Starting using another
battery
When your vehicle's battery is discharged, the engine can be started using a slave battery (external or on another vehicle) and jump lead cables.
Remove the plastic cover from the (+) terminal, if your vehicle has one. Connect the red cable to the positive terminal (+) of the flat battery A , then to the positive terminal (+) of the slave battery B . Connect one end of the green or black cable to the negative terminal (-) of the slave battery B (or earth point on the other vehicle). Connect the other end of the green or black cable to the earth point C on the broken down vehicle (or on the engine mounting).
Start the engine of the vehicle with the good battery 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 straight away, switch off the ignition and wait a few moments before trying again. Wait until the engine returns to idle then disconnect the jump lead cables in the reverse order. Refit the plastic cover to the (+) terminal, if your vehicle has one.
First check that the slave battery has a nominal voltage of 12 V and a capacity at least equal to that of the discharged battery. Do not try to start the engine by connecting a battery charger. Do not disconnect the (+) terminal when the engine is running.
