 Position the lap belt as low as possi- ble over the hips.
 Adjust the position of the seatback.
Sit up straight and well back in the
seat.
 Do not twist the seat belt.
■Child seat belt usage
The seat belts of your vehicle were princi-
pally designed for persons of adult size.
●Use a child restraint system appropriate

●When the child becomes large enough to
properly wear the vehicle’s seat belt, fol-
low the instructions regarding seat belt
usage. ( P.26)

a personalized seat be lt extender is avail-
able from your Lexus dealer free of charge.
WARNING
■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 be lt 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 do es not function cor-
rectly, immediately contact your Lexus
dealer.
●Replace the seat a ssembly, including
the belts, if your vehicle has been
involved in a serious accident, even if
there is no obvious damage.
●Do not attempt to install, remove,
modify, disassemble or dispose of the

carried out by your Lexus dealer. Inap-
propriate handling may lead to incor-
rect operation.
Correct use of the seat belts
WARNING
■Using a seat belt extender

extender.

371-1. For safe use
1
For safety and security
WARNING
●The SRS front passenger airbag also
deploys with considerable force, and
can cause death or serious injury
especially if the front passenger is very
close to the airbag. The front passen-
ger seat should be as far from the air-
bag as possible with the seatback
adjusted, so the front passenger sits
upright.
●Improperly seated and/or restrained
infants and children can be killed or
seriously injured by a deploying airbag.
An infant or child who is too small to
use a seat belt should be properly
secured using a child restraint system.
Lexus strongly recommends that all
infants and children be placed in the
rear seats of the vehicle and properly
restrained. The rear seats are safer for
infants and children than the front pas-
senger seat. (
P.45)
●Do not sit on the edge of the seat or
lean against the dashboard.
●Do not allow a child to stand in front of
the SRS front passenger airbag unit or
sit on the knees of a front passenger.
●Do not allow the front seat occupants
to hold items on their knees.
●Do not lean against the door, the roof
side rail or the front, side and rear pil-
lars.
●Do not allow anyone to kneel on the
passenger seats toward the door or
put their head or hands outside the
vehicle.
●Do not attach anything to or lean any-
thing against areas such as the dash-
board, steering wheel pad and lower
portion of the instrument panel.
These items can become projectiles
when the SRS driver, front passenger
and knee airbags deploy.

441-1. For safe use
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.
■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 engine.
●Do not leave the vehicle with the
engine running 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 engine running in an
area with snow build-up, or where it is
snowing. If snowbanks build up around
the vehicle while the engine is running,
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.

Riding with children
Observe the following precautions
when children are in the vehicle.
Use a child restraint system appro-
priate for the child , until the child
becomes large enough to properly
wear the vehicle’s seat belt.
 It is recommended that children
sit in the rear seats to avoid acci-
dental contact with the shift lever,
wiper switch, etc.
 Use the rear door child-protector
lock or the window lock switch to
avoid children opening the door
while driving or operating the
power window accidentally.
( P.102, 146)
 Do not let small children operate
equipment which may catch or
pinch body parts, such as the
power window, hood, back door,
seats etc.
WARNING
■When children are in the vehicle
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 panoramic moon roof,
or other features of the vehicle. In addi-
tion, heat build-up or extremely cold
temperatures inside the vehicle can be
fatal to children.
Child restraint systems
Before installing a child restraint
system in the vehicle, there are pre-
cautions that need to be observed,
different types of child restraint sys-
tems, as well as installation meth-
ods, etc., written in this manual.
Use a child restraint system when
riding with a small child that cannot
properly use a seat belt. For the
child’s safety, install the child
restraint system to a second-row
seat. Be sure to follow the installa-
tion method that is in the operation
manual enclosed with the restraint
system.

Points to remember

501-2. Child safety
A child restraint system for a small
child or baby must itself be properly
restrained on the seat with the lap por-
tion of the lap/shoulder belt.
■Installing child restraint system
using a seat belt (child restraint
lock function belt)
Install the child restraint system in
accordance to the operation manual
enclosed with the child restraint sys-
tem.
■Rear-facing  Infant seat/con-
vertible seat
1 Adjust the rear seat
If there is a gap between the child seat and
the seatback, adjust the seatback angle
until good contact is achieved.
2Place the child restraint system on
the rear seat facing the rear of the
vehicle.
3 Run the seat belt through the child
restraint system and insert the plate
WARNING
●Do 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 ai rbags deploy even
if the child is seated in the child
restraint system. It is dangerous if the
SRS side airbags and curtain shield air-
bags inflate, and the impact could
cause death or serious injury to the
child.
●When a booster seat is installed,
always ensure that th e shoulder belt is
positioned across the center of the
child’s shoulder. The belt should be
kept away from the child’s neck, but
not so that it could fall off the child’s
shoulder.
●Use child restraint system suitable to
the age and size of the child and install
it to the rear seat.
●If the driver’s seat interferes with the
child restraint system and prevents it
from being attached correctly, attach
the child restraint system to the
right-hand rear seat.
●Adjust the front passenger seat so that
it does not interfere with the child
restraint system.
