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.
■Rear-facing — Infant seat/convert-
ible seat
1 Adjust the seatback
If there is a gap between the child seat and
the seatback, adjust the seatback until
good contact is achieved.
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 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 seri-
ous 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.
When using a child restraint sys-
tem on a rear seat
WARNING
■When installing a child restraint sys-
tem
Observe the following precautions. Fail-
ure to do so may result in death or seri-
ous injury.
●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.
●Do not allow the child to lean his/her
head or any part of his/her body
against the door or th e area of the seat,
rear pillars or roof side rails from which
the SRS curtain shield airbag deploys
even if the child is seated in the child
restraint system. It is dangerous if the
SRS curtain shield airbag inflates, and
the impact could cause death or seri-
ous injury to the child.

■Automatic Collision Notification
In case of either airbag deployment or
severe rear-end collision, the system is
designed to automatically call the
response center. The responding agent
receives the vehicle’s location and
attempts to speak with the vehicle
occupants to assess the level of emer-
gency. If the occupants are unable to
communicate, the ag ent automatically
treats the call as an emergency, con-
tacts the nearest emergency services
provider to describe the situation, and
requests that assistance be sent to the
location.
■Stolen Vehicle Location
If your vehicle is stolen, Safety Connect
can work with local authorities to assist
them in locating and recovering the
vehicle. After filing a police report, call
the Safety Connect response center at
1-800-25-LEXUS (1-800-255-
3987) and follow the prompts for
Safety Connect to initiate this service.
In addition to assisting law enforce-
ment with recovery of a stolen vehicle,
Safety-Connect-equipped vehicle
location data may, under certain cir-
cumstances, be shared with third par-
ties to locate your vehicle. Further
information is available at Lexus.com.
■Emergency Assistance Button
(“SOS”)
In the event of an emergency on the
road, push the “SOS” button to reach
the Safety Connect response center.
The answering agent will determine
your vehicle’s location, assess the
emergency, and dispatch the neces-
sary assistance required.
If you accidentally press the “SOS” button,
tell the response-center agent that you are
not experiencing an emergency.
■Enhanced Roadside Assistance
Enhanced Roadside Assistance adds
GPS data to the already included war-
ranty- based Lexus roadside service.
Subscribers can press the “SOS” but-
ton to reach a Safety Connect
response-center agent, who can help
with a wide range of needs, such as:
towing, flat tire, fuel delivery, etc. For a

Maintenance and care
Remove dirt and dust using a vac-
uum cleaner. Wipe dirty surfaces
with a cloth dampened with luke-
warm water.
If dirt cannot be removed, wipe it off
with a soft cloth dampened with
neutral detergent diluted to approx-
imately 1%. Wring out any excess
water from the cloth and thoroughly
wipe off remaining traces of deter-
gent and water.
■Shampooing the carpets
There are several commercial foaming-type
cleaners available. Use a sponge or brush
to apply the foam. Rub in overlapping cir-
cles. Do not use water. Wipe dirty surfaces
and let them dry. Excellent results are
obtained by keeping the carpet as dry as
possible.
■Handling the seat belts
Clean with mild soap and lukewarm water
using a cloth or spon ge. Also check the
belts periodically for excessive wear, fraying
or cuts.
■Front side windows with UV protective
coating (vehicles with UV protective
coating)
The front side windows have UV protective
coating. To prevent any damage to the UV
protective coating, observe the following:
●If the windows are dirty, gently wipe them
with a cloth soaked in water or lukewarm
water as soon as possible.
●If the windows are very dirty, do not open
and close them repeatedly.Cleaning and protecting the
vehicle interior
Perform cleaning in a manner
appropriate to each component
and its material.
Protecting the vehicle interior
WARNING
■Water in the vehicle
●Do not splash or spill liquid in the vehi-
cle, such as on the floor, in the hybrid
battery (traction battery) air vents, and
in the luggage compartment.
Doing so may cause the hybrid battery,
electrical components, etc. to mal-
function or catch fire.
●Do not get any of the SRS components
or wiring in the vehicle interior wet.
( P.32)

the airbags to deploy or not function
properly, resulting in death or serious
injury.

windshield, obstructin g the driver’s view
and leading to an accident, resulting in
death or serious injury.

detergent, as they may discolor the
vehicle interior or cause streaks or
damage to painted surfaces:
• Non-seat portions: Organic sub- stances such as benzene or gasoline,
alkaline or acidic solutions, dye, and
bleach

Boîtier électronique de coussins gonflables
Votre véhicule est équipé de COUSSINS GONFLABLES INTELLIGENTS
(ADVANCED AIRBAGS) conçus selon les normes de sécurité américaines applicables
aux véhicules à moteur (FMVSS208). Le boît ier électronique de coussins gonflables
(ECU) utilise les informations reçues des capteu rs, etc. détaillés dans le schéma ci-dessus
de composition du système pour commander le déploiement des coussins gonflables. Ces
informations comprennent des in formations sur la gravité de la collision et les occupants.
Le déploiement rapide des coussins gonflables est obtenu au moyen d’une réaction
chimique dans les dispositifs pyrotechniques, qui produit un gaz inoffensif permettant
d’amortir le mouvement des occupants.
