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
*
Activating DTC
Press the button briefly; the DTC indicator lamp
in the instrument cluster lights up.
For better control
The indicator lamp flashes:
DTC controls the drive forces and
brake forces.
The indicator lamp lights up:
DTC is activated.
Deactivating DTC
Press the button again; the DTC indicator lamp
in the instrument cluster goes out.
xDrive
xDrive is the 4-wheel drive system of your X5.
The combined effects of xDrive and DSC fur-
ther optimize the traction and dynamic driving
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.
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 position D or R.
Increasing or reducing speed
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 lever of the cruise control.

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 Activity Vehicle Center or
a workshop that works according to BMW
repair procedures with correspondingly trained
personnel. Drive with appropriate caution in the
meantime. The vehicle has reduced ground
clearance and driving comfort may be notice-
ably reduced. Even if the 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 keeps track of the infla-
tion pressures in the tires as you drive. The sys-
tem provides an alert whenever the inflation
pressure drops significantly in relation to the
pressure in another tire.
In the event of a pressure loss, the rolling radius
and therefore the rotation speed of the wheels
change. This change is detected and is
reported as a flat tire.
Functional requirement
In order to assure the reliable 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 situations, 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, the initialization is con-
tinued automatically. Do not initialize the sys-
tem when driving with snow chains
* or with the
compact wheel
*.<
iDrive, for explanation of concept, refer to
page16.

Recommended tire brands
Certain tire makes are recommended by BMW
depending on the tire size. You can recognize
these from the clearly visible BMW marking on
the tire sidewall.
When used properly, these tires comply with
the most demanding standards for safety and
vehicle response.
Run-flat tires
When mounting new tires, or changing from
summer to winter tires or vice versa, use run-flat
tires for your own safety. In addition, no spare
tire is available in case of a flat tire. Your BMW
Sports Activity Vehicle Center will be happy to
advise you.
For safety reasons, BMW recommends
that you do not have damaged run-flat
tires repaired; they should be replaced.<
Special characteristics of winter tires
BMW recommends winter tires for use in cold
winter driving conditions. Although all-season
M+S tires provide better winter traction than
summer tires, they generally fail to provide the
same levels of cold-weather performance as
winter tires.
Pay attention to speed
Always observe the maximum permissi-
ble speed for the winter tires, otherwise
tire damage may occur, which can result in acci-
dents.<
Storage
Store wheels and tires in a cool, dry place with
as little exposure to light as possible. Always
protect tires against all contact with oil, grease
and fuels. Do not exceed the maximum tire
inflation pressure indicated on the side wall of
the tire.
Rotating wheels between axles
BMW does not recommend moving the front
wheels to the rear or vice versa, as otherwise
the handling characteristics may be impaired.
Snow chains*
BMW only tests certain fine-link snow chains,
classifies them as road-safe and recommends
them. Your BMW Sports Activity Vehicle Center
can provide you with this information.
Use is only permissible in pairs on the rear
wheels.
Observe the manufacturer's instructions when
mounting snow chains. Do not exceed a speed
of 30 mph/50 km/h with the chains mounted.
After mounting snow chains, do not ini-
tialize the Flat Tire Monitor
*, as otherwise
incorrect displays can occur.
When you are driving with snow chains, it can
be beneficial to activate DTC briefly, refer to
page85.<
