Procedure for starting the engine using another battery or for charging a discharged battery.
Accessing the battery
The battery is located under the bonnet.
For access to the (+) terminal:
- Release the bonnet by pulling the internal release lever, and then the external safety catch.
- Raise the bonnet.
(+) Positive terminal with a quick-release terminal.
(-) Negative terminal.
As the battery’s negative terminal is not accessible, a remote earth point is located near the battery.
Starting using another battery
If the vehicle’s battery is flat, the engine can be started using a backup battery (either external or from another vehicle) and jump leads or using a battery booster.
Never start the engine by connecting a battery charger. Never use a 24 V or higher battery booster. Check beforehand that the backup battery has a nominal voltage of 12 V and a capacity at least equal to that of the discharged battery.
The two vehicles must not be in contact with each other. Switch off all electricity-consuming equipment on both vehicles (audio system, wipers, lighting, etc.). Make sure that the jump leads are well away from the engine’s moving parts (fan, belt, etc.). Do not disconnect the (+) terminal while the engine is running.
- Lift the plastic cover on the (+) terminal, if the vehicle has one.
- Connect the red cable to the (+) terminal of flat battery A (at the metal elbow), then to the (+) terminal of the backup battery B or of the booster.
- Connect one end of the green or black cable to the (-) terminal of the backup battery B or of the booster (or to an earth point on the assisting vehicle).
- Connect the other end of the green or black cable to the earth point C.
- Start the engine on the assisting vehicle and leave it running for a few minutes.
- Operate the starter on the broken-down vehicle and let the engine run.
If the engine does not start immediately, switch off the ignition and wait a few moments before trying again. - Wait for it to return to idle.
- Disconnect the jump leads in reverse order.
- Refit the plastic cover to the (+) terminal, if the vehicle has one.
- Allow the engine to run for at least
30 minutes, with the vehicle stationary, so that the battery reaches an adequate state of charge.
Driving immediately without having
reached a sufficient level of charge may affect some of the vehicle’s functions (e.g. Stop & Start).
Charging the battery using a battery charger
For optimum service life of the battery, it is essential to maintain an adequate state of charge.
In some circumstances, it may be necessary to charge the battery:
- When using the vehicle mainly for short journeys.
- If the vehicle is to be taken off the road for several weeks.
Consult a PEUGEOT dealer or a qualified workshop.
To charge the vehicle’s battery yourself, use only a charger compatible with lead-acid batteries with a nominal voltage of 12 V.
Follow the instructions provided by the manufacturer of the charger. Never reverse polarities.
It is not necessary to disconnect the battery.
- Switch the ignition off.
- Switch off all electrical consumers (audio system, lighting, wipers, etc.).
- Switch off charger B before connecting the cables to the battery, to avoid any dangerous sparks.
- Ensure that the charger cables are in good condition.
- Lift the plastic cover on the (+) terminal, if the vehicle has one.
- Connect the cables of charger B as follows:
- the positive (+) red cable to the (+) terminal of battery A.
- the negative (-) black cable to earth point C on the vehicle.
- At the end of the charging operation, switch off charger B before disconnecting the cables from battery A.
If this label is present, use only a 12 V charger to avoid causing irreversible damage to the electrical components.
Disconnecting/reconnecting the battery
To maintain an adequate state of charge for starting the engine, we recommend disconnecting the battery if the vehicle is to be unused for an extended period.
Before disconnecting the battery:
- Close all openings (doors, boot, windows, roof).
- Switch off all electricity-consuming devices (audio system, wipers, lamps, etc.).
