Continuing the tripDo not exceed the maximum permissible
speed of 50 mph/80 km/h.
Reinitialize the Flat Tire Monitor.
Reinitialize the Tire Pressure Monitor.
Replace the defective tire and the sealant con‐
tainer of the Mobility System as soon as possi‐
ble.
Snow chains Fine-link snow chains
Only certain types of fine-link snow chains
have been tested by the manufacturer of the
vehicle, classified as road-safe and approved.
Information about the approved snow chains
are available from the service center.
Use
Use only in pairs on the rear wheels, equipped
with the tires of the following size:▷155/70 R 19
Follow the snow chain manufacturer's instruc‐
tions.
Make sure that the snow chains are always
sufficiently tight. Retighten as needed accord‐
ing to the chain manufacturer's instructions.
Do not initialize the Flat Tire Monitor after
mounting snow chains, as doing so may result
in incorrect readings.
Do not initialize the Tire Pressure Monitor after
mounting snow chains, as doing so may result
in incorrect readings.
When driving with snow chains, briefly activate
Dynamic Traction Control if needed.
Maximum speed with snow chains Do not exceed a speed of 30 mph/50 km/hwhen using snow chains.

Hood Hints Working under the hood
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 work is not carried out properly, there is a
danger of subsequent damage and related
safety hazards.◀

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.
Hints Danger of burns from hot engine
Do not open the cooling system while
the engine is hot; otherwise, esliding coolant
may cause burns.◀
Suitable additives
Only use suitable additives; otherwise,
engine damage may occur. The additives are
harmful to your health.◀
Coolant consists of water and additives.
The vehicle's cooling circuits are filled with dif‐
ferent types of coolant. Do not mix the differ‐
ent types of coolant.
Not all commercially available additives are
suitable for the vehicle. Information about the
suitable additives are available from the service
center.
Coolant reservoir The vehicle has two coolant reservoirs that are
located under the hood.
To ensure the operational reliability of the vehi‐
cle, always check the coolant level of both
coolant reservoirs.
Open hood, refer to page 180.1Coolant reservoir for climate control2Coolant reservoir for drive
Coolant level
Coolant reservoir for climate control
Checking
1.Allow the drive to cool down.2.Turn the lid of the coolant reservoir slightly
counterclockwise to allow any excess
pressure to dissipate, then open it.3.Check the coolant level.
The coolant level is correct if it lies be‐
tween the minimum and maximum marks
in the reservoir.
Adding
1.Slowly add coolant up to the specified
level; do not overfill.Seite 181CoolantMobility183

2.Close cap.3.Have the cause of the coolant loss elimi‐
nated by the service center as soon as
possible.

The marks are on the side of the coolant
reservoir. The coolant level is correct if it
lies between the minimum and maximum
marks.

Disposal
Comply with the relevant environmen‐
tal protection regulations when dispos‐
ing of coolant and coolant additives.

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.
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.
Note Maintenance and repairs
Have maintenance and repair work per‐
formed only by a service center or a workshop
that works according to BMW specifications
with appropriately trained personnel. Other‐
wise, there is the risk of fatal injury from elec‐
trocution due to the high-voltage system's
high voltage.◀
Condition Based Service
CBS
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 82, can be displayed on the Con‐
trol Display.
For service data 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 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 service center update the
time-dependent maintenance procedures,
such as checking brake fluid and, if needed,
changing the engine oil and the microfilter/
activated-charcoal filter.

Please consult your Service and Warranty In‐
formation Booklet for US models and Warranty
and Service Guide Booklet for Canadian mod‐
els for additional information on service re‐
quirements.
Maintenance and repair should be performed
by your service center. Make sure to have reg‐
ular maintenance procedures recorded in the
vehicle's Service and Warranty Information

els. These entries are proof of regular mainte‐
nance.
Socket for OBD Onboard
Diagnosis
Note Socket for Onboard DiagnosisThe socket for onboard diagnostics may
only be used by the service center or a work‐
shop that operates in accordance with the
specifications of the vehicle manufacturer with
correspondingly trained personnel and other
authorized persons. Otherwise, use may result
in operating problems for the vehicle.◀
Position
Located on the driver's side is an OBD socket
for reading the vehicle data. On vehicles with
Range Extender, additional components are
checked that are critical for its emissions mix.
Emissions
Applies to vehicles with Range Extender.
▷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 184MobilityMaintenance186

the service center if you are unfamiliar those or
if they have not been described here.
You can obtain a selection of replacement
bulbs at the service center.
Danger of burns
Only change bulbs when they are cool;
otherwise, there is a danger of getting
burned.◀
Working on the lighting system
When working on the lighting system,
you should always reel off the lights affected to
prevent short circuits.
To avoid possible injury or equipment damage
when replacing bulbs, observe any instructions
provided by the bulb manufacturer.◀
Do not touch the bulbs
Do not touch the glass of new bulbs with
your bare hands, as even minute amounts of
contamination will burn into the bulb's surface
and reduce its service life.
Use a clean tissue, 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.
Do not remove the covers
Do not remove the covers, and never
stare into the unfiltered light for several hours;
otherwise, irritation of the retina could result.◀
Headlight glass
Condensation can form on the inside of the ex‐
ternal lights in cool or humid weather. When
driving with the light switched on, the conden‐
sation evaporates after a short time. The head‐
light glass does not need to be changed.If the headlights do not dim despite driving
with the light switched on, increasing humidity
forms, e. g. water droplets in the light, have the
service center check this.
Headlight setting The headlight adjustments can be affected by
changing lights and bulbs. Have the head‐
lights' settings checked and corrected by serv‐
ice after a replacement.
