Indicator and warning lamps
The concept
Indicator and warning lamps can light up in dif-
ferent combinations and colors, both in the dis-
play area1 and in the display2
When the engine is started or the ignition is
switched on, some lamps are checked for
proper operation and light up briefly in the pro-
cess.
Explanatory text messages
Text messages at the bottom edge of the Con-
trol Display explain the meaning of the indicator
and warning lamps displayed.
You can consult Check Control for additional
information, e.g. regarding the cause of a mal-function or the appropriate actions to take, refer
to page79.
In cases of corresponding urgency, this infor-
mation is immediately displayed when the
associated lamps light up.
Indicator lamps without text messages
The following indicator lamps in the display
area1 indicate that certain functions are active:
Handbrake set60
Handbrake for Canadian models
Front fog lamps98
DTC Dynamic Traction Control87
High beams/headlamp flasher97
Lamp flashes:
DSC or DTC is controlling the drive
and braking forces to maintain vehicle
stability87

To request the date:
Press the CHECK button on the turn signal
lever, refer to page79.
To set time and date, refer to page82.
You can set the unit of measure 7 or 6 on the
Control Display, refer to Units of measure on
page83.
Outside temperature warning
If the display drops to +377/+36, a signal
sounds and a message appears. There is an
increased danger of ice.
Ice can form even at temperatures above
+377/+36. Drive carefully, especially
on bridges and shaded roadways; otherwise,
your risk of accident increases.<
Tachometer
The white-striped advance warning field,
arrow1, changes depending on the engine
temperature. The segments disappear in
sequence as the engine warms to its normal
operating temperature.
Avoid allowing the engine speed to rise as far as
the advance warning field whenever possible.
It is absolutely crucial to avoid engine speeds in
the red warning field, arrow2.
In this range, the fuel supply is interrupted to
protect the engine.
Coolant temperature
Should the coolant and therefore the engine
become too hot, a warning lamp lights up. In
addition, a message appears on the Control
Display.
Checking coolant level, refer to page193.

PDC Park Distance Control*
The concept
The PDC assists you when you are parking.
Acoustic signals and an optical display
* alert
you to the approach of an object from behind
your vehicle. To measure the distance, there
are four ultrasonic sensors in each bumper.
The range of these sensors is approx. 7 ft/2 m.
But an acoustic warning first sounds at approx.
24 in/60 cm for the sensors at the front and two
rear corners and at approx. 5 ft/1,50 m for the
center rear sensors.
PDC is a parking aid that can indicate the
presence of objects when they are being
approached slowly, as is usually the case when
parking. Avoid approaching an object at high
speed; otherwise, the physical circumstances
could cause the system warning to be activated
too late.<
Automatically activating
With the engine running or the ignition switched
on, the system starts to operate automatically
approx. 1 second after you shift into reverse.
Wait this short period before driving.
Switching on manually
Press the button; the LED lights up.
Switching off manually
Press the button again; the LED goes out.
After driving approx. 165 ft/50 m or at over
approx. 20 mph/30 km/h, the system is
switched off and the LED goes out. You can
reactivate the system manually as needed.
Signal tones
An intermittent signal indicates the distance of
the vehicle from an object being approached.
Thus, an object detected to the left rear of the
vehicle will be indicated by a signal tone from
the left rear speaker, etc. As the distance
between vehicle and object decreases, the
intervals between the tones become shorter.
The signal tone becomes continuous once the
distance to the nearest object falls to below
roughly 1 ft/30 cm.
An intermittent tone is interrupted after approx.
3seconds:
>if you remain in front of an object that was
only detected by one of the corner sensors
>if you drive parallel to a wall
Malfunction
The LED in the button flashes and a message
appears on the Control Display. PDC is mal-
functioning. Have the system checked.
As a preventive measure, keep the sensors
clean and free of ice or snow in order to ensure
that they will continue to operate effectively. Do
not spray the sensors with high-pressure wash-
ers for prolonged intervals and always keep the
nozzle at least 4 in/10 cm from the sensors.
PDC with visual warning*
You can also enjoy the option of having the sys-
tem show the approach to an object on the
Control Display. Objects that are farther away
are already shown there before a signal tone
sounds.

Dynamic Drive*
The concept
Dynamic Drive minimizes body roll and opti-
mizes vehicle stability during cornering and
evasive maneuvers.
Dynamic Drive is based on active stabilizers on
the front and rear axles. Suspension compli-
ance adapts to suit driving conditions, varying
from performance-oriented during cornering to
smooth and comfort-oriented when the vehicle
is proceeding in a straight line. During vehicle
operation, the system continuously runs
through closed-loop control cycles lasting only
fractions of a second.
The system assumes operational status each
time you start the engine.
Malfunction
The warning lamp lights up yellow and
a message is shown on the Control Dis-
play. There is a malfunction in the sys-
tem. Have the system checked as soon as pos-
sible.
If a malfunction occurs, please remember
to adapt your speed accordingly, espe-
cially in curves.
The suspension will be noticeably softer and
the vehicle will display a greater tendency to tilt
during cornering and in crosswinds.
If a message stating that you should stop is
shown on the Control Display, stop at a suitable
location and switch off the engine as soon as
possible. In this case the oil level in the reservoir
may have dropped below the minimum, possi-
bly owing to a leak in the hydraulic system. Do
not continue driving, but instead contact your
BMW center.<
Flat Tire Monitor FTM
The concept
The Flat Tire Monitor keeps track of the infla-
tion pressures in the tires as you drive. The sys-
tem provides an alert whenever the inflation
pressure drops significantly in relation to the
pressure in another tire.
In the event of a pressure loss, the rolling radius
and therefore the rotation speed of the wheels
change. This change is detected and signaled
as a flat tire.
Functional requirement
To ensure the reliable signaling of a flat tire, the
system must be initialized at the correct tire
inflation pressure.
The initialization must be repeated after
every correction of the tire inflation pres-
sure and after every tire or wheel change.<
System limits
The Flat Tire Monitor cannot indicate
sudden severe tire damage caused by
outside factors and does not detect a natural,
even pressure drop in all four tires.<
In the following situations, the system could be
delayed or malfunction:
>System has not been initialized
>Driving on snow-covered or slippery roads
>Sporty driving style: slip in the drive wheels,
high lateral acceleration
>Driving with snow chains
*
Initializing system
The initialization finishes during driving,
which can be interrupted at any time.
When driving resumes, the initialization is auto-
matically continued.
Do not initialize the system when driving with
snow chains
*.<
iDrive, for principle details, refer to page16.

3.Select "Vehicle settings" and press the
controller.
4.Select "FTM" and press the controller.
5.Start engine, but do not start driving.
6.Select "Set tire pressure" and press the
controller.
7.Select "Yes" and press the controller.
8.Start driving.
The message "Initializing..." is displayed.
The initialization is completed during driving.
Then the message "Status: FTM active"
appears on the Control Display again.
Indication of a flat tire
The warning lamp lights up in red. A
message appears on the Control Dis-
play. In addition, an acoustic signal
sounds. There is a flat tire or extensive inflation
pressure loss.
1.Cautiously reduce the vehicle speed to
below 50 mph/80 km/h. Avoid sudden brak-
ing and steering maneuvers. Do not exceed
a vehicle speed of 50 mph/80 km/h.Stop driving if the vehicle is no longer
equipped with run-flat tires, as it was
when it came from the factory, refer to
page188. Continued driving after a flat tire
can result in serious accidents.<
2.Check the air pressure in all four tires at the
next opportunity.
If the tire inflation pressure in all four
tires is correct, the Flat Tire Monitor
may 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 run-flat
tires, based on the following guide values:
>With low load:
1 to 2 persons without luggage:
approx. 155 miles/250 km.
>With medium load:
2 persons, luggage compartment full, or
4 persons without luggage:
approx. 94 miles/150 km.
>With full load:
4 persons, luggage compartment full:
approx. 30 miles/50 km.
Drive reservedly and do not exceed
a speed of 50 mph/80 km/h. In the
event of pressure loss, vehicle handling
changes. This includes reduced tracking
stability in braking, extended braking dis-
tances and altered natural steering charac-
teristics.
If unusual vibrations or loud noises occur
while the vehicle is being driven, this can
indicate final failure of the damaged tire.
Reduce speed and stop at a suitable loca-
tion as soon as possible; otherwise, pieces
of the tire could become detached and
cause an accident. Do not continue driving,
but instead contact your BMW center.<

No changes of any nature may be made to the
individual components of the rollover protec-
tion system and wiring.
Work on the rollover protection system may
only be performed at a BMW center.
Unprofessional attempts to service the system
can lead to failure or malfunction.For a system check and to ensure long-term
functioning, you must comply with the mainte-
nance intervals of the service requirements,
refer to page77.<
Head-Up Display*
The concept
With the Head-Up Display, important informa-
tion is projected into the driver's field of view,
e.g. navigation instructions. This enables you to
absorb this information without looking away
from the road.
Switching on/off
With the engine running or the ignition switched
on:
Press the button to activate or deactivate this
system.

cannot detect fog. To avoid safety risks, you
should always switch on the lamps manually
under these conditions.<
Adaptive Head Light*
The concept
Adaptive Head Light is a variable headlamp
control system that enables better illumination
of the road surface. Depending on the steering
angle and other parameters, the light from the
headlamp follows the course of the road.
Activating Adaptive Head Light
In switch position1, the Adaptive Head Light is
active and the automatic headlamp control is
switched on.
To avoid blinding oncoming traffic, the Adaptive
Head Light is not active when driving in reverse
and points toward the passenger side when the
vehicle is stopped.
Malfunction
The LED next to the symbol for automatic head-
lamp control flashes. The Adaptive Head Light
is malfunctioning or has failed. Have the system
checked as soon as possible.
High beams/
roadside parking lamps

Roadside parking lamps, left or right*
You also enjoy the option of lighting up just one
side of your vehicle when parking. When using
this function, comply with national regulations:
After parking the vehicle, press the lever in the
desired direction3, past the resistance point.
The roadside parking lamps drain the bat-
tery. Avoid using for longer periods; oth-
erwise, it may not be possible to start the
engine.<
High-beam assistant*
The concept
This system automatically switches the high
beams on and off again. A sensor on the front of
the interior rearview mirror controls the pro-
cess. The assistant ensures that the high
beams are switched on whenever the traffic sit-
uation allows. This reduces the strain on you
while at the same time providing you with the
best possible visibility. Of course, you can inter-
vene at any time and switch the high beams on
and off in the accustomed manner.
Activating high-beam assistant
1.Turn the light switch to switch position1,
refer to page96.
2.Press the turn signal lever in the high beam
direction with the low beams switched on.
The indicator lamp in the instrument
cluster lights up when the high-beam
assistant is activated. The assistant
automatically switches between high and low
beams, reacting to oncoming traffic and traffic
