four wheel drive BMW Z4 2014 E89 Owner's Manual

wise, reliable signaling of a flat tire is not en‐
sured. Initialize the system after each correc‐
tion of the tire inflation pressure and after
every tire or wheel change.
System limits Sudden tire damage
Sudden serious tire damage caused by
external influences cannot be indicated in ad‐
vance.◀
A natural, even pressure loss in all four tires
cannot be detected.
The system could be delayed or malfunction in
the following situations:▷When the system has not been initialized.▷When driving on a snowy or slippery road
surface.▷Sporty driving style: slip in the drive
wheels, high lateral acceleration.▷When driving with snow chains.
Status display
The current status of the Flat Tire Monitor can
be displayed on the Control Display, e.g.,
whether or not the FTM is active.

The status is displayed.
Initialization
The initialization process adopts the set infla‐
tion tire pressures as reference values for the
detection of a flat tire. Initialization is started by
confirming the inflation pressures.
Do not initialize the system when driving with
snow chains.1."Vehicle Info"2."Vehicle status"3."Reset"4.Start the engine - do not drive away.5.Start the initialization with "Reset".6.Drive away.
The initialization is completed while driving,
which can be interrupted at any time.
The initialization automatically continues when
driving resumes.
Indication of a flat tire The warning lamps come on in yellow
and red. A message appears on the
Control Display. In addition, a signal
sounds.
There is a flat tire or a major loss in tire inflation
pressure.
1.Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.2.Check whether the vehicle is fitted with
regular tires or run-flat tires.Seite 93SafetyControls93

If the tire inflation pressure in all four tires
is correct, the Tire Pressure Monitor may
not have been reset. Reset the system.
Possible driving distance with complete loss of
tire inflation pressure:
The possible driving distance after a loss of tire
inflation pressure depends on the cargo load
and the driving style and conditions.
For a vehicle containing an average load, the
possible driving distance is approx.
50 miles/80 km.
When the vehicle is driven with a damaged tire,
its handling characteristics change, e.g., re‐
duced lane stability during braking, a longer
braking distance, and altered self-steering
properties. Adjust your driving style accord‐
ingly. Avoid abrupt steering maneuvers or driv‐
ing over obstacles, e. g., curbs, potholes, etc.
Because the possible driving distance de‐
pends on how the vehicle is used during the
trip, the actual distance may be smaller or
greater depending on the driving speed, road
conditions, external temperature, cargo load,
etc.
Continued driving with a flat tire
Drive moderately and do not exceed a
speed of 50 mph/80 km/h.
A loss of tire inflation pressure results in a
change in the handling characteristics, e.g., re‐
duced lane stability during braking, a longer
braking distance and altered self-steering
properties.◀
Final tire failure
Vibrations or loud noises while driving
can indicate the final failure of the tire. Reduce
speed and stop; otherwise, pieces of the tire
could come loose and cause an accident. Do
not continue driving, and contact your service
center.◀
Message when not reset
The warning light lights up yellow. A
Check Control message is displayed.
The system may not have been reset
although a wheel was changed.
Check the tire inflation pressure and reset the
system, refer to page 95.
System limits
The system does not function properly if it has
not been reset, e.g., it may identify a tire as flat
in spite of the fact that the tire is filled to the
correct inflation pressure.
The tire pressure depends on the temperature
of the tire. An increase in the tire temperature,
e.g., while driving or due to sunlight, increases
the tire inflation pressure. The tire pressure
decreases when the tire temperature drops. In
case of severe temperature drops, this behav‐ ior may lead to a warning on account of the de‐
fined warning limits.
Malfunction The small warning light flashes in yel‐
low and then lights up continuously;
the larger warning light comes on in
yellow. On the Control Display, the
tires are shown in gray and a message ap‐
pears. No flat tire can be detected.
Display in the following situations:▷A wheel without TPM electronics is fitted:
have the service center check it if neces‐
sary.▷Malfunction: have the system checked by
your service center.▷TPM could not be fully reset. Reset the
system again.

TelephoneVehicle equipmentThis 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.
When using the features and systems descri‐
bed here, adhere to local regulations.
At a glance The conceptMobile phones or other external devices such
as audio players can be connected to the vehi‐
cle via Bluetooth.
Bluetooth® is a registered trademark of Blue‐
tooth® SIG, Inc.
After these devices are paired once, they are
recognized automatically when the ignition is
switched on as soon as they are in the vehicle
and can then be operated via iDrive, the but‐
tons on the steering wheel, and via voice acti‐
vation.
Depending on their functionality, external devi‐
ces can be used via the vehicle as a telephone
or as an audio source. The telephone functions
are described in the following. Operating the
audio functions, refer to page 183.
Up to four external devices can be paired.
Certain functions may need to be enabled by
the mobile phone provider or service provider.
Using the mobile phone while driving
Make entries only when traffic and road
conditions allow. Do not hold the mobile phone
in your hand while you are driving; use the
hands-free system instead. If you do not ob‐serve this precaution, you can endanger the
vehicle occupants and other road users.◀
Snap-in adapter The snap-in adapter is used to:▷Hold the mobile phone.▷Recharge the battery.▷Connect the mobile phone to an outside
antenna of the vehicle.
This provides for better network reception
and consistent sound quality.

Displaying the vehicle identification
number and software part number
The vehicle identification number and software part number are needed to determine which
mobile phones are supported by the mobile
phone preparation package. The software ver‐
sion of the mobile phone may also be required.

Do not operate a mobile phone that is con‐
nected to the vehicle on the mobile phone key‐
pad, as this may lead to a malfunction.
