WARNING
QFront passenger occupant classifica-
tion system precautions
Observe the following precautions
regarding the front passenger occupant
classification system.
Failure to do so may cause death or seri-
ous injury.
OWear the seat belt properly.
OMake sure the front passenger’s seat
belt plate has not been left inserted
into the buckle befo re someone sits in
the front passenger seat.

381-1. For safe use
WARNING
OMake sure the “PASSENGER AIR
BAG OFF” indicator light is not illumi-
nated when using the seat belt
extender for the front passenger seat.
If the “PASSENGER AIR BAG OFF”
indicator light is illuminated, discon-
nect the extender tongue from the
seat belt buckle, and reconnect the
seat belt. Reconnect the seat belt
extender after making sure the “PAS-
SENGER AIR BAG ON” indicator
light is illuminated. If you use the seat
belt extender while the “PASSENGER
AIR BAG OFF” indicator light is illu-
minated, the SRS airbags for the front
passenger will not activate, which
could cause death or serious injury in
the event of a collision.
ODo not apply a heavy load to the front
passenger seat or equipment (e.g.
seatback pocket).
ODo not put weight on the front passen-
ger seat by putting your hands or feet
on the front passenger seat seatback
from the rear passenger seat.
ODo not let a rear passenger lift the
front passenger seat with their feet or
press on the seatback with their legs.
ODo not put objects under the front pas-
senger seat.
ODo not recline the front passenger
seatback so far that it touches a rear
seat. This may cause the “PASSEN-
GER AIR BAG OFF” indicator light to
be illuminated, which indicates that the
SRS airbags for the front passenger
will not activate in the event of a severe
accident. If the seatback touches the
rear seat, return the seatback to a
position where it does not touch the
rear seat. Keep the front passenger
seatback as upright as possible when
the vehicle is moving. Reclining the
seatback excessively may lessen the
effectiveness of the seat belt system.
OIf an adult sits in the front passenger
seat, the “PASSENGER AIR BAG
ON” indicator light is illuminated. If the
“PASSENGER AIR BAG OFF” indi-
cator is illuminated, ask the passenger
to sit up straight, well back in the seat,
feet on the floor, and with the seat belt
worn correctly. If the “PASSENGER
AIR BAG OFF” indicator still remains
illuminated, either ask the passenger
to move to the rear seat, or if that is not
possible, move the front passenger
seat fully rearward.
OWhen it is unavoidable to install a for-
ward-facing child restraint system on
the front passenger seat, install the
child restraint system on the front pas-
senger seat in the proper order.
(  P.45)
ODo not modify or remove the front
seats.
ODo not kick the front passenger seat or
subject it to severe impact. Otherwise,
the SRS warning light may come on to
indicate a malfunction of the front pas-
senger occupant classification system.
In this case, contact your Lexus dealer
immediately.
OChild restraint systems installed on the
rear seat should not contact the front
seatbacks.
ODo not use a seat accessory, such as a
cushion and seat cover, that covers the
seat cushion surface.
ODo not modify or replace the uphol-
stery of the front seat.
ODo not place anything between the
console box and front passenger seat.
Otherwise, the system may not detect
the front passenger properly, leading
to improper operation of the airbags.

his/her physique and posture.
*2: In the event the front passenger is wearing a seat belt.
*3: In the event the front passenger does not wear a seat belt.
*4: For some children, child in seat, child in boos ter seat or child in convertible seat, the sys-
tem may not recognize him/her as a child. Factors which may affect this can be the phy-
sique or posture.

Exhaust gas precautions
Harmful substance to the human
body is included in exhaust gases if
inhaled.
WARNING
Exhaust gases include 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.
QImportant points while driving
OKeep the trunk lid closed.
OIf you smell exhaust gases in the vehi-
cle even when the trunk lid is closed,
open the windows and have the vehi-
cle inspected at your Lexus dealer as
soon as possible.
QWhen parking
OIf the vehicle is in a poorly ventilated
area or a closed area, such as a
garage, stop the hybrid system.
ODo not leave the vehicle with the
hybrid system operating 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.
ODo not leave the hybrid system oper-
ating 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.
QExhaust 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.

461-2. Child safety
Adjust the lumbar support to the
lowest position.
 Adjust the pelvic support
* to the
lowest position.
 If the head restrain t interferes with
the child restraint system installation
and the head restraint can be
removed, remove the head
restraint. Otherwise, put the head
restraint in the upper most position.
*: If equipped
WARNING
QWhen using a child restraint system
Observe the following precautions.
Failure to do so may result in death or
serious injury.
ONever install a rear-facing child
restraint system on the front passen-
ger seat even if the “PASSENGER
AIR BAG OFF” indicator light is illu-
minated. In the event of an accident,
the force of the rapid inflation of the
front passenger airbag can cause
death or serious injury to the child if
the rear-facing child restraint system is
installed on the front passenger seat.
OA forward-facing child restraint sys-
tem may be installed on the front pas-
senger seat only when it is
unavoidable. A child restraint system
that requires a top tether strap should
not be used in the front passenger seat
since there is no top tether strap
anchor for the front passenger seat.
OA forward-facing child restraint sys-
tem may be installed on the front pas-
senger seat only when it is
unavoidable. When installing a for-
ward-facing child restraint system on
the front passenger seat, adjust the
seatback angle to the most upright
position, move the seat to the rearmost
position, and raise the seat to the
upper most position, even if the “PAS-
SENGER AIR BAG OFF” indicator
light is illuminated.
ODo not allow the child to lean his/her
head or any part of his/her body
against the door or the area of the seat,
front or rear pillars, or roof side rails
from which the SRS side airbags or
SRS curtain shield airbags deploy even
if the child is seated in the child
restraint system. It is dangerous if the
SRS side and curtain shield airbags
inflate, and the impact could cause
death or serious injury to the child.

QRunning out of fuel
When the vehicle has run out of fuel and the
hybrid system cannot be started, refuel the
vehicle with at least enough gasoline to
make the low fuel level warning light
(  P.367) go off. If there is only a small
amount of fuel, the hybrid system may not
be able to start. (The standard amount of fuel is about 2.4 gal. [9.0 L, 2.0 Imp.gal.],
when the vehicle is on a level surface. This
value may vary when the vehicle is on a
slope. Add extra fuel when the vehicle is
inclined.)
QElectromagnetic waves
OHigh voltage parts and cables on hybrid
vehicles incorporate electromagnetic
Hybrid system precautions
Take care when handling the hybrid system, as it is a high voltage system
(about 650 V at maximum) as well as
contains parts that become extremely
hot when the hybrid system is operating. Obey the warning labels attached to
the vehicle.
