Indicator and warning lamps
The concept
Control and warning lamps can light up in vari-
ous combinations and colors.
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 on Info Display explain the
meaning of the indicator and warning lamps
shown.
You can view additional information, e.g.
regarding the cause of a malfunction and the
corresponding action to take, in the Check Con-
trol, refer to page80.In urgent cases, this information will be shown
as soon as the corresponding lamp comes on.

Tilt alarm sensor
The tilt of the vehicle is monitored. The alarm
system reacts, e.g. in case of an attempted
wheel theft or towing.
Interior motion sensor
In order for the interior motion sensor to func-
tion properly, the windows and glass sunroof
must be completely closed.
Avoiding unintentional alarms
The tilt alarm sensor and interior motion sensor
may be switched off at the same time. This pre-
vents unintentional alarms, e.g. in the following
situations:
>In duplex garages
>During transport on car-carrying trains,
boats/ships or on a trailer
>When animals are to remain in the vehicle
Switching off tilt alarm sensor and
interior motion sensor
Press the button on the remote control
again as soon as the vehicle is locked.
The indicator lamp lights up briefly and then
flashes continuously. The tilt alarm sensor and
the interior motion sensor are switched off until
the next time the vehicle is unlocked and subse-
quently locked again.
Comfort Access*
With Comfort Access, you can have access to
your vehicle without having to hold the remote
control in your hand. It is sufficient to carry the
remote control on your person, e.g. in a jacket
pocket. The vehicle automatically detects the
associated remote control inside the vehicle or
in its immediate vicinity.
Comfort Access supports the following func-
tions:
>Locking/unlocking the vehicle
>Unlocking the luggage compartment lid
separately
>Starting the engine
Functional requirements
>The vehicle can only be locked if the remote
control is outside the vehicle.
>The next unlocking and locking cycle is not
possible until after approx. 2 seconds.
>The engine can only be started if the remote
control is inside the vehicle.
Comparison to conventional remote
control
You can control the functions mentioned previ-
ously with the Comfort Access or by pressing
the buttons on the remote control. Therefore
please first familiarize yourself with the instruc-
tions for opening and closing, starting on
page32.
The specific features involved in the use of
Comfort Access are described below.
If a short delay occurs when opening or
closing the windows and the glass sun-
roof, then this indicates that the system is
checking whether a remote control is located in
the vehicle. Please repeat opening or closing if
necessary.<
Unlocking
Pull a door handle. This corresponds to press-
ing the button.
Only the door of the door handle you have
pulled is unlocked.

PDC Park Distance Control*
The concept
The PDC assists you when you are parking.
Audible signals and an optical display indicate
that you are approaching an object in front of or
behind your vehicle. To measure the distance,
four ultrasonic sensors are provided in each
bumper. The range of these sensors is approx.
6 ft/2 m. However, an acoustic warning begins
to sound for the sensors at the front and at the
two rear corners at approx. 24 in/60 cm, and for
the center rear sensors at approx. 5 ft/1.50 m.
PDC is a parking aid that can indicate
objects when they are approached
slowly, as is usually the case when parking.
Avoid approaching an object at high speed; oth-
erwise, the system may sound the warning of
physical obstacles too late.<
Automatically activating
The system is activated approx. 1 second after
you engage the transmission position R with
the engine running or the ignition switched on.
Wait this short period before proceeding.
Manual activation
Press the button, the LED lights up.
Manual deactivation
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 switches
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 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 Info Display. PDC has failed.
Have the system checked.
To prevent this problem, keep the sensors
clean and free of ice or snow in order to ensure
that they will continue to operate effectively.
When using high-pressure washers, do not
spray sensors for long periods and keep the
sprayer at least 4 in/10 cm away from the sen-
sors.
PDC with visual warning
You can also have the system show distances
to objects on the Control Display. Objects that
are farther away are displayed there before a
signal tone begins to sound.
iDrive, for principle details, refer to page16.

Deactivating DTC
Select "DTC" and press the controller.
The LED on the Control Display and the DTC
indicator lamp on the Info Display go out.
Dynamic Drive
The concept
Dynamic Drive minimizes body roll and opti-
mizes vehicle stability during cornering and
evasive maneuvers.
Active stabilizers at the front and rear axles form
the basis for Dynamic Drive. Suspension com-
pliance adapts to suit driving conditions, vary-
ing from performance-oriented during corner-
ing to smooth and comfort-oriented when the
vehicle is traveling in a straight line. During vehi-
cle 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 appears on the Info Display.
A malfunction has occurred in the
Dynamic Drive system. Have the system
checked as soon as possible.
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 Check Control message indicates an oil loss,
stop as soon as possible at a suitable location
and switch off the engine. Do not continue driv-
ing, contact your BMW center.
Self-leveling suspension*
Malfunction
The warning lamp for self-leveling sus-
pension lights up yellow and a message
appears on the Info Display.
A malfunction has occurred in the level control
system.
Stop driving and check the vehicle:
>The vehicle is considerably lower at the rear
than at the front, possibly also on one side,
at the rear left compared to the rear right.
>The ground clearance is reduced or the
driving comfort is noticeably reduced.
>The position of the vehicle is normal, but a
malfunction is indicated.
Drive to the nearest BMW center or a workshop
that works in accordance with BMW guidelines
and uses appropriately trained personnel. Drive
with appropriate caution in the meantime.
EDC Electronic Damping
Control*
If the influencing variables such as road surface
quality or operating conditions such as steer-
ing, braking etc. change, the damping automat-
ically adjusts to the new conditions.
iDrive, for principle details, refer to page16.
1.Press the button to open the start
menu.
2.Move the controller toward "Settings".
3.Select "Vehicle" and press the controller.

Socket for OBD Onboard
Diagnostics
Components which are decisive for the
exhaust-gas composition can be checked via
the OBD socket with a device.
This socket is located to the left on the driver's
side, on the underside of the instrument panel
under a cover.
Emissions values
The warning lamp lights up. The emis-
sions values are deteriorating. Have the
vehicle checked as soon as possible.
Display of the previously described
malfunction on Canadian models.
Under certain circumstances, the warning lamp
will flash. This is a sign of excessive misfiring of
the engine. In this case you should reduce
speed and drive to the nearest BMW center as
soon as possible. Serious engine misfiring,
even for only a short period of time, can seri-
ously damage emission control components,
especially the catalytic converter.
If the fuel filler cap is not properly tight-
ened, the OBD system can detect the
vapor leak and the indicator lamp will light up. If
the cap is then tightened, the display should go
out within a few days.<
Event Data Recorders
Your vehicle may be equipped with one or sev-
eral measuring and diagnosis modules, or with a
device for recording or transmitting certain
vehicle data or information. If you have also
signed a contract of participation for BMW
Assist, certain vehicle data can be transmitted
or recorded to enable corresponding services.
Care
You can find useful information on caring for
your BMW in the Caring for your vehicle bro-
chure.

ensure that they are tightened to the speci-
fied torque. The tightening torque is
100lbft/140Nm.<
2.Reverse the removal sequence when stor-
ing the wheel and tools in the vehicle.3.Check and correct the tire inflation pressure
at the earliest opportunity.
Use valve stem seal caps to protect
valve stems from dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.<

Towing and tow starting
Observe applicable laws and regulations
for tow starting and towing.<
Do not transport any passengers other
than the driver in a vehicle that is being
towed.<
Using tow fitting
The threaded tow fitting is stored in the
onboard tool kit and must always remain in the
vehicle. It can be screwed in at the front or rear
of the BMW.
Only use the tow fitting that comes with
the vehicle and screw it in as far as it will
go. Use the tow fitting for towing only on roads.
Avoid lateral loading of the tow fitting, e.g. do not lift the vehicle by the tow fitting. Otherwise,
damage to the tow fitting and the vehicle can
occur.<
Access to screw thread
Press the arrow symbol to push out the cover.
Being towed
Do not tow the vehicle by the rear axle;
because there is no steering lock, the
wheels could turn to an extreme angle during
towing. There is no power assist with the
engine stopped. This then requires increased
effort for braking and steering.<
Switch on the hazard warning flashers depend-
ing on the local regulations. If the electrical sys-
tem fails, mark the vehicle to be towed, e.g. with
a sign or warning triangle in the rear window.
Selector lever in position N. Releasing
shiftlock manually, refer to page64. To
avoid damaging the automatic transmission, do
not exceed a towing speed of 45 mph/70 km/h
and a towing distance of 95 miles/150 km.<
Towing methods
In some countries, towing with tow bars or
ropes in public traffic is not permitted.
Familiarize yourself with the regulations on tow-
ing in the respective country.
With tow bar
The towing vehicle must not be lighter
than the vehicle to be towed; otherwise,
it will no longer be possible to control vehicle
response.<
