Handbrake Manual transmissionThe handbrake is primarily intended to
prevent the vehicle from rolling while
parked; it brakes the rear wheels.EngagingThe lever engages automatically when
you pull it up and the indicator lamp
comes on in the instrument cluster in
ignition key position 2, refer to
pages19, 21.Releasing Pull up slightly on the lever, press the
button and lower the lever. 530de262
If exceptional circumstances
should make it necessary to
engage the handbrake while the vehicle
is in motion, do not pull it too strongly.
In doing so, continuously press the but-
ton of the handbrake lever.
Excessive pressure can lead to over-
braking and loss of traction – fishtailing
– at the rear axle.
The brake lamps do not light up when
the handbrake is applied.
Vehicles with manual transmission:
Always engage the handbrake when
parking on slopes and inclined sur-
faces. Even placing the gearshift lever
in 1st gear or reverse may not provide
adequate resistance to rolling.
Vehicles with automatic transmission:
Place the selector lever in Park.<
To avoid corrosion, apply the hand-
brake lightly from time to time when
coasting to a standstill at a traffic signal,
for instance, provided that it is safe to
do so.
Press the clutch pedal all the way down
each time you shift, pressing the gear-
shift lever into its proper end position.
Depress the clutch when starting the
vehicle, too, otherwise, the interlock will
prevent the engine from starting if the
clutch is not depressed.
While shifting in the 5th/6th gear
lane, press the selector lever
toward the right, as otherwise acciden-
tal shifting into the 3rd or 4th gear could
result in engine damage.< 380de044

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. MalfunctionThe indicator lamp flashes and a short
steady signal 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. Low objects already displayed,
e.g. a curb, can also disappear from the
detection area of the sensors again
before a continuous tone sounds.
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 effectively.
Do not apply high pressure spray to the
sensors for a prolonged period of time.
Keep the spray 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 maximal boost of braking force
and thus aids in keeping braking dis-
tances 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 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.

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 the vehicle and 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.
As a result of the braking inter-
ventions, the brakes may be sub-
jected to additional loads when the sys-
tem is switched off. In order to limit the
brake temperature, brief automatic
masking of the brake activation is pos-
sible.
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.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 20.530de414

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

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.

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 observe the following instructions:
Engine and differential 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 engines: 100 mph/160 km/h
8-cylinder engines: 106 mph/170 km/h
Obey your local and state maximum
speed limits.
Avoid full-throttle operation and use of
the transmission's kick-down mode
during these initial miles.
Once you have driven 1,200 miles/
2,000 km, the engine and vehicle
speeds can be gradually 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 driving
later.

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/
tailgate open:
1. Close all windows and the panorama
glass sunroof
2. Increase the air supply for the air
conditioner or automatic climate
control to a high level, refer to
page108 or112.
Hot exhaust system
Extreme temperatures occur at
the catalytic converter on this and
every catalyst-equipped vehicle. Do not
remove the heat shields installed adja-
cent to various sections of the exhaust
system, 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 mate-
rials such as hay, leaves, grass etc.
Otherwise there is a danger of ignition
and of a fire with the risk of serious inju-
ries and damage. BMW advises against using
mobile radio devices such as por-
table phones inside the vehicle 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
portable 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 nor-
mal.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, as oth-
erwise 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 page144.
Before driving into a car washFold in the exterior mirrors, refer to
page54, as otherwise they could be
damaged due to the width of the vehi-
cle.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 brak-
ing control and of control over the vehi-
cle.<

Driving your X5>Please note that, for example on
crests and bumpy roads, the body
can make ground contact.
The ground clearance of the vehicle
is:
– 8 in/20 cm with up to four persons
– 7 in/18 cm fully loaded, without
level control
>Only drive through water up to a max-
imum depth of 20 in/50 cm and only
at walking speed, making sure not to
stop in the process. When equipped
with 2-axle self leveling suspension
*,
switch the vehicle to the Off-Road
setting before driving through, refer
to page100.
After leaving the water, apply the
footbrake lightly several times while
driving at low speeds so as to dry
the brakes by braking and to prevent
decreased braking action due to wet-
ness.
Back onto paved road In recommending that you observe the
following points after driving on adverse
road surfaces, it is not as a beauty
treatment for your BMW. Instead, it is
intended for the maintenance of driving
safety:
>Clean the worst of the dirt from the
body and inspect the undercarriage
for damage
>Clean mud, snow, ice etc. from the
wheels and tires and check the
wheels for damage
>Check to determine whether rocks,
gravel or accumulations of dirt on the
brake rotors and calipers could influ-
ence braking performance. Remove
all such foreign objects
>In order to clean the brake rotors,
apply the footbrake gently several
times while driving at a low speed.
Be sure that following traffic is not
endangered by this
>For cleaning the handbrake, apply
the lever slightly at approx. 25 mph/
40 km/h and continue to drive for
approx. 200 yards/200 meters, pro-
vided that traffic conditions allow you
to do so.

Safe braking Emergency stops You brake most effectively when you
apply maximum pedal pressure in situa-
tions requiring it: emergency stops.
Since the vehicle maintains steering
responsiveness, you can nevertheless
avoid possible obstacles with a mini-
mum of steering effort.
Pulsation at the brake pedal combined
with sounds from the hydraulic circuits
indicates to the driver that ABS is in its
active mode.Brake fluid level If the brake fluid level is too low and
brake pedal travel has become longer,
there may be a defect in one of the two
brake system's hydraulic circuits.
Proceed to the nearest BMW
Sports Activity Vehicle center.
Here increased pressure on the brake
pedal may be required, and slight pull-
ing to the side and longer braking dis-
tances may result. Please remember to
adapt your driving style accordingly.<
Disc brakes When the vehicle is driven only occa-
sionally, during extended periods when
the vehicle is not used at all, and in
operating conditions where brake appli-
cations are less frequent, there is an
increased tendency for corrosion to
form on rotors, while contaminants
accumulate on the brake pads. This
occurs because the minimal pressure
which must be exerted by the pads dur-
ing brake applications to clean the
rotors is not reached.
If the brake rotors are corroded, they
will tend to respond to braking with a
pulsating effect which even extended
application will fail to cure.
When driving in wet conditions and in
heavy rain, it is advisable to apply light
pressure to the brake pedal from time
to time. Monitor traffic conditions to
ensure that this maneuver does not
endanger other road users. The heat
generated in this process helps dry the
pads and rotors to ensure that the brak-
ing force is then immediately available
when required.
Extended or steep mountain descents
should be driven in the gear in which
only minimal periodic brake application
is required. This avoids excessive strain on the brakes and possible impairment
of the braking effect.
Do not coast with the clutch
depressed or with the transmis-
sion or selector lever in neutral. Do not
drive with the engine switched off. The
engine provides no braking effect when
the clutch is depressed or the transmis-
sion is in neutral, and there is no power-
assist for braking or steering when the
engine is not running.
BMW recommends having brake
inspections performed at a BMW
Sports Activity Vehicle center only. If
you do not, parts of the 4-wheel drive
system could be damaged.
Never allow floor mats, carpets or any
other objects to protrude into the area
around the accelerator, clutch and
brake pedals and obstruct their move-
ment.<
Brake pads
For your own safety: use only
brake pads that BMW has
released for your particular vehicle
model. BMW cannot evaluate non-
approved brake pads to determine if
they are suited for use, and therefore
cannot ensure the operating safety of
the vehicle if they are installed.<
