TeleService , BMW Assist
TeleService
TeleService supports you in communicating
with your BMW center. The installed car phone
can be used to transmit data on the service sta-
tus of your vehicle or on legally mandated
inspections directly to your BMW center. These
are the same data which are stored in the mas-
ter key for CBS Condition Based Service. Your
BMW center can then contact you, and you can
make an appointment that suits you while you
are still on the road. Your advantage is that your
BMW center can prepare in advance for the
required maintenance work. The TeleService
functions are country-specific and depend on
the contract: the data on the service status of
your vehicle or on legally mandated inspections
is transmitted on a country-specific basis either
automatically before they fall due or simulta-
neously when you call your BMW center. Your
BMW center will be glad to provide more
detailed information.
BMW Assist
With BMW Assist, other services are available
to you in addition TeleService, e.g. the your
vehicle's position data can be transmitted to the
BMW Assist response center when an emer-
gency call
* has been initiated.
Many functions of BMW Assist depend on the
individually agreed contract. The data transmis-
sion, e.g. of CBS Condition Based Service, is
different in individual countries.
The subscriber agreement must be completed
successfully before using the BMW Assist ser-
vices.
Requirements
The installed car phone is logged on to a porta-
ble telephone network. This network must be
capable of transmitting the services.To transmit position data, the vehicle must be
able to determine the current position. This is
displayed on the Control Display. In order to
enable and update TeleService or BMW Assist,
a GPS signal must be present.
Enabling TeleService or BMW Assist
For you to be able to use the services of
TeleService or BMW Assist, these must be
enabled.
Leave the ignition key in position 1 during the
entire operation.
Control Center, for principle details, refer to

Fuel specifications
The engine uses unleaded gasoline only.
Required fuel
Premium unleaded gasoline
The minimum octane rating is 91.
If you use gasoline with this minimum octane
rating, the engine may produce knocking
sounds when starting at high outside tempera-
tures. This has no effect on the engine life.
Minimum Octane Rating corresponds to the
Anti Knock Index AKI and is determined accord-
ing to the so-called (R+M)/2 method.
Do not use leaded gasoline, as otherwise
the lambda probe and catalytic converter
will be permanently damaged.<
Use high-quality brands
Field experience has indicated significant dif-
ferences in fuel quality: volatility, composition,
additives, etc., among gasolines offered for sale
in the United States and Canada. Fuels contain-
ing up to and including 10 % ethanol or other
oxygenates with up to 2.8 % oxygen by weight,
that is, 15 % MTBE or 3 % methanol plus an
equivalent amount of co-solvent, will not void
the applicable warranties with respect to
defects in materials or workmanship.
The use of poor-quality fuels may result in
drivability, starting and stalling problems,
especially under certain environmental condi-
tions such as high ambient temperature and
high altitude.
Should you encounter drivability problems
which you suspect could be related to the fuel
you are using, we recommend that you respond
by switching to a recognized high-quality
brand.
Failure to comply with these recommendations
may also result in unscheduled maintenance.<

heat when tested under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the
material of the tire to degenerate and reduce
tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to
a level of performance which all passenger car
tires must meet under the Federal Motor Vehi-
cle Safety Standard No. 109. Grades B and A
represent higher levels of performance on the
laboratory test wheel than the minimum
required by law.
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive speed,
underinflation, or excessive loading, either sep-
arately or in combination, can cause heat
buildup and possible tire failure.<
RSC – run-flat tires
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the side
of the tire, refer to page172.
M+S
Winter and all-season tires.
These have better winter properties than sum-
mer tires.
Tire condition
Inspect your tires frequently for tread wear,
signs of damage and foreign objects lodged in
the tread, and check the tread depth.
Minimum tread depth
The tread depth should not drop below 0.12 in/
3 mm, although, for example, European legisla-
tion only specifies a minimum tread depth of
0.063 in/1.6 mm.
At tread depths below 0.12 in/3 mm there is an
increased risk of high-speed hydroplaning,
even when only small amounts of water are
present on the road surface.
Winter tires noticeably loose their suitability for
winter use below a tread depth of 0.16 in/4 mm. New tires should be mounted in the interest of
safety.
Wear indicators at the tread-groove base, refer
to arrow, are distributed over the tire's circum-
ference and are marked on the side of the tire
with TWI – Tread Wear Indicator. If the indica-
tors are at the level of the profile, the legal per-
missible tread depth of 0.063 in/1.6 mm has
been reached.
Tire damage
Due to low-profile tires, please note that
wheels, tires and suspension parts are
more susceptible to road hazard and conse-
quential damages.
Unusual vibrations encountered during normal
vehicle operation can indicate tire failure or
some other vehicle defect. This can, for exam-
ple, be caused by driving over curbs. These
kinds of problems may also be signaled by other
changes in vehicle response, such as a strong
tendency to pull to the left or right.
In these cases reduce your speed immediately
and have the wheels and tires inspected imme-
diately. To do this, carefully drive to the next
BMW center or a specialized tire dealer which
works with personnel trained in accordance
with BMW specifications. Have the vehicle
towed to the workshop if necessary.
Tire damage can be extremely dangerous to
vehicle occupants and other road users.<
Unprofessional attempts by laymen to
service tires can lead to damage and acci-
dents. Have this work performed by skilled pro-
fessionals only. The technicians at your BMW
center will be glad to assist you with the
required professional knowledge and special-
ized equipment.<

Run-flat tires
If you switch from summer to winter tires, or
vice versa, use run-flat tires, refer to page172,
as in the event of a flat tire there is no spare tire
available. Your BMW center will be glad to
advise you.
Watch speed
Observe the permissible maximum speed
for the respective winter tires, as other-
wise tire damage and occur and cause acci-
dents.<
Storage
Always 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.
Snow chains*
BMW only tests certain fine-link snow chains,
classifies them as road-safe and approves
them. Consult your BMW center for more infor-
mation. BMW recommends using these
approved snow chains. These snow chains are
approved exclusively for use in pairs on the rear
wheels with the tire size:
>245/50 R 17 Y
>245/45 R 18 Y
Observe the chain manufacturer's instructions
when mounting snow chains. Do not exceed a
vehicle speed of 30 mph/50 km/h with the
chains mounted.
Do not initialize the Flat Tire Monitor after
mounting snow chains.
When you are driving with snow chains, it can
be beneficial to switch off DTC briefly, refer to
page82.<
