■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.
●Place the repair kit in a storage to
prevent it from being exposed to dirt or water.
●Store the repair kit in the luggage compartment out of reach of chil-dren.
●Do not disassemble or modify the repair kit. Do not subject parts such
as the air pressure indicator to impacts. This may cause a malfunc-tion.
■To avoid damage to the tire pres-sure warning valves and trans-
mitters
When a tire is repaired with liquid sealants, the tire pressure warning
valve and transmitter may not operate properly. If a liquid sealant is used, contact any authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer or other qualified ser-vice shop as soon as possible. After
use of liquid sealant, make sure to replace the tire pressure warning valve and transmitter when repairing
or replacing the tire. ( P.479)

Restarting the EV system

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.
