jointly. These systems do not take their cus-
tomary stabilizing actions.
To increase vehicle stability, reactivate DSC as
soon as possible.
Activating DSC
Press the button again; the indicator lamp in the
instrument cluster goes out.
For monitoring purposes
When the indicator lamp flashes:
DSC is controlling the drive and braking
forces.
When the indicator lamp lights up:
DSC is deactivated.
Dynamic Traction Control DTC
DTC is a variation of DSC that is optimized for
forward momentum for particular road condi-
tions, e.g. unplowed snow-covered roads. In
this mode, the system assures maximum for-
ward momentum, but with limited driving stabil-
ity. For this reason, drive with corresponding
caution.
In the following exceptional circumstances, it
may be useful to temporarily activate DTC:
>When driving on snow-covered inclines, in
slush, or on unplowed, snow-covered roads
>When freeing a stuck vehicle or starting up
in deep snow, sand, or on a loose ground
surface
>When driving with snow chains
*
Activating DTC
Press the button; the DTC indicator lamp in the
instrument cluster lights up.
For monitoring purposes
When the indicator lamp flashes:
DTC is controlling the drive forces and
braking forces.
When 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 all-wheel drive system of your X3.
The combined effects of xDrive and DSC fur-
ther optimize the traction and dynamic driving
characteristics. The all-wheel drive system
xDrive variably distributes the drive torque 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 hill descent assistance that
reduces the speed on steep downward inclines
and makes it even easier to control the driving
characteristics of your BMW under these condi-
tions. The vehicle moves at slightly more than
walking speed without active intervention from
the driver.
You can activate HDC at vehicle speeds below
approx. 20 mph/35 km/h. If it is traveling down a
steep slope at a speed below approx. 20 mph/
35 km/h, the vehicle then automatically decel-
erates down to slightly more than walking
speed, approx. 5 mph/8 km/h, and then keeps
this speed 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 +/– buttons of the cruise
control on the steering wheel.

After releasing the brake, start driving immedi-
ately; otherwise, the acceleration assistant will
no longer hold the vehicle after approx. 2 sec-
onds and the vehicle will start to roll back-
ward.<
Malfunction
The warning lamp for the brake system
lights up in yellow. The acceleration
assistant has failed. The vehicle will not
be held after the brake is released. Have the
system checked as soon as possible.
Flat Tire Monitor FTM*
The concept
The Flat Tire Monitor keeps track of the infla-
tion pressures in the four mounted tires as you
drive. The system triggers an alert whenever
the inflation pressure in one tire drops signifi-
cantly in relation to the pressure in another tire.
When a loss of pressure occurs, the rolling
radius changes and with it, the rotational speed
of the wheels. This change is detected and sig-
naled as a flat tire.
Functional requirement
To ensure the reliable signaling of a flat tire, the
system must be initialized at the correct tire
inflation pressure.
The initialization must be carried out after
each correction of the tire inflation pres-
sure and after every tire or wheel change.<
System limits
The Flat Tire Monitor cannot predict sud-
den severe tire damage caused by out-
side 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 the system has not been initialized
>When driving on snow-covered or slippery
road surfaces>Sporty driving style: slip in the drive wheels,
high lateral acceleration.
>When driving with snow chains
*
When driving with a compact wheel, the Flat
Tire Monitor cannot operate.
Initializing system
The initialization is completed while driv-
ing and can be interrupted at any time.
The initialization automatically continues when
driving resumes.
Do not initialize the system when driving with
snow chains
* or with a compact wheel.<
1.Start the engine just before driving, but do
not begin to drive.
2.Press the button for at least 4 seconds, but
not longer than 2 minutes. After the button
is released, the indicator lamp in the instru-
ment cluster lights up yellow for a few sec-
onds.
3.Begin driving.
The initialization is completed while driving,
without requiring any further input from you.
Indication of a flat tire
The warning lamp lights up red. In addi-
tion, an acoustic signal sounds. There is
a flat tire or extensive inflation pressure
loss.
1.Reduce speed and stop the vehicle care-
fully. Avoid sudden braking and steering
maneuvers.
2.Identify damaged tire.
If identification is not possible, con-
tact your BMW Sports Activity Vehi-
cle Center.<

Snow chains*
Only certain fine-link snow chains are tested,
classified as road-safe, and recommended by
BMW. You can obtain a list of these from your
BMW Sports Activity Vehicle Center. It is only
permissible to use them in pairs and on the rear
wheels.
Follow the manufacturer's instructions when
installing snow chains.
Do not exceed a vehicle speed of 30 mph/
50 km/h with snow chains mounted.
Do not initialize the Flat Tire Monitor

When you are driving with snow chains, it can
be beneficial to temporarily activate DTC, refer
to page51.<
