sound of a fuel evaporation leakage
check and, it does not indicate a mal-
function.
A wide variety of non-genuine spare

WARNING
■General precautions while driving
Driving under the influence: Never drive
your vehicle when under the influence of
alcohol or drugs that have impaired your
ability to operate your vehicle. Alcohol
and certain drugs delay reaction time,
impair judgment and reduce coordina-
tion, which could lead to an accident that
could result in death or serious injury.
Defensive driving: Always drive defen-
sively. Anticipate mistakes that other
drivers or pedestrians might make and
be ready to avoid accidents.
Driver distraction: Always give your full
attention to driving. Anything that dis-
tracts the driver, such as adjusting con-
trols, talking on a cellular phone or
reading can result in a collision with
resulting death or serious injury to you,
your occupants or others.
■General precaution regarding chil-
dren’s safety
Never leave children unattended in the
vehicle, and never allow children to have
or use the key.
Children may be able to start the vehicle
or shift the vehicle into neutral. There is
also a danger that children may injure
themselves by playing with the windows,
the moon roof, or other features of the
vehicle. In addition, heat build-up or
extremely cold temperatures inside the
vehicle can be fatal to children.

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:
 Hybrid system
 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.
High voltage parts and cables on the
hybrid vehicles emit approximately the
same amount of electromagnetic
waves as the conventional gasoline
powered vehicles or home electronic
appliances despite of their electro-
magnetic shielding.
Unwanted noise may occur in the
reception of the mobile two-way radio.
The vehicle is equipped with sophisti- cated computers that will record cer-
tain data, such as:
The recorded data varies according to
the vehicle grade level and options
with which it is equipped.
These computers do not record con-
versations or sounds, and only record
images outside of the vehicle in certain
situations.
• Engine speed/Elect
ric 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
• Images from the front camera (avail- able only when certain safety sys-
tems are activated, which varies
depending on the vehicle specifica-
tions).
 Data Transmission
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.
Lexus will not disclose the recorded data to
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 official request by the police, a court of law or a government
agency

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 bottom-
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 hybrid system stopped and
the shift lever in P, fully depress each
pedal to the floor to make sure it does
not interfere with the floor mat.

■Pregnant women
Obtain medical advice and wear the seat
belt in the proper way. ( P.27)
Women who are pregnant should posi-
tion the lap belt as low as possible over
the hips in the same manner as other
occupants, extending the shoulder belt
completely over the shoulder and avoid-
ing belt contact with the rounding of the
abdominal area.
If the seat belt is not worn properly, not
only the pregnant woman, but also the
fetus could suffer death or serious injury
as a result of sudden braking or a colli-
sion.

■Seat belt damage and wear
●Do not damage the seat belts by allow-
ing the belt, plate, or buckle to be
jammed in the door.
●Inspect the seat belt system periodi-
cally. Check for cuts, fraying, and loose
parts. Do not use a damaged seat belt
until it is replaced. Damaged seat belts
cannot protect an occupant from
death or serious injury.
●Ensure that the belt and plate are
locked and the belt is not twisted.
If the seat belt does not function cor-
rectly, immediately contact your Lexus
dealer.
●Replace the seat assembly, including
the belts, if your vehicle has been
involved in a serious accident, even if
there’s no obvious damage.

carried out by your Lexus dealer. Inap-
propriate handling may lead to incor-
rect operation.

For safety and security
Exhaust gas precautions
Harmful substances to the human
body are contained in exhaust
gases if inhaled.
WARNING
Exhaust gases contain harmful carbon
monoxide (CO), which is colorless and
odorless. Observe the following precau-
tions.
Failure to do so may cause exhaust gases
enter the vehicle and may lead to an
accident caused by light-headedness, or
may lead to death or a serious health
hazard.
■Important points while driving
●Keep the back door closed.
●If you smell exhaust gases in the vehi-
cle even when the back door is closed,
open the windows and have the vehi-
cle inspected at your Lexus dealer as
soon as possible.
■When parking
●If the vehicle is in a poorly ventilated
area or a closed area, such as a
garage, stop the hybrid system.
●Do not leave the vehicle with the
hybrid system on for a long time. If
such a situation cannot be avoided,
park the vehicle in an open space and
ensure that exhaust fumes do not enter
the vehicle interior.
●Do not leave the hybrid system operat-
ing in an area with snow build-up, or
where it is snowing. If snowbanks build
up around the vehicle while the hybrid
system is operating, exhaust gases
may collect and enter the vehicle.
■Exhaust pipe
The exhaust system needs to be checked
periodically. If there is a hole or crack
caused by corrosion, damage to a joint
or abnormal exhaust noise, be sure to
have the vehicle inspected and repaired
by your Lexus dealer.
