The following procedures may be used to start the engine if the vehicle’s battery is discharged.
You can also call your toyota dealer or a qualified repair shop.
If you have a set of jumper (or booster) cables and a second vehicle with a 12-volt battery, you can jump start your vehicle by following the steps below.

Vehicles with a smart key system: maintain the engine speed of the second vehicle and start the engine of your vehicle by turning the engine switch to ignition on mode.
Once the engine starts, have the vehicle inspected at your toyota dealer as soon as possible.
Starting the engine when the battery is discharged
The engine cannot be started by push-starting.
To prevent battery discharge
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 certain electrical appliances. If the vehicle 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 key system)
If you are unsure what mode the engine switch was in before the battery discharged, be especially careful when reconnecting the battery.
