Toyota Yaris: If Trouble Arises / Battery Runs Out

Jump-Starting

Jump-starting is dangerous if done incorrectly. So follow the procedure carefully. If you feel unsure about jump-starting, we strongly recommend that you have a competent service technician do the work.

1. Move the booster vehicle so that its battery is as close as possible to your vehicle’s battery.
2. Make sure that the power such as for the headlights and air conditioner is turned off.
3. Remove the battery cover.

   

4. Turn off the booster vehicle’s engine and connect the jumper cables in the following order.

   Make sure that the jumper cables are securely connected so that they do not disconnect due to engine vibrations.

   1st lead:

   1. Positive (+) terminal on the discharged battery
   2. Positive (+) terminal on booster vehicle’s battery

   2nd lead:

   1. Negative (-) terminal on booster vehicle’s battery
   2. Location shown in the figure (do not connect to the negative (-) terminal of the battery)

   

5. Start the booster vehicle’s engine and rev the engine.
6. Start the engine of your vehicle. Run the engines for about 3 minutes to temporarily charge the battery of your vehicle.
7. Disconnect the jumper cables in the reverse order of their connection.
8. Install the battery cover.
9. Have your vehicle inspected by your Toyota dealer as soon as possible.

WARNING

Follow These Precautions Carefully

To ensure safe and correct handling of the battery, read the following pre- cautions carefully before using the battery or inspecting it.

Keep flames and sparks away from open battery cells and do not allow metal tools to contact the positive (+) or negative (-) terminal of the battery when working near a battery. Do not allow the positive (+) terminal to contact the vehicle body

Flames and sparks near open battery cells are dangerous. Hydrogen gas, produced during normal battery operation, could ignite and cause the battery to explode. An exploding battery can cause serious burns and injuries. Keep all flames including cigarettes and sparks away from open battery cells.

Keep all flames and sparks away from open battery cells because hydrogen gas is produced from open battery cells while charging the battery or adding battery fluid

Flames and sparks near open battery cells are dangerous. Hydrogen gas, produced during normal battery operation, could ignite and cause the battery to explode. An exploding battery can cause serious burns and injuries. Keep all flames including cigarettes and sparks away from open battery cells.

Do not jump-start a frozen battery or one with a low fluid level

Jump-starting a frozen battery or one with a low fluid level is dangerous. It may rupture or explode, causing serious injury.

Connect the negative cable to a good ground point away from the battery

Connecting the end of the second jumper cable to the negative (-) terminal of the discharged battery is dangerous.

A spark could cause the gas around the battery to explode and injure someone.

Route the jumper cables away from parts that will be moving

Connecting a jumper cable near or to moving parts (cooling fans, belts) is dangerous. The cable could get caught when the engine starts and cause serious injury.

NOTICE

Use only a 12 V booster system. You can damage a 12 V starter, ignition system, and other electrical parts beyond repair with a 24 V power supply (two 12 V batteries in series or a 24 V motor generator set).
