If the battery is discharged

The following procedures may be used to start the engine if the battery is discharged.

You can also call your Toyota dealer or 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 Toyota following the steps below.

Connecting the jumper cables.

Connecting the jumper cables.

  1. Positive (+) battery terminal on your vehicle.
  2. Positive (+) battery terminal on the second vehicle.
  3. Negative (-) battery terminal on the second vehicle.
  4. Connect the jumper cable to ground on your vehicles as shown in the illustration.


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.


Open and close any of the doors with the “ENGINE START STOP” switch off.


Maintain the engine speed of the second vehicle and start your vehicle’s engine.


Once the vehicle’s engine has started, remove the jumper cables in the exact reverse order in which they were connected.

Once the engine starts, have the vehicle checked at your Toyota dealer as soon as possible.

  • Starting the engine when the battery is discharged

The engine cannot be started by push-starting.

  • Avoiding a discharged battery

  • Turn off the headlights and the audio system while the engine is off.
  • Turn off any unnecessary electrical components when the vehicle is running at a low speed for an extended period, such as in heavy traffic, etc.
  • 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 the battery is removed or discharged

Make sure the key is not inside the vehicle when recharging or replacing the battery. The key may be locked in the vehicle if the alarm is activated.


  • Avoiding battery fires or explosions

Observe the following precautions to prevent accidentally igniting the flammable gas that may be emitted from the battery.

  • Make sure the jumper cable is connected to the correct terminal and that it is not unintentionally in contact with any part other than the intended terminal.
  • Do not allow the jumper cables to come into contact with the “+” and “-” terminals.
  • Do not allow open flame or use matches, cigarette lighters or smoke near the battery.
  • Battery precautions

The battery contains poisonous and corrosive acidic electrolyte, while related parts contain lead and lead compounds. Observe the following precautions when handling the battery:

  • When working with the battery, always wear safety glasses and take care not to allow any battery fluids (acid) to come into contact with skin, clothing or the vehicle body.
  • Do not lean over the battery.
  • If the battery fluid comes into contact with the skin or eyes, immediately wash the affected area with water and seek medical attention.

    Place a wet sponge or cloth over the affected area until medical attention can be received.

  • Always wash your hands after handling the battery support, terminals, and other battery-related parts.
  • Do not allow children near the battery.



  • When handling jumper cables

Be careful that the jumper cables do not become tangled in the cooling fan or any of the belts when connecting or disconnecting them.
