WARNING
■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 wi th 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 ha s 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 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 repair 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 10 minutes.
●Parts of the kit become hot during operatio n. Be careful handling the kit during and
after operation.
●Do not attach the vehicle speed warning stic ker 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.
■Driving to spread the 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 infl ation pressure is 130 kPa (1.3 kgf/cm2 or bar, 19 psi) or below, this may indi cate severe tire damage.

■Run-flat tires (A “RFT” or “DSST” mark is molded on the sidewall)
Take your vehicle to the nearest
Lexus dealer or authorized tire
dealer as soon as possible if any tire
goes flat.
The vehicle can be driven for a maxi- mum of 300 km (186 miles) at a
speed below 60 km/h (37 mph)
after the tire pressure warning light comes on. ( P. 578)
■In some conditions (such as at high temperatures)
You cannot continue driving for up to 300 km (186 miles).
■For the detailed informat ion on run-flat tires
See the tire warranty booklet.
If you have a flat tire (vehicles with run-flat tires)
Your vehicle is not equipped with a sp are tire, but instead you can continue
driving the vehicle with run-flat tires even if any tire goes flat.In this case, slow
down and drive with extra caution.
NOTICE
■When replacing the tires
When removing or fitting the wheels, tires or the tire pressure warning valve and trans-
mitter, contact any authorized Lexus retailer or Lexus authorized repairer, or any reli- able repairer as the tire pressure warning valve and transmitter may be damaged if not
handled correctly.
■When driving over bumps
If a vehicle has a flat tire, the vehicle height will be lower than usual. Ensure that nothing
strikes the bottom of the vehicle.
■To avoid damage to the tire pressure warning valves and transmitters
When a tire is repaired with liquid sealants , the tire pressure warning valve and trans-
mitter may not operate properly. If a liqui d sealant is used, contact any authorized
Lexus retailer or Lexus authoriz ed repairer, or any reliable repairer or other qualified service shop as soon as possible. Make sure to replace the tire pressure warning valve
and transmitter when replacing the tire. ( P. 526)
