Caring for your carExterior finish To provide effective corrosion protec-
tion, multilayer paintwork is applied at
the factory. Cataphoretic immersion
priming techniques are supplemented
using special body-cavity protectants,
with the application of specially-devel-
oped and extensively tested materials.
A layer of flexible PVC is first applied to
the undercarriage. Following this, a
comprehensive undercoating treatment
with a wax-based protectant is applied.
Regular maintenance makes an impor-
tant contribution to maintaining the
safety and resale value of your vehicle.
Increasing awareness of the effects of
harmful environmental factors on vehi-
cle finishes have led paint and vehicle
manufacturers to initiate ongoing pro-
grams designed to further improve the
durability of their finishes. Despite this,
environmental factors that occur locally
or regionally can have negative effects
on the finish of your vehicle. These
should guide you in determining the fre-
quency and extent of your efforts to
maintain the vehicle finish.
Depending upon material and type
of impact (perforation of paint layer),
physical stresses from sand, road salt,
gravel, etc., can cause corrosion to
start extending beneath the finish, start-
ing at the point of impact.Road dirt, tar spots, dead insects, ani-
mal droppings (strong alkali concentra-
tion) and tree excretions (resins and
pollen) all contain substances capable
of causing damage when allowed to re-
main on the finish of your car for any
period of time (spots, etching, flaking,
separation in the top coat).
In industrial areas, deposits of flue dust,
lime, oily soot, precipitation containing
sulfur-dioxide (acid rain) and other envi-
ronmental pollutants will damage the
car's finish unless adequate care is pro-
vided – even though this generally lim-
ited to the outside horizontal surfaces.
In coastal regions, high levels of atmo-
spheric salt and humidity promote cor-
rosion.
In tropical zones temperatures of over
1007 (406) in the shade prevail, in
addition to heavy ultraviolet radiation
and high humidity. Under those circum-
stances light colored paints reach tem-
peratures of up to 1807 (806) and
dark paints up to 2507 (1206).
Caring for the vehicle finish Regular washing is a preventive mea-
sure against long-term effects from
substances that are harmful to the vehi-
cle's finish, especially if you drive your
vehicle in areas with high levels of air
pollution or aggressive natural sub-
stances (tree resins, pollen).
Nevertheless, you should immediately
remove especially aggressive sub-
stances. Failure to do so can lead to
changes in the paint's chemical struc-
ture or to discoloration. Gasoline spilled
during refueling, oil, grease and brake
fluid should always be cleaned away
immediately, as should bird droppings.
All of these substances cause damage
to the finish.
Any contamination remaining on the
surface of the vehicle will be especially
conspicuous after washing. Use clean-
ing fluid or alcohol with a clean cloth or
cotton pad to remove. Remove tar
spots with tar remover. After cleaning,
the affected areas should be waxed to
ensure continued protection.

Battery
A highly-explosive gas is gener-
ated when the battery is
charged.
If you happen to get acid in your
eyes, rinse thoroughly for 15 min-
utes with clear water. Consult a
physician immediately. Rinse your skin
or clothing with plenty of water if you get
acid spray on them. If electrolyte is acci-
dentally ingested, consult a physician
immediately.
In order to protect the battery
case from ultraviolet radiation,
do not place it in direct sunlight.
A discharged battery can freeze. Store
the battery in areas where temperature
remains above freezing.
Battery careThe battery is completely maintenance-
free, as per DIN 43 539/2; that is, the
amount of acid put in the battery origi-
nally will normally last for the service life
of the battery.
Charge conditionWith the help of the "Magic Eye", a
hydrometer, you can read the battery's
charge state:
>Green: Adequate charge.
>Black: Not adequately charged. The
battery must be recharged. Please
contact your authorized BMW center
for additional information.
>Yellow: Replace the battery.
The service life specified for the
battery can be achieved only if it is
always kept adequately charged. If the
vehicle is primarily used for stop-and-
go traffic, be sure to check the charge
state often.<460de252
Removal and installation
Do not disconnect the battery
cables when the engine is run-
ning, otherwise the ensuing voltage
surge will damage the vehicle's on-
board electronics.
Do not alter the positive terminal wiring
in any way, otherwise the safety battery
terminal's safety function will no longer
be guaranteed. Repair and disposal are
to be performed exclusively by trained
technicians.<
When removing the battery, disconnect
the cable on the negative terminal first,
then the cable on the positive terminal.
Loosen the center adjusting screw on
the battery retaining strap (use the
screwdriver included with the onboard
tool kit) and disconnect the strap.
When installing a battery, connect the
positive terminal first, then connect the
negative terminal.
When installing a battery, be sure
that it is mounted properly and
that the retaining bracket is installed
with the center adjustment screw. If this
is not done, the battery will not be ade-
quately secured in case of an acci-
dent.<

Self-diagnostics All of the important electrical and elec-
tronic systems in the vehicle are tested
regularly and automatically – the driver
does not have to perform any extra op-
erations or adjustments.
The indicator lamps also come on briefly
after the ignition has been turned on.
While you are driving, the functional
status of the actuator motors (for the
windshield wipers, power windows,
seats, sunroof, etc.) is constantly ana-
lyzed by current measurements in their
relays. 462de258
In the same manner, the electrical resis-
tance of the airbag ignition generators
and all of the remaining airbag compo-
nents is measured at all times. Any fault
in this system would be detected imme-
diately by a current fluctuation that
would necessarily accompany it. The
fault would be indicated immediately by
the airbag warning lamp.
Even after you shut off the engine, the
overall functional status of your vehicle
is monitored. For example, all of the
flaps of the heating and ventilation sys-
tem travel to the nearest limit position.
This action ensures that the system will
be able to provide defrosting, regard-
less of other circumstances (if a mal-
function in the heating or ventilation
system should occur during the night
while the vehicle is parked, for in-
stance).
A calibration cycle runs every tenth time
the engine is shut off. During this cycle,
the actuator motors of all the heating
and ventilation flaps travel to their limit
stops in both directions. The limit posi-
tions and the return travel paths are
checked in this manner in order to en-
sure that appropriate adjustments for
the operating elements can be made at
any time.You will hear the sounds of the air flaps
as the heater/ventilation system carries
out its self-diagnostic functions after
the ignition is shut off. All of the other
self-diagnostics functions operate si-
lently in the background.
Any faults detected during these self-
diagnostics can be read out by your
authorized BMW center during the next
regularly-scheduled maintenance and
corrected with a minimum of time.
