Battery
A highly explosive gas is
generated 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 ingested, consult a physi-
cian 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.
Removing and installing
Do not disconnect the battery
cable when 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
performed by specially trained
personnel.<
When removing, first disconnect the
cable to the negative terminal, then
disconnect the cable to the positive
terminal. Loosen the center adjusting
screw for the battery's retaining strap
(use the screwdriver found in the
onboard tool kit) and remove the
bracket.
When installing, first connect the cable
for the positive terminal, then the cable
for the negative terminal.
When installing, make sure that
the battery is seated properly, and
that the battery bracket is installed with
the center adjusting screw. Failure to
observe these precautions could result
in an inadequately secured battery,
which could then shift in an accident.<
Charging the battery Charge the battery in the vehicle only
when the engine is not running. Use the
connections provided in the engine
compartment (for correct connections,
refer to "Jump-starting" on page 145).
Before performing any work on
the electrical system, disconnect
the cable from the negative terminal. If
you do not, short circuits can create the
risk of fire or personal injury.<
If you plan to park the vehicle for longer
than 4 weeks, disconnect the battery
from the vehicle's electrical system by
disconnecting the cable at the negative
terminal. Then recharge the battery with
an appropriate battery charger.
If you intend to store the vehicle for
longer than 12 weeks, remove the
battery, charge it and store it in a cool
and dust-free room where there is no
danger of freezing. During storage,
have the battery recharged every six
months. Also, recharge the battery
before it is reinstalled. Failure to
observe these precautions can render
the battery unsuitable for continued
use. Every time the battery is
discharged, especially over extended
periods, its service life is reduced.

Battery Fuses
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.<
If an electrical accessory should fail,
switch it off and check the fuse.
The fuses, their individual ampere
ratings and the equipment in the
circuits they protect are all indicated on
the cover of the fuse box in the glove
compartment and on the inside of the
cover panel for the storage compart-
ment located behind the passenger's
seat.
In the glove compartment>Open the glove compartment
>Unlock the fuse box and swing it
downward
>Remove the lid with the list on it.
Spare fuses and plastic tweezers are
located in the fuse box lid behind the
passenger-side seat
>Use the plastic tweezers to remove
the fuse for the accessory or equip-
ment that has stopped working
>Replace a blown fuse, recognizable
by its melted metal strip, with a new
fuse that has the same color or
ampere rating.520de149

Do not use spray starter fluids to start
the engine.
If the battery is discharged, the engine
can be started with the use of two
jumper cables and the battery of
another vehicle. You can also use the
same method to help start another
vehicle. Use only jumper cables with
fully insulated grips on the terminal
clamps.
Do not touch high-voltage wiring
and cables on a running engine.
There is a risk of fatal injury if you do
this. Carefully comply with the following
instructions to avoid personal injury or
damage to one or both vehicles.<
1. Ensure that the battery in the support
vehicle is also rated at 12 volts. This
information is provided on the top of
the battery casing
2 Do not disconnect your battery from
your vehicle's electrical system.
Switch off all electrical accessories in
both vehicles
3 Make absolutely certain that there is
no contact between the bodywork of
the two vehicles Ð short circuit hazard
4 Start the engine on the support
vehicle and allow it to run
5. Use one jumper cable (+) to connect
the positive terminal of the battery in
the support vehicle with the auxiliary
positive terminal provided in the
engine compartment of your BMW
specifically for jump-starting. The
cover of the auxiliary terminal for use
in jump-starting your BMW is identi-
fied by a "+" symbol, refer to illustra-
tion. Lift off by pulling the tab (arrow) 520de088
6. Next, connect one end of the other
jumper cable (Ð) to either the support
vehicle's negative battery terminal or
a suitable ground on its engine or
bodywork. Connect the other end to
the negative battery terminal or a
suitable ground on the vehicle being
started. There is a special nut
provided for this on the BMW (see
illustration)
Follow the same sequence for
connecting the jumper cables,
otherwise, you run the risk of injury
caused by spark generation at the
battery.<520de133
Jump-starting

146n
Jump-starting Towing the vehicle7. Start the support vehicle's engine
and let it run at an increased idling
speed for a few minites. 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 let the engines run for a few
minutes
9. Then disconnect the jumper cables
in reverse sequence.
Depending on the cause of the fault,
have the battery recharged by your
BMW center.
Tow fittingThe screw-in tow fitting is stored in the
onboard tool kit; be sure that it remains
in the vehicle at all times. This fitting is
designed for installation in the tow
sockets located at the front and rear of
the vehicle. It is intended for towing on
paved road surfaces only.
It should not be used to pull a vehicle
out of deep snow, mud, sand, etc.
Always observe all applicable towing
laws and regulations.Access to tow socketsFront:
The uppermost grille stub is clipped on
the grille Ð which is located below the
main grille on the lower right Ð and this
grille can be pulled off, if you pull
forward on it.520de152
Rear
Use a screwdriver to press sideways
on the opening to remove the cover
(arrow).
Screw the tow fitting in until it
bottoms firmly. If this is not done,
the threads could be damaged.
Do not tow the vehicle by any compo-
nents of the running gear, or lash them
down in any way. If you do so, the
components could be damaged,
leading to possible accidents.<
Use only a nylon towing strap to tow
the vehicle. The inherent resilience of
this material helps protect both vehicles
from sudden jerking movements.520de164
