impact sensors (front door), side impact se nsors (front), side impact sensors (rear),
driver’s seat position sensor, driver’s seat belt buckle switch, front passenger occupant
classification system, “AIR BAG ON” indicat or light, “AIR BAG OFF” indicator light,
front passenger’s seat belt buckle switch, seat belt pretensioner assemblies, airbags,
interconnecting wiring and power sources. (P. 43)
■Front passenger detection sensor, seat belt reminder and warning buzzer
If luggage is placed on the front passenger seat, the front passenger detection sensor
may cause the warning light to flash and the warning buzzer to sound even if a passenger
is not sitting in the seat.
■If the malfunction indicator lamp comes on while driving
First check the following:
●Is the fuel tank empty?
If it is, fill the fu el tank immediately.
●Is the fuel tank cap loose?
If it is, tighten it securely.
The light will go off after several driving trips.
If the light does not go off even after severa l trips, contact your Lexus dealer as soon as
possible.
■Electric power steering system warning light (warning buzzer)
When the battery charge becomes insufficien t or the voltage temporarily drops, the
electric power steering system warning li ght may come on and the warning buzzer may
sound.
■When the tire pressure warning light comes on
Check the tire inflation pressure and adjust to the appropriate level. Initializing the tire
pressure warning system will not turn off the tire pressure warning light.
■The tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on due to natural causes such as natural air
leaks and tire inflation pressure changes caus ed by temperature. In this case, adjusting
the tire inflation pressure will turn off the warning light (after a few minutes).
■When a tire is replaced with a spare tire
The compact spare tire is not equipped with a tire pressure warning valve and transmit-
ter. If a tire goes flat, the tire pressure warning light will not turn off even though the flat
tire has been replaced with the spare tire.

WARNING
■Caution while driving
Observe the following precautions.
Failure to do so may cause an accident.
●The emergency tire puncture repair kit is made exclusively for your vehicle. Do not
use it on other vehicles.
●Do not use the emergency tire puncture repa ir kit for tires that are a different size
than the specified ones or for any other pu rpose. Doing so may cause the tires to not
be repaired properly.
■Precautions for use of the sealant
●Ingesting the sealant is hazardous to your health. If you ingest sealant, consume as
much water as possible, and then immediately consult a doctor.
●If sealant gets in eyes or adheres to skin, immediately wash it off with water. If discom-
fort persists, consult a doctor.
■When fixing the flat tire
●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 dis-
connected or some air is let out of the tire.
●Follow the operation procedure to repair the tire. If the procedures 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 repair operation immedi-
ately.
●The repair kit may over heat if operated for a long peri od of time. Do not operate the
repair kit continuously for more than 35 minutes.
●Parts of the repair kit become hot during oper ation. Be careful handling the repair kit
during and after operation. Do not touch th e metal part connecting the bottle and the
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 prevent the SRS air bag from operating properly.
