pressure about 1 to 5 min-
utes after the switch is turned
on.
Turn the compressor switch off and
then check the tire inflation pres-
sure. Being careful not to over
inflate, check and repeat the infla-
tion procedure unt il 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 compres-
sor switch off and contact your Toy-
ota dealer.
If the tire inflation pressure exceeds
thespecified air pressure, let out
some airto adjust the tire inflation
pressure. ( P.395, 426)
15 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.
16 Install the valve cap onto the
valve of the emergency
repaired tire.
17 Attach the air release cap to
the end of the hose.
If the air release cap is not
attached, the sealant may leak and the vehicle may get dirty.
18Temporarily store the bottle
in the luggage compartment
while it is connected to the
compressor.
19To spread the liquid sealant evenly within the tire, imme-
diately drive safely for about
3 miles (5 km) below 50 mph
(80 km/h).
20After driving, stop your vehi- cle in a safe place on a hard,
flat surface and reconnect
the repair kit.
Remove the air release cap from
the hose before reconnecting the
hose.
21Turn the compressor switch
on and wait for several sec-

When trouble arises
WARNING
●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 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
airbag from operating properly.
■Driving to spread the liquid
sealant 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 d oes not drive
straight or you feel a pull
through the steering wheel, stop
the vehicle and check the fol-
lowing.
• 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
2 or bar) or less,
the tire may be severely dam-
aged.
NOTICE
■When performing an emer-
gency repair
●A tire should only be repaired
with the emergency tire punc-
ture repair kit if the damage is
caused by a sharp object such
as nail or screw passing through
the tire tread.
Do not remove th e sharp object
from the tire. Removing the
object may widen the opening
and disenable 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 malfunction may occur.
●Make sure to stand the kit with
the bottle vertical. The kit can-
not work properly if it is laid on
its side.
■Precautions for the emer-
gency 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.
●If fuel splatters on the repair kit,
the repair kit may deteriorate.
Take care not to allow fuel to
contact it.
●Place the repair kit in a storage
to prevent it from being exposed
to dirt or water.
●Store the repair kit in the tool
tray under the d eck mat out of
reach of children.

4127-2. Steps to take in an emergency
■To prevent 12-volt battery dis-
charge
●Turn off the headlights and the
audio system while the hybrid sys-
tem is off.
●Turn off any unnecessary electri-
cal 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
●Information stored in the ECU is
cleared. When the 12-volt battery
is depleted, have the vehicle
inspected at you r Toyota dealer.
●Some systems may require initial-
ization. (P.452)
■When removing the 12-volt bat-
tery terminals
When the 12-volt battery terminals
are removed, the information stored
in the ECU is cleared. Before
removing the 12-volt battery termi-
nals, contact your Toyota dealer.
■Charging the 1 2-volt battery
The electricity stor ed in the 12-volt
battery will discharge gradually even
when the vehicle is not in use, due
to natural discharge and the drain-
ing effects of certain electrical appli-
ances. If the vehicle is left for a long
time, the 12-volt battery may dis-
charge, and the hybrid system may
be unable to start. (The 12-volt bat-
tery recharges aut omatically while
the hybrid system is operating.)
■When recharging or replacing
the 12-volt battery (vehicles
with a smart key system)
●In some cases, it may not be pos-
sible to unlock the doors using the
smart key system when the
12-volt battery is discharged. Use
the wireless remote control or the
mechanical key to lock or unlock
the doors.
●The hybrid system may not start
on the first att empt 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 memo-
rized by the vehicle. When the
12-volt battery is reconnected, the
system will return to the mode it
was in before the 12-volt battery
was discharged. Before discon-
necting 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.
■When replacing t
he 12-volt bat-
tery
●Use a 12-volt battery that con-
forms 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 (295A) or
greater.
• If the sizes differ, the 12-volt bat-
tery cannot be properly secured.
• If the 20 hour rate capacity is low,
even if the time p eriod where the
vehicle is not used is a short time,
the 12-volt battery may discharge
and the hybrid system may not be
able to start.
●For details, cons ult your Toyota
dealer.
WARNING
■When removing the 12-volt
battery terminals
Always remove the negative (-)
terminal first. If the positive (+) ter-
minal contacts any metal in the
surrounding area when the posi-
tive (+) terminal is removed, a
spark may occur, leading to a fire
in addition to ele ctrical shocks
and death or serious injury.

4167-2. Steps to take in an emergency
Toyota dealer as soon as possible.
6After stopping the hybrid sys-
tem and waiting for 5 minutes
or more, start the hybrid sys-
tem again and check for the
multi-information display.
If the message does not dis-
appear: Stop the hybrid sys-
tem and contact your Toyota
dealer.
If the message is not dis-
played: The hybrid system
temperature has dropped
and the vehicle may be
driven normally.
However, if the message appears
again frequently, contact your Toy-
ota dealer.
WARNING
■When inspecting under the
hood of your vehicle
Observe the following precau-
tions. 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 sub-
sided. The engine compart-
ment 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 auto-
matically start, or the cooling
fans 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 muffler) getting caught,
resulting in serious injury.
●Do not loosen the coolant reser-
voir caps while the hybrid sys-
tem and radiator are hot.
High temperature steam or
coolant could spray out.
NOTICE
■When adding engine/power
control 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 damage to the hybrid
system.
■To prevent damage to the
cooling system
Observe the following precau-
tions:
●Avoid contaminating the coolant
with foreign matter (such as
sand or dust etc.).
●Do not use any coolant additive.

would wear one and a half (1 - 1/2)
times as well on the government
course as a tire graded 100.
The relative performance of tires
depends upon the actual conditions
of their use. Performance may differ
significantly from the norm due to
variations in driving habits, service
practices and differences in road
characteristics and climate.
■Traction AA, A, B, C
The traction grades, from high-
est to lowest, are AA, A, B and
C, and they represent the tire’s
ability to stop on wet pavement
as measured under controlled
conditions on specified govern-
ment test surfaces of asphalt
and concrete.
A tire marked C may have poor
traction performance.
Warning: The traction grade
assigned to this tire is based on
braking (straight ahead) traction
tests and does not include corner-
ing (turning) traction.
■Temperature A, B, C
The temperature grades are A (the highest), B, and C, repre-
senting the tire’s resistance to
the generation of heat and its
ability to dissipate heat when
tested under controlled condi-
tions on a specified indoor labo-
ratory test wheel.
Sustained high temperature can
cause the material
of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure.
Grade C corresponds to a level of
performance which all passenger
car tires must meet under the Fed-
eral Motor Vehicle Safety Standard
No. 109.
Grades B and A represent higher
levels of performance on the labo-
ratory test wheel than the minimum
required by law.
Warning: The temperature grades
of a tire assume tha t it is properly
inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either sepa-
rately or in combination, can cause
heat buildup and possible tire fail-
ure.
