Solid, stationary, unpainted metallic point away from the battery and any
moving parts as shown in the illustration
4 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.
5 Vehicles with a smart entry &
start system: Open and close
any of the doors of your vehicle
with the engine switch OFF.
6 Maintain the engine speed of
the second vehicle and start the
engine of your vehicle by turning
the engine switch to ON.
7 Once the vehicle’s engine has
started, remove the jumper
cables in the exact reverse
order from which they were con-
nected.
Once the engine 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 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 stopped.
●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.431)
■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 (vehicles with a smart entry & start system)
●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
