The individual vehicle
When you ordered your BMW, you chose vari-
ous items of equipment. This Owner's Manual
describes the entire array of options and equip-
ment available with a specific BMW model.
Please bear in mind that the manual may con-
tain information on accessories and equipment
that you have not specified for your own vehicle.
Sections describing options and special equip-
ment are marked by asterisks
* to assist you in
identifying possible differences between the
descriptions in this manual and your own vehi-
cle's equipment.
If equipment in your BMW is not described in
this Owner's Manual, please refer to the accom-
panying Supplementary Owner's Manuals.
Editorial notice
BMW pursues a policy of continuous, ongoing
development that is conceived to ensure that
our vehicles continue to embody the highest
quality and safety standards combined with
advanced, state-of-the-art technology. For this
reason, it is possible in exceptional cases that
features described in this Owner's Manual
could differ from those on your vehicle.
For your own safety
Maintenance and repair
Advanced technology, e.g. the use of
modern materials and powerful electron-
ics, requires specially adapted maintenance
and repair methods. You should therefore have
the corresponding work on your vehicle per-
formed only by your BMW center or at a work-
shop that works according to BMW repair pro-
cedures with correspondingly trained
personnel. If this work is not carried out prop-
erly, there is a danger of subsequent damage
and related safety hazards.<
Parts and accessories
For your own safety, use genuine parts
and accessories approved by BMW.
When you purchase accessories tested and
approved by BMW and Original BMW Parts, you
simultaneously acquire the assurance that they
have been thoroughly tested by BMW to ensure
optimum performance when installed on your
vehicle.
BMW warrants these parts to be free from
defects in material and workmanship.
BMW will not accept any liability for damage
resulting from installation of parts and accesso-
ries not approved by BMW.
BMW cannot test every product made by other
manufacturers to verify if it can be used on a
BMW safely and without risk to either the vehi-
cle, its operation, or its occupants.
Original BMW Parts, BMW Accessories and
other products approved by BMW, together
with professional advice on using these items,
are available from all BMW centers.
Installation and operation of non-BMW
approved accessories such as alarms, radios,
amplifiers, radar detectors, wheels, suspension
components, brake dust shields, telephones,
including operation of any mobile phone from
within the vehicle without using an externally
mounted antenna, or transceiver equipment, for
instance, CBs, walkie-talkies, ham radio or sim-
ilar accessories, may cause extensive damage

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.
Displays in the instrument cluster*
1Display for target speed
2HDC display
Malfunction
The HDC display disappears during HDC oper-
ation, or does not appear:
HDC is temporarily unavailable due to exces-
sive brake temperature, or DSC has failed.
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. Otherwise, the drive-off
assistant will no longer hold the car in place after approx. 2 seconds and the car will start to
roll backwards.<
Flat Tire Monitor FTM*
The concept
The Flat Tire Monitor detects pressure loss in a
tire by comparing the rotating speeds of the
individual tires while moving.
In the event of pressure loss, the rolling circum-
ference changes and, thus, the rotating speed
of the affected wheel. This change is detected
and is reported as a flat tire.
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must be initialized for the cor-
rect tire inflation pressure.
The system must be reinitialized each
time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed.<
System limitations
The Flat Tire Monitor is unable to warn
the driver of sudden, severe tire damage
caused by external factors, nor can it identify
the gradual loss of pressure that will inevitably
occur in all four tires over a lengthy period of
time.<
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, high lateral acceleration
>Snow chains are attached
Initializing the system
The initialization is completed during driv-
ing, which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically.
Do not initialize the system while snow chains
are attached.<

Technology for driving comfort and safety

1."Vehicle Info"
2."Vehicle status"
3."Reset"
4.Start the engine - do not drive away.
5.Start the initialization using "Reset".
6.Start to drive.
The initialization is completed during the trip.
"Status: Flat Tire Monitor active" is displayed
again on the Control Display.
Indication of a flat tire
The warning lamps come on in yellow
and red. A message appears on the
Control Display. In addition, an
acoustic signal sounds. There is a flat
tire or substantial loss of tire pressure.
1.Cautiously reduce speed to below 50 mph
or 80 km/h. Avoid sudden braking and
steering maneuvers. Do not exceed a speed
of 50 mph or 80 km/h.
If the car is not equipped with Run-
Flat Tires, refer to page204, the stan-
dard equipment by design, do not continue
driving. Otherwise a severe accident could
result if you continue driving.<
2.At the next opportunity, check the air pres-
sure in all four tires.
If all four tires are inflated to the cor-
rect pressures, the Flat Tire Monitor
might not have been initialized. The system
must then be initialized.<
3.In the event of complete tire pressure loss,
0 psi/0 kPa, you can estimate the possible distance for continued driving on the basis
of the following guidelines:
>With a light load:
1 to 2 persons without luggage:
approx. 155 miles/250 km
>With a medium load:
2 persons, cargo bay full, or 4 persons
without luggage:
approx. 90 miles/150 km
>With a full load:
4 persons, cargo bay full:
approx. 30 miles/50 km
Drive cautiously and do not exceed a
speed of 50 mph or 80 km/h, otherwise
there is a risk of an accident. In the event of
pressure loss, vehicle handling changes. This
includes reduced tracking stability in braking,
extended braking distance and altered natural
steering characteristics.
If unusual vibration or loud noises occur during
the journey, this may be an indication that the
damaged tire has finally failed. Reduce your
speed and pull over as soon as possible at a
suitable location. Otherwise parts of the tire
could come loose, resulting in an accident. Do
not continue driving. Instead, contact your
BMW center.<
Malfunction
The warning lamps come on in yel-
low. A message appears on the Con-
trol Display. The Flat Tire Monitor has
a malfunction or has failed. Have the
system checked as soon as possible.
Tire Pressure Monitor TPM*
The concept
TPM checks the inflation pressures of the four
mounted tires. The system notifies you if there
is a significant loss of pressure in one or more
tires.
