The procedure to initiate a non-operational Toyota Prius using an external power source involves specific steps to ensure safety and prevent damage to the vehicle’s hybrid system. This process bypasses the depleted 12-volt auxiliary battery, providing sufficient electrical current to start the vehicle’s computer and enable normal operation. Successfully implementing this procedure requires connecting jumper cables to the designated terminals under the hood, observing polarity, and cautiously transferring power from a functioning vehicle or portable jump starter.
Effectively restoring power to a disabled Prius allows continued use of a vehicle dependent on its hybrid system. This process avoids the expense and inconvenience of towing and potential delays in travel. Early models of Prius vehicles have sometimes experienced auxiliary battery failures, highlighting the need for drivers to understand this emergency measure. Furthermore, knowing this technique contributes to a driver’s overall preparedness and confidence in handling unexpected automotive issues.
