BMW 2013 X5 - Manual (Page 108)

Depending on the vehicle load, the vehicle may
roll back slightly.
Driving off without delay
After releasing the foot brake, start driving
without delay, since the drive-off assistant will
not hold the vehicle in place for more than ap‐
prox. 2 seconds and the vehicle will begin rolling
back.◀
Self-leveling suspension
The concept
The self-leveling suspension on the rear axle
assures a continuous ground clearance.
To do so, the height of the vehicle is measured
by sensors at both rear wheels.
If the actual height deviates from the defined
height, such as due to cargo in the vehicle, this
difference is compensated very quickly. In ad‐
dition, spring motions resulting from cornering
or irregularities in the road surface are reduced
to a minimum.
The system works automatically.
Malfunctions
Malfunctions are displayed via Check Control,

Active steering
The concept
The active steering actively 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 speed range, for
instance in a town or when parking, the steering
angle increases, i.e., steering becomes very di‐
rect. In the higher speed range, on the other
hand, the steering angle is reduced more and
more. This improves the handling of your vehicle
over the entire speed range.
In critical situations, the system can make tar‐
geted corrections to the steering angle provided
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 Control
Display. The active steering is defec‐
tive or has been temporarily deacti‐
vated. At low speeds, greater steering wheel
movements are required, whereas at higher
speeds, the vehicle reacts more sensitively to
steering wheel movements. The stability-pro‐
moting intervention can also be deactivated.
Proceed cautiously and drive defensively.
Deactivation
Active steering deactivates in order to carry out
an initialization. This deactivation is displayed by
means of a message. The initialization can take
several minutes.
If the message does not disappear during the
current trip, have the system checked.
Defect
In the event of a defect, a corresponding text
message is displayed. Have the system
checked.
