■ Emergency tire puncture repair kit
● 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 needs to be purchased, contact any authorized Toyota 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.
● The sealant has a limited lifespan. The expiry date is shown on the bottle.
The bottle of sealant should be replaced with a new bottle before the expiry
date. Contact any authorized Toyota dealer or repairer, or another duly qual-
ified and equipped professional for replacement.
● 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 to check or to adjust the tire pressure.

WARNING
■ Do not drive the vehicle with 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.
Driving with a flat tire may cause a circumferential groove on the side wall.
In such a case, the tire may explode when using a repair kit.
■ Caution while driving
● Store the repair kit in the luggage compartment.
Injuries may result in the event of an accident or sudden braking.
●The repair kit is exclusively only for your vehicle.
Do not use repair kit on other vehicles, which could lead to an accident
causing death or serious injury.
●Do not use repair kit for tires that are different size than the original ones,
or for any other purpose. If the tires have not been completely repaired, it
could lead to an accident causing death or serious injury.
■ Precautions for use of the sealant
● Ingesting the sealant is hazardous to your health. If you ingest sealant,
consume as much water as possible, and then immediately consult a doc-
tor.
● If sealant gets in eyes or adheres to skin, immediately wash it off with

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 immediately after
the vehicle has been driven.
After the vehicle has been driven, the wheels and the area around the
brakes may be extremely hot. Touching these areas with hands, feet or
other body parts may result in burns.
●Connect the valve and hose securely with the tire installed on the vehicle.
If the hose is not properly connected to the valve, air leakage 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 splatter when the
hose is disconnected or some air is let out of the tire.
●Follow the operation procedure to repair the tire. If the procedures not fol-
lowed, 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. If 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 time. Do not
operate the repair kit continuously 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 metal part connect-
ing the bottle and the compressor. It will be extremely hot.

■ Starting the hybrid system when the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
■ To prevent 12-volt battery discharge
● Turn off the headlights and the audio system while the hybrid system is off.
● Turn off any unnecessary electrical components when the vehicle is running
at a low speed for an extended period, such as in heavy traffic.
■ When the 12-volt battery is removed or discharged
●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 recon-
necting the 12-volt battery.

●If the 12-volt battery discharges while the shift position is in P, it may not be
possible to shift the shift position to other positions. In this case, the vehicle
cannot be towed without lifting both front wheels because the front wheels
will be locked. (→P. 380)
● When the 12-volt battery is reconnected, start the hybrid system and con-
firm that the shift position can be changed to each position using the shift
position indicator.
■ Charging the 12-volt battery
The electricity stored in the 12-volt battery will discharge gradually even when
the vehicle is not in use, due to natural discharge and the draining effects of
certain electrical appliances. If the vehicle is left for a long time, the 12-volt
battery may discharge, and the hybrid system may be unable to start. (The
12-volt battery recharges automatically while the hybrid system is operating.)
WARNING
■ Avoiding 12-volt battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flam-
mable 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 “+” 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.
