Indicator lamp

The indicator lamp in the instrument
cluster goes out soon after you start
the engine.

If the indicator lamp flashes:
DSC is active and is regulating the drive
and braking forces.
The indicator lamp stays lit:
DSC has been switched off using the but-
ton and the stabilizing interventions are no
longer available.

Switching off DSC

Press the button; the indicator lamp comes
on and stays on.
Stabilizing interventions of the chassis con-
trol system DSC are no longer available.
However, the braking interventions that
simulate the function of the differential lock
continue to be active.

In the following exceptional circumstances,
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 sur-
faces

On sandy road surfaces

On poor surfaces with deep ruts

If the wheels churn on muddy surfaces

When driving with snow chains.

As a result of the braking interven-
tions, the brakes may be subjected to

additional loads when the system is
switched off. In order to limit the brake tem-
perature, brief automatic masking of the
brake activation is possible.
To maintain vehicle stability, always drive

with the system switched on when possi-
ble.

Switching DSC on

Press the DSC button again; the indicator
lamp in the instrument cluster goes out.
DSC is now activated.

xDrive

xDrive is the all-wheel drive system of your
BMW X3. The combined effects of xDrive
and DSC further optimize the traction and
dynamic driving characteristics. The all-
wheel drive system xDrive variably distrib-
utes the drive torque to the front and rear
axle depending on the driving situation and
prevailing road conditions.

Hill Descent Control HDC

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 conditions.
The vehicle moves at slightly more than
walking speed without active intervention
from the driver.

HDC is available for activation at vehicle
speeds below approx. 20 mph/35 km/h.
When driving down steep hills with a speed
below approx. 20 mph/35 km/h, the vehi-
cle 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 +/– buttons of the
cruise control in the steering wheel.

HDC is automatically deactivated once
vehicle speed again exceeds approx.
35 mph/60 km/h.
