cle interior or cause streaks or damage to painted surfaces:
• Non-seat portions: Organic substances such as benzene or gasoline,
alkaline or acidic solutions, dye, and bleach
• Seats: Alkaline or acidic solutions, such as thinner, benzene, and alco-
hol
Do not use polish wax or polish cleaner. The instrument panel’s or other

leather surfaces:
Remove any dust or dirt from leather surfaces immediately.
Do not expose the vehicle to direct sunlight for extended periods of time.
Park the vehicle in the shade, especially during summer.
Do not place items made of vinyl, plastic, or containing wax on the uphol-
stery, as they may stick to the leather surface if the vehicle interior heats
up significantly.
Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio system may be damaged if water comes
into contact with electrical components such as the audio system above or
under the floor of the vehicle. Water may also cause the body to rust.

In the following cases, the tire cannot be repaired with the emergency tire
puncture repair kit. Contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
When the tire is damaged due to driving without sufficient air pressure
When the tire lost air pressure due to a crack or damage in the tire sidewall
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 there is more than one hole or cut in the damaged tire
When the sealant has expired
Emergency tire puncture repair kit
The sealant has a limited lifespan. The expiry date is shown on the bottle.
The sealant should be replaced before the expiry date. Contact any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional for replacement.
The sealant stored in the emergency tire puncture repair kit can be used only
once to temporarily repair a single tire. If the sealant has been used and
need to be purchased, contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
The sealant can be used when the outside temperature is from -40 C (-40
F) to 60 C (140 F).
The repair kit is exclusively designed for size and type of tires originally
installed on your vehicle. Do not use it for tires that a different size than the
original ones, or for any other purposes.
If the sealant gets on your clothes, it may stain.
If the sealant adheres to a wheel or the surface of the vehicle body, the stain
may not be removable if it is not cleaned at once. Immediately wipe away
the sealant with a wet cloth.
During operation of the repair kit, a loud operation noise is produced. This
does not indicate a malfunction.
Do not use the emergency tire puncture repair kit to check or to adjust the
tire pressure.

CAUTION
Driving to spread the liquid 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 tire inflation pressure is 130 kPa (1.3 kgf/cm
2
or bar, 19 psi) or less, the tire may be severely damaged.
NOTICE
When performing an emergency repair
Perform the emergency repair without removing the nail or screw that has
punctured the tread of the tire. If the object that has punctured the tire is
removed, repair by the emergency tire puncture repair kit may not be pos-
sible.
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 malfunction may
occur.

When trouble arises

When recharging or replacing the 12-volt battery
For vehicles with an alarm: make sure that the key is not inside the vehicle
when recharging or replacing the 12-volt battery. The key may be locked in
the vehicle if the alarm is activated. (P. 99)
In some cases, it may not be possible to unlock the doors using the smart
entry & start system when the 12-volt battery is discharged. Use the wire-
less remote control or the mechanical key to lock or unlock the doors.
The hybrid system may not start on the first attempt after the 12-volt battery
has recharged but will start normally after the second attempt. This is not a
malfunction.
The power switch mode is memorized by the vehicle. When the 12-volt bat-
tery is reconnected, the system will return to the mode it was in before the
12-volt battery was discharged. Before disconnecting the 12-volt battery,
turn the power switch off.
If you are unsure what mode the power switch was in before the 12-volt
battery discharged, be especially careful when reconnecting the 12-volt bat-
tery.
CAUTION
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 termi-
nal.
Do not allow the other end of the jumper cable connected to the “+” termi-
nal 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.

CAUTION
When inspecting under the hood of your vehicle
Observe the following precautions.
Failure to do so may result in serious injury such as burns.
If steam is seen coming from under the hood, do not open the hood until
the steam has subsided. The engine compartment may be very hot.
After the hybrid system has been turned off, check that the indicator on
the power switch and the “READY” indicator are off.
When the hybrid system is operating, the gasoline engine may automati-
cally start, or the cooling fan may suddenly operate even if the gasoline
engine stops. Do not touch or approach rotating parts such as the fan,
which may lead to fingers or clothing (especially a tie, a scarf or a muf-
fler) getting caught, resulting in serious injury.
Do not loosen the coolant inlet cap or
the coolant reservoir caps while the
hybrid system and radiator are hot.
High temperature steam or coolant
could spray out.
