Caring for your car
153n
Window care
Water and dirt-repelling windshield (refer
also to page 191).
The effectiveness of the coating is not
impaired by the wax used in car washes
or by windshield-washer additives.
Depending on the frequency of use of
the windshield wipers as well as on environmental
factors, the coating of the
windshield is subject to natural wear.
As a result, the beneficial characteristics
of the coating gradually diminish.
After approx. 12,400 to 15,500 miles
(approx. 20,000 to 25,000 km), the
windshield begins to resemble more
and more a standard windshield.
The coating can be renewed by your
BMW center.
You can use window and glass cleaner
to clean interior window surfaces and
mirrors without streaking. Never use
polishing pastes or abrasive (quartz)
cleansers on mirror lenses.
Break-resistant security glass
The glass used for the side windows is
designed to provide resistance to
breakage and protection against vandalism.
These break-resistant windows
contain several layers of a transparent
plastic film which is sandwiched between
the inner and outer glass panes.
There is also one additional plastic film
on the inside of the glass pane (facing
the passenger compartment). This film
prevents shards of glass from spreading
into the passenger compartment if
the window is shattered.
Please observe the following precautions
pertaining to this film
when caring for the interior glass surfaces:
> The film is not scratch-resistant. For
this reason, do not touch the glass
with sharp objects which could damage
the film
> Clean the glass with clean water. If
necessary, you may also use regular
household window cleaners. Wipe
the cleaner off immediately.
Do not use window cleaners containing
solvents or abrasives. These
cleaners can mar the film
> Do not apply any self-adhering decals,
adhesive labels or other stickers
with tape to the inner window surface
> Do not apply colored films to the inside
surfaces of the side windows
> If the windows are fogged or iced
over in cold or humid climates, do not
use an ice scraper or ice-removing
sprays to clean them. Start the engine
and refer to the instructions for
defrosting the door windows.<
