■Starting the engine when t he battery 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 i s stopped.
(Vehicles with Stop & Start system: except when the engine is s topped by
the Stop & Start system.)
● Turn off any unnecessary electrical components when the vehicle is running
at a low speed for an extended period, such as in heavy traffic .
■ When recharging or replacing the battery
●Vehicles with a smart key system: In some cases, it may not be possible to
unlock the doors using the smart key system when the battery is dis-
charged. Use the wireless remote control or the mechanical key to lock or
unlock the doors.
● Vehicles with a smart key system: The engine may not start on t he first
attempt after the battery has recharged but will start normally after the sec-
ond attempt. This is not a malfunction.
● Vehicles with a smart key system: The engine switch mode is memorized by
the vehicle. When the battery is reconnected, the system will r eturn to the
mode it was in before the battery was discharged. Before disconnecting the
battery, turn the engine switch off.
If you are unsure what mode the engine switch was in before the battery dis-
charged, be especially careful when reconnecting the battery.
● Vehicle with power back door: The power back door must be initi alized.
( P. 694)
● Vehicles with Stop & Start system: After the battery terminals have been dis-
connected then reconnected or the battery has been replaced, th e Stop &
Start system may not automatically stop the engine for approximately 5 to
60 minutes.
■ Charging the battery
The electricity stored in the battery will discharge gradually even when the
vehicle is not in use, due to natural discharge and the draining effects of cer-
tain electrical appliances. If the vehicle is left for a long t ime, the battery may
discharge, and the engine may be unable to start. (The battery recharges
automatically during driving.)
■ When exchanging the battery (vehicles with Stop & Start system)
Use a genuine battery specifically designed for use with a Stop & Start sys-
tem or equivalent. 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 your Toyota
dealer for details.
