Vehicle equipment
In this chapter, all pr oduction, 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 con-
tribution to relaxed, fatigue-free driving. In con-
junction with the safety belts, the head
restraints and the airbags, the seated position
has a major influence on your safety in the event
of an accident. To ensure 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 chil-
dren safely, refer to page 53.
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 shou ld 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,
e.g. not resting feet or legs on the dashboard;
otherwise, leg injuries ca n occur if the front air-
bag deploys.
Make sure that passengers 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 sensi-
tive individuals. This e ffect is usually only tem-
porary.
For airbag locations and additional information
on airbags, refer to page 99.
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. Oth-
erwise, there is an increase d risk of injury in the
event of an accident. <
Head restraints, refer to page 45.
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 repres ent a substitute.
Your vehicle has four seats, 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

xDrive
xDrive is your BMW's four-wheel-drive system.
The combined efforts of xDrive and DSC help to
further optimize traction and driving dynamics.
The xDrive four-wheel-drive system distributes
driving power variably to the front and rear axles
depending on the drivin g situation and road
conditions.
Hill Descent Control HDC
HDC is a downhill driving assistant that controls
your speed on steep downhill gradients and
makes it even easier to control your BMW's
handling under these conditions. The vehicle
then moves slightly faster than double walking
speed without the driver needing to intervene.
HDC can be activated as long as you are driving
under approx. 20 mph or 35 km/h. When driving
downhill at a speed of under approx. 20 mph or
35 km/h, the vehicle's speed is automatically
reduced to slightly more than double walking
speed and maintained.
Increasing or de creasing speed
By accelerating or braking you can change this
speed within a range from approx. 3 to 15 mph,
approx. 5 to 25 km/h.
You can specify a target speed within the same
range by using the lever of the cruise control.

2 To decrease speed
Activating HDC
Press the button; the LED lights up.
When the vehicle is being braked automatically,
the LED flashes.
Deactivating HDC
Press the button again; the LED goes out.
HDC is automatically deactivated at speeds
greater than approx. 35 mph/60 km/h.
Using HDC
In cars with manual transmission:
Use HDC in lower gears and in reverse gear.
With automatic transmission:
You can use HDC in any drive position.

Controls
Drive-off assistant
The drive-off assistant enables you to drive off
smoothly on uphill gradients. It is not necessary
to use the parking brake for this.
1.
Hold the car in place by depressing the
brake.
2. Release the brake and drive off without
delay.
The drive-off assistant holds the car in
place for approx. 2 seconds after the
brake is released. Drive off without delay after
releasing the brake. Ot herwise, the drive-off
assistant will no longer hold the car in place
after approx. 2 seconds an d the car will start to
roll backwards. <
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 cor-
rected 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.<
A natural, steady pressure loss in all four tires is
not detected. 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
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.
For operating principle refer to page 82.
1. Start the engine imme diately before pulling
away, but do not drive off yet.
2. Briefly press the button 1 in the turn signal/
high beam lever up or down repeatedly until
the corresponding symbol and "RESET"
appear.
3. Press button 2 to confirm your choice of the
Flat Tire Monitor.

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 co rrect; 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 cor-
rected or a wheel or tire has been changed,
reset the system.
System limitations
Sudden serious tire damage caused by
external influences ca nnot be indicated in
advance.<
The system does not function correctly if it has
not been reset. For example, a flat tire may be
indicated even though the tire inflation pres-
sures are correct.
The system is inactive and cannot indicate a flat
tire:
> When a wheel without TPM electronics is
installed.
> Interference with TPM by other systems or
devices with the same transmission fre-
quency.
Resetting the system
Each time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed,
reset the system.
For operating principle refer to page 82.
1. Start the engine, but do not start driving.
2. Briefly press the button 1 in the turn signal/
high beam lever up or down repeatedly until the corresponding symbol and "RESET"
appear.
3. Press button 2 to confirm your choice of the
Tire Pressure Monitor. The following dis-
play appears:
4. Press button 2 for approx. 5 seconds, until
the small warning lamp lights up in yellow
and the following appears in the display:
5. Start driving.
After several minutes of driving time, the
adjusted inflation pressures will be adopted as
nominal values. The resetting process is com-
pleted automatically as you drive. The indicator
lamp goes out after the system reset is com-
pleted.

ControlsTechnology for driving comfort and safety
The trip can be interrupted at any time. When
driving resumes, resetting continues automati-
cally.
Message for low tire inflation pressure
The warning lamps light up in yellow
and red. 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 cau-
tion. 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 maneu-
vers.
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.
Possible driving distance with complete loss of
tire inflation pressure:
The distance it is possible to drive with a flat tire
depends on the load and the stress on the vehi-
cle 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-steer-
ing response will change. <
Vibrations or loud noises while driving can
indicate complete fa ilure of the tire.
Reduce your speed and bring the vehicle to a
stop; otherwise, tire components may become
detached, which could result in an accident. Do
not continue driving; instead, contact your
BMW center. <
Malfunction
The small warning lamp flashes in
yellow and then lights up continu-
ously; the large warning lamp lights
up in yellow. No punctures can be
detected.
Display in the follo wing situations:
> A wheel without TPM electronics has been
installed:
Have it checked by your BMW center.
> Malfunction
Have the system checked.
> Tire Pressure Monitor was unable to com-
plete the resetting process. Reset the sys-
tem again.
