Front passenger occupant classification system precautions ●
Do not recline the front passeng er seatback so far that it touches a rear seat. This may
cause the “AIR BAG OFF” indicator light to be illuminated, whic h indicates that the
SRS airbags for th e front passenger will no t activate in the even t 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 effec-
tiveness of the seat belt system. ●
If an adult sits in the fron t passenger seat , the “AIR BAG ON” indicator light is illumi-
nated. If the “AIR BAG OFF” indicator 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 “AIR BAG OFF” indicator still remain s illuminated, either ask the passenger to
move to the rear seat, or if that is not possible, move the fron t passenger seat fully
rearward. ●
When it is unavoidable to in stall a forward-facing child re straint system on the front
passenger seat, install the ch ild restraint system on the front passenger seat in the
proper order. (  P. 60)●
Do not modify or remove the front seats. ●
Do not kick the front passenger seat or subject it to severe impact. Otherwise, the
SRS warning light may come on to indica te a malfunction of the front passenger
occupant classification system. In this cas e, contact your Lexus dealer immediately.●
Child restraint systems insta lled on the rear se at should not contact the front seat-
backs. ●
Do not use a seat accessory, such as a cushion and seat cover, that covers the seat
cushion surface. ●
Do not modify or replace the upholstery of the front seat. ●
Do not place anything between the cons ole box and front passenger seat. Other-
wise, the system may not de tect the front passenger pr operly, leading to improper
operation of the airbags. ●
Adjust the front passenger seat so that the head restraint does not touch the ceiling. If
the head restraint is left in contact with the ceiling, the system may not detect the front
passenger properly, leading to improper operation of the airbags.

RC350_RC300 AWD_RC3 00_RC F_U(OM24748U)WARNING ■
When installing a child restraint system
Observe the following when installing child re straint system to the front passenger seat
if it is unavoidable. The front passenger SR S airbag inflates with considerable speed
and force that if not observed may lead to death or serious injury to the child.●
Never install a rear-facing child restraint sy stem on the front passenger seat even if
the “AIR BAG OFF” indicator lig ht is illuminated. In the even t 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 ch ild restraint system is inst alled on the front passenger
seat. ●
A forward-facing child restraint system ma y be installed on the front passenger 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.
●
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 air-
bags 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. ●
When a booster seat is installed, always en sure that the 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 coul d fall off the child’s shoulder.●
A forward-facing child restraint system may
be installed on the front passenger seat only
when it is unavoidable. When installing a for-
ward-facing child restrain t system on the front
passenger seat, adjust the seatback to the
most upright position, move the seat to the
rearmost position, and raise the seat to the
highest position, even if the “AIR BAG OFF”
indicator light is illuminated.
If the head restraint interferes with the instal-
lation of the child re straint system, and the
head restraint can be removed, remove the
head restraint.

Automatic Collision Notification
In case of either airbag deployment or severe rear-end collision, the system is
designed to automatically call the re sponse center. The responding agent
receives the vehicle’s location and attempts to speak with the vehicle occu-
pants to assess the level of emergency. If the occupants are unable to commu-
nicate, the agent automatically treats the call as an emergency, contacts the
nearest emergency services provider to describe the situation, and requests
that assistance be sent to the location.Safety Connect LED light Indicators

RC350_RC300 AWD_RC3 00_RC F_U(OM24748U)WARNING ■
When fixing the flat tire
Observe the following precautions.
Failure to do so may result in death or serious injury.●
Stop your vehicle in a safe and flat area. ●
Do not touch the wheels or the area around the brakes immediately after the vehicle
has been driven.
After the vehicle has been driven, the wheels and the area around the brakes may be
extremely hot. Touching these areas with hands, feet or other body parts may result in
burns. ●
Connect the valve and hose securely with the tire installed on the vehicle.
• If the hose is not properly connected to the valve, air leakage may occur or sealant
may be sprayed out.
• If the hose comes off the valve while inflating the tire, there is a risk that the hose
will move abruptly due to air pressure.
• After inflation of the tire has completed, the sealant may splatter when the hose is
disconnected or some air is let out of the tire. ●
Follow the operation procedure to repair the tire. If the procedure is not followed, the
sealant may spray out. ●
Keep back from the tire while it is being re paired, as there is a chance of it bursting
while the repair operation is being performed. If you notice any cracks or deforma-
tion of the tire, turn off the compressor sw itch and stop the repa ir operation immedi-
ately. ●
The kit may overheat if operated for a long period of time. Do not operate the com-
pressor continuously for more than 35 minutes. ●
Parts of the kit become hot during operation. Be careful handling the kit during and
after operation. Do not touch the metal part around the connecting area between the
bottle and compressor. It will be extremely hot. ●
Do not attach the vehicle speed warning sticker to an area other than the one indi-
cated. If the sticker is attached to an area where an SRS airbag is located, such as the
pad of the steering wheel, it may preven t the SRS airbag from operating properly.■
Driving to spread th e liquid sealant evenly●
Drive the vehicle carefully at a low speed. Be especially careful when turning and cor-
nering. ●
If the vehicle does not drive straight or you feel a pull through the steering wheel, stop
the vehicle and check the following:
• Tire condition. The tire may have separated from the wheel.
• Tire inflation pressure. If tire inflation pressure is 19 psi (130 kPa, 1.3 kgf/cm 2
or
bar) or below, this may in dicate severe tire damage.
