BatteryBattery careThe battery is completely maintenance-
free. That means that the original
electrolyte will normally last for the
service life of the battery under
moderate 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.<
SymbolsYou 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 ignition
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 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 electrolyte
is accidentally ingested, 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.

BatteryRemoval 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
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.
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 accident.<
Charging the battery Charge the battery in the vehicle only
when the engine is not running.
Before doing any work on the
electrical system, be sure to
unclamp the cable from the battery's
negative terminal. Failure to do so can
result in short circuits, a fire or personal
injury.<
If you plan to park the vehicle for longer
than 4 weeks, disconnect the battery
from the vehicle electrical system by
disconnecting the cable at the negative
terminal. Have the battery recharged
with an appropriate battery charger.
If the vehicle is parked for more than
12 weeks, remove the battery, recharge
it and store it in a cool yet frost- and
dust-free area. During storage, have the
battery recharged every 3 months.
Also, recharge the battery before it is
reinstalled. If this is not done, the
battery will not be serviceable. Every
time the battery is discharged, espe-
cially over extended periods, its service
life is reduced.
Return used batteries to a
recycling center or your BMW
center. Maintain the battery in an
upright position for transport and
storage. Secure the battery to prevent it
from tilting during transport.<
Storage periods during which the
battery is disconnected are not
taken into consideration by the Service
Interval Display for changing the brake
fluid.
For this reason, be sure that the brake
fluid is changed every two years,
regardless of the information displayed.
Please read the pertinent information
on page 148.<

FusesIf an electrical accessory should fail,
switch it off and check the fuse. In the glove compartment1 Open the glove compartment and
turn the two white quick-release
fasteners outward. Spare fuses and
plastic tweezers are located on the
fuse holder.
2 Use the plastic tweezers to remove
the fuse for the accessory or equip-
ment that has stopped working.
3 If the fuse has blown (the metal strip
is melted and separated), replace it
with a new fuse of the same ampere
rating (color code).460de062
A list of fuses, their respective ampere
ratings and the equipment in their
circuits are all indicated below the fuse
holder.
To close the fuse holder, snap it into
position at the top and turn the two
fasteners inward.
Do not attempt to repair a burned
fuse or replace it with a fuse having
a different color or ampere rating. To do
this could cause a fire in the vehicle
resulting from a circuit overload.<
If a fuse blows repeatedly, refer the
problem to your BMW center for repair.

Do not use spray starter fluids.
If the battery is discharged, the engine
can be started with the use of two
jumper cables and the battery of
another vehicle. Use only jumper cables
with fully insulated grips on the terminal
clamps.
Do not touch the parts conducting
electrical current while the engine
is running. Failure to comply with this
creates a risk of fatal injury.<
Carefully comply with the following
instructions to avoid personal injury or
damage to one or both vehicles:
1 Be sure 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 the drained battery connected
to the vehicle's electrical system.
3 Make sure that there is no contact
between the bodywork of the two
vehicles Ð this creates a risk of short
circuits.
4 Start by connecting the jumper cable
from the positive terminal of the
support vehicle to the positive
terminal connector located in your
BMW's engine compartment. The
cover of the positive terminal
connector is marked with a "+" sign.
Refer to the illustration. Remove by
pulling the tab (arrow 1).
5 Then connect the negative terminals.
Attach the cable to either the support
vehicle's negative battery terminal, or
to a suitable ground on its engine or
bodywork. Then connect the other
end of the cable to a ground on the
engine or on the bodywork of the
vehicle that is to be started. There is
a special nut provided for this on the
BMW (arrow 2).
Follow the same sequence for
connecting the jumper cables
when helping other vehicles. If you do
not, there is the risk of injury if sparks
are generated at the battery.<462us053
6 Start the support vehicle's engine
and let it run.
7 Start the engine on the vehicle
needing the jump-start, and allow it
to run as usual. If the first start
attempt is not successful, wait a few
minutes before another attempt in
order to allow the discharged battery
to recharge.
8 Before disconnecting the jumper
cables from your BMW, turn on the
lighting, the rear window defroster
and set the blower to the highest
speed; allow the engine to run
approx. 10 seconds. This will prevent
a voltage surge from the voltage
regulator to the electrical accesso-
ries.
9 Then disconnect the jumper cables in
reverse sequence.
Depending on the cause of the fault,
recharge the battery.
