166 Vehicle care
An AGM battery can be identified by
the label on the battery. We
recommend the use of an original
Opel battery.
Note
Using an AGM battery different from
the original Opel battery might result
in a lower performance of the stop-
start system.
9 Warning
When fitting a battery with a length
deviating from the original one, it
is essential to ensure a proper
fitting of the buffer element.
We recommend that you have the
battery replaced by a workshop.
Stop-start system 3 131.

9 Warning
On vehicles with stop-start
system, ensure that the charging
potential does not exceed 14.6
