Lamps and bulbs
163 n
The lamps and bulbs make essential contributions to the safety of your vehicle. Observe the following instructions during bulb replacement carefully. If you are not familiar with any of the procedures, consult your authorized BMW center.
Do not touch the glass portion of a new bulb with your bare hands since even small amounts of impurities burn in to the surface, thus reducing the service life of the bulb. Use a clean cloth, paper napkin, or a similar material, or hold the bulb by its metallic base.
<
Whenever working on the electrical system, switch off the electrical accessory you are working on or disconnect the cable from the negative terminal of the battery. Failure to do this could result in short circuits.
To prevent injuries and damage, comply with any instructions provided by the bulb manufacturer.

Jump-starting
179 n
Never use spray starter fluids to start the engine.
If the battery is discharged, you can use two jumper cables to start your car with power from the battery of a second vehicle. Always use jumper cables with fully insulated handles on the terminal clamps.
Do not touch high-voltage wiring and cables on a running engine.
There is a risk of fatal injury if you do this.
<
Carefully comply with the following instructions to avoid personal injury and damage to one or both vehicles:
1 Ensure that the battery on the support vehicle is also rated at 12 volts, and that the capacities of the two batteries (Ah) are roughly comparable
(printed on casing)
2 Leave your battery connected to the car electrical system
3 Make sure that there is no contact between the bodywork of the two vehicles – short circuit risk.
