nals are not corroded and that there
are no loose connections, cracks,
or loose clamps.
Te r m i n a l s
Hold-down clamp
■Before recharging
When recharging, the battery produces hydrogen gas which is flammable and
explosive. Therefore, observe the fol-
lowing precautions before recharging:
●If recharging with the battery installed
on the vehicle, be sure to disconnect the ground cable.
●Make sure the charger is off when connecting and disconnecting the
charger cables to the battery.
■After recharging/reconnecting the
battery (vehicles with a smart entry & start system)
●Vehicles with entry function: Unlock-ing the doors using the smart entry &
start system may not be possible
immediately after reconnecting the battery. If this happens, use the wire-
less remote control or the mechanical
key to lock/unlock the doors.
●Start the engine with the engine
switch in ACC. The engine may not
start with the engine switch turned off. However, the engine will operate nor-
mally from the second attempt.
●The engine switch mode is recorded
by the vehicle. If the battery is recon-
nected, the vehicle will return the engine switch mode to the status it
was in before the battery was discon-
nected. Make sure to turn off the engine before disconnecting the bat-
tery. Take extra care when connecting
the battery if the engine switch mode prior to discharge is unknown.
If the system will not start even after
multiple attempts, contact any author- ized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
