WARNING
●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 com-
pleted, 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 procedure is
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 opera-
tion 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 oper-ated for a long period of time. Do not operate the compressor contin-
uously for more than 40 minutes.
●Parts of the repair kit become hot
during operation. Be careful han- dling the repair kit during and after operation. Do not touch the metal
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 may
prevent the SRS air bag from oper- ating properly.
■Driving to spread the liquid seal-ant evenly
Observe the following precautions to
reduce the risk of accidents.
Failing to do so may result in a loss of vehicle control and cause 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 through the steer- ing 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 130 kPa (1.3
kgf/cm2 or bar, 19 psi) or less, the tire may be severely damaged.
NOTICE
■When performing an emergency repair
●Perform the emergency repair with-
out 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 emer- gency tire puncture repair kit may not be possible.
●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 malfunc- tion may occur.
●Make sure the sealant bottle of the repair kit is in a vertical position. The repair kit does not operate
properly when it is laid.

8-2. Steps to take in an emergency
When trouble arises
order from which they were con-
nected.
10 Close the positive (+) battery
terminal cover.
Once the EV system starts, have
the vehicle inspected at any autho-
rized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer as soon as possible.
■Starting the EV system when the 12-volt battery is discharged
The EV system cannot be started by push-starting.
■To prevent 12-volt battery dis-charge
●Turn off the headlights, the air condi-tioning system, the audio system, etc.
while the EV system is off.
●Turn off any unnecessary electrical
components when the vehicle is run- ning at a low speed for an extended period, such as in heavy traffic.
■Charging the 12-volt battery
The electricity stored in the 12-volt bat- tery 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 vehi-cle is left for a long time, the 12-volt bat-
tery may discharge, and the EV system may be unable to start. (The 12-volt bat-tery recharges automatically while the
EV system is operating.)
■When the 12-volt battery is removed or discharged
●Information stored in the ECU is cleared. When the 12-volt battery is depleted, have the vehicle inspected
at any authorized Toyota retailer or Toyota authorized repairer, or any reli-able repairer.
●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 EV 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 bat-
tery, 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 battery.
●If the 12-volt battery discharges, 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.
●The power back door (if equipped) must be initialized. ( P.198)
■When replacing the 12-volt battery
●Use a 12-volt battery that conforms to European regulations.
●Use a 12-volt battery that the case size is same as the previous one (LN1), 20 hour rate capacity (20HR) is
equivalent (45Ah) or greater, and per- formance rating (CCA) is equivalent (286A) or greater.
• If the sizes differ, the 12-volt battery cannot be properly secured.• If an improper 12-volt battery is used,
battery performance may decrease and the EV system may not be able to restart.
• If the 20 hour rate capacity is low, even if the time period where the vehi-cle is not used is a short time, the 12-
volt battery may discharge and EV system may not be able to start.

WARNING
■To prevent an accident or injury 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 motor compartment may be very hot.
●Keep hands and clothing (espe-cially a tie, a scarf or a muffler)
away from the fan. Failure to do so may cause the hands or clothing to be caught, resulting in serious
injury.
●Do not loosen the coolant reservoir
cap while the EV system and radia- tor are hot. High temperature steam or coolant could spray out.
NOTICE
■When adding coolant
Add coolant slowly after the EV sys-
tem has cooled down sufficiently. Adding cool coolant to a hot EV sys-tem too quickly can cause damage to
the EV system.
■To prevent damage to the cooling
system
Observe the following precautions:
●Avoid contaminating the coolant
with foreign matter (such as sand or dust, etc.).
●Do not use water or any other cool-ant when refilling coolant. Also, do not use any additive agents for the
coolant.
