Battery switch Before storing the vehicle for an extended
period of several weeks or more, slide the
battery switch located behind the trim
panel on the right side of the luggage
compartment to OFF. This reduces the
current flow from the battery for the period
during which the vehicle remains parked.
A message appears in the Check Control
panel. Please take note of the supplemen-
tary information provided in the Control
Display.
Never disconnect either battery cable
from its terminal while the engine is
running Ð the resulting voltage surge would
destroy the vehicle's electronic systems.<
Return used batteries to a recycling
point or your BMW center. Maintain
the battery in an upright position for trans-
port and storage. Always restrain the
battery to prevent it from tipping over
during transport.< Fuses In the glove compartment Press the tab on the cover, see arrow, to
the front, then fold up the cover. Spare fuses and a set of tweezers are located
next to the fuse strip.
Never attempt to repair a blown fuse,
and do not replace a defective fuse
with a substitute of another color or
amperage rating, as this could lead to a
circuit overload, ultimately resulting in a fire
in the vehicle.<
In the luggage compartment Use the handle to pull down the trim on the
right wall.

Help Ð Giving and receiving Warning triangle*

The warning triangle is conveniently stored
in the onboard tool kit mounted on the
inside of the luggage compartment lid.
Comply with legal requirements
requiring you to carry a hazard
warning triangle in the vehicle.< First-aid kit*

You will also find the first-aid kit in the
onboard tool kit's container.
Some of the articles contained in the
first-aid kit have a limited service life.
For this reason, check the expiration dates
of each of the items regularly, and replace
any whose expiration dates have passed.
You can find replacements in any phar-
macy.
Always comply with laws requiring a first-
aid kit to be carried in the vehicle.< Jump-starting Never use spray fluids to start the engine.
When your battery is discharged you can
use two jumper cables to start your vehicle
with power from the battery in a second
vehicle. You can also use the same method
to help start another vehicle. Use only
jumper cables with fully-insulated clamp
handles. To avoid the risk of potentially fatal
injury, always avoid all contact with
electrical components while the engine is
running. Carefully adhere to the following
sequence, both to prevent damage to one
or both vehicles, and to guard against
possible personal injury.<
1.The battery in the support vehicle must
also be rated at 12 volts. This information
can be found on the sticker affixed to the
battery
2.Switch off the support vehicle's engine
and switch off all electrical equipment and
accessories in both vehicles (except the
hazard warning flashers on the support
vehicle)
3.Ensure that no contact exists between
the bodywork on the two vehicles as there
is a danger of short circuits
4.Your BMW is equipped with an auxiliary
terminal specifically designed for jump-
starting located within the engine compart-
ment. The symbol "+" is embossed on the
cover of this auxiliary terminal. Pull the
cover for access to the terminal, see
arrow 1 in the illustration.
Start by connecting one end of a jumper
cable to the positive terminal connected to
the discharged battery, then connect the
other end to the positive terminal of the
battery on the support vehicle
5.Connect the ends of the other jumper
cable to the negative terminals on both
vehicles. Connect the other end to the
negative battery terminal or a suitable
