Jump Starting: Service and Repair
JUMP START SWITCHA jump start switch is located on the driver s side kick panel. Pushing the jump start switch starts an 8 minute timer and a dedicated 12 volt to high voltage battery charger located inside the HV battery case. This battery charger allows a customer to charge the high voltage battery from a 12 volt donor source.
The jump start feature is needed because the starter function is built into the eCVT which is powered by the high voltage system. Over extended periods of time at high temperatures, the HV battery can lose its charge just as a low voltage battery can.
The 12 volt donor is initially the Tribute s own 12 volt battery. If this fails, the jump start procedure can be repeated using an auxiliary 12 volt power supply connected to the 12 volt battery like a conventional jump start procedure.
