WARNING

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 operating properly.

Check the specified tire inflation pressure.

Tire inflation pressure is specified on the label as shown.

Start the hybrid system.

To inject the sealant and inflate the tire, turn the compressor switch on.

WARNING

Observe the following precautions.

●

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. If you notice any cracks
or deformation in the tire, turn off the compressor switch and stop the repair
operation immediately.

●

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

●

Parts of the emergency tire puncture repair kit become hot during operation. Be
careful when handling it during and after operation.

ouble arises

WARNING

●

Do not touch the metal connecting parts of the bottle and compressor while being
used or immediately after, as they will be extremely hot.

Inflate the tire until the specified pressure is reached.

The sealant will be injected and the pressure will spike to between 44 psi (300
kPa, 3.0 kgf/cm

or bar) and 58 psi (400 kPa, 4.0 kgf/cm

or bar), then gradually

decrease.

The air pressure gauge will display the actual tire inflation 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 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 your Lexus dealer.
If the tire inflation pressure exceeds the specified level, let out some air to adjust
the tire inflation pressure.

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

Some sealant may leak when the hose is removed.

660

WARNING

After inflation of the tire has completed, the sealant may splatter when the hose is
disconnected or some air is let out of the tire.

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 dirty the interior of the
vehicle or ones clothes.

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 safety for
about 3 miles (5 km) below 50 mph (80 km/h).

WARNING

Observe the following precautions when driving to spread the sealant evenly.

●

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 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

or bar) or below, this may indicate severe tire damage.

After driving, stop your vehicle in a safe place on a hard, flat surface and
reconnect the emergency tire puncture 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 below 19 psi (130 kPa, 1.3 kgf/cm

or bar): The

puncture cannot be repaired. Contact your Lexus dealer.

If the tire inflation pressure is between 19 psi (130 kPa, 1.3 kgf/cm

or bar) and a

point below the specified level: The tire can be repaired. Proceed to step

If the tire inflation pressure is at the specified level: Proceed to step

Even if the tire inflation pressure is at the recommended level, the tire pressure
warning light may come on/flash.

Turn the compressor switch on to inflate the tire until the specified tire inflation
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 dirty the interior of the
vehicle or ones clothes.

Store the bottle in the luggage compartment while it is connected to the
compressor.

Taking precautions to avoid sudden braking, sudden acceleration and sharp
turns, drive carefully at under 50 mph (80 km/h) to your Lexus dealer that is
less than 100 km (62 miles) away for tire repair or replacement.

When having the tire repaired or replaced, make sure to tell the Lexus dealer that the
sealant is injected.
After using the emergency tire puncture repair kit, have the vehicle inspected and the
tire pressure warning valve and transmitter replaced by your Lexus dealer. Otherwise
the tire inflation pressure may not be able to be measured correctly.

Decreasing the tire inflation pressure when a tire is overinflated

Disconnect the hose from the valve.

Install the air release cap to the end of the hose and push the protrusion on the
air release cap into the valve to let some air out.

Disconnect the hose from the valve, remove the air release cap from the hose
and then reconnect the hose.

Turn the compressor switch on for a few seconds and then turn it off and check
the tire inflation pressure.

If the air pressure is lower than the specified level, turn the compressor switch on again
and repeat the inflation procedure until the specified pressure is reached.

Precautions for when you have a flat tire (vehicles with run-flat tires)

Your vehicle is not equipped with a spare tire, but instead you can continue driving
the vehicle with run-flat tires even if any tire goes flat. In this case, slow down and
drive with extra caution.
Take your vehicle to the nearest Lexus dealer or authorized tire dealer as soon as
possible if any tire goes flat.
The vehicle can be driven for a maximum of 50 miles (80 km) at a speed below
50 mph (80 km/h) after the tire pressure warning light comes on.

A run-flat tire has a

mark on the side wall.

INFORMATION

■

In some conditions (such as at high temperatures)

You cannot continue driving for up to 50 miles (80 km).

NOTICE

■

When replacing the tires

When removing or fitting the wheels, tires or the tire pressure warning valve and
transmitter, contact your Lexus dealer as the tire pressure warning valve and transmitter
may be damaged if not handled correctly.

■

When driving over bumps

If a vehicle has a flat tire, the vehicle height will be lower than usual. Ensure that nothing
strikes the bottom of the vehicle.

■

To avoid damage to the tire pressure warning valves and transmitters

When a tire is repaired with liquid sealants, the tire pressure warning valve and transmit-
ter may not operate properly. If a liquid sealant is used, contact your Lexus dealer or
other qualified service shop as soon as possible. Make sure to replace the tire pressure
warning valve and transmitter when replacing the tire.

battery, you can jump start your vehicle by following the steps below.

INFORMATION

The hybrid system cannot be started by push-starting.

WARNING

■

Avoiding 12-volt battery fires or explosions

Observe the following precautions to prevent accidentally igniting the flammable gas that
may be emitted from the 12-volt battery:

●

Make sure each jumper cable is connected to the correct terminal and that it is not
unintentionally in contact with any other than the intended terminal.

●

Do not allow the other end of the jumper cable connected to the “+” terminal to come
into contact with any other parts or metal surfaces in the area, such as brackets or
unpainted metal.

●

Do not allow the + and - clamps of the jumper cables to come into contact with each
other.

●

Do not smoke, use matches, cigarette lighters or allow open flame near the 12-volt
battery.

■

12-volt battery precautions

The 12-volt battery contains poisonous and corrosive acidic electrolyte, while related
parts contain lead and lead compounds. Observe the following precautions when han-
dling the 12-volt battery:
