Warning
We recommend that you have battery
changes carried out by a Vauxhall
Authorised Repairer. They know the laws
concerning the disposal of used batteries
and therefore protects the environment
and your health.
Retrofitted electrical or electronic
accessories can place an additional load
on the battery or even discharge the
battery. We recommend that you consult a
Vauxhall Authorised Repairer regarding
technical possibilities, such as fitting a
more powerful battery.
Laying up the vehicle for more than 4
weeks can lead to battery discharge, which
may reduce the service life of the battery.
Disconnect battery from on-board power
supply by detaching negative terminal
(Vauxhall alarm system 3 is then
disabled).
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 44, 47, 52.
z Activate window and sun roof
electronics 3 if necessary – see
pages 138, 141.
In order to prevent the battery from
discharging, some consumers such as the
courtesy light automatically switch off
after approx. 20 minutes.

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).

Warning
Electronic ignition systems generate very
high voltages. Do not touch the ignition
system; high voltage can be fatal.
Disconnecting/connecting vehicle battery
from/to 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.
