2012 BMW Z4 SDRIVE28I headlamp

High-beam Assistant
The concept
When the lights are switched on, this system
automatically switches the high beams on and
off. The procedure is controlled by a sensor on
the front of the interior rearview mirror. The as‐
sistant ensures that the high beams are
switched on whenever the traffic situation al‐
lows. The driver can intervene at any time and
switch the high beams on and off as usual.
Activating the High-beam Assistant1.Turn the light switch to .2.With the low beams switched on, briefly
push the turn indicator lever in the direction
of the high beam.
The indicator lamp in the instrument
cluster lights up.
When the lights are switched on, the
high beams are switched on and off automati‐
cally.
The system responds to light from oncoming
traffic and traffic driving ahead of you, and to ad‐
equate illumination, e.g., in towns and cities.

manually

To reactivate the High-beam Assistant, briefly
push the turn indicator lever toward the high
beams.
System limits
Personal responsibility
The High-beam Assistant cannot serve as
a substitute for the driver's personal judgment
of when to use the high beams. Therefore, man‐
ually switch off the high beams in situations
where this is required to avoid a safety risk.◀
The system is not fully functional in situations
such as the following, and driver intervention
may be necessary:▷In very unfavorable weather conditions,
such as fog or heavy precipitation.▷In detecting poorly-lit road users, such as
pedestrians, cyclists, horseback riders and
wagons; when driving close to train or ship
traffic; and at animal crossings.▷In tight curves, on hilltops or in depressions,
in cross traffic or half-obscured oncoming
traffic on freeways.▷In poorly-lit towns and cities and in the pres‐
ence of highly reflective signs.▷At low speeds.▷When the windshield in front of the interior
rearview mirror is fogged over, dirty or cov‐
ered with stickers, etc.
Sensor view field
The view field of the sensor is located on the
front of the interior rearview mirror.
Do not cover this area with stickers, etc.
Clean the view field, refer to page 185.
Instrument lighting
The parking lamps or low beams must be
switched on to adjust the brightness.

Use a clean tissue, cloth or something similar, or
hold the bulb by its base.◀
Light-emitting diodes LED
Light-emitting diodes installed behind translu‐
cent lenses serve as the light source for many of
the controls and displays in your vehicle.
These light-emitting diodes, which operate us‐
ing a concept similar to that applied in conven‐
tional lasers, are officially designated as Class 1
light-emitting diodes.
Do not remove the covers
Do not remove the covers, and never stare
into the unfiltered light for several hours; other‐
wise, irritation of the retina could result.◀
Headlamp glass
Condensation can form on the inside of the ex‐
ternal lamps in cool or humid weather. When you
drive with the lights switched on, the conden‐
sation evaporates after a short time. The head‐
lamp glasses do not need to be changed.
If the condensation in the headlamps does not
evaporate after trips with the lights switched on,
and the amount of moisture in the headlamps
increases, for example if water droplets form,
have them checked by your service center.
Xenon headlamps
Because of the long life of these bulbs, the like‐
lihood of failure is very low. Switching the lamps
on and off frequently shortens their life.
Do not perform work/bulb replacement on
xenon headlamps
Have any work on the xenon lighting system, in‐
cluding bulb replacement, performed only by a
service center.
Due to the high voltage present in the system,
there is the danger of fatal injuries if work is car‐
ried out improperly.◀Parking lamps, roadside parking lamps,

▷Do not rub dry and do not use abrasive or
caustic cleansers.▷Soak areas that have been soiled e.g. due to
insects, with shampoo and wash off with
water.▷Thaw ice with de-icing spray; do not use an
ice scraper.
Retractable hardtop
When you open a wet hardtop, water drops may
run into the cargo area. If necessary, remove
items from the cargo area beforehand to avoid
water stains or soiling.
After washing the vehicle
After washing the vehicle, apply the brakes
briefly to dry them; otherwise, braking action can
be reduced and corrosion of the brake discs can
occur.
Vehicle care
Car care products
BMW recommends using cleaning and care
products from BMW, since these have been
tested and approved.
Car care and cleaning products
Follow the instructions on the container.
When cleaning the interior, open the doors or
windows.
Only use products intended for cleaning vehi‐
cles.
Cleansers can contain substances that are dan‐
gerous and harmful to your health.◀
Vehicle paint
Regular care contributes to driving safety and
value retention.
Environmental influences can act on the vehicle
paint. Tailor the frequency and extent of your car
care to these influences.
Leather care
Remove dust from the leather often, using a
cloth or vacuum cleaner.
Otherwise, particles of dust and road grime
chafe in pores and folds, and lead to increased
wear and premature degradation of the leather
surface.
To guard against discoloration, such as from
clothing, provide leather care roughly every two
months.
Clean light-colored leather more frequently as
dust and dirt are more noticeable.
Use leather care products; otherwise, dirt and
grease will gradually break down the protective
layer of the leather surface.
Suitable care products are available from the
service center.
Upholstery material care
Vacuum regularly with a vacuum cleaner.
If they are very dirty, e.g., beverage stains, use a
soft sponge or microfiber cloth with a suitable
interior cleaner.
Clean the upholstery down to the seams using
large sweeping motions. Avoid rubbing the ma‐
terial vigorously.
Damage from Velcro® fasteners
Open Velcro® fasteners on pants or other
articles of clothing can damage the seat covers.
Ensure that any Velcro® fasteners are closed. ◀Seite 183CareMobility183
