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). 
Disconnecting / connecting the battery 
from / to the electrical system 
Disconnect the battery from the vehicle 
electrical system before charging: First 
detach the negative and then the positive 
lead. Do not reverse the polarity of the 
battery, i.e. do not confuse the terminals 
for the positive and negative leads. When 
connecting, start with the positive lead and 
then connect the negative lead.
