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

Using 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 posi-
tion. In case of a malfunction If the warning lamp in the button goes
out during HDC operation or does not
light up when the HDC is activated:
HDC is temporarily not available as
brake temperature is too high. 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 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.<

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.

102n
Flat Tire MonitorInitializing system
Perform the initialization immedi-
ately every time you correct the
inflation pressure, change a tire or
change a wheel or all wheels. A drive
is required for this purpose.<
1. Before the start of driving, start the
engine, but do not drive off
2. Press the button until the yellow indi-
cator lamp in the instrument cluster
lights up for a few seconds
3. Drive off.
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.<
530de419
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
Wheel changes on page 163.

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.<

High beams/roadside parking lamps
The concept Adaptive Head Light is a variable head-
lamp control system that enables better
illumination of the road surface.
Depending on the steering angle and
other assumptions, the light from the
headlamp follows the course of the
road.Activating Adaptive Head Light
In ignition key position 2, turn
the light switch to the position
'Automatic headlamp control',
refer to page103.
To avoid blinding oncoming traffic, the
Adaptive Head Light
>is not active when driving in reverse
>is active only when pointing toward
the passenger side.
MalfunctionThe LED next to the symbol for auto-
matic headlamp control flashes. Adap-
tive Head Light is faulty or has failed.
Have the system checked as soon as
possible.

parking, if you wish to do so:
With the ignition key in position 0,
engage the lever in the appropriate turn
signal position.
The roadside parking lamps
drain the battery. Avoid use for
extended periods of time, otherwise, it
will no longer be possible to start the
engine.<530de265
