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.367)
■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.
