276 Service plan, maintenance
Battery
The battery is maintenance-free.
Retrofitting of electrical or electronic
accessories can discharge or add extra
load to the battery. Take advice on the
technical possibilities, e.g. use of 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 110, 113, 118.
z Activate window and sun roof
electronics 3 if necessary – see
pages 44, 47.
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
Disconnect battery from vehicle power
supply before charging: disconnect
negative cable first, then the positive
cable.
The polarity of the battery, i.e. the positive
and negative terminal connections, must
not be switched. Always connect the
positive cable first, then the negative
cable.
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).
