BMW 7 Series: Jump-starting
General information
If the battery is discharged, the engine can be started using the battery of another vehicle and two jumper cables. Only use jumper cables with fully insulated clamp handles.
Safety information
DANGER
Contact with live components can lead to an electric shock. There is a risk of injuries or danger to life. Do not touch any components that are under voltage.
Warning
If the jumper cables are connected in the incorrect order, sparking may occur. There is a risk of injury. Pay attention to the correct order during connection.
NOTICE
In the case of body contact between the two vehicles, a short circuit can occur during jumpstarting.
There is a risk of damage to property.
Make sure that no body contact occurs.
Preparation
- Check whether the battery of the other vehicle has a voltage of 12 volts. The voltage information can be found on the battery.
- Switch off the engine of the assisting vehicle.
- Switch off any electronic systems/power consumers in both vehicles.

Connecting the cables
Before you begin, switch off all unnecessary electronic systems/power consumers, such as the radio, on the assisting and receiving vehicle.
- Open the cover of the starting aid terminal.
- Attach one terminal clamp of the positive jumper cable to the positive terminal of the battery, or to the corresponding starting aid terminal of the vehicle providing assistance.
- Attach the terminal clamp on the other end of the cable to the positive terminal of the battery, or to the corresponding starting aid terminal of the vehicle to be started.
- Attach one terminal clamp of the negative jumper cable to the negative terminal of the battery, or to the corresponding engine or body ground of assisting vehicle.
- Attach the second terminal clamp to the negative terminal of the battery, or to the corresponding engine or body ground of the vehicle to be started.
Starting the engine
Never use spray fluids to start the engine.
- Start the engine of the assisting vehicle and let it run for several minutes at an increased idle speed.
- Start the engine of the vehicle that is to be started in the usual way.
If the first starting attempt is not successful, wait a few minutes before making another attempt in order to allow the discharged battery to recharge.
- Let both engines run for several minutes.
- Disconnect the jumper cables in the reverse order.
Check the battery and recharge, if needed.
