When recharging or replacing the 12-volt battery in your Toyota RAV4 Hybrid

In some cases, it may not be possible to unlock the doors using the smart key system on your Toyota RAV4 Hybrid when the 12-volt battery is discharged. Use the wireless remote control or the mechanical key to lock or unlock the doors.

The hybrid system may not start on the first attempt after the 12-volt battery has recharged but will start normally after the second attempt. This is not a malfunction.

The power switch mode is memorized by the vehicle. When the 12-volt battery is reconnected, the system will return to the mode it was in before the 12-volt battery was discharged. Before disconnecting the 12-volt battery, turn the power switch off. If you are unsure what mode the power switch was in before the 12-volt battery discharged, be especially careful when reconnecting the 12-volt battery.

When removing the 12-volt battery terminals on your Toyota RAV4 Hybrid

  • Always remove the negative (-) terminal first. If the positive (+) terminal contacts any metal in the surrounding area when the positive (+) terminal is removed, a spark may occur, leading to a fire in addition to electrical shocks and death or serious injury.

  • Do not allow the other end of the jumper cable connected to the “+” terminal to come into contact with any other parts or metal surfaces in the area, such as brackets or unpainted metal.
  • Do not allow the + and - clamps of the jumper cables to come into contact with each other.
  • Do not smoke, use matches, cigarette lighters or allow open flame near the 12-volt battery.
