Lamps and bulbs The lamps and bulbs are essential
factors contributing to the safety of your
vehicle. Therefore, comply fully with the
following instructions during bulb
replacement. If you are not familiar with
any of the procedures, consult your
BMW center.
Do not touch the glass portion of
a new bulb with your bare hands
since even small amounts of impurities
burn into the surface and reduce the
service life of the bulb. Use a clean
cloth, paper napkin, or a similar mate-
rial, or hold the bulb by its metallic
base.<
A replacement bulb set is available from
your BMW center.
Whenever working on the
electrical system, switch off the
electrical accessory you are working on
or disconnect the cable from the nega-
tive terminal of the battery. Failure to do
this could result in short circuits.
To prevent injuries and damage,
comply with any instructions provided
by the bulb manufacturer.<

Changing a wheel Battery Driving with the space-saver tireDrive cautiously. Do not exceed a speed
of 50 mph (80 km/h).
You can anticipate changes in vehicle
handling such as delayed braking re-
sponse, longer braking distances and
changes in self-steering properties in
marginal stability limits.
The changes in handling characteristics
will be even more pronounced in
conjunction with winter tires.
Only one space-saver tire may be
mounted at one time. Reinstall
wheels and tires of the same size and
specification as soon as possible.
Maintain correct tire pressures. Refer to
page 29.<

BatteryBattery careThe 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. 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.<

Battery FusesCharging the battery Charge the battery in the vehicle only
when the engine is not running.
Before performing any work on
the electrical system, disconnect
the cable from the negative terminal. If
you do not, short circuits can cause 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 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
3 months. Also recharge the battery
before it is reinstalled. If this is not
done, the battery will not be service-
able. Every time the battery is drained,
especially 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
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.
Read and comply with the information
on page 138 covering this subject.<
If an electrical accessory should fail,
switch it off and check the fuse. In 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 is burned through ("blown"),
the metal strip will have melted and
separated; replace it with a new fuse
of the same ampere rating (color
code).460de062

Do not use spray starter fluids to start
the engine.
If the battery is drained, the engine can
be started using two jumper cables and
another vehicle's battery. Use only
jumper cables with fully insulated grips
on the terminal clamps.
Do not touch the parts conducting
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 short circuit risk!
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 auxiliary terminal for
jump-starting is identified by a "+"
sign. Refer to the illustration. Remove
the cover by pulling the tab (arrow 1).
5 Then connect the negative terminals.
Attach the cable to either the support
vehicle's negative battery terminal (Ð),
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 if
you assist in jump-starting another
vehicle. If you do not, there is a risk of
injury caused by spark generation at the
battery.<460de123
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 drained battery to
recharge.
8 Before disconnecting the jumper
cables from your BMW, turn on 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
accessories.
9 Then disconnect the jumper cables in
reverse sequence.
Depending on the reason for the
malfunction, recharge the battery.
Jump-starting

Tire Pressure Control (RDC)
*
This system regularly checks tire pres-
sure and monitors all four tires even
while driving, so you do not have to.
Behind the valve stem in every wheel,
there is an electronic chip which is
designed for severe-duty applications
and long service life. It contains a pres-
sure sensor, a transmitter and a battery.
The pressure is measured in extremely
short time intervals and then transmitted
by a radio signal. If an irregularity is
detected, the transmission rate is
increased. 463de006
There is an antenna located right near
every wheel in the vehicle body. This
antenna picks up signals from its
respective wheel. A central electronics
system evaluates the quadruple signals
which it receives and forwards any
changes.
The RDC provides an important contri-
bution to driving safety.
