WARNING
■Child restraint precautions
●For effective protection in automobile ac cidents and sudden stops, a child must be
properly restrained, using a seat belt or child restraint system depending on the age
and size of the child. Holding a child in your arms is not a substitute for a child restraint
system. In an accident, the child can be crushed against the windshield, or between
you and the vehicle’s interior.
●Lexus strongly urges the use of a proper child restraint system that conforms to the
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.
●Never use a rear-facing child restraint syst em on the front passenger seat when the
airbag manual on-off switch is on. ( P. 54)
In the event of an accident, the force of the rapid inflation of the front passenger air-
bag can cause death or serious injury to the child.
●A forward-facing child restraint system ma y be installed on the front passenger seat
only when it is unavoidable. A child restra int system that requires a top strap should
not be used in the front passenger seat sinc e there is no top strap anchor for the front
passenger seat. Adjust the seatback as up right as possible and always move the seat
as far back as possible because the front passenger airbag could inflate with consid-
erable speed and force. Otherwise, the ch ild may be killed or seriously injured.
●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 and rear pillars or roof side rails from which the SRS
side airbags or SRS curtain shield airbags depl oy even if the child is seated in the child
restraint system. It is dangerous if the SR S side airbags and curtain shield airbags
inflate, and the impact could cause death or serious injury to the child.
●Make sure you have complied with all installation instructions provided by the child
restraint manufacturer and that the system is properly secured. If it is not secured
properly, it may cause death or serious inju ry to the child in the event of a sudden
stop, sudden swerve or accident.
■When children are in the vehicle
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 othe r serious injuries that could result in death.
If this occurs and the buckle cannot be unfa stened, scissors should be used to cut the
belt.
■When the child restraint system is not in use
●Keep the child restraint system properly secure d on the seat even if it is not in use. Do
not store the child restraint system un secured in the passenger compartment.
●If it is necessary to detach the child rest raint system, remove it from the vehicle or
store it securely in the trunk. If a head restraint was removed when installing a child
restraint system, always install the head restraint before driving. This will prevent it
from injuring passengers in the event of a sudden stop, sudden swerve or accident.

5187-2. Steps to take in an emergency
GS450h_300h_OM_OM30F92E_(EE) Attach the air release cap to the end
of the hose.
If the air release cap is not attached, the
sealant may leak and the vehicle may
get dirty.
Temporarily store the bottle in the trunk while it is connected to the compres-
sor.
To spread the liquid sealant evenly within the tire, immediately drive safely for
about 5 km (3 miles) below 80 km/h (50 mph).
After driving for about 5 km
(3 miles), stop your vehicle in a safe
place on a hard, flat surface and
remove the air release cap from the
hose before reconnecting the repair
kit.
Turn the compressor switch on and
wait for several seconds, and then
turn it off. Check the tire inflation
pressure.
If the tire inflation pressure is
under 130 kPa (1.3 kgf/cm 2
or
bar, 19 psi): The puncture cannot
be repaired. Contact any autho-
rized Lexus retailer or Lexus
authorized repairer, or any reli-
able repairer.
If the tire inflation pressure is 130 kPa (1.3 kgf/cm 2
or bar, 19 psi) or higher,
but less than the recommended level: Proceed to step .
If the tire inflation pressure is the recommended level: Proceed to step .

When trouble arises
GS450h_300h_OM_OM30F92E_(EE) Turn the compressor switch on to infl
ate the tire until the recommended tire
inflation pressure is reached. Drive for about 5 km (3 miles) and then per form
step .
Attach the air release cap to the end
of the hose.
If the air release cap is not attached, the
sealant may leak and the vehicle may
get dirty.
Store the bottle in the trunk while it is connected to the compressor.
Taking precautions to avoid sudden braking, sudden acceleration and sharp
turns, drive carefully at under 80 km /h (50 mph) to any authorized Lexus
retailer or Lexus authorized repairer, or any reliable repairer that is less than
100 km (62 miles) away for tire repair or replacement.
■Emergency tire puncture repair kit
●The sealant has a limited lifespa n. The expiry date is shown on the bottle. The sealant
should be replaced before the expiry date. Contact any authorized Lexus retailer or
Lexus authorized repairer, or any reliable repairer for replacement.
●The sealant stored in the emergency tire puncture repair kit can be used only once to
temporarily repair a single tire. If the sealant has been used and need to be purchased,
contact any authorized Lexus retailer or Lexus authorized repairer, or any reliable
repairer.
●The sealant can be used when the outside temperature is from -40 C (-40 F) to
60 C (140 F).
●The repair kit is exclusively designed for size and type of tires originally installed on your
vehicle. Do not use it for tires that a different size than the original ones, or for any other
purposes.
●If the sealant gets on your clothes, it may stain.
●If the sealant adheres to a wheel or the surface of the vehicle body, the stain may not be
removable if it is not cleaned at once. Immediately wipe away the sealant with a wet
cloth.
●During operation of the repair kit, a loud operation noise is produced. This does not
indicate a malfunction.
●Do not use the emergency tire puncture repair kit to check or to adjust the tire pres-
sure.
