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.

5168-2. Steps to take in an emergency
moving parts as shown in the illustration
5 Start the engine of the second
vehicle. Increase the engine
speed slightly and maintain at
that level for approximately 5
minutes to recharge the battery
of your vehicle.
6 Vehicles with a smart entry &
start system: Open and close
any of the doors of your vehicle
with the engine switch OFF.
7 Maintain the engine speed of
the second vehicle and start the
engine of your vehicle by turning
the engine switch to ON.
8 Once the vehicle’s engine has
started, remove the jumper
cables in the exact reverse
order from which they were con-
nected.
9 1ZR-FAE engine: Reinstall the
engine cover.
9 M15A-FKS engine: Reinstall the
positive (+) battery terminal
cover.
Once the engine starts, have the
vehicle inspected at any author-
ized Toyota reta iler or Toyota
authorized repairer, or any reliable
repairer as soon as possible.
■Starting the engine when the bat- tery is discharged
The engine cannot be started by
push-starting.
■To prevent battery discharge
●Turn off the headlights and the audio
system while the engine 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.
■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.547)
■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 author-
ized Toyota retailer or Toyota authorized 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 una-
ble to start. (The battery recharges auto- matically during driving.)
■When recharging or replacing the
battery (vehicles with a smart entry
& start system)
●Vehicles with entry function: In some
cases, it may not be possible to unlock the doors using the smart entry
& start system when the battery is dis-
charged. 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.
