PDC Park Distance Control
* Antilock Brake System
Signal tones The distance from an object is indicated
in front with a higher intermittent tone,
and at the rear with a lower intermittent
tone. 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.
The warning signal is canceled after
approx. 3 seconds if you are moving
parallel to a wall. MalfunctionsThe LED flashes and a short steady sig-
nal tone is sounded
>if you activate PDC with the button
>when you select reverse for the first
time after switching on the ignition
>if a malfunction occurs while the PDC
system is active.
Switch the system off and have the
cause of the malfunction corrected by
your BMW Sports Activity Vehicle cen-
ter.
System limits
Even with PDC, final responsibility
for estimating the distance
between the vehicle and any obstruc-
tions always remains with the driver.
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. It is also possible that low
objects already displayed, such as curb
edges, may come into the blind spot of
the sensors before a continuous signal
sounds or that higher, protruding
objects, such as ledges, will not be
detected.
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 will continue to operate effec-
tively.
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 sensors.<
The concept The ABS Antilock Brake System pre-
vents the wheel brakes from locking
during braking. Safe steering response
is maintained even during full braking.
This increases active safety.
The ABS is operational every time you
start the engine. Safe braking, refer to
page 140.EBV Electronic brake-force
distribution EBV controls the brake system's appli-
cation pressure at the rear wheels to
ensure stable deceleration.DBC Dynamic Brake Control When the brake pedal is depressed
rapidly, this system automatically gen-
erates a maximum boost of braking
force and thus aids in keeping braking
distances as short as possible during
full braking. This system exploits all of
the benefits provided by ABS.
Do not reduce the pressure on the
brake pedal for the duration of the
brake application. DBC is deactivated
when you release the brake pedal.

Antilock Brake System DSC Dynamic Stability Control MalfunctionsPlease 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 taking unneces-
sary risks.<
Indicator lamp
The indicator lamp in the instru-
ment cluster goes out shortly
after the engine is started.
The indicator lamp flashes:
DSC is active and is regulating 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.

DSC Dynamic Stability ControlSwitching DSC offPress the button; the indicator lamp
comes on and stays on.
Stabilizing interventions of the chassis
control system DSC are no longer avail-
able. However, the braking interven-
tions that simulate the function of the
differential lock continue to be active.
In the following exceptional circum-
stances, it may be effective to switch off
the DSC for a short period:
>When rocking a stuck vehicle free
and when starting off in deep snow or
on loose road surfaces
>On sandy road surfaces
>On poor surfaces with deep ruts 530de414
>If the wheels churn on muddy sur-
faces
>When driving with snow chains.
When the DSC system is switched
off, braking maneuvers may sub-
ject the brakes to additional loads.
Automatic limitation of braking action
may briefly occur in order to limit brake
temperatures.
To maintain vehicle stability, always
drive with the system switched on when
possible.<
Switching DSC on Press the button a second time – the
indicator lamp goes out. DSC is now
activated.MalfunctionsPlease be sure to read the information
on the DSC Dynamic Stability Control/
xDrive warning lamp on page 22 and on
the possible lamp combinations that

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.MalfunctionsPlease be sure to read the information
on the DSC Dynamic Stability Control/
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 LED lights up.
The LED flashes when the brakes are
applied automatically. Deactivating system Press the button again; the LED 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

Using HDC With manual transmission:
Use HDC in first gear and in Reverse
since the engine's braking action is
diminished in the higher gears.
With automatic transmission:
You can use HDC in every drive posi-
tion. In case of a malfunction If the LED in the button goes out during
HDC operation or does not light up
when the HDC is activated:
HDC is temporarily unavailable due to
excessive brake temperature. The warning lamp for the self-
leveling suspension comes on,
or the message SELFLEVEL
SUSP.INACT appears in the Check
Control: there is a malfunction in the
self-leveling suspension.
Stop and inspect the vehicle. If the rear
of the vehicle is visibly lower than the
front, possibly accompanied by a tilt
noticeable when you compare the left
rear with the right rear, please respond
by immediately proceeding to the near-
est BMW Sports Activity Vehicle center.
Drive with appropriate caution in the
meantime. The vehicle has reduced
ground clearance and driving comfort
may be noticeably reduced.
Even when the position of the vehicle is
normal, have the system checked as
soon as possible when a malfunction is
indicated.

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 97, 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.
The ground clearance of the vehicle
6.5-9 in/16.5-22 cm, depending on the
level selected.
Frequent changes in ride height
initiated at short intervals can
overheat the compressor, causing the
system to briefly suspend active opera-
tion.<

Brake force display Flat Tire MonitorThe brake lamps light up in two stages,
depending on how forcefully you apply
the brakes.
>Normal braking:
The brake lamp 1 and the center
brake lamp light up
>Heavy braking:
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 in
one tire drops significantly in relation to
the pressure in 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 in the drive wheels, high
lateral acceleration
>False alarms and undetected loss of
pressure may occur when you are
driving with snow chains fitted.

change a wheel or all wheels. The vehi-
cle must be driven during initialization.<
1. Start the engine, but do not begin to
drive immediately.
2. Press the button until the yellow indi-
cator lamp in the instrument cluster
lights up for a few seconds.
3. Begin driving.
530de419
It takes a few minutes of driving before
the Flat Tire Monitor can detect and
report a flat tire.
When driving with snow chains,
do not initialize the system.<
Indication of a flat tire
The warning lamp lights up yel-
low. There is a flat tire or exten-
sive inflation pressure loss.
1. Reduce speed and stop the vehicle
carefully. Avoid sudden braking and
steering maneuvers
2. Identify damaged tire
If identification is not possible,
contact your BMW Sports
Activity Vehicle center.<
3. Replace the damaged wheel, refer to
Changing a wheel on page 165.

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
page101.
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, an acoustic signal will sound
for a few seconds to remind you that
the lamps have not been switched off.
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.<
