■When a tire is replaced with a spare
tire
Vehicles with a compact spare tire: The compact spare tire is not equipped with
a tire pressure warning valve and trans- mitter. 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. Replace the spare tire with the repaired tire and adjust the
tire inflation pressure. The tire pressure warning light will go off after a few min-utes.
Vehicles with a full-size spare tire: The spare tire is also equipped with a tire pressure warning valve and transmitter.
The tire pressure warning light will turn on if the tire inflation pressure of the spare tire is low. 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. Replace the
spare tire with the repaired tire and adjust the tire inflation pressure. The tire pressure warning light will go off after a
few minutes.
■Conditions that the tire pressure warning system may not function properly
 P. 3 3 6
WARNING
■If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact any autho-rized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer. The vehicle will become extremely unstable during braking, and the ABS
system may fail, which could cause an accident resulting in death or seri-ous injury.
■When the electric power steer-ing system warning light comes on
When the light comes on yellow, the assist to the power steering is restricted. When the light comes on
red, the assist to the power steering is lost and handling operations of the steering wheel become extremely
heavy. When steering wheel operations are heavier than usual, grip the steering
wheel firmly and operate it using more force than usual.
■If the tire pressure warning light comes on
Be sure to observe the following pre-
cautions. Failure to do so could cause a loss of vehicle control and result in death or
serious injury.
●Stop your vehicle in a safe place as
soon as possible. Adjust the tire inflation pressure immediately.
●Vehicles with a compact spare tire and full-size spare tire: If the tire pressure warning light comes on
even after tire inflation pressure adjustment, it is probable that you have a flat tire. Check the tires. If a
tire is flat, change it with the spare tire and have the flat tire repaired by the nearest any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●Vehicles with emergency tire punc-ture repair kit: If the tire pressure warning light comes on even after
tire inflation pressure adjustment, it is probable that you have a flat tire. Check the tires. If a tire is flat, repair
the flat tire by using emergency tire puncture repair kit.
●Avoid abrupt maneuvering and braking.If the vehicle tires deteriorate, you
could lose control of the steering wheel or the brakes.

7-2. Steps to take in an emergency
WARNING
●Keep back from the tire while it is
being repaired, as there is a chance
of it bursting while the repair opera-
tion is being performed. If you
notice any cracks or deformation of
the tire, turn (off) the compres-
sor switch and stop the repair oper-
ation immediately.
●The repair kit may overheat if oper- ated for a long period of time. Do
not operate the repair kit continu- ously for more than 40 minutes.
●Parts of the repair kit become hot during operation. Be careful when handling the repair kit during and
after operation. Do not touch the metal part around the connecting area between the bottle and com-
pressor. 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 airbag from oper-
ating properly.
●To avoid risk of burst or severe
leakage, do not drop or damage the bottle. Visually inspect the bottle before use. Do not use a bottle with
shock, crack, scratch, leakage or any other damage. In such case, immediately replace.
■Driving to spread the liquid seal-
ant 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
turning and cornering.
●If the vehicle does not drive straight or you feel a pull through the steer-ing 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/cm2 or bar, 19 psi) or less, the tire may be severely damaged.
NOTICE
■When performing an emergency repair
●A tire should only be repaired with
the emergency tire puncture repair kit if the damage is caused by a sharp object such as nail or screw
passing through the tire tread. Do not remove the sharp object from the tire. Removing the object
may widen the opening and disena- ble emergency repair with the repair kit.
●The repair kit is not waterproof. Make sure that the repair kit is not
exposed to water, such as when it is being used in the rain.
●Do not put the repair kit directly onto dusty ground such as sand at the side of the road. If the repair kit
vacuums up dust etc., a malfunc- tion may occur.
●Do not turn the bottle upside down when using it, as doing so may cause damage to the compressor.
■Precautions for the emergency tire puncture repair kit
●The repair kit power source should be 12 V DC suitable for vehicle use. Do not connect the repair kit to any
other source.
