7-2. Steps to take in an emergency
WARNING
●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 compres-
sor switch and stop the repair oper-
ation immediately.
●The repair kit may overheat if oper- ated for a long period of time. Do
not operate the repair kit continu- ously for more than 40 minutes.
●Parts of the repair kit become hot during operation. Be careful when handling the repair kit during and
after operation. Do not touch the metal part around the connecting area between the bottle and com-
pressor. 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 airbag from oper-
ating properly.
●To avoid risk of burst or severe
leakage, do not drop or damage the bottle. Visually inspect the bottle before use. Do not use a bottle with
shock, crack, scratch, leakage or any other damage. In such case, immediately replace.
■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
●A tire should only be repaired with
the emergency tire puncture repair kit if the damage is caused by a sharp object such as nail or screw
passing through the tire tread. Do not remove the sharp object from the tire. Removing the object
may widen the opening and disena- ble emergency repair with the repair kit.
●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.
●Do not turn the bottle upside down when using it, as doing so may cause damage to the compressor.
■Precautions for the emergency tire puncture repair kit
●The repair kit power source should be 12 V DC suitable for vehicle use. Do not connect the repair kit to any
other source.

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
p owe r swi t ch wa s i n be f or e t he 1 2- v ol t battery discharged, be especially careful when reconnecting the 12-volt
battery.
■When replacing the 12-volt battery
●Use a Central Degassing type 12-volt
battery (European Regulations).
●Use a battery that the case size is
same as the previous one, 20 hour rate capacity (20HR) is equivalent or greater, and performance rating
(CCA) is equivalent or greater. Check the label on top of the battery for the battery size and specifications (ex.
LN0, 35Ah, 264A). • If the sizes differ, the 12-volt battery cannot be properly secured.
• 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 the hybrid system may not be able to start.
●Use a ventilation type calcium battery
●Use a 12-volt battery with a handle. If a 12-volt battery without a handle is used, removal is more difficult.
●When removing the 12-volt battery:  P. 3 3 0
●After replacing, firmly attach the fol- lowing items to the exhaust hole of the
12-volt battery. • Use the exhaust hose that was attached to the 12-volt battery before
replacing and confirm that it is firmly connected to the hole section of the vehicle.
• Use the exhaust hole plug included with the 12-volt battery replaced or the one installed on the 12-volt battery
prior to the replacement. (Depending
on the 12-volt battery to be replaced, the exhaust hole may be plugged.)

●For details, consult any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
WARNING
■When removing the 12-volt bat-
tery terminals
Always remove the negative (-) termi- nal first. If the positive (+) terminal
contacts any metal in the surrounding area when the positive (+) terminal is removed, a spark may occur, leading
to a fire in addition to electrical shocks and death or serious injury.
■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:

7-2. Steps to take in an emergency
When trouble arises
1Stop the hybrid system. Set the
parking brake and shift the shift
lever to P.
2 Remove the mud, snow or sand
from around the front wheels.
3 Place wood, stones or some
other material under the front
wheels to help provide traction.
4 Restart the hybrid system.
5 Shift the shift lever to D or R and
release the parking brake. Then,
while exercising caution,
depress the accelerator pedal.
■When it is difficult to free the vehi-
cle
Press the switch to turn off TRC.
A message will be shown on the multi-
information display.
WARNING
●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 “READY”
indicator is off. When the hybrid system is operating, the gasoline engine may automatically start, or
the cooling fan may suddenly oper- ate even if the gasoline engine stops. Do not touch or approach
rotating parts such as the fan, which may lead to fingers or cloth-ing (especially a tie, a scarf or a
muffler) getting caught, resulting in serious injury.
●Do not loosen the coolant reservoir caps while the hybrid system and radiator are hot.
High temperature steam or coolant could spray out.
NOTICE
■When adding engine/power con-trol unit coolant
Add coolant slowly after the hybrid
system has cooled down sufficiently. Adding cool coolant to a hot hybrid system too quickly can cause dam-
age to the hybrid 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 any coolant additive.
If the vehicle becomes
stuck
Carry out the following proce-
dures if the tires spin or the
vehicle becomes stuck in mud,
dirt or snow:
