Vehicle equipment
In this chapter, all production, country, and
optional equipment that is offered in the model
range is described. As a result, some equip-
ment described may not be
available in a partic-
ular vehicle, for example due to the options or
national-market version selected. This also
applies to safety related functions and systems.
Sitting safely
The ideal sitting position can make a vital
contribution to relaxed, fatigue-free driving. In
conjunction with the sa fety belts, the head
restraints and the airbags, the seated position
has a major influence on your safety in the event
of an accident. To ensu re that the safety sys-
tems operate with optimal efficiency, we
strongly urge you to observe the instructions
contained in the following section.
For additional information on transporting
children safely, refer to page 58.
Airbags
Always maintain an adequate distance
between yourself and the airbags. Always
grip the steering wheel on the rim, with your
hands in the 3 o'clock and 9 o'clock positions,
to minimize the risk of injury to the hands or
arms in the event of the airbag being triggered
off.
No one and nothing should come between the
airbags and the seat occupant.
Do not use the cover of the front airbag on the
front passenger side as a storage area. Make
sure that the front passeng er is sitting correctly,
i.e. not resting feet or legs on the dashboard;
otherwise, leg injuries ca n occur if the front air-
bag deploys.
Make sure that passen gers keep their heads
away from the side airbag and do not lean against the cover of the
head airbag; otherwise,
serious injuries can result if the airbag
deploys. <
Even if you follow all the instructions, injuries
resulting from contact with airbags cannot be
fully excluded, depending on the circum-
stances. The ignition and inflation noise may
provoke a mild hearing loss in extremely
sensitive individuals. This effect is usually only
temporary.
For airbag locations and additional information
on airbags, refer to page 97.
Head restraint
A correctly adjusted head restraint reduces the
risk of neck injury in the event of an accident.
Adjust the head restraint in such a way
that its center is at approx. ear level.
Otherwise, there is an incr eased risk of injury in
the event of an accident. <
Head restraints, refer to page 52.
Safety belt
Before every drive, make sure that all occupants
wear their safety belts. Airbags complement the
safety belt as an additi onal safety device, but
they do not represent a substitute.
Your vehicle has four se ats, each of which is
equipped with a safety belt.
Never allow more than one person to
wear a single safety belt. Never allow
infants or small children to ride in a passenger's
lap. Make sure that the be lt in the lap area sits
low across the hips and does not press against
the abdomen.
The safety belt must not rest against the throat,
run across sharp edges, pass over hard or frag-
ile objects or be pinched. Fasten the safety belt
so that it sits as snugly as possible against the
lap and shoulder without being twisted. Other-
wise, the belt could slide over your hips and

Flat Tire Monitor FTM
The concept
The system does not measure the actual infla-
tion pressure in the tires.
The system detects a pressure loss in a tire by
comparing the rotational
speeds of the individ-
ual wheels while moving.
In the event of a pressure loss, the diameter and
therefore the rotational speed of the corre-
sponding wheel change. This is detected and
reported as a flat tire.
Functional requirement
The system must have be en initialized while the
tire inflation pressure was correct; otherwise,
reliable signaling of a flat tire is not ensured.
Each time a tire inflation pressure has been
corrected or a wheel or tire has been changed,
reinitialize the system.
System limitations
Sudden serious tire damage caused by
external influences ca nnot be indicated in
advance.<
The system will not detect a natural, uniform
pressure loss in all four tires. Therefore, check
the tire inflation pressure regularly.
In the following situations, the system could be
delayed or malfunction:
> System has not been initialized
> Driving on snowy or slippery road surface
> Performance-oriented style of driving: slip
in the drive wheels, hi gh lateral acceleration
> Snow chains are attached
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.
1."Vehicle Info"
2. "Vehicle status" 3.
"Flat Tire Monitor"
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 by selecting "Reset".
6. Start driving.
The initialization is completed during driv-
ing, which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically. <

ControlsTechnology for driving comfort and safety
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 pressure.
1. Reduce speed and stop the vehicle with
caution. Avoid sudden braking and steering
maneuvers.
If the vehicle is not equipped with run-flat
tires, do not continue driving; continuing
to drive can result in serious accidents. <
When a flat tire is reported, the Dynamic Stabil-
ity Control DSC is activated.
Actions in the event of a flat tire
Run-flat tires
With a damaged tire, is possible to continue
driving at speeds of up to 50 mph/80 km/h.
When driving with a damaged tire:
1. Avoid sudden braking and steering
maneuvers.
2. Do not exceed a speed of 50 mph/80 km/h.
3. At the next opportunity, check the inflation
pressure in all four tires.
If the inflation pressure in all four tires is cor-
rect, the Flat Tire Monitor might not have
been initialized. The sy stem must then be
initialized.
Possible driving distance with complete loss of
tire pressure:
The distance it is possible to drive with a flat tire
depends on the load and the stress on the
vehicle while driving.
With an average load, it may be possible to drive
for approx. 50 miles/80 km.
When driving with damaged tires, the handling
characteristics ch ange, e.g. the vehicle will skid
sooner when braking, braking distances will be
longer, or self-steerin g response will change. Adapt your driving style accordingly. Avoid
turning abruptly and driving over obstacles
such as curbs, potholes, etc.
Since the possible driving distance depends to
a considerable degree on
the strain exerted on
the vehicle while driving, it can be shorter or,
with a gentle driving style, can also be longer,
depending on the speed, road condition, out-
side temperature, vehicle load, etc.
Drive cautiously an d do not exceed a
speed of 50 mph/80 km/h.
When there is a tire pressure loss, the handling
characteristics change , e.g. there will be
reduced directional stability during braking,
braking distances will be longer, and self-
steering response will change. <
Vibrations or loud noises while driving can
indicate final failure of the tire. Reduce
your speed and bring the vehicle to a stop; oth-
erwise, tire components may become
detached, which could result in an accident. Do
not continue driving; instead, contact your
BMW center. <
Tire Pressure Monitor TPM
The concept
Check the inflation pressure in the four installed
tires. The system notifies you if there is a signif-
icant loss of pressure in one or more tires.
Functional requirement
The system must have been reset while the
inflation pressure was correct; otherwise, reli-
able signaling of a flat tire is not ensured.
Always use wheels with TPM electronics to
ensure that the system will operate properly.
Each time a tire inflation pressure has been
corrected or a wheel or tire has been changed,
reset the system.

5.Reset the inflation pr essure by selecting
"Reset".
6. Start driving.
The tires are shown in gray and "Resetting
TPM..." is displayed.
After driving a few minutes, the set inflation
pressures in the tires are accepted as the target
values to be monitored. The resetting process
is completed automatically as you drive. On the
Control Display, the wheels are shown in green
and "Status: TPM active" is displayed.
The trip can be interrupted at any time. When
driving resumes, resetting continues automati-
cally.
If a flat tire is detect ed while the system is
resetting, all tires on the Control Display
are displayed in yello w. The message "Low
tire!" is displayed.<
Message for low tire inflation pressure
The warning lamps light up in yellow
and red. A message appears on the
Control Display. In addition, a signal
sounds.
> There is a flat tire or substantial loss of tire
pressure in the indicated wheel.
> The system was not reset after a wheel
change and thus issues a warning based on
the inflation pressure s initialized last.
Reduce speed and stop the vehicle with
caution. Avoid sudden braking and steering
maneuvers. If the vehicle is not equipped with run-flat
tires, do not continue driving; continuing
to drive can result in serious accidents. <
When a low tire pressure is reported, the
Dynamic Stability Control DSC is activated.
Actions in the event of a flat tire
Run-flat tires
You can continue driving with a damaged tire at
speeds up to 50 mph/80 km/h.
When driving with a damaged tire: 1.
Avoid sudden braking and steering
maneuvers.
2. Do not exceed a speed of 50 mph/80 km/h.
3. At the next opportunity, check the inflation
pressure in all four tires.
If the inflation pressure is correct in all four
tires, then the Tire Pressure Monitor may
not have been reset. The system must then
be reset.

Overview
The concept
Mobile phones or other external devices, e.g.
audio players, can be connected to the vehicle
via Bluetooth.
Bluetooth® is a registered trademark of
Bluetooth® SIG, Inc.
After being paired once, when the ignition is
switched on, these devices are automatically
detected as soon as they are present in the
vehicle and can be controlled via iDrive, by the
buttons on the steering wheel, and by voice.
Depending on whether they are functioning as a
telephone and/or as an audio source, external
devices can be used via the vehicle. The tele-
phone functions will be described below. Oper-
ation of audio functions, refer to page 180.
Up to four external devices can be paired.
It may be necessary for some functions to be
activated by the mobile phone provider or
service provider.
Only make entries when traffic conditions
permit. Do not hold the mobile phone in
your hand while you are driving; use the hands-
free system instead. Otherwise, you may
endanger vehicle occupants and other road
users. <
Snap-in adapter
The snap-in adapter makes it possible:
>Accommodate the mobile phone.
> Recharge its battery.
> Connect it to an external antenna of the
vehicle.
This assures a better network connection
and constant sound quality.
