Hood
Opening the hood Working in the engine compartment
Never attempt to perform any service or
repair operations on your vehicle without the necessary professional technical training.
If you are unfamiliar with the statutory guide‐
lines, have any work on the vehicle performed
only by a service center.
If this work is not carried out properly, there is
the danger of subsequent damage and related
safety hazards.◀
To avoid damage, make sure that the
wiper arms are resting against the wind‐
shield before you open the engine compart‐
ment. Do not open the engine hood before the
engine has cooled down; otherwise, injuries
may result.◀1.Pull the lever.2.Push the release lever to the right and
open the hood.Danger of injury when the hood is open
There is a danger of injury from protrud‐
ing parts when the hood is open.◀
Closing the hood
Close the hood from a height of ap‐
prox. 16 in/40 cm with momentum. It must be
clearly heard to engage.
Hood open when driving
If you see any signs that the hood is not
completely closed while driving, pull over im‐
mediately and close it securely.◀
Danger of pinching
Make sure that the closing path of the
hood is clear; otherwise, injuries may result.◀
Checking the oil level General information
Engine oil consumption depends on the driv‐
ing style and the conditions of use. A highly
sporty driving style, for example, results in
considerably higher engine oil consumption.
Therefore, regularly check the engine oil level
after refueling.
The concept
The car is equipped with an electronic engine
oil level check.
When the oil quantity reaches minimum level, a
Check Control message is displayed.

MaintenanceVehicle equipment
This chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series.Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to safety-related functions and
systems.
BMW Maintenance System
The maintenance system provides information
on required maintenance measures and thus
provides support in maintaining road safety
and the operational reliability of the vehicle.
Condition Based Service
CBS
Sensors and special algorithms take into ac‐
count the driving conditions of your vehicle.
Based on this, Condition Based Service deter‐
mines the maintenance requirements.
The system makes it possible to adapt the
amount of maintenance you need to your user
profile.
Details on the service requirements, refer to
page 78, can be displayed on the Control Dis‐
play.
Service data in the remote control
Information on the required maintenance is
continuously stored in the remote control. Your service center will read out this data and
suggest the right array of service procedures for your vehicle.
Therefore, hand your service specialist the re‐
mote control that you used 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 service center update the
time-dependent maintenance procedures,
such as checking brake fluid and, if necessary,
changing the engine oil and the microfilter/
activated-charcoal filter.

Socket for OBD Onboard
Diagnosis
Socket for Onboard Diagnosis
The socket for Onboard Diagnosis may
only be used by the service center, by work‐
shops that operate according to the specifica‐
tions of the vehicle manufacturer with appro‐
priately trained personnel, and by other
authorized persons. Otherwise, its use may
lead to vehicle malfunctions.◀
On the driver's side is an OBD socket for
checking the primary components in the vehi‐
cle emissions.
Emissions
▷The warning lamp lights up:
The emissions values are deterio‐
rating. 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.
Display of the previously described
malfunctions on Canadian models.
Fuel cap
The indicator lamp lights up.
If the fuel cap is not properly tight‐
ened, the OBD system may conclude that fuel
vapor is escaping. If the cap is then tightened,
the display should go out in a short time.Seite 242MobilityMaintenance242
