Ignition Off When Disconnecting Battery Notice

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.

NOTE: Push starting the vehicle can, under some conditions, cause damage to the catalytic converter and an automatic transmission.

IMPORTANT: Do not let the cable end touch any metal while the other cable end is still connected.

IMPORTANT: Do not use the boost, the jump start or the 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.

IMPORTANT: Do not charge a battery with a green hydrometer dot unless it has just been discharged, such as in cranking.
