Protecting Electronic Components - Vauxhall Corsa Owner's Manual

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 (Vauxhall alarm system 3 is then
disabled).
Ensure that ignition is switched off before
connecting battery. Then perform the
following actions:
z Remove Radio block 3, see radio
operating instructions.
z Set date and time in information
display – see page 40.
z Activate window electronics 3 – see
page 96.
z Calibrate steering angle sensor (ESP) 3 –
see page 139.
In order to prevent the battery from
discharging, some consumers such as the
courtesy light automatically switch off
after approx. 30 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.
Disconnect the battery from the vehicle
electrical system before charging: First
detach the negative and then the positive
cable. The polarity of the battery, i.e. the
connectors for the positive and negative
cables, must never be confused. When
reconnecting, first attach the positive and
then the negative cable.
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).
Electronic ignition systems generate very
high voltages. Do not touch the ignition
system; high voltage can be fatal.
