Protecting electronic components

In order to prevent faults in electronic
components in the electrical system, never
connect or disconnect battery with engine
running or ignition switched on. Never start
engine with battery disconnected, e.g.
when starting using jump leads.
To avoid damaging the vehicle, do not
make any modifications to the electrical
system, e.g. connecting additional
consumers or tampering with electronic
control units (chip tuning).
