PDC Park Distance Control
*
The concept PDC provides extra safety and conve-
nience during parking maneuvers. Sig-
nal tones indicate the current distance
to an object behind or in front of your
vehicle. To do this, four ultrasonic sen-
sors in the front and rear bumpers each
measure the distance to the nearest
object. The detection range of the front
sensors and the two sensors located at
the ends of the rear bumper is approx.
2 ft/60 cm, while the rear center sen-
sors can detect objects to a distance
of 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
objects too fast, otherwise the system
may give warning of physical obstacles
too late.<
Automatic operationThe system starts to operate automati-
cally approx. one second after you
select reverse or move the selector
lever into the R position with the ignition
key in position 2. Wait this short period
before backing up. The system
switches off when you shift back out
of reverse.
Manual activation Press the button, the indicator lamp
lights up. Manual deactivation Press the button again; the indicator
lamp goes out.Automatic deactivationAfter driving a distance of more than
approx. 160 ft/50 m or exceeding a
speed of approx. 20 mph/30 km/h, the
system switches off and the indicator
lamp goes out. You may switch the sys-
tem on again manually as needed. 530de418

Antilock Brake System DSC Dynamic Stability Control MalfunctionPlease be absolutely sure to follow
instructions regarding possible combi-
nations of indicator lights on page 20.
The concept DSC prevents the drive wheels from
slipping when starting off and acceler-
ating. DSC also identifies unstable driv-
ing conditions, such as a loss of trac-
tion at the rear of the vehicle or sliding
of the vehicle in its front wheels. Under
these circumstances, DSC helps the
vehicle maintain a safe course within
the physical limits by reducing the
engine output and by applying the
brakes in the individual wheels.
The DSC is operational every time you
start the engine.
The laws of physics cannot be
repealed, even with DSC.
An appropriate driving style always
remains the responsibility of the driver.
So please do not further limit the addi-
tional safety margin by risky driving.<
Indicator lamp
The indicator lamp in the instru-
ment cluster goes out after the
engine is started.
The indicator lamp flashes:
DSC is active and governs drive and
braking force.
The indicator lamp stays lit:
DSC has been switched off using the
button and the stabilizing interventions
are no longer available.

xDrive HDC Hill Descent Control xDrive is the 4-wheel drive system of
your X5. The combined effects of xDrive
and DSC further optimize the traction
and dynamic driving characteristics.
The 4-wheel drive system xDrive vari-
ably distributes the drive torque to the
front and rear axle depending on the
driving situation and prevailing road
conditions.MalfunctionPlease be sure to observe the informa-
tion on the DSC Dynamic Stability Con-
trol/xDrive warning lamp on page 22
and on the possible lamp combinations
that can light up on page 20.
The concept HDC is a system for driving downhill in
steep terrain. This system reduces vehi-
cle speed on steep downhill gradients,
thus allowing you to maintain even bet-
ter control of your BMW under these
conditions.
The vehicle moves at slightly more than
walking speed without active interven-
tion from the driver.
HDC is available for activation at vehi-
cle 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 +/– but-
tons of the cruise control.
HDC is automatically deactivated once
vehicle speed again exceeds approx.
35 mph/60 km/h.
Activating system Press the button, the indicator lamp
lights up.
The indicator lamp flashes when the
brakes are applied automatically. Deactivating system Press 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. 530de416

2-axle self-leveling suspension
*
The concept Your vehicle is equipped with 2-axle
self-leveling suspension acting on both
the front and rear suspension. This sys-
tem combines automatic self-leveling,
which compensates for variations in
front-to-rear load-distribution patterns,
with a selection feature allowing drivers
to choose from among several ride-
height options.
You may choose from among the fol-
lowing ride heights:
>Normal
The standard setting is intended for
most operating conditions, including
trailer towing
>Off-Road
Increased level for more ground
clearance
>Access
Lowers vehicle for more convenient
cargo handling or easier passenger
entries and exits.
Changes in ride height are initiated
either manually, using the control but-
ton, refer to page 100, or automatically
in response to specific speeds. When
the ride height is selected manually, the
driver has the additional option of revis-
ing the ride-height selection by entering a new command during the adjustment
process.
When the vehicle is stationary, the sys-
tem 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.<

The LEDs not only show the current ride
height, but also indicate changes:
>LED on: indicates the vehicle's cur-
rent ride height
>Ride-height LED flashes while the
LED for the earlier level remains on:
the ride height is being adjusted to a
new level, either automatically or in
response to driver input at the button.
When the suspension reaches the new
ride height the flashing LED reverts to
continuous operation, and the LED for
the earlier level goes out530de218

Brake Force Display Flat Tire MonitorThe Brake Force Display lights up in
two stages, depending on how force-
fully you apply the brakes.
The display has two levels:
>Normal braking:
The brake lamp 1 and the center
brake lamp light up
>Heavy braking and braking with ABS:
The brake lamps 1 and 2 light up
together with the center brake lamp.530de400
The concept The Flat Tire Monitor keeps track of the
inflation pressures in the four fitted tires
as you drive. The system provides an
alert whenever the inflation pressure
drops significantly in relation to the
pressure another tire.
The check of the tire inflation pressure
is based on monitoring the relative
speeds of the wheels. A flat is detected
and reported on the basis of a deviation
in certain speed ratios.Functional requirementTo ensure reliable operation, the sys-
tem should have been initialized with
the correct tire inflation pressure.
System limits
The Flat Tire Monitor cannot indi-
cate 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:
>When driving on snow-covered or
slippery road surfaces
>In the case of performance-oriented
driving: slip on the drive wheels, high
lateral acceleration
>False alarms and undetected loss of
pressure may occur when you are
driving with snow chains fitted.

Parking lamps/side marker lamps
The front, rear and side vehicle
lighting is switched on. You can
use the parking lamps for park-
ing. For lighting on one side for parking
as an additional feature, refer to
page104.
Low beams
When the ignition is switched off
and the low beams are on, only
the parking lamps/side marker
lamps remain on.
530us215
Pathway lighting:
When you activate the headlamp
flasher after parking the vehicle and
switching off the lamps, the low beams
will come on for a brief period. You may
also have this function deactivated if
you wish.<
Lights on warning Whenever you open the driver's door,
after having turned the ignition key to
position 0, you will hear an acoustic sig-
nal for a few seconds to remind you that
the lamps have not been switched off.
On vehicles with alphanumeric Check
Control
*:
The reminder is given through the
Check Control.
Daytime driving lamps
*
The headlamps are automatically
switched on for daytime driving at igni-
tion key position 2.
Automatic headlamp control
*
When you set the switch to this
position, the system activates
and switches on and off the low
beams in response to changes in ambi-
ent light conditions, for instance, in tun-
nels, at dawn and dusk, and in rain and
snow.
The low beams remain switched
on regardless of the ambient light
when you switch on the front fog
lamps.<
Automatic headlamp control can-
not serve as a substitute for the
driver's judgment in determining when
the vehicle lamps should be switched
on. For example, the system cannot
detect fog. To avoid safety risks, you
should always switch on the lamps
manually under these conditions.<
You can have the sensitivity of the
headlamp control system adjusted
on your vehicle.<
