Battery care

The battery is absolutely maintenance-
free, that is, the original electrolyte will
normally last for the service life of the
battery under moderate climatic condi-
tions.

For all questions that regard the
battery, please consult your BMW

center. Since the battery is mainte-
nance-free, the following is for your
information only.

Symbols

You will find the following symbols on
your vehicle battery. To avoid injury,
please comply with the corresponding
precautions whenever you work with or
near the battery.

Before handling the battery,
please read the following infor-
mation.

Wear eye protection. Do not
allow particles containing
battery acid or lead to come into

contact with your eyes, your skin, or
your clothing.

Battery acid is extremely corro-
sive. Wear eye protection and
protective gloves. Do not tip the

battery. Battery acid can leak from the
ventilation openings.

Do not allow children access to
batteries and battery acid.

Never allow sparks or open
flame in the vicinity of the
battery. Avoid sparks from elec-

trical cables or electrical equipment.
Turn the key to position 0 in the
steering lock when disconnecting or
connecting the battery. Do not short-
circuit the battery terminals. This
creates a risk of injury from high-energy
sparks.

A highly explosive gas is gener-
ated when the battery is charged.

If battery acid is splashed into
your eyes, immediately rinse
them with clear water for

15 minutes. Consult a physician imme-
diately. If your skin or clothing are
splashed by acid, rinse immediately
with ample clear water. If battery acid is
accidentally swallowed, consult a
physician immediately.

In order to protect the battery
case from ultraviolet radiation,
do not place it in direct sunlight.

A discharged battery can freeze. Store
the battery in areas where temperature
remains above freezing.

Removal and installation

Do not disconnect the battery
when the engine is running. If you

do so, the ensuing voltage surge will
damage the vehicle's onboard elec-
tronics.
Do not make any modifications in the
wires to the positive terminal. If you do
so, the protective function of the safety
battery terminal is no longer ensured.
Repair and disposal must be performed
by trained technicians only.

When removing the battery, disconnect
the cable on the negative terminal first,
then the cable on the positive terminal.
Loosen the center adjusting screw on
the battery retaining strap (use the
screwdriver included with the onboard
tool kit) and disconnect the strap.

When installing a battery, connect the
positive terminal first, then connect the
negative terminal.

When installing a battery, be sure
that it is mounted properly and

that the retaining bracket is installed
with the center adjustment screw. If this
is not done, the battery will not be
adequately secured in case of an acci-
dent.
