■Security feature
If a door is not opened within approximately 30 seconds after the vehicle is unlocked, the
security feature automatically locks the vehicle again.
■Welcome light illumination control
The front position, tail and license plate lights automatically turn on at night when the
doors are unlocked using the entry function or wireless remote control if the light switch
is in the “AUTO” position.
■When the door cannot be locked by the lock sensor on the upper part of the door han-
dle (vehicles with entry function)

If an attempt to lock the doors is made when a door is not fully closed, a buzzer sounds
continuously for 5 seconds. Fully close the door to stop the buzzer, and lock the vehicle
once more.

time.

When trouble arises
GS450h_300h_OM_OM30F00E_(EE)
■Emergency tire puncture repair kit
●The sealant has a limited lifespan. The expiry date is shown on the bottle. The sealant
should be replaced before the expiry date. Contact any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional 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 dealer or repairer, or another duly qualified and
equipped professional.
●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.
■If the tire is inflated to more than the recommended level
Disconnect the hose from the valve.
Disconnect the hose from the valve, remove the air release cap from the hose and then
reconnect the hose.
Turn the compressor switch on and wait for several seconds, and then turn it off. Check
that the air pressure indicator shows the recommended level. ( →P. 5 7 5 )
If the air pressure is lower than the recommended level, turn the compressor switch on
again and repeat the inflation procedure until the recommended pressure is reached. Install the air release cap to the end of the
hose and push the protrusion on the air
release cap into the tire valve to let some air
out.
