Roof-mounted luggage rack*A special roof-rack system is available
as an optional extra for your BMW.
Please observe the precautions
included with the installation instruc-
tions.AnchoragesAccess to the anchorages:
To fold up the covers – see arrow –
please use the tool provided with the
roof-rack system.Loading and driving notesRoof-mounted luggage racks raise the
center of gravity of the vehicle when
they are loaded. For this reason, they
exercise a major effect on the vehicle's
handling and steering response.
You should therefore always remember
not to exceed the approved roof load
capacity, the approved gross vehicle
weight or the axle loads when loading
the rack. These weights are listed under
Technical data on page 154.
Make sure that the load is not too bulky,
and attempt to distribute it evenly.
Always load the heaviest pieces first so
that they are at the bottom. Be sure that
adequate clearance is maintained for
raising the sliding/tilt sunroof, and that
objects do not project into the opening
path of the tailgate.
Secure the roof-mounted luggage cor-
rectly and securely to prevent it from
shifting or being lost during driving.
Drive smoothly and avoid sudden
acceleration and braking. Do not corner
at high speeds.
The roof-mounted luggage rack and the
roof load increase the aerodynamic
resistance: increased fuel consumption
and additional stress on the vehicle's
body are the result.

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.<
Low beams and high beamsEngine compartment, left side:
1Low beams
2High beams
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.<
