The lamps and bulbs make essential
contributions to the safety of your vehi-
cle. Observe the following instructions
during bulb replacement carefully. If
you are not familiar with any of the pro-
cedures, consult your authorized BMW
center.
Do not touch the glass portion of
a new bulb with your bare hands
since even small amounts of impurities
burn in to 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 electri-
cal system, switch off the electri-
cal accessory you are working on or
disconnect the cable from the negative
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 tires Battery Driving with the space-saver
spare tire
*
Drive cautiously and do not exceed a
speed of 45 mph (80 km/h).
Be aware that vehicle handling will be
altered. Slower brake response time,
longer braking distances and changed
steering characteristics may be antici-
pated when approaching limit condi-
tions.
The changes in handling characteristics
will be even more pronounced in con-
junction with winter tires.
Only one space-saver spare tire
may be mounted. Mount a wheel
and tire with the same size and specifi-
cations as the others at the earliest
possible opportunity. Maintain correct
tire pressures. Refer to page 28.<
Battery location The battery is located at the right-rear
of the luggage compartment. Raise the
luggage compartment floor panel (refer
to page 41), and give a screwdriver or a
coin a 1/4-turn counterclockwise to
release the two fasteners plus an addi-
tional fastener in the upper-center side
trim panel. In order to remove the stor-
age tray, slide the side trim panel
slightly upward.460de176
SymbolsYou will find the following symbols on
your car battery. To avoid injury, please
comply with the corresponding precau-
tions 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.
Ensure that children keep well
away from batteries and battery
acid.
Fire, sparks, an open flame and/
or smoking are not allowed in
the vicinity of the battery. Avoid
sparks from electrical cables or electri-
cal equipment. Turn the key to position
0 in the steering lock when the battery
is disconnected or connected. Never
short-circuit the battery terminal, other-
wise you could be injured by electrical
sparks.

152n
Battery
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 min-
utes with clear water. Consult a
physician immediately. Rinse your skin
or clothing with plenty of water if you get
acid spray on them. If electrolyte is acci-
dentally 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.
Battery careThe battery is completely maintenance-
free, as per DIN 43 539/2; that is, the
amount of acid put in the battery origi-
nally will normally last for the service life
of the battery.
Charge conditionWith the help of the "Magic Eye", a
hydrometer, you can read the battery's
charge state:
>Green: Adequate charge.
>Black: Not adequately charged. The
battery must be recharged. Please
contact your authorized BMW center
for additional information.
>Yellow: Replace the battery.
The service life specified for the
battery can be achieved only if it is
always kept adequately charged. If the
vehicle is primarily used for stop-and-
go traffic, be sure to check the charge
state often.<460de252
Removal and installation
Do not disconnect the battery
cables when the engine is run-
ning, otherwise the ensuing voltage
surge will damage the vehicle's on-
board electronics.
Do not alter the positive terminal wiring
in any way, otherwise the safety battery
terminal's safety function will no longer
be guaranteed. Repair and disposal are
to be performed exclusively by trained
technicians.<
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 ade-
quately secured in case of an acci-
dent.<

Battery FusesCharging 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, or it could cause
short-circuiting, a fire or personal
injury.<
If the vehicle is to be parked longer than
4 weeks, disconnect the battery from
the vehicle's electrical system by dis-
connecting the negative terminal cable.
If you intend to store your car for longer
than six weeks: Remove the battery,
charge it and store it in a cool (but frost-
free) room. Recharge the battery every
6 months at the latest, at the very least
before each installation, or else it will be
unusable. Every time the battery is dis-
charged, especially over extended peri-
ods, its service life is reduced.
Return used batteries to a recy-
cling point or your authorized
BMW center. Maintain the battery in an
upright position for transport and stor-
age. Secure the battery against tilting in
transit.<
Storage periods during which the
battery is disconnected are not
taken into consideration by the Service
Interval Display for changing the brake
fluid.
Therefore, make sure that the brake
fluid is changed every two years at the
latest, regardless of the display. Com-
ply with the information provided on
page 127.<
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 (the
metal strip is melted and separated),
replace it with a new fuse of the same
ampere rating (color code).460de062

156n
Never 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 an-
other vehicle. Always use jumper ca-
bles with fully insulated handles on the
terminal clamps.
Contact with parts conducting
electrical current on a running
engine can be harmful or fatal.<
Carefully comply with the following in-
structions to avoid personal injury and
damage to one or both vehicles:
1 Ensure that the battery on the sup-
port vehicle is also rated at 12 volts,
and that the capacities of the two
batteries (Ah) are roughly comparable
(printed on casing)
2 Leave your battery connected to the
car electrical system
3 Make sure that there is no contact
between the bodywork of the two
vehicles – short circuit risk!
4 Start by connecting the jumper cable
from the positive terminal of the sup-
port 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 ve-
hicle that is to be started. This a spe-
cial nut that is provided on the BMW
(arrow 2)
Observe the same sequence for
connecting the jumper cables
when helping other vehicles, otherwise
there is the risk of injury if sparks gener-
ate at the battery.<462de253
6 If the battery on the support vehicle is
weak, start the engine and let it run
7 Start the engine on the vehicle need-
ing 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 re-
charge
8 Before disconnecting the jumper ca-
bles from your BMW, turn on the rear
window defroster and set the blower
to the highest speed; allow the en-
gine 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 cause of the fault,
recharge the battery.
Jump-starting

164n
Tire Pressure Control (RDC)
*
This system regularly checks tire pres-
sures and monitors all four tires even
while driving, so you don't have to.
Behind the valve stem in every wheel,
there is an extended-life electronic chip
that has a pressure sensor, a transmit-
ter and a battery. The pressure is mea-
sured in extremely short time intervals
and then transmitted by a radio signal.
If an irregularity is detected, the trans-
mission rate is increased. 462de257
Near every wheel there is an antenna in
the body that receives the signals from
all four wheels. A central electronics
system evaluates the quadruple signals
and forwards any changes. The RDC
plays an important part in driving safety.
