WARNING
■When the electric power steering 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 extre mely
heavy. When steering wheel operations are heavier than usual, grip the
steering wheel firmly and operate it using more force than usua l.
■
If the tire pressure warning light comes on
Be sure to observe the following precautions. 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 emergency tire puncture repair kit: If the tire p ressure
warning light comes on even after tire inflation pressure adjus tment, it
is probable that you have a flat tire. Check the tires. If a ti re is flat,
repair the flat tire by using emergency tire puncture repair ki t.
●Vehicles with spare tire: If the tire pressure warning light co mes on
even after tire inflation pressure adjustment, it is probable t hat 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 Toyota deal er.
●Avoid abrupt maneuvering and braking. If the vehicle tires dete riorate,
you could lose control of the steering wheel or the brakes.
■If a blowout or sudden air leakage should occur
The tire pressure warning system may not activate immediately.

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 immediate ly
after the vehicle has been driven.
After the vehicle has been driven, the wheels and the area arou nd the
brakes may be extremely hot. Touching these areas with hands, f eet or
other body parts may result in burns.
●Connect the valve and hose securely with the tire installed on the vehi-
cle. If the hose is not properly connected to the valve, air le akage may
occur as 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 spla tter when
the hose is disconnec ted or some air is let out of the tire.
●Follow the operation procedure to repair the tire. If the proce dures not
followed, 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. I f 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 ti me. Do not
operate the repair kit continuous ly 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 met al 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 indicated. If the sticker is attached to an area where an SRS
airbag is located, such as the pad of the steering wheel, it ma y prevent
the SRS airbag from operating properly.

When trouble arises
WARNING
■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 ca use 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 throu gh 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 19 psi (130 kPa, 1.3 kgf/cm
2 or bar) or less, the tire may be severely dam-
aged.
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 obje ct may
widen the opening and disenable e mergency 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 sa nd at the
side of the road. If the repair kit vacuums up dust etc., a mal function
may occur.
■Precautions for the emergency tire puncture repair kit
●The repair kit power source should be 12 V DC suitable for vehi cle
use. Do not connect the repa ir kit to any other source.
●If fuel splatters on the repair kit, the repair kit may deterio rate. Take
care not to allow fuel to contact it.
●Place the repair kit in a storage to prevent it from being exposed to dirt
or water.
●Store the repair kit in the luggage compartment out of reach of chil-
dren.
●Do not disassemble or modify the repair kit. Do not subject par ts such
as the air pressure indicator to impacts. This may cause a malfunction.
