Battery care

The battery is completely maintenance-
free. That means that the original acid
will normally last for the service life of
the battery under temperate climatic
conditions.

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

center. Since the battery is absolutely
maintenance-free, the following is for
your information only.

Symbols

You will find the following symbols on
your vehicle battery. For your safety,
please be cautious whenever you work
with or near the battery.

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

Wear eye protection. Do not al-
low particles containing battery
acid or lead to come into con-

tact 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 to have
access to batteries and battery
acid.

Never allow sparks or open
flame near the battery. Do
not smoke in the vicinity of the

battery. Avoid sparks from electrical
cables or electrical equipment. Turn the
key to position 0 in the steering lock
when disconnecting or connecting the
battery. Never 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 you happen to get acid in
your eyes, rinse thoroughly for
15 minutes with clear water.

Consult a physician immediately. If you
get acid spray on your skin or clothing,
rinse with plenty of water. If 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
while the engine is running.

Disconnecting the battery cable when
the engine is running will cause a
voltage surge which will damage the
vehicle's onboard electronics.
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.
Repairs and disposal may only be per-
formed by specially trained personnel.

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 strap is installed using the
center adjustment screw, otherwise, the
battery will not be secure enough in
case of an accident.
