PDC
* Dynamic Stability Control DSC
The PDC system does not remove
the driver's personal responsibility
for evaluating the distance between the
vehicle and any objects. Even when
sensors are involved, there is a blind
spot in which objects cannot be
detected. This applies especially in
those cases where the system
approaches the physical constraints of
ultrasonic measurement, as occurs with
tow bars and trailer couplings, and in
the vicinity of thin or wedge-shaped
objects. Similarly, low objects that have
already been detected - e.g. a curb-
stone - may disappear out of the range
of the sensors before a continuous tone
is emitted.
Loud sources of sound, inside and out-
side the vehicle, could drown out the
PDC signal tone.<
Keep the sensors clean and free
of ice or snow in order to ensure
that they continue to operate effectively.
Do not apply high pressure spray to the
sensors for a prolonged period of time.
Maintain an adequate distance of more
than 4 in/10 cm.<
The concept DSC maintains vehicle stability, even in
critical driving situations.
The system optimizes vehicle stability
during acceleration and when starting
from a full stop, as well as optimizing
traction. In addition, it recognizes
unstable vehicle conditions, such as
understeering or oversteering, and, as
far as is possible within the laws of
physics, keeps the vehicle on a steady
course by adapting the rpms and brake
applications to the individual wheels.
The system starts up automatically
each time you start the engine.
Indicator lamp
The indicator lamp in the instru-
ment cluster goes out shortly
after you switch on the ignition,
refer to page 21.
Indicator lamp ßashes:
The system is active and governs drive
and braking force.
If the indicator lamp fails to go out after
the engine is started, or comes on
during normal driving and stays on:
The system is either defective or was
switched off with the button: the stabi-
lizing applications described to the left
are no longer available. The vehicle will
remain completely operational, how-
ever, without DSC.
Consult your BMW Sports Activity
Vehicle center to have the system
repaired.

Dynamic Stability Control DSCTo switch the system offPress the button; the indicator lamp
comes on and stays on.
Traction intervention remains active;
that is, braking intervention will con-
tinue.
In the following exceptional circum-
stances, it may be effective to switch
off the DSC for a short period:
>When rocking the vehicle or starting
off in deep snow or on loose surfaces
>On sandy road surfaces
>On poor surfaces with deep ruts
>If the wheels churn on muddy
surfaces
>When driving with snow chains. 530de230
As a result of the traction interven-
tion, the brakes may be subjected
to additional loads when the system is
switched off. For this reason, it is pos-
sible that the braking intervention will
be disabled automatically for a brief
period in order to limit brake tempera-
ture.
To maintain vehicle stability, always
drive with the system switched on when
possible.<
To switch the system on againPress the button again; the indicator
lamp goes out.
The laws of physics cannot be
repealed, even with DSC. An
appropriate driving style always
remains the responsibility of the driver.
We therefore urge you to avoid using
the additional safety margin of the
system as an excuse for taking risks.
Do not make any modifications to the
DSC system. Service procedures on
the system are to be performed by
authorized technicians only.<
Dynamic Brake Control DBCDBC is an integral component of the
DSC system.
The system responds to sudden, high-
intensity applications of force to the
brake pedal by automatically braking
the vehicle with maximum boost to
achieve the shortest-possible braking
distances during panic stops. This
system exploits all the benefits of ABS.
Do not reduce the pressure exerted
against the brake pedal until the
braking maneuver has been completed.
DBC is deactivated when you release
the brake pedal.

Hill Descent Control HDC The concept HDC is a system for driving downhill in
steep terrain. This system reduces
vehicle speed on steep downhill gradi-
ents, thus allowing you to maintain con-
trol of your BMW under these condi-
tions.
The vehicle moves at slightly more than
walking speed without active interven-
tion from the driver.
HDC is available for activation at
vehicle speeds below approx. 20 mph/
35 km/h. When driving down steep hills
with a speed below approx. 20 mph/
35 km/h, the vehicle reduces speed
automatically down to slightly more
than walking speed (approx. 5 mph/
8 km/h) and then maintains this speed
at a constant.
You can use the accelerator or brakes
to vary this automatically controlled
speed within a range extending from
approx. 3 mph/5 km/h to 15 mph/
25 km/h.
You can specify a target speed
within the same range by using the
+/Ð buttons of the cruise control.
HDC is automatically deactivated once
vehicle speed again exceeds approx.
35 mph/60 km/h.
To switch the system onPress the button. The indicator lamp
comes on.
The indicator lamp flashes when the
brakes are applied automatically. To switch the system offPress the button again; the indicator
lamp goes out.
HDC is deactivated automatically above
a road speed of approx. 35 mph/
60 km/h and when the ignition is
switched off. 530de231
To use HDC With manual transmission:
Use HDC in first gear and in Reverse
since the engine's braking effect is
diminished in the higher gears.
With automatic transmission:
You can use HDC in every drive
position. In the event of a faultThe indicator lamp goes out in the HDC
mode or does not come on when HDC
is switched on:
HDC is temporarily not available if
brake temperature is too high.
If the DSC indicator lamp also
lights up:
There is a fault in the HDC and
DSC systems. Have your BMW Sports
Activity Vehicle center inspect this
system as soon as possible.

The warning lamp for the self-
leveling suspension comes on,
or the message Ð SELFLEVEL
SUSP.INACT Ð appears in the Check
Control: there is a malfunction in the
self-leveling suspension.
Stop and inspect the vehicle. If it is
riding significantly lower in the rear than
in the front, or if it is sitting at an incline
Ð left rear compared to right rear - con-
sult the nearest BMW Sports Activity
Vehicle center. Drive with appropriate
caution in the meantime. The vehicle
has reduced ground clearance or
driving comfort is noticeably reduced.
Even if the attitude of the vehicle is
normal, you should consult the nearest
BMW Sports Activity Vehicle center if
the warning lamp indicates a system
malfunction.
The conceptYour vehicle is equipped with 2-axle
self-leveling suspension acting on both
the front and rear suspension. This
system combines automatic self-lev-
eling, which compensates for variations
in front-to-rear load-distribution pat-
terns, with a selection feature allowing
drivers to choose from among several
ride-height options.
You may choose from among the fol-
lowing ride heights:
>Standard
The standard setting is intended for
most operating conditions, including
trailer towing
>Off-Road
Higher ride height for increased
ground clearance
>Access
Lowers vehicle for more convenient
cargo handling or easier passenger
ingress and exitsChanges in ride height are initiated
either manually, using the control
button, refer to page 95, or automati-
cally in response to specific speeds.
When the ride height is selected manu-
ally, the driver has the additional option
of revising the ride-height selection by
entering a new command during the
adjustment process.
When the vehicle is stationary, the
system executes ride-height changes in
both directions (up and down) when-
ever the doors are closed. The tailgate/
liftgate may be open. The system raises
the vehicle only when the engine is run-
ning.
The system's automatic self-leveling
feature automatically compensates for
variations in the vehicle's load.
Frequent changes in ride height
initiated at short intervals can
overheat the compressor, causing the
system to briefly suspend active opera-
tion.<

Tire Pressure Monitor RDC*The conceptRDC monitors the tire pressures at all
four tires, even when the vehicle is
moving. The system provides an alert
whenever the inflation pressure drops
significantly below the specified pres-
sure in one or more tires.
In order for the system to learn the cor-
rect tire inflation pressure, check the
inflation pressures in all tires, refer to
the table on page 27 and make any
necessary corrections. Then activate
the system.
This indicator lamp in the instru-
ment cluster or the Check Con-
trol will inform you if the tire
pressure is different from the learned
values.
To switch the system on1. Turn the ignition key to position 2, do
not start the engine
2. Maintain pressure on the button until
the yellow indicator lamp in the
instrument cluster comes on for sev-
eral seconds or the message Ð TIRE
PRESSURE SET Ð appears in the
Check Control
3. After you have driven for a few min-
utes, the RDC will import the current
inflation pressure in the tires as the
reference values which the system
will monitor.
You will only have to repeat this proce-
dure if the tire inflation pressure must
be corrected. Otherwise, the RDC func-
tions automatically when the ignition
key is in position 2, and thus operates
whenever the vehicle is driven.530de232
Loss of tire pressureIf, after a certain period of time, the
inflation pressure has gone down sig-
nificantly, which is normal for any tire,
the yellow indicator lamp comes on or
the message Ð CHECK TIRE PRES-
SURE Ð appears in the Check Control.
This alerts you that you should have the
tires inflated to the specified pressures
as soon as possible.
If you are prompted to check the
tire pressure shortly after a cor-
rection has been made, this indicates
that the corrected values were not
accurate. Please check the inflation
pressure again and make corrections
according to the inflation pressure
table. After that reactivate the system.<

Adaptive brake light
Flat tireIf there is a tire failure with a loss of
inflation pressure, the red indicator
lamp comes on or the message Ð TIRE
LOW/FLAT Ð appears in the Check
Control. In addition, an acoustic signal
sounds.
If this occurs, reduce vehicle speed
immediately and stop the vehicle in a
safe location. Avoid hard brake applica-
tions. Do not oversteer. Replace the flat
tire.
The spare tire which is available in
your vehicle as standard equip-
ment is equipped with the electronics
required for RDC and, following activa-
tion of the system, is also monitored
after it is mounted.<
RDC cannot alert you to severe
and sudden tire damage caused
by external factors.<
Have the tires changed at your
BMW Sports Activity Vehicle
center.
Your BMW Sports Activity Vehicle
center has the information needed for
working with RDC and is equipped with
the necessary special tools.<
System malfunctionDuring the period of the malfunction,
the yellow indicator lamp comes on or
the message Ð TIRECONTROL INAC-
TIVE Ð appears in the Check Control.
You will also see the same message
>in the event of a system malfunction
>if a wheel is mounted without the
RDC electronics
>if, in addition to the spare tire, addi-
tional wheels with RDC electronics
are on board
>after installation of one or several
wheels with an electronics system
still unknown to the system.
It takes a few minutes to learn the
new wheel electronics ID numbers
after system activation. Only then can
RDC detect and report a flat tire.
Please contact your BMW Sports
Activity Vehicle center for additional
information.The adaptive brake light provides
drivers of following vehicles with an
indication of the intensity with which
the brakes are being applied in your
own vehicle.
The display occurs in two stages:
>Normal braking:
The brake light units within the tail
lamps and the high-mount brake
lamp integrated within the rear
spoiler both light up with normal
intensity
>Hard braking or braking with ABS
active:
The tail lamps also come on, lighting
up with the same intensity as the
brake lamps to provide a more con-
spicuous warning.

Automatic headlamp control
cannot serve as a substitute for
the driver's judgement in determining
when the vehicle lamps should be
switched on. For example, the sensors
are not able to detect fog. To avoid
safety risks, you should respond to
these kinds of low-visibility situations
by switching the headlamps on manu-
ally.<
