Warning
Have the battery change performed by a
workshop. Please comply with the legal,
environmental and health regulations as
regards the disposal of old batteries.
Fitting of electrical or electronic accessories
at a later date can discharge or add extra
load to the battery. Take advice on the
technical possibilities, e.g. use of a more
powerful battery.
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.
The Vauxhall alarm system 3 siren must be
deactivated as follows: switch the ignition
on then off, disconnect the vehicle's
battery within 15 seconds.
Ensure that ignition is switched off before
connecting battery. Then perform the
following actions:
z Setting date and time in the information
display, see pages 124, 127, 132.
z If necessary activate the window and
sunroof electronics 3, see pages 51, 54.
In order to prevent the battery from
discharging, some consumers such as the
courtesy light automatically switch off
after approx. 20 minutes.
Disconnecting/connecting the battery
from/to the electrical system
Before charging, isolate the battery from
the on-board network. First remove the
negative and then the positive terminal.
Do not reverse the polarity of the battery,
i.e. the terminals for the positive and
negative leads. When connecting, start
with the positive lead and then connect the
negative lead.

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).
