Vehicle Damage Warnings

NOTE: Turn OFF the ignition when connecting or disconnecting the battery cables, the battery charger or the jumper cables. Failure to do so may damage the PCM or other electronic components.

IMPORTANT: Do not use the boost, jump start or crank setting for prolonged charging of batteries if the charger is equipped with these settings. Using any of these settings for a prolonged period may cause gassing or spewing of electrolyte through the vent hole.
