Your 3008 uses a lead-acid starter battery. These batteries contain harmful substances, sulphuric acid and lead, so you must handle them with care.
Disposal:
Safety when handling the battery:
Symbols on the battery:
On petrol and Diesel versions, the battery is under the bonnet. Here is how to reach it, start the engine using another battery, charge it and disconnect it.
Accessing the battery:
The (+) positive terminal has a quick-release terminal. The (-) negative terminal is not accessible, so a remote earth point is located near the battery.
Starting using another battery:
If your battery is flat, you can start the engine using a backup battery (external or from another vehicle) with jump leads, or using a battery booster. Before you begin:
If you drive off straight away before the battery has enough charge, some functions, such as Stop & Start, may be affected.
Charging the battery using a battery charger:
Keeping the battery properly charged is essential for its service life. You may need to charge it if you mainly make short journeys, or if the car will be off the road for several weeks. Consult a PEUGEOT dealer or a qualified workshop. If you charge it yourself:
Disconnecting and reconnecting the 12 V battery:
If the car will be unused for an extended period, disconnecting the battery is recommended so that it keeps enough charge to start the engine. You only need to disconnect the (+) terminal.
To disconnect the (+) terminal using the quick-release clamp:
To reconnect the (+) terminal:
Do not force the lever. If the clamp is not positioned correctly, it will not lock, so start the procedure again. Stop & Start may not work during the trip after the first engine start. It will only be available again after the car has been immobilised continuously for a period that depends on the outside temperature and the battery's state of charge (up to about 8 hours).
On hybrid versions, the hybrid system starts the car, but it still needs a 12 V supply. There are several reasons why the car might not start. If the 12 V battery is flat, you can provide the 12 V supply with a backup battery (external or from another vehicle) and jump leads, a battery booster or a battery charger.
Starting using another battery:
If you drive off straight away before the battery has enough charge, some functions, such as e-Auto mode, may be affected.
Charging the 12 V battery using a battery charger:
Keeping the battery properly charged is essential for its service life. You may need to charge it, for example if the car will be off the road for several weeks. Consult a PEUGEOT dealer or a qualified workshop. The hybrid system is connected to the 12 V network through the DC/DC converter, so any operation may affect how the whole system behaves. If you charge it yourself:
Charging the 48 V battery using a 12 V battery charger:
If the car does not start, first follow the procedure for starting using another battery. If that fails, especially after long storage, the 48 V battery may be discharged and need charging.
The rechargeable hybrid system has two accessory batteries, one at the front and one at the rear of the car. To replace them, contact a PEUGEOT dealer or a qualified workshop. Do not start or jump-start another vehicle using your car's accessory batteries.
Accessing the front battery:
The (+) positive terminal has a quick-release terminal. The (-) negative terminal is not accessible, so a remote earth point is located near the battery.
Accessing the rear battery:
The (+) positive terminal is protected by a red plastic cover and is not accessible. The (-) negative terminal has a black quick-release connector.
Charging the front battery using a battery charger:
Keeping the front battery properly charged is essential for its service life. You may need to charge it if you mainly make short journeys, or if the car will be off the road for several weeks. Consult a PEUGEOT dealer or a qualified workshop. If you charge it yourself:
Disconnecting and reconnecting the accessory batteries:
Use this procedure if the car will be immobilised for a long time. Never change the order of the steps, as this risks irreversible damage.
To disconnect, in this order:
To reconnect, in this order:
After reconnecting the battery, give the electronic systems time to initialise before you start the engine.
On right-hand drive versions, when the total distance recorder has reached 62 miles (100 km), you must wait approximately 15 minutes before starting the engine. If minor problems still persist afterwards, contact a PEUGEOT dealer or a qualified workshop.
Using the relevant section of the handbook, reinitialise this equipment:
When you switch on the ignition after reconnecting the battery, the message “Collision risk detection system fault” appears on the instrument panel. This is perfectly normal, and the message disappears while you drive.
On petrol, Diesel and hybrid versions, the battery is under the bonnet. Rechargeable hybrid versions have two accessory batteries, one under the bonnet and one under the boot floor.
Let the engine run for at least 30 minutes with the car stationary so the battery reaches an adequate state of charge. If you drive off straight away, functions such as Stop & Start or e-Auto mode may be affected.
No. The handbook says you must not start or jump-start another vehicle using the rechargeable hybrid's accessory batteries.
The message “Collision risk detection system fault” is normal when you switch on the ignition after reconnecting the battery. It disappears while you drive.
A flat or disconnected battery is easy to deal with once you know the right order of steps for your 3008. Take your time, follow the safety rules, and if anything seems wrong, contact a PEUGEOT dealer or a qualified workshop.
