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repealed, even with DSC.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 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

HDC Hill Descent Control Self-leveling suspension
*
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.

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.

Moving parts should be allowed to
break in. To ensure that your vehicle
provides maximum economy through-
out a long service life, we request that
you comply with the following instruc-
tions:
Engine and differential Obey your local and state maximum
speed limits.
Up to 1,200 miles/2,000 km:
Drive at varying engine speeds and
road speeds, but do not exceed
4,500 rpm and the following road
speeds during this initial period:
>6-cylinder engine
100 mph/160 km/h
>8-cylinder engine
106 mph/170 km/h
Avoid full-throttle operation and use of
the transmission's kick-down mode
during these initial miles.
From 1,200 miles/2,000 km:
The engine and vehicle speed can
gradually be increased.
Tires Due to technical factors associated with
their manufacture, tires do not achieve
their full traction potential until after an
initial break-in period. Therefore, drive
reservedly during the first 200 miles/
300 km.
Obey your local and state maximum
speed limits.
When the vehicle is operated on
wet or slushy roads, a wedge of
water may form between the tire and
the road surface. This phenomenon is
referred to as hydroplaning and can
lead to partial or complete loss of trac-
tion, vehicle control and braking effec-
tiveness. Reduce your speed on wet
roads.< Brake system Brakes require an initial break-in period
of approx. 300 miles/500 km to achieve
optimal contact and wear patterns
between brake pads and rotors.
To break in the separate handbrake
drums, apply the handbrake lightly
when coasting to a standstill at a traffic
signal, for instance, provided that traffic
conditions allow you to do so.
To avoid corrosion, repeat this proce-
dure from time to time.
The brake lamps do not light up
when the handbrake is applied.
Vacuum for the brake system servo unit
on your BMW is available only when the
engine is running. When you move the
vehicle with the engine switched off,
when towing, for instance, substantially
higher levels of pedal force will be
required to brake the vehicle.< ClutchThe function of the clutch is only at its
optimized level after a distance driven
of approx. 300 miles/500 km. During
this break-in period, engage the clutch
gently.Following component
replacementsObserve the break-in instructions again
if previously addressed components
must be replaced again during subse-
quent driving.

General driving notesClosing liftgate/tailgate
Operate the vehicle only when the
tailgate and liftgate are completely
closed. Otherwise, exhaust fumes
could enter into the passenger com-
partment.<
However, if special circumstances
should make it absolutely necessary to
operate the vehicle with the liftgate/tail-
gate open:
1. Close all windows and the panorama
glass roof
2. Increase the air supply for the air
conditioner or automatic climate
control to a high level, refer to
page105 or109.
Hot exhaust system
Extreme temperatures occur on
the exhaust system on any vehi-
cle. Do not remove the heat shields
installed adjacent to it, and never apply
undercoating to them. When driving,
standing at idle and while parking, take
care to avoid possible contact between
a hot exhaust system and any highly
flammable materials such as hay,
leaves, grass etc. Otherwise, there is a
danger of ignition and fire, with the risk
of serious injuries and damage.<
Mobile communications devices
in vehicle
BMW advises against using
mobile communications devices
such as mobile phones inside the vehi-
cle unless they are directly connected
to the external antenna. Otherwise, it is
impossible to prevent a mutual interfer-
ence of the vehicle electronics with the
mobile phone device. Also, there is no
guarantee that the radiation generated
by the transmission will be conveyed
out from the interior of the vehicle.<
When vehicle is parked Condensation forms in the air condi-
tioner system during operation and then
exits under the vehicle. Traces of water
on the ground are therefore normal.Brakes
Do not drive with your foot resting
on the brake pedal. Even light but
consistent pedal pressure can lead to
excessively high temperatures, brake
wear and possibly even brake failure.<
Road hazards
If road hazards, obstacles or curbs
are unavoidable, only drive over
them very slowly and carefully, other-
wise the wheels and suspension parts,
especially on vehicles fitted with low
profile tires, can be damaged.<
For more information on wheels and
tires, refer to page146.
Before driving into a car washFold in the exterior mirrors, refer to
page53, otherwise they could be dam-
aged due to the width of the vehicle.Hydroplaning
When driving on wet or slushy
roads, reduce road speed. If you
do not, a wedge of water can form
between tires and road surface. This
state can cause a partial or total loss
of contact with the road surface, of
braking control and of control over the
vehicle.<

General driving notes Driving your X5 Driving through water
Do not drive through water on the
road if it is deeper than 20 in/
50 cm, and then only at walking speed
at the most. Otherwise, the vehicle's
engine, the electrical systems and the
transmission may be damaged. When
equipped with 2-axle self leveling sus-
pension
*, switch the vehicle into the
Off-Road setting before driving through,
refer to page97.<
Using handbrake on slopes
Do not hold the vehicle in place on
slopes by slipping or riding the
clutch; use the handbrake instead. Oth-
erwise, severe clutch wear will result.<
Interior and exterior mirrors,
automatic dimming feature
*
Two photocells serve to control the
automatic dimming of the interior and
exterior rearview mirrors. One photocell
is in the mirror glass, refer to arrow,
while the other is on the back of the
mirror, offset somewhat from the first.
For trouble-free operation, keep the
photocells clean and do not cover the
area between the interior rearview mir-
ror and the windshield. Do not attach
any kind of stickers to the windshield in
front of the mirror either. 530us245
On poor roads When you are driving on poor roads,
there are a few points which you should
strictly observe — for your own safety,
for that of your passengers, and for the
safety of the vehicle:
Driving on unpaved terrain can
cause damage to the vehicle.<
>Always adapt the driving speed to the
road conditions. The rougher or
steeper the road surface is, the lower
the speed should be
>You can operate your vehicle on
uphill and downhill gradients with a
maximum slope of 50 %. If you want
to drive on uphill or downhill gradi-
ents of this kind, make sure before-
hand that the engine oil and coolant
levels are near the max mark, refer to
pages152 and154.
Use the HDC Hill Descent Control
when driving down steep grades,
refer to page94.
It is possible to start off on grades of
up to 33 %.
The permissible body roll is also 50 %
>While driving, watch carefully for
obstacles such as rocks or holes. Try
to avoid these obstacles whenever
possible
