1 Intermittent mode or
rain sensor*Intermittent mode:
You can set the wipe interval to four
stages with rotary dial 7.
In addition, the wipe interval is varied
automatically depending on road
speed.
Rain sensor:
When the rain sensor is activated, the
windshield wiper is controlled automati-
cally, depending on the degree of wet-
ness of the windshield (in both snow
and rain). You do not have to be con-
cerned with switching the windshield
wiper on or off or adjusting the wipe in-
terval between intermittent and full
wipe. Instead, you can concentrate fully
on the traffic conditions. This is espe-
cially important under adverse weather
conditions.
The rain sensor is positioned on the
windshield, directly ahead of the inte-
rior rearview mirror.
To activate the rain sensor:
From ignition key position 1 and up,
move the lever to position 1. The wipers
travel once across the windshield,
regardless of the weather.

174nCaring for your car
Window care
You can use window and glass cleaner
to clean inside window surfaces and
mirrors without smearing and streaking.
Never use polishing pastes or abrasive
(quartz) cleansers on mirror lenses.
When caring for break-resistant
security glass
*, observe the fol-
lowing instructions:
The inner surface of the side windows
is coated with a plastic film. For this
reason, do not affix any decals or adhe-
sive stickers on the inside of these win-
dows unless they are to be placed there
permanently.
Wash the glass with clean water. If nec-
essary, you may add a commercially-
available mild household cleaner. Do
not use abrasive cleaners.
If the windows are fogged or iced over,
treat them with an anti-misting cloth or
a deicer spray – do not use an ice
scraper. <
Clean the wiper blades with soapy wa-
ter. The wiper blades should be re-
placed twice a year, before and after
the cold season.
Use only wiper blades which have
been approved by BMW. <
Caring for other vehicle
components and materials
Light-alloy wheels should be treated
with alloy wheel cleaner, especially
during the winter months. However, do
not use aggressive products contain-
ing acids, strong alkalis or abrasives.
Do not use steam cleaners operating at
temperatures above 140 7 (60 6).
(Follow the manufacturer's instruc-
tions.)
If your vehicle has chrome parts
* such
as window moldings, door handles or
other items, clean these parts carefully
with ample clean water, especially if
they have an accumulation of road salt.
Use a chrome polish for an additional
treatment.
Plastic components, vinyl upholstery,
headliners, lamp lenses, the clear cover
of the instrument cluster and compo-
nents with a sprayed dull black surface
can be cleaned with water (add plastic
cleaner as required). Do not allow mois-
ture to soak through the seats or head-
liner. Never use solvents such as lac-
quer thinner, heavy-duty grease
remover, fuels, etc. Rubber components should be cleaned
with water only; a rubber treatment or
silicone spray may also be applied.
The safety belts should be cleaned with
a mild soap and water solution without
being removed from the vehicle. Never
attempt chemical or dry cleaning, as
damage to the belt fabric could result.
After cleaning, never allow the inertia
reel to retract the belts until they are
completely dry. Dirty safety belts pre-
vent the inertia reel mechanism from
retracting the strap properly, and thus
constitute a safety hazard.
Heavily soiled floor carpets and mats
*
can be cleaned with an interior cleaner.
The floor mats can be removed from
the vehicle for cleaning.
Please use only a damp cloth to clean
wooden fascia panels and components.
Follow up by drying with a soft cloth.
Use cleaning and car-care
products that you can obtain
at your BMW center. <

Overview
211nDSP sound system*Mirrors with automatic dimmer*
The DSP professional premium sound
system features a special amplifier
combined with Digital Sound Process-
ing (DSP) and integrated speakers to
surround you with crisp, true-to-life
sound reproduction.
The speaker system's subwoofers,
woofers, midrange speakers and tweet-
ers furnish you with an impressively full-
bodied listening experience. The indi-
vidual components are oriented so as
to produce the aural sensation that you
would experience facing the stage in a
concert hall. The system also automati-
cally adjusts the bass and treble set-
tings to compensate for changes in vol-
ume and vehicle speed.
390de109
The interior and exterior mirrors with
automatic dimming feature reduce the
glare from following traffic by adapting
the intensity of the reflected images to
correspond to levels of light registered
by the unit's sensors. The mirrors revert
to their undimmed setting as soon as
the light source disappears.
One sensor is mounted on the front
of the interior mirror housing and is
designed to monitor light levels in the
area immediately forward of the vehicle.
A second sensor is integrated within
the mirror's glass.
390de113
The electronic control system operates
by comparing the respective levels of
luminous intensity in front of and behind
the car. The difference provides the
basic parameter used to modulate an
electrical current and induce chemical
changes in a semisolid layer incorpora-
ted in the lens.
The semisolid reacts chemically to this
electrical current, thus providing infi-
nitely-variable dimming of the mirror
(electrochromic technology).
As a result, it is no longer necessary
to dim the mirror manually, and the
driver can maintain full concentration
on traffic.
