WARNING
■Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly
when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire inflation p ressure
label (tire and load information label). (If your vehicle has t ires of a dif-
ferent size than the size indicated on the vehicle placard or t ire inflation
pressure label [tire and load information label], you should de termine
the proper tire inflation p ressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS -tire pressure warning system) that
illuminates a low tire pressure telltale (tire pressure warning light) when
one or more of your tires is significantly under-inflated. Acco rdingly,
when the low tire pressure telltale (tire pressure warning ligh t) illumi-
nates, you should stop and check your tires as soon as possible , and
inflate them to the proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire tread lif e, and may
affect the vehicle’s handling and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a sub-
stitute for proper tire maintenance, and it is the driver’s res ponsibility to
maintain correct tire pressure, even if under-inflation has not reached
the level to trigger illumination of the TPMS low tire pressure telltale (tire pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warn-
ing system) malfunction indicato r to indicate when the system is not
operating properly. The TPMS (tire pressure warning system) mal func-
tion indicator is combined with the low tire pressure telltale (tire pressure
warning light). When the system detects a malfunction, the tell tale will
flash for approximately one minute and then remain continuously illumi-
nated. This sequence will continue upon subsequent vehicle star t-ups
as long as the malfunction exists . When the malfunction indicator is illu-
minated, the system may not be able to detect or signal low tir e pres-
sure as intended.
TPMS (tire pressure warning system) malfunctions may occur for a vari-
ety of reasons, including the installation of replacement or alternate tires
or wheels on the vehicle that prevent the TPMS (tire pressure w arning
system) from functioning properly. Always check the TPMS (tire pres-
sure warning system) malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the replacement or alter-
nate tires and wheels allow the TPMS (tire pressure warning system) to
continue to function properly.

PRIUS PRIME_OM_OM47C77U_(U)
To inject the sealant and inflate
the tire, turn the compressor
switch on.
Inflate the tire until the specified air pressure is reached.The sealant will be injected
and the pressure will spike to
between 44 psi (300 kPa,
3.0 kgf/cm
2 or bar) and
58 psi (400 kPa, 4.0 kgf/cm2
or bar), then gradually
decrease.
The air pressure gauge will
display the actual tire infla-
tion pressure about 1 to 5
minutes after the switch is
turned on.
• Turn the compressor switch off and then check the tire
inflation pressure. Being
careful not to over inflate,
check and repeat the inflation
procedure until the specified
tire inflation pressure is
reached.
• The tire can be inflated for about 5 to 20 minutes (depending on
the outside temperature). If the t ire inflation pressure is still lower
than the specified point after inflation for 25 minutes, the tire is
too damaged to be repaired. Turn the compressor switch off and
contact your Toyota dealer.
• If the tire inflation pressure exceeds the specified air press ure, let
out some air to adjust the tire inflation pressure. ( P. 691, 725)

Turn the compressor switch on and wait for several seconds, then
turn it off. Check the t ire inflation pressure.
If the tire inflation pressure is
under 19 psi (130 kPa,
1.3 kgf/cm
2 or bar): The
puncture cannot be repaired.
Contact your Toyota dealer.
If the tire inflation pressure is
19 psi (130 kPa, 1.3 kgf/cm
2
or bar) or higher, but less
than the specified air pres-
sure: Proceed to step .
If the tire inflation pressure is the specified air pressure ( P. 725):
Proceed to step .
Turn the compressor switch on to inflate the tire until the spe cified
air pressure is reached. Drive for about 3 miles (5 km) and then
perform step .
Attach the air release cap to the
end of the hose.
If the air release cap is not
attached, the sealant may leak
and the vehicle may get dirty.
Store the bottle in the luggage compartment while it is connect ed to
the compressor.
Taking precautions to avoid sudden braking, sudden acceleration
and sharp turns, drive carefully at under 50 mph (80 km/h) to the
nearest Toyota dealer that is less than 62 miles (100 km) away fo r
tire repair or replacement.
When having the tire repaired or replaced, make sure to tell th e Toyota
dealer that the sealant is injected.

When trouble arises
■If the tire is inflated to more than the specified air pressure
Disconnect the hose from the valve.
Disconnect the hose from the valv e, remove the air release cap from
the hose and then reconnect the hose.
Turn the compressor switch on and wait for several seconds, and then
turn it off. Check that the air pressure indicator shows the sp ecified air
pressure. ( P. 725)
If the air pressure is under the designated pressure, turn the compres-
sor switch on again and repeat the inflation procedure until th e speci-
fied air pressure is reached.
■The valve of a tire that has been repaired
After a tire is repaired with the emergency tire puncture repai r kit, the
valve should be replaced.
■After a tire is repaired with the emergency tire puncture repai r kit
●The tire pressure warning valve and transmitter should be replaced.
●Even if the tire inflation pressure is at the recommended level, the tire
pressure warning light may come on/flash.
■Note for checking the emergency tire puncture repair kit
Check the sealant expiry date occasionally.
The expiry date is shown on the bottle. Do not use sealant whos e expiry
date has already passed. Otherwise, repairs conducted using the emer-
gency tire puncture repair kit may not be performed properly. Install the air release cap to the end of
the hose and push the protrusion on
the air release cap into the tire valve
to let some air out.

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 p si
(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.
