Battery, Removing and Installing

Battery, Removing And Installing


CAUTION!
Disconnect the battery Ground (GND) strap before working on the electrical system.


NOTE:
- Before disconnecting the battery, determine the correct coding for the anti-theft radio.
- Once the battery is reconnected, check and activate the vehicle's electrical equipment (radio, clock, comfort and convenience features, etc.).

Installing


NOTE:
- The newest generation of batteries is equipped with a central gas vent and flame trap by means of a "baffle. "
- Function: the gas produced during charging escapes at one place through an opening in the top of the cover. The flame trap (which prevents the flammable gas located in the battery from igniting) is also integrated in this unit.
- For proper venting of the battery via the diffuser and the hose, it is important that the hose attached to the central gas vent does not become pinched off during installation.
- The diffuser consists of a small round glass fiber mat having a diameter of approximately 75 mm and a thickness of 2 mm. It functions similar to a valve, i.e., it allows the gas formed in the battery to flow out.







When installing the battery (if the battery has a central gas vent), make absolutely certain that the hose is not pinched off. This allows the battery be freely vented via the diffuser and the hose. If the battery does not have a hose, make sure that the opening or of the battery's cover is not plugged.


- Install in reverse order of removal the top

Make sure battery is securely mounted
If the battery is not secured properly, there is a risk that the following might occur:
- Shortened service life due to damage caused by vibration
- Battery cell and plate damage
- Damage to battery case by the hold-down clamp (possible release of electrolyte resulting in costly damage).
- Poor collision safety
