230 Vehicle care
The vehicle battery is maintenance-
free provided that the driving profile
allows sufficient charging of the
battery. Short-distance-driving and
frequent engine starts can discharge
the battery. Avoid the use of
unnecessary electrical consumers.
Batteries do not belong in household
waste. They must be disposed of at
an appropriate recycling collection
point.
Laying up the vehicle for more than
4 weeks can lead to vehicle battery
discharge. Disconnect the clamp from
the negative terminal of the vehicle
battery.
Ensure the ignition is switched off
before connecting or disconnecting
the vehicle battery.
Battery discharge protection 3 137.
Replacing the vehicle battery
Note
Any deviation from the instructions
given in this paragraph may lead to
a temporary deactivation of the stop-
start system.
The vehicle battery is covered.
Remove the cover to replace the
battery. Lift up the cover at the rear
and unlatch it at the front.
When the battery is being replaced,
please ensure that there are no open
ventilation holes in the vicinity of the
positive terminal. If a ventilation hole
is open in this area, it must be closed
off with a dummy cap, and the
ventilation in the vicinity of the
negative terminal must be opened.
Only use vehicle batteries that allow
the fuse box to be mounted above the
battery.
In vehicles with stop-start system, be
sure to have the AGM (Absorptive
Glass Mat) battery replaced with an
AGM battery again.
An AGM battery can be identified by
the label on the battery. We
recommend the use of an original
Opel battery.
