Overview

I-Start is a dual battery system designed to
secure cranking and provide a longer service
life for the batteries
In order to achieve this, vehicle loads are split
in two systems:
•
Chassis electronics (connected to Starter
Batteries)
•
Body electronics (connected to Consumer
Batteries)
All the electric devices are connected to the
consumer batteries (Coffee makers, Lamps,
Power outlets, etc).
WARNING
On vehicles with I-Start there is voltage
in the starter batteries even if the battery
main switch is disengaged. In order to
fully de-energize the vehicle, the cables on
the battery terminals must be disconnected
from both the starter batteries and the
consumer batteries.
