Risk of injury. Follow all warnings and safety precautions, refer to BATTERY GENERAL INFORMATION .
Battery recharging or Battery jump start terminal on vehicles with the start/stop system.
Connect the positive pole first and then the body ground using a charge cable. This ensures that the Battery Monitoring Control Module -J367- is not bridged. Charging the Battery directly on the negative terminal bridges the Battery Monitoring Control Module -J367- and prevents the Battery Monitoring Control Module -J367- from recording the Battery data during the charging process. The values stored in the Data Bus On Board Diagnostic Interface -J533- regarding the Battery condition no longer match the values for the charged Battery -A-.
Removal
-- Disconnect the Battery -A-, refer to BATTERY, DISCONNECTING AND CONNECTING .
-- Remove the air filter housing and Mass Airflow Sensor -G70- and connecting tube, refer to Mass Air Flow Sensor -G70- .
-- Remove the bolt -2- and then remove the clamping plate.
-- Remove the Battery -A- -1-.
Installation
If the Battery -A- is not secured properly, the following risks are possible:
- Shortened Battery service life due damage caused by vibration (explosion hazard).
- If the Battery -A- is not secured properly, the plates inside the Battery -A- can get damaged.
- Damage to the Battery housing caused by bracket (possible electrolyte leakage, high subsequent costs).
- Inadequate crash safety.
Install in reverse order of removal. Note the following:
-- Make sure the Battery -A- is secure after Installation it.
-- Connect the Battery -A-, refer to BATTERY, DISCONNECTING AND CONNECTING .
