid system is turn ed of
f. You may hear a sound coming from
underneath the trunk for several minutes, however this does not indicate a malfunc-
tion.

1-3. Opening, closing and locking the doors and trunk
1
Before driving
■Closing the front doors from outside with the inside lock button set in the locked
position
The door cannot be locked if the power switch is in “ACC” or “IG-ON” mode, or
the e
lectronic key is left in the vehicle. (However, depending on the key's location,
the system may not be able to detect it. In these instances the door lock protection
function will not operate properly.)
■Using the mechanical key
The doors can also be locked and unlocked with the mechanical key. ( P.
4 6 9 )
■Customization
Settings (e.g. unlocking function using a key) can be changed. (P. 5 0 0 )
CAUTION
■To prevent an accident
Observe the following precautions while driving the vehicle. 
Failing to do so may result in a door openin g and an occupant falling out, resulting in
death or serious injury.
●Always use a seat belt.
●Always lock all doors.
●Ensure that all doors are properly closed.
●Do not pull the inside handle of the front door while driving.
●Set the rear door child protector locks when children are seated in the rear seat.

CAUTION
■Reclining adjustment
Do not recline the seat more than necessary when the vehicle is in motion, to
reduce the risk of sliding under the lap belt.
If the seat is too reclined during an accide nt, the lap belt may slide past the hips and
apply restraint forces directly to the abdomen or your neck may contact the shoul-
der belt, increasing the risk of death or serious injury.
■When adjusting the front passenger’s seat from the driver’s seat
Wait until a passenger is seated or have go tten off the front passenger’s seat before
operating the switch to avoid injuring the passenger.

1-4. Adjustable components
Seat belts
Make sure that all occupants are wearing their seat belts before driving the
vehicle.
■Correct use of the seat belts
Extend the shoulder belt so
that it comes fully over the
shoulder
, but does not come
into contact with the neck or
slide off the shoulder.
Position the lap belt as low as
possible over the hips.
Adjust the position of the
seatback. Sit up straight and
w
ell back in the seat.
Do not twist the seat belt.
■ F
astening and releasing the seat belt
Fastening the belt
Push the tab into the buckle until
a clicking sound is heard.
Releasing the belt
Press the release button.
Release button

1-4. Adjustable components
1
Before driving
Seat belt comfort guide (outboard rear seats)
If the shoulder belt fits close to a
person’s neck, slide the seat belt
comfort guide forward.
Seat belt pretensioners (front and outboard rear seats)
The pretensioner helps the seat
belt to quickly restrain the occu-
pant by retracting the seat belt
when the v
ehicle is subjected to
certain types of severe frontal colli -
sion.
The pretensioner may not activate
in the event of a minor frontal
impact, a side impact or a rear
impact.
■ Adjusting the height of the belt (front seats)
Up
Down
Move the height adjuster up and
down as needed until you hear a
click.

44
1-4. Adjustable components
Pre-collision seat belts (front seats of vehicles with pre-collision system)
When the pre-collision sensor detects an obstacle and determines that a
collision is unavoidable, the seat belts lessen collision injury by retracting
the slack in the front seat belts befo re the collision, thus restraining the
driver and passenger at an earlier stage. 
The seat belts will also operate in the event of sudden braking. ( P. 1 6 7 )
■Emergency locking retractor (ELR)
The retractor will lock the belt during a sudd e
n stop or on impact. It may also lock if
you lean forward too quickly. A slow, easy motion will allow the belt to extend, and
you can move around fully.
■Automatic locking retractor (ALR)
When a passenger's shoulder bel
t 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. 8 7 )
■Pregnant women
Obtain medical advice and wear the seat belt
in the proper way. ( P. 4 2 )
Women who are pregnant should position
the lap belt as low as possible over the hips in
the same manner as other occupants. Extend
the shoulder belt completely over the shoul-
der and position the belt across the chest.
Avoid belt contact over the rounding of the
abdominal area.
If the seat belt is not worn properly, not only a
pregnant woman, but also the fetus could suf-
fer death or serious injury as a result of sud-
den braking or a collision.
