CoolantVehicle features and optionsThis 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.
Information WARNING
With the engine hot and the cooling sys‐
tem open, coolant can escape and lead to
burns. There is risk of injuries. Only open the
cooling system with the engine cooled down.◀
WARNING
Additives are harmful and incorrect addi‐
tives can damage the engine. There is risk of
injuries and risk of property damage. Avoid the
contact of articles of clothing, skin or eyes with
additives. Do not swallow any additives. Use
suitable additives only.◀
Coolant consists of water and additives.
Not all commercially available additives are
suitable for the vehicle. Information about suit‐
able additives is available from a dealer’s serv‐
ice center or another qualified service center or
repair shop.
Coolant level
General information
Vehicles with gasoline engine feature two
cooling circuits. Always check the coolant lev‐els of both coolant reservoirs and refill as
needed.
The coolant level is indicted using minimum
and maximum markings. Depending on the
coolant reservoir, the minimum and maximum
markings are located at different locations.
Overview
Opening the hood, refer to page 272
Depending on the engine installation, the cool‐
ant reservoir is located on the right side or the
left side of the engine compartment, refer to
page 271.

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 your 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.
Detailed information on service requirements,
refer to page 119, 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 an optimized maintenance scope
for your vehicle.
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.

Diagnosis
Information CAUTION
Improper use of the socket for Onboard
Diagnosis can lead to vehicle malfunctions.
There is risk of property damage. The manu‐
facturer of your vehicle strongly recommends
access to the socket for Onboard Diagnosis be
limited to a dealer's service center, another
qualified service center or repair shop or other
authorized persons.◀
Position
There is an OBD socket on the driver's side for
checking the primary components in the vehi‐
cle's emissions.
Emissions
▷The warning lamp lights up:
Emissions are deteriorating. Have
the vehicle checked as soon as
possible.▷The warning lamp flashes under certain
circumstances:
This indicates that there is excessive mis‐
firing in the engine.
Reduce the vehicle speed and have the
system checked immediately; otherwise,
serious engine misfiring within a brief pe‐
riod can seriously damage emission con‐trol components, in particular the catalytic
converter.Seite 280MobilityMaintenance280

▷Have all vehicle occupants get out of the
vehicle and ensure that they remain out‐
side the immediate area in a safe place,
such as behind a guardrail.▷If necessary, set up a warning triangle or
portable hazard warning lamp at an appro‐
priate distance.▷Perform wheel change only on a flat, solid
and slip-resistant surface. On soft or slip‐
pery ground, e.g., snow, ice, tiles, etc., the
vehicle or vehicle jack can slip away to the
side.▷Do not place wood blocks or similar items
under the vehicle jack; otherwise, it cannot
reach its carrying capacity because of the
restricted height.▷If the vehicle is raised, do not lie under the
vehicle and do not start the engine; other‐
wise, a fatal hazard exists.
