the last few inches. You should hear the
lock mechanism engage. Then attempt
to move the hood above the left and
right headlamps to ensure that the lock
has engaged securely.
To avoid injuries, be sure that the
travel path of the hood is clear
when it is closed, as with all closing
procedures. If it is determined that the
hood is not completely closed while
driving, stop immediately and close
it securely.<

BatterySymbolsYou 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.
A highly-explosive gas is gener-
ated when the battery is
charged.
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.
In order to protect the battery
case from ultraviolet radiation,
do not expose it to direct
sunlight. A discharged battery can
freeze. Store the battery in areas where
temperature remains above freezing.
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.
Wear eye protection. Do not
allow particles containing
battery acid or lead to come into
contact with your eyes, your skin, or
your clothing.
If you happen to get acid in your
eyes, rinse thoroughly for
15 minutes with clear water.
Following that, consult a physician
immediately. If your skin or clothing are
splashed by acid, rinse immediately
with plenty of soap and water. If elec-
trolyte is accidentally ingested, consult
a physician immediately.
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.<

BatteryCharging 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
disconnect 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. Then recharge the battery 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 recy-
cling point or your BMW center.
Maintain the battery in an upright posi-
tion 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.
Comply with the information on this
subject on page 130.<
