Lamps and bulbsThe lamps and bulbs make essential
contributions to the safety of your vehi-
cle. Therefore, comply fully with the fol-
lowing instructions during bulb replace-
ment. 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 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.
Before working on the electrical
system, switch off the electrical
accessory you are working on or dis-
connect the cable from the negative
terminal of the battery. Failure to
observe this precaution could result in
short circuits.
To prevent injuries and damage, com-
ply with any instructions provided by
the bulb manufacturer.<

H7 bulb, 55 watts
The H7 bulb is pressurized. There-
fore, wear safety glasses and pro-
tective gloves. Failure to comply with
this precaution could lead to injury if the
bulb is damaged.<
1. Turn the two release catches at the
front to the left – see arrow – to
remove the bulb holder
2. Remove and replace the bulb.
When cleaning the headlamps,
please follow the instructions in
the Caring for your vehicle brochure.<
Xenon lampsThe service life of these bulbs is very
long and the probability of a failure is
very low, provided that they are not
switched on and off an unusual number
of times. If one of these bulbs should
nevertheless fail, it is possible to con-
tinue driving with great caution using
the fog lamps, provided local traffic
laws do not prohibit this.
Because of the extremely high
voltages involved, any work on the
xenon lighting system, including bulb-
changing, should be carried out by
technically-qualified personnel only.
Otherwise, there is a risk of fatal
injury.<

Changing a wheel
Safety precautions in the event of
a flat tire or wheel change:
Stop the vehicle as far as possible from
passing traffic. Park on a firm, flat, sur-
face. Switch on the hazard warning
flashers. Turn the steering wheel to the
straight-ahead position and engage the
steering lock. Shift into 1st or Reverse,
or if you have an automatic transmis-
sion, position the selector lever in Park,
and engage the parking brake.
All passengers should be outside the
vehicle and well away from your imme-
diate working area, behind a guardrail,
for instance.
If a warning triangle or portable hazard
warning lamp is available, set it up on
the roadside at an appropriate distance
from the rear of the vehicle. Comply
with all local safety guidelines and reg-
ulations.
Change the wheel only on a level, firm
surface which is not slippery. Avoid
jacking the vehicle on a soft or slippery
support surface – snow, ice, loose
gravel, etc. – as either the vehicle or the
jack could slip sideways.
Position the jack on a firm support sur-
face.
Do not place wooden blocks or similar
objects under the jack. They could pre-
vent the jack from extending to its full
height and reduce its support capacity.
Do not lie under the vehicle or start the
engine when the vehicle is supported
by the jack. There is otherwise a risk of
fatal injury.<

BatteryMaintenanceThe battery is absolutely maintenance-
free, that is, the original electrolyte will
normally last for the service life of the
battery under moderate climatic condi-
tions.
Please consult your BMW center
whenever you have any questions
concerning the battery. Since the bat-
tery is absolutely maintenance-free, the
following is for your information only.<
Never disconnect the battery
when the engine is running; the
ensuing voltage surge would seriously
damage the vehicle's onboard elec-
tronic systems. cle, leave the engine off at all times.
Connect the charge cables to the termi-
nals in the engine compartment. For
terminal locations, refer to Jump-start-
ing on page 147.
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 against tilting during trans-
port.<
FusesYou will find the fuses and information
on their respective allocation in the
glove compartment behind a panel with
two snap clips.
Do not attempt to repair a blown
fuse or replace it with a fuse
having a different color or amperage
rating. To do this could cause a fire in
the vehicle resulting from a circuit over-
load.<

147 Giving and receiving assistance
Jump-startingWhen your battery is discharged, you
can use two jumper cables to start your
vehicle with power from the battery in a
second vehicle. You can also use the
same method to help start another
vehicle. Only use jumper cables with
fully insulated handles on the terminal
clamps.
Do not touch high-voltage wiring
and cables on a running engine.
Contact with components carrying high
voltage can be harmful or fatal. Care-
fully observe the following instructions
to avoid personal injury and/or damage
to one or both vehicles.<
1. The battery in the support vehicle
must also be rated at 12 volts. This
information is provided on the battery
label
2. Stop the engine of the support vehi-
cle and switch off all electrical com-
ponents in both vehicles – except for
the hazard warning flashers of the
support vehicle
3. Make absolutely certain that there is
no contact between the bodywork of
the two vehicles – short circuit haz-
ard
4. The auxiliary jump-starting terminal
located in your BMW's engine com-
partment acts as the positive battery
terminal. The cover of this auxiliary
terminal is marked with a + sign.
Remove by pulling the tab – see
arrow 1.
Start by connecting the jumper cable
from the positive terminal of the dis-
charged battery to the positive termi-
nal of the support battery
5. Then connect the negative terminals
using the other jumper cable. First
connect one end to the negative bat-
tery terminal or to a suitable ground
on the support vehicle. Then connect
the other end to the negative battery
terminal or to a suitable ground on
the vehicle being started.
Your BMW is equipped with a special
nut for this purpose – see arrow 2
Always adhere to this sequence
when connecting jumper cables;
failure to observe this procedure can
lead to sparks at the battery terminals
and pose an injury hazard.<
6. Start the engine of the support vehi-
cle and let it run for several minutes
at a slightly elevated engine idle
speed
7. Start the engine of the other vehicle
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.

Towing the vehicleTowing eyeletThe screw-in towing eyelet is stored in
the onboard tool kit; be sure that it
remains in the vehicle at all times. It is
designed for installation in the tow
sockets located at the front and rear of
the vehicle, and is intended for towing
on paved road surfaces only. The tow-
ing eyelet should not be used to pull a
vehicle out of deep snow, mud, sand,
etc. Always observe all applicable tow-
ing laws and regulations.
Access to tow socketsFront:
Press out the cover panel with a screw-
driver inserted in the recess at the top.

truck>Do not tow with sling-type equipment
>Use wheel-lift or flatbed equipment
>Please comply with applicable state
towing laws.
Never allow passengers to ride in
a towed vehicle for any reason.
Never attach tie-down hooks, chains,
straps, or tow hooks to tie rods, control
