The laws of all 50 states of the U.S.A.

 Prioritize and observe the warn-
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 window lock switch to
avoid children operating the
power window accidentally.
( P.111)
 Do not let small children operate
equipment which may catch or
pinch body parts, such as the
power window, hood, trunk, 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 other features of the
vehicle. In addition, 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 rear seat. Be
sure to follow the installation
method that is in the operation
manual enclosed with the restraint
system.

Points to remember

411-1. For safe use
1
For safety and security
ings, as well as the laws and regula-
tions for child restraint systems.
 Use a child restraint system appro-
priate for the child until the child
becomes large enough to properly
wear the vehicle’s seat belt.
 Choose a child restraint system that
suits your vehicle and is appropriate
to the age and size of the child.
■Types of child restraint system installation methods
Confirm with the operation manual enclosed with the child restraint system about
the installation of the child restraint system.
WARNING
■When a child is riding
Observe the following precautions.
Failure to do so may result in death or
serious injury.
●For effective protection in automobile
accidents and sudden stops, a child
must be properly restrained, using a
seat belt or child restraint system
which is correctly installed. For installa-
tion details, refer to the operation man-
ual enclosed with the child restraint
system. General insta llation instruction
is provided in this manual.
●Lexus strongly urges the use of a
proper child restraint system that con-
forms to the weight and size of the
child, installed on the rear seat.
According to accident statistics, the
child is safer when properly restrained
in the rear seat than in the front seat.
●Holding a child in your or someone
else’s arms is not a substitute for a child
restraint system. In an accident, the
child can be crushe d against the wind-
shield or between the holder and the
interior of the vehicle.
■Handling the child restraint system
If the child re straint system is not prop-
erly fixed in place, the child or other pas-
sengers may be seriously injured or even
killed in the event of sudden braking, sud-
den swerving, or an accident.
●If the vehicle were to receive a strong
impact from an accident, etc., it is pos-
sible that the child restraint system has
damage that is not readily visible. In
such cases, do not reuse the restraint
system.
●Make sure you have complied with all
installation instructions provided with
the child restraint system manufac-
turer and that the system is properly
secured.
●Keep the child rest raint system prop-
erly secured on the seat even if it is not
in use. Do not store the child restraint
system unsecured in the passenger
compartment.
●If it is necessary to detach the child
restraint system, remove it from the
vehicle or store it securely in the trunk.

For safety and security
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 trunk lid closed.
●If 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.
■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 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 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.
