Lamps and bulbsThe lamps and bulbs make essential
contributions 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 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
disconnect the cable from the negative
terminal of the battery. Failure to
observe this precaution could result in
short circuits.
To prevent injuries and damage,
comply with any instructions provided
by the bulb manufacturer.<
Low and high beamsEngine compartment, left side:
1 Low beams
2 High beams
H7 bulb, 55 watts
The H7 bulb is pressurized. There-
fore, wear safety glasses and
protective gloves. Failure to comply
with this precaution could lead to injury
if the bulb is accidentally damaged
during replacement.<
1. Press the two release catches at the
front while simultaneously turning
them to the left to remove the bulb
holder
2. Remove and replace the bulb.
When cleaning the headlamps,
please observe the following:
>Do not clean by wiping with a dry
cloth (scratches). Never use abra-
sives or strong solvents to clean the
covers
>Remove dirt and contamination (such
as insects) by soaking with BMW Car
Shampoo and then rinsing with plenty
of water
>Always use a deicer spray to remove
accumulated ice and snow Ð never
use a scraper.<
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
continue 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 should be carried
out by technically-qualified personnel
only. Otherwise, there is a risk of fatal
injury.<

Lamps and bulbs Changing a wheelTailgate lamp5 watt bulb
1. Pull out the bulb holder (arrow)
2. Replace the bulb.
Safety measures 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,
surface. 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
(selector lever in Park with automatic
transmission) 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
regulations.
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
surface.
Do not place wooden blocks or similar
objects under the jack. They could
prevent 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 Ð risk of fatal injury.<
Your BMW is equipped with a spare tire
or a space-saver spare tire designed for
temporary use in maintaining the
vehicle's mobility in an emergency.
To remove the spare tire, lift the
floor panel in the cargo area
completely out, refer to page 99.<

Changing a wheel4. Loosen the lug bolts by rotating half
a turn
5. Position the jack at the jacking point
(arrows) closest to the flat tire so that
the jack base is vertically below the
jacking point and the entire surface
of the head of the jack will move into
the square recess of the jacking
point (refer to the detail in the next
illustration) when the jack is cranked
6. Jack the vehicle up until the wheel
you are changing is raised from the
ground
7. Unscrew the lug bolts and remove
the wheel
8. Remove accumulations of mud or
dirt from the mounting surfaces of
the wheel and hub. Clean the lug
bolts
9. Position the new wheel or the
space-saver spare tire on the hub
and screw at least two lug bolts
finger-tight into opposite bolt holes
10. Screw in the remaining lug bolts.
Screw in all the bolts in a diagonal
pattern
11. Lower the jack and remove it from
beneath the vehicle
12. Tighten the lug bolts securely in a
diagonal pattern
13. Wheels with full wheel covers
*:
Place the wheel cover with the
valve opening (arrow) over the
valve. Use both hands to press the
cover securely onto the rim
14. Check and correct the tire inflation
pressure at the earliest opportunity.
Vehicles with Tire Pressure Monitor
(RDC):
After mounting the spare tire or
correcting the inflation pressure,
reactivate the system, refer to
page 78 or 80.
Protect valve stems and valves from dirt
using screw-on valve stem caps. Dirty
valve stems frequently lead to slow
pressure loss.

Changing a wheel Battery Fuses
Safety tires are only possible in
conjunction with Tire Pressure
Monitor (RDC) or Flat Tire Monitor.<
If the defective wheel cannot be seen
as such immediately from the outside,
check the tire inflation pressure at all
four wheels.
Have the tires changed by your
BMW center. For safety reasons,
do not have a safety tire repaired. Your
BMW center has the information
needed for working with safety tires
and is equipped with the necessary
special tools.<
If appropriate, please consult your
BMW center to reequip your
vehicle from summer to winter tires Ð or
vice versa.<
Battery careThe 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 battery
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. vehicle, leave the engine off at all times.
Connect the charge cables to the termi-
nals in the engine compartment.
Terminal locations, refer to Jump-
starting on page 134.
Return used batteries to a recycling
point or your BMW center. Maintain
the battery in an upright position for
transport and storage. Secure the
battery against tilting during transport.<
The fuses are located in the glove
compartment behind a cover secured
by 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.<
