Indicator and warning lamps
The concept
The indicator and warning lamps can light up in
different combinations and colors.
Some lamps are tested for proper function by
briefly lighting up during starting of the engine
or when the ignition is switched on.
Explanatory text messages
Text messages at the bottom edge of the Con-
trol Display explain the meaning of the dis-
played indicator and warning lamps.
Additional information, e.g. on the cause of a
malfunction and on the corresponding need to
take action can be displayed via the Check Con-
trol, refer to page78.In the case of corresponding urgency, this infor-
mation is displayed immediately when the
related lamp lights up.
Indicator lamps without text messages
The following indicator lamps indicate that cer-
tain functions are activated:
With parking brake set61
With parking brake set for Canadian
models
Fog lamps105
High beams/headlamp flasher104
Lamp flashes:
DSC or DTC controls the drive and
braking forces for maintaining vehicle
stability89

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 panorama 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 stacking garages
>When transporting on car-carrying trains,
by sea 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*
Comfort access enables you to access your
vehicle without having to hold the remote con-
trol in your hand. It is sufficient to carry the
remote control with you, e.g. in your jacket
pocket. The vehicle automatically detects the
related remote control in the immediate vicinity
or in the interior.
Comfort access supports the following func-
tions:
>Unlocking/locking vehicle
>Comfort closing
>Opening liftgate>Starting engine
Functional requirements

Tachometer
Do not operate the engine with the needle in the
red overspeed zone of the gauge, refer to arrow.
At high revs in this range, the flow of fuel is
interrupted to protect the engine.
Coolant temperature
Should the coolant, and with it the engine
become too hot, a warning lamp lights up. In
addition, a message appears on the Control
Display.
Checking coolant level, refer to page244.
Energy Control
Displays the current fuel consumption. This
allows you to see whether your current driving
style is conducive to fuel economy with mini-
mum exhaust emissions.
Fuel gauge
Fuel tank capacity: approx. 22.5 US gal/
85 liters. You will find information on refueling
on page232.
If the tilt of the vehicle varies for a longer period,
when you are driving in mountainous areas, for
example, the indicator may fluctuate slightly.
Reserve
After the reserve quantity has been reached, a
message briefly appears on the Control Display;
the remaining range is shown in the computer.
Below a range of approx. 30 miles/50 km, the
message remains on the Control Display.

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.
However, an acoustic warning first sounds for
the sensors at the front and at the two rear cor-
ners 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 physical circumstances would mean
that the system warning was too late.<
Automatic activation
Whenever the engine is running or the ignition
is on, each time you move the selector lever into
position R, the PDC system is activated after
approx. 1 second.
Wait this short period before driving off.
Manual activation
Press the button, the LED lights up.
Manual deactivation
Press the button again; the LED goes out.
Automatic deactivation
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
When nearing an object, the position is corre-
spondingly indicated by an interval tone. 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. If the dis-
tance to the nearest object falls to below
roughly 1 ft/30 cm, then a continuous tone
sounds.
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
Adjusting
You can adjust the volume of the warning tones
if the vehicle is equipped with a single drive,
refer to page83.
Malfunction
The LED in the button flashes and a message
appears on the Control Display. PDC is mal-
functioning. 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. Do
not spray the sensors with high-pressure clean-
ers for long periods and maintain a distance of
at least 4 in/10 cm to them.

Rear view camera*
The concept
The rear view camera in the liftgate displays the
area behind your vehicle on the Control Display.
Also check the traffic situation around the
vehicle during parking and maneuvering
with direct vision, as otherwise danger of an
accident could result, for example, from road
users or objects located outside the picture
area of the rear view camera.<
Switching on
Automatically
With the engine running, shift into reverse.
If the image of the Park Distance Control
PDC appears in the Control Display, you
can switch the image to the rear view camera,
refer to Displays on page88.<
Manually
Press the button.
PDC is activated at the same time, refer to
page84.
If the image of the Park Distance Control
PDC appears in the Control Display, you
can switch the image to the rear view camera,
refer to Displays on page88.<
Switching off
Automatically
When driving forward at over approx. 12 mph/
20 km/h or after driving approx. 164 ft/50 m.
Manually
Press the button again; the LED goes out.
Driver assistance functions
The following functions can improve the effect
of the rear view camera depending on the situa-
tion.
They can only be activated when the tailgate
and liftgate are completely closed.
Pathway lines
The pathway lines are shown in the picture of
the rear view camera. They help you to estimate
the space required when parking and maneu-
vering on level roads.
To estimate the space required, turn the steer-
ing wheel so that the pathway lines guide into
the parking space or the maneuvering area you
have chosen.
The pathway lines are dependent on the current
steering angle and are continuously adjusted to
the steering wheel movements.
Turning lines
The static turning lines are displayed in the pic-
ture of the rear view camera and show you the
course of the smallest possible turning circle on
level roads.

5.Change to upper field if necessary. Turn the
controller until "FTM" is selected and press
the controller.
6.Start the engine, but do not start driving.
7.Select "Reset" and press the controller.
8.Select "Yes" and press the controller. The
message "resetting FTM …" is displayed.
9.Start to drive.
The initialization finishes during driving.
Indication of a flat tire
The warning lamp lights up 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.
If you have deactivated DSC, it will be activated
automatically.
1.Cautiously reduce speed to below 50 mph/
80 km/h. Avoid sudden braking and steer-
ing maneuvers. Do not exceed a speed of
50 mph/80 km/h.
In case of further air loss of the defective
wheel, its position will be indicated to you
on the Control Display.If the vehicle is not equipped with run-
flat tires as provided at the factory,
refer to page239, do not continue driving.
Continuing to drive with a flat tire could
cause severe accidents.<
2.At the next opportunity, check the air pres-
sure in all four tires.
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 the basis
of the following guide values:
>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. 95 miles/150 km
>With a full load:
4 or more persons, cargo bay full:
approx. 30 miles/50 km
Drive cautiously and do not exceed
speeds of 50 mph/80 km/h or else you
run the risk of causing 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 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 location as soon as possible,
otherwise pieces of the tire could become
detached and cause an accident. Do not con-
tinue driving, but instead contact the BMW
Sports Activity Vehicle Center.<
