service BMW X3 2017 Service Manual

MaintenanceVehicle features and options
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
BMW maintenance system The maintenance system indicates required
maintenance measures, and thereby provides
support in maintaining road safety and the op‐
erational reliability of the vehicle.
In some cases scopes and intervals may vary
according to the country-specific version. Re‐
placement work, spare parts, fuels and lubri‐
cants and wear materials are calculated sepa‐
rately. Further information is available from a
dealer’s service center or another qualified
service center or repair shop.
Condition Based ServiceCBS
Sensors and special algorithms take into ac‐
count the driving conditions of the vehicle.
Based on this, Condition Based Service recog‐
nizes the maintenance requirements.
The system makes it possible to adapt the
amount of maintenance corresponding to your
user profile.
Information on service requirements can be
displayed on the Control Display.Service data in the remote control
Information on the required maintenance is
continuously stored in the remote control. The dealer’s service center can read this data out
and suggest a maintenance scope for the vehi‐
cle.
Therefore, hand the service advisor the remote
control with which the vehicle was driven most
recently.
Storage periods Storage periods during which the vehicle bat‐
tery was disconnected are not taken into ac‐
count.
If this occurs, have a dealer's service center or
another qualified service center or repair shop
update the time-dependent maintenance pro‐
cedures, such as checking brake fluid and, if
necessary, changing the engine oil and the mi‐
crofilter/activated-charcoal filter.

Information
Lights and bulbs
Lights and bulbs make an essential contribu‐
tion to vehicle safety.
The manufacturer of the vehicle recommends
that you have appropriate work performed by a
dealer’s service center or another qualified
service center or repair shop if you are unfami‐
liar with it or if it has not been described here.
A spare lamp box is available from a dealer’s
service center or another qualified service cen‐
ter or repair shop.
WARNING
Bulbs can get hot during operation. Con‐
tact with the bulbs can cause burns. There is a
risk of injuries. Only change bulbs after they
have cooled off.◀
WARNING
Work on switched-on lighting systems
can cause short circuits. There is a risk of inju‐
ries or a risk of property damage. When work‐
ing on the lighting system, switch off the lamps
in question. If necessary, heed the bulb manu‐
facturer's instructions.◀
DANGER
There can be high voltage in the lighting
system. There is danger to life. The manufac‐
turer of your vehicle recommends that the
work on the lighting system including bulb re‐
placement be performed by a dealer’s service
center or another qualified service center or re‐
pair shop.◀
CAUTION
Dirty bulbs have a reduced service life.
There is a risk of property damage. Do not hold
new bulbs with your bare hands. Use a clean
cloth or something similar, or hold the bulb by
its base.◀
Light-emitting diodes (LEDs)
Some items of equipment use light-emitting
diodes installed behind a cover as a light
source.
These light-emitting diodes, which are related
to conventional lasers, are officially designated as Class 1 light-emitting diodes.
WARNING
Too intensive brightness can irritate or
damage the retina of the eye. There is a a risk
of injury. Do not look directly into the head‐
lights or other light sources. Do not remove the
LED covers.◀
Headlight glass
Condensation can form on the inside of the ex‐
ternal lights in cool or humid weather. When
driving with the lights switched on, the con‐
densation evaporates after a short time. The
headlight glass does not need to be changed.
If despite driving with the lights switched on,
increasing humidity forms, e. g. water droplets
in the lamp, the manufacturer of your vehicle
recommends having it checked by a dealer’sSeite 229Replacing componentsMobility229
