CAUTION
When fixing the flat tire
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 procedures not fol-
lowed, the sealant may spray out.
Keep back from the tire while it is being repaired, as there is a chance of it
bursting while the repair operation is being performed. If you notice any
cracks or deformation of the tire, turn off the compressor switch and stop
the repair operation immediately.
The repair kit may overheat if operated for a long period of time. Do not
operate the repair kit continuously for more than 60 minutes.
Parts of the repair kit become hot during operation. Be careful handling the
repair kit during and after operation. Do not touch the metal part connect-
ing 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 indicated. 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
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in a loss of vehicle control and cause death or
serious injury.
Drive the vehicle carefully at a low speed. Be especially careful when turn-
ing and cornering.
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 the tire inflation pressure is 130 kPa (1.3
kgf/cm
2 or bar, 19 psi) or less, the tire may be severely damaged.

Add coolant if necessary.
Water can be used in an emer-
gency if coolant is unavailable.
Start the engine and turn the air conditioning system on to
check that the radiator cooling fan operates and to check for
coolant leaks from the radiator or hoses.
The fan operates when the air conditioning system is turned on
immediately after a cold start. Confirm that the fan is operating by
checking the fan sound and air flow. If it is difficult to check these,
turn the air conditioning system on and off repeatedly.

Toyota dealer or repairer, or another duly qualified and
equipped professional.
