CAUTION
The repair kit may overheat if operated for a long period of time. Do not
operate the repair kit continuously for more than 40 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.

STEP 2

530 5-2. Steps to take in an emergency
PRIUS +_OM_OM47821E_(EE)Start the hybrid system and turn the air conditioning system
on to check that the radiator cooling fans operate and to
check for coolant leaks from the radiator or hoses.
The fans operate when the air conditioning system is turned on
immediately after a cold start. Confirm that the fans are 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.
(The fans may not operate in freezing temperatures.)
If the fans are not operating:
Stop the hybrid system immediately and contact any autho-
rized Toyota dealer or repairer, or another duly qualified and
equipped professional.
If the fans are operating:
Have the vehicle inspected at the nearest any authorized
Toyota dealer or repairer, or another duly qualified and
equipped professional.
