Citroen C3: 12 V battery / Disconnecting the battery
In order to maintain an adequate state of charge
for starting the engine, it is recommended that
the battery be disconnected if the vehicle is
taken out of service for a long period.
Before disconnecting the battery:
- close all openings (doors, boot, windows),
- switch off all electrical consumers (audio
system, wipers, lighting, etc.),
- switch off the ignition and wait for four
minutes.
At the battery, it is only necessary to disconnect
the (+) terminal.
Quick-release terminal clamp
Disconnecting the (+) terminal

- Raise the lever A fully to release the clamp
B.
- Remove the clamp B by lifting it off.
Reconnecting the (+) terminal

- Raise the lever A fully.
- Refit the open clamp B on the (+) terminal.
- Push the clamp B fully down.
- Lower the lever A to lock the clamp B.
Do not force the lever as locking will not
be possible if the clamp is not positioned
correctly; start the procedure again.
Following reconnection
After reconnecting the battery, turn on the
ignition and wait 1 minute before starting the
engine, to enable the electronic systems to
initialise.
If minor problems nevertheless persist following
this operation, contact a CITROËN dealer or a
qualified workshop.
Referring to the relevant section, reinitialise
certain equipment:
- Remote control key or electronic key
