When trouble arises
1Open the deck board. (→P.241)
2 Take out the emergency tire
puncture repair kit. ( →P.327)
1 Remove the hose and take out
the power plug from the com-
pressor.
2 Connect the bottle to the com-
pressor.
Insert and connect the bottle straight into the compressor as shown in the illustration, and check that the claws of
the bottle are concealed in the holes.
3 Connect the hose to the bottle.
As shown in the illustration, make sure the hose is connected securely to the
WARNING
●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 acci-
dent causing death or serious injury.
■Precautions for use of the seal-ant
●Ingesting the sealant is hazardous
to your health. If you ingest sealant, consume as much water as possi-ble, and then immediately consult a
doctor.
●If sealant gets in eyes or adheres to
skin, immediately wash it off with water. If discomfort persists, consult a doctor.

WARNING
●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 prop-erly 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 procedures 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 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.

ning at a low speed for an extended
period, such as in heavy traffic.
■When the battery is removed or dis- charged
●Information stored in the ECU is cleared. When the battery is depleted, have the vehicle inspected at any
authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●Some systems may require initializa-tion. ( →P.369)
■When removing the battery termi-
nals
When the battery terminals are removed, the information stored in the
ECU is cleared. Before removing the battery terminals, contact any autho-rized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer.
■Charging the battery
The electricity stored in the battery will discharge gradually even when the vehi-
cle is not in use, due to natural dis- charge and the draining effects of certain electrical appliances. If the vehi-
cle is left for a long time, the battery may discharge, and the engine may be unable to start. (The battery recharges
automatically during driving.)
■When recharging or replacing the battery
●In some cases, it may not be possible to unlock the doors using the smart entry & start system when the battery
is discharged. Use the wireless remote control or the mechanical key to lock or unlock the doors.
●The engine may not start on the first attempt after the battery has
recharged but will start normally after the second attempt. This is not a mal-function.
●The engine switch mode is memo-rized by the vehicle. When the battery
is reconnected, the system will return to the mode it was in before the bat-tery was discharged. Before discon-
necting the battery, turn the engine
switch off. If you are unsure what mode the engine switch was in before the bat-
tery discharged, be especially careful when reconnecting the battery.
■When replacing the battery
●Use a genuine battery specifically designed for use with the Stop & Start system or a battery with equivalent
specifications to a genuine battery. If an unsupported battery is used, Stop & Start system functions may be
restricted to protect the battery. Also, battery performance may decrease and the engine may not be able to
restart. Contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer for details.
●Use a battery that conforms to Euro-pean 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. LN3, 65Ah, 600A).
• If the sizes differ, the 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 bat-tery may discharge and the engine
may not be able to start.
●Use a ventilation type calcium battery
●After replacing, firmly attach the fol- lowing items to the exhaust hole of the
battery. • Use the exhaust hose that was attached to the battery before replac-
ing and confirm that it is firmly con- nected to the hole section of the vehicle.
• Use the exhaust hole plug included with the battery replaced or the one installed on the battery prior to the
replacement. (Depending on the bat- tery to be replaced, the exhaust hole

WARNING
■After recharging the battery
Have the battery inspected at any
authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer as soon as possible.
If the battery is deteriorating, contin- ued use may cause the battery to emit a malodorous gas, which may be
detrimental to the health of passen- gers.
■When replacing the battery
●For information regarding battery replacement, contact any autho-
rized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●After replacing, securely attach the exhaust hose and exhaust hole
plug to the exhaust hole of the replaced battery. If not properly installed, gases (hydrogen) may
leak into the vehicle interior, and there is the possible danger of the gas igniting and exploding.
NOTICE
■When handling jumper cables
When connecting the jumper cables,
ensure that they do not become entangled in the cooling fan or engine drive belt.
■To prevent damaging the vehicle
The exclusive jump starting terminal
is to be used when charging the bat- tery from another vehicle in an emer-gency. It cannot be used to jump start
another vehicle.
