7-2. Steps to take in an emergency

If you have a flat tire (vehicles without

spare tire)

Your vehicle is not equipped with a spare tire, but instead is
equipped with an emergency tire puncture repair kit.
A puncture caused by a nail or screw passing through the tire
tread can be repaired temporarily using the emergency tire
puncture repair kit. (The kit contains a bottle of sealant. The
sealant can be used only once to temporarily repair one tire
without removing the nail or screw from the tire.) After temporar-
ily repairing the tire with the kit, have the tire repaired or
replaced by any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.

WARNING

■

If you have a flat tire

Do not continue driving with a flat tire.
Driving even a short distance with a flat tire can damage the tire and the
wheel beyond repair, which could result in an accident.

●

Stop the vehicle in a safe place on a hard, flat surface.

●

Set the parking brake.

●

Shift the shift position to P.

●

Stop the hybrid system.

●

Turn on the emergency flashers.

●

Check the degree of the tire damage.

A tire should only be repaired
with the emergency tire punc-
ture repair kit if the damage is
caused by a nail or screw pass-
ing through the tire tread.

• Do not remove the nail or

screw from the tire. Remov-
ing the object may widen the
opening and make emer-
gency repair with the repair
kit impossible.

• To avoid sealant leakage, move the vehicle until the area of the

puncture, if known, is positioned at the top of the tire.

■

A flat tire that cannot be repaired with the emergency tire puncture repair
kit

In the following cases, the tire cannot be repaired with the emergency tire
puncture repair kit. Contact any authorized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer.

●

When the tire is damaged due to driving without sufficient air pressure

●

When there are any cracks or damage at any location on the tire, such as on
the side wall, except the tread

●

When the tire is visibly separated from the wheel

●

When the cut or damage to the tread is 4 mm (0.16 in.) long or more

●

When the wheel is damaged

●

When two or more tires have been punctured

●

When more than one sharp objects such as nails or screws have passed
through the tread on a single tire

●

When the sealant has expired

Inflate the tire until the specified air pressure is reached.

The sealant will be injected
and the pressure will spike to
300 kPa (3.0 kgf/cm

or bar, 44

psi) or 400 kPa (4.0 kgf/cm

bar, 58 psi), 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 out-
side temperature). If the tire 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 any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
If the tire inflation pressure exceeds the specified air pressure, let out
some air to adjust the tire inflation pressure. (



P. 612, 665)

With the compressor switch off, pull out the power plug from the
power outlet socket and then disconnect the hose from the valve on
the tire.

Some sealant may leak when the hose is removed.

Install the valve cap onto the valve of the emergency repaired tire.

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.

7-2. Steps to take in an emergency

Temporarily store the bottle in the luggage compartment while it is
connected to the compressor.
To spread the liquid sealant evenly within the tire, immediately drive
safely for about 5 km (3 miles) below 80 km/h (50 mph).

After driving, stop your vehicle
in a safe place on a hard, flat
surface and reconnect the
repair kit.

Remove the air release cap from
the hose before reconnecting the
hose.

Turn the compressor switch on and wait for several seconds, then
turn it off. Check the tire inflation pressure.

If the tire inflation pressure is
under 130 kPa (1.3 kgf/cm

or bar, 19 psi): The puncture
cannot be repaired. Contact
any authorized Toyota
retailer or Toyota authorized
repairer, or any reliable
repairer.
If the tire inflation pressure is
130 kPa (1.3 kgf/cm

or bar,

19 psi) or higher, but less
