The ! indicator lamp for ABS equipment
is shown in grey in the status area of the on-

plemented by the s, r or u indi-
cator lamps for towing vehicles and/or trail-
ers/semitrailers.

Braking with anti-lock protection
G
WARNING
The wheels of the trailer/semitrailer may
lock when braking and the vehicle combina-
tion may become unstable if:
the trailer/semitrailer does not have ABS
R
the ABS of the trailer/semitrailer has
R
failed
ABS has failed completely
R
As a result, you could lose control of the
vehicle and cause an accident.
Always adapt your driving style to the pre-
vailing road and weather conditions and
maintain a sufficient, safe distance from
other road users. Avoid full brake applica-
tions; except in emergency situations.
Anti-lock protection improves the directional
stability and the steerability of the vehicle or
tractor/trailer combination during braking.
If you fail to adapt your driving style or if you
are inattentive, the driving safety systems can
neither reduce the risk of an accident nor
override the laws of physics. Driving safety
systems are merely aids designed to assist
driving. You are responsible for the distance to
the vehicle in front, for vehicle speed and for
braking in good time. Always adapt your driv-
ing style to the prevailing road and weather
conditions and maintain a sufficient, safe dis-
tance from other road users. Drive carefully.
When ABS is intervening:
X
Continue to depress the brake pedal until
the braking situation is over.
When ABS is intervening, the continuous
brake is switched off. The à indicator
lamp in the instrument cluster remains on.
During a full brake application:
X
Depress the brake pedal with force.
If you want to drive the tractor vehicle with a
trailer/semitrailer with ABS or an electronic
brake system:
X
Connect a control cable to the socket or to
Y
the ABS plug ( page 134).
If you want to drive the semitrailer tractor
vehicle without a trailer or with a trailer with-
out ABS:
X
Insert the control cable into the blank
socket.
Deactivating/activating ABS
G
WARNING
If ABS is deactivated, the wheels may lock
when braked. As a result, the vehicle can no
longer be steered. There is an increased risk
of skidding and an accident.
Always leave ABS on when driving on roads
and firm surfaces.
ABS is automatically activated when you start
the engine. By deactivating ABS, it may be
