Whether you’re changing the 12 V battery or working near the airbags, disconnecting it safely on the Daihatsu Cuore (L276) takes a couple of precautions. The battery is in the engine compartment, and a short wait before and after protects the car’s electronics and pyrotechnic parts.
Disconnecting the battery
- First, make sure you have the radio security code to hand — disconnecting power can lock the audio system until the code is re-entered.
- Switch the ignition off and remove the key. Wait one minute before touching the battery so the control units power down fully.
- Open the hood and find the battery in the engine compartment (right-hand side). Slacken the clamp nut on the negative (−) terminal first and lift the lead clear.
- If you’re removing the battery, undo the positive (+) terminal and the hold-down clamp, then lift the battery out keeping it upright.
- If you’ll be working on airbags or seat-belt pretensioners, wait a further minute after disconnecting before starting that work.
Reconnecting the battery
- Refit the battery, then connect the positive (+) terminal first and the negative (−) terminal last. Tighten both clamps so they can’t move.
- Switch the ignition on and reset the clock (date and time).
- Re-enter the radio code if prompted, then re-store your radio presets and any personal settings.
- Start the engine and check that no warning lights stay on. A short drive lets everything re-sync.
There’s no electronic throttle or window re-learn needed on this generation of Cuore — once the clock and radio are set, the car is ready to use.
Frequently Asked Questions
Which terminal do I disconnect first?
Always the negative (−) terminal first when disconnecting, and the negative last when reconnecting. That order prevents accidental short circuits against the bodywork.
Will I lose my radio and clock settings?
Yes. Cutting the 12 V supply clears the clock and radio presets, and may ask for the audio security code. Have the code before you start and note your presets.
How long should I wait after switching off?
About one minute before disconnecting, and a further minute before working on airbags or pretensioners, so the systems power down safely.
Working on another make? Look up any fault code on autodtcs.com.
