Protecting electronic components
In order to prevent faults in electronic
components in the electrical system, never
connect or disconnect battery with engine
runningor ignition switchedon. Never start
engine with battery disconnected, e.g.
when starting using jump leads.
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.
Parking the vehicle for more than 4 weeks
can lead to battery discharging. This may
reduce the service life of the battery.
Disconnect battery from on-board power
supply by disconnecting the negative
terminal.
To avoid damaging the vehicle, do not
make any modifications to the electrical
sy stem, e.g. connecting additional
consumers or tamp ering with electronic
control units (chip tuning).
The Vauxhall alarm system 3 siren mustbe
deactivated as follows: switch the ignition
on then off, disconnect the vehicle’s
battery within 15 seconds.

high voltages. Do not touch the ignition
system; high voltage can be fatal.
Ensure ignition is switched off before
connecting battery. Then perform the
following actions:
z Set date and time in information
display – see page 94,
z If necessary, activate the window
elec tronics 3 – see page 40,
