DTC Dynamic Traction Control
DTC is a version of DSC in which the drive out-
put is optimized for particular road conditions,
e.g. unplowed snow-covered roads. The sys-
tem assures the maximal drive output, but with
reduced driving stability. It is therefore neces-
sary to drive with appropriate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:
> When driving in sand, on snowy inclines, in
slush or on unplowed, snow-covered road
surfaces
> When rocking a stuck vehicle free or start-
ing off in deep snow, sand or on loose
ground
> When driving with snow chains

xDrive
xDrive is the 4-wheel drive system of your
BMW. The combined effects of xDrive and DSC
further optimize the traction and dynamic driv-
ing characteristics. The 4-wheel drive system
xDrive variably distributes the drive forces to
the front and rear axle depending on the driving
situation and prevailing road conditions.
BMW X6: Dynamic Performance
Control
The concept
Dynamic Performance Control optimizes the
handling characteristic s of your BMW when
starting off, cornering, and during evasive
maneuvers. To achieve this, the system variably
distributes the drive torque of the rear axle to
the two rear wheels. This further increases the
steering precision and tracking stability of your
vehicle.
Display
The instrument panel display shows how xDrive
and Dynamic Performanc e Control are distrib-
uting the drive torque.

the greater the drive torq ue in the related wheel.
Malfunction
If xDrive and Dynamic Performance Control are
malfunctioning, the instrument panel display
appears in gray.
HDC Hill Descent Control
The concept
HDC is a system for driving downhill in steep
terrain. This system reduces vehicle speed on
steep downhill gradients, thus allowing you to
maintain even better control of your BMW
under these conditions. The vehicle moves at
approximately walking speed without active
intervention from the driver.
HDC is available for activation at vehicle speeds
below approx. 22 mph/35 km/h. When driving
down steep hills with a speed below approx.
22 mph/35 km/h, the vehicle reduces speed
automatically down to approximately walking
speed, approx. 5 mph/8 km/h, and then main-
tains this speed at a constant.
Only use HDC in transmission positions D or R.
Increasing or reducing speed
You can use the accelerator or brakes to vary
this automatically cont rolled speed within a
range extending from approx. 4 mph/6 km/h to 15 mph/25 km/h.
You can specify a target
speed within the same
range by using the lever of the cruise control.
With downhill grade over 10 Ξ you can reduce
the speed to approx. 3mph/4km/h. Pull the
lever of the cruise control beyond the resis-
tance point, arrow 3.
1 Increasing speed
2 Pull to the resistance point:
Reduce speed to approx. 4 mph/6 km/h
3 Pull beyond the re sistance point:
With downhill grade over 10 Ξ, reduce
speed to approx. 3 mph/4 km/h.
Activating HDC
Press the button; the LED lights up.
The HDC display is shown in the instrument
panel.
The LED flashes when the brakes are applied
automatically.
Deactivating HDC
Press the button again. The LED and the HDC
display go out.
HDC is automatically deactivated at speeds
over approx. 37 mph/60 km/h.

Self-leveling suspension*
Malfunction
The warning lamp for self-leveling
suspension lights up yellow and a
message is shown on the Control
Display. A malfunction has occurred in the self-
leveling suspension. Stop and check the vehi-
cle. If it is considerably lower at the rear than at
the front, and possibly also on one side – rear
left compared to rear right –, proceed to the
nearest BMW Sports Activi ty Vehicle Center or
a workshop that works according to BMW
repair procedures with correspondingly trained
personnel. Drive with a ppropriate caution in the
meantime. The vehicle has reduced ground
clearance and driving co mfort may be notice-
ably reduced. Even if th e orientation of the vehi-
cle is normal, when a malfunction is indicated
on the display, you should proceed to the near-
est BMW Sports Activity Vehicle Center or a
workshop that works according to BMW guide-
lines and uses appropriately trained personnel.
FTM Flat Tire Monitor*
The concept
The Flat Tire Monitor detects a pressure loss in
one tire by comparing the speeds of the individ-
ual wheels during driving.
In the event of a pressure loss, there is a change
in the rolling circumference and therefore the
rotation speed of the corresponding wheel. The
system detects this change and reports it as a
flat tire.
Function requirements
In order to assure the re liable reporting of a flat
tire, the system must be initialized for the cor-
rect tire inflation pressure. The initialization must be repeated after
each time the tire inflation pressure is cor-
rected and after every tire or wheel change. <
System limits
The Flat Tire Monitor cannot indicate
sudden severe tire damage caused by
outside factors and does not detect a natural,
even pressure drop in all four tires. <
In the following situatio ns, the system could be
delayed or malfunction:
> System has not been initialized
> Driving on snowy or slippery road surface
> Sporty driving style: slip in the drive wheels,
high lateral acceleration
> Driving with snow chains
*
When you are driving with the compact wheel*
the Flat Tire Monitor is unable to function.
Initializing system
The initialization finishes during driving,
which can be interrupted at any time.
When driving resumes, th e initialization is con-
tinued automatically. Do not initialize the sys-
tem when driving with snow chains
* or with the
compact wheel
*. <

The initialization finishes during driving.
Indication of a flat tire
The warning lamp lights up red. A
message appears on the Control Dis-
play. In addition, an acoustic signal
sounds. There is a flat tire or extensive inflation
pressure loss.
If you have deactivated DS C, it will be activated
automatically.
1. Cautiously reduce speed to below 50 mph/
80 km/h. Avoid sudden braking and steer-
ing maneuvers. Do not exceed a speed of
50 mph/80 km/h.
In case of further air loss of the defective
wheel, its position will be indicated to you
on the Control Display.
If the vehicle is not equipped with run-
flat tires as provided at the factory, refer to page
256, do not continue driving.
Continuing to drive with a flat tire could
cause severe accidents. <
2. At the next opportunity, check the air pres-
sure in all four tires.
If the tire inflation pressure in all four
tires is correct, the Flat Tire Monitor
may not have been initialized. The system
must then be initialized. <
3. In the event of complete tire pressure loss,
0 psi/0 kPa, you can estimate the possible
distance for continued driving on the basis
of the following guide values:
> With a light load:
1 to 2 persons without luggage:
approx. 155 miles/250 km
> With a medium load:
2 persons, cargo bay full, or
4 persons without luggage:
approx. 95 miles/150 km
> With a full load:
4 or more persons, cargo bay full:
approx. 30 miles/50 km
Drive cautiously and do not exceed
speeds of 50 mph/80 km/h or else you
run the risk of causing an accident. In the event
of pressure loss, vehicl e handling changes. This
includes reduced tracking stability in braking,
extended braking distance and altered natural
steering characteristics.
If unusual vibrations or loud noises occur while
the vehicle is being driven , this can indicate final
failure of the damaged tire. Reduce speed and
stop at a suitable location as soon as possible,
otherwise pieces of the tire could become
detached and cause an accident. Do not con-
tinue driving, but instead contact the BMW
Sports Activity Vehicle Center. <
TPM Tire Pressure Monitor*
The concept
TPM checks the tire inflation pressure in the
four mounted tires. The system reports when

Technology for comfort, convenience and safety

the tire inflation pressu
re has dropped consid-
erably in one or several tires.
Function requirements
In order to assure the re liable reporting of a flat
tire, the system must have been reset with the
correct tire inflation pressure.
Always use wheels with TPM electronics, oth-
erwise fault-free operation of the system is not
ensured.
Reset the system again after each correc-
tion of the tire inflation pressure and after
every tire or wheel change.<
System limits
TPM cannot announce sudden serious
tire damage caused by external influ-
ences. <
The system does not function properly if it has
n o t b e e n r e s e t , e . g . a f l a t t i r e i s r e p o r t e d d e s p i t e
correct tire inflation pressures.
The system is inactive and cannot display a flat
tire if a wheel has be en mounted without TPM
electronics, e.g. a compact wheel
*, or if TPM is
temporarily interfered wi th by other systems or
devices which use the same radio frequency.
Status display on Control Display
The tire and system stat us is indicated by the
color of the tires.
TPM takes the fact that the tire pressure
changes during driving in to account. A correc-
tion is only required if requested by TPM with
the color.
Green
The tire pressure matche s the learned set state.
"TPM active" is displayed on the Control Dis-
play.
One wheel is yellow
Flat tire or a major drop in inflation pressure in
the indicated tire. A me ssage appears on the
Control Display.
All wheels are yellow
Flat tire or a major drop in inflation pressure in
several tires. A message appears on the Control
Display.
Gray
The system cannot detect a flat tire.
Reasons for this can be:
> TPM is being reset
> Temporary interference due to systems or
devices which use the same radio fre-
quency
> Malfunction

Explanation according to the NHTSA/
FMVSS 138 Tire Pressure Monitoring
Systems
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle plac-
ard or tire inflation pressu re label. (If your vehi-
cle has tires of a different size than the size indi-
cated on the vehicle plac ard or tire inflation
pressure label, you should determine the
proper tire inflation pr essure for those tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illumi nates a low tire pres-
sure telltale when one or more of your tires is
significantly underinflate d. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres-
sure. Driving on a significantly underinflated tire
causes the tire to overhe at and can lead to tire
failure. Underinflation also reduces fuel effi-
ciency and tire tread life, and may affect the
vehicle's handling and stopping ability.
Please note that the TP MS is not a substitute
for proper tire maintenance, and it is the driver's
responsibility to maintain correct tire pressure,
even if underinflation has not reached the level
to trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale. When the system
detects a malfunction, the telltale will flash for
approximately one minute and then remain con-
tinuously illuminated. Th is sequence will con-
tinue upon subsequent vehicle start-ups as
long as the malfunction exists. When the mal- function indicator is illuminated, the system
may not be able to detect or signal low tire pres-
sure as intended. TPMS malfunctions may
occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to
continue to function
properly.
Active steering*
The concept
The active steering active ly varies the steering
angle of the front wheels in relation to the steer-
ing wheel movements. In addition, it also varies
the steering force required for steering depend-
ing on the vehicle's speed.
When you are driving in the low road speed
range, e.g. in a town or when parking, the steer-
ing angle increases, i.e. the steering becomes
very direct. In the higher speed range, on the
other hand, the steering angle is reduced more
and more. This improves the handling capability
of your BMW over the entire speed range.
In critical situations, the system can make tar-
geted corrections to th e steering angle pro-
vided by the driver and thus stabilize the vehicle
before the driver intervenes.
Malfunction
The warning lamp lights up yellow
and a message is shown on the Con-
trol Display. The active steering is
defective or has been temporarily
deactivated. At low speeds, greater steering
wheel movements are required, whereas at
higher speeds, the vehicle reacts more sensi-
tively to steering wheel movements. The stabil-
ity-promoting intervention can also be deacti-
vated. Proceed cautiously and drive
defensively. If active st eering is defective, have
the system checked.

the upholstery in the center of the steering
wheel, on the instrument cluster, the doors, and
the roof pillars as well as
the sides of the head-
liner. Do not attempt to remove or dismantle the
steering wheel. Do not touch the individual
components immediately after the system has
been triggered, because there is a danger of
burns.
In the event of malfunctions, deactivation, or
triggering of the airbag restraint system, have
the testing, repair, remova l, and disposal of air-
bag generators executed only by a BMW Sports
Activity Vehicle Center or a workshop that
works according to BMW repair procedures
with correspondingly trained personnel and has
the required explosives licenses. Otherwise
unprofessional attempts to service the system
could lead to failure in an emergency or undes-
ired airbag triggering, either of which could
result in personal injury. <
Warnings and information on the airbags is also
provided on the sun visors.
Automatic deactivation of front
passenger airbags
The occupation of the seat is detected by eval-
uating the impression on the occupied seat sur-
face of the front passeng er seat. The front and
side airbags on the front passenger side are
activated or deactivated accordingly by the sys-
tem.
The current status of the front passenger
airbag, i.e. deactivated or activated, is
indicated by the indicator lamp over the interior
rearview mirror, refer to Operating state of front
passenger airbags in the following. <
Before transporting a child on the front
passenger seat, read the safety informa-
tion and follow the inst ructions under Trans-
porting children safely, refer to page 61.
When teenagers and adults assume certain sit-
ting positions, this can cause the front and side
airbags to deactivate. The indicator lamp for the
front passenger airbags lights up when this
occurs. In these cases, change the sitting posi-
tion so that the front passenger airbags are acti-
vated and the indicator la mp goes out. If the
desired status cannot be produced by changing the sitting position, transport the correspond-
ing person on the rear se
at. Do not fit seat cov-
ers, seat cushion padding, ball mats or other
items onto the front passenger seat unless they
are specifically recomme nded by BMW. Do not
lay objects under the seat which could press
against the seat from below. Otherwise a cor-
rect evaluation of the occupied seat surface
cannot be ensured. <
Operating state of front passenger
airbags
Depending on the vehicle's equipment, the
arrangement of the switches and indicator
lamps may differ somewhat.
The indicator lamp for the front passenger air-
bags indicates the operating status of the front
and side airbags on the front passenger side
depending on the seat occupation. The indica-
tor lamp shows whether the front passenger
airbags are activated or deactivated.
> The indicator lamp light s up when a child in
a child restraint device intended for the pur-
pose is properly detected on the seat.
The front and side airbags on the front pas-
senger side are not activated.
Most child's seats are detected by the
system. Especially the child's seats
required by the NHTSA at the time the vehi-
cle is manufactured. Af ter installing a child's
seat, make sure that the indicator lamp for
the front passenger airbags lights up. This
indicates that the child's seat has been
detected and the front passenger airbags
are not activated. <
> The indicator lamp does not light up when,
for example, a correctly seated person of
sufficient height is detected on the seat.

Things to remember when driving
144
Driving on poor roads
Your BMW is at home on all roads and surfaces.
It combines a 4-wheel drive system with the
advantages of a normal passenger car.Do not drive on unpaved terrain, as other-
wise the vehicle may be damaged. <
When you are driving on poor roads, there are a
few points which you shou ld strictly observe for
your own safety, for that of your passengers,
and for the safety of the vehicle:
> Familiarize yourself wi th the vehicle before
driving off and avoid taking risks at all costs.
> Adapt your driving spee d to the road condi-
tions. The steeper and rougher the road
surface is, the lower the speed should be.
> If you want to drive on very steep uphill or
downhill gradients, ma ke sure beforehand
that the engine oil and coolant levels are
near the MAX mark, refer to page 259.
BMW X5: you can operate your vehicle on
uphill and downhill gradients with a maxi-
mum slope of 50 %.
> On very steep downhill slopes, use Hill
Descent Control HDC, refer to page 98.
BMW X5: it is possible to start off on inclines
of up to 33 %. The permissible body roll is
50 %.
> While driving, watch carefully for obstacles
such as rocks or holes. Try to avoid these
obstacles whenev er possible.
> Make sure that the undercarriage does not
touch the ground, for example on crests and
bumpy roads. The ground clearance of the
vehicle is a maximum of approx. 8 in/20 cm.
Please note that the ground clearance can
vary depending on lo ading and the driving
conditions of the vehicle.
> Only drive through road surface water up to
a maximum water depth of
> BMW X5 20 in/50 cm
> BMW X6 17 in/45 cm
and only drive at walking speed; do not
remain stationary. >
After driving through water at low speed,
lightly press the brake pedal several times
to dry the brakes and to prevent the braking
effect from being reduced by wetness.
> Depending on the condition of the surface,
it may be practical to briefly activate DTC,
refer to DTC Dynamic Traction Control on
page 97.
> If the drive wheels spin on one side, depress
the accelerator pedal su fficiently so that the
driving stability control systems can distrib-
ute the drive forces to the individual wheels.
Please note the following points after driving on
poor roads to maintain the driving safety of your
BMW:
> Clean the coarsest dirt from the body.
> Clean mud, snow, ice etc. from the wheels
and tires and check the tires for damage.
