The following procedure must be performed before the vehicle’s 12V battery is replaced under warranty.
Connect a battery charger.
In some cases, the battery may be too low to allow the battery charger to start up. In such cases, the
charger can be started by “jump starting” it by connecting jumper cables from a good battery to the
damaged battery for a moment while the charger is connected. (The jumper cables only have to be
touched to the poles as the vehicle charger needs to see an initial voltage to start up. They can be taken
off as soon as the vehicle charger starts charging.)
