Disconnect and Reconnect the Battery

Last updated: June 12, 2026

Disconnecting the 12 V battery on your Lada Largus (R90, 2012–2024) — for a new battery, winter storage, or work near the airbags — is a straightforward job. The battery is in the engine compartment.

Find the Battery First

The 12 V battery is in the engine compartment, in the usual front corner. Note your radio security code and preset stations before you start.

Disconnecting Safely

1. Switch everything off and remove the key.
2. Disconnect the negative (−) terminal first, then the positive.
3. Working near airbags or seat-belt pretensioners? Wait a few minutes after disconnecting.

Reconnecting

Reconnect positive first, then negative. Afterwards:

• Re-enter the clock and radio code/presets.
• If a window loses one-touch, hold the switch fully up at the limit to relearn it.
• Warning lights settle after a short drive.

If Something Isn’t Right Afterwards

• Warning lights often clear after a short drive.
• A persistent light stores a code — look it up on autodtcs.com.
• Fit a like-for-like battery of the correct size and rating.
