Wheels with electronics for
TPM Tire Pressure Monitor
When mounting new tires or changing from
summer to winter tires or vice versa, only use
wheels with TPM electronics, otherwise the
Tire Pressure Monitor cannot detect a flat tire,
refer to page94. Your BMW Sports Activity
Vehicle Center will be happy to advise you on
this subject.
Recommended tire brands
Certain tire makes are recommended by BMW
depending on the tire size. You can recognize
these from the clearly visible BMW marking on
the tire sidewall.
When used properly, these tires comply with
the most demanding standards for safety and
vehicle response.
Special characteristics of winter tires
BMW recommends winter tires for use in cold
winter driving conditions. Although all-season
M+S tires provide better winter traction than
summer tires, they generally fail to provide the
same levels of cold-weather performance as
winter tires.
Paying attention to speed
Always observe the maximum permissi-
ble speed for the winter tires, otherwise
tire damage may occur, which can result in acci-
dents.<
Storage
Store wheels and tires in a cool, dry place with
as little exposure to light as possible. Always
protect tires against all contact with oil, grease
and fuels. Do not exceed the maximum tire
inflation pressure indicated on the side wall of
the tire.
Rotating wheels between axles
BMW does not recommend moving the front
wheels to the rear or vice versa, as otherwise
the handling characteristics may be impaired.
Snow chains*
BMW only tests certain fine-link snow chains,
classifies them as road-safe and recommends
them. Your BMW Sports Activity Vehicle Center
can provide you with this information.
Use is only permissible in pairs on the rear
wheels.
Observe the manufacturer's instructions when
mounting snow chains. Do not exceed a speed
of 30 mph/50 km/h with the chains mounted.
After mounting snow chains, do not ini-
tialize the Flat Tire Monitor
*, as otherwise
incorrect displays can occur.
When you are driving with snow chains, it can
be beneficial to activate DTC briefly, refer to
page89.<

Maintenance
BMW maintenance system
The BMW maintenance system supports the
preservation of the traffic and operating safety
of your BMW. The service schedule also
includes operations related to the vehicle's
comfort and convenience features, such as
replacement of the filters for the inside air.
The ultimate objective is to ensure economical
maintenance by providing the ideal service for
your vehicle.
Should the day come when you decide to sell
your BMW, a complete dealer service history
will prove to be an asset of inestimable value.
CBS Condition Based Service
Sensors and special algorithms take the differ-
ent driving conditions of your BMW into
account. Condition Based Service uses this to
determine the current and future service
requirements. By letting you define a service
and maintenance regimen that reflects your
own individual requirements, the system builds
the basis for trouble-free driving.
You can set the Control Display to show
remaining distances and times of selected
maintenance intervals and legally mandated
deadlines, refer to page75:
>Engine oil
>Brake pads, front and rear separately
>Brake fluid>Vehicle check
>Legally mandated inspections depending
on local regulations
Service data in remote control
Your vehicle stores the information required for
maintenance continuously in the remote con-
trol during driving. After accessing the data
stored in the remote control, your BMW Service
Advisor can suggest precisely the right array of
service procedures for your own individual vehi-
cle. You should therefore hand over the remote
control you last used to drive to the BMW Ser-
vice Advisor when you take your vehicle in for
service.
Make sure the date is set correctly, refer
to page82, otherwise the effectiveness
of CBS Condition Based Service is not
ensured.<

Giving and receiving assistance
Emergency request
Conditions for an emergency request:
>Full preparation package mobile phone.
With this equipment, an emergency request
is still possible when no mobile phone is
paired in the vehicle.
>BMW Assist is activated.
Activating BMW Assist, refer to page228.
>Radio readiness is switched on.
>The BMW Assist system is logged in on a
wireless communications network.
>The emergency request system is opera-
ble.
When the contract of participation with BMW
Assist expires, the BMW Assist system can be
deactivated by a BMW Sports Activity Vehicle
Center without having to visit a workshop. Once
the BMW Assist system has been deactivated,
emergency requests are not possible. The
BMW Assist system be reactivated by a BMW
Sports Activity Vehicle Center after signing a
new contract.
Initiating an emergency request
1.Briefly press protective cover to open.
Depending on the vehicle's equipment, the
arrangement of the switches and indicator
lamps may differ somewhat.
2.Press the SOS button for at least 2 sec-
onds.The LED in the button lights up. As soon as the
voice connection to the BMW Assist Response
Center has been established, the LED flashes.
When the emergency request is received at the
BMW Assist Response Center, the BMW Assist
Response Center contacts you and takes fur-
ther steps to help you. Even if you are unable to
answer, the BMW Assist Response Center can
take further steps to help you under certain
conditions.
If conditions allow, remain in the vehicle until
the connection has been established. You will
then be able to provide a detailed description of
the situation.
If the current position of your vehicle can be
determined, it will be forwarded to the BMW
Assist Response Center.
If the LED flashes, but you are unable to hear
the BMW Assist Response Center through the
hands-free system, this could indicate, for
instance, that the hands-free system is no
longer operational. However, you may then still
be audible for the BMW Assist Response Cen-
ter.
Under certain conditions, an emergency
request is automatically initiated immediately
after a severe accident. The automatic collision
notification is not affected by the button being
pressed.
For technical reasons, the emergency
request cannot be guaranteed under
unfavorable conditions.<
Warning triangle*
The warning triangle is located in the cargo bay.
