Signal tones
Even with PDC, final responsibility The concept
for estimating the distance
The distance from an object is indicated
in front with a higher intermittent tone,
and at the rear with a lower intermittent
tone. As the distance between vehicle
and object decreases, the intervals
between the tones become shorter.
The signal tone becomes continuous
once the distance to the nearest object
falls to below roughly 1 ft/30 cm.
The ABS Antilock Brake System keeps
between the vehicle and any obstruc-
tions always remains with the driver.
Even when sensors are involved, there
is a blind spot in which objects cannot
be detected. This applies especially in
those cases where the system
the wheels from locking during braking,
thereby enhancing active driving safety.
The vehicle continues to be steerable
during hard braking.
ABS also includes EBV Electronic
brake-force distribution.
approaches the physical constraints of
ultrasonic measurement, as occurs with
tow bars and trailer couplings, and in
the vicinity of thin or wedge-shaped
objects. Low objects already displayed,
e.g. a curb, can also disappear from the
detection area of the sensors again
before a continuous tone sounds.
Loud sources of sound, inside and out-
side the vehicle, could drown out the
PDC signal tone.<
Safe braking, refer to page 139.
EBV Electronic brake-force
distribution
EBV controls the brake system's appli-
cation pressure at the rear wheels to
ensure stable deceleration.
The warning signal is canceled after
approx. 3 seconds if you are moving
parallel to a wall.
If there is a malfunction of the system:
The indicator lamp flashes and a short
steady signal tone is sounded
DBC Dynamic Brake Control

if you activate PDC with the button
when you select reverse for the first
time after switching on the ignition
if a malfunction occurs while the PDC
system is active.
The Dynamic Brake Control actively
supports the driver in dangerous brak-
ing situations. When you apply the
brake pedal rapidly, the system
increases the braking effect with low
pedal pressure so that the shortest
possible braking distance is achieved.
This system exploits all of the benefits
provided by ABS.
Keep the sensors clean and free of ice
or snow in order to ensure that they will
continue to operate effectively.
Do not apply high pressure spray to the
sensors for a prolonged period of time.
Keep the spray at least 4 in/10 cm away
from the sensors.
>
Switch the system off and have the
cause of the malfunction corrected by
your BMW Sports Activity Vehicle cen-
ter.
Do not reduce the pressure on the
brake pedal for the duration of the
brake application. DBC is deactivated
when you release the brake pedal.

Automotive readers have rated 2004 BMW X5 3.0i 4.4i 4.8is E53 Owners Manual 4.5 out of 5.0 based on 4 product reviews. this article is so important for x5 owners, thanks for it
very good and very helpful
thank you
lost book.. this is a great service
I own a 2004 BMW X5 4. 4 and the ccv vent valves keep popping off causing the engine to burn oil and grey smoke to become out tge tail pipe.
