and may cause an injury. Do not drive
with the hood raised, as doing so may
block the driver’s vision, possibly caus-
ing an accident.●
Do not forcibly push down the hood.
As the popped up hood cannot be
lowered by hand, doing so may deform
the hood or cause an injury.●
If the Pop Up Hood has operated, have
it replaced by your Lexus dealer. If the

Make sure to close the hood before
driving, as the system may not operate
properly if the hood is not fully closed.
●
Make sure that all 4 tires are of the
specified size and inflated to the speci-
fied tire pressure. If tires of a different
size are used, the system may not
operate properly.
●
If something has hit the area around
the front bumper, the sensors may be
damaged even if the Pop Up Hood has
not operated. Have the vehicle
inspected by your Lexus dealer.
●
Do not remove or repair the parts or
wiring of the Pop Up Hood, as doing
so may cause accidental operation or
prevent the system from operating
properly. If repair or replacement is
necessary, contact your Lexus dealer. ●
Do not remove such components as
the front bumper, hood or suspension,
or replace them with non-genuine
parts, as doing so may prevent the sys-
tem from operating properly. ●
Do not install anything to the front
bumper or hood, as doing so may pre-
vent the sensors fr om detecting an
impact correctly and prevent the sys-
tem from operating properly. ●
Do not close the hood with force or
apply load to the lifters, as doing so
may damage the lifters and prevent the
system from operating properly. ●
Do not modify the suspension, as
changes made to the vehicle height

The laws of all 50 states of the U.S.A.
as well as Canada now require the use
of child restraint systems.
 Prioritize and observe the warn-
ings, as well as the laws and regula-Riding with children Observe the following precautions
when children are in the vehicle.

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.

( → P.99, 141)
 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 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 rear seat. Be sure to fol-
low the installation method that is in
the operation manual enclosed with
the restraint system.

LS500_OM_OM50F54U_(U) 1
For safety and security
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.WARNING●
A forward-facing child restraint system
may be installed on the front passen-
ger 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.●
A forward-facing child restraint system
may be installed on the front passen-
ger seat only when it is unavoidable.
When installing a forward-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 “AIR BAG OFF” indicator light is
illuminated.
●
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 and curtain shield airbags
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 passe nger seat so that
it does not interfere with the child
restraint system.

Child restraint LATCH anchors
LATCH anchors are provided for the
outboard rear seat. (Buttons displaying
the location of the anchors are
attached to the seats.)
■
Installation with LATCH system
Install the child restraint system in WARNING●
Do not allow children to play with the
seat belt. If the seat belt becomes
twisted around a child’s neck, it may
lead to choking or other serious inju-
ries that could result in death.
If this occurs and the buckle cannot be
unfastened, scissors should be used to
cut the belt.●
Ensure that the belt and plate are
securely locked and the seat belt is not
twisted.●
Shake the child restraint system left
and right, and forward and backward
to ensure that it has been securely
installed.●
After securing a child restraint system,
never adjust the seat.●
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.●
Follow all installation instructions pro-
vided by the child restraint system
manufacturer.
●
When securing some types of child
restraint systems in rear seats, it may
not be possible to properly use the
seat belts in position s next to the child
restraint without inte rfering with it or
affecting seat belt effectiveness. Be
sure your seat belt fits snugly across
your shoulder and low on your hips. If it
does not, or if it interferes with the
child restraint, move to a different posi-
tion. Failure to do so may result in
death or serious injury. ●
When installing a child restraint system
in the rear center se at, adjust both seat
cushions to the same position and
align both seatbacks at the same
angle. Otherwise, the child restraint
system cannot be securely restrained
and this may cause death or serious
injuries in the event of sudden braking,
sudden swerving or an accident. ■
When installing a booster seat
To prevent the belt from going into ALR
lock mode, do not fully extend the shoul-
der belt. ALR mode causes the belt to
tighten only. This could cause injury or
discomfort to the child. ( → P.26)■
Do not use a seat belt extender
If a seat belt extender is used when
installing a child restra int system, the seat
belt will not securely hold the child
restraint system, which could cause
death or serious injury to the child or
other passengers in the event of sudden
braking, sudden swerving or an accident.
