windshield washer system
The filling capacity is approx. 4.7 US
quarts (4.5 liters) for the windshield
washer system or approx. 6.3 US
quarts (6.0 liters) together with the
headlamp washer system.
Fill with water and - when needed - with
a washer antifreeze (according to man-
ufacturer's recommendations).
We recommend that you mix the
washer fluid before adding it to
the reservoir.< 380de082
Antifreeze agents or intensive
windshield cleaning agents for the
washer systems are highly flammable.
For this reason, keep them away from
sources of flame and store them only in
their original containers. Store them so
that they are inaccessible to children.
Comply with the instructions on the
containers.<
Windshield washerThe spray from the nozzles should be
directed so as to ensure effective
cleaning, even at high speeds.
Use a needle to adjust the nozzles as
required, or have them adjusted at your
authorized BMW center.Headlamp washer systemHave the nozzles adjusted by your
BMW center as required.

Caring for your carWashing your carYou can have your new BMW washed
in an automatic car wash. Car wash
systems that do not employ brushes are
preferable.
Wipe away tough dirt and loosen and
remove dead insects before washing
the car.
To prevent spots, avoid washing when
the hood is still warm, or immediately
after and during exposure to strong
sunlight.
When using an automatic car wash, be
sure that:
>The car wash system is suited for the
dimensions of your vehicle
>No damage will occur on vehicles
with attached body accessories (such
as spoilers or antennas). If you are
uncertain, consult the manager of the
car wash
>The wheels and tires of your vehicle
cannot be damaged by the convey-
ance devices of the car wash system
>The vehicle is cleaned with minimum
brush pressure, and that ample water
is available for washing and rinsing.Vehicles with rain sensor
*:
Clean the windshield regularly. Wax
from automatic car washes or insects,
for example, can cause malfunctions in
the function of the rain sensor.
Turn the rain sensor off in auto-
matic car washes. If you do not,
damage may occur if the wipers switch
on unintentionally.<
Parts of the car which are inaccessible
to the automatic washer - such as door
sills, door and hood edges, etc. -
should be cleaned by hand.
In the winter months, it is especially im-
portant to ensure that the car is washed
on a regular basis. Large quantities of
dirt and road salt are difficult to remove,
and they also cause damage to the ve-
hicle.
If spray wands or high-pressure
washers are used, be sure to
maintain an adequate distance between
the spray source and the vehicle's sur-
face.
Inadequate distance and excessive
pressure can damage or weaken the
finish, making it more susceptible to
subsequent attack. In addition, mois-
ture could penetrate to vehicle compo-
nents, leading to long-term damage.<
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 – never
use a scraper.<
After washing the car, apply the
brakes briefly to dry them. Braking
efficiency might otherwise be reduced
by the moisture, and the brake rotors
could also be corroded.<

Lamps and bulbsThe 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, thus reducing 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.<

Xenon lamps
*
The 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 traffic laws in
your area do not prohibit this.
Because of the extremely high
voltages involved, any work on the
lighting system should be carried out by
technically-qualified personnel only.
Otherwise, there is a risk of fatal injury.<

Xenon lamps
*
The xenon lamps light up the side and
front areas of the vehicle with signifi-
cantly more brightness and uniformity
than the traditional halogen lamp.
In a xenon lamp,
an electric arc re-
places the filament in order to generate
intense illumination. A gas mixture in a
quartz piston with metal vapor is ignited
by a high electric voltage. The arc that
is generated is then sustained by a
lower voltage. When the lamp is turned
on there is a brief period of high inten-
sity. Maximum brightness is attained in
approx. 15 seconds.
390de134
Xenon lamps
provide significantly-im-
proved visibility, especially during ad-
verse weather conditions and driving
situations (driving at night in heavy rain
or through road repair areas where
there are no lanemarkers, for instance).
Vehicles with xenon lamps are
equipped with automatic-dynamic
headlamp range control. As a result, the
highway is always optimally lighted, re-
gardless of load conditions, and drivers
in oncoming traffic are not blinded.
Xenon lamps make a significant contri-
bution to highway safety since other
highway users, bicyclists and motorcy-
clists in the right lane, and pedestrians
are more easily detected.
